The African genus Encephalartos includes twenty-four

species. The precise habitat of four of these is obscure ; of the

remainder fourteen are South African and six are natives of

“Tropical Africa. Four of the known South African species

have already been figured in this work: E. Altensteinii

(B. M. t. 7162); 2. Caffer (B. M. t. 4903); a form of

LE. horridus (B. M. t. 5371); and E. villosus (B. M. t. 6654).

£. Barteri, the Tropical African plant now dealt with, in

habit and appearance most resembles the South African

species last named, but is readily distinguished by the

diagnostic characters given*above.

E.. Bartert, known in West Africa as the Pardi Attar or

“Ghost Palm,” was originally met with during Dr, Baikie’s

January, 1909,

Niger Expedition of 1858, when it was collected by the late —

Mr. C. Barter “three miles south of Jebu on the Yoruba |

side.” The discovery afforded the first evidence of the.

existence of the genus in Tropical Africa. The name —

proposed for the species by Mr. Carruthers was taken

up by Professor Miquel and is not invalidated by the fact

that in his original account Miquel associated with Barter’s

specimens the leaves of another species from Natal. \ The

species was again met with on the Upper Volta in 1865 by

the Rev. ©. Schénfeld of the Gold Coast Basel Mission.

Schinfeld took advantage of the re-opening of this territory

after Sir John Glover’s campaign to revisit the Upper Volta

and bring back with him an old full-grown tree and a>~™

further supply of botanical specimens which he sent to Kew

in 1875, Further material was communicated in 1882 by

Commander R. M. Rumsey, R.N., and in 1890 Sir A.

Moloney sent asupply of living plants which he had secured,

from Anum on the Upper Volta, through the co-operation of

the Basel Mission. In 1898 more material was sent from

the Gold Coast by Mr. W. H. Johnson; there is also at

Kew a leaf obtained in Dahomey, 300 miles from the Cc

by the younger Mr. Poisson. arly in 1908 Mr. J. |

Anderson sent to Kew a number of living plants and fresh

female cones from Labo Labo on the Voita. One of these

cones is now figured; the male cone depicted was collected

by Barter; the embryo and suspensors have been drawn ~

from a preparation by Mr. Hemsley. —

Barter only met with the plant in one locality “in a dry

rocky valley ” and Schénfeld, in a letter to Sir J. D. Hooker,

speaks of it as only occurring on rocky hills “shooting out —

of the crevices of the rocks.” The stem is described by

Barter as hardly rising above the surface of the soil, the

largest seen by him being 1 ft. in height and 9 in. across.

The striking name of “Ghost Palm,” independently —

recorded for the plant by Schinfeld, Rumsey and Moloney, —

is explained by Schinfeld as being used to express the —

absence of all virtues from this plant as compared with the —

valued Oil Palm, Elaeis guineensis. Moloney, however, —

(Forestry of West Africa, p. 215,) records, as illustrative of

the difficulty in obtaining reliable information in matters

of this kind, an alternative explanation which attributes

malignant qualities to this handsome species, oe

Cuntivation.—A barrel containing a number of stems of

Ky. Barteri was received at Kew in 1890 from the Botanic

Station, Lagos. Some of these stems were distributed to

various botanic gardens, others were planted at Kew. The

plants, however, did not long survive; nor have stems

subsequently received lived for more than about three years.

While, however, this has been the case as regards this

cycad, FE. villosus, the species to which 2. Barteri appears

most closely allied, is perfectly happy under cultivation it

cones regularly in the Palm House at Kew and is one of the

most handsome of cycads. In both species the stem is conical |

and it may be that in a wild state both are deciduous. At

Kew E. Barteri rarely has more than three leaves, and

although carefully grown in a moist tropical house, only one

of the stems has produced a cone. ‘The largest stems

received at Kew have not exceeded a foot in height.

Descriprion.—Stem short, rarely exceeding 1 ft. in

height and 9 in. across, closely covered with persistent

imbricated leaf-bases clothed with grey cottony tomentum.

Leaves erect or suberect, 34-54 ft. long, 9-10 in. wide

towards the apex, bright green; petiole and rachis sub-

cylindric, clothed at first with a deciduous grey tomentum ;

leaflets usually about 80 pairs, opposite or some near the

apex only subopposite, rather close-set, linear-lanceolate,

+? in. wide, somewhat narrowed at the base, apex pungent,

margin with few ascending small teeth; lower leaflets

diminishing downwards and passing ultimately into weak

spines. Male cone peduncled, pale, narrow-cylindric, 5—9 in.

long, 2 in. wide; scales spreading, deltoid, very shortly

stipitate, subpeltate, triangular, 2 in. wide, inferior margin

entire. Female cone subsessile, dark olive, oblong-eilipsoid,

8 in. long, 5 in. wide; scales long-stalked, apex obliquely

- deflexed, peltate, wide-rhomboid with the lateral angles

explanate, 21 in. across, inferior margin entire. Seeds

ovoid-oblong, faintly angled, at length protruded between

the scales of the mature cone, 1} in. long; testa crimson.

Dr. Stapf finds that the South American Hchitideae, more

particularly those referred at one time or another to Eehites

and the more nearly allied genera, are in a state of such

confusion as to stand in urgent need of revision. The most’

recent attempt to elucidate the affinities of the species in

this group was that of Miers, whose memoir, “A pocynaceae of

South America,” based on somewhat scanty material, is not

altogether satisfactory. Dr. Stapf points out that Odonta-

denia, to which Mueller has referred the plant here figured,

is characterised by the very short, almost subglobose infra-

staminal portion of the corolla-tube, the densely tomentose

anthers and the very firm wooly follicles explanate when

they dehisce and then over 23 in. across. Within his

Angadenia, Miers has aggregated 26 species which are far

from uniform in appearance. Dr. Stapf therefore proposes

to treat Angadenia in a narrower sense, limiting the name

to a smaller group of obviously allied forms more or less

resembling <A. nitida in facies. This restricted Angadenia

includes Miers’ species A. /ypoglauca, A. coriacea, A. elegans

and A. geminata and appears to be confined to Nor

Eastern Brazil, Guiana and Trinidad.

Cunrivation.—A. nitida, which extends from Para

through Guiana to Trinidad, was received at Kew in 19¢

Eria rhynchostyloides is a recent addition to the genus

which belongs to the section Urostachya, Lindl., and is allied

to EB. floribunda, Lindl., and E. leucostachya, Lind|., but is

remarkable in the section for its short stout pseudobulbs,

A photograph of this species was first sent to Kew from

Paris in 1894 by Mr. Godefroy-Leboeuf who stated that it

had been obtained from Java. It could not be identified,

but in the absence of specimens it was not described. There

are several species from Java which are imperfectly known,

but none of them appear to Mr. Rolfe to resemble the one

now described.

Cuttivation.—The plant now figured, which is that on

which the original description was based, was presented to

Kew early in 1908 by the Hon. Walter Rothschild, Tring.

January, 1909.

It flowered in August, producing three spikes like the one

shown in plate 8234, and was, for an Fria, decidedly

attractive. As cultivated in a tropical house, where it is

planted in a pot filled with peat fibre and sphagnum, it has

grown vigorously. Its behaviour at Kew suggests that it

is likely to prove an easily managed and freely flowering

species.

The species of Clerodendron referable to the section

Cyclonema are characterised by having the lowest corolla-

lobe considerably larger than the other lobes. The section

includes ten or twelve distinct forms, all of which are

African, Of these only one has hitherto been figured in

this work (B. M. t. 5838) as Cyclonema myricoides, Hochst.

(Clerodendron myricoides, R. Br.), itself, as at present under-

_ Stood, a somewhat variable species. From C. myricoides as

there delineated the form now figured differs in having

much shorter semi-orbicular calyx-lobes, a shorter corolla-

tube and larger more deeply coloured corolla-lobes,

Cutrivatton.—Seeds of C. ugandense were forwarded

to Kew in 1906 by Mr. M. T. Dawe, who had collected

them in Voi, Uganda, at 2,000 ft. above sea-level, The

plants have grown freely in an intermediate house, quickly

forming shrubs from 2-3 ft. in height, with long slender

leafy branches terminated by loose racemes of beautiful

blue flowers. Cuttings formed of the young shoots root

readily, and some plants raised in this manner flowered

August. Its behaviour under cultivation and the elegance —

winter-flowering decorative greenhouse shrub. .

For the introduction of this striking Honeysuckle horti-

culture is indebted to Mr. M. L. de Vilmorin, by whom

seeds were first obtained from Szechuen in 1899 and with

whom it first produced flowers in 1903. The plants which

yielded the specimens from which the present figure was

prepared flowered in 1908 in the establishment of Messrs.

Vilmorin-Andrieux at Verriéres-le-Buisson, whence material

was sent to Kew in June, and again in October last.

Although very nearly allied to Z. acuminata, Wall., a

Himalayan species, this Chinese plant, Mr. Hutchinson

points out, is readily distinguished by the somewhat narrower |

leaves which are clothed on both surfaces with a dense,

yellowish, somewhat stiff indumentum.

