This handsome species, Rhododendron auriculatum, is a

native of Western Hupeh where, as Mr. E. H. Wilson

informs us, it occurs scattered throughout woods without

being anywhere common. It was first collected by

Professor A. Henry, in 1885, near Ichang, and was met

with again by him in subsequent years. Wilson obtained

it in 1901 near Fang. In its native habitat this is the

: last of the Rhododendrons to come into flower and, as it

maintains this characteristic in cultivation, this fact

imparts to #. auriculatum its most important feature

from the garden point of view. At Kew, where the

species 1s represented by examples acquired from Messrs.

J. Veitch and Sons in 1908, it does not commence to

JanuaRy—Marcg, 1919. a.

grow until the latter part of July, and it flowers at the

same time. It may therefore be possible to found on it a

race of hardy hybrids later in flowering than any now in

existence, though it is difficult to find other Rhododen-

drons flowering in July with which it can be crossed. At

Kew it has been fertilised with pollen from a belated

f. ponticum, Linn. ; it has also been crossed with the late-

flowering form of R. decorum, Franch. In the wild state

the flowers of /?. auriculatum vary, so Wilson states, from

white to rosy red. They are pleasantly fragrant, their

odour recalling that of a freshly cut dessert apple. In

foliage it is perhaps the finest of all Rhododendrons

hardy in aclimate like that of the Thames valley, though

in milder districts larger leaves are borne by Himalayan

species like . Falconeri, Hook. f., and £&. grande, Wight.

The largest leaves of 2. auriculatum measured have been

thirteen inches long by five inches across. Though quite

hardy at Kew, its greater luxuriance in Cornish gardens

indicates that it prefers rather milder conditions. It

should be grown in thin woodland or in some other

position where it is protected from the midday sun.

Description.—Shrub or, according to Henry, at times a tree 30 ft. high;

shoots stout, in the first season densely hirsute with very long glandular

hairs, in the following year pustulate with the remains of the hairs, when

older, brown and glabrous. Leaves oblong or elliptic-oblong, rounded or

orbicular, about 13 in. long. Stamens 14, shortly exserted; filaments nearly

equal in length, glabrous; anthers brownish-yellow, 2 in. long. Ovary 7-8-

celled, densely beset with glandular hairs; style exserted, glandular towards

the base, tipped by the

The remarkable Brazilian Orchid which forms the

subject of our plate was described and figured by Mr.

Barbosa Rodriguez in 1877 from specimens growing on

trees at Caldas, in the province of Minas Geraes. It had,

however, been previously met with by Dr. G. Gardner,

for there is a specimen of the same plant in the Lindley

Herbarium which Gardner has noted as being a species

of Mazillaria, collected by him in March, 1837, on the.

stems of trees in the Organ Mountains. To this speci-

-men Dr. Lindley added the note, ‘‘ genus uncertain,

the only flower was broken and injured by insects.”

Rodriguez when he described the plant, which he

dedicated to H.I.H. Donna Isabel, Comtessa d’Eu,

remarked that it is a very bizarre Orchid with almost

the habit of a Mazillaria, but with a pollinary structure

JaNuaRY-Makrcg, 1919, ae

so different from that of Mavillaria that he placed his

genus /sabelia, with good reason, in the tribe Epidendreae,

between Lindley’s two genera Leptotes and Sophronitis.

In the figure of J. virginalis supplied by Rodriguez,

which serves as the frontispiece to his volume, the

remarkable fibrous sheaths which clothe the pseudobulbs

are shown as being more developed than they are in

the cultivated plant here depicted. For the introduc-

tion of this plant to cultivation, orchid-growers are

indebted to Mr. K. Grossman, who sent living plants to

the Botanic Garden at Berlin in 1904. The example

now figured was received at Kew from the Director of

the Berlin Botanic Garden in 1908, and has thriven well

in an intermediate temperature attached to a block of

tree-fern stem. © Under cultivation it flowers very

Sparingly, the last occasion being December, 1917, when

our drawing was prepared. It is by no means con-

spicuous, even when in flower, for the solitary individual

blossoms are small, and are borne on extremely short

peduncles ; they are whitish with a light flush of rose or

pale purple in the sepals. The flowers are, however,

extremely interesting on account of their remarkable

structure.

Description.—Herb, epiphytic, small, with a creeping cylindric rootstock.

Pseudobulbs 1-foliate, close-set, ovoid-globose, 3-3 in. long, clothed with

Scarious sheaths which at length become fibrous-laciniate. Leaves nearly

cylindric, rather blunt, curved or flexuous, 13-6 in. long, very narrow. Scapes

short, slender, 1-1 in. long, 1-flowered ; bracts spathaceous, blunt, very short; .

pedicels short. Flowers small, spreading, flushed with rose or pale purple.

Sepals : posterior suberect, ovate-oblong, blunt, somewhat concave, 1-1 in, long ;

lateral somewhat spreading, ovate-oblong, blunt, } in. long, shortly connate at

the base and produced into a short mentum. Petals somewhat spreading, narrow-

oblong, blunt, 3-1 in. long, somewhat narrowed at the base. Lip towards the

base very concave and more or less erect, higher up recurved and spreading,

obovate, somewhat convex, 4-4 in. wide; disk somewhat thickened. Column

nearly erect, broad, ;!;-} in. long, without wings ; pollinia 8 (4 in each locule),

elliptic - oblong, somewhat compressed; caudicles almost filiform, curved,

connate at their tips.

JANUARY-Marcn, 1919.

This Jpomoea, attractive both in foliage and in flowers,

the latter being of a colour very unusual in the genus,

has long been known in gardens. Its first recorded |

appearance was in the Calcutta Botanic Garden in 1812,

where, according to Roxburgh, it sprang up accidentally

amongst plants received from friends in the vicinity of

Calcutta ; of its native place he was uncertain. Under

the name of J. tuberculata it was figured and described in

the Botanical Register in 1816, and it is there stated that

the plant was raised from seeds collected in the Calcutta

Botanic Garden, and sent by Sir Evan Nepean, it would

appear early in 1815, to Messrs. Whitley, Milne and Brame,

Nurserymen of King’s Road, Chelsea. Jacquin first met

with it in the Vienna University Botanic Garden, where,

he informs us, it was obtained amongst several unnamed

Chinese seeds received from England in 1814. The

species appears to have a wide distribution, but very

probably it is not a native in some of the localities from

which it is recorded. In India it is known from Simla,

Rohilcund and the Deccan Peninsula. It is also known

from Ceylon “in dry country, very rare,” and from

Java. There is no satisfactory evidence that it is

native in China and Australia, though these countries

are included in its range by various authorities. In

Tropical Africa it ranges from Nubia, Abyssinia, the

Egyptian Sudan, German East Africa to the Kwebe

Hills in Ngamiland, and Upingtonia in South-West

Tropical Africa. There is a very small-flowered speci-

men in the Kew Herbarium labelled, possibly incorrectly,

“C.B.S. Villette.” The material for the accompanying

figure was obtained from a plant raised from seeds

received in 1917 from Major Howard of Richmond, and

collected by him at Kilimatinde in German East Africa.

The flowers vary considerably in size as shown by the

plant cultivated at Kew, as well as by the dried speci-

mens, and forms with unusually large flowers have been

supposed to represent distinct species and have been

described as such. It is possible also that the colour

varies, for in one instance the flowers are said to be

white. The curious little pouches, sometimes very

conspicuous at the base of the outer sepals, appear to

differ in size and in some of the dried specimens are

scarcely noticeable. It is almost certain that J. saccata,

- Hallier f. (in Engl. Jahrb. vol. xxviii. p. 48), from German

East Africa, of which there is no specimen at Kew,

should also be referred to 7. dasysperma. At Kew the

species has been raised and flowered in a tropical house.

Description.—Herb, apparently annual, everywhere quite glabrous. Stems

twining, 6-8 ft. high or more, very slender, simple or sparingly branched, at

times tuberculate. Leaves petioled, wide cordate-ovate,.13-4 in. long and

broad, 3-sect with the main lobes more or less narrowed at the base, and the

central lobe 8-partite while the lateral are 2-3-partite, or at times pedate ; lobes

lanceolate, acute or acuminate, quite éntire, 2-8 in. long, }—3 in. wide; petioles

{2 in. long, occasionally with rudimentary leaves resembling stipules in their

axils. Peduncles axillary, 14-1} in. long, 1-3 (rarely 4)-flowered, with a few

minute bracts. Sepals 5, elliptic with rounded tips, 1-2 in. long, 3-1 in. wide,

their margins membranous, their bases outside with 1 or 2 small pouches or

spurs. Corolla salver-shaped, glabrous; tube 1-1} in. long, 1-2 in. wide about

the middle, narrowed at the base, pale purple throughout and deep purple at

the throat; limb flattened, somewhat 5-angled, 23-4 in. across, from straw-

colour to sulphur-yellow, with 5 narrow greenish bands. Stamens 5; filaments

pilose at the base; anthers oblong. Ovary nearly globose, glabrous, encircled

at the base by a narrow but stoutish disk; style filiform, included, longer than

the stamens; stigma 2-lobed. Capsule globose, glabrous, about 2 in. across,

2-celled. Seeds 2 to each cell, somewhat 3-gonous, about } in. long and broad,

densely villous, sometimes fringed with long hairs along the two outer angles.

The charming Rhododendron here figured was first met

with by Mr. G. Forrest on the western flank of the Shweli-

Salwin divide in south-western Yunnan in August, 1912,

at elevations of about 10,000 feet and was found again

by the same collector at similar elevations on open

rocky slopes in the following June. Described at

Edinburgh from specimens of the second gathering,

R. callimorphum is now in cultivation in various collec-

tions in this country and appears to be fairly hardy at

Caerhays Castle in Cornwall, whence Mr. J. C. Williams,

with whom alone it has yet flowered, supplied the

material for our plate ; also at the Sunningdale Nurseries

JanuaRy-Marcg, 1919,

where, as Mr. H. White informs us, it has more than

once experienced very severe frost, but has escaped with

only slight injury; and at Kew where an example which

has lived out of doors for five years is quite healthy.

_In cultivation it has so far grown into a compact shrub

about three feet high, bearing some outward resemblance

to R. campylocarpum, Hook. f., figured at t. 4968 of this

work; its nearest ally, however, is R. Souliei, Franch.,

described at t. 8622. Marked features of R. callimorphum

are its long petioles covered with red or blackish stalked

glands, and its nearly cordate ovate-orbicular leaves with

a distinct bloom on the underside. Occasionally one of

the uppermost leaves is considerably reduced in size and

spathulate in shape, while the petiole is widened and

winged. It is not clear that this is a frequent feature

in f. callimorphum; it arrests attention owing to its

rarity in species of Rhododendron proper, though it is of

common occurrence in the Azalea section of the genus.

It is perhaps too soon to predict the situation that will

best suit 4. callimorphum and lead to its attaining the

The Aloe now figured was first discovered at Zanzibar

by Sir John Kirk by whom it was presented to Kew. It

has grown satisfactorily in a sunny tropical house where

it flowers in the autumn and suckers rather freely. The

original plant flowered at Kew for the first time not in

autumn but in April, 1895, and when it was then

described by Mr. Baker it still had “laxly rosulate ”

leaves, but by 1901 it had developed a stem thirteen

inches high with scattered foliage. From the suckers

several independent plants have been raised and one of

these, which forms the subject of our plate, flowered at

Kew in October, 1916. One of the plants had by

October, 1918, developed two stems, eleven and thirteen

inches high respectively, with five basal offsets from one

to two inches in height. The stem is relatively slender,

and the naked portion is conspicuous on account of the

gradual increase in thickness from the base upwards.

