The fine Dendrobium which forms the subject of our

illustration was discovered in 1905 in Indo-China. The

precise locality has not so tar been indicated, but it is said

to occur at about 1,750 feet above sea-level. It was

introduced to cultivation by Mr. G. Bronckart along with

another Indo-Chinese species, D. Bronckartii, De Wildem.,

ficured at t. 8252 of this work, which is a native of Annam.

The nearest ally of D. Dartoisianum is D. tortile, Lindl., a

native of Chittagong and Burma, figured at t. 4477 of this

work; the stems of D, Dartoisianum are, however, longer

and more cylindric than those of D. tortile, the undulate

sepals and petals are more markedly twisted, the base of

the lip is narrower and more convolute and the coloration

of the flowers is different. The plant from which our

figure has been prepared was purchased for the Kew collection

in 1906 from Mr. M. Verdonck, Ghent. It has been grown

and flowered in a tropical house at Kew under the con-

ditions suitable for the species of the group to which

D. nobile, Lindl., belongs; during winter it is rested in an

airy greenhouse.

The plant here figured is a native of Alaska, where,

according to Professor Sargent, it grows along the borders

of upland meadows, opening its flowers in succession during

several weeks in summer. In addition to C. pyrolaeflorus

there is, according to Professor Greene, another species of

Cladothamnus, C. campanulatus, which inhabits the high —

mountains of British Columbia and Washington, and has

been confounded with the Alaskan plant. C. campanulatus,

Greene, is readily distinguished from C. pyrolaeflorus by

having the petals united in a short tube; the anthers too

are said to open differently. There is no exampie of this

species, the characters assigned to which would appear to

exclude it from the genus, in the herbarium at Kew; the

only specimen in the collection to which the name

C. campanulatus is attached is undoubtedly C. pyrolae-

florus, as indeed are all the specimens at Kew collected in

British Columbia and Washington. C. pyrolueflorus was

January, 1911.

discovered by Dr. C. H. Martens in the Island of Sitka in

1828, but is rarely met with in gardens. The material on

which our illustration is based was obtained from a plant

which flowered with Mr. T. Smith, Daisy Hill Nursery,

Newry, in June, 1910. In localities otherwise suitable, the

cultivation of C. pyrolaeflorus, if grown under the conditions

necessary for Lhododendron hirsutum, is, Mr. Smith informs

us, not attended by any difficulty.

Descriprion.— Shrub; 4-10 ft. high; branehes slender,

when young reddish and glabrous except for two lines of

very short reddish hairs, when mature covered with grey

or tawny bark. Leaves almost sessile, lanceolate or obovate-

lanceolate, gradually narrowed to the base, gland-tipped,

2-1 in. long, 4-3 in. wide, thin, glabrous, pale green.

Flowers terminal on leafy often contracted branches,

solitary or with a few additional blooms in the axils of the

uppermost leaves, nodding; pedicels short or at length 2 in.

long. Calyzx-lobes leafy, lanceolate or linear-oblong, gland-

tipped, often unequal, about 2 in. long, narrowed above the

base and ciliolate on both surfaces. Petals oblong, blunt,

% in. long, thin, soon disappearing, yellowish-red or

yellowish-rose. Anthers opening at the apex by wide

chinks. Sty/e incurved, ultimately almost circinate, per-

sistent. Capsule subglobose, under 4 in. wide, septicidally

3-5-valved. Seeds minute, compressed, ovoid or ellipsoid.

The Aguilegia which forms the subject of our plate is a

white-flowered form of the Japanese A. flabellata, Sieb. &

Zuce., which Franchet & Savatier in their Enumeratio

Plantarum Japoniae, p. 11, have treated as identical with

A. glandulosa, Fisch. This view is not, however, generally

accepted ; indeed the most recent view, advanced by Finet

and Gagnepain (Contrib. Fl. As. Or. fase. i. p. 155), is that

A, flabellata may be no more than a variety of A. sibirica,

Lamk, characterised by shorter stems and larger cauline

leaves, and by having the limb of the petals not much

shorter than the sepals. From the gardening point of

view, however, A. flabellata must be regarded as sufficiently

distinct from A. sibirica to deserve separate treatment. The

stems of A. flabellata are generally three-flowered, having a

terminal and two axillary flowers; of these the terminal

opens first and then the lower of the axillary ones. The

abrupt curve at the junction of the claw and blade imparts

a cordate appearance to the base of the sepals. The plant

from which the material for our figure was obtained

flowered in the garden of Canon Ellacombe at Bitton, near

Bristol, in May, 1909. The species thrives in a mixture of

loam and peat. |

DescripTion.—IHerb ; rootstock ascending, woody, simple

According to the arrangement adopted by Mr. Baker in

the Handbook of the Amaryllideae the genus Phaedranassa

includes four species from the Andes of Ecuador or

Colombia, with a filth, the subject of our plate, which is

a native of Costa Rica. One of the Andean species,

P. chloracra, Herb. (sometimes written “ chloracea ”), is not

uncommon in collections in a variety of forms which differ

mainly as to the number, size and colour of their flowers.

To some of these forms distinctive names have been given,

and one of them has been figured at t. 5361 of this work

as P. obtusa, Herb, ‘To this rather variable species

P. Carmioli, here figured, is closely allied, The mem-

branous margins of the perianth-lobes in our species overlap

and, while not organically united, mutually adhere. On

this account an appearance of having a long corolla tube

with short perianth-lobes, in place of the short tube charac-

teristic of all the Andean forms, is imparted to the Costa

Rica plant, which was introduced to cultivation by Mr.

Janvary, 1911. .

Jules Carmiol and was first flowered, in 1867, by the late

Mr. Wilson Saunders. It has flowered since then with

Mr. J. O’Brien, Harrow-on-the-Hill, with Mr. A. Worsley,

Isleworth, with Mr. W. E. Ledger, Wimbledon, and possibly

elsewhere. The plant from which our figure has been pre-

pared flowered in March, 1910, with Mr. W. E. Gumbleton,

to whose garden at Belgrove, Queenstown, the bulb had

been sent two years previously from that of Mr. Ledger,

who, while failing with the other species, has, he informs

us, once flowered the Ecuadorean P. viridiflora, Baker, and

has found it comparatively easy to flower P. Carmioli.

The plant thrives wel! in a cool stove, and with care may

succeed in an ordinary heated greenhouse ; it is not fasti-

dious as to soil, and grows satisfactorily in a mixture of

peat or leaf mould and yellow loam, to which sand should be

added. It is deciduous and requires complete rest after the

leaves die down. The tall flower stalk precedes the leaves,

which, however, develop while the plant is in flower.

Descriprion.— Herb ; bulb nearly globose, 2-3 in. wide,

abruptly narrowed to a short neck and clothed with brown

membranous sheaths. Leaves 1-3, appearing during flower-

ing time, oblanceolate, obtuse, 14 in. long, about 2 in. wide,

The handsome species here figured was first discovered

by the Abbé David in June, 1869, in the mountains of

Moupine. Since then it has been met with on Mount Omi

in Szechuan by the Rev. E. Faber, in the Patung district

of Hupeh by Mr, A. Henry, and in valleys on the eastern

flank of the Li-Kiang range in North-western Yunnan by

Mr. G. Forrest. It was also found again on Mount Omi

by Mr. E. H. Wilson when collecting on behalf of Messrs.

J. Veitch & Sons, in whose nursery at Coombe Wood

Fesruary, 1911.

plants raised from seed obtained by Wilson have proved

quite hardy. From one of these plants, which flowered

in July, 1909, was obtained the material on which our

figure is based. The genus Meliosma has a special interest

for growers of ornamental shrubs owing to its being the

only genus of the family Sabiaceae members of which can

be grown in the open air in the average climate of Great

Britain. Indeed, prior to the introduction of JL euneifolia,

the only one that had flowered in England was M. myriantha,

Sieb. & Zuce., which is, however, much more tender, and

is only suitable for the mildest parts of this country.

Botanically the two species are very closely allied, and our

plant differs chiefly from M. myriantha, which is a native

of Japan and Corea, in having the leaves narrowly cuneate

at the base. Another very nearly allied species is M.

dilleniaefolia, Wall., from Northern India; from this latter,

which is not hardy, our plant is readily distinguished by

its smaller leaves, which are glabrous except on the mid-

rib and lateral nerves. A third species, M. Veitchiorum,

Hemsl. (Kew Bulletin for 1906, p. 155, and for 1910,

p. 173, with plate), from the highlands of Central China,

also nearly allied but with much larger and entire leaflets,

shares with our plant the advantage of being hardy ont of

doors in Southern England. There is a considerable degree

of variation in the amount of tomentum on the ovary in

M. cuneifolia; the original specimens on which the species

was based have distinctly pubescent ovaries, while those

raised from Wilson’s seed have the ovaries quite glabrous.

Intermediate conditions, however, occur, and in other

respects the specimens are identical. In a wild state

M. cuneifolia attains the dimensions of a tree; in cultiva-

tion the plants, which now flower annually in July, form

healthy bushes 4-5 feet high. They have not. yet ripened

fruits, so that for their propagation recourse will probably

have to be had to layering.

Derscriprion.— Tree or shrub; bark glabrous. Leaves

narrowly obovate-cuneate, acute or at times shortly and

abruptly acuminate, gradually narrowed to the base,

margin repandly toothed, 24-7 in, long, 4-3 in. wide, firm,

The striking Kennedya which forms the subject of our

figure was raised at Kew from seed purchased in 1908

from Mr. J. Staer, Wahroonga, New South Wales. The

plant from which the material for our plate was obtained has

grown vigorously in a greenhouse, twining along a rafter

after the manner of AK. ruhicunda, Vent. It flowered for

the first time in April, 1910, and has been identified by

Mr. Craib, from the original description, with K. Beckaiana,

F. vy, Muell., a species based on material collected by Mr.

W. Webb in South-western Australia inland from King

George’s Sound, of which there is no authentic specimen

in the herbarium at Kew. It appears to be the largest

Fesrvary, 1911.

flowered of the Kennedyas so far introduced to cultivation,

and is most nearly allied to A. macrophylla, Benth., but is

readily distinguished by its smaller leaflets, its shorter

2-flowered peduncles, its stalked ovary and its more

sparing pubescence. From K. rubicunda, above mentioned,

it differs in having constantly 2-flowered peduncles and a

glabrous pistil; the same characters separate it from A,

nigricans, Lindl., a species figured at t. 3652 of this work.

Desoription.—Herb, climbing, perennial; branches

slender, reddish, almost glabrous. Leaves pinnately 3-

foliolate ; stipules lanceolate, acute, 3 lin. long, rather

rigid, becoming deflexed; petioles up to 2 in. long, chan-

nelled above; leaflets shortly stalked, tips rounded or

almost truncate, bases obtuse or almost truncate, up to 3 in.

long, 2 in. wide, firm, glabrous on both. sides; terminal

leaflet obovate or obovate-elliptic, about 10 lin. remote from

the elliptic, slightly unequal lateral ones; lateral nerves

5-6 on each side, curved along the margin and like the

secondary veins prominent above and distinct beneath ;

stipels of lateral leaflets 24 lin. long, those of terminal

leaflet shorter. Peduncles axillary, 2-flowered, 5 lin. long,

with a rather flattened rigid involucre about 4 in. wide

composed of 2 connate acute ciliate bracts; pedicels

sparingly hairy, shorter than the peduncles. Calyx 2-

lipped, as long as the pedicel, green with reddish markings

at the base between the lobes, sparingly pubescent outside,

silky hairy within; upper lip ovate, shortly 2-toothed,

lower as long, with 3 rather pointed wide lanceolate lobes.

Corolla much exserted, about 14 in. long, petals of about

the same length, red except for a greenish-yellow, dark-

margined patch at base of standard; standard reflexed,

ovate, obtuse, over 1 in. wide, slightly auriculate and

In 1892 the late Dr. M. T. Masters gave a description in

the Gardeners’ Chronicle of an interesting hybrid which

had been raised by Messrs. Clibran. The parents of this

hybrid were Urceolina pendula, Herb., figured at t. 5464,

and Eucharis grandiflora, Planch., figured at t. 4971 of

this work; the name given to the plant was Urceocharis

Clibranit. Two years ago the plant now figured was

acquired for the Kew Collection by purchase from Messrs.

Sander & Sons, St. Albans. This plant had been for-

warded from Peru by the firm’s collector, Mr. Forget, who,

it is understood, had met with it in a wild state and in a

remote part of that country. It flowered in a moist

tropical house at Kew in July, 1909; another specimen,

identical in every respect, flowered at St. Albans in

January, 1910. So nearly allied to Ureeocharis Clibrani,

Mast., is this Peruvian form, which Mr. Wright has

described as Uvreeocharis edentata, that there is hardly

room for doubt as to its being another hybrid, perhaps

identical as to parentage with Messrs. Clibran’s plant, but

Fesrvary, 1911,

in this case probably a natural one. The two plants

referred to Urceocharis have a perianth with a narrowly

cylindric tube and a campanulate limb, the lobes of which

curve outwards at the apex only as in Urceolina, and not,

asin Eucharis, almost at right angles to the tube. They

further agree with Urceolina in being deciduous. The

flowers of Urceolina are either devoid of a staminal corona

or possess one that is quite rudimeutary ; those of Hucharis

have a distinct corona with free teeth between the bases

of the filaments. In the hybrid raised by Messrs. Clibran

there are two such teeth about one-third the length of the

filaments between each pair of stamens. But in the pre-

sumably wild plant sent by Forget from Peru, which in

every other respect is indistinguishable from Lrceocharis

Clibrani, there is no trace of these appendages,

The little Cherry here figured was acquired for Kew

from Zoeschen in 1900 and has been grown in the Prunus

collection ever since. It is a form of P. microcarpa,

C. A. Mey., originally described from specimens collected on

Mount Bashbarmak, north of Baku, which represent a state

with glabrous leaves and finely pubescent young twigs. A

state with rigid divaricate or tortuous branches, distinctly

pubescent all over, was later treated by Boissier and Hauss-

knecht as a distinct species, Cerasus tortuosa. The same

authors based on specimens from South Persia, more diffuse

in habit and with smaller leaves and flowers, another species,

Cerasus diffusa. But Bornmueller, who collected P. micro-

carpa on the hills around Erbil in North-eastern Mesopotamia,

found the plant to vary, in the same locality, as to pubes-

cence, length of fruit-stalk and colour of fruit. Dr. Stapf,

who knows P. microcarpa on the hills and mountains near

Fesrvary, 1911.

to and southwards from Shiraz, where it usually forms a

smal shrub with stiff spreading or tortuous branches, found

it as variable there as in Mesopotamia as regards pubescence

and fruit. Herbarium material shows that from Syria and

Western Kurdistan to Chorassan and Southern Persia it 1s°

everywhere as variable. Dr. Stapf therefore concludes that

P. microcarpa should be treated as a species very variable

not only in habit and stature, which depend greatly on

the physical conditions under which it grows, but as to

pubescence, length of fruit-stalk, size of leaf and size and

colour of fruit which vary independently. The form depicted

represents a state which most resembles Cerasus tortuosa,

Boiss. & Hausskn., but differs therefrom in having, even

in the unfolding buds, practically glabrous leaf-blades,

though the petioles, like the twigs, are pubescent. This

form comes from Asia Minor. Under cultivation it loves

sunshine and should be given a scuthern exposure. It

appears perfectly hardy and flowers prettily in May.

Under our dull skies it fails to fruit freely, and such fruits

as do form are liable to fall while still green.