In his careful synopsis of the genus Lonicera, Rehder has

proposed a new subsection of the section Nintooa for the

accommodation of Z. Giraldii and ten other species that are

distributed from Central Asia and the Himalaya south-east-

Alpinia bracteata belongs to a group of rather closely

allied species, and most resembles A. nutans, Rose., which is

readily distinguished by its more compound inflorescence,

and A. Henryi, K. Schum., which has the indumentum on

the rhachis more silky in texture. It must not be

confounded with the species described as A. bracteata by

Roscoe in the Transactions of the Linnean Society, vol. xi.”

p. 281 (1815) “from a Chinese drawing belonging to the

Right Hon. Lord Stanley, F.L.S.” which has been referred

by Schumann both to A. alata, A. Dietr., and also, as Mr.

Wright points out, to A. calearaia, Roxb.

The plant from which the figure now given was made,

was raised at Kew from seeds received from the Royal

Botanic Garden, Calcutta, in 1882. It flowered at Kew for

the first time in a tropical house in May, 1908. The species

Fesruary, 1909,

= i in. long. Corolla-tube funnel-shaped, } in. long; lobes

was, however, first introduced to European cultivation in

1820, and a plant had already flowered at Kew in 1864.

Cuntivation.—The species now figured, like the other

Alpinias, thrives well when grown as a swamp plant in a

strong loamy well-manured soil with a constant supply of

moisture and a high temperature. An ideal place for such —

plants is a tropical aquatic house where the soil about the

roots can be kept in a mud-like condition while the stems

are exposed to abundant sunshine. The flowers of the

various species of Alpinia are somewhat fugacious, but while

fully open they are very effective.

Descrietion.—Herb ; perennial. Stem erect, 3-7 ft. high.

Leaves up to 2 ft. in length, 6 in. wide, ovate-oblong, the

uppermost lanceolate, acuminate, glabrous above, paler and

tomentose beneath, the margins closely ciliate ; leaf-sheaths

about 8 in. long with an obtuse, glabrous ligula; petioles

2 in. long. Racemes terminal, erect, simple, 5-8 in. long,

The genus Oligobotrya is intermediate between Smilacina,

of which it has the habit and the terminal inflorescence,

and Polygonatum, with which it agrees in having a gamo-

phyllous perianth. The specimens on which the original

description of O. Ilenryi was based were sent to Kew in

1886 by Mr. A. Henry, who had obtained them at Patung

in Hupeh, Central China. Since then the species has been’

met with in the adjoining provinces of Hunan and Szechuan.

The specimens here figured were received from Messrs. J.

Veitch & Sons, for whom it had been obtained by Mr. E. H.

Wilson. The original description states that the leaves are

glabrous, but Mr. Wright finds that although the leaves of »

the specimens first communicated bear comparatively few

hairs, these are not entirely absent. In other specimens,

however, the leaves bear numerous hairs as shown in the

figure. Some of the wild specimens in the Kew collection

are of very vigorous habit and have a much-branched

inflorescence.

Frsrvuary, 1909.

Curivation.—The plants from which the plate here

given has been prepared were grown, Messrs. Veitch

inform us, at their Coombe Wood Nursery in a very shady

and moist border of leaf-mould and peat. They find that

the same treatment as that accorded to the hardy Cypri-

pediums appears to suit this plant.

Descriprion.—ferb. Stem erect, sometimes over 3 ft.

high, 3 in. thick, flexuous, green with purple blotches,

pubescent. Leaves sessile or shortly petioled, ovate-oblong

or ovate, shortly acuminate, rounded at the base, many-

nerved, more or less pubescent especially on the nerves,

4 in. long, 14-2 in. broad. Racemes terminal, simple or

branching ; pedicels slender, ~y in. long; bracteoles very

small, ovate, pubescent. Perianth usually white or pale

yellow, or (var. violacea) with violet tube and pale violet

lobes ; tube cylindric, } in. long, } in. wide, base truncate ;

lobes spreading, oblong-ovate, obtuse. Stamens adnate to

corolla-throat ; filaments very short ; anthers oblong, obtuse.

_ Horticulture is indebted to Col. R. H. Beddome for the

introduction of this distinct species, raised by him from

seeds received from Northern India. Its original discovery

is attributed to Sir G. Watt, to whom it has been dedicated

by Col. Beddome in the original description, accompanied

by a good figure, in the Gardeners’ Magazine for 1901.

No precise locality is given for the wild plant. In habit it

most resembles /. nervosum, figured in this work (t, 1358)

as Justicia nervosa.

The use of the name Hranthemum for the genus to which

these two species belong is explained by Dr, Stapf as

Fesruary, 1909.

follows. In recent works the name has usually been

applied to a group of forms not closely allied to the original

Eranthemum of Linnaeus. A century ago R. Brown

pointed out that the Hvanthemum of Linnaeus in the Flora

Zeylanica and in all the editions of that author’s Genera

Plantarum is a Ceylon species allied to Vahl’s Justicia

nervosa and J. rosea (Hranthemum nervosum and E. roseum).

To this Ceylon plant Linnaeus, in his Species Plantarum,

owing to some confusion of synonymy, gave the inappro-

priate name /. capense. Roxburgh, like Brown, had also

taken up Hranthemum in the sense of the Flora Zeylanica,

describing as EL. montanum the plant which Linnaeus had

already termed LE. capense.

The conception of Eranthemum as a genus based on

E. capense, Linn. (E. montanum, Roxb.), was accepted until

1865, when T. Anderson revised the Indian Acanthaceae.

Anderson, some years before, had established a genus

Daedalacanthus on a Ceylon plant which he knew to be

EE. montanum, Roxb., but did not know to be also the species

(E. capense, Linn.) on which Eranthemum, Linn., was |

based. When, in his subsequent revision, Anderson with

good reason broke up into two genera the incongruous

ageregate of forms till then included in Kranthemum, he

placed in Daedalacanthus all the congeners of D. montanus,

T. And. (£. capense, Linn.), on which Eranthemum, Linn.,

had been founded, and retained the name Lyanthemum for

the residual species none of which had been included in |

Evranthemum by Linnaeus. =

The confusion thereby created was pointed out in 1883

by Radlkofer who, in reverting to the usage of Brown,

~ Roxburgh and Linnaeus himself as regards Hranthemum

proper, proposed for the new Lranthemum, T. And. (not of

Linn.), the name Pseuderanthemum. This rectification was

overlooked at the time, but has since been repeated by

Lindau.

The error has mainly been limited to descriptive works;

in horticultural literature Anderson’s separation of the

genera has not always been recognised, and the name

FEranthemum is still in common use for the congeners of

the plant now described. This separation is nevertheless

necessary, for while the two genera have somewhat similar

corollas—a circumstance which may explain their treatment

as one genus until Anderson pointed out how they differ—

their characters are so distinctive as to place them in

different tribes. Hranthemum, Linn., one of the Luellieae,

has contorted corolla-lobes and foveolate pollen ; Pseuder-

anthemum, Radlk., one of the Justicieae, has imbricate

corolla-lobes and banded pollen. ‘There is another and

more obvious, though less important, difference in the bracts ;

in Eranthemum these are usually large, in Pseuderanthemum

they are very small. :

Cutrivation.—The species of Hranthemum are easily

cultivated in a warm house. They are best raised annually

from spring-struck cuttings, and if the tops be pinched back

during the growing season they quickly form shapely little

pot-shrubs and flower freely. The well-known /. nervosum

flowers in winter; the species here figured is at its best in

July and August.

Descriprion.—Jderb ; perennial. Stem branching, angled,

8-10 in. high. Leaves ovate, shortly acuminate, base

shortly cuneate or rounded, 24-4 in. long, 14-24 in. wide,

rather firm, dark green, main-nerves 8-9 pairs and secondary

nerves conspicuous beneath, margins and nerves beneath

slightly scabrid; petiole 1-1} in. long, somewhat winged

upwards. Spikes paniculate, at first about j in., ultimately

23 in. long, dense; lower bracts ovate, upper narrower,

bracteoles whitish, narrow-lanceolate, } in. long. Calyx

filaments very short; staminodes minute, inserted above the

stamens. Ovary and style glabrous; stigma reaching

young, however, the bark is dark smoky-brown with dull

greyish patches where it has flaked off. It is specifically

most nearly allied to P. Gerardiana, Wall., from which it

is distinguished by its whiter bark, rather shorter and

somewhat stouter leaves, and male catkins that form a

compound terminal spike instead of being clustered below

the apex of the branchlets. These two species, with

P. chihuahuana, Engelm., and P. Lumholtzii, Robins. &

Fern., form a small group which the late Dr. Masters looked

upon as distinct from the other species of the genus owing

to the deciduous leaf-scales and the leaves in bundles of 3

with minutely serrulate margins.

Frsruary, 1909.