Though erect or at least ascending in these cultivated

plants, the appearance of the stem suggests that in wild

ones it may be more or less prostrate, a suggestion

strengthened by the inclined position assumed by the

inflorescence. The leaves, which are remarkable for

their closely set silvery white spots, are relatively small

for the genus; their sheaths are rather long and com-

pletely encircle the stem. It is singular that since its

original discovery this species has not again been met

with in a wild state. In the division of the section to

which A. concinna belongs are included two other Aloes,

both nearly related to our plant, yet both readily dis-

tinguished from it by their flowers, for one of them,

A. squarresa, Baker, a Socotran Species, has a shorter

perianth, while the other, A. Dorotheae, Berger, a species

of German East Africa, has a longer perianth than

A. concinna. :

The material on which our figure of the pleasing

Primula now described has been based was received

from Sir F. W. Moore, by whom it had been grown at

the Royal Botanic Garden, Glasnevin, under the name

P. chasmophila, Balf. f., in April, 1918. It is a native of

Bhutan, where it was obtained by Mr. Cooper when

collecting on behalf of Mr. A. K. Bulley, Neston,

Cheshire, through whom the plant figured had reached

Glasnevin. Professor Balfour, to whom the plant owes

its name, has kindly informed us that Mr. Cooper’s

original material was all in fruit, and that although the

plant flowered in the Royal Botanic Garden, Edinburgh,

in 1917 the blossoms were mostly so imperfect as to

render it desirable to defer the preparation of a full

JaNuARY-Manrcu, 1919,

description. In Bhutan the species is met with in dry

sunny positions in rocky soil at about 16,000 feet above

sea-level. P. chasmophilais a member of the Soldanelloides

section of the genus, whereof there are several species in

the eastern Himalaya and Western China, most of them

characterised by their diminutive size and relatively

small leaves associated with large and conspicuous

flowers, though usually they enlarge considerably after

flowering. Perhaps the extreme of this condition is met

with in P. uniflora, Klatt, a Sikkim species in which the

leaves are remarkably small while there is but a single

large flower. The nearest allies of P. chasmophila are

the Chinese P. spicata, Franch., and the Himalayan

P. Wattii, King.

The name Bulbophyllum robustum was originally used

to designate a species based on specimens preserved in

the herbarium at Kew which had been collected by the

Rev. R. Baron in the Central District of Madagascar.

In 1914, a living plant of a Madagascar Bulbophyllum was

presented to Kew by Sir F. W. Moore, Royal Botanic

Garden, Glasnevin, and on flowering proved to be

identical with the species discovered by Mr. Baron more

than twenty years earlier. The species belongs to a

somewhat small group of Bulbophylla in which the rachis

of the inflorescence is clavately thickened. The shortly

pedicelled individual flowers are tightly adpressed to the

rachis, and are considerably dilated laterally, while the

fleshy lip is immersed in a cavity formed by the united

lateral sepals, the margins of these being denticulate.

The nearest ally of B. robustum is B. crenulatum, Rolfe, —

work. Our plant differs from 2. crenulatum in its stouter

habit, its larger flowers and in the entire in place of

denticulate angles of the ovary. The plant is grown in

a basket suspended from the roof of a tropical house at

Kew, and thrives well under the treatment suitable for

other tropical species of the genus. It flowered at Kew

in May, 1917, when the figure now published was pre-

pared.

Description.—Herb, epiphytic; rhizome creeping, stout, tightly clothed

with ovate acute imbricate sheaths. Pseudobulbs sharply 4-angled, oblong,

3-23 in. long, $-$ in. wide, 2-foliate. Leaves elliptic-oblong, rather blunt,

Protea longifolia, the subject of our plate, has had

Holland, on the boundary of the ‘Stellenbosch and

Caledon divisions of Cape Colony. The field-notes at his

disposal enabled him to state that there it is rare, grows

on mountain-slopes, has wide-spreading roots, a trunk

about as thick as one’s arm, which branches about

JanuaRy-Marcg, 1919,

eighteen inches above the soil-level and attains a height,

with the branches, of some three feet. Burchell, who

collected it nearly a century later in the Donderhoek

Mountains near Villersdorp in northern Caledon, found it

to be there very common, reaching a height of five to

seven feet and resembling closely P. mellifera, Thunb.,

a native of the Coast Region of South Africa. The area

occupied by P. longifolia covers practically the whole of

the Caledon division and, if we include the form with

smaller leaves and heads, which Mr. Phillips separates as

var. minor, the species extends into the adjoining portion

of the Bredasdorp division. Whether it were introduced

in the time of Boerhaave or not, we know that towards

the close of the XVIII. Century it was raised at Schén-

brunn, from seeds sent or brought there probably by the

Austrian collector Scholl. Messrs. Lee and Kennedy, of

Hammersmith, received from Schénbrunn a plant or

plants which flowered in their nursery early in 1801,

and were figured by Andrews as P. longifolia nigra in

the “Repository.” But the same firm seem to have

obtained, also from Schénbrunn, other specimens which

likewise flowered in 1801 and were figured by Andrews

as P. longifolia ferruginoso-purpurea. About the same

time Hibbert had yet another specimen, likewise sent

from Schénbrunn, which Andrews described and figured

as P. longifolia, var. cono turbinato. But while Andrews

was satisfied that all three were forms or varieties of

P. longifolia, Sweet regarded them as distinct species

which he named P. longifolia, P. ligulaefolia and P, um-

bonalis respectively. A fourth figure purporting to

represent P. longifolia was published in the ‘* Botanical

one belonging to Messrs. Lee and Kennedy ; this time,

however, it was one introduced by Masson in 1790.

Sweet accepted Masson’s plant as true P. longifolia, but

Phillips, relying on certain differences exhibited in t. 47

of the “ Register,” has treated it as the basis cf a dis-

tinct species, P. ignota. In the ‘Flora Capensis”’

P. ligulaefolia and P. umbonalis are similarly recognised.

As no specimens of P. ignota, ligulaefolia or umbonalis

appear to have been preserved when their respective

plates were published, this course is possibly safer than

the alternative one of including all three under P. lonyi-

folia. But while there is no conclusive evidence to

justify the reduction of the three species proposed or

accepted by Sweet and Phillips, it has to be remarked

that the appearance of the flower-heads in the plant now

figured suggests that these heads do not develop per-

fectly and normally in our relatively sunless climate.

This in turn raises the question whether those differences

in the shape of the centre of the head, the length of the

_ perianth-arms, and the colouring of the involucral bracts

on which the separation of P. ignota, P. ligulaefolia and

P. umbonalis from P. longifolia depends, may not be fully

explained by the adverse conditions with which any

Protea has to contend when grown in this country. The

plant now figured was raised at Kew from seed collected

in the Caledon division by Miss M. Mason, to whom the

establishment is indebted for many interesting South

African plants. The seed was despatched from the Cape

in March, 1911; the plant depicted was cultivated in a

pot in a greenhouse where it has thriven well, and where

it flowered for the first time, at an unexpectedly early

age, in October, 1916.

Description.—Skrub, 8-7 ft. high, with finely tomentellous or almost

glabrous branches. Leaves narrow thong-shaped, blunt or somewhat acute,

gradually narrowed to the base, 3-7 in. long, }-2 in. wide, glabrous, nerves

pennate, visible only above. Flower-heads sessile, 4-6 in. long, about 4 in.

across; involucral bracts 9-10-seriate, glabrous, the outermost ovate or ovate-

oblong, obtuse, green, with often dark apical spots, the inner with a lanceolate

blade passing gradually into a claw and approaching or equalling the length of

the flowers. Perianth with a sheath 2 in. in length, dilated and 3-keeled at

the base, at first pubescent below, but ultimately glabrous; lip rather more

than 2 in. long, somewhat villous with usually white hairs except on the back,

their filaments very short; anthers linear, over } in. long, with shortly sharply

acuminate ovate-lanceolate glands at the tip; sterile stamen with a filiform

filament and a linear glandless anther. Ovary } in. long, densely rusty-

pressed base which is swollen on the ventral face; stigma }—} in. long, blunt,

distinctly kneed and curved.

It is now nearly eighty years since the Mexican Orchid

here figured was first described by Professor Lindley.

The original plant flowered in the collection of Mr. John

Rogers, junior, Vine Lodge, Sevenoaks, who had imported

the bulb. Mr. Rogers, who called Professor Lindley’s

attention to the character of the leaf-sheaths, remarked

that the innermost one, which surmounts the bulb, is

about eight inches high, and two to three inches in

diameter at the base, but only three-quarters of an inch

wide at the throat, translucent or semi-transparent and

containing about a third of a pint of water. The pitcher

is generally full, all the rain and dew on the leaves being

January-Marcy, 1919.

“

entire, and resembles a Florence flask in shape, being

conducted into it; this water appears to be absorbed by ©

the plant because if not replenished it disappears more

rapidly than evaporation would account for. Lindley

at a later date reduced his Govenia lagenophora to his

G, utriculata, a West Indian species, first described by

Swartz as Cymbidium utriculatum, but it is now known

that the Mexican and the West Indian plants are very

distinct and easily discriminated by the features men-

tioned by Mr. Rolfe. The original specimen of G. layeno-

phora does not seem to have been preserved, but the

letter from Mr. Rogers, accompanied by a sketch, is in

the Lindley herbarium, and at a still later date Professor

Lindley identified dried specimens collected by Hartweg

on the Monte de la Virgin as being identical with

Mr. Rogers’ plant. Since then the species seems to

have remained unknown until, in September. 1907,

Mr. Juan Balme, of Hijo, Mexico, sent a sketch of an

orchid, collected in the State of Vera Cruz, along with a

living bulb. The latter produced flowers in the Kew

collection in 1908, and at last enabled the confusion

between G. lagenophora and G. utriculata to be settled.

Mr. Balme’s plant has been grown in a warm house, and

is given an abundant supply of water except when the

Deutzia compacta was sent to Kew by the late

Mr. Maurice L. de Vilmorin in 1912, under the number

4377. It was received with a batch of Chinese plants, but

with no precise information as to the particular district

in China from which it had been introduced, or by whom

its introduction had been effected. It flowered at Kew

in July, 1913, when the accompanying figure was pre-

ed. At the same time flowering specimens were

received from Glasnevin, gathered from a plant which had

been presented to that establishment by Mr. de Vilmorin

also. The Kew plant is now about 4 ft. high, bushy,

and evidently very hardy. It is about the latest of the

Deutzias to open its flowers, and this not only adds to

its value as blossoming at a season when shrubs in flower

January—Marcg, 1919, :

are becoming scarce, but also enables it to escape the

late frosts which, at Kew at any rate, almost every year

ruin the display of most of the species. Its flowers are

pretty and distinct in their compact arrangement, their

smali size and large numbers, characters which dis-

tinguish it from D. rubens, Rehder. The Deutzias enjoy

a good loamy soil and abundant sunshine, and are easily

increased by means of cuttings put in in July.

The charming little Primula here figured was raised at

Kew from seeds collected by Mr. R. E. Cooper in Bhutan

in the Eastern Himalaya for Messrs. Bees, Limited, by

whom their supply was shared with this establishment

in 1915. The species, which was for the first time

described as P. tibetica by Sir George Watt in 1882, is a

native of alpine Sikkim and Bhutan at elevations of

16-17,000 feet above sea-level, and of the adjacent

provinces of south-eastern Tibet. It was originally

discovered by Sir J. D. Hooker, now seventy years ago,

on the Sikkim frontier of Tibet. It bears a rather close

resemblance to the more northern P. sibirica, Jacq., in

which species, however, the scape is usually much longer

and stouter, while the pedicels are shorter and the.

calyx-lobes have a fringe of minute glandular hairs that

is absent from P. tibetica, Distinctive features of this

Himalayan species are the pronounced yellow “ eye’? and

the gibbous bracts. At Kew P. tibetica has proved

hardy and has thriven well in the Rock-garden, but like

so many other members of the genus it proves in culti-

vation to be monocarpic and dies after flowering and

ripening its seeds.