DEscrIPTION.—Shrub, often dwarf, at most 7 ft. high,

very variable in habit, branches virgate or spreading, rigid

or tortuous, usually at first pubescent, occasionally glabrous,

_ bark dark brown or tawny. Leaves wide ovate or ovate-

elliptic or lanceolate-oblong, subacute, serrate, 1-14 in. long,

4-3 in. wide, glabrous cr more or less pubescent; petioles

thinly pubescent, 1-3 lin. long; stipules } in. long, subu-

late from a fimbriate base. lowers very tew, often only 2,

fteceptacle reddish, wide cylindric, narrowed in the middle

at the base. Sepals ovate, ciliate, under 1 lin. long. Petals

pale rose or white, obovate, about 24 lin. long. uit

ovoid, rather pointed, 3-5 lin. long, coloured as in our

figure when about to fall; in wild plants sometimes red,

The plant of Masdevallia pachyura here figured was

purchased for Kew at an auction sale in 1908, The

species is a member of the small group Amandae, with

racemose flowers and with the tube formed by the sepals

distinctly constricted below. It is a native of Ecuador,

where it was discovered by Roezl. It was first described by

Reichenbach in 1874. Its introduction to cultivation we

owe to the late Mr. Consul Lehmann, who sent plants to

Mr. J. O’Brien, with whom it flowered for the first time in

1897, Lehmann has noted that the range of this species is

somewhat restricted, it being confined to the western slopes

of Chimborazo, about one degree south of the Equator, at

elevations of from 5,600 to 8,300 feet above sea level. It _

is abundant around Cayandelet and above Pallatanga.

Usually found growing on trees in very damp thick woods,

it also occurs occasionally on walls of rock. As a rule it

flowers in the wild state in March and April; sometimes it

flowers again in November; the mean temperature of its

habitat ranges from 59° to 64° Fahrenheit. The plant

erows well and flowers freely under the treatment suitable

for most Masdevallias; a cool moist greenhouse, shade from

direct sunshine and a compost of sphagnum and peat. The

specimen from which our illustration has been derived

flowered in January.

Description.—HLerb, epiphytic, dwarf and tufted, without

pseudobulbs. Leaves clustered, spathulate-oblong, coriaceous,

recurved and rather acute at the tip, narrowed to the base,

3-4 in. long, 2-1 in. wide; petiole 2-3 in. long, with mem-

branous sheaths at the base. Scapes slender, erect, 6-9 in.

This handsome Rhododendron is one of the fruits of the

first journey in China made by Mr. E. H. Wilson on behalf

of Messrs. J. Veitch & Sons, and is the first of the large-

leaved, large-flowered, new Chinese species to blossom in

cultivation. Several of the smaller species of Rhododen-

dron, which cover considerable patches of open country

on the higher mountain slopes, as Calluna does in this

country, have already been figured in this work. The

large and broad-leaved species, of which R. sutchuenense Is

an example, oceur as a rule, Mr. Wilson informs us, 1n

partial shade and in association with other trees. Among

these larged-leaved species the one here figured has eo

unusual interest of flowering while it is of small size, an

Mancp, 1911.

the fine truss shown in our plate was borne by a plant, m

the Coombe Wood Nursery, which was less than 2 feet in

height. The flowers open early in March, so that they run

considerable risk of damage by frost. It will therefore be

advisable to select for this species, which otherwise is

hardy, a position shaded from the early morning sun. In

other respects its treatment should be that given to most

Rhododendrons. This species was originally described

from specimens collected in Szechuan. All those in the |

herbarium at Kew come, however, from Western Hupeh.

Description.— Shrub, 8-10 ft. high, free from scales and

nearly glabrous, flowering twigs straight, thick, occasionally

more or less tomentose at first. Leaves numerous, clustered

at the ends of the twigs, long-petioled, thick and leathery

when full grown, glabrous or sometimes tomentose on the

midrib beneath ; oblanceolate-oblong, from 3-10, but usually

about 6 in. long, narrowed to the base, usually rounded at

the tip, the uppermost smaller and occasionally acute, deep

green above, pale beneath ; midrib very stout, prominent

beneath; lateral main veins numerous and rather pro-

minent ; reticulation fine; petiole stout, occasionally almost

corky, 2-13 in. long. lowers densely corymbose, about

3 in. across, bud scales variable, silky ; corymbs almost

sessile, up to 8 in. wide; pedicels 3-3 in. long. Calyx

small or almost obsolete, faintly lobed, glabrous. Corolla

wide campanulate, with 5 broad rounded emarginate lobes,

rose-coloured and marked behind on the inside with darker

spots, puberulous towards the base. Stamens 13-15, decli-

nate, shorter than the corolla; filaments filiform, hairy

below the middle; anthers almost black. Ovary 12-locular,

glabrous, naked; style glabrous, declinate, hardly longer

than the stamens; stigma bright red. Capsule woody,

oblong, about 1 in. long, tipped by the hardened style.

The Primula here figured has been, since its independent

and almost simultaneous description by Regel and Hance

in 1874 and 1875 respectively, an object. of desire and a

subject for debate. The original specimens showed that

P, Mazximowiczii must prove a welcome addition to horti-

culture. The wish of more than five and thirty years’ stand-

ing has at last been fulfilled. The original specimens,

collected by Moellendorf, Bretschneider, Hancock and.

Potanin, all came from the province of Chihli in Northern

China, from the mountains in the neighbourhood of Peking.

The plants now, thanks to the efforts of Messrs. J. Veitc

& Sons, established in this country come from the same

province, but from a Jocality considerably further to the

Marcu, 1911.

north; they were obtained by Mr. W. Purdom in the

mountains of Northern Wei-chang, at about 9000 feet above

the sea. The species has also been recorded from Shansi by

Giraldi. The doubt connected with P. Maximowiezii has

had regard to the colour of the corolla. This, in all dried

specimens, is purple, and ‘ purple’ is the colour attributed

to the plant both by Regel and by Pax. Yet Hancock

found that his specimens, when fresh, had the corolla

‘intense crimson, and Potanin, an equally reliable

observer, found one plant with ‘red, another with

‘yellow’ corollas. Nor are our doubts even now at an

end. Our figure was prepared on 23rd March, 1910, from.

a plant sent to Kew from the Coombe Wood Nursery for

identification ; the colour, somewhat remarkable and unusual

in a Primula, accords with the experience of Hancock.

Yet, on the previous day, the Gardeners’ Chronicle states

(l.c. p. 221), a Certificate was awarded by the Royal Horti-

cultural Society to a plant of the same species shown by

Messrs. Veitch which had a ‘dark, clear purple’ corolla.

The nearest ally of P. Maximowiczii is a Primula from

Western Kansu, which Maximowicz considered to be no

more than a variety of our plant. Five years ago, however,

Duthie and Pax independently and simultaneously accorded

specific rank to this variety, as P. tangutica. Their species,

which appears always to have a ‘ dark purple’ corolla, has

been figured at t. 8043 of this work. It differs mainly

from the plant now described in haying longer calyx-teeth,

narrower corolla-lobes, and in the upper portion of the

scape being distinctly puberulous. P, Maximowiczii proves

to be perfectly hardy, and Messrs. Veiteh find that it thrives

best in a mixture of peat, loam and sand, in equal propor-

tions, and grows most satisfactorily when given a shady

position.

Description.—/fer), perennial, green, all parts except

the ciliate ealyx-lobes glabrous. Leaves all radical, narrow

The handsome Poppywort here figured has long been a

familiar plant in European alpine gardens. It is a native

of the high Himalayan Alps at from 12-16,000 feet above

sea-level and extends along the southern aspect of the

range from Central Nepal eastward to Bhutan; it also

crosses some, at least, of the passes leading northward to

the Tibetan table-land, and has been found at similar eleva-

tions in the provinces of Khamba and Phari in South Tibet.

In the section Polychaetia, characterised by the barbellate,

in place of smooth, hairs which constitute the indumentum,

M. simplicifolia is a member of the group Grandes, all the

species of which have divaricately radiating stigmatic lobes.

In two of these, M. integrifolia, Franch., figured at t. 8027,

and M. punicea, Maxim., figured at t. 8119 of this work, the

stigma is sessile; in the remaining species of the group

there is, as in our plant, a distinct style. Among these

M. simplicifolia most resembles M. quintuplinervia, Regel, a

native of North-western China, which, however, differs in

Marcu, 1911.

having but 4 petals, which are purple in colour. In habit

and general appearance our plant also agrees with WV. pseudo-

integrifolia, Prain, a yellow-flowered Tibetan species; as

regards its fruit it agrees with the Himalayan JZ. grandis,

Prain. First met with by Wallich in Nepal in 1819, it was

originally introduced to horticulture by Sir J. D. Hooker,

from Sikkim, in 1848. It has been repeatedly reintroduced

since, and the plant used in preparing our illustration

was raised from seed received in 1908 from the Royal

Botanic Garden, Calcutta. The seedlings were kept in a

cold frame until the spring of 1910, when they were planted

in a shaded moist position in the Rock Garden, where they

flowered in May, but failed to produce seeds. Less vigorous

in habit than some of the other species, I. simplicifolia

requires greater attention than most, especially when the

young seedlings, after they have produced two or three

true leaves, are pricked out into boxes or small pots. So

far as is known, M. simplicifolia is strictly monocarpic and

usually flowers in the second year. Occasionally, however,

at Edinburgh, where the climatic conditions enable this

species to thrive more satisfactorily than it does further

south, a few plants, Professor Bayley Balfour informs us,

defer flowering till their third season.

Descriprion.—/Terb, monocarpic, usually biennial; stem-

less. Leaves all radical, tufted, sparingly hirsute, ovate-

lanceolate, acute or somewhat obtuse, entire or distinctly

toothed, gradually narrowed downwards into a distinct

open flowers almost erect. Sepals 2, oblong-ovate, about

1 in. long, hirsute externally. Petals 6-8, ovate, clear blue,

2 in. long, about 1 in. wide. Stamens many, several-seriate ;

Clematis montana, Buch., is a somewhat polymorphic

species widely spread in the Himalaya and in the mountains

of Western and Central China. Ten distinct varieties have

been recognised by Briihl as occurring in Sikkim, Tibet

and Yunnan, though some of these depart so markedly

from typical C. montana that they might perhaps be just

as well treated as distinct species. The variety which

forms the subject of our plate is a native of China; our

figure has been made from a plant which flowered in July,

1909, in the Coombe Wood Nursery of Messrs. J. Veitch

& Sons, where it is known as the “autumn flowering

C. montana” ; it was obtained for them in Central China

by their collector, Mr. E. H. Wilson, whose name it bears.

It appears to be most nearly allied to a variety of

C. montana from Hupeh with pink flowers. But in addition

to having white in place of pink sepals, var. Wilsonii differs

from the variety rubens of our gardens in having the

sepals more oblong, with a more sharply marked glabrescent

Magcu, 1911.

median band outside, and in having less deeply cut leaflets.

It is not, however, at all certain that the Chinese var.

rubens, Hort., is the same as the original var. rubens,

Kuntze, which is based on a statement by Hooker and

Thomson that in the Himalaya the flowers of C. montana

are sometimes pinkish. Like other members of the genus,

C. montana, var. Wilsonii thrives in a rich loamy soil which

is all the better if of a calcareous nature. At Kew, where

no lime is actually present in the soil it is found very

advantageous to many species of Clematis if slaked lime

be added. Like the other varieties of C. montana, our

plant produces its flowers from the nodes of the previous

season’s growth; it should therefore only be pruned after

the flowers are past, and the shortening back of the shoots

during winter, so useful in the case of most species of

Clematis, must here be avoided. Propagation can be

readily effected by means of cuttings. The garden value

of this variety is enhanced by the fact that it flowers at

least two months later than the typical C. montana and

about six weeks later than var. rubens.

Description.—Shrub, climbing ; stems striate puberulous.

Leaves opposite, 3-foliolate; petioles 14-4 in. long, finely

sparingly puberulous; stalks of the end leaflet 2—1 in. long,

twice or thrice as long as those of the lateral leaflets ;

leaflets ovate narrowly acuminate, truncate or subcordate,

those of the flowering shoots elliptic and narrowed to the

base, 14-3 in. long, 1-1$ in. wide, wide serrate with

apiculate teeth; thin, glabrous above, puberulous on the

nerves beneath; nerves sunk above, raised beneath.

The remarkable Cirrhopetalum which forms the subject

of our plate is a native of Siam, where it was found,

near Panga, by Mr. Curtis, with whom it flowered in the

Botanic Garden at Penang in October, 1893. It was first

described, some three years later, by Mr. H. N. Ridley,

Director of the Singapore Botanic Garden. A plant of the

species was received at Kew from the Malay Peninsula in

1894. It would appear to be shy of flowering, for it has not

yet done so at Kew, though a plant in the collection at the

Royal Botanic Garden, Glasnevin, did so in July, 1903,

and another in that of Sir Trevor Lawrence, at Burford,

flowered in November, 1909. The figure of the inflores-

cence here depicted was prepared from Sir Trevor

Lawrence’s specimen sent for identification to Kew; that

of the leaves, pseudobulbs and rhizome has been taken from

Marcg, 1911.

the plant in the collection at Kew which agrees in every

detail with the Burford plant. The species thrives well

under the conditions suitable for other tropical species of

the genus; the circumstances which determine the forma-

tion of flowering spikes, however, remain obscure. When

these spikes do form, the plant becomes a striking object,

owing to the remarkable length of the lateral sepals, which

in the wild state and in flowers developed in the open air in

the Malay Peninsula are stated by Mr. Ridley to be upwards

of a foot in length, and readily distinguish it from every

hitherto described species.

Description.—Lerb, epiphytic; rhizome creeping, rather

stout; internodes 14-24 in. long; pseudobulbs ovoid,

1-1} in. long, clothed at the base with ovate membranous

sheaths, each bearing a single leaf. Leaves subsessile,

oblong, leathery, recurved and subacute at the tip, narrowed

to the base, 34-6 in. long, 1-13 in. wide. Scapes curved or

pendulous, about 8 in. long, beset with 2-3 acuminate

sheaths. Flowers in umbels of 4-7, shortly pedicelled,

whitish with rose-coloured streaks, bracts oblong-lanceolate,

acuminate, 5-7 lin. long, about as long as the pedicels.

Sepals: posterior lanceolate or oblong-lanceolate, ciliate,

3-? in. long, incurved, concave, marked with 5 red longi-

tudinal veins; lateral pair long connate, linear, 8-12 in.

long, with distinct pink longitudinal streaks, and ending in

very long slender tails. Petals falcate, oblong or oblong-

lanceolate, somewhat acute, ciliate, 4-5 lin. long. Lip re-

curved, ovate-oblong, subacute, fleshy, channelled along the

centre, about 4 lin. long. Column oblong, about 4 lin.

long; stelidia faleately incurved, filiform, acute; anther

shortly hispid.

Clematis aristata, R. Br., to which the form here figured

is referred, is a native of Australia. The species was

originally based on specimens from New South Wales,

but in the Flora Australiensis a somewhat comprehensive

view was adopted by the late Mr. Bentham, who attributes

to C. aristata a wide distribution, and assigns to it several

varieties. It is now, however, generally believed that the

variety coriacea of that work includes at least the typical

C. aristata and C. coriacea, DC., that the variety blanda is

the distinct Tasmanian C. blanda, Hook., and that the

variety occidentalis is the equally distinct Western Aus-

tralian C. pubescens, Hueg. Some authorities, on the other

hand, have treated as distinct certain forms that are usually

referred to typical C. aristata, and in the case of the subject

APRIL, 1911,

of our illustration, the plea for separate treatment is un-

usually strong. The plant here depicted differs markedly

from true C. aristata in the longer coarsely dentate-serrate

leaflets, and in this respect agrees more closely with certain

specimens from New South Wales in the Kew herbarium

which may be referable to C. coriacea, DC. These New

South Wales specimens, however, which do not agree with

typical C. aristata, differ also from our plant, which is a

native of Victoria, in having considerably longer append-

ages to the anthers. Specimens of what we believe to be

the female state of our plant were first collected by the late

Baron von Mueller on Mount Disappointment and in the

Delatite valley nearly sixty years ago; the notes attached

to these specimens show that von Mueller originally con-

sidered the plant entitled to specific rank. More than

half a century was to elapse before the plant attracted in

Australia the notice that it deserves, for it was not, till

about 1904 that it was introduced to cultivation by Mrs. J.