Cunrivation.—The Pines at Kew as a whole succeed

better and resist the evil influences of London smoke and

fog more successfully than the majority of Conifers do, and

P. Bungeana, which has long been in cultivation, is no

exception to this rule. This species grows very well in the

ordinary gravelly soil characteristic of that part of the

Pinetum in which it is planted. At Kew the trees assume

in habit two distinct forms; an erect pyramidal form and a

rounded bushy one. The figure here given was prepared

from a tree of the former type, which is now 25 ft. high,

with a trunk 23 inches in girth at 3 ft. from the ground.

The trunk is covered with a smooth bark which peels off

very much after the manner of the common Plane. A

distinct and striking tree, P. Bungeana is also attractive

from the deep vivid green of its foliage.

Descriprion.— Tree, 60-100 ft. high; crown pyramidal

or ovoid; stem often dividing low down into erect or

ascending branches; young bark tawny with grey patches,

old bark whitish flaking; young branches greenish-brown,

smooth. Leaves in threes, rigid, 2-4 in. long, yg in. wide,

keeled below, convex above, with finely serrate margins,

dark green and somewhat shining; fascicles at times sub-

verticillate, their bases clothed at first with lanceolate, acute,

brown, membranous deciduous scales 4-4 in. long. Male

catkins numerous, {—} in. long, aggregated in compound,

bracteate, terminal spikes 3-2} in. long; bracts }-} in.

long, wide ovate, cuspidately acuminate and recurved at the

tips, pale brown, shining, submembranous. Cone when

mature 14-2 in. long, 14-14 in. across, ovoid-conical ; scales

obovate, transversely rhomboidly thickened at the tips,

transversely keeled and shortly reflexed mucronate. Seeds

when young slightly winged; when ripe wingless, } in.

long, } in. wide, compressed, ellipsoid or almost orbicular,

pale brown.

The plant from which our figure was prepared was pre-

sented to Kew in the autumn of 1905 by Mr. M. L. de Vil-

morin, in whose collection of shrubs at Les Barres the

original specimen is now a wide-spreading bush or small

tree about 10 ft. in height. S. Vilmorini is very distinct

from the other species of the genus now in cultivation and

is certainly one of the most elegant. It is a native of

Szechuan and Yunnan in South-western China, whence

specimens, collected on the summit of Mount Omei, were

sent to Kew by the Rev. E. Faber in 1887; others from

the same locality were communicated by Mr. A. Henry a

few years later, and still others from near Tachienlu were

received from Mr. A. E. Pratt. |

Schneider has enumerated thirty-four species of Sorbus

as now in cultivation, seventeen of these being members of.

the section Aucuparia. He recognises two varieties of

S. Vilmorini, a typical variety to which the plant here

figured belongs, and a variety, var. setschwanensis, with

Frepsrvary, 1909.

smaller and more numerous leaflets, which approaches so

closely to S. microphylla (Pyrus microphylla, Wall.), a native

of Sikkim, that it might readily be regarded as a geogra-

phical form of that species. :

Cuirivation.—The Kew plant of S. Vilmorini, now a

bush about 6 ft. in height, has grown well in a border of

loamy soil. It forms a most attractive object in early June

when the elegant pinnate foliage is at its best and every

shoot bears a terminal corymb of pretty white flowers.

The fruit is in good colour by September, and the seeds

should afford a ready means of propagating what is one of

the most attractive of the new shrubs received from China

in recent years.

Drsoription.— Shrub or small tree, 10-20 ft. high;

branches striate, glabrous or sparingly rusty-pubescent ;

buds ovate, acuminate, with somewhat pubescent tips.

nearly glabrous; leaflets in 9-14 pairs, opposite or sub- —

C’. Micholitzi: that the two may prove to be forms of the same

species. C. Micholitziiisa sigadh Si of a small group, confined

to an area which extends from Nepal to Annam, in which

the margins of the carpophylls are pectinate. The original

plants were described by Mr. Micholitz as having the stem

Maron, 1909,

subterranean, but the imported stems now in cultivation at

Kew, and shown in plate 8242, are similar in habit to those

of other species of Cycas except in being more slender and

in having usually a decidedly thickened base,

Cutivation.—At Kew this species is not unlike C.

pectinata in behaviour, the leaves being practically annual.

It would appear therefore that the conditions most favourable

for its healthy growth are a liberal allowance of root-room,

a good loamy soil, a plentiful supply of water whilst the

leaves are being formed, and a tropical temperature with

abundant sunlight. In winter the soil about the roots

should be kept drier. :

Description.—Stem sometimes subterranean, 8 in.—2 ft.

in height, 13 in. thick above, sometimes 4 in. thick at the

base. Leaves 2-3, terminal, erect, 8-10 ft. long, their lower

third beset with short rather flat yellow spines, elsewhere

bearing two rows of subdichotomous pinnules 8 in. long and

13 in. apart, their segments green above, paler beneath,

3-1 in. wide, usually again divided. Male cone narrow-

T. A. SPRAGUE.

In 1905 (B. M. t. 8058) a figure was given of the form

of S. scardica that is most usually met with in alpine

gardens. This figure was accompanied by a description

applicable to the species as a whole, and it was pointed out

by Mr. Sprague that the form there figured is not the

typical state of the species. It did not then, however,

appear desirable to press the point, or to suggest the

recognition in the plant figured at t. 8058 of a new variety,

more especially as Halacsy had recently (Consp. Fl. Graee.

vol. i. 1901, p. 598) interpreted the species in a very wide

sense.

_ To Mr. R. Farrer, of Ingleborough, English horticulture

is we understand indebted for the introduction of the rare

typical S. scardica, a living plant of which was presented to

Kew in 1908 by Mr. E. H. Jenkins of Hampton Hill. When

this plant was grown alongside the form figured in 1905 it

was evident that the latter is well entitled to the rank of

a variety. The differences exhibited by the two formsmay be

briefly stated. In S. scardica proper, here figured, the lower

Marcu, 1909,

leaves are acute, with 9-15 intramarginal pits; the 3-11-

flowered stems are reddish, and the reddish, subacute calyx-

lobes are distinctly glandular-pilose. In the form figured at

t. 8058, for which Mr. Sprague proposes the name S.

scardica, var. obtusa, the lower leaves are subacute, with 5-11

intramarginal pits; the 1-3-flowered stems are green, and

the green, obtuse calyx-lobes are relatively free from

pubescence.

Cuurivation.—Like its variety obtusa, the typical

S. scardica is quite hardy at Kew, and has flowered

freely, standing a moist atmosphere better than some of the

Saxifragas of similar habit which are grown under the

conditions that prevail in the Rock Garden.

Descriprion.—/Herb, densely tufted. Leaves below

spreading, oblong, acute, 1-2 in. long, ;)—} in. wide, rigid,

somewhat concave above, convex and when dry keeled

below, with cartilaginous edges ciliate towards base and

serrulate upwards, submarginal pits 9-15. Stems bearing

flowers erect or ascending, 3-44 in. long, corymbosely

3-11-flowered, glandular-hairy, reddish; leaves scattered,

glandular ciliate except towards apex. Calyx glandular-

hairy outside; lobes ovate, subacute, about } in. long.

Pseuderanthemum seticalyz, the species now figured, is a

native of Nyasaland where it was first discovered by Dr.

(now Sir J.) Kirk fifty years ago. The specific name has

reference to the attenuate calyx-lobes, not to the presence of

setae, for the calyx is glabrous or nearly so. For seeds of

this species Kew is indebted to Mr. J. M. Purves, who

obtained them on the Fuchila Plateau, Mlangi, British

Central Africa, at an altitude’ of 6,000 ft., in 1904; the

resulting plants flowered in March, 1905,

Marca, 1909.

An explanation of the nomenclature and _ systematic

position of the genera Eranthemum and Pseuderanthemum

has already been given in this work (B. M. t. 8239). The

genus Pseuderanthemum comprises between 60 and 70

species, inhabiting the tropics of both hemispheres ; they

are most numerous in the Indo-Malayan and Polynesian

regions. The genus is very homogeneous, and the species

much resemble each other in general appearance.

Cuirivation.—The treatment most suitable for a large

number of subtropical <Acanthaceae answers well for the

species here described. Cuttings are put in early in spring ;

the plants are grown on under liberal treatment, and the

growths are stopped as often as is necessary to make them

bushy. Plenty of sunshine and moisture must be allowed

while growth is being made. Many of the species of

Pseuderanthemum may be grown so as to get them in flower

in winter, when they are of considerable decorative value.

Among those best suited to this purpose are P. albiflorum,

Radlk. (B. M. t. 4225); P. Andersonii, Lindau (B. M. t.

5571); P. cinnabarinum, Radlk. (B. M. t. 5921); P. igneum,

Stapf (Eranthemum igneum, Linden); and the species now -

figured, which last may also be grown so as to flower in late

summer.