The striking Orchid here figured is one of the largest

flowered members of the genus Liparis. It is a native

of the island of Formosa where it was first discovered,

over twenty years ago, on Liko Hill, near Tamsui, by

Mr. H. B. Morse, of the Chinese Consular Service. The

upper portion of the raceme of Mr. Morse’s original

specimen, which was communicated to Kew by Professor

A. Henry, had been lost; a single flower, however,

remained attached to the base of the inflorescence, and

thus admitted of the preparation of a description of the

species, as L. macrantha. The plant was met with again

by Mr. H. J. Elwes in the low country near Taikow in

Formosa, and a living specimen brought by him to

England flowered for the first time in his collection at

Colesborne, Cheltenham, in February, 1916. From this

plant, which was then presented to Kew by Mr. Elwes,

Aprit-JuNE, 1919,

the plate now given has been prepared. The species

belongs to the section Molliaefoliae, and is a striking

plant on account of its large undulate leaves, its long

raceme of vinous-purple flowers, and its large lip which

is strongly toothed on the margin. At Kew L. macrantha

has thriven well in a tropical Orchid House under the

conditions and treatment suitable for Indian species of

Calanthe.

Descriprion.—Herb, terrestrial. Stem erect, rather stout, 4-6 in. high.

Leaves petioled, spreading or recurved, ovate-elliptic or broadly elliptic,

subacute or shortly acuminate, undulate, plicate, membranous, 4-6} in. long,

Of the genus Pyrus as conceived by Linnaeus and

adopted by Bentham and Hooker, the section Malus, or

the crabs, is poorly represented on the continent of

North America, some four or five species only being

found there ; the pears (Pyrophorum) are not represented

at all. Malus rivularis is the only crab found west of

Aprit—J tye, 1919, oe

the Rocky Mountains where, however, it extends over

many degrees of latitude, reaching from Alaska through

British Columbia, Oregon and Washington to California.

It belongs to the same group of crabs as M. Toringo,

Sieb. and M. Sargentii, Rehd., figured at t. 8757 of this

work, all characterised by the calyx falling away from

the apex of the fruit. From both the other species

M. rivularis is well distinguished by its ellipsoid fruits

and by the shorter lobes of the calyx as compared with

the calyx-tube. The fruit has a rather pleasant acid

flavour and is variable in size and colour. On our

plant, which was obtained for Kew from a continental

nursery in 1905, they appear to be larger and more

cylindrical than is usual. According to Sargent this

crab in a wild state affects moist situations where the

soil is deep and rich, often forming in such places large

impenetrable thickets. Archibald Menzies, the surgeon

and botanist attached to Vancouver’s expedition of

"survey, appears to have been the first European scientific

observer to find it, which he did about 1793. David

Douglas collected it some thirty years later, and it is

said by Loudon to have been introduced in 1836. It

has never been much cultivated in English gardens,

although it is very hardy and grows vigorously, and is

quite attractive when laden with its distinct and hand-

some fruits.

Description.—Tree, 15-30, sometimes 40 ft. high, the trunk 1-13 ft. in

diameter; young shoots clothed with grey hairs at first, becoming glabrous;

purplish-brown the second season. Leaves deciduous, ovate to ovate-lanceolate,

acute or acuminate, usually rounded or occasionally cuneate at the base,

sometimes obscurely lobed above the middle, finely and sharply serrate ;

13-33 in. long, 3-13 in. wide; dark dull green, and at first puberulous above,

finally glabrous ; paler and pubescent beneath ; petiole }-14 in. long, pubescent.

Flowers 3-1 in. wide, terminal or produced in the axils of the terminal leaves,

8-12 forming a corymb 2-3 in. wide, expanding in May. Calyx-tube obconic,

pubescent; lobes 5, lanceolate, ;3: in. long, slightly pubescent or glabrous

outside, thickly covered with pale grey wool within. Petals 5, orbicular with

a short claw and a few jagged teeth near the base, % in. long, creamy white.

Stamens 16-20; filaments glabrous, flattened. Styles 2-5 (usually 3) joined

near the base, glabrous. Wruit ovoid-oblong, pendulous, }—3 in. long, 3 in.

wide, glabrous, ripe in October and then yellow tinged with pink on the sunny

side, greenish in the shade, the calyx falling away and leaving a sinall pit at

the apex; peduncles slender, 1-1} in, long, glabrescent. Seeds +; in. long,

The genus Wittia is singular among the Cactaceae in

combining with the habit of Phyllocactus and Epiphyllum

the character of possessing very small flowers. It was

originally described by Dr. K. Schumann in 1911, and

was based on a Peruvian species which he named

W. amazonica; the plant in question was collected by

Mr. Ule near Lacaitia and also near Tarapoto. The

description of W. amazonica had just appeared when in

October, 1911, a second species was met with by

Mr. H. Pittier on the mountains above Chapo in Panama.

This plant flowered at Washington some months after-

wards and in due course was described and figured by

Messrs. Britton and Rose as Ji’. panamensis. In 1914 |

a plant of W. panamensis was presented to the Kew

collection by Mr. D. Fairchild, Department of Agriculture,

Washington. This plant, which has thriven well in the

Succulent House at Kew, flowered there in May, 1917,

Aprit-JuNE, 1919, : .

when our figure was prepared. Since then Britton and

Rose have been able to describe, as JW. costaricensis,

yet another species, also collected by Pittier, but on

this occasion on the west coast of Costa Rica. Britton

and Rose also remark that Wéittia is a strange genus,

having stems resembling those of Epiphyllum and

Rhipsalis, with flowers very different from those of

either of these genera.

Description.—Herb, with succulent, sparingly branched, elongated, flattened

stems, which are leafy in appearance, are distantly crenate along the margin,

exhibit a stout median rib, and attain a width of 13-13in. Flowers axillary,

borne at the bases of the crenations, 1-1} in. long, deep purple. Calyx with a

The Honeysuckle here figured was originally discovered

by the late Abbé Delavay in South-Western China, and

was at first regarded by the late Mr. Franchet as a

distinct species which he named in compliment to its

distinguished collector. The more ample material now

available has, however, led Mr. Rehder to think that it

is only a glabrescent variety of Lonicera similis, Hemsl.

The plant from which our figure has been prepared was

presented to Kew in 1910 by the late Mr. M. L. de

Vilmorin, who had raised plants at Les Barres from seeds

received from South-Western China in 1901, some of

which flowered for the first time in 1904. Among the

nearer allies of L. similis, var. Delavayi, are L. macrantha,

Wall., from which it differs in having a longer, glabrous

corolla-tube, and L. longijlora, DC., from which it is

Aprit—JuNE, 1919,

easily distinguished by the leaves being grey-tomentellous

beneath and cordate at the base. All three belong to

the group Longiflorae of the section defined as Nintooa by

DeCandolle, within the subgenus Chamaecerasus. A

climber of vigorous growth, L. similis, var. Delavayi, is

very hardy and, being evergreen, promises to be a useful

addition to a group of shrubs rather scanty in outdoor

collections—the hardy evergreen climbers. Another

useful quality of our plant is the circumstance that it

flowers as late as August. It thrives very well in a

loamy soil and can be increased by late summer cuttings.

Description.—Shrub, climbing, evergreen; branches terete, glabrous.

Leaves wide-lanceolate, acute at the apex and cordate at the base, up to 23 in.

long and 2 in. wide, entire, upper surface glabrous, with raised dots, bright green,

The pleasing Primula here figured is a native of the

Eastern Himalaya, belonging to the Capitatae section of

the genus, from all other members of which it is dis-

tinguished by its doubly and rather coarsely toothed

membranous leaves which are adpressed _ strigose-

pubescent on both surfaces. It has been regarded by

Sir George Watt as the East Himalayan representative

of the well-known P. farinosa, Linn., which extends from

North America through Europe to Western Tibet. Our

species was first discovered on Alpine slopes in Sikkim,

at elevations of 13,000 feet, by one of the native

collectors employed by Sir George King, who, recognising

it as distinct, gave it the name P. bellidifolia, The plant

Aprit-JunE, 1919, ;

from which our figure has been prepared was one of a

number raised from seed presented to Kew in 1915 by

Messrs. Bees, Limited, for whom it had been collected in

Alpine Bhutan in 1914 by Mr. R. E. Cooper. The species

has thriven well at Kew, and plants put out of doors in

the Rock Garden flowered freely in May. Other plants

grown in pots in a cool frame flowered equally freely and

were exhibited in the Alpine House. Like its allies

P. farinosa, Linn., and P. denticulata, Sm., between which

it is in general features intermediate, P. bellidifolia has

proved monocarpic. The plants in this instance, how-

ever, though behaving as if quite hardy, unfortunately

died after flowering without ripening their seed.

Drscription.—Herb, up to 10 in. high. Leaves all radical, spathulate-

obovate, tip rounded, base cuneate then curvately narrowed into the somewhat

winged petiole, 1}-3 in. long, 2-11 in. wide, when dry membranous, margin

The Ahododendron now figured was first met with by

the Abbé Delavay, between 1883 and 1885, on the

mountain Tsang-chan, overlooking Tali in Yunnan, at

about 6,700 feet above sea-level, and was described by

Mr. Franchet in 1886 as 2. oleifolium. It was met with

again in 1906 by Mr. George Forrest, on the eastern

flank of the Tali range, Lat. 25° 40’ N., in open alpine

pastures at altitudes of 8—10,000 feet, as a dwarf shrublet

a foot. to two and a half feet high, with blossoms varying

in colour from white to pale rose. The plant from which

our illustration was made was raised at Kew under glass,

from seed obtained from Messrs. Bees, Limited, early in

1915. It flowered in May, 1917, when only two years old,

Aprit-June, 1919, .

thus sharing with /2. racemosum, Franch., another Yunnan

species already familiar owing to its suitability for culti-

vation in masses in flower-beds, and already figured at

t. 7301 of this work, the characteristic of producing its

blossoms at a very early stage of its career. Another

feature which £. oleifolium shares with its near ally

ft. racemosum is that rare character in Rhododendrons,

the production of solitary axillary flowers. To this

peculiarity is due the distinctive habit of these two

species; their leaf-bearing buds as a consequence are

always terminal, and a primary shoot, having once

flowered, never branches again save when it has been

injured. Although the particular plant of R. oleifolium

now depicted was raised under the protection of a cold

frame we believe the species may prove hardy, for other

plants, grown out of doors, have shown no signs of

tenderness as yet, though the species has not been

sufficiently long in cultivation to admit of our judging

how resistant to English weather conditions it may be

as compared with its better known ally, 2. racemosum.

From that species R. oleifolium is readily distinguished

by the longer and narrower leaves, and especially by the

presence of a soft hairy indumentum on the outside of

the corolla-tube as well as by the lepidote style.

Descripti0n.— Shrub of small size, reaching a height of 23 ft., laxly branched

upwards; stem yellowish-grey, glabrous; shoots of the second season rusty,

finely lepidote; new shoots densely lepidote. Leaves lax, lanceolate or oblong-

lanceolate, acute, narrowed or somewhat rounded at the base, 1-2} in. long,

378 in. wide, papery, at first lepidote, but soon glabrous and dull green above,

somewhat glaucous and lepidote beneath, the scales small and fleshy and

rather further than their own breadth apart; midrib sunk above, raised

beneath ; lateral nerves 8-10 along each side, raised beneath ; petiole 4-1 in.

long, without scales. Flowers solitary or in pairs, axillary; flower-buds narrow

ellipsoid, about 2 in. long before the flowers open, their scales brown, without

scales outside, the uppermost finely ciliolate, pedicels very short and hardly

exserted from the scales, densely lepidote. Calyx 5-lobed; lobes ovate-

. triangular, blunt, 3, in. long, sparingly lepidote near the base outside. Corolla

rose-coloured, tubular, 1-11 in. long, 5-lobed; tube 2 in. long, about } in. wide

pubescent; lobes wide-ovate, rounded at the tip, about } in. long, densely

lepidote outside. Stamens 10, longer than the corolla-tube ; filaments flattened,

pubescent near the base, anthers in. long. Ovary 5-celled, densely lepidote ;

style about as long as the corolla, lepidote and sparingly pubescent near the

base, tipped by a large 5-lobulate stigma. Capsule 2 in. long, rusty-lepidote.