Dennis, of Murngal, who had met with it on the Healesville

ranges in Evelyn. Mr. W. R. Guilfoyle, Director of the

Melbourne Botanic Gardens, on receiving examples, marked

his sense of the position of the form and of the merit of its

discoverer by naming it in her honour. Under this name,

already familiar in Australian gardens, Mr. Guilfoyle, early

in 1907, forwarded living examples to Messrs. I. Sander

& Sons, in whose nursery at St. Albans our plant flowered

in May, 1907, for the first time in Europe. This introduc-

tion was noted at the time in the Gardeners’ Chronicle ;

the writer of that note, while unaware of the history of

the plant, independently formed the opinion at which Baron

von Mueller had arrived in 1852, Later in the same year

Messrs. Sander presented a living plant to the Kew col-

lection. This plant, from which the material for our figure

has been derived, has thriven well in a sunny greenhouse

under the conditions suitable for C. indivisa, Willd., figured

at t. 4398 of this work, which it resembles in habit and in

being evergreen. It blossoms in May, and the flowers,

which are fragrant, are striking on account of the salmon-

red colour of their filaments. This character has not been

ascribed to any of the forms hitherto referred to C. aristata,

nor do the specimens of those at our disposal indicate its

existence. Having regard, however, to the incertitude

attending negative evidence it appears desirable, until

further field observation has been made, to follow Mr.

Guilfoyle in treating this striking plant as a well-marked

variety of C. aristata.

The handsome Acanthad which forms the subject of our

plate has been figured from a plant which flowered in the

collection at Kew in May, 1910. This plant, which was

sent by Mr. H. N. Ridley from the Singapore Botanic

Arnit, 1911.

Garden in 1908, was accompanied by the remark that it is

the true Eranthemum malaccense, Clarke, a species which

appears to be confined to the Malayan Peninsula, where it

extends from Langkawi in Kedah southwards to Johor.

The plant is, as Mr. Ridley indicates, E. malaccense; the

identification is important because, in a valuable annotated

list of cultivated Acanthaceae by Col. R. H. Beddome,

published in the Journal of the Royal Horticultural Society

in 1908, E. malaccense, Clarke, has been treated as identical

with E. graciliflorum, Nees. Some doubt has arisen as to

the precise limitation of LE. malaccense, and more than one

species has been included under that name, but, for reasons

which have been discussed in a recent number of the Kew

Bulletin (1911, p. 79), and need not be detailed here,

Dr. Stapf has found himself unable to adopt the view that

the true E. malaccense, here figured, is undoubtedly refer-

able to £. graciliflorum. Our plant, however, is not a

member of the tribe Ruellizae, and therefore is not an

Eranthemum ; it belongs to the tribe Justicieae, and is a

member of the genus Pseuderanthemum, the species of

which, owing to a misapprehension explained at t. 8239 of

this work, are still at times supposed to be Eranthemums.

On this account the name given to this species by Dr.

Lindau must be adopted; another species, P. seticalyz,

Stapf, from Tropical Africa, has already been figured at

t. 8244 of this Magazine. P. malaccense grows freely in

a stove and forms a bush about 3 feet in height. Like

many tropical Acanthads it is most satisfactorily cultivated

when raised annually from cuttings, and requires to be

liberally treated as regards soil and moisture.

Descriprion.—Shrub; 3-5 ft. high, branches terete,

somewhat scabrid with small rigid upeurved somewhat

adpressed hairs, Leaves lanceolate or elliptic-lanceolate,

narrowed to base and tip or often acuminate, 3-5 in. long,

#-2 in. wide, thin, slightly scabrid, finely hairy along the

midrib above and below, lateral veins about 7 on each side,

oblique, curving throughout; petiole slender, 1—3 in. long.

Inflorescence simply branched, $—-2 in. long, sometimes with

one or more basal branches, scaberulous everywhere like

the twigs, flowers numerous, many opening together, at

first in few-flowered whorls or opposite or occasionally

scattered, the very lowest often rudimentary, at length

more or less drawn out above in a raceme; bracts lanceo-

late or lanceolate-subulate, about 1 lin. long, spreading ;

bracteoles like the bracts, but rather wider and _ shorter ;

pedicels about 1 lin. long, oblique and erect or ascending

from a spreading base. Calya deeply divided, barely 1 lin.

long, lobes subulate. Corolla hy pocrateriform ; tube narrow,

nearly straight, 1-14 in. long, pale violet, finely sparingly

glandular outside; limb pale violet or violet-white, with

red specks on mid-lobe of lower lip, about ? in. across, lips

spreading, their lobes wide oblong, the 2 upper more

distinctly connate than the 3 Jower, of which the median is

} in. wide, sparingly hairy in the centre. Anthers short

elliptic, as long as their filaments, the connective somewhat

glandular. Ovary glabrous, surrounded by the annular

disk; style faintly hairy below. Capsule unknown.

The genus Elaeagnus, which includes about twenty-five

species, mostly natives of South-Eastern Asia, is represented

in North America by the solitary species here figured,

which extends from Utah to the Upper Missouri and

thence eastward to Minnesota and Canada. Two other

species, both natives of Japan, have already been figured

in this work; EF. multiflora, Thunb., at t. 7341, and £.

macrophylla, Thunb., at t. 7638. Like the other species of

the genus, /. argentea is characterised by the close lepidote

indumentum to which it owes the popular name Silver

Berry by which it is known in the United States and

Canada, and among hardy shrubs whose Jeaves have this

grey metallic lustre the present plant is perhaps the most

striking. There are others of the same shade, but they

mostly are of dull surface, and lack the peculiar metallic

sheen characteristic of this species. It also flowers freely,

and its clear yellow blossoms contrast admirably with the

Apnriz, 1911,

foliage. EL argentea is occasionally grown and sold in

nurseries as Shepherdia argentea, but the true S. argentea,

Nutt., known popularly in the United States as the Buffalo

Berry, though similarly silvery lepidote, is at once dis-

tinguished from our plant by its opposite Jeaves. The

lant from which our figure has been prepared has long

cs. in cultivation at Kew, where it forms a desirable shrub

and is quite hardy. It is readily propagated by means of

suckers which are freely produced.

DescripTion.—Shrud ; reaching a height of 14 ft., freely.

branched ; bark brown, lepidote. Leaves alternate, petioled,

lanceolate or elliptic-lancevlate, acute or obtnse, base cuneate

or rounded, lepidote and with a faint metallic sheen above,

The pleasing Composite here figured was originally met

with by Mr. T. Cooper in 1861, in Basutoland and in the

Albert Division of Cape Colony, where it was found

hanging over precipitous rocks, It appears never to have

been collected again until 1903, when Mr. Dieterlin sent

from Basutoland to the Botanic Garden, Montpellier, a

herbarium specimen and some ripe achenes, thus effecting

its introduction to European gardens. Several species of

the genus Fvlicia have already been figured in this work :

£, tenella, DC., as an Aster, at t. 33; F. refleca, DC., also

as an Aster, at t. 884; and /” echinata, DC., at t. 8049.

Like the last-mentioned species, J’, petiolata is a shrub of

loose straggling habit, and therefore under cultivation it

requires to be cut back frequently during the season of

Aprin, 1911,

growth. Its nearest ally in the genus appears to be

F. Cymbalariae, Schlechter (Aster Cymbalariae, A7t.), but

it is readily distinguished, among other characters, by the

alternate leaves and the much larger ray-florets. The

plant has to be grown under greenhouse conditions and its

cultivation is unattended by difficulty. In the Kew col-

lection it flowers about midsummer; the plant from which

our figure has been prepared flowered early in June, 1910,

in the collection of Mr. W. E. Ledger, Wimbledon, by

whom it was sent for identification.

The very remarkable Dendrobium which forms the subject

of this plate is a native of New Caledonia first described by

Mr. Finet in 1903. In reviewing its position in the genus

Mr. Finet has suggested that it may belong to the section

Dendrocoryne and be an ally of D. speciosum, Smith, figured

at t. 3074 of this work. The difficulties in the way of

accepting this suggestion are considerable, and Mr. Rolfe,

who points out that the vegetative organs, as shown in the

plant here figured, have probably not yet reached their full

development, is inclined to treat it rather as an aberrant

member of the section Sarcopodium. The form regarded as

typical D. muricatum differs markedly from the variety here

depicted in the shape of the lip, especially in the widely

hastate-cordate anterior lobe. ‘The muricate roots character-

istic of the species are remarkable and recall those of

D. mutabile, Lindl. The plant from which our figure has

been prepared flowered in the Royal Botanic Garden,

ApriL, 1911. :

Glasnevin, in August, 1909. Mr. Moore, to whom we are

indebted for the material, informs us that this plant, con-

sisting then of two fair-sized pseudobulbs, was presented by

Dr. R. Schlechter to the Irish national collection in

September, 1906, and was stated to have come direct from

New Caledonia. In 1907 it made but weak growth, in

1908 a slightly stronger growth, and in 1909 a vigorous

fresh growth, about two-thirds the size of the imported

pseudobulb, was perfected and produced the inflorescence _

shown in our figure. The hard, firm nature of the pseudo-

bulbs and the thick coriaceous leaves indicate that it is a

light-loving species. At Glasnevin, Mr. Moore bas grown

it in a pan suspended near the glass in the intermediate

orchid-house where it gets abundant light and a fair supply

of air. In this position, potted in a mixture of Osmunda

fibre and fibrous peat, with some broken crocks and a little

fresh sphagnum worked through, the plant thrives well.

DescriptTion.—JLerb ; epiphytic ; rootstock stout, giving

out muricate roots. Pseudobulbs ovoid-oblong, 13-24 in.

long, about 1 in. thick, clothed with membranous striate

imbricate sheaths which ultimately are reduced to hispid

shreds or disappear, leaving the pseudobulb marked by

5-7 annular scars. Leaves 1-2, terminal, elliptic-oblong,

leathery, recurved and somewhat pointed at the tip, «

narrowed downwards into a short petiole, 3-9 in. long, |

1}-23 in. wide. Scapes almost terminal, curved, 8-16 in.

many-flowered ; bracts triangular, acute, 1 lin. long;

pedicels 3 in. long. Sepals spreading, oblong, apiculate,

about 2 in. long, greenish and with brown blotches. Petals

mucronulo, basi rotundata vel subcuneata, supra glabra, subtus densissime

The handsome Rhododendron here figured is one of a

number of species raised in the Jardin des Plantes from

seeds sent to Paris by the late Abbé Delavay. A set of

these plants was presented to Kew in 1888, and the first

to flower was LR. scabrifolium, Franch., figured at t. 7159

of this work in 1891, followed by R. racemosum, Franch.,

figured at t. 7301 in 1893, and by &. irroratum, Franch.,

given at t. 7361 in 1894. These three are comparatively

small shrubs which mature early, and it was not till 1904

that another member of the set, R. Delavayi, Franch.,

similar in habit to the well-known &. arboreum, Sm.,

May, 1911.

flowered for the first time in the garden of the late

Mr. Acton, at Kilmacurragh, Wicklow; it was figured in

1907 at t. 8137 of this work. The species here described

has postponed flowering for even a longer period, for it was

not till 1908 that it first blossomed in the garden of

Mr. P. L.de Vilmorin, at Verriéres-le-Buisson. It has now to

be recorded as having flowered in this country in the garden

of Mr. F. D. Godman, at South Lodge, Horsham, where a

collection of Rhododendrons has been, for many years,

cultivated with exceptional skill and success. From this

plant, a large and hardy bush, which blossomed for the

first time in April, 1910, was obtained the material from

which our illustration has been prepared. It may be men-

tioned that there is an equally fine example of R. lacteum at

Kilmacurragh, of the same age as the South Lodge plant,

but that there is as yet no record of its having flowered.

In this feature of not flowering until it is about 20 years

old #. lacteum resembles its nearest ally, R. Fulconeri,

Hook. f., figured at t. 4924 of this Magazine, and there is

every indication that it may grow to as large a size as

f. Faleoneri and &. grande, Wight, attain in the warmer

parts of Britain, and that it may prove fully as hardy as

these species. It should be noted that another species of

Rhododendron, from Borneo, first described in 1894, has

been given the same name. For this latter plant, R. lacteum,

Mr. Hemsley proposes to substitute the name &. Stapfianum,

The genus Deinanthe was based by Maximowicz in 1867

on a plant which grows in shady woods in Southern Japan.

It has been figured in the Somoku Zusetz under the name

Guin bai sd, and according to Franchet and Savatier may

occasionally be met with in Japanese gardens. The Japanese —

species D, bifida, Maxim, does not extend beyond Japan,

but the genus is represented in China by another which 1s =

May, 1911. : oe

here figured. This Chinese species, when first sent to

Europe by Mr. A. Henry, who discovered it at Hingshan in

Hupeh, was identified from his specimens with the Japanese

plant. They are indeed closely allied, but now that living

plants are known it is evident that they are very distinct.

The introduction of D. caerulea to cultivation we owe to

Mr. E. H. Wilson, who rediscovered the plant at Nant‘o in

Hupeh, where it grows in wet places on cliffs, when collect-

ing on behalf of Professor Sargent of the Arnold Arboretum.

From some of the seeds then obtained plants were raised by

Mr. H. J. Elwes in his garden at Colesborne, Cheltenham,

where the species flowered for the first time in this country

in Ancust, 1909. One of the Colesborne plants, presented

by Mr. Elwes to Mr. Dimsdale, of Ravenshill, Lechlade,

flowered there in May, 1910, and provided the material

from which our figure has been made. Material from

another and much more robust plant, which flowered at

Colesborne in August, 1910, was subsequently communicated

by Mr. Elwes, who informs us the plant evidently prefers a

very shady and moist situation, specimens put out under a

north wall growing much more vigorously than those kept

in pots. At Colesborne it has all the appearance of being

a hardy plant. Mr. Elwes has directed our attention to the

fashion in which the corolla separates from the receptacle

when the flower is only two or three days old. In a note

on the specimens obtained by him at Nant’o Mr. Wilson

states that the flowers are white to purple; apparently only

blue flowers have as yet been produced in cultivated plants.

In the Japanese D. bisida, the petals appear always to be

creamy-white or pure white with yellow stamens.

The remarkble Oncidium which torms the subject of our

plate is a very interesting addition to the small group of

species known as Butterfly Orchids hitherto believed to

consist of but two species, viz. :—O. Papilio, Lindl., figured

at t.2795 of this work, which isa native of Trinidad and the

adjacent coast of Venezuela, and O. Kramerianum, Reich. f.,

which occurs in Colombia and Ecuador. This new member

of the section is a native of Peru, where it was obtained in

the Moyobamba district by Mr. Forget, when collecting

on behalf of Messrs. F. Sander & Sons, by whom it was

imported in 1909. It flowered in the firm’s nursery at

St. Albans in August, 1910, and from their plant was

received the material on which our figure is based. The

three species of which this group is composed bear a close

resemblance to each other in habit and in the handsome

marbling of their leaves. It is interesting to note that

although geographically more remote from O. Papilio than

from VO. Kramerianum, it is to O. Papilio that O. Sanderae

is most close] y allied, the upper portion of the inflorescence

May, 1911.

being somewhat flattened; O. Avamerianum is readily

distinguished from both by its nodose inflorescence.

O. Sanderae is, however, readily distinguished from

OQ. Papilio by the much crisped lateral petals and lip, by

the lighter coloration of the flowers, and by the numerous

elandular appendages on the wings of the column, There

is every indication that under cultivation O. Sanderae will

thrive under the conditions as to heat, light and moisture

that are suitable for its two near allies.

The handsome Honeysuckle which forms the subject of

our plate was introduced to cultivation by Mr. EB. H. Wilson,

who obtained it, when collecting on behalf of the Arnold

Arboretum, in the province of Hupeb, where it had pre-

viously been met with by Mr. A. Henry, whose specimens

formed the basis of its original description. It is, however,

now known to occur also in the provinces of Szechuan and

Yunnan. The species belongs to the section Nintooa,

another species of which, L. Giraldii, Rehder, has already

been figured at t. 8236 of this work. But though nearly

allied and members of the same natural group, these two

are readily distinguished, because the leaves of L. Henryi

are glabrous except on the midrib, whereas those of

L. Givaldii ave pilose on both surfaces. £. S/enryi has

been in cultivation in this country at Kew, and in some

May, 1911.

other collections, for rather less than three years, and the

first plant to flower in England is one at Nuneham in the

garden of the Right Hon. L. Harcourt, to whom we are

indebted for the material on which our illustration is based.