Description.— Undershrub, erect, lax, somewhat hirsute

with stiffish white hairs; branches terete. Leaves ovate,

acuminate, base contracted and cuneately decurrent, 2-5 in.

long, 14-34 in. wide, thin, dark green, sparingly hairy, main

nerves oblique, 6—7-paired ; petiole slender, 2-1} in. long.

Inflorescences spiked, terminal or also in upper leaf-axils, at

first dense, afterwards elongating and interrupted below,

ultimately 4 in. long, when young comose from the slender

calyx-lobes and bracts; rhachis somewhat hirsute; cymes

3—l-flowered, sessile; pedicels rather thick and short or

obsolete ; bracts subulate, sparingly whitish hirsute, ¢ in.

long, bracteoles similar but smaller. Calya } in. long,

glabrous or nearly so, deeply 5-lobed, lobes slender subulate.

Corolla salver-shaped; tube narrow, nearly straight, pale

red, sparingly glandular hairy; limb cinnabar red above,

paler beneath, 1 in. across; lobes oblong or subobovate

obtuse nearly 4 in. wide. Anthers slightly exserted ; fila-

ments 4'g in. long. Capsule glabrous, clavate, 1-14 in. long,

about 4 in, wide above, with a narrow stipe }- in. long;

fertile portion laterally compressed and somewhat constricted

between the seeds. Seeds lenticular, }~1 in. long, toothed

near the base, smooth on one side, corrugated on the other,

with a blunt margin.

Nigella integrifolia has been in cultivation at Kew since

~1894 when seeds were received from the Imperial Botanic

Gardens, St. Petersburg; specimens in flower were also

received in July, 1907, from Mr. W. E. Gumbleton. Four

of its congeners have already been figured in this work :

N. damascena, Linn. (t. 22); N. orientalis, Linn. (t. 1264);

N. hispanica, Linn, (t. 1265), and the inconspicuous WN.

Garidella, Spenn.; the last named appearing (t. 1266)

under the name Garidella Nigellastrum, Tae. From these

and all the other species of Nigella the plant now figured is

readily distinguished by its bell-shaped flowers which

strongly resemble those of a Campanula.

Mazrcg, 1909.

Cuitivation.— NV. integrifolia is grown as an annual

and thrives quite as well as the elegant Love-in-a-Mist (WV.

damascena) or the Spanish Fennel-flower (NV. hispanica)

under the treatment .suitable for these species. The seeds

are sown under glass in early spring, and the young plants

are transferred to the open border in May.

Desoription.—Herb, annual, slender, very sparingly

puberulous; wild plants erect, little branched, rarely over

1 ft. high; cultivated examples more slender, weaker,

somewhat spreading, much branched, 13-2 ft. long. Leaves

at base linear-spathulate, entire, 4 in. long or longer; lowest

stem-leaves entire, linear, acute, the rest subsessile, 3-9-

palmatipartite, lobes very narrow, very acute, usually 1}—

2 in. long, the uppermost involucrate round the solitary

flowers. Flowers blue, campanulate, 3-1 in. long. Sepals

usually 5, petaloid, oblong, closely applied by their margins,

tips rounded, slightly recurved. Petals or nectaries usually

8, linear, bifid half-way, obscurely ciliate, nectariferous at

the base within. Stamens about 20. Carpels usually 3,

about 2 in. long, connate above the middle, shortly beaked ; —

beaks hardened, spreading. Seeds trigonously compressed,

rugose, 3-ribbed behind, whitish. ..

The plant from which the figure now given has been

prepared was purchased: from Mr. Spith of Berlin’in 1900

under the garden name of R. moriifolius ; it differs, however,

from Siebold’s species so named, and Dr. Focke has found

it necessary to treat it as a distinct species referable to a

small East Asian group, the Corchorifolii, of the section

Batothamnus. To the same group belong &. corchorifolius,

Linn. f.; R. crataegifolius, Bunge; and R. palmatus,

Thunb., which has already been figured in this work (B. M.

t. 7801). It is considered by Dr. Focke to be most nearly

allied to R. incisus, Thunb., from which it differs in its more

robust habit and in the larger size of all its parts.

Cuitivation.—R. Koehneanus at Kew has proved per-

fectly hardy and has formed a rounded bush 3 ft. high.

It blossoms towards the end of May and its fruits are ripe

in July. The plant thrives vigorously in a border of

Mascu, 1909.

loamy soil, and can easily be increased by means of suckers.

Its attractions as a shrub for the garden lie in its fine

lobate leaves and in its abundant, pretty and distinct

flowers.

Description.—Shrub, suberect, 3-4 ft. high; branches

again branching, somewhat striate, with a purplish bloom,

smooth or sparingly prickly. Leaves petioled, simple, 3—5-

lobed or sometimes almost entire, crenate or toothed, 14—5 in.

long, #-5 in. wide, base usually deeply cordate, the lobes

acute or subacute ; green above, white-pubescent beneath,

Impatiens Hawkeri is one of the only two species of

Balsamineae hitherto discovered in New Guinea, the other

being the closely allied J. Herzogit, K. Schum. (? = J.

cordipetala, Zipp.). These are the most easterly members

of the family in Asia, from which continent and its islands

about 500 species are preserved in the principal European

Herbaria. The most remarkable feature of these Asiatic

species, Sir Joseph Hooker points out, is the very restricted

geographical area to which they are confined. There are

five such areas, each of great extent: the Himalayan; the

Burmese, including Assam; the Western Indian Peninsular,

including Ceylon; the Chinese; the Malayan, from Sumatra,

- Java and Borneo eastward to New Guinea and the Philip-

pines. No two of these areas contain more than half-a-

Apri, 1909.

dozen species in common and one species alone, 7. Balsamina,

Linn., the origin of the garden Balsam, is a native of all.

The plant now figured is a native of the last mentioned

area, in which about 60 other species have been found; of

these species I. platypetala, Lindl., from Java, is a typical

member. Salient characters of these are the whorled leaves

and simply pedicelled flowers met with in many of them,

together with more or less obcordate standard and wing-

lobes, a long spur and very short filaments with confluent,

broad, nearly erect, introrse anthers.

_ I. Hawkeri was discovered by Lieut. Hawker, R.N. ‘There

is a specimen in the Kew Herbarium, which was received

in November, 1884, from Dr. Schomburgk of the Adelaide

Botanical Gardens—some two years prior to the earliest

publication of the name—ticketed as from Lieut. Hawker

and as native of one of the South Sea Islands, the name of

which was forgotten. From this it appears that in all

probability the plant was first raised in Adelaide and thence

transmitted to Mr. Bull, of Che'sea, in whose catalogue it

was included for the first time in 1886. A second herbarium

specimen was communicated by Messrs. Veitch in 1897; it

was collected by Mr. Burke. A third was sent from the

Singapore Botanical Garden, ticketed as from “EK. Brit.

New Guinea, W. Micholitz, 1898.” There is also a specimen

in the British Museum Herbarium, cellected by Mr. H. 0.

Forbes “near South Cape on the mainland.”

In Mr. Bull’s Catalogue /, Hawkeri was described as a

handsome species of free growth and good habit, flowering

in great profusion from March until October. For a time

it enjoyed considerable popularity, but it suffered so

frequently from attacks of the Begonia mite ( Tarsonymus)

that it went almost entirely out of cultivation, When in

good health it grows vigorously, forming a shapely plant

about 2 ft. high, well furnished with leaves and flowering

freely and continuously during the summer. It requires

tropical conditions with plenty of atmospheric moisture and

shade from bright sunshine.

The genus Microloma, which is endemic in South Africa,

includes ten species, most of which are confined to the

Central and Western Regions of Cape Colony. The leading

exceptions are M. sagittatum, R. Br., which is common in

the Coast Region as well as in the Western, and the species

now figured, which appears to be confined to the Coast

Region but is widely distributed therein from the Van

Rhynsdorp to the Port Elizabeth Divisions. Mr. Brown

points out that the only species with which M. tenuifolium

might be confused is M. namaquense, Bolus, a species

restricted to the Western Region, in which the deflexed

tufts of hairs are situated near the middle of the corolla-

tube. The remaining species have the corolla-lobes more or

less laterally compressed, longer than broad and often

dorsally gibbous.

ArriL, 1909.

M. tenuifolium, the Coral Climber of South Africa,

though it can be grown at Kew, never succeeds satis-

factorily under the conditions that obtain here, and we

are indebted to Mr. W. E. Gumbleton for the specimen

now figured which was grown in his garden. In a note

in the Gardeners’ Chronicle for 1908, vol. xlii. p. 79,

Mr. Gumbleton records the receipt of three healthy well-

grown plants of this species from Port Elizabeth, where it is

found growing wild at the base of low scrubby bushes

round the branches of which it twines its slender, wire-like

stems. The evidence to be obtained from herbarium

specimens indicates that the wild plant flowers more

profusely and bears more brightly coloured corollas than is

the case in this country. These flowers, which are waxy

and Hoya-like, are produced in axillary bunches. The plant

requires greenhouse conditions.