Calanthe tricarinata is an old and well-known Orchid,

which was first discovered by Wallich in Nepal in 1819.

Since then it has been met with by various collectors in

many other localities in the north-west Himalaya. In

the “‘ Flora of British India” its habitat is given as the

temperate Himalaya, at elevations of 5000-9000 feet,

from Kashmir to Nepal. Soon after this announcement,

which was made in 1890, the species was found in

Sikkim, by Pantling, at an elevation of 6000 feet, in the

Lachen valley. But it had already been reported by

es Maximowicz to occur in grassy woods near Lake Conoma,

=o in Japan, and it was from Japan that the species was

: first introduced to cultivation in this country. This

introduction was in a sense accidental; the species was

found among some plants of C. Textorii, Miq., imported

AprRIL~J UNE, 1919.

by Messrs. J. Veitch and Sons in 1879. Between the

time of its discovery in Japan and of its being met with

in Sikkim, Mr. A. Henry had collected C. ¢tricarinata in

the northern mountain forests of Yunnan at an elevation

of 7000 feet. In cultivation C. tricarinata thrives well

under the conditions suitable for other species of the

genus, such as C. Masuca, Lindl., figured at t. 4541 of

this work. The plant now figured flowered in April,

1916, in the collection of Mr. H. J. Elwes, at Colesborne

Park, Gloucestershire, and was afterwards presented by

Mr. Elwes to Kew. It is understood that this particular

plant was obtained by Mr. Elwes from Sikkim. In

spite of its wide distribution and of its introduction

forty years ago, C. ¢tricarinata has always been a rare

plant in cultivation. It has, however, been used as one

of the parents of a garden hybrid, C. //arryana, raised

by Messrs. Veitch, the other parent in this case being

C. Masuca.

Description.—Herb, terrestrial; pseudobulbs short, ovoid. Leaves 2-3,

The plant here figured was originally described as a

variety of Lonicera hispida, Pall., but the characters

given above seem to be sufficiently definite and constant

to separate it from that very variable species. Following

the classification of Rehder, this species, which he terms

L. chaetocarpa, is to be included in the Bracteatae group

recognised by Hooker and T. Thomson within the

section defined as Jsika by DeCandolle, and thus falls

within the subgenus which Linnaeus termed Chamae-

cerasus. The original specimens of L. chaetocarpa were

collected in Kansu, but the plant has since been met

with both in Szechuan and in Eastern Tibet. It was

introduced to cultivation by Mr. E. H. Wilson in 1904

when collecting in Western China for Messrs. Veitch, and

Aprit-J UNE, 1919.

the material from which our figure has been prepared was

taken from a plant purchased from that firm in 1913.

The Kew example is now a shrub about five feet high,

of neat, rounded habit, and is evidently perfectly

hardy. At Kew it is, indeed, regarded as one of the

best and most satisfactory of the newer shrubby honey-

suckles. It likes a good loamy soil and is easily

increased by means of cuttings put in sandy soil in

gentle heat during July and August. Its flowers open in

early June and are of a pleasing primrose yellow.

Description.—Shrub, compact in habit, about 5 ft. high; branches terete, —

the younger purplish, hirsute with spreading hairs. Leaves oblong-elliptic,

with an obtuse or sub-acute apex, rounded and often unequal at the base,

13-2 in. long, about 1 in. broad, entire, the upper surface bright green, more or

less hirsute, with the midrib and lateral nerves slightly impressed, the lower

The Desmodium now figured is a native of South-

western China first gathered over thirty years ago by

the Abbé Delavay, by whom it is reported to occur on

chalky hills near Lankong in Yunnan. It was first

described from material sent by Delavay to Paris. Later

it was met with by Mr. A. E. Pratt near Ta-chienlu in

Szechuan, and a few years ago it was found again by

Mr. G. Forrest on the eastern flanks of the Li-Kiang

Range in Yunnan at elevations of 9-10,000 feet above

the sea. The nearest ally of D. cinerascens is the North

Indian species D. tiliaefolium, G. Don, a species of which

we have as yet seen no Chinese example. The record of |

D. tiliaefolium as a native of China has been made in the

Aprit-JunE, 1919,

“Plantae Wilsonianae” (pars iv. p. 104); but the plant

so named appears to Mr. Hutchinson to be D. cinerascens

or some nearly allied species, rather than true D. tiliae-

folium, which has in India been associated with D. nutans,

Wall., and D. argenteum, Wall., but is considered by Mr.

Hutchinson to be distinct from both. From D. tiliae-

folium, as thus restricted, Mr. Hutchinson separates

D. cinerascens by its shorter petioles, more rounded

leaflets, persistent stipules and usually quite simple pilose

racemes. D. cinerascens appears to have been first raised

in Europe from Chinese seeds by the late Mr. M. L. de

Vilmorin in 1896. It was presented to the Kew collection

by him in 1907, and has proved to be quite hardy, being

now a bush three to four feet high. It does not flower

until late in the year, usually in October, and while this

adds to its value in places where the climate is sufficiently

dry and sunny to enable the flowers to develop fully,

in a locality like Kew they are apt to decay prematurely

through lack of sunshine and excessive humidity. For

the same reason seed can rarely ripen, and the plant

must be increased by late summer cuttings. The

material for our plate we owe to Miss Willmott, in whose

collection at Warley Place plants raised from Chinese

seed collected by Mr. E. H. Wilson have grown well.

This variety of the widely distributed Ipomoea Pes-

tigridis is a new introduction to cultivation. The Kew

plant which furnished the material for the figure was

raised from seeds received in February, 1917, from

Major Howard of Richmond, Surrey, who collected

them, and also those of J. dasysperma, Jacq., figured at

t. 8788 of-this work, at Kilimatinde in the district of

Ugogo, East Tropical Africa, near the railway connecting

Daressalam with Tabora. It had previously been found

Aprit-JuNE, 1919,

in other localities of the territory known as German

East Africa; it is also recorded from Somaliland and

British East Africa. Grown ina warm house, it flowered

while still quite a small plant in April, 1918, and, being

an annual, has since died. Typical /. Pes-tigridis ranges

throughout India, where it is said to be common, growing

in sandy soils; it also occurs in Ceylon, the Malay

Peninsula, Malay Islands, Polynesia, China, Mauritius,

and in many localities in Tropical East Africa, extending

from Kordofan in the north to the Zambesi in the south ;

it is represented in Angola by the variety strigosa, Hallier -

f. Though of little merit as a garden plant it has

appeared in cultivation from time to time, and is

recorded as having been first introduced in 1732, the

year of publication of Dillenius’s Hortus Elthamensis,

in which work (t. 318, fig. 411) it is figured as Volubilis

zeylanica, Pes-tigrinus dicta, Tt is also figured in Rheede’s

Hortus Malabaricus, vol. xi. t. 59, under the name of

Pulli-Schovadi. This Ipomoea belongs to the section

Cephalanthae, the species of which usually have rather

small flowers arranged in dense bracteate heads, with

alee herbaceous sepals more or less resembling the

racts.

Description.—Herb, annual, everywhere densely beset with long yellow

stiff hairs. Stem twining, slender, 6 ft. long or longer. Leaves stalked,

palmately 5-9-partite, 3-4} in. wide with rounded sinuses ; lobes lanceolate or

ovate-lanceolate, acute or more or less acuminate, quite entire, 14-3 in. long,

3-12 in. wide; petiole 2-4 in. long. Peduncles axillary, usually 2-53 in.

long, but occasionally only 2-1} in. long, bearing 2-5-flowered blossom-heads.

Bracts lorate or linear, acuminate, 3-1} in. long, 2-1 in. wide. Sepals ovate-

lanceolate, acuminate, 3-2 in. long, up to } in. wide. Corolla white with the

tube purple outside and the throat violet within; tube funnel-shaped, j—1 in.

long; _limb spreading, reaching 2} in. in breadth, shortly 5-lobed; lobes

emarginate. Stamens included ; of unequal length ; filaments bearded at the

base ; anthers oblong, s in. in length. Ovary ovoid, glabrous, zi; in. long,

surrounded at the base by the entire cup-shaped disk ; style filiform, about } in.

long, shorter than the longest of the stamens; stigma capitate, papillose.

The Disporum now figured is a native of Western

Hupeh, where it was first met with by Mr. E. H. Wilson.

The plant from which our plate has been prepared

flowered in 1917 in the collection of Miss E. A. Willmott,

Warley Place, where seeds obtained by Wilson had been

received from the Arnold Arboretum. Only one of these

seeds, we learn from Miss Wilmott, germinated in her

garden. The resulting plant throve well in good sandy

loam in a sheltered and partially shaded border with a

south-western exposure. A few flowers only were

produced during the first season after planting out;

since then, however, the plant has flowered freely each

year and has ripened seeds well, thus admitting of ready

propagation. Care has, however, to be taken to protect

the ripening fruits against attack by birds. The genus

Disporum was based by Salisbury in 1812 on a Chinese

plant, Disporum pullum, which had been already de-

Aprit-Jounz, 1919,

scribed at t. 916 of the “ Botanical Magazine’ as Uvularia

chinensis, Ker-Gawl., and the plant now figured, though it

differs sufficiently from the original type of D. pullum

to deserve a separate plate, hardly merits, in the present

state of our knowledge, the status of a distinct species.

Sir Joseph Hooker has referred in the “ Flora of British

India’ to the difficulty met with in the discrimination,

from herbarium material alone, of the various forms that

occur in the genus Disporum. In the case of those forms

generally included in D. pullum this difficulty is especially

great, and this species, as now understood, contains a

number of more or less distinct states differing from each

other in the width and degree of pubescence of the

leaves, the length of the peduncle, the size of the flower,

and the colour of the perianth-segments which varies

from white to deep-purple. In the form here figured

there is another marked distinction; the perianth-

segments, instead of being straight, at length spread

stellately towards their tips. For this reason it is now

provisionally accorded the rank of a distinct variety,

whose name, brunnea, is derived from the circumstance

that these segments are of the purplish-brown colour

indicated at n. 72 of the “Code des Couleurs ”’ of Messrs.

Klincksieck and Valette.

Description.—Herb, with a glabrous, branching stem. Leaves lanceolate,

acuminate, 2} in. long, 2-2 in, wide, rounded at the base, glabrous above,

puberulous beneath and along the margin ; lateral nerves 7-9 on each side the

midrib, 2 sometimes 8 of them resembling the central nerve ; petiole sheathing,

2 in, long. Peduncle } in. long, puberulous, 3-5-flowered ; pedicels nodding,

about 1 in, long, with distinct longitudinal papillose lines. Perianth composed

with the margin of the upper two-thirds finely denticulate, spreading at the

tip, purplish-brown, 14 in. long,3in. wide. Filaments subulate, pale green,

The red Belvidere, also termed the Summer Cypress

or Mock Cypress, here figured, is generally accepted as

a cultivated condition of Kochia scoparia, Schrad., a

Chenopodiaceous plant which extends from temperate

JULY-SEPTEMBER, 1919.