A free-growing climber which promises to be hardy,

L. Henry is very easily propagated by means of cuitings

made of half-ripened shoots taken about the end of July

and placed in gentle bottom heat. The fact that the species

is evergreen gives it a particular value in gardens, for in

spite of the quite extraordinary number of hardy woody

plants that have been introduced during the last decade,

true evergreen climbers, as distinguished from the bushy

shrubs made to do duty as such on garden walls, form still

but a small group. This is largely due to the fact that

evergreen climbers represent a type of vegetation more

characteristic of tropical and subtropical than of the cool

temperate zones ; any accession to their numbers which is

likely to thrive in our climate is therefore welcome.

Descriprion.—Shrub; climbing ; twigs slender, at first

densely tawny-pubescent, at length almost glabrous; bark

reddish-brown. Leaves oblong-lanceolate, acutely acumi-

mate, base rounded, truncate or slightly cordate, 13—23 in.

Journ. vol. xiii. Oct. 1882, p. 243.—T. A. SpRaGur.

The commemorative name Villaresia was originally

bestowed by Ruiz and Pavon on a Peruvian plant collected

at Pillao; a description of this genus was given by them in

1794 (Fl. Per. et Chil. Prodr. p. 35), and an account of

UZ emarginata, the species on which it was based, was

supplied in 1798 (Syst. Veg. FI. Per. et Chil. p. 64). The

Specimens of this Peruvian plant would appear to have been

lost ; possibly, as D, Don has suggested, in the shipwreck of

the San Pedro de Alcantara. But from the descriptions

Which exist we learn that V. emarginata had a. sessile

stigma, an oblong acuminate 2-valved, l-seeded capsule, and

May, 1911.

an oblong tetragonal sced surrounded by a fleshy 2-lobed

arillus. It has hitherto proved impossible to identify V.

emarginata with any Peruvian plant collected since 1t was

described, but it is obvious that it is a member of a genus

very different from that to which the plant with a distinct

style and a drupaceous fruit here figured belongs.

Specimens of our plant, V. mucronata, collected at Con-

cepcion in Chile, were made the basis of a second and different

Villaresia by the same authors in 1802 (FI. Per. et Chil.

vol. iii. p. 8), and although D. Don in 1832, realizing the

situation, proposed to substitute for the Chilian Villaresia

the name Citronella, his suggestion has not been adopted,

subsequent authors preferring to apply the name proposed

by Ruiz and Pavon to the Chilian V. mucronata and its

allies. The material on which the figure of V. mucronata

here given has been based was derived from a fine example

in the garden of the Right Hon. the Earl of Ilchester at

Abbotsbury, where it forms a tree between 50 and 60 ft.

high, of pyramidal habit, but somewhat drawn up by other

trees. It may be remarked that Miers stated that this

species, which is the ‘ Naranjillo’ of Aconcagua, had been

described in the Viceroy’s report to His Majesty the King

of Spain as from 50 to 60 ft. high, but that he (Miers) had

never seen or heard of its attaining any approach to that

size. The species is only hardy in the south-west of England

and in other parts of the United Kingdom with a similar

climate. The upper portion of the tree has leaves which

are devoid of spines, but on young trees and on suckers

from old trees the leaves are spinescent-toothed, and the

plant described as V. pungens by Miers is only this state of

V. mucronata. The only mode of increase in this country

is by means of cuttings, but these, unfortunately, do not root

readily. The tree at Abbotsbury was introduced to the

collection there about 1840 by the Hon. W. Fox-Strangways

—-whose name is commemorated in the genus Stranvaesia,

one of the most ardent horticulturists of his day. :

Drscriprion.— Tree ; usually 40 ft. or less, rarely 50-60 ft.

in height; twigs angular, at first pubescent, ultimately

nearly glabrous. Leaves alternate, short petioled, ovate- or

elliptic-oblong, in old trees with a spinulous tip and an

obtuse or rounded base, 2-3 in. long, 1-13 in. wide, entire ;

in young specimens and on suckers from the base larger,

with a rounded or subcordate base and an undulate promi-

nently spinulous-toothed margin ; leathery, slightly convex,

dark green, shining above, paler and dull beneath, nerves

raised beneath, often with solitary pits at their angles;

petiole 13-23 in. long. lowers 5-merous, in solitary

shortly pubescent thyrses, terminal or in the upper axils,

1-2 in. long; their branches spreading, with several sessile

flowers at their tips. Sepals suberect, imbricate, wide

elliptic or nearly orbicular, 1 lin. long or less, sparingly

ciliate and pilose outside near the base. Petals yellowish-

white, elliptic-oblong, rounded at the tip, 3 lin. long,

i lin. wide, the midrib thickened and prominent on the

inner face. /ilaments rather stout subulate, shortly adnate

below to the petals, 1-14 lin. long; anthers wide elliptic,

opening laterally. Ovary by abortion 1-celled, ovoid,

under I lin. long; style straight, 3 lin. long; stigma

oblique, irregularly lobed; ovules 2, collateral, pendulous.

This handsome Cattleya was originally discovered by

Mr. Bungeroth on the western slopes of the Peruvian Andes,

and was introduced to cultivation by Mr. L. Linden,

L’Horticulture Internationale, Brussels, in which estab-

lishment it flowered for the first time in 1890; in the Kew

collection it flowered for the first time in 1893. The plants

of this earliest importation did not as a rule survive many

years, and the species had become very rare in cultivation

when Messrs. Sander & Sons, St. Albans, a year ago

succeeded in obtaining a fresh consignment of plants from

Mayobambo, in the Upper Amazon region. One of these

plants, purchased for the Kew collection, flowered in a

tropical house in July, 1910, and afforded the material from

which our plate has been prepared. The species may be

regarded as most nearly allied to C. maxima, Lindl, ; it

JuNE, 1911.

differs, however, in having ivory-white in place of hght

purple sepals and petals, and in the different shape and

markings of the lip, which has also yellow side-lobes. It is

said that sometimes.as many as nine or ten flowers may be

counted on the old racemes of newly imported plants.

Experience indicates that tropical conditions are most

suitable for this Cattl-ya, the healthiest examples being

those grown along with C. aurea and C. Lawrenciana in a

warm moist house where they receive a fair amount of

sunshine in summer.

The Columnea which forms the subject of our illustration

is perhaps the most handsome of the species yet introduced to

cultivation. The plant from which the material for our figure

has been obtained was purchased for the Kew collection in

1909 from Messrs. Haage & Schmidt, of Erfurt, who are

well known on account of the large number of uncommon

and interesting plants which they cultivate. A native of

Costa Rica, C. gloriosa belongs to the section Eucolumnea,

June, 1911.

- marked by the strongly 2-lipped corolla with the lateral

lobes more or less adnate to the hood and by the solitary

posticous disk-gland. Our plant may be readily distinguished

from the other species in cultivation by its spreading calyx

and its convex, hairy, reddish leaves with much reflexed

margins; the sepals resemble miniature leaves. It also

differs in its prostrate habit and in the exceptional size and

brightness of its flowers. Seven other Columneas of the

same section have already found a place in this work.

The finest of these is C. magnijica, Kl. & Hanst., a native

of Central America, fignred in t. 8225. Allied to C. mag-

nifica are three West Indian species: C. rotundifolia, Salisb.,

figured as “©. scandens” in t. 1614; the true C. scandens,

Linn,, t. 5118; and C. hirsuta, Sw., t. 3081. A_ pretty

little plant with small ovate or ovate-oblong glabrous

leaves is C. Oerstediana, Kl., from Costa Rica, figured in

t. 8344; and C. Schiedeana, Schlecht., from Mexico, given

in t. 4045, is remarkable for the colour of its flowers, the

calyx being brick-red, aud the corolla yellow with red spots.

Lastly C. crassifolia, Hook., also Mexican, figured in t. 4330,

is striking on account of its long, suberect, linear-lanceolate

leaves. <A comparison of the figures to which reference

has been made will show that some of the best diagnostic

characters are afforded by the shape and indumentum of

the leaves and by the nature of the calyx. At Kew C.

gloriosa is cultivated in a basket suspended from the roof;

the long pendent shoots, which retain their leaves through-

out the year, produce flowers freely during the summer.

The plant requires tropical conditions with abundant

moisture and shade from bright sunshine.

The interesting plant here figured was presented to Kew

by Mr. T. A. Dorrien Smith of Tresco Abbey, Isles of Scilly,

in 1908, under the name Prostanthera phylicifolia. Its

introduction to English gardens we owe to Captain A. A.

Dorrien Smith, who informs us that, so far as he can recollect,

he obtained it from Messrs, Naian, nurserymen of Christ-

church, New Zealand. That the plant is a Prostanthera

will be very evident if our illustration be compared with

the figure of P. denticulata, R. Br., given in t. 7934 of this

work. Yet in spite of the general similarity of these two

plants it will be noticed that they differ very markedly, for

P. denticulata has setose leaves and is quite unlike our

plant as regards calyx, corolla and anthers. Two other

Jonm, 1911.

species which agree with our plant in habit and in having

narrow leaves are P. linearis, R. Br., and P. empetrifolia,

Sieb., the latter figured in t. 3405 of this work under the

name Chilodia scutellarioides ; both of these, however, have

a distinctly two-lipped corolla, the upper lip being much

the shorter, and are therefore very different from the

species here figured. With the true P. phylicifolia, F.

Muell., for which our plant is apparently mistaken in New

Zealand, it has little in common, for P. phylicifolia is much

more woody, its leaves are broader, shorter and conspicu-

ously revolute, its corolla is altogether different, and its

anthers are appendaged. The genus Prostanthera, which

includes over fifty species, is restricted to Australia, the

eastern ‘portion of the continent being the home of the

majority. Many of these species were formerly cultivated

in this country as greenhouse plants together with other

showy Australian species. Now they are hardly known

outside the limits of botanical collections. But the one

here figured, now introduced by way of New Zealand, is

not one of these, nor indeed is it one that has ever been

previously described. In Baron von Mueller’s Second

Census of Australian Plants, where forty-four species are

enumerated, twenty-eight are recorded from New South

Wales, eighteen from Victoria, thirteen each from Queens-

land and South Australia, seven from Western Australia

and three from Tasmania; several of the species are

common to two or more of these states. We have so far

failed to ascertain from which of these subordinate areas

P. pulchella may have found its way to New Zealand,

while it is almost as difficult to suggest where it should be

placed within the genus to which it belongs. In the Flora

Australiensis the species are disposed in two sections. In

one of these, Euprostanthera, the corolla tube is short and

wide, the upper lip is short, very broad and erect, the lower

lip is much longer and spreading, while the lips of the

calyx are usually closed over the fruit. In the other,

Klanderia, the corolla tube is incurved and dilated upwards,

the upper lip is erect and concave and is as long as or

longer than the spreading lower lip, while in fruit the lips of

the calyx usually remain open. <A third section, Depresme-

nilia, has been added in the Natiirlichen Pflanzenfamilien ;

the most salient feature of this is that the calyx is shortly

bia

pee

5-toothed. P. pulechella, in which the calyx has two

entire or emarginate lips, cannot be referred to the last

section. If it must be placed in one or other of the

remaining sections it is to Huprostanthera rather than to

Klanderia that it should be referred, but it does not by any

means satisfactorily accord with the characters exhibited

by the other species of the section. In the gardens of

Tresco Abbey P. pulchella forms a shrub which thrives

well in the open and flowers freely in April. At Kew it

is cultivated in the Temperate House, where it grows

satisfactorily when planted in sandy peat and given the

treatment suitable for species of Boronia and other Austra-

lian genera.

Descriprion.— Undershrub; about 14 ft. high, of graceful

habit and freely flowering ; twigs spreading, sparingly

finely adpressed puberulous. Leaves subsessile, linear or

linear-lanceolate, 13 in. long, 1 lin. wide, obtuse or rounded,

entire, almost glabrous, sparingly gland-dotted. Mowers in

lax erect rather strict 10—18-flowered racemes, 2-3 in. long ;

bracts like the leaves but smaller, as long as or rather

longer than the 1-2 lin. long pedicels which are adpressed

grey-puberulous and 2-bracteolate at the tip. Calyc about

24 lin. long, sparingly finely puberulous and glandular out-

side, densely puberulous near the top within, lips entire or

emarginate, the upper rather shorter than the lower, remain-

ing open after flowering. Corolla subrotate, faintly 2-lipped,

lilac, the tube white at the base, the throat with dark purple

dots; tube about 2 lin. long, narrow at the base; limb

8 lin. wide; upper lip 2-lobed, slightly arched, 24-3 lin.

long, 43 lin. wide, lobes obovate, 2 lin. long and about as

wide, faintly imbricate and crenulate ; lower lip spreading,

3 lin. long, lobes oblong or elliptic, 25 lin. long, about 2 lin.

wide, crenulate. Stamens didynamous, the larger pair

barely reaching the middle of the corolla; anthers puberu-

lous and without appendages. Nutlets obovoid, glabrous,

foveolate.

The genus Pteronia, to which the subject of our illustra-

tion belongs, includes upwards of sixty species of small dry

or glutinous South African shrubs. The species here figured,

P. incana, has a wide range within the area occupied by

the genus, and extends from Lesser Namaqualand in the

north-west to the Albany district in the south-east. Its

nearest ally is P. glauca, Thunb., from which our plant is

readily distinguished by its flat and usually longer leaves

and by its narrower glabrous involucral bracts which have

hyaline margins. This, the first species of the genus to be

figured in this work, for the plant figured at t. 1697 as

P. pawiflora is a Helipterum, is a favourite in Riviera

gardens, where it flowers freely from March till May and

forms a bush some three feet high, which is attractive alike

for its wealth of blossom and its remarkably sweet peach-

Jong, 1911,

like odour. The material from which onr figure has been

prepared came from the garden of Lady Hanbury at

La Mortola, Ventimiglia, to which the species was first

introduced by the late Mr. D. Hanbury in June, 1872. At

Kew the plant thrives well under the conditions suitable for

South African heaths, but it does not flower at all freely,

probably owing to the absence of sufficient sunshine during

the winter months,

The Composite genus Saussurea, including some seventy

species, is characteristic of the mountainous and temperate

regions of the northern hemisphere. The striking plant

here figured belongs to a well-defined group of species

characterised by the flower-heads being more or less

enclosed in the inflated, bladderlike, membranous, veined

bracts or uppermost leaves, which differ in coloration as

well as in texture from the leaves proper. This group

has its headquarters in the Alpine regions of India and

China, and the species now figured is one of the many

interesting plants from the Chinese portion of this area for

whose introduction horticulture is indebted to Mr. E. H.

Wilson when collecting on behalf of Messrs. J. Veitch &

Sons. The seeds of this species were obtained at Fung in

Jung, 1911.

Central China and reached Messrs. Veitch towards the’ end

of 1901. Plants were raised in 1902, and from one of these,

presented by Messrs. Veitch to the Royal Botanic Garden,

Glasnevin, in December, 1904, came the material from which

our plate has been prepared, Planted in a good border

and protected by a wall facing south-east, S. Veitchiana,

Mr. Moore informs us, has proved perfectly hardy at Glas-

nevin. The soil which has been found suitable is a light

loam, fairly deep and well-manured. The plant, to which the

dark flowers impart a very remarkable appearance, flowered

for the first time in 1909 and again more strongly in 1910.

As Mr. Drummond points out, the species though nearly

related to the others which constitute the ‘ bracteate’

group is nevertheless readily distinguishable from most of

them. Its closest ally is the as yet little-known S, iodostegia,

so named on account of its violet-tinted floral leaves,

described by the late Dr. Hance from specimens collected

on Siao Wu-tai-shan by Mr. Hancock so long ago as 1876.

Desoription.— Herb, 2-3 ft. high, with about 2-5 leafy

scapes from a tufted crown; flowering stems erect, rigid,

floccose upward, grooved, leafy. Leaves green above with

a pale stout midrib, loosely hairy beneath, those lowest

Viburnum rhytidophyllum is one of the most remarkable

shrubs which the recent exploration of Western China has

given to gardens. It is perfectly evergreen, but of a type

very distinct from any evergreen species in the genus,

resembling more, in its excessively wrinkled leaves, the

species of the “ Lantana” group. It is, however, absolutely

different from those or any other Viburnum, and is, indeed,

one of the best-marked of all shrubs in cultivation. —

Introduced by Mr. E. H. Wilson for Messrs. Veitch in 1900,

it has withstood, without any injury, all the frosts of the

last decade. The plant from which our figure was prepared

was purchased in 1906, and is growing against a south

wall, [t does not need such protection as that position

gives, but, so far at any rate, has flowered and borne fruit

Juxy, 1911.

more freely there than in the open. It forms its inflorescence

and partially develops it in autumn, but the flowers do not

expand until the following May. They are of a dull

yellowish white and not particularly ornamental. The

fruits turn red in September, and the plant then acquires

its greatest beauty; finally the fruits turn black.