Under the name of Arbutus procera this handsome

evergreen tree was introduced into this country by the

Horticultural Society of London through their collector,

David Douglas, in 1825. It appears never to have become

common, and the specimens usually seen have not reached

any considerable size. Mr. Elwes, however, records some

fine trees known to him, the largest being that in the

gardens of Mr, J. R. Anderson, at Bassetwood, near

Southampton, which is 50 ft. high.

Aprin, 1909.

The species, which bears the vernacular name of Madrona,

is distributed from the British Columbia coast at Seymour

Narrows southward through the coast region of Washington

and Oregon, and through the California coast ranges to the

Santa Lucia Mountains. Professor Sargent describes it as

the noblest of all its race, and refers to a magnificent

specimen growing on the slopes of Mount Tamalpais, near

the town of San Rafael, Marin County, California, which is

upwards of 100 ft. high and has a trunk measuring 23 ft.

in girth at 3 ft. from the ground. Aon illustration of this is

given in the Garden and Forest, vol. v. p. 151. South of

the Bay of San Francisco Arbutus Menziesii is often

shrubby. Its heavy, hard and close-grained wood is used

in the making of furniture, and largely also in making

charcoal for gunpowder.

Arbutus Menziesii is one of the few hardy Ericaceous

plants which attain to tree-like dimensions in this country.

The specimen from which the flowers figured in the

accompanying plate were taken has stood for many years

on the north side of the Broad Walk at Kew. It is

now a spreading, bushy tree about 20 ft. high, with a short —

trunk 4 ft. 8 in. in girth. It has an interesting and

conspicuous appearance because of its smooth cinnamon-

coloured branches. The species is quite hardy at Kew,

although the shoots of young seedlings, which grow

vigorously and late into the autumn, are apt to be cut back

by frost. Plants should be given a permanent place early,

because of their impatience of disturbance at the root.

Once established, they grow quickly. The soil should be of

a peaty nature or, failing that, a sandy loam.

Drscriprion.— Tiree, stem 20-50, rarely up to 110 ft.

high, 1-4 or sometimes up to 7 ft. in diameter, bark generally

or at least partly flaking as it also does on the larger

branches, then very smooth and cinnamon-coloured ; crown

spreading ; young twigs pale red, orange or green, smooth

or sparsely clothed with hairs that soon disappear. Leaves

elliptic or oblong, 24—5 in. long, 14-3 in. wide, apex rounded

or shortly cuspidate, base rounded, subcordate or cuneate,

entire or sometimes (especially in young specimens) serrate,

coriaceous, dark green, shining above, glaucous beneath;

petioles thick, channelled above, 3-1 in. long. lowers in

erect, terminal, puberulous panicles 5-6 in. across; pedicels

1_1 in., in fruit 2 in. long; bracts scarious, ovate, shorter

than the pedicels. Caly« whitish, small, scarious, 5-lobed.

Corolla white, urceolate, about + in. long. Filaments pilose,

dilated at the Lase; anthers recurved, biaristate, the connec-

tive rather longer than the anther-cells. Ovary glabrous,

2-celled; cells many-ovuled. /’ruit drupe-like, granular,

usually subglobose, bright orange, 4-3 in. long.

Strophanthus Preussii is a species which extends from the

Gold Coast to Angola and eastwards to the Middle Congo,

It is closely allied to S. Barter’, Franch., from Lagos, but in

that plant all the sepals are narrow and rather spathulate.

It has been identified by Dr. Gilg with S. bracteatus,

Franch., a species of which there is no authentic specimen

at Kew. Dr. Stapf however explains thatthe description

originally given of S. bracteatus points to that plant being

distinct from S. Preussii. According to Franchet, 8S.

bracteatus has glabrous inflorescences and white corollas

streaked with red, while the tails of the corolla-lobes are

only 10-12 em. long. The figure here given has been

made from a specimen which flowered in the tropical

ApriL, 1909.

collection at Kew. The description now for the first time

given of the follicles and seeds has been based on a specimen

collected in Lagos and communicated to the Kew herbarium

by Sir T. R. Fraser, Edinburgh.

Strophanthus Preussii is grown as a_ stout climber

against the roof of the Palm House at Kew. It was raised

from seeds forwarded in 1902 by Mr. W. H. Jolinson,

from the Botanic Station at Aburi, Gold Coast. It

flowered for the first time in July, 1908. As a garden

plant it is not so attractive as the South African S. grandi-

florus (B. M. t. 7390) formerly treated as a varicty of S.

Petersianus, or as S. gratus (B. M. t. 4466) formerly known

as Loupellia grata. ‘These are all tropical climbers which

grow freely when planted in a loamy soil and afforded

ordinary tropical house treatment.

Descriprion.—Shrub, climbing or straggling; stems up

to 12 ft. long, branches glabrous, brownish with white

Anthurium trinerve is a native of Brazil and Guiana, in

which countries it is not uncommon. It is very nearly

allied to A. violaceum, Schott, but it usually has broader

leaves than that species; the stem too is rather more robust

and is more densely clothed with the fibrous remains of the

cataphyllary leaves. The chief distinction, however, as

Mr. Brown points out, is that the ovary in A. trinerve

tapers into a conical style-like portion exserted far beyond

the sepals; this feature is absent from A. violaceum. It is

1o be noted that the species here described must not be

confounded with the similarly named A, trinervium, Kunth,

a plant totally different in appearance, with much larger,

cordate leaves. The plant from which the figure now given

has been prepared has long been in cultivation at Kew ; it

flowers freely every year and fruits copiously, the flowers

being evidently self-fertile, i

Aprin, 1909,

From the cultural standpoint A. trinerve is interesting

among the many species cultivated at Kew as being one of a

group the members of which are attractive on account of the

bright colour of their fruits. Foremost among these stands

A. Bakeri, Hook. f., figured at plate 6261 of this work, —

which has bright crimson berries. ‘Two members of the

group, A. violaceum, Schott, alluded to above, and A.

margaritaceum, Baker, agree with the species now figured

in haying lilac berries. The cultural requirements of the

plant are those suitable for <A. Scherzerianum, Schott

(B. M. t. 5319), and a number of other well-known species

that are grown as ornamental stove-plants.

A recent addition to the genus, D. Bronckartii is most

closely allied to the familiar D.-thyrsiflorum, Reichb. f., but

is readily distinguished by its larger size, its ampler and

laxer inflorescence and its light rose-coloured flowers. The

species was introduced from the mountains of Annam in

Indo-China by the collector whose name it bears, and the

plant from which the drawing now given has been made

was purchased in 1906 from Mr. Verdonck of Ghent.

_ Its general resemblance and evident aflinity to D. thyrsi-

Jlorum had led to its cultivation under the conditions suitable

for that species; abundance of heat and moisture, with very

little shade during summer when the plants were in growth,

an intermediate temperature with very little moisture from

October until the flower-buds showed signs of activity, when

a good soaking at the root and tropical conditions were

again afforded. Like D. thyrsiflorum, D. densiflorum, D.

Farmeri and the other members of the same group, this

species is remarkable for its large, handsome flowers disposed

in decurved racemes. It is a striking addition to the group,

and as, like the other members, it is not difficult to grow,

it ought to share their popularity as garden orchids.

Lariz occidentalis, according to Professor Sargent, was

first observed by Lewis and Clark in the forests of the upper

Clearwater River. It was seen also by D. Douglas in 1827

near Fort Colville on the upper Columbia, but was mistaken

by him for the European Larch. Thomas Nuttall therefore

is to be regarded as its real discoverer; he collected it in the

Blue Mountains in 1834 and first described it in the place

cited above. It was first planted in the Arnold Arboretum

in 1881 and a number of seedlings were sent to Kew by

Professor Sargent in the autumn of that year. From one

of these, which is now a tree 36 ft. high with the trunk

26 in. in girth near the ground, and is one of a group in

the Pinetum at Kew, the figure now given was prepared.

Considerable interest is at present being taken in this

American Larch by British foresters ; it is hoped that it may

May, 1909.

prove useful as a substitute for the European Larch, whose

value in many districts is impaired by its susceptibility to

the attacks of Peziza Willkommii. The rate of growth

indicated above may not compare favourably with that of the

average Kuropean Larch in British plantations, but when the

dryness and poorness of the soil in which the trees grow are

taken into account, the figures afford a not unfavourable

augury for the success of the species as a forest tree in Britain.

The trees at Kew fruit freely, but the cones have never yet

been found to contain fertile seed. A tree in the garden of

Mr. P. L. de Vilmorin at Verriéres-le-Buisson, near Paris,

also cones freely but has never yet given good seed. Larix

occidentalis does not appear to be so hardy as L. europaea.

According to Mr. Hesse it has proved too tender to be worth

growing at Weenen in north-west Hanover, where the

European Larch succeeds. It is, however, quite hardy at

Kew.