Asia westward through central and south-western Russia

to Hungary. Throughout Germany as far as the Nether-

lands and from Central Europe southwards into the

Balkan peninsula, Italy and southern France, it also

occurs not infrequently as an alien. The name scoparia,

long associated with the species, reflects the fact that

throughout southern Europe the dry plant is used for

making brooms. The genuine Kochia scoparia has been

known in English gardens at least since the close of the

sixteenth century; it was figured by Gerarde in 1597

as the Bushie or Besome Tode-flax, but he was already

acquainted with the popular Italian name Belvidere,

which during the seventeenth century appears to have

been the term mostly used in English and French

gardens. It is clear from Gerarde’s account that the

form of the plant known to him did not change in colour

from green to red during the autumn, and, indeed, there

is no evidence that during the next three centuries any

form of K. scoparia exhibiting this phenomenon was

known to gardeners. Nor is there any indication that

during the sixteenth and seventeenth centuries the form

of the Belvidere with narrower leaves figured in our plate

was in cultivation in this country. We do not till 1759

find any evidence that suggests the existence of

K. scoparia, forma trichophila, in British gardens. This

evidence comes from Scotland, and the seed of the

narrow-leaved form appears to have arrived there from

Holland as Belvidere, under which name it appears in

a Haarlem seed-list of 1754. We learn from Miller’s

Gardeners’ Dictionary” of 1768 that the narrow-

leaved form was in English gardens, but we find no

allusion to any save a green Belvidere throughout the

eighteenth century. With the establishment of the form

with nearly filiform leaves just after the middle of that

century, the cultivation of the true K. scoparia appears

to have been abandoned. During the later half of the

nineteenth century the same became very nearly the

case as regards the green narrow-leaved form, its culti-

vation being continued only in large establishments

like that at Kew. At the close of the century, however,

interest in this old-fashioned plant became resuscitated

owing to the discovery in or shortly before 1898 of the

red Belvidere, which we now figure. In that year a

farmer from Alleghany, Pennsylvania, visiting Riverton,

New Jersey, handed to Mr. J. W. E. Tracy some seed of

this plant with the information that it had been collected

from a wild specimen found growing in the woods near

Alleghany. The seed was made over to Mr. Henry A.

Dreer, who grew it, but did not, however, take the plant_

up. In the following year seed was made over to Mr.

Burpee who gave the plant a trial, and placed it in his

catalogue for the first time in 1900. Mr. A. J. Pieters,

of Washington, to whom horticulture is obliged for this

information, remarked in 1906 that after having grown

the plant for four years, he had found it constant as

regards the change of colour which is its most striking

characteristic, but that it is apt, when checked in its

growth, to revert to the opener habit which marks the

true K. scoparia. It is interesting to note that shortly

after the record of this experience by Mr. Pieters,

Professor Beck was in a position to describe for the first

time in Reichenbach’s “‘Icones” (vol. xxiv. p. 154:

1908) a blood-red wild form as K. scoparia, forma

sanguinea. For the introduction of the red Belvidere

with filiform leaves to this country we are indebted to

Messrs. Cannell and Sons, Swanley, who first brought

it to notice in the autumn of 1901. Although the fact

is not on record, it is probable that their seed may have

come from the United States. The red Belvidere is now

somewhat extensively used as a summer bedding plant

in gardens, a purpose for which it is well suited. It

comes true to seed, and the change in colour from bright

green to magenta red takes place somewhat suddenly

in autumn. The change appears to mark a stage in

ripening, and to be unconnected with the climatic con-

ditions encountered by the plant whether in this country

or in North America.

Descrietion.—Herb, annual, polygamous, much branched from the base,

very leafy; crown globose, oblong or conic-pyramidal, 14-5 ft. in height ;

branches and branchlets virgate, erect, at first thinly pubescent, soon nearly

glabrous, though often laxly woolly towards the top and especially at the nodes.

Leaves narrow linear or the uppermost nearly filiform, acute, the longest over

din. long, Lin. or less wide, glabrous or the uppermost somewhat ciliate, all

white-punctate. Flowers in threes or pairs, or solitary, sessile in the axils of the

upper leaves, often surrounded at the base with loose wool, some female, some

2-sexual. Perianth urceolate, 5-lobed, membranous, the female rather depressed,

glabrous except the lobes, which are ciliolate, inflexed and hood-like, somewhat

apiculate and traversed along the back by a green blunt keel, when fipe little

altered save that the keel is occasionally enlarged in the middle into a thick

transverse wing. Anthers purple. Ovary ovoid; style very short; stigmas 2.

Fruit depressed, lenticular. Pericarp and testa membranous. Embryo horizontal.

The interesting Odontoglosswm now figured is a native

of Ecuador, where it was first discovered about eighty

years ago by Mr. T. Hartweg, when collecting plants for

the Royal Horticultural Society of London. ‘The locality

of the original specimens was Mount Paccha, near Loxa,

on the western slopes of the Andes opposite the Gulf

of Guayaquil. For many years this species, which

Lindley had described as Q. cristatum, was only known

from the original herbarium specimens, but in 1847

living plants of an Odontoglossum, collected in the Loxa

district by Mr. G. Wallis, were sent to the horticultural

establishment of Mr. Linden at Brussels; these plants,

on flowering, were recognised as identical with Hartweg’s

one. At a later date the late Mr. Consul Lehmann

JuLy-SEPTEMBER, 1919.

obtained other specimens of this species in Ecuador, in

the forests of Pacayurcu, above Zaruma, also above

Ayabamba and Paccha, at from 4,500-6,800 feet above

sea-level. Though never a common species in cultiva-

tion, it is usually present in representative collections

of Orchidaceous plants. The figure here given has been

prepared from an example which flowered in the Royal

Botanic Garden, Glasnevin, in March, 1917.

This plant, Sir F. Moore informs us, was presented to

the Glasnevin collection by Sir Jeremiah Colman, in 1908,

who had grown it at Gatton Park as an unnamed Odonto-

glossum. The species thrives under the treatment for

cool-house orchids, a minimum night temperature of

50° F. in winter, with cool airy conditions in summer.

A more slender plant in every way than the familiar

O. crispum, Lindl., from New Grenada, O. cristatum

makes finer and more delicate roots, so that care should

be taken that the potting material is not too coarse.

There is at Glasnevin another example of O. cristatum,

obtained in 1893 from Mr. Cowan, of Gateacre, which

was identified at Kew on its first flowering in 1894.

The nearest ally of O. cristatum is O. Hallii, Lindl.,

another Ecuador Odontoglossum, which has been already

figured at t. 6237 of this work.

Description.—Herb, epiphytic. Pseudobulbs elliptic- or ovate-oblong, com-

pressed, slightly striate, 24-2 in. long, 3-14 in. wide, 2-foliate at the apex,

4-foliate at the base. Leaves lorate, slightly curved, rather acute, 6-9 in. long,

%2 in. wide, conduplicate below. Scapes axillary, curved, 10-14 in. long ;

racemes laxly many-flowered ; bracts ovate-oblong, rather acute, conduplicate,

3-2 in. long, concave ; pedicels about Zin. long. Flowers showy. Sepals and

petals spreading, elliptic-lanceolate, acuminate, 1-11 in. long, yellow with brown

spots and flushed with brown towards the tips. Lip clawed ; claw erect, narrow,

about in. long; limb spreading, ovate or somewhat pandurately ovate, acute

or acuminate, irregularly fimbriate, about 2in. long, with a large palmately

lobed basal crest. Column curved, nearly 3 in. long ; wings rounded, irregularly

fimbriate ; pollinia 2, pyriform ; stipe linear-oblong, somewhat incurved ; gland

oblong,

The plant from which our plate of <Abelia longiflora

has been prepared was presented to the Kew collection

by Sir John Ross of Bladensburg, in 1915. The species

is a native of China, and the specimens on which the

original description of Dr. Rehder was based were col-

lected in the district of Ichang, in the province of Hupeh,

by Mr. A. Henry. These original specimens differ in

certain minor particulars from the cultivated plant here

represented. The wild plant has all the twigs, young

and old, nearly or quite glabrous, whereas in our plant

the young twigs are densely clothed with short spreading

hairs. The corolla in the original specimens collected

by Henry are somewhat larger than in the plant received

JULY-SEPTEMBER, 1919.

at Kew from the collection at Rostrevor. The nearest

ally of A. longituba is A. uniflora, R.Br., another Chinese

species figured at t. 4694 of this work. Both species

have been placed by Rehder in the section Huabelia

and in Graebner’s sub-section Uniflorae. There is, indeed,

room for doubt as to whether A. longituba be really more

than a variety of Brown’s species. From the horti-

cultural point of view, however, A. longituba is suffi-

ciently distinct from the older species to warrant the

publication of a special plate. At present the Kew plant

is a dwarf shrub which flowers most copiously during the

latter part of the summer, a circumstance that makes

it a very welcome addition to cultivated hardy shrubs.

It is perfectly hardy, grows well in loamy soil, and is

easily propagated by means of cuttings put in gentle

heat in July or August.

Description.—Shrub, branches ‘slender, the older twigs dark and glabrous or

slightly puberulous, the younger purple and densely puberulous. Leaves ovate,

elliptic-ovate or oblong-lanceolate with a rather obtuse and mucronulate apex,

the base more or less cuneate, lin. long, }-3 in. wide, margin entire or

slightly serrulate, upper surface bright green, glabrous except for the ciliate

margins, lower pale, white-villose along the mid-rib, especially in the lower

part ; petioles up to iin. long, slightly hirsute. Peduncles 1-flowered, axillary,

situated near the ends of short branches, in. long, with 2 subulate-linear

ciliolate bracts in the middle and 4 ovate ciliolate bracteoles at the apex.

Receptacle (ovary) cylindric, about 4 in. long, 2 in. in diameter, slightly

puberulous, Sepals 2, oblong-elliptic, obtuse, up to 2'in, long, } in. broad, slightly

ciliolate, nearly glabrous. Corolla infundibuliform, from nearly lin. to 11 in.

base, enlarged from the middle upwards, limb spreading, 5-lobed, lobes sub-

orbicular, } in. long and broad, minutely glandular-puberulous outside, throat

on the inside beset with long distinct hairs. Stamens 4, filaments nearly 2 in.

This fine Wistaria, Messrs. Rehder and Wilson have

pointed out, is readily distinguished among its congeners

by the persistent soft and short indumentum of the

leaves, by its comparatively short and very wide racemes,

its stout spreading velvety pedicels, its large flowers,

and its long subulate anterior calyx-teeth. When the

number and character of these distinguishing features

are considered it seems extraordinary that the right of

the Japanese W. venusta to be regarded as a species

apart has remained so long unrecognised. Jn addition

JuLY-SEPTEMBER, 1919.

to the citations which accompany our description, the

authors quoted supply others, which it is needless to

repeat here; it is sufficient to remark that it has been

confused more than once with the common W. sinensis,

Sweet, and the not unfamiliar W. brachybotrys, Sieb. &

Zuce. It was first seen in this country under the latter

name, in the Japanese section of the International

Horticultural Exhibition held at Chelsea in May, 1912,

and in the following year was acquired from a Yokohama

nursery for the Kew collection. According to Mr.

Wilson, W. venusta is cultivated here and there in temple

gardens in Japan as the “ Shira-fudzi,” or White

Wistaria ; but the colour of the flowers would appear to

vary, for a specimen collected by Mr. R. Oldham, “ wild

on hills near Nagasaki,” in 1863, which undoubtedly

belongs to this species, is noted by him as having bluish-

violet flowers. The plants exhibited in 1912 were

shown as shrubs grown in vases; in the Kew collection,

however, it thrives quite well in the open, and flowers

annually in May and June. It makes a very welcome

and beautiful addition to the popular group of hardy

flowering climbers and, like other members of the genus, ©

requires a good rich soil and the sunniest position

available. The flowers are frequently more or less

“* double.”

JuLY-SEPTEMBER, 1919,

Tris Reichenbachii is a native of the Balkan countries

from Bosnia, southern Hungary and Serbia, to eastern

Rumelia and southern Macedonia. The species was

originally described by Heuffel from specimens found in

the Hungarian Banat, growing on rocks by the Danube,

and from others gathered near Herkulesbad. It may be

regarded as the Balkan representative of the more

western species J. Chamavciris, Bert., a native of Italy

and southern France, from which J. Reichenbachii is

easily distinguished in the living state by the very

acutely keeled herbaceous spathes. While in reality an

extremely natural species, J. Reichenbachii is at the same

time characterised by extraordinary variability in size

of plant and colour of flowers. Owing to this variability

the plant has at times been misunderstood, hence the

unusually long list of synonyms. How pardonable this

misunderstanding is will be readily appreciated from an

examination of our figure. J. Reichenbachii has been

in cultivation in the Ivis collection at Kew since 1904,

when a supply of plants was acquired from Messrs. Haage

and Schmidt, Erfurt. Additional plants were presented

to Kew by the Hon. N. C. Rothschild in July, 1915;

these had been collected on the mountains near Conrova,

in Bulgaria. Yet other plants were presented to the

national collection by Lady Muriel Herbert in May, 1919 ;

these had come from Salonika. The plate now published

has been based, however, on other material; the form

with red-purple flowers was received from Miss D.