V. rhytidophyllum requires a rich loamy soil and appears

to thrive anywhere except on a bleak, wind-swept spot.

It can be increased easily by means of cuttings made of the

summer growths about the end of July, and placed in pots

of sandy soil in a slightly heated, close frame.

Descriprion.—Shrub or small tree; young shoots tomen-

tose; flowering twigs stout, rigid, straight, their internodes

much shorter than the leaves. Leaves opposite, petioled,

thick, firm and subcoriaceous, oblong-lanceolate, 4—10 in.

long, including the petiole, 3-21 in. wide, gradually

narrowed to an obtuse or subacute tip, base rounded or

slightly auriculate, obsenrely toothed towards the tip,

stellate hairs beneath; nerves conspicuously impressed

above and raised beneath. Inflorescence terminal, com-

globose in outline, shorter than the leaves, about 6 in.

across, everywhere stellate-tomentose. Bracts scale-like

Jong as the calyx or even rather longer. Flowers white,

almost sessile, 24-33 lin. across. Calyx tomentose, with

small ovate rather blunt lobes. Corolla almost rotate,

lobes oblong-ovate, blunt. Stamens 5, exserted; filaments

filiform ; anthers oblong, yellow. Ovary inferior, 1-celled

The handsome Chinese Spiraea here figured is, as Mr.

Bean points out, most nearly allied to the Himalayan

S. canescens, D. Don, and the Chinese S. Henryi, Hemsl.

From the former it is readily distinguished by its glabrous

leaves, which are never toothed towards the tip as they

usually are in S. canescens; from the latter it is distinguished

by the same characters and in addition by the fact that in

hed Flenryi the leaves are very considerably larger. In the

original description some stress has also been laid on the

distichous arrangement of the branches in S. Veitchii; this,

however, is a character which is more apparent than real,

‘nd cannot therefore be said to be altogether distinetive.

The short flowering twigs, from whatever aspect of the

stem they may originate, always assume an erect position,

With the result that every corymb faces upwards and is

situated in the same plane as its neighbours. This ne

ment, which imparts to the branchlets the nl y

distichous disposition alluded to, transforms the arching

Juty, 1911,

branches on which the corymbs are borne into long flower

sprays of striking and singular beauty. Mr. E, H. Wilson,

who discovered this species in Western Hupeh in 1900

(Herbarium No. 2276) when collecting for Messrs. J. Veitch

& Sons, and introduced it that year to European gardens,

informs us that he considers it the finest of the Chinese

Spiraeas. This opinion has not been belied by experience

since it was expressed, and as there appears to be no doubt

as to the perfect hardiness of the species, it should make a

valuable addition to cultivated shrubs, The original plants

in Messrs. Veitch’s nursery at Coombe Wood, from one of

which, in flower in July, 1909, the material for our figure

was obtained, make growths six to eight feet long in a

season, Such shoots are barren the first year, but in the

following season develop short flowering branches from the

nodes. Like nearly all the Spiraeas, S. Veitchii requires a

rich loamy soil and can be propagated by late summer

cuttings. Such pruning as it requires consists of the

removal of old and crowded stems as soon as the plant is

out of flower.

Descriprion.— Shrub up to 10 or 12 ft. high, of spreading

habit; branches very leaty, arching, graceful, reddish when

young and covered the first year with a close pubescence.

Leaves deciduous, entire, oval, oblong or occasionally

obovate, cuneate at the base, rounded and with a small

mucro at the apex, 3-1} in. long, 4-3 in. wide, glabrous

The handsome Dracocephalum which is the subject of our

plate belongs to the small section Luyschiana, looked upon

by authors earlier than Linnaeus as a separable genus,

Joty, 1911.

which is characterized by having villous anthers. This

section includes the two species D. Ruyschiana, Linn., and

D. austriacum, Linn. To these two plants D. argunense

is very closely allied, especially to the former, from which

it is only to be satisfactorily distinguished by its much

larger flowers; the latter, which agrees with our plant as

regards the size of its flowers, is readily distinguished by

being much more hairy and by usually having divided

leaves whose segments are spinescent at the tip. In his

recent Flora Mandshuriae, however, Mr. Komarov has

retained D. argunense as a distinct species, a decision with

which we fully concur. Komarov also unites with our

plant the Japanese one described by the late Professor Gray

as D. Ruyschianum, var. japonicum, though it has to be

remarked that the specimens of this Japanese plant in the

Kew herbarium have the calyx much more hairy. The

typical form, now figured, is a native of Dahuria,

Mandshuria, the Amur region and the province of Chili

in North China. It is an old denizen of European gardens,

having been first introduced in 1822. The Japanese form

was apparently first introduced by Messrs. J. Veitch & Sons,

who had it in cultivation at Coombe Wood in 1879, when

it was figured in the Gardeners’ Chronicle under the name

suggested by Gray. This introduction was effected through

the agency of the late Mr. C. Maries, who had obtained the

plant on the central mountains of Japan. The reintro-

duction of the typical form has again been due to Messrs.

Veitch, who received’ seeds in October, 1909, from their

collector, Mr. W. Purdom. These seeds were obtained at

Weichang in Northern Chili; the plants raised therefrom

reached a flowering size in August, 1910, when the material

on which the accompanying figure has been based was sent

from Coombe Wood, where, Messrs. Veitch inform us, the

plant grows well in good sandy loam and in a sunny

situation.

Descriprion.— Herb, perennial; stems slender, usualiy

several, simple, 1-2 ft. high, more or less hairy, especially

at the nodes, sometimes nearly glabrous lower down.

Leaves linear, linear-lanceolate or lanceolate, 14-23 in. long,

1-2 rarely as much as 5 lin. wide, obtuse, or occasionally

slightly emarginate, narrowed at the base to a very short

petiole, margin entire, slightly revolute, scaberulous above,

finely glandular-punctate beneath, often hispidly ciliate,

often with short axillary branches bearing smaller leaves,

The Horned Cucumber which is the subject of our illus-

tration was originally discovered by Drége in Pondoland

in the vicinity of St. John’s River, But although it was first

reported from South-east Africa, the plant would appear to be

rare there, for it has not been met with by any subsequent

collector. In Tropical Africa, however, it is very widely

distributed ; it has been reported from Nubia, Abyssinia

and Jur, as well as from Mozambique on the eastern side

of the continent; from N igeria, Cameroons and Angola on

the western side. The specimens in the collection at Kew

Were raised from seeds presented to the establishment in

1899 by Mr. ©. H. Stanton, Field Place, Stroud ; these

seeds had been collected by Major A. E. Stanton, of the

11th Soudanese, while serving at Khartum. The plant

when given the treatment suitable for the common Cucum-

Juty, 1911.

ber grows vigorously and fruits freely. The fruits are

of an olive green colour until they are quite ripe, when

they become rich scarlet; they remain on the stems long

after the latter are dead, and at this stage, as they hang in

the late autumn from the rafters of the Tropical Aquatic

house at Kew, along with the fruits of the other gourds

grown there, are highly ornamental. C. metuliferus is

easily propagated from its seeds, which are produced in

quantity.

Description.— Herb; climbing by means of tendrils.

The figure of the striking Cypripedium given in our

plate has been prepared from a plant sent to Kew for

identification by the establishment of Bees, Limited, with

whom it flowered in June, 1910. The species is one with

a somewhat interesting history. It has been in cultivation

in this country for a number of years and, at all events at

the time of its introduction as well as for some time there-

after, was accepted as being C. macranthum, no doubt owing

to the fact that the figure of the plant in the Japanese work

So mokou Zusetsu bears this name. It is, however, quite

distinct from the original C. macranthum, Swartz, figured

at t. 2938 of this magazine, which has flowers of a uniform

deep rose-purple shade. Franchet and Savatier, fully

realising this, have thought it to be the same as C. macran-

thum, var. ventricosum. But it is equally distinct from the

plant so named by the younger Reichenbach, and Professor

Matsumura on discovering this fact has concluded that it

Juiy, 1911.

must be the Japanese plant described by Blume as

C. Thunbergii, with the result that of late years this Cypri-

pedium has, in all carefully determined collections, been

grown under that name. But an examination of the

original type of C. Thunbergii, Bl., for an opportunity of

studying which we are indebted to the kindness of Dr.

Goethart of the Leyden herbarium, shows that, of the three

suggestions from time to time adopted, that of Matsumura

happens to be the least satisfactory. Our plant is un-

doubtedly a near ally of C. macranthum, though it differs

too greatly to admit of its being included therein; with

C. Thunbergii its affinity is much more remote. So far as

we know at present C. macranthum does not occur in Japan,

and C. speciosum, which seems to be widespread in that

country, may be looked upon as its representative. Besides

the coloured figure given in the So mokou there is another

in the older Honzo Zufu. In this latter figure, however,

rose-coloured blotches are depicted on the lip; these have

not been met with so far in any living specimen and would

appear at least to be unusual. The cultivation of C.

speciosum presents no great difficulty, the conditions suitable

for C. macranthum being also suitable for our plant.

Descriprion.—Herb ; stems erect, rather stout, pubescent,

leafy, 8-16 in. high. Leaves sessile, ovate- or elliptic-

oblong, acute or shortly acuminate, ciliolate, shortly pube-

scent, 3-4 in. long, 3-2 in. wide, plicate. Bracts leafy,

large, ovate, acute. Flowers showy, whitish or pale flesh-

coloured, veined with rose. Sepals: upper ovate, acute or

‘ POLYPODIUM.

Gen. Char. “Sori dorsal, subglobose or oval, destitute of

2. Polypodium vulgare, L. Common Polypody.

Caudex stout, widely creeping, scaly. Fronds ovate-oblong.

Sori round, placed in a row on either side the mid-vein.

The name of this well-known fern is formed from two

Greek words, polys, many, and pous, podos, a foot; and

is applicable because of the many rootlets thrown out

from the caudex.

The form of the frond is very variable,—we sometimes

find it eighteen inches long,

while the plants that grow on

old walls have often fronds

not more than three inches”

in length. The caudex creeps |

equal, opposite, and slightly

waved or jagged at the mar-

gin. Each pinna has a mid-

vein, from which branches

issue, and the fructification is

situated at the point of the side veins.

The genus Clusia includes nearly a hundred ae:

natives of Tropical America and the West Indies. Al

Avausr, 1911,

appear to be dioecious; many, including the subject of our

plate, are epiphytic. Though they are not parasites these

epiphytic species nevertheless in time usually destroy the

trees on which they grow by strangling them. C. grandi-

flora, here figured, is a native of Guiana and belongs to the

group Chlamydoclusia, Engl. the species included in which

are characterised by the peculiar structure of their male

flowers, which have, within a shallow cup composed of the

united filaments, a central deep yellow discoid gummy mass

composed of a very large number of staminodes agglutinated

together and overlaid by a layer of soft resin. The material

on which our illustration has been based was derived from

a plant in the Cambridge Botanic Garden which flowered

in July, 1910, when specimens were forwarded for study

by Mr. R. Irwin Lynch. This plant, Mr. Lynch informs

us, was received at Cambridge from the gardens of the

Royal Botanic Society at Regent’s Park twenty-two years

before. At Cambridge it has flourished in a stove in which

the temperature in severe winters has been as low as 55° F’. ;

for some seasons past it has flowered annually. The plant

is now 9 feet high, and has six branches fully furnished

with fine leaves, some of which are as much as 18 inches

long and 74 inches across; testimony as to its epiphytic

habit is _afforded by the production of numerous roots

varying in thickness from that of a lead pencil to that of

one’s little finger. Its cultivation among other tropical

plants has not given rise to any great difficulty ; the best

soil appears to be a mixture of fibrous peat and loam with

good drainage. The pot need not be large; that used for

the Cambridge plant has been a ten-inch one. The plant

loves moisture both in the air and at the root; it may be

propagated by cuttings, though some time is required and

six months may be necessary to establish a specimen. The

Species 1s not susceptible to insect-pests.

Drscriprion.— Shrub, dioecious, 10-20 ft. in height,

epiphytic on large trees which it embraces and ultimately

strangles by means of its roots; juice yellowish, viscid;

branches thick, spreading, somewhat angular; twigs about

3 I. thick, green and smooth. Leaves clustered towards

the end of the twigs, opposite, distinctly petioled, obovate

or elliptic-obovate, apex rounded, base obtuse or somewhat

cuneate, sometimes unequal, margin entire, 6-12 in. long,

3-6 in. wide, coriaceous, glabrous, dark green above with

the lateral nerves obscure, paler beneath with the lateral

nerves faintly visible, but marked with numerous blackish

ascending lines, midrib prominent on both sides; petiole

3-43 in. long, partially stem-clasping at the base, flattened

on the upper aspect in the lower third. lowering twigs

appearing in the axils of the upper pair of leaves on a shoot,

each over 1 in. long and each with one pair of cataphyllaries

and 1-3 pairs of leaves. Cymes terminal, 3-2-flowered ;

peduncles over | in. long, slightly decurved ; pedicels 1 in.

long or rather longer; bracts deltoid-ovate, about 3 in.

long ; bracteoles like the bracts, obtusely keeled and rather

shorter. Male: Sepals 6, white with rosy margins, in three

pairs, the outer and inner in front and behind, the central

pair lateral; outer sepals smaller than the rest, wide ovate-

elliptic, central transversely elliptic, 2 in. long, 14 in. wide,

inner elliptic, nearly 1} in. long, 1 in. wide. Petals 8,

white, rosy towards the base, with pyriform outline, about

24 in. long, 2 in. wide, with a wide slightly umbonate

smooth centre. Stamens about 500, ivory white, irregularly

3-serlate, the outer larger than the others; filaments

connate below in a cup about 14 in. across and 3 in. deep,

their free portions 1 lin. long or less; anthers opening

laterally, those of the outer series linear, slightly narrowed

upwards, about 24 lin. long, with a broad connective which

is produced as a subulate appendage as long as the anther,

those of the inner series about half as long, with a very

short appendage. Staminodes very many, agglutinate in

a central discoid gummy mass about 3 in. wide and over

4 in. high. Female: Ovary subglobose; stigmas 14-15,

sessile, radiate. Capsule broadly ovoid, white, depressed

globose and 14-15-valved when it dehisces. Seeds many,

enveloped in an orange-coloured arillus.

The pleasing Torenia here figured, which is striking on

account of the colour of its corolla and is remarkable for

the unusual length of its corolla-tube, is a native of the

island of Sumatra and of the central portion of the Malay

Peninsula. In Perak and Selangor, according to Mr.

Ridley, it occurs, often in considerable clumps, on clay

banks. A member of the section Nortenia, Benth., which

Du Petit Thouars looked upon as a distinct genus, the

plant here figured deviates considerably from the more

typical members of that group in having a calyx which is

faintly angled only and not winged. In this respect it

approaches most closely to the well-known 7. asiatica, Linn.,

August, 1911.

firured at t. 4249 of this work, and when the plant was

originally dealt with in the light of herbarium material, the

somewhat comprehensive view of the limits of 7. asiatica

adopted by Bentham in 1846 (DC. Prodr. x. 410), and

further extended by Hooker in 1884 (Fl. Brit. Ind. iv. 277),

appeared to justify the inclusion of this Malayan plant in

that familiar species. This view has not, however, been

generally adopted. The material from which our figure

and description have been prepared was obtained from a

plant presented to Kew in 1909 by the late Col. Beddome,

from his interesting collection of uncommon stove and

greenhouse plants at Sispara, West Hill, Putney. Col.

Beddome had originally obtained this plant from Sir F.