Drscription.— Tree, often reaching 250 ft. in height,

with a stem 6-8 ft. thick, and with a small narrow-

pyramidal head ; in British collections the largest examples

as yet hardly exceed 36 ft. in height; branches dimorphic,

the abbreviated branchlets many-leaved. Leaves very

narrow, quadrangular, 2-suleate on both faces, acutely and

widely keeled beneath, those of the abbreviated branchlets

the longer and sometimes, as here shown, 2-23 in., but

often only 14-14 in. long, 1} lin. wide; those of the

sterile twigs more rigid and }-% lin. wide, all usually

2-canaliculate. Male flowers in yellow, subsessile, subglobose

clusters, about 2? in. across, surrounded by broad reddish

floccose-ciliate scales or bracts. Female flowers in ovoid-

oblong cones about # in. long. Carpels about 2 in. long,

recurved, acute, the tips long, green. Scales bearing ovules

nearly orbicular, 1-14 lin. wide. Ripe cones subsessile,

suberect, oblong-cylindric, rather variable in size, the largest

up to 1} in. long, brown; carpels tailed longer than the

Mussaenda Treutleri, to which Dr. Stapf has now for the

first time accorded its proper status as a distinct species, is

an old and well-known garden plant. It was originally

discovered by Dr. Wallich in the mountains of Nepal, but

was at first mistaken for a form of Mf. frondosa, and issued

by him under that name in the Hon. E. 1. Company’s Herb-

arium (Cat. Lith. 6250 E in part), but was subsequently

confused with Jf, macrophylla, under which erroneous name

it is usually cultivated. In the Flora of British India,

(vol. iii. p. 90) Sir Joseph Hooker first pointed out that it is

distinct alike from M. macrophylla and M. frondosa; it is

there treated as a variety, var. grandifolia, of the latter.

May, 1909.

A note on the relationships of these three plants and their

immediate allies will shortly appear in the Kew Bulletin.

M. Treutleri was introduced into cultivation by Messrs.

Knight and Perry about 1840. It flowered with them in

1844 and again in 1845, and was figured both in the Botanical

that it was MZ. macrophylla, Wall. The area of the species

extends from Lower Nepal to Sikkim and the Khasia Hills

at elevations of from 2,000 to 6,000 ft. above sea-level. In

Sikkim it was collected by Sir Joseph Hooker in 1848, and

again by Dr. Treutler in 1860, in dense forest below Birch

Hill, near Darjeeling.

At Kew M. Treutleri is grown as a stove-plant and

forms a shrub about 3 ft. high, with numerous branches

which produce terminal heads of flowers in July and

August. After flowering the plants are rested dry, and are

started into growth again in spring by the application of

heat and moisture. Seeds do not mature, but cuttings of

the young shoots readily strike roots,

Descriprtion.—Shrub, branches shortly pubescent upwards.

Leaves ovate or ovate-elliptic, shortly acuminate, usually

shortly cuneate at base, 6-12 in. long, 3-6 in. wide, hirsute

on the nerves on both sides, especially beneath and on midrib,

elsewhere sparsely harshly hairy ; petioles 3-1} in. long;

stipules wide-ovate or triangular, acuminate, often 2-fid, 31-3

in. long, } in. wide, herbaceous. Corymbs many-flowered,

dense, terminal, often with additional cymes in the upper

axils; lower bracts broad, sometimes slightly laciniate, upper

bracts like sepals; pedicels very short. Sepals linear or

subulate, much and gradually narrowed, herbaceous, almost

glabrous except the setose-ciliate edges, }-? in. long, 4-3 lin.

wide, or rather wider; leafy sepal white, otherwise like the

leaves. Corolla before opening 3-1} in. long, adpressed

pubescent, when old often almost glabrous; limb orange, in

bud 5-horned, the horns often rather long; lobes } in. long

and broad with slender caudate tips; tube with a lining

of orange hairs in the throat. Berry globose, dry, 4 in.

across, soon glabrescent. |

Lemoine in Gard. Chron. 1898, vol. xxiv. p. 265.—J. Hutcninson.

Deutzia setchuenensis is closely related to the Himalayan

D. staminea, R. Br., but is distinguished from that species

by the larger and more acuminate leaves, the longer lateral

flowering branchlets and the more spreading inflorescences.

The form described as D. corymbiflora, Lemoine, has been

identified by Mr. Franchet with this species; Mr.

Hutchinson, however, points out that Lemoine’s plant, as

figured in 1902 (Rev. Hort. Belge, vol. xxviii. p. 157)

appears to have smaller, less acuminate leaves and pinkish

white flowers,

One of the most beautiful members of the genus, D.

setchuenensis, like many other North Asian shrubs, is often

excited into premature growth by warm days in early spring,

and on this account its young shoots and flower-buds are

frequently destroyed by late frosts. This seriously affects

its value as a garden-shrub, though it is perfectly hardy in

May, 1909.

other respects. The plant from which our figure was prepared

was presented to Kew in 1897 by Mr. M. L. de Vilmorin,

and since then it has never been seriously damaged by

genuine winter cold. It will probably have some value as

a shrub for forcing into early flower for greenhouse decora-

tion, and will certainly prove a charming acquisition in

climates where a sharper line divides winter from spring

than is the case at Kew. Like the rest of the Deutzias, it

thrives in good loam and is easily increased by means of

te made of half-ripened wood. It flowers early in

uly.

It has already been suggested by Dr. Schneider (Ill.

Handb. Laubholzk. vol. i. p. 665) that the tree cultivated in

European collections as Pyrus Pashia, which Decaisne has

distinguished from the typical form of that species as

P. Kumaoni, may be no more than a glabrous variety of

P. Pashia proper. A careful study of the material in the

herbarium at Kew has enabled Dr. Stapf to completely

confirm this view. P. Pashia, taken in its wider sense,

ranges throughout the whole of the temperate Himalaya

from Kashmir to Bhutan, and extends thence to the Khasia

and Naga Hills, to Manipur and northern Burma and into

western China. The form now figured was described by

Decaisne from a specimen collected by Strachey and

Winterbottom in Kumaon between 5,000 and 8,000 ft.

above sea-level, where it is said to be common. The form

which constitutes the type of the species is one with densely

cottony leaves and ealyees, which was collected in Nepal by

May, 1909. ; .

Buchanan (afterwards Hamilton) and again by Wallich

The bulk of the specimens in the Kew herbarium are more

or less intermediate between the Nepal and the Kumaon

forms, the amount and degree of persistence of the tomentum

showing considerable variation.

According to Loudon (Encye. of Trees and Shrubs,

p. 424) P. Pashia was. first introduced into England in

1825, but the precise history of the tree from which the

plate now given was prepared is not known. It has been

growing in the collection of Rosaceae at Kew for many

years; it is a grafted plant, but is in vigorous health, being

now 25 ft. high, 20 ft. in spread of branches, with a

trunk 2 ft. 3 in. in girth. It flowers with all the pro-

fusion characteristic of its kind, but is more attractive than

the majority because of the compactness of its flower-clusters —

and the full-rounded contour of the individual blossoms.

The deep-red anthers, too, show up strongly against the

pure white petals, and the tree is worthy of more notice

from arboriculturists than it has yet received. :

Descriprion.— Tree, small to medium in size, with

branchlets that blacken on drying, glabrous or soon be-

coming so; buds conical, glabrous, }-} in. long. Leaves

ovate tending to rounded-elliptic or ovate-lanceolate, gradu-

ally narrowed or at times obtuse at the tip, rounded at the

base, finely crenulate, usually 2-33 in. long, 14-2 in. wide,

glabrous or soon becoming so, when full-grown papery

very dark green; petioles slender, 13-2 in. long. Corymi

many-flowered, on short branchlets, glabrous or soon b

coming so; pedicels about 4 in. long. Receptacle glabrous

Sepals at length falling off, triangular or ovate, obtuse or

acute, or occasionally apiculate, glabrous without, more or

less cottony-pubescent within, the hairs on their margins

glandular and more persistent elsewhere, sometimes dis-

appearing. Petals at first suffused with pale rose, at length

becoming white. Stamens exceeding 25. Styles usually 5.

Fruit globose or obovoid-globose, brownish green or brown,

dotted with numerous pale lenticels, over 1 in. in diameter. —

The Pine which is here figured was discovered by

J. Jeffrey in the Shasta Valley in North California when

collecting for an Edinburgh association in 1852. Seeds

were sent by him to Edinburgh in the same year, and in a

circular to the subscribers issued by Andrew Murray it is

explained that these were distributed by the committee

under the names given to them by various botanists, the

figures and descriptions of the cones, leaves and seeds of the -

Jung, 1909.

Coniferae included in the report being supplied by

Dr. Greville and Professor Balfour. This report appears

to be rarely met with, and has been little consulted, for the

new species with which it deals have been by some

attributed to Murray, by others partly to Balfour and

partly to Jeffrey. -The coloured plate representing P.

Jeffreyi bears the signature of Dr. Greville. ‘Opinions are

divided as to whether this tree deserves specific rank ; there

is no difficulty in distinguishing the form now described,

the account of which is based exclusively on material from

a tree in cultivation in the Arboretum at Kew, from culti-

vated examples of P. ponderosa, but it is stated that inter-

mediate wild forms have been met with.