Blanchard, who had flowered it in her garden at Park-

stone, Dorset, in May, 1919—her plants having originally

been received from Macedonia; the form with greenish-

yellow flowers was sent by Lady Muriel Herbert in May,

1917—it was one of her plants from Salonika. At Kew,

1. Reichenbachii is quite hardy, and has flowered in an

open border. It prefers, however, a warm position

against a wall. Seeds are only sparingly produced, but it

is easily propagated by division of the rootstock, as in

most other species of the section to which it belongs.

Description.—Herb, with a rootstock 2in. thick. Leaves densely clustered,

ensate, more or less falcate, those of the sterile clumps at length usually 5-6 in.

long and {2 in. wide, but at times much longer and wider, those of the flowering |

stem shorter, glaucous-green, smooth, Stem 4-6 in., occasionally as much as

10 in. high, 1-2-foliate below, closely 2-flowered at the apex. Spathes herbaceous,

keeled, 1}-2in. long. Pedicel very short. Perianth with the tube greenish

or upwards somewhat flushed or blotched with purple, 1-1} in. long, shorter than

or at the most equalling the spathes ; outer segments with a reflexed elliptic or

obovate limb, 1J-1} in. long, 3-1 in. wide, yellowish but suffused with purple

towards the margin and with a yellow crest, or lurid purple throughout and then

with a bright blue crest ; claw narrowly cuneate, }—1 in. long, with rather pale

suddenly or less often gradually contracted into a red-blotched claw, including

the claw 14-2} in. long, 1-1} in. wide, of the same colour as the outer segments,

but rather’: more vivid. Anthers rather shorter than the filaments. Ovary

of the crest obliquely ovate, toothed.

The Delphinium here figured was first met with in

1872 by Przewalski on the Kansu border, on the mountains

just south of the Tetung River. It was first flowered in

the Botanic Garden at Petrograd in 1876 from seed

communicated by Przewalski, and was named _ by

Maximowicz D. Pylzowii, in honour of Przewalski’s

travelling companion, M. A. Pylzow. Przewalski gathered

the species again in 1880 at elevations of 9,000 to 11,000

feet, between Kuku-Nor and the Tetung, and it has since

JULY-SEPTEMBER, 1919.

then been found by Wilson near Sun-tang, in the Si-fan

region of north-western Szechuan, as well as by Farrer

in Kansu. From Farrer’s indication, ‘On the Eaves

of the World,” vol. ii. p. 186, his locality is in the Min-

Shan range, somewhat to the north-east of Wilson’s

collecting ground. Our figure has been prepared from

a plant presented to Kew by Mr. Farrer in June, 1917.

Of two plants then received, one was grown in the Rock

Garden, the other kept in a pot in a cold frame. The

species has proved to be a hardy perennial, both plants

flowering in May, 1918, when our drawing was made.

Both plants produced good seed, and survived the winter

following; both flowered again in May, 1919. The

conditions most suitable for D. Pylzowii are those needed

for the well-known D. grandiflorum, Linn. Although the

dark azure-violet shown in our _ illustration appears +0

be the normal colour of the flower, Maximowicz records

the existence of a form with pale rose or rose-lilac

blossoms. 2

Description.—Herb, perennial with several stems, 4—14 in. high, rising from

a slender crown ; stems slender, erect or ascending, softly pubescent or almost

villous with spreading or somewhat deflexed hairs, more or less branched, the

branches long. _ Leaves pedately lobed, the radical like the lower cauline, but

The section Magnipuncta, recognised by Haworth within

the large and polymorphic genus Mesembryanthemum,

includes only two forms, the original M. magnipunctatum,

Haw., and the one now figured, which Haworth at first

was inclined to regard as only a variety of M. magni-

punctatum, but at a later date treated as a distinct

species, M. nobile. The original VM. magnipunctatum was

based on a plant collected by Burchell and cultivated

at Kew nearly a century ago. There is a coloured drawing

in the Herbarium collection of a flowerless example

which was collected on the heights near the Zekoe River

by Bowie in 1818. When Haworth indicated the exis-

tence of the variety nobile, he tentatively referred to

that variety the plant regarded by Prince Salm-Dyck

as M. magnipunctatum, and this plant became the type

of M. nobile, Haw., in 1823. There is at Kew a coloured

drawing of Haworth’s second species which is noted

as having been received from Prince Salm-Dyck. The

JULY-SEPTEMBER, 1919.

plant shown in that drawing is again without blossom,

but the species was afterwards figured in Salm-Dyck’s

monograph. Salm-Dyck obtained his plant in 1814

from Vienna. Since then J/. nobile has been collected at

the Gamka River, Prince Albert Division, Cape Colony,

by Zeyher, and, according to Berger, it has also been

met with by Marloth in the adjacent Beaufort West

Division. Plants both of I. magnipunctatum and M.

nobile were presented to Kew in 1916 by Mr. Cecil

Hanbury, from the La Mortola collection, and the figure

of the latter now given has been prepared from the

La Mortola example, which agrees well in its essential

characters with those of Bowie and Salm-Dyck. The

differences between the two allied species are well shown

by the examples of each now grown at Kew, where they

thrive well and flower in summer in a green-house.

Description.—Herb, small and stemless. Leaves 4-6, connate at the base,

spreading or slightly recurved, oblong, rather blunt, thick, flattish above, slightly

angled beneath, 1}-2} in. long, }-% in. wide, glaucescent, closely dotted with

green spots. Flowers almost sessile, showy, 2-21 in. across. Peduncles nearly

obsolete, thick, with two fleshy bracts resembling the leaves. Calyx nearly

globose, about 3 in. long, 5-6-lobed; lobes lanceolate-oblong, rather blunt,

fleshy. Petals several-seriate, linear, golden-yellow, 1-1} in. long. Stamens

many ; anthers oblong. Ovary nearly globose, conical upwards, finely verrucose ;

styles about 16, erect, subulate, slightly plumose on the face.

The material for the accompanying figure of Rhodo-

dendron dichroanthum we owe to the courtesy of Mr. J. C.

Williams, in whose collection at Caerhays it flowered

in May, 1918. ‘The species is one discovered by Mr. G.

Forrest in July, 1906, at altitudes of from 9,000 to

11,000 feet above the sea, in shady situations of the

open country on the eastern flank of the Tali Range, in

western Yunnan, in 25° 40'N. Lat. Of two distinct

gatherings of the species obtained in 1906 Forrest

describes the corollas as being creamy rose or yellowish

rose. The plant now figured had, however, purplish-red

flowers, and Mr. Millais records the corolla of this species

JuLY-SEPTEMBER, 1919.

as being very variable in colour. Mr. Williams says with

regard to this Rhododendron that perhaps sufficient is not

yet known as to the most suitable situation, but in cases

where a choice is possible it would be preferable, judging

from its behaviour under conditions to which it has

already been subjected, to select a cool damp slope with

no overhead shade, with an eastern aspect or one even

to the north of east, but with at the same time shelter

from wind. R&. dichroanthum is closely allied to R. nerii-

florum, Franch., figured at t. 8727 of this work, but is

readily distinguished by the mealy hairy covering on

the under surface of the leaves and by the puberulous

filaments. Both species are remarkable for the presence

of large outgrowths within the base of the corolla-tube.

Description.—Shrub, evergreen; year-old twigs glabrescent, about 4 in.

thick, with pale brown bark ; young shoots closely covered with a webbed white

tomentum. Leaves when mature oblong-lanceolate, narrowed at the base,

in Yunnan, 27° 55’ N. Lat., at about 12,000 to 13,000

feet above sea-level, where it grows in open Alpine

meadows. Seeds of P. chionantha were presented to

Kew by Mr. J. C. Williams, of Caerhays Castle, Cornwall,

in April, 1915, from the fruits of Mr. Forrest’s collection

of 1914 on the Mekong-Salwin divide, also in Yunnan. -

i were raised and planted in the Rock Garden

at Kew, where they flowered in May, 1917, when our

figure was prepared. The species has proved perfectly

hardy at Kew, but, like all those belonging to the same

JuLy-SEPTEMBER, 1919.

group, died after flowering. Abundant good seed was,

however, produced, and from this a further stock of

plants has been raised. P. chionantha thrives best in

a shady situation in moist rich soil. The species is

compared by Professor Balfour with the Oriental and

North Asian P. nivalis, Pallas. It differs from P. nivalis

mainly in its nearly entire leaves, its constantly verti-

cillate inflorescence, and its shorter calyx. It is also

taller and more robust in habit.

Description.—Herb, stout and mealy, 14-28in. high. Leaves obovate-

oblanceolate or oblong-elliptic, blunt, narrowed at the base into a veined winged

This Brachystelma was first discovered near the Mooi

River, Transvaal, by Joseph Burke, some time between

1840 and 1842. It has since been collected in several

other localities in the Transvaal, also in the Orange River

Colony, Basutoland and Zululand. Tubers of the plant,

collected near Pretoria, were sent to Kew in January,

1917, by Mr. A. M. Bottomley of the Division of Botany,

Pretoria, and from one of these the material for the figure

was obtained in the following May. It is an interesting

and curious plant, but scarcely ornamental, and its

flowers, as is often the case in the family, have a very

disagreeable odour. The tubers are eaten by the natives,

JuLyY-SEPTEMBER, 1919,

and are known as Hottentot’s bread : in the raw state they

have a bitter taste. Several species of Brachystelma are,

or have been, in cultivation; these include B. tuberosum,

R. Br. (t. 2343), B. craspum, Grah. (t. 3016), .B. Barberiae,

Harv. (t. 5607), and B. ovanthum, Schlechter (t. 8670),

which have been figured in this Magazine. The genus

comprises about seventy-four species, of which forty-five

are natives of South Africa, and nineteen of Tropical

Africa ; there are several in India, one in Siam, and one-

in New Guinea. At Kew B. foctidum is cultivated in a

dry tropical house devoted to succulent plants, where it

flowered for the first time in August, 1918, when the

figure now given was prepared.

Crataegus Wattiana belongs to Zabel’s section San-

guineae, a group of Central and North Asiatic thorns

characterised by dark shining purplish-brown young

shoots, and a calyx whose lobes are entire and shorter

than the tube. It is closely allied to C. sanguinea, Pall.,

with the yellow-fruited form of which it has been con-

fused. The material for our figure was gathered from a

tree purchased in 1900 from a continental nursery under

the name “ C. sanguinea, var. xanthocarpa.”” The forms

of C. sanguinea are, however, to be distinguished by the

invariably cuneate base of the leaf, the more or less

pubescent foliage, and the pilose summit of the ovary.

In C. Wattiana the leaves, especially on the barren

JuLY-SEPTEMBER, 1919. :

twigs, are often truncate or even slightly cordate, the

foliage is perfectly glabrous, as is also the summit of

the ovary. The type specimen of C. Wattiana in the

Kew Herbarium was collected by Mr. J. H. Lace in 1888

in the Urak Gorge, Baluchistan, at 7,200 feet, and it

was named three years later by Messrs. Hemsley and

Lace in their paper on the vegetation of that country,

published in the Journal of the Linnean Society. The

name “altaica” first appeared in 1838 in Loudon’s

“ Arboretum et Fruticetum Britannicum” (vol. ii.

p- 823), where it is quoted as ‘‘C. altaica, Ledebour in

Loddiges’ Catalogue,’ and reduced to C. purpurea,

var. altaica. In 1897 the name was taken up by Lange

in the work cited above, but it is doubtful whether his

plant and the one now figured be identical with that

mentioned by Loudon as growing in the nursery of Messrs.

Loddiges at Hackney in 1837. Even assuming its validity,

Lange’s name is superseded by Hemsley and Lace’s older

one. The greatest beauty of C. Wattiana is in August, when

its fruits become ripe and acquire that clear and remarkably

translucent vellow colour which makes them so distinct

from the fruits of any other Crataegus we cultivate.