Crisp, to whose collection at Friar Park, Henley, it had

come, as 7. rubens, from an Erfurt nursery. This alterna-

tive suggestion has some justification, for 7. rubens, Benth.,

like T. asiatica and like the plant here figured, has a

calyx which is keeled only and not winged. But the colour

of the corolla is very different in 7. rubens, and there

appears little room for doubt that Mr. Ridley, to whom the

plant. now figured is familiar in a wild state, is fully

Justified in treating it as a distinct species. Like the other

species of Zorenia in cultivation, 7. atropurpurea thrives

well in a warm, moist house, and may be used as a basket

plant or grown, where there are borders of soil, as under-

growth, since the plants readily spread over the surface and _

flower freely. In its coloration and in the form of its

corolla L. - atropurpurea provides a marked contrast to

L. Fournieri, Linden, figured at t. 6747 of this work, the

Species that is now perhaps most frequently employed in

this way; another characteristic difference will be found

in the fact that the stigmatic lobes of 7. atropurpurea are

uot sensitive as is the case with those of 7. FMournert.

Descriprion.—T//erb, perennial ; stems slender, branched

and prostrate, sometimes rooting at the nodes, sparingly

puberulous, sometimes reaching 2 ft. in length. Leaves

petioled, ovate or deltoid-ovate, 211 in, long, 1-2 in. wide,

acute, base cuneate or su btruncate, serrate, often scaberulous

sbove, almost glabrous beneath ; petiole 2-3 lin. long.

flowers usually solitary, peduncled at the ends of the stem

aud branches. Peduneles 3-1 in. long, often geniculate,

2-bracteate below the middle; bracts small, linear. Caly.

narrow tubular, $ in. long, sparingly puberulous, obscurely

angled but not winged, deeply 5-lobed; lobes subequal,

erect, linear-lanceolate, about 5 lin. long. Corolla dark-

purple, 14 in. long ; tube narrowly funnel-shaped, incurved,

much exceeding the calyx, the lower half narrow cylindric,

1 lin. wide, the upper half gradually expanding, the throat

5 lin. across; limb spreading, about 1 in. wide, subequally

4-lobed, the lobes faintly crenulate with the uppermost

sometimes emarginate. Stamens didynamous, the longer

pair slightly exserted, their filaments shortly denticulate

some distance above the base, the shorter pair hardly

exserted ; anthers cohering in pairs. Style shortly exserted.

Capsule subellipsoid, glabrous, rather shorter than the

calyx.

The Landolphia here figured is widely spread throughout

Kast Africa, where it extends from the Bahr-el-Ghazal and

Mombasa through German East Africa to. Nyasaland and

Mozambique. As the number of names that have been

applied to it indicates, the species is evidently a very variable

one, and what have been taken for distinguishable forms

or varieties may represent little more than individual or

local states. The species, generally known in East Africa

as the “ Mpira,” was first added to the Kew collection in

Avaust, 1911.

1879, when seeds were sent by Dr. (now Sir J.) Kirk from

Zanzibar. In 1892 another plant was received at Kew

from the Jardin des Plantes, Paris. This latter plant,

which has been grown since then in the Tropical Economic

House at Kew, flowered there for the first time in July,

1910, and provided the material on which our illustration

has been based. The flowers are pure white and sweetly

scented; the fruit, which varies in shape from globose on —

the Lower Zambesi to pear-shaped in German East Africa,

is edible; the latex yields a rubber, but only of inferior

quality. The plant thrives well under tropical conditions,

and is easily propagated by means of stem-cuttings.

Description.—Shrub, climbing by means of the inflo-

rescence; young twigs rusty-pubescent or tomentose.

Leaves elliptic or oblong-elliptic, subacute or often obtuse,

3-43 in. long, 14-2 in. wide, coriaceous, at first loosely

pubescent on both sides, at length becoming glabrous;

lateral nerves 6-8, rarely 10 on each side, reticulation fine ;

petiole about 4 in. long. Panicle pedunculate, of varying

length, bearing numerous sessile flowers clustered at the

tips of its spreading or recurved, thinly rusty-pubescent or

The striking Mormodes here figured was introduced by

Messrs, Sander & Sons, St. Albans, from Peru, where it had

been obtained in the Moyobamba region by their collector,

Mr. Forget. The species flowered for the first time in

cultivation in July, 1909, at St. Albans, and was described

from material supplied by Messrs. Sander, from whom a

plaut was thereafter acquired by purchase for the Kew

collection. This plant, which has thriven well in an inter-

mediate temperature, under the treatment most suitable

for the allied genus Catasetum, flowered at Kew in

January, 1910, and developed a much longer spike with a

more strongly three-lobed lip than the plant on which the

original description was based. The figure here published

has been drawn from the plant at Kew, which flowered

again in January, 1911. MM. revolutum is allied to the

Colombian M. speciosum, Lindl., but differs in the characters

enumerated by Mr. Rolfe. Another species of similar habit

Aveust, 111.

is the recently described J. Wolteriana, Kraenzl., which

however differs, according to the published account, in

having the inside of the lip and parts of the column hirsute.

Descriprion.—lerb, epiphytic ; pseudobulbs fusiform-

oblong, 43-5 in. long, clothed with membranous, striate,

imbricate sheaths. Leaves recurved, elongate-lanceolate,

acute or acuminate, 3-5-nerved, plicate, firm, 6-12 in. long,

The genus Mutisia includes upwards of sixty species, all

confined to the higher ranges of the Andes of tropical

South America. Many of these are of considerable beauty

and interest and well worthy of cultivation. As yet,

however, only five or six species appear to have found

their way into European gardens, and only three plates

in this work, t. 2705, t. 5273 and t. 6009, have so far been

given to the illustration of the genus. The species now

figured, M. Clematis, is a native of Peru and Colombia and

is the second of the group characterised by having pinnate

leaves to appear in this Magazine; the pinnate-leaved form

already depicted, I. speciosa, Ait., described under t. 2705,

differs very markedly from our plant in having strongly

reflexed outer involucra]l bracts. The nearest ally of

M. Clematis is, however, M. grandiflora, Humb. et Bonpl.,

which has larger and fewer leaflets, larger flower heads,

Aveust, 1911.

longer anthers and acutely tipped involucral bracts. Of

the various species that have been brought under cultiva-

tion M. Clematis has proved much the easiest to manage.

Thirty years ago it clothed a considerable portion of the

South Octagon in the Temperate House at Kew, its shoots

growing as vigorously as a Cobaea and providing an

abundant crop of flowers every spring. The plant from

which the material used for our illustration was derived

grows against a pillar in the Himalayan section of the

same house, where it flowers freely in May. Evergreen in

habit, it has the disadvantage of presenting a somewhat

unprepossessing appearance in winter, owing to its foliage

and young shoots suffering to some extent, but by the

removal of all weak growth early in the year the plant

very soon comes into condition again. It can be propagated

sie cuttings formed of half-ripened shoots, as well as from

seeds,

Descriprion.—LHerb, climbing; stem rather woody,

Three species of Acineta have already been figured in this

work, viz.:—A. Barkeri, Lindl., as a Peristeria, t. 4203 ;

A, superba, Reichb. f. (A. Humboldtii, Lindl.), also as a

Peristeria, t. 4156; and A. densa, Lindl., t. 7143. Most of

the species have flowers of a yellow ground colour, but

Reichenbach has described as A. Hrubyana, Reichb. f., one

with flowers of a whitish ground colour and very few spots,

To A. Hrubyana, which is rare in collections, our plant is

closely allied; it is readily distinguished by the flowers

being more copiously marked with reddish brown spots, and

differs considerably in the structure of the lip. Our piant

was purchased at Bruges, from Messrs, Sander & Sons, for

the Royal Botanic Garden, Glasnevin, in 1903, as a distinet

but unnamed species, It grew well, Sir F. W. Moore

informs us, in a mixture of Osmunda fibre, good peat,

and charcoal in a_ basket: suspended from the roof of

SEPTemeer, 1911.

an intermediate orchid house with a minimum night

temperature of 55° F., and flowered for the first time in

July 1905. Flowers and photographs submitted to Kew

indicated that the plant was new to science, but fuller

material was desirable. With some of the Acinetas the act

of flowering, at least when under cultivation, has an

exhausting effect. This species has been no exception to

this rule, and it was not until July 1909 that it flowered

again. From the material then supplied our figure anda

diagnosis of the species have been prepared. Though

smaller than most of the known species, and though some-

what less vigorous than these in growth, A. MJoorei does

not deserve to be spoken of as delicate. It thrives well

under the conditions already mentioned, but requires rest

when a season’s growth is finished,

The Viburnum which is the subject of our illustration is

a Chinese species which was originally described from

specimens collected in the Patung district of Hupeh in

Central China by Mr. A. Henry, by whom the plant was

subsequently met with in Szechuan. The plant from

which our plate has been prepared was introduced to

cultivation in 1901 by Mr. E. H. Wilson for Messrs. J.

Veitch & Son, in whose nursery at Coombe Wood it has

since been grown without any protection. «It is, from the

horticultural standpoint, distinct and striking on account

of its paniculate inflorescence as contrasted with the flat

corymbs of most of the species of Viburnum in our gardens.

Its value as a shrub in collections is further enhanced by

its evergreen habit, a character which is not common among

Sertemper, 1911.

hardy species. The beauty of V. Henryi is, however,

greatest in September, when the fruits are of a beautiful

coral-red and are only beginning to turn black. In habit

it is somewhat stiff and rather sparingly furnished with

leaves. It is easily propagated by means of cuttings made

of fairly ripened wood and placed in gentle heat, Like

most of the species of the genus it prefers a cool, moist,

loamy soil.

Descriprion.—Shrub, showy when in fruit, sometimes

erect and stiff, 10-14 ft. high, sometimes, according to

Henry, in a wild state clambering on rocks, evergreen,

nearly glabrous everywhere except on the bud_ scales;

flowering twigs terete, rather slender; internodes shorter

than ihe leaves. Leaves opposite, petioled, coriaceous,

oblong or ovate-oblong or lanceolate, sometimes narrowly

lanceolate, up to 6 in. long, but usually 2-4 in. long,

narrowed to both extremities or more or less rounded at

the base, callous-toothed and sometimes reddish along the

margin, glabrous or very sparingly stellate-pubescent on

the main-nerves beneath, and there with sunken glands at

the junction of the nerves and midrib; main nerves 5-7 on

each side, rather prominent; petiole 114 in. long, slightly

widened upwards and faintly winged. lowers small, pale

yellow or greenish yellow, cymosely paniculate, very shortly

pedicelled; panicles terminal, pyramidal, 2-4 in. long, their

twigs red, bracteate; bracts linear, very soon deciduous, the

lowest I-14 lin. long. Calye very short, unequally

5-toothed; teeth rounded. Corolla shortly campanulate,

3-33 lin. across ; lobes rounded, faintly denticulate. Stamens

shorter than the corolla lobes, Ovary 1-locular, 1-ovuled.

Drupe coral red, deepening as it ripens, at length almost

black, 4-5 lin. long.

The genus Senecio is represented in New Zealand by

about thirty species, all of them endemic except one,

S. lautus, Forst., which is widely spread in Australia and

Tasmania. The New Zealand species constitute two natural

groups, one composed of herbaceous perennials, the other

of shrubs or small trees. The species of the shrubby group

are very distinct and easily separated ; those of the herba-

ceous section, to which the subject of our plate belongs, are

somewhat variable and difficult to discriminate. Our plant,

S. saxifragoides, is most closely allied to S. lagopus, Raoul,

but is of stouter habit, with larger and thicker leaves, more

densely villous on the upper surface. The specimen from

which the material of our figure was obtained is one of a

collection of New Zealand plants brought together by

SEPTEMBER, 1911,

Mr. H. H. Travers and disposed of by auction at the rooms

of Messrs Protheroe and Morris in 1908. It was planted,

along with various species of Olearia, in an unheated frame,

where it grew well and flowered freely in the summer of 1910.

It may prove to be hardy in England, and if so, should bea

most useful plant for the rock garden, being a perennial and

evergreen with handsome foliage, and forming, when in

flower, a strikingly beautiful object.

Descripri0n.—ZHHerb, perennial; rootstock stout, with a

densely woolly crown. Leaves radical, petioled, wide

oblong-elliptic or nearly orbicular, rounded at the apex,

slightly cordate at the base, 3-5 in. long, 13-4 in. wide,

coriaceous, margin waxy, denticulate, laxly and ad pressed

villous, but soon almost alabrous above, distinctly setose

near the magin, hoary-woolly beneath; lateral nerves 7-9

on each side, spreading at the base, somewhat incurved

towards the apex; petiole stout, up to 23 in. long, hoary-

woolly and purplish setose like the midrib. Scapes up to

1 ft. high, branched, clothed with white hairs and purple

setae ; bracts spathulate or linear, over 1 in. long;

The Clematis here figured is a Chinese plant which

approaches very closely to the Eastern Himalayan form

treated by Mr. Briihl as a variety, var. chumbica, of

C. montana, Ham.; it differs chiefly from the Chumbi

Valley plant in its coarser indumentum, and it is possible

that the two may not be specifically distinct. But until a

revision of the numerous varieties of C. montana recognised

by Briihl has been effected it is desirable to maintain

C. chrysocoma as a separate species. The plant which has

supplied the material for our figure was presented to the

Kew collection by Mr. M. L. de Vilmorin in the spring of

1910. It grew very well during the summer and flowered

abundantly from the old wood. Unfortunately, it does not

promise to be very hardy, and at the first frost died down to

the woody base, so that it was necessary to take up the plant

and house it during the winter. The plant is easily pro-

pagated by cuttings made of nearly ripened wood.

The Jmpatiens which forms the subject of our illustration

is a native of New Guinea. The plant from which the

material for this figure has been derived was raised at Kew

from a cutting sent from the Royal Botanic Garden, Glas-

nevin, and raised there, so Sir F. W. Moore informs us, from

seeds sent by Dr. R. Schlechter from German New Guinea.

It has proved a freely growing, freely flowering species,

amenable to very varied cultural conditions. It has survived

the winter and flowered well in the cool moisture of an

Odontoglossum house, with a night temperature of 50° F.;

in the dry atmosphere of a Cactus house; and in a bright

stove pit with a night temperature of 65° F. But of these

three conditions that most suitable is clearly the last men-

tioned ; the plant grows more freely, flowers more profusely

and is of a decidedly brighter colour when grown in a

stove pit. It requires a rich soil and can be readily pro-

pagated by cuttings. The nearest ally of J. LHerzogi is

SepTemBer, 1911.

TI. Hawkeri, Bull, figured at t. 8247 of this work, which is

also a native of New Guinea. They may in most cases be

readily distinguished by the fact that Z Hawkeri is partially

hairy and has dark red flowers, whereas J. Herzogii is per-

fectly glabrous and has vermilion-coloured flowers. But

while it is thus easy and, from the horticultural standpoint,

convenient to keep them apart, Sir Joseph Hooker points

out that, having regard to the conformity of the two in all

essential respects and to the circumstance that they are

natives of the same country, there is little room for doubt

that they are forms of the same species. This conclusion 1s

supported by the fact that in the Kew Herbarium there are

two authentically named specimens of J. Herzogii received

from the Berlin Herbarium, one collected in Kaiser

Wilhelmsland by Mr. Hollrung, the other obtained in New

Guinea by Mr. Lauterbach, in both of which the branches

are glandular pubescent.