Opinions appear to be similarly divided as to the relative

ornamental value of P. Jeffreyi and P. ponderosa, Sir

Joseph Hooker, in the passage referred to above, describes

it, as seen by him in a wild state, as inferior to P. ponderosa

and as by no means a handsome tree; his figure bears out.

_ this judgment. Yet, as met with in cultivation, the longer

leaves and the larger cones serve to render P. Jeffreyt

perhaps the more striking of the two. Though neither of

these near allies can be considered among the handsomest

of Pines, in habit they are both notable in the parks and

gardens of this country for their tall, stately, column-like

trunks—as a rule, perhaps, too thinly set with branches to

- make them perfect specimen trees ; for their deeply fissured,

rugged bark; for their long rigid leaves arranged in a

brush-like cluster on the terminal portion of each year’s

growth ; and, more especially as regards P. Jeffreyi, for the

fine, handsomely coloured cones. Young trees are. best

reared from imported seed.

Descriprion.—Tree, the one here figured about 40 ft.

high, with very stout flowering branches. Cataphyllary

leaves scale-like, lanceolate, 3-1} in. long, narrowly long

acuminate, scarious, brown, shining, finely fimbriate ; leaves

proper ternate, acicular, rigid, 6-10 in. long, pungent,

convex on the back, biconcave and keeled on the face,

margin finely toothed, scabrid, with two marginal resin-ducts ;

sheaths about 14 in. long, truncate, at first silvery, at length

blackish, persisting. Male cones many, at the bases of

- young shoots, each solitary in the axil of a cataphyllary

leaf, densely clustered, involucrate, clavate-cylindric, 14-2

in. long; the cataphyllaries scarious, brown, lanceolate,

very acuminate, fimbriate, 2—$ in. long. Jnvolucral scales

10-12, like the cataphyllaries but smaller, entire and not

acuminate ; anthers very many. female cones spuriously

terminal, solitary, erect, stipitate, the stipe clothed with

many scales; carpels small, at length almost disappearing ;

Begonia modica is a member of the section Seutobegonia,

which includes a small group of species all of them confined

to West Africa from Liberia to the Congo. The species of

this section are small herbs mostly with peltate leaves and

yellow flowers. The plant from which the figure here given

has been prepared was raised from one of a number of tubers

of the species received at Kew in 1907 from Mr. J. Anderson,

Curator of the Botanic Station, Kumasi, who had found them

growing in the Gold Coast Colony on rocky ground at an

altitude of 600 ft. above sea level. Under the treatment

ordinarily accorded to Begonias these tubers developed their

leaves and flowered for the first time in September, 1908.

Descriprion.—Herb, almost stemless. Leaves petioled ;

petioles 14-14 in. long, reddish, hirsute; blades obliquely

softly hirsute beneath, nerves 6-8 radiating from the

petiole which joins the lamina about 3-3 in. from the base.

Peduneles few-flowered, 3-14 in. long, sparingly hairy.

Flowers umbelled, yellow; each umbel of 2 stalked males

and a single subsessile female; the males on glabrous

The Nepalese Whitebeam, sometimes met with in collec-

tions under the garden names of Sorbus nepalensis or Pyrus

nepalensis, is not confined to the country from which its most

familiar name is derived, but extends throughout the temper-

ate Himalaya, at elevations of 8000-10,000 ft. above sea-

level, from Garhwal to Sikkim, According to a manuscript

note placed by Dr. Schneider in the herbarium at Kew, the

tree from the Khasia Hills treated as a variety, khasiana,

of this species and characterised by the possession of very

membranous leaves, is better referred to the genus

Micromeles. .

According to Loudon this species was first introduced

into European collections in 1820; the tree from which the

plate now given has been prepared was purchased for the

June, 1909.

Kew collection from Messrs. Fisher, Son & Sibray of

the Handsworth Nurseries, Sheffield, in January, 1904,

under the name of Pyrus Aria himalaica. As a garden-

tree it is, in some respects, the finest of all the Whitebeams

in cultivation, especially in regard to the size of its foliage

and flowers. The fruits, although large, are not so brightly

coloured as in various forms of P. Aria itself. This species

is somewhat uncertain in its behaviour under cultivation.

After growing quite well for a number of years it will,

without any ostensible cause, and sometimes in the middle

of the active growing season, suddenly droop and soon

afterwards die. To this unfortunate circumstance is probably

due the fact that although the species came into cultivation

in England nearly eighty years ago, there are few, if any,

fully grown trees in this country.

Description.— Tree, of medium size under cultivation,

sometimes of large dimensions in the wild state; innovations

white-woolly, branches soon becoming glabrous, purplish-

brown and _ lenticelled; buds ovoid, subacute, glabrous.

Leaves elliptic, rounded or shortly cuneate at the base, —

shortly acuminate or subacute or obtuse at the apex,

irregularly simply or double toothed and sometimes slightly

lobulate, 5-8 in. long, 3~4 in. wide, firm when full grown,

at first loosely white-pubescent but soon glabrous above,

Prunus japonica is nearly allied to P. humilis, Bunge,

figured in this work at plate 7335, but is readily distinguished

by the glabrous branches, larger leaves and entire petals.

More familiar in its double-flowered form, which has long

been one of the most popular of hardy shrubs, especially for

forcing into early flower for greenhouse decoration, the

species in its natural condition, here figured, is nevertheless

very pretty, and has, in its bright red cherries, an attraction

which its more showy variety does not possess. The double-

flowered form, figured at plate 2176 of this work under the

name Amygdalus pumila, is said by Bretschneider to have

been in cultivation in the Jardin des Piantes at the end of

the eighteenth century, though, according to Nicholson, it

Jung, 1909,

was not introduced to English gardens till 1869. At first

it was imagined that this double-flowered cherry was a form

of P. humilis. This impression was dispelled when the

typical variety here figured was introduced to western

horticulture. According to Bretschneider it first became

known in British gardens in 1835, when it was introduced

from China by a son of Mr. John Reeves. It was not

however obtained for the Kew collection until November,

1902, when the plant from which the present plate has

been prepared was presented by Messrs. Veitch from their

Coombe Wood nursery. This plant is now about 3 ft.

high, and thrives in a sunny border in loamy soil. It has

produced fruit in great abundance during the last three

years, all the younger parts of the bush being plentifully

furnished with its bright cherries, which are extremely acid

and astringent. The plant can be propagated by seeds,

cuttings and layers, but of the three methods the last is

found to be the most satisfactory for obtaining good plants

quickly.

Description.—Shrub, the branchlets, branches and

greyish-brown bark glabrous. Leaves ovate-lanceolate or

lanceolate, acuminate or acute, with rounded or cuneate

base, 2-23 in. long, 1-1} in. wide, the margins doubly ©

Cornus macrophylla is the largest of all the Cornels that

are hardy in the average climate of Great Britain. It is

represented in the Kew Arboretum by several young trees,

the largest of which, however, is not more than 10 ft. high.

June, 1909,

Veitch has figured a specimen, growing at Coombe Wood,

which is 17 ft. high by 12 ft. through. Asarule it forms

a bushy tree branching from the base ; according to Veitch

it flowers very freely in alternate seasons. In the wild

state C. macrophylla has an unusually wide range from the |

North-West Himalaya eastward to China and Japan, and

varies very little except in the size and shape of its leaves

throughout this area. Though introduced into English

collections as long ago as 1827, it is by no means frequently

met with, and while in this country—owing to the fact, per-

haps, that authentic specimens of Wallich’s C. macrophylla

have been readily available for examination, and that these

all undoubtedly belong to the species now figured—there has

been no confusion with regard to the name it should bear,

_ Matters have been otherwise in continental and American

collections. Mr. Hemsley, who has carefully disentangled

the confusion that has found its way into dendrological

literature, points out that the cause of this confusion is due

to the existence in collections of two species of Cornus, one

with alternate and one with opposite leaves. That with

opposite leaves, as a reference to the original specimens at

once shows, is Wallich’s C. macrophylla. This opposite-

leaved species was, however, a quarter of a century after

the publication of the original description, again described

by Meyer as C. brachypoda. On the Continent and in

America Meyer’s name has been adopted for the opposite-

leaved species, and Wallich’s name has been erroneously _

applied to that which has the leaves and branches alternate.

In British collections the identity of the opposite-leaved

species has never been in doubt, but by a converse error

the name C. brachypoda has been applied to that with

alternate leaves and branches. Koehne and Rehder indeed

would treat the Japanese form of the species now figured,

on which C. brachypoda, C. A. Mey., is based, as distinct

from the Himalayan form, but owing to the erroneous

impression that the plant which Wallich described has

alternate leaves, they employ for what is undoubtedly

C. macrophylla, Wall., a new name, C. corynostylis, Koehne.

As a matter of fact, it is the species with alternate leaves

and branches, grown in English collections under the

erroneous name C. brachypoda and in the collections of

other countries under the equally erroneous name C. macro-

phylla, that stands in need of a distinctive name. For this

alternate-leaved Cornel Mr, Hemsley proposes the name

C’. controversa.