The flesh is soft, and when once fully ripe the haws soon

begin to fall from the branches. The tree at Kew is fifteen

feet in height. !

Descrrption.—Tree, probably not exceeding 20 ft. in height when full-grown,

unarmed, with a lax spreading head of branches ; bark of trunk peeling ; young

he dark brownish-purple, shining, glabrous ; winter-buds blunt and rounded,

ark shining brown. Leaves deciduous, broadly ovate on the fertile shoots,

The genus Baikiaea was named in honour of the late

Dr. William Balfour Baikie, of the Naval Medical Service,

who was surgeon to the Niger Expedition of 1854 and

did much to further our acquaintance with the vegetation

of West Africa. The species now figured was first col-

lected by the late Mr. G. Mann in the island or fernando

Pe in 1863, and described by Mr. Bentham as B. insignis

in 1865; it has since then been met with on the African

continent in Lagos, the Cameroons, and the French

Gaboon. There is a closely allied species, B. minor,

OcToBER-DECEMBER, 1919.

Oliv., which occurs in the Cameroons, the Congo State

and Uganda, with smaller flowers and obtuse emarginate

leaves. Other species, with much more numerous and

quite small leaflets and flowers, are to be found in Angola

and in the Zambesi basin. The flowers of B. insignis

are probably the largest known in the suborder Caes-

alpinieae of the family Leguminosae. The dorsal petal is

distinctly coloured and exhibits the additional peculiarity

of embracing the tenth, and quite free, stamen which it

thus keeps apart from the remaining connate stamens,

perhaps at a suitable time opening a door whereby birds

or insects may obtain access to the nectaries. The

plant whence the material for our figure has been

obtained was received at Kew in 1894 from the Botanical

Station, Lagos. It flowed for the first time in a tropical

house in July, 1914. Planted in a border in this house

it has grown to a height of thirty feet, and in J uly, 1918,

it flowered more profusely than in previous years. The

flowers are extremely fugacious and in size, texture and

colour recall those of Camvensia maxima, figured at

t. 7572 of this work, save that the yellow colour in the

latter case, instead of being confined to the dorsal petal,

Occurs as a marginal line on every petal.

Description.— Tree, 85-45 ft. high; twigs flexuous, almost glabrous, closely

lenticelled. Leaflets 8 or 4 or 5, alternate or nearly opposite, obliquely oblong-

elliptic, gradually acuminate and somewhat blunt at the tip, base rounded

and umbonately thickened on one side, 5-12 in. long, 13-8} in. wide, entire,

coriaceous, closely reticulate on both surfaces, rather shining beneath ; midrib

flat above, raised beneath ; lateral nerves many, indistinct ; petiolules thickened,

about 4 in. long, wrinkled transversely ; stipules small, ovate-lanceolate,

scale-like. Flowers very large, few, nodding, clustered at the tips of the twigs,

densely velvety in bud; bracts and bracteoles wide-ovate, concave, }-} in.

The Polygonaceous shrub here figured was first met

with in the Lebanon by La Billarditre about the year

1787, but was not described until 1844 when Jaubert

and Spach named it Atraphaxis Billardiert in honour of

its discoverer. The area of the species extends from

eastern Greece to Asia Minor and Syria. It appears to

be restricted to rather high elevations; in Greece it does

not occur under 2000 feet above sea-level ; in Crete it is

only met with above 4500 feet; in Asia Minor and the

Antilibanon it begins at 4000-5000 feet. The Greek

specimens of this Atrapltaris, collected by Zuccarini in

Aetolia and Euboea, were described by Meisner as vari-

etally distinct, but this author’s var. graeca, apart from

OcropeR-DECEMBER, 1919.

its occurrence at lower elevations, is distinguished mainly

by the more attenuated, lanceolate and acute leaves, and

subsequent authors have not recognised Meisner’s variety.

Another form, which has tetramerous flowers among the

typically pentamerous ones, was described and figured

by Jaubert and Spach (Ill Pl. Or. vol. ii. p- 13, t. 110)

as A. variabilis, and regarded by them as a distinct

section (Zragatraphaxis) of the Linnean genus. Boissier,

however, regarded this fcrm as only a variety (var.

heterantha) of A. Billardiri, and it differs in no other

character from the form represented in our plate, which

has been prepared from a plant in the collection at Kew,

obtained by purchase from Mr. F. Sundermann of

Lindau in 1903. The only other representative of the

genus Atraphaxis which occurs in Europe is the Crimean

A. spinosa, Linn. In Asia, however, the genus ranges

rather widely from Sinai, Syria, Asia Minor and the

Caucasus over the whole of Iran and Central Asia to

Lake Baikal. It is a distinctly xerophytic type and

includes about a score of species, similar in habit, which,

notwithstanding their inconspicuous flowers, produce a

pleasing effect inthe more or less arid regions they occupy

owing to the charming coloration of the persistent and

accrescent perianth-segments. This characteristic is well

manifested in A. Billardieri which, as grown on a slope

in the Rock Garden at Kew, forms a dwarf semi-prostrate

shrub, that thrives well and flowers freely every year in

midsummer.

Derscriprion.— Shrub, 13-23 ft. high, more or less prostrate, the sterile twigs

often ultimately developing into spines ; young shoots finely puberulous; the

bark at length greyish-brown or grey. Leaves green, glabrous, short-petioled

and jointed at the junction with the stalk; blade rather variable in outline,

The pleasing Primula now figured was first collected

by the late Abbé Delavay in June, 1884, cn Mount

Tseng-chan, near Tali, in Western Yunnan, at about

7000 feet elevation. A year later it was described as

P. spicata by the late Mr. Franchet. A member of the

section Soldanelloides, this species is distinguished within

that group by its loosely spicate flowers; in other

species of the section the flowers are usually capitate.

Except in this particular P. spicata most resembles

P. chasmophila, Balf. f., figured at t. 8791 of this work.

During September and October, 1906, P. spicata was

OcToBER-DECEMBER, 1919.

collected again at the rather higher altitude of 11,000

feet, by Mr. G. Forrest, on dry rocky slopes and ledges

of cliffs in side valleys on the eastern flank of the Tali

range. In August of the same year Forrest had

gathered a smaller plant in the same neighbourhood.

This the collector described as P. delicata, but it is now

known that P. delicata, Forrest, is only a diminutive

form of P. spicata. A decade later, seeds of P. spicata

were collected on the Tali range by Mr. Forrest, and

from these plants were raised by Messrs. Wallace, of

Colchester. Our figure has been prepared from one of

these plants which was presented to the Kew collection

by Messrs. Wallace. There is no difficulty in rearing

and growing this Primula from seed. Like so many

other species from China and the Himalaya, P. spicata

proves strictly biennial, and dies after flowering. Un-

fortunately at Kew it failed to produce seeds.

Description.—Herb, monocarpic, up to 6 in. in height. Leaves all radical,

petioled, oblong- or obovate-elliptic, gradually narrowed at the base into a

petiole up to 1 in. long, blade 3-14 in. long, 4-3 in. wide, doubly serrate-crenate,

thinly papery, shortly crisped-pubescent on both surfaces; midrib somewhat

prominent beneath, with spreading hairs, lateral nerves about 5 along each

The Crassulaceous plant here figured appears to be

rather rare in collections as well as in nature. It was

originally collected in woods on the Abkhasia Range in

the Caucasus, at the base of Mount Hirtscha, by Nord-

mann some eighty years ago, and Boissier has recorded

its collection subsequently in the Caucasus by Owerin

and by Radde. There is in the heibarium at Kew a

specimen gathered by Nordmann and communicated by

Ledebour, while there is another obtained in 1893 by

Alboff, on alpine rocks on Mount Migaria. It is not

certain how long it has been in cultivation in England

or by whom it was first introduced ; the material for our

plate was supplied by Miss Willmott, in whose garden

at Warley Place it flowered in June, 1916. A graceful

plant, with opposite decussate, somewhat crenate flattish

leaves and small yellow flowers borne on branched spikes

so as to form an open panicle, the species is somewhat

OcroBpeR-DECEMBER, 1919.

remarkable in its natural family and its position is there-

fore rather open to dispute. When first described by

Ledebour in 1837 its author placed it in the genus

Cotyledon, as understcod by Linnaeus, and named it

C. oppositifolia. A few years later Ledebour, however,

transferred it to the genus Umbilicus, as characterised

by De Candolle in 1801, though to accommodate this

‘Caucasus plant he defined a monotypic section Chias-

tophyllum. Boissier, in 1872, followed Ledebour’s later

treatment; Bentham and Hooker in 1865, however,

found it preferable to merge Umbilicus as a whole in the

genus Cotyledon. This treatment, which is followed here,

renders it necessary to employ the earlier name, Cotyledon

oppositifolia, proposed by Ledebour.

Description.—Herb, perennial, glabrous, prostrate and rooting below, with

above glabrous erect stems 6-10 in. high. Leaves opposite, decussate, more

or less fleshy, shortly petioled, elliptic or ovate-elliptic, obtuse, crenate, 1-13 in.

long, 3-14 in. wide, nearly flat or slightly concave, glabrous; petiole about

2 in long. Racemes branched, spicate, many-flowered, arranged in a loose

panicle; bracts linear, acute, 51; in. long. Flowers small, yellow, shortly

pedicelled. Calya 5-partite ; segments ovate-oblong, somewhat obtuse. Corolla

ellipsoid, 2-4 in. long, 5-fid; lobes erect, apiculate. Stamens 10; filaments

inserted below the corolla throat. Carpels 5,4 in. long; nectariferous scales

Euonymus alatus is found wild over a great area, and

occurs in Japan, Manchuria, Amurland, North and

Central China. We have not been able to trace its first

introduction to this country, but it was cultivated in

Berlin nearly sixty years ago. According to our

experience at Kew it does not develop its handsome

fruits very frequently in our climate, and we are

indebted to Messrs. Waterer and Crisp of Bagshot for

the specimens now figured. The species has, however,

long been valued in gardens for its great autumnal

OcroBER-DeEcEmBeER, 1919,

beauty, its leaves at that season turning to soft, rich

shades of red. It may be described as one of the

best hardy shrubs for autumnal colour, and when, as in

1917, to this is added the colour effect of its purple and

scarlet capsules it becomes very attractive indeed.

From all other cultivated Spindle-trees Z. alatus is very

distinct by reason of the conspicuous corky wings of the

branches. From its nearest ally, /. verrucosus, it is well

distinguished by this character, also by its shorter cymes

and more deeply lobed capsules. £. alatus is very

hardy, even in Central Europe, and likes a_ position

exposed to full sunlight. It thrives in either a loamy or

a peaty soil and, failing seeds, can be propagated by

cuttings.

Description.— Shrub of stiff, open habit, 6-10 ft. high, usually wider ‘than

8. A SKan,

The genus Thorncroftia, of which the species now

figured is the only one at present, is a native of the

Transvaal, where it was collected at Barberton by Mr.

J. N. Thorncroft, growing among rocks at an elevation

of 4000 feet, in 1911. When describing the genus Mr.