Derscriprion.—fHerb ; stout, branching, branches and

twigs 4-angled, quite glabrous, spreading. Leaves 24-5

in. long, opposite low down, in whorls of 5-7 higher up,

petioled, firm, ovate or ovate-oblong or ovate-lanceolate,

acuminate, narrowed to the base, serrulate and often long

ciliate towards the base, bright green above, pale beneath,

with 8-10 nerves on each side: petiole 3-2 in. long;

glands at the base of the petiole subulate, herbaceous,

green. Inflorescence simply pedicelled ; pedicels solitary or

clustered, 13-24 in. long, slender, erect. Flowers showy,

3-% In. long, pale green. Vezxillum 3-1} in. wide, ovate-

rotund or cuneate, upper edge truncate, somewhat inturned

prominent green dorsal wing or ridge. Wings sessile, one-

third longer than the vexillum ; lobes free at the base, the

basal 3-1 in. long, obovate-oblong, 2-lobed, acute at the

base ; the distal 1-11 in, long, obcordate, the base long and

narrowly stipitate, without any dorsal auricle. Labellum

with a cymbiform acuminate limb, about 4 in. long; spur

2-23 in. long, very slender, incurved, red. /ilaments short,

Lissochilus stylites is a species which was originally

described by the late Professor Reichenbach in 1878 from

material collected by Dr. Schweinfurth near Munsa in the

Monbuttu Country, and was then stated to be allied to

L. arenarius, Lindl., but to be distinguished by the

presence of a pair of styliform capitate calli in the throat

of the lip. A plant collected by Mr. Mechow in Angola

was subsequently referred to the same species, as a form that

differs only in having a shorter crest. Another plant,

which had been received by the Hon. Mrs. Foley from a

friend at Ikom, on the Cross River, Southern Nigeria, with

the information that it grows in hot and moist localities,

flowered in her collection at Packham, Fordingbridge,

Hants, in June, 1909. This plant was exhibited at a meet-

ing of the Royal Horticultural Society and supplied the

material from which our plate has been prepared. This

Nigerian Lissochilus is considerably larger in all its parts

Octoser, 1911.

than the widely distributed L. arenarius, but agrees

extremely well with the original description of L. stylites,

and is believed to represent that species, The genus Lisso-

chilus is rich in ornamental forms; unfortunately, however,

though suitable for cultivation as garden plants, they are

not easy to manage. Some, which grow naturally in

swampy ground, require subaquatic treatment, and at Kew

species such as L. Horsfallii, L. giganteus and L. Mahoni

have been brought into flower by planting in large pans of

peat and sphagnum half submerged during the growing

period in a tank suitable for Victoria regia, with the water

at a temperature of about 75° F. Others again, like

L. Krebsti and L. ugandae, grow well for a time when

planted in a border of peat in a fairly dry house suitable

for succulent plants. All the species appear to improve if

allowed to rest in a fairly dry condition for two or three

months after the leaves have withered.

According to Mr. André the handsome Acanthad which

forms the subject of our illustration was discovered in semi-

umbrageous forests in Colombia in 1872, and was intro-

duced to cultivation by Mr. J, Linden in the following year ;

it was first described trom a piant in Mr. Linden’s nursery

at Brussels in 1874. There is, however, in the herbarium

at Kew a specimen collected in the neighbourhood of

Bogota by Mr. D. Bowman, when travelling on behalf of

the Royal Horticultural Society, which agrees so closely with

the form of Aphelandra fascinater known in cultivation

that it may safely be treated as belonging to the same

Octozer, 1911,

species. This specimen, which was communicated to Kew by

the late Mr. W. W. Sanders, was obtained by Bowman some

time between 1866 and 1868, the year in which he died.

A, fascinator is one of the most useful as it is one of the

most striking of garden Acanthads, being easy to grow in

a warm moist greenhouse and giving abundant flower during

the winter months. At Kew it is raised annually from

cuttings set in spring and grown in a rich loamy soil.

When in flower the plants do well if subjected to the

conditions suitable for tropical Begonias.

Descriprion. — Undershrub; stems terete, glabrous;

The subject of our piate is one of a well-defined group of

three clesely allied Chinese Spiraeas added to European

collections during recent years. The group as a whole is

nearly related to the Himalayan S. canescens, D. Don, which

has long been familiar in our gardens. But while readily

distinguishable from that Himalayan shrub, the members

of this Chinese group, which includes S. fHenryi, Hemsl.,

figured at t. 8270 of this work, S. Veitehii, Hemsl., figured

at t. 8383, and S. Wilsoni, the species now depicted,

approach each other more closely, and while all three are

fully entitled to separate recognition, at least, from the

horticultural standpoint, some care will be called for in

their discrimination in cases where the types are not grown

side by side. The three plants appropriately commemorate

the names of individuals who have played leading parts in

the discovery and introduction to Europe of plants from

Central and Western China. S. Veitchii will always be

easily distinguished from S. Wilsoni by its glabrous entire

leaves, its much longer flowering branches and its finely

Octoser, 1911. .

pubescent pedicels and calyx-tube. S. Zenryi on the other

hand is not so readily distinguishable from our plant by

any striking difference in structure, though the two are

unmistakable when seen growing side by side. But apart

from their difference in habit, S. Henryi will be easily

recognised by its much more frequently and more coarsely

toothed leaves, which are slightly lustrous and are less

pubescent, as well as by its laxer corymbs, with pilose

pedicels and a hairy calyx-tube. S. /denryi, moreover,

flowers about a fortnight later than S. Wilsoni does. Like

nearly all the Spiraeas, S. Wilsoni is easily cultivated

where a good loamy soil is available. It is advisable to

remove old flowering branches that have become worn out,

but any shortening back of the shoots must be avoided.

The plant flowers on short branchlets produced on the shoots

of the previous summer; the aim should therefore be to

have the latter as long as possible and to prevent them from

becoming unduly crowded. Propagation is readily effected

by making cuttings of side twigs with a “heel” in the

month of July; the flowers open in June. The material

from which our plate has been prepared was supplied from

one of the original plants of this species growing in the

nursery of Messrs. J. Veitch & Sons at Coombe Wood.

_Derscriprion.—Shrub, of graceful habit, ultimately 6-8 ft.

high, with long arching branches and purplish pubescent

young shoots. Leaves deciduous, rather firm, oval or

obovate or oblong, somewhat acute or quite blunt at the

nip, cuneate at the base, either entire—especially on the

flowering branchlets, or with a few teeth near the apex

Tlie Rhododendron here figured is a member of the group

of Eurhododendra, the species of which are characterised by

being more or less lepidote both as regards leaves and

flowers, and by having both leaves and flowers of medium

size, the latter often yellow and in few flowered corymbs.

This group is represented in China by a considerable

number of closely related forms, including &. Jlutescens,

Franch., and &. concinnum, Hemsl., which is also in culti-

vation in this country. ‘he nearest. ally of the form here

described is perhaps the Himalayan &. triflorum, Hook. f.

Mr. E. H. Wilson on behalf of Messrs. J. Veitch & Sons, to

whom we are indebted for the material from which our

figure has been prepared, will be welcomed in gardens as

an addition to the scanty number of species with yellow

Octosrr, 1911.

flowers. Like most of the forms included in the same group,

it promises to be quite hardy. It thrives in a moist but not

too heavy soil free from calcareous matter. It seems likely

to produce good seed under cultivation, but failing its pro-

pagation in this manner may be increased by cuttings.

Descriprion.— Shrub, closely branched ; flowering twigs

rather slender and naked except for a few glands. Leaves

persistent, scattered, petioled, lanceolate, including the

petiole 13-3 in. long, acuminate, with a subglobose apical

gland, rounded at the base, at first closely glandular-scaly

on both sides but soon becoming naked above, pale beneath

The Buddleia which forms the subject of our illustration

was originally discovered by Dr. Piasezki in the provinces

of Shensi and Kansu in Northern China, and was first

described from his specimens by the late Mr. Maximowicz

thirty years ago. The name JB. officinalis, then applied to

it, has reference to the circumstance that, according to

Piasezki, the flower buds are collected and carried to

Hankow, where they are sold as a medicine. The plant

has since been found by Mr. A. Henry in the province of

Hupeh in Central China, and has more recently been met

with in the Yang-tze valley by Mr. E. H. Wilson wher

collecting on behalf of the Arnold Arboretum. To Wilson

horticulture is indebted for the introduction of the species

to cultivation, and the material for our figure has been

obtained from a plant raised from seed presented by

Professor Sargent in 1908, which flowered at Kew in

Ocroser, 1911,

November, 1910. B. officinalis promises to be a useful

winter flowering plant for greenhouse decoration, a class to

which additions are always welcome. It may prove hardy

in the extreme south-west of England, but elsewhere will

call for treatment such as is given to B. asiatica and to pot

chrysanthemums. The cuttings should be rooted in bottom

heat in spring and grown in pots of rich loamy soil.

During summer the plants should be grown in the open

air and fed liberally, the pots being plunged in ashes.

About the beginning of October, before frosts occur, the

plants should be taken indoors to flower. When thus

treated they remain in flower for about three months.

Like its ally B. variabilis, Hemsl., figured at t. 7609 of

this work, our plant varies somewhat as regards its foliage,

but is readily distinguished by the corolla, which is pubes-

cent outside, and by the different tomentum on the under

surface of the leaves.

Description. — Shrub, 3-8 ft. high, with numerous

densely grey pubescent nearly terete branches. Leaves

oblong-lanceolate to linear-lanceolate, acuminate, about

4 in. long, 4-1 in. wide, entire or sharply serrulate,

The very distinct Caladium which forms the subject of

our illustration was sent to Messrs. Sander & Sons, St.

Albans, from Peru, where it was obtained by Mr. Forget.

As it reached this country along with a consignment of

Cattleya Fex the probability is that it is a native of the

Moyobambo region. The plant which supplied the material

for our figure was presented to Kew by Messrs. Sander, and

flowered for the first time in September, 1909. Another

individual flowered simultaneously in the Royal Botanic

Garden at Glasnevin. Among Caladiums the species is

remarkable for its pubescence, a character rarely met with

in the Aroid family at all, and in this respect it is very

unlike any other Caladium in cultivation ; indeed there is

but one other species in the genus which has been described

as pubescent. This is C. puberulum, Engl., which is

undoubtedly nearly allied to our plant, but which differs

in the characters noted by Mr. Brown. There are, how-

ever, two other Aroids, which have hitherto been regarded

as species of Xanthosoma; X. pilosum, C. Koch, and X. Hot-

Novemser, 1911,

tonianum, Schott; so closely allied to C. pubescens that Mr.

Brown has found it necessary to transfer both to Caladium,

as C. pilosum, N. E. Br., and C. Hottonianum, N. EK. Br.,

respectively. So close is the affinity between C. pilosum,

N. E. Br., and C. puberulum, Engl., that it is barely possible

to distinguish the two by the characters assigned to the

latter. All three differ conspicuously from C. pubescens in

having only five or six primary veins on each side the

midrib; in C. pubescens the number varies from ten to

eighteen. C. pubescens is rather exceptional in the genus

in having an attractive inflorescence; the white limb of

the spathe renders this quite ornamental. The plant

flowers freely when grown in a tropical moist house under

the treatment suitable for other species of the genus. It is

ened propagated by division of the fleshy, potato-like

tuber.

Descriprion.—I/vrb ; tuber globose or depressed-globose,

bearing numerous bulbils. Leaves 8-12 in. long, 34-9 in.

wide, ovate-cordate or elongate cordate-ovate, somewhat

abruptly acuminate or acute, pubescent on both | sides,

The handsome Rhododendron which forms the subject of

our figure has been known for some time in collections

under the name &. Metternichii, Sieb. & Zuce. It is not,

however, the same as the plant so named by Siebold and

Zuccarini, which differs from that here depicted in having

a corolla with seven lobes, in having fourteen stamens and

in having a seven-celled ovary. ‘The form in question is,

however, the one that was originally described by Blume

under the name /Hymenanthes japonica; to the use of this

earlier specific name Schneider has recently reverted, though

it is remarkable that in doing so he has not alluded to the

existence of the variety now figured. Like the typical

plant our variety is wild in the mountains of Central

Japan, and both are frequently met with in gardens in

November, 1911.

that country. In spite, therefore, of their rather striking

differences the two appear to be races rather than varieties

of the same species. ‘The cultivation of this Rhododendron

does not differ from that which is suitable for Rhododendrons

generally. It likes a soil preferably but not necessarily of

a peaty nature and free from lime; it requires abundant

moisture. When peat is not readily available a plentiful

admixture of decayed leaves forms a good substitute. The

plant from which the material for our plate was obtained

1s one imported from Tokyo in 1894; at Kew it grows as

a low spreading bush.

Descriprion.—Shrub; branches glabrous. Leaves ‘ob-

lanceolate, apex bluntly mucronate, base somewhat cuneate,

about 3 in. long, 3-14 in. wide, firmly coriaceous, green,

glabrous and closely reticulate above, rusty tomentose

beneath; petiole about 2 in. long, stout, transversely

rugose, at first finely pubescent, at length glabrous. Bud-

scales obovate spathulate, rounded at the tip, reaching | 1.

in length, membranous, pubescent on both surfaces. Bracts

linear-filiform, 5 lin. long, pilose. Pedicels 1-1} in. long,

sparingly clothed with crisped hairs. /Vowers about 34 in.

across, Caly« short, 5-toothed; teeth triangular, rather

blunt, sparingly pubescent. Corolla almost campanulate,

rose-coloured, 5-lobed ; tube 3 in. long, glabrous without

1 in. wide. Stamens 10-11, hardly exserted ; filaments

unequal, over 1 in. long, puberulous below, glabrous

above; anthers yellow, nearly 2 lin. long. Ovary 5-celled,

The genus Leonotis comprises about twenty species, all

but one of which are limited to Tropical or South Africa.

The exception, L. nepetacfolia, R. Br., is widely distributed

in tropical regions, being found in the Mascarene Islands,

Tropical Asia and America, apparently often as a weed.

LL. Leonurus, R. Br., a deservedly popular winter-flowering

greenhouse plant and the most attractive of the genus, is a

native of the Cape, and like many Cape plants has become

naturalised in West Australia (Benth. F). Austral. vol. v.

p- 74). This species bas been in cultivation since 1712,

and was figured in this work under the name of Phlomis

Leonurus, Linn., at t. 478, more than a century ago, A

few other species have been introduced into gardens, such

as DL. intermedia, Lindl, £. ovata, Spreng., L. dubia, KE,

Novewser, 1911.

Meyer, and LZ. nepetaefolia alluded to above, The subject

of our plate, L. dysophylla, is recorded from the Orange

River Colony, the Transvaal, Transkei, Griqualand East

and Natal. The plant which supplied the material for the

illustration flowered in January last in the Cambridge

Botanic Garden, having been raised there from seed

received from Mr, G. Thorncroft, Barberton, Transvaal. The

seed was sown in an Intermediate House in February; the

plants were grown on and planted out of doors for the

summer, and given very much the treatment of bedding

plants. The more vigorous individuals were taken up in

autumn and flowered in pots during the winter. The

species may, Mr. Lynch informs us, be grown as an

ordinary greenhouse plant under the treatment suitable for

L. Leonurus, and, as in the case of that species, stopping

must be done with discretion, so as to secure the strongest

possible flowering shoots.

Description.— Herb; stems stout, 2-3 ft. high or taller,

woody at the base, densely puberulous. Leaves ovate-

lanceolate, occasionally ovate, 3-35 in. long, over 1 in.

wide, obtuse or subacute, narrowed to the base, rather

regularly crenate or crenate-serrate, shortly softly pubes-

cent or often densely villous, especially beneath, often

rather thick ; petiole 2-11 in. long. Verticillasters solitary

or two superposed, large and many-flowered ; bracteoles

linear, 3-2 in. long, spinescent at the tip; pedicels over

1 lin. long. Calyx almost tubular, incurved, 3-1 in. long,

adpressed puberulous; teeth 8, spinescent, the uppermost

deltoid-ovate, 2-3 lin. long, much larger than the rest.

Corolla orange, 1-14 in, long, incurved, densely villous

outside above; tube almost cylindric, as long as the calyx-

tube; upper lip oblong, concave, 2-3 in. long, entire; lower

lip 3-lobed, 4-5 lin. long, mid-lobe obovate, retuse, 3-4 lin.

long, lateral lobes elliptic, rather shorter. Stamens ascend-

ing under the upper lip; filaments villous. Style ultimately

rather longer than the stamens, 2-fid, the posterior lobe

very small. Nutlets somewhat trigonous, with truncately

rounded tips, finely papillose; disk cupular, rather deeper

The Phyllodoce here figured is one of the daintiest of the

Ericaceae, forming neat dense tufts of erect stems a few

inches high. It is cultivated at Kew in a mixture of peat,

leaf soil and sand, and flowers profusely in May, the plant

being then almost hidden by the pinky white bells. It is

admirably adapted for a moist nook in the Rock Garden

where there is peaty soil. If a spot can be selected where

a boulder throws a shadow over the plant for a few hours

about midday but otherwise leaves it fully exposed it would

be an advantage. The origin of our plant is obscure. It

may be said to come nearer to P. intermedia than it does to

P. empetriformis on account of its small short anthers, but

November, 1911.

it differs from both these well-known species in the white,

widely campanulate and not urceolate corollas. The anthers

indeed at first sight suggest that they may be imperfect

and that the plant is a hybrid, but they contain pollen

which appears to be quite normal, and the plant besides

produces abundant seed. There is little doubt that it 1s a

native of the Rocky Mountains or of the Cascade Range,

the habitat of P. empetriformis and its immediate allies, but

as to the exact home of the charming plant now described

we are at present without a clue, It is easily propagated

by cuttings in sandy peaty soil made in July and placed in

a close slightly heated frame.