N. E. Brown expressed the opinion that 7. longiflora in

general appearance resembles Syncolostemon densiflorus,

Benth., so closely that when not in flower the two might

possibly be mistaken. When in blossom, however, the

two are very easily distinguished since in Thorncroftia

OcropeR-DEcEMBER, 1919.

the limb of the corolla is 4-lobed whereas in Syncolosteman

the limb is composed of two entire or only slightly

lobed lips. The 3-partite lower lip of the corolla and

the deeply 2-fid style separate Thorncroftia from Ortho-

siphon. For the introduction of 7. longiflora to European

collections, horticulture is indebted to the collector in

whose honour it has been named. From seeds sent by

him to Mr. R. Irwin Lynch, Curator of the Cambridge

Botanic Garden, plants were successfully raised and have

thriven best under the treatment as regards potting,

soil and watering usual for succulent plants, though

they succeed satisfactorily in any greenhouse or inter-

mediate house with good light. Under cultivation

I. longiflora forms a small shrub of loose habit with

succulent leaves and is not particularly attractive save

when in flower, when it is somewhat remarkable for the

Jong slender tube of the corojla. For the material for

our plate we are indebted to Mr. Lynch who supplied

it from one of the plants which flowered at Cambridge

in November, 1916. :

Descrirtion.— Herb, perennial, densely puberulous throughout. Stems

erect, up to 2 ft. high, branched, when young more or less red, ultimately

rather woody. Leaves short-petioled, elliptic-lanceolate, obtuse, entire or

obscurely sparingly toothed, cuneately narrowed into the petiole below, rather

thick, including the petiole 3-3 in. long, up to 3 in. wide, densely beset with

sunk glands. Verticillasters 2-flowered, forming racemes 1}~4 in. long which

are grouped in a terminal panicle over 5 in long; nodes between the

verticillasters {-} in. long. Bracts like the leaves, progressively smaller

upwards, the highest very small, sessile. Pedicels 1-1 in. long. Calyx

—R. A. Roure.

The interesting Orchidaceous genus Sigmatostalix in-

cludes about a dozen species, the majority of which are

characteristic of the Andes from Peru northwards to New

Granada. It is one of the rather numerous small genera

recognised within the sub-tribe Oncidieae of the tribe

Vandeae, and is especially distinguished by the ungui-

culate suberect lip, which is usually truncate or sagittate

at the base, as well as by the elongated column. The

genus, which now for the first time finds a place in this

work, extends beyond the Andes, for S. costaricensis, the

species now figured, was discovered in Costa Rica by

Mr. C. H. Lankester, who sent a living plant to Kew

which flowered in the collection in October, 1915, and

remained in bloom for a considerable time; our drawing

was made in December of that year. Though the

interest attaching to this species is mainly botanical, it

is nevertheless a very graceful little plant, in general

appearance not unlike a small Oncidium, with the flowers

borne on an elongated spike. The sepals and petals are

OcToBER—DECEMBER, 1919,

narrow and considerably reflexed, and are pale green

with a brown central stain ; the sagittately cordate lip is

deep red-brown with a yellow apex. It thrives satis-

factorily in a house devoted to species of Oncidium and

other orchids requiring intermediate conditions.

Description.—Herb with -close-set ovate-oblong compressed and angled

pseudobulbs, {-1 in. long, 1-foliate at the apex and 2-3-foliate at the base.

Leaves oblong-lanceolate, somewhat acute, 2-5 in. long, 4-3 in. wide. Scapes

The striking Rose here figured has been in cultivation

in the Kew collection as Rosa glutinosa since 1896, in

which year the plant from which the material for our

plate has been derived was received from Darmstadt

under this name. This plant is conspicuous in the

collection by its dwarf habit and its gooseberry-like fruits

which ultimately assume an orange-red colour. In Miss

Wilmott’s magnificent monograph of the genus Sosa

this is figured under the Darmstadt name. It has long

been suspected, however, that there was some confusion

and that this is not the original /?. glutinosa of Sibthorp

and Smith. An exhaustive comparison of the material

preserved at. Kew and in the Natural History Museum

and the examination of the original Sibthorpian type at

Oxford enabled Mr. Rolfe in 1918 to state definitely that

OcroBER-DECEMBER, 1919.

the Darmstadt 7. glutinosa is the plant described and

figured by Kerner in 1870 as PF. dalmatica. Kerner’s

plant was collected, probably in 1869, by Mr. F. Maly on

Mount Bila-Gora, near Cattaro in Southern Dalmatia.

Living plants were transmitted to Vienna and distributed

thence, so that it is not impossible that the Kew plant is

one derived from this source. Borbas has regarded this

Dalmatian Rose as a variety of L. glutinosa, but has

recognised the marked difference in the shape of the fruit

as seen in cultivation. In £&. glutinosa proper the fruits

are globose, not ovoid. In adopting the arrangement

proposed by Borbas we would point out that the precise

relationship of the Dalmatian plant to &. glutinosa is not

yet clear. It certainly belongs to the group of Roses

from South-eastern Europe and Asia Minor with a close

affinity to the fubiginosae or Sweet Briars. To the group

in question Crepin assigned the name Orientales, and

treated it as a section which includes R. glutinosa and

various other forms, some of which are still imperfectly

known. The dwarf compact habit of R. glutinosa var.

dalmatica makes it suitable for the Rock Garden or for

positions where it is not likely to be overgrown by

shrubs of coarser habit. Its flowers are pleasing and the

conspicuous covering of glandular hairs makes it interest-

ing, but its greatest beauty is seen in autumn when its

bright and bristly fruits are ripe. For so dwarf a rose

they are noticeably large. The plant must have a sunny

position and prefers a rather heavy loamy soil,

Descriprion.—Shrub, erect, but dwarf, hardly more than 1} ft. high;

The Campanula here figured inhabits dry, sandy places

also been recorded from the Isthmic Desert and the

northern parts of the Arabian Desert within Egyptian

territory. Its nearest allies in the genus are C. strigosa,

Russ., figured at t. 5068 of this work, C. Reuteriana,

Boiss. et Bal., and C. hierosolymitana, Boiss., all oriental

species, in which the corollas are blue or violet. In

C. sulphurea the corolla is of an intense yellow colour, a

character which at once marks it off from the three.

nearly related species mentioned. The plant figured in

our plate was raised at Kew from seed presented by

Major P. M. Armitage, Great Budworth, Northwich, who

had received a supply from Palestine in 1917. The

plants in cultivation at Kew, though they flowered freely

OcTroBER-DECEMBER, 1919.

in October, 1917, did not ripen seed. In 1918 some seed,

saved from the gift of the previous year, was sown in

March, and the resulting plants, grown in pans in a frame,

flowered freely in July. The species unfortunately can-

not be said to be hardy at Kew, and although it can be

raised satisfactorily in pots, provided freshly imported

seeds are available, its liability to attack by slugs makes _

- a to preserve in a rock garden or elsewhere out

of doors.

nearly simple, more or less strigose-hirsute. Leaves of the stem sessile, oblong-

linear, obtuse, rounded at the base, up to 2 in. long and } in. broad, strigose-.

recent monograph which we owe to Mr. A. Berger, in-

cludes some three score species, and it is somewhat

remarkable that in the case of five-sixths of the species

_ enumerated in the ‘ Flora Capensis’ the precise habitat

was unknown in 1896. Most of these species were intro-

duced to cultivation in Europe towards the close of the

18th and the beginning of the 19th Centuries, during a

period when the growing of succulent plants was much

in vogue. Many of these were first described by the

late Mr. A. H. Haworth, one of the founders of the Hull

Botanic Garden, in whose honour Mr. H. A. Duval

named the genus to which the plant here figured belongs.

A few of the members of this genus had been described

by earlier authors as species of Aloe, from which, how-

ever, J/aworthia, as understood by Duval, differs in

having a perianth with an oblong tube and a bilabiate

OcToBER-DeEcEMBER, 1919, ;

limb. The only species of Haworthia recorded from out-

side South Africa is the Angolan H. angolensis, Baker, but

it now appears that this exception is only apparent, for

fH. angolensis has been transferred by Berger to his

genus Chortolirion as C. angolense. The genus Chortolirion.

Berger, was founded for the reception of those species

referred by Baker and Engler to Haworthia which differ

from the true Haworthias in having their leaves narrow

and comparatively thin above, but wide and conniving

in a balb-like fashion below. The subject of our plate,

H. Chalwini, is a very striking species of columnar habit;

it bears most resemblance to //. Reinwardtii, Haw., with

which it agrees in the bronze-purple colour of the leaves

and in the pearly protuberances on their under and

outer surface. The material for our figure has been

derived from a plant raised from a cutting presented

by Dr. Marloth in 1913. This plant flowered in a

succulent house at Kew for the first time in

October, 1916.

The Chinese Gaultheria now figured was originally

described by Messrs. Rehder and Wilson as a variety,

var. cuneata, of G. pyroloides. The name G. pyroloides

was originally given in 1864 by Miquel to a Japanese

plant which he had identified (Ann. Mus. Bot. Lugd.-

Bat. vol. i. p. 30) with one collected by Sir Joseph

Hooker in Sikkim in 1849. The name he used was

attributed by Miquel to Hooker and Thomson. But

these authors never published such a name, although we

know that Hooker at one time intended to call the

- OcroneR~DEcEMBER, ‘1919.

Sikkim plant ‘“ pyrolaefolia,” that word being inscribed,

in his own handwriting, on the original sheet in the

herbarium at Kew. When drafting the account of the

Ericaceae for the ‘Flora of British India’ in 1882,

Mr. C. B. Clarke made use of this indication and

described the Sikkim Gaultheria as G. pyrolaefolia, Hook. f.

No reference is made by Clarke to the misreading of

Hooker’s name by Miquel or to its employment by the

latter to designate a plant from Japan. Nor was there

any obligation to do so, since a critical examination of

the available material of both plants proves that the

Japanese and the Sikkim plants are very distinct species.

It is found too that the Chinese plant now figured is

equally distinct from the two with which it has been

nominally confused. In the Sikkim plant, G. pyrolae-

folia, Hook. f. ex C. B. Clarke, the leaves are few in

number and are situated near the end of the twigs,

rounded-obovate or nearly orbicular ; the anther append-

ages are shorter than the anther-cells; the style is much

shorter than the corolla-tube and the ovary is glabrous.

In the Japanese plant, G. pyroloides, Hook. f. and Thoms.

ex Miq., the leaves are numerous, more or less elliptic ;

the anther-appendages are longer than the anther-cells ;

the style reaches the top of the corolla; the ovary and

fruit are glabrous as in the Sikkim species. Our Chinese

plant, G. cuneata, Bean, differs from the other two both

in its narrowly obovate to oblanceolate leaves and in its

densely hairy ovary and fruit. It is a neat dwarf ever-

green, perfectly hardy so far as our present experience

goes. The plant from which our figure was prepared

was raised at Kew from seed sent to Kew from the

Arnold Arboretum in 1909. The seed had been collected

the previous autumn in Western Szechuan by Mr. E. H.

Wilson, who states that the plant grows in woodlands,

nearly always on rocks. It thrives under the same

conditions as the other Gaultherias, which love a moist

peaty soil. Propagation is easily assured by its plentiful

seeds. The Gaultherias are interesting on account of

their curious fruits. Commonly spoken of as berries,

and to all appearance such, they are in reality 5-lobed

capsules almost completely enveloped when ripe by the

calyx which with age enlarges, becomes fleshy, and is

often coloured. In G. cuneata, however, it happens to

be white.

DescripTion.—Shrub, evergreen, 1-14 ft. high, of close compact habit;

young shoots very leafy, densely pubescent. Leaves alternate, persistent,

coriaceous, obovate or narrowly oval, acute, cuneate at the base, shallowly

crenulate, each tooth tipped with a dark gland; 3-1} in. long, }-} in. wide;

dark shining green and glabrous above, paler shining green and sparingly

dotted with glands beneath; nerves sunk above, prominent beneath; petiole

zs in. long. Racemes puberulous, 1-1} in. long, terminal and axillary;

pedicels puberulous, furnished with two scarious bractlets. lowers white,

cernuous, opening from midsummer onwards. Calyx whitish, 5-lobed,

the lobes triangular-ovate, ;4; in. long, minutely ciliate. Corolla white,

urceolate, + in. long, with five very small recurved lobes. Stamens 10,

enclosed ; filaments puberulous, swollen towards the base; anthers 2-lobed,

each lobe terminated by two slender horns; pollen white. Ovary pentagonous,

silky-puberulous; style glabrous, columnar, as long as the corolla. Fruit a

5-lobed, many-seeded,=pubescent capsule, enclosed except at the top by the

calyx become white and fleshy, the whole resembling a globose, white berry,

% in, wide. Seeds minute, shining, brown.