Descriprion.—Shrublet, about 6 in. high; branches erect,

rigid, closely leafy; twigs sparsely beset with blackish

glandular setae and lines of minute hairs. Leaves close-

set, subsessile, linear, obtuse, with distinctly recurved edges,

3-4 lin. long, under 1 lin. wide, smooth and glabrous above,

beneath 2-suleate owing to the stout midrib and the reflexed

edges, densely white papillose along the midrib, finely

spinulose serrate or, in the upper leaves, glandular ciliate

in the folds, FVowers in clusters of 5-7 at the tips

of the twigs, axillary; pedicels filiform, 3-1 in. long,

reddish, glandular pubescent, surrounded at the base by

According to Morren the Auellia here figured was intro-

duced from Brazil in 1875 by Messrs. Jacob-Makoy of Litge

and was named &. Devosiana in their catalogue of 1876 in

compliment to Mr..A. Devos, then in charge of the botanical

collections of the University of Liege. Morren, with some

reason, compares it with #. picta, a plant of rather doubtful

status figured by Loddige in 1828, without analysis or

description, at t. 1448 of the Botanical Cabinet. Lindau has

treated FR. Devosiana as identical with R. Schaueriana, a

view which it is not convenient from the horticultural stand-

Novemser, 1911.

point to accept, and one that could only be adopted if

ft. Schaueriana be treated as a very variable species which

includes R. calvescens as well. A figure of R. Schaueriana

has been given at t. 4147 of this work under the name

R. lilacina. It differs from R. Devosiana in having firm,

somewhat shining leaves that are almost or quite glabrous,

in having larger lilac to purple flowers, and in having a

different ovary. In this work, however, two other plants

that approach even more closely to R. Devosiana than

R. Schaveriana does have also been figured ; one at t. 4366

as Strobilanthes lactatus, the other at t. 5106 as Dipterac-

anthus calvescens. Of these the former is readily distin-

guishable from R. Devosiana, because its leaves are very

like those of A. Schaueriana ; it differs from &. Schaueriana

in having a more slender ovary. The latter, which is

believed to be the same as R. calvescens, differs con-

siderably from R. Devosiana as regards the indumentum on

the stem and leaves and has an ovary like that of the plant

figured as Strobilanthes lactatus. It is, however, necessary

to remark that, in his review of the Acanthaceae under culti-

vation in collections, the late Col. Beddome has placed two

of these four plants under R. solitaria, a species only

known from Velloso’s figure and his rather meagre descrip-

tion, while Nees has referred &. solitaria to R. Schaweriana.

In view of this dubiety all that can with safety be said is that

&. Devosiana, here figured, belongs to a group of species

of which #. Schaueriana is the best-known member; that it

is readily distinguishable from the other members of this

group already in cultivation; and that, from the garden

standpoint, it is desirable to accord it separate recognition.

The plant from which the material for our figure has been

obtained was received at Kew in 1903 from the Jardin des

Plantes, Paris. It forms a compact little shrub and is

useful to grow as a trailer or basket-plant in a warm house.

Its flowers are produced in autumn.

Descriprion.— Undershrub, 1-13 ft. high, erect; branches

slender, angular above, ultimately cylindric below, grey-

velvety tomentose. Leaves elliptic or oblong, acute, with

cuneate base, nearly entire, 24-3 in. long, 14 in. wide, softiy

erbaceous, when young white hirsute, when full-grown

soft to the touch on both surfaces, finely velvety-papillose

_ and beset above with long hairs, rather densely along the

margins, more sparingly elsewhere; upper surface dark-

green with a white streak along the midrib, undersurface

purple; petiole slender, 4-5 lin. long. Flowers axillary,

solitary, sessile, towards the end of the branches. Bracteoles

The handsome Umbellifer which forms the subject of our

illustration is a native of the Subantarctic Islands of New

Zealand. This species, Aciphylla latifolia, and two other

members of the same genus, A. antipoda and A. acutifolia,

in association more or less with three species of the Umbelli-

ferous genus Pleurophyllum, constitute jointly the most

conspicuous feature in the vegetation of the Auckland

and Chatham Islands. For the introduction of this species

to England horticulture is indebted to Capt. A. A. Dorrien

Smith, and the material for our plate, which was sent from

the garden of Mr. T. A. Dorrien Smith, Treseo Abbey,

Isles of Scilly, has come from the first plant of this species

to flower in this country. The plant in question is a male

specimen, and unfortunately so far female flowers are not

December, 1911,

available; to complete the plate a drawing by Miss J. J.

Clark of ripe fruits, collected by Sir J. D. Hooker, and one

of a transverse section of the same, have been added. The

genus Aciphylla is in some regards the southern representa-

tive of the northern Ligusticum, and Mr. Hemsley has

followed the “Genera Plantarum ” of Bentham and Hooker

in referring this plant to the former rather than the latter

genus. This course has also been adopted by Dr. Cockayne,

whose personal knowledge of the islands in which it occurs

is so extensive. But the Umbelliferae of New Zealand

stand in need of generic revision, and Mr. Cheeseman has

suggested, with some reason, that the genus Anisotome,

proposed many years ago by Sir J. D. Hooker, should be

revived for the accommodation of A. latifolia and its

undoubted congeners.

Drscriprion.—Ierb, almost everywhere glabrous, poly-

stalked, 1-2 ft. long, ovate, twice pinnatisect ; segments

ovate-lanceolate, decurrent, with spinulous tips, their

margins thickened; veins rather conspicuous; petioles of

the leaves of the inflorescence very broad, sheathing,

cymbiform, with few apical segments or teeth. Umbels

compound, axillary and terminal, stipitate, rather longer

than the leaves, many-branched, 24-4 in. across. Bracts

linear, acute, about as long as the stout umbel-branches.

Braeteoles like the bracts but smaller, rather longer than

the flowers. Secondary umbels many-flowered. flowers

The Rhododendron which we here figure is a Chinese

species originally described by Franchet from specimens

collected in Yunnan by Delavay, where it las also been met

with by Henry and by Forrest. For its introduction to

European collections horticulturists are indebted to Mr.

M. L. de Vilmorin, who has raised plants from seed sent

to him by Ducloux in 1907. The material from which

our illustration has been prepared was supplied by Mr.

de Vilmorin from one of these plants, which flowered at

Les Barres for the first time in the spring of 1910. The

only species of A’hododendron which resembles £2. spinuli-

ferum in the peculiarly shaped corolla is R. Keysii, Nutt.,

figured at t. 4875 of this work. So striking is the deviation

from the normal type of corolla in the genus, that 2. Keysii

has been treated as the representative of a distinct section.

In other respects, however, our plant approaches more

closely to 2. spiciferum, Franch., and £&. scabrifoliam, Frauch.,

Decemser, 1911.

both of which have a calyx and a corolla of altogether

different type. Mr. de Vilmorin remarks that in general

habit R. spinuliferum bears a greater resemblance to

R. Augustinii, Hemsl., than to any other species with

which he is acquainted. R. spinuliferum is a shrub of tall

thin habit, making slender shoots one foot or more 1

length during the growing season. The leaves are disposed

evenly and regularly along the twigs, and are not clustered

near the apex of a shoot as is so commonly the case in this

genus. A plant presented to Kew by Mr. M. L. de Vil

morin is grown in peaty soil in a nursery, and during the

coldest winter weather has required to be covered by a

glass light. It has also been necessary to protect the plant

from injury by spring frosts. While, therefore, we have

as yet had but a brief acquaintance with this remarkable

species, we fear, and in this both Mr. E. H. Wilson and

Mr. G. Forrest, with their extensive Chinese experience,

concur, that it will thrive in the open only jn our mildest

counties.

DEscriPT10oN.—Small shrub, according to Forrest 3-8 ft.

high in the wild state; twigs when young finely grey-

pilose and also setase, soon however becoming glabrous ;

bark reddish-brown. Leaves lanceolate or oblanceolate,

thickened-acuminate at the tip, base cuneate, 1-1 in. long,

about 5 lin. wide, firm, rugulose above and almost glabrous,

but with seattered bristles near the margin, beneath

sparingly pilose and lepidote; lateral nerves 5-7 on each

side, impressed above, somewhat raised beneath, transverse

veins sunk above, barely visible beneath; retiole about

2 lin. long. Inflorescence terminal, usually about 4-flowered ;

pedicels 3-4 lin. long. Calyx very short, woolly like the

pedicels. Corolla red, tubular, gradually and_ slightly

narrowed towards the apex as well as the base, glabrous;

tube 7 lin. long; lobes 5, imbricate, ovate, 4 lin. long.

Stamens 10, exserted, unequal; filaments 3-14 in. long,

glabrous; anthers about 1 lin. long, almost black. Ovary

2 lin. long, woolly and sparingly glaudular ; style about as

long as the longer stamens, sparingly puberulous below.

The interesting plant here figured is a member of the

Begoniaceae, which family is now known to include five

distinct genera. In two of these, Begonia itself and //ille-

_brandia, the segments of the perianth are distinct in both

the sexes; in one of them, Begoniella, the segments of the

perianth are united in both sexes. The remaining two

genera have the perianth-segments distinct in one sex,

united in the other. In Semibegoniella it is the male flower

which has the segments of the perianth united, while those

of the female flower are free. But in Symbegonia, the

genus to which the subject of our illustration belongs, it is

the female flower in which the perianth-segments are united,

the male in which they are free. This genus is endemic

in New Guinea, and includes four species, all of which have

been discovered in Kaiser-Wilhelmsland. The plant which

December, 1911.

supplied the material for our figure was raised at Glasnevin

from seed sent by Dr. R. Schlechter from New Guinea in

1908. Only one seed germinated and the resulting plant

has been grown in an intermediate house with a mimimum

night temperature of 55° F. in a compost of fibrous loam,

peat and leaf mould. It is of branching habit, under a foot

in height. In winter most of the shoots die down to the

crown. Propagation is readily effected by cuttings.

Descriprion.—Herb, erect, 5-8 in. high; stems tinged

with red, crisply hairy, about as thick as a crow-quill

above. Leaves lanceolate-oblong, acute, very unequal at

the base and strongly auriculate on one side, 24-2 in.

long, 14 in. wide; deeply double serrate, green, shining

and finely punctulate above, finely and sparingly pubescent

on the sunken nerves, but elsewhere glabrous, more or less

tinged with red beneath and with prominent hispidulous

nerves, the fine reticulations hardly visible and_ the

mesophyll closely white punctate; petiole about 2 Iin.

long, pubescent like the stem; stipules lanceolate, their

midrib produced in a slender tip about 2 lin. long, mem-

branous, pale green, including the tip about 2 in. long and

about 2 lin. wide. Flowers 1-sexual, shortly pedicelled.

Perianth-segments in the male flower 2, free, valvate, ovate.

Stamens 12-20; filaments united in a column for most of

their length; anthers basifixed, oblong-ovate; dehiscence

lateral. Perianth-segments of female tlower connate In a

yellow campanulate tube, hairy on the outside;

obes 5, ovate, serrulate, spreading. Ovary quite inferior,

3-winged, wings almost triangular, sharply acuminate ;

styles 3, connate below, deeply 2-fid, with a spiral stig-

matic surface; placentas 2-lamellate, lamellae parallel,

bearing ovules on both surfaces.

The Pitcairnia here figured is one of the most distinct

and decorative members of the genus. It is now an old

garden plant; it was first exhibited by Mr. Linden in 1861

or 1862; his plants had been sent from Chiapas in Mexico

by Mr. Ghiesbreght. P. tabulaeformis differs from every

other known species except P. heterophylla, Beer, figured

at t. 4591 of this work under the name P. exscapa, Hook. f.,

in having a congested somewhat capitate inflorescence.

But our species is readily distinguished from P. heterophylla,

which has dimorphic leaves, the inner being linear and

grass-like, the outer much shorter and densely spiny along

the margins, by having leaves that are uniform and devoid

of marginal spines. The petals in our plant are spirally

twisted, but in such a manner as to reach different levels and

so to impart to the flower a zygomorphic appearance. In

cultivation P. tabulaeformis is easy of management; it does

well when grown under tropical conditions in a peaty soil

with an abundant supply of moisture. It ripens seed freely,

December, 1911.

and plants raised in this way reach a flowering condition

in about two years; it may also be propagated by offsets

which develop round the base of the plant after it has

flowered, Our figure has been prepared from a plant which

blossomed at Kew in June 1910.

Description.—Lerb, almost stemless. Leaves rosulate,

spreading, oblanceolate, acute, 4-5 in. long, 1-1} in. wide,

gradually smaller upwards, glabrous, margin undulate

but quite entire, with a narrow white border; nerves

numerous, very slender. J/nflorescence at first cone-like,

at length shortly racemose, many-flowered ; bracts green,

ovate; bracteoles oblong, milky white or pale yellow, their

tips tinged with red, about 1 in. long. Sepals 2 in. long,

oblong, acuminate, yellowish-white. Petals 2 in. long,

linear ligulate, bright orange, with basal scales. Stamens

shortly included; anthers somewhat sagittate. Ovary

conical, trigonous; style shortly exserted; stigma 3-lobed,

spirally twisted.

The Japanese Cherry here figured is most nearly related

to PP. serrulata, Lindl., from which it may be readily

distinguished by its few-flowered, sessile or subsessile

umbels and its broader and more coarsely serrated leaves,

the teeth of which are hardly pointed. P. serrulata has

long been in cultivation in European collections under the

name P. Pseudo-cerasus, and has been figured at t. 8012

of this work under that name. This error we have been

enabled to detect and remedy through the kindness of

Protessor Seward, who has permitted us to study the types of

Lindley’s two species which are preserved in the University

herbarium at Cambridge. P. Sargentii, the subject of our

late, was first raised in the Arnold Arboretum from seeds

collected in Japan in 1890 by Dr. Bigelow, and was again

introduced to the same collection in 1892 by Professor

Sargent who, in 1893, preseuted seeds to Kew. Sargent

December, 1911.

who, in figuring and describing the species, made the

error regarding its identity, which has so long prevailed in

this country with regard to the identity of P. serrulata,

states that the timber of this tree is highly esteemed in

Japan for wood-carving and for the preparation of the

blocks used in printing cloth and wall-paper. In its native

habitat the tree is stated to attain a height of eighty feet

with a trunk three feet in diameter. Since its introduction

to cultivation P. Sargentii has proved one of the most

beautiful of single-flowered cherries. Hitherto fruits have

not been freely borne in this country, but in the Arnold

Arboretum trees of the same generation as those at Kew

present a striking appearance in the latter part of June

because of the extraordinary abundance of their small black

cherries. The seeds these afford provide the best means of

propagation ; failing seeds the species can no doubt be

budded on Mahaleb or Gean stocks. The leaves in autumn

assume a beautiful dark red hue. The tree should be

planted in good loamy soil in a sunny spot.

Description.— Tree, sometimes reaching 80 ft. in height;

trunk reaching 3 ft. in diameter; bark tawny, beset with

large lenticels ; twigs blackish, glabrous. Buds narrowly

ovoid, acute, about 5 lin. long. Leaves obovate-elliptic or

oblong-obovate, long caudate acuminate, rounded at the

base, those lowest on the twigs subcordate, 24-34 in. long,

13-2 in. wide, sharply serrate, green above, glaucescent

beneath, glabrous on both sides, main nerves 7-10 on each

side; petiole slender, 3-1 in. long, with a pair of apical

glands. Flowers rose-coloured, 14-14 in. across, in 2—4-

flowered sessile umbels ; pedicels slender, up to 14 in. long,

with glandular serrate basal bracts. Calya tubular, about

23 jin, long, lobes ovate-lanceolate, acute, 2-23 lin. long,

entire. Petals obovate, emarginate, 3 in. long, about § in.

wide. Stamens 20-25, shorter than the petals. Ovary

glabrous; style glabrous, rather longer than the stamens.

black ; stone ovoid-globose, slightly compressed, 44 lin.