C. macrophylla thrives best in good loamy soil in a sunny

position, and the only special treatment called for is the

pruning away of the lower branches, so that a clean trunk

5 or 6 ft. high may form. If this be done, it makes a

very handsome small tree of distinct and striking aspect.

The most suitable use for it in the garden, perhaps, is as an

isolated specimen on the lawn.

Descriprion.— Tree, usually 15-30, sometimes up to 50 ft.

high, all parts except the flowers glabrous or obscurely

puberulous ; flowering branches rather slender, dull reddish.

Leaves opposite, usually ovate, sometimes lanceolate or

elliptic, generally 4—6 in. long, but at times longer or shorter,

tapering to a caudate-acuminate apex, base rounded or

cuneate sometimes unequal, papery, glabrous or soon

glabrescent above, beneath pale or glaucous usually more

or less beset with small closely adpressed centrally attached

hairs ; main-nerves conspicuous, usually 5-9 on each side,

oceasionally on leaves of the same branch 4 or 8; petiole

slender, 14-2 in. long. /owers 4-merous, yellowish-white,

4—} in. across, in compound stipitate terminal and lateral

cymes 23-5 in. across, with glabrous or glabrescent branches

and without bracts or bracteoles; pedicels shorter than the

flowers. Calyx 1-14 lin. long, densely covered with silvery

hairs ; tube distinctly ribbed, teeth minute. Petals valvate,

lanceolate, somewhat obtuse, spreading or recurved, hairy

without. Stamens shorter than the petals; anthers dorsi-

fixed. Drupes globose, 24-34 lin. across, the tip not

hollowed.

NOTICE OF RE-ISSUE.

Some portions of the above work being out of print, and complete sets

very difficult to obtain, the Publishers have determined to reprint so

much as will enable them to complete a few copies as they may be

subscribed for ; and to meet the convenience of Subscribers, to whom

the outlay at one time of so large a sum as a complete set now costs

is an impediment to its purchase, they will commence a re-issue of

two Volumes Monthly, thus spreading the cost over a period of

two and a half years. The price of the volumes will be 42s. each as

heretofore, but to Subscribers for the entire series 36s. each, or a

complete set of the 60 vols. will be supplied for £100 cash. Subscribers

may commence at any time.

The BoranicAL MaGAzINE, commenced in 1787, and continued

with uninterrupted regularity to the present time, forms the most

extensive and authentic repertory of Plant History and Portraiture

extant. The Tuirp Seriss, by far the most valuable, comprising all

the important additions of the last sixty years, contains nearly 4000

Coloured Plates, with Descriptions, structural and historical, by Sir

William and Sir Joseph Hooker.

A set complete from the commencement in 1787, including the First,

Second, and Third Series, to the end of 1904, 130 vols., may be had,

price £136. ,

N.B.—A Fourth Series commenced in January, 1905, and is edited

Coelogyne venusta is a very distinct species which

Mr. Rolfe would refer to the section Tomentosae, but

which the late Dr. Pfitzer was inclined, on account of the

remarkable lip, to treat as the type of a separate section,

the Venustae. A smaller plant than most of its nearer

allies, it is distinguished from all of them by the relatively

greater size of the anterior as compared with the lateral

lobes of the lip. For its introduction to this country, from

8.W. China, horticulture is indebted to Messrs. Sander of

St. Albans; a plant supplied by them flowered in 1904 at

Glasnevin, whence came the material on which the original

account of the species was based. It thrives well under the

conditions suited to the Himalayan Ooelogynes,

Juty, 1909.

Aloe rubrolutea appears to. have a wide range in the

Kalahari desert and in German South-west Africa where it

has been collected by several travellers. It is said to be

plentiful in the neighbourhood of the Etasa Lake and on

the mountains near Klein Windhoek. Dr. Schinz gives

the stems as from 34-5 ft. in height, but Mr. Dinter reports

them as reaching 8 ft., and judging from photographs even

taller individuals are not infrequent; indeed in the wild

state it appears to come nearest in size to A. dichotoma, It

has been repeatedly introduced to Europe by Dinter, and

seems to have also been collected by Dr. Baum during his

Kunene-Zambesi expedition. The plant from which the figure

now given was made was sent alive as a young specimen

by Dinter from Windhoek, in 1904, to the late Sir T.

JuxLy, 1909.

Hanbury in whose garden at La Mortola it flowered for the

first time in November, 1907 ; this is possibly the first record

of the species having flowered in Europe. The same plant -

- flowered again in November, 1908, and afforded the material

- utilised for our plate. Seedlings of this species are now

__ probably frequent in gardens. They look rather unlike the

“adult plant as their leaves are densely covered with round

white spots, which gradually become less frequent and

ultimately disappear as the plants grow larger. Even at

La Mortola the species is not quite hardy ; though rather

quick-growing and otherwise presenting no cultural difficulty,

it is sensitive to cold. Like many other Aloes, A. rubrolutea

18 @ very ornamental green-house plant, and like other

tropical species may perhaps do well in a temperate house ;

it should if possible be given a place in a border with rich

but gravelly soil. Strong and old specimens will certainly

prove handsome and valuable objects in a collection.

Drscriprion.—Stem unbranched, stout, 8 ft. or more in _

height, covered with old leaves; in the young plant here —

figured only 6 in. high, 24 in. thick. Leaves about 20 in a

dense rosette, lanceolate-ensiform, spreading and flat at the

base, slightly wider at the middle, thence acuminate and

channelled to the acute tip, thick and fleshy, glaucous-green,

the margins beset with brown deltoid and somewhat hooked

spines, about 2 ft. long, 44 in. wide; in the La Mortola

specimen 17 in. long. Panicle much-branched, branches

somewhat spreading, naked below but with a few empty

bracts under the raceme. Racemes about 1 ft. long, cylindric,

slender, with many rather lax, drooping flowers; bracts

whitish, lanceolate, acute, 3-8-nerved, 4-3 in. long, at first

imbricate, at length more or less reflexed; pedicels 3-5 lin.

long, much elongated in fruit. Perianth straight, cylindric,

somewhat widened near the top, bright red, 14 in. long;

The plant here figured is one of the most distinct and

attractive of the many Rubi recently brought into cultiva-

tion. The Kew example was presented to the national

collection by Professor Sargent of the Arnold Arboretum

in 1902, and has since its introduction been cultivated

under the name Ff. Millspaughii proposed by Dr. Britton.

Professor Bailey has, however, definitely identified it with

the true #. canadensis of Linnaeus, and this name is here

accordingly adopted. Popularly known as the “ Thornless

Blackberry,” &. canadensis appears to extend in a wild

state from Eastern Canada, through the highlands of New

England, New York and Michigan to the mountains of

North Carolina. In habit our plant resembles the common

Raspberry, forming sturdy, erect stems 6 or 7 ft. high? The

Jury, 1909.

flowers are produced in June in large, racemose inflorescences

which spring from each node on the upper part of the

previous year’s growth. The plant thrives well in an

ordinary border of loamy soil, and the only special attention

it requires is the cutting away of the old stems after

- fruiting.

Description.— Shrub, erect or suberect, stems unarmed

or occasionally slightly thorny, roundish, rather thick,

brown ; new shoots finely puberulous; internodes 2-3 in.

long. Leaves 3-5-foliolate; petioles glabrous, 14-3 in.

The name Ringo first appeared in Siebold’s “ Catalogue

raisonné” of 1856, which records a considerable number of

new introductions from Japan. Though we employ here

for this Japanese Crab the name that accords with the

treatment of the Pomeae adopted in the “Genera Plantarum,”

it is to be noted that Siebold in the first instance referred

the Ringo to Malus, and there is much to be said in favour

of treating the group of forms to which this term is

applied as a distinct genus; this treatment is accorded to

Malus in the recent authoritative works of Koehne and

Schneider. The latter dendrologist records the examination

by him of specimens from a tree in the Jardin Plantieéres

the introduction of which is said to be traceable to Siebold,

and the conclusion to which he has been led is that the

Ringo represents a cross between P. spectabilis and some

form of the common apple.

Juny, 1909.

The tree from which the present plate was prepared

has Jong been in cultivation at Kew and is now about 14 ft. -

high, and no form of Pyrus in the collection is better worth

cultivating for the beauty of its fruits than this. These

hang from the branches in great abundance, and when they __

have acquired the bright yellow colour characteristic of the

ripe condition, there are few of our smaller trees that make

so charming an autumn picture. Among the specimens in

the Kew herbarium there is one from a tree grown in the

Arboretum which has the general appearance of the Ringo,

but has leaves that, when mature, become glabrous beneath.

Koehne has described, as P. Ringo fastigiata bifera, another

variety characterised by a pyramidal habit, and, as regards a

form with more glabrous leaves than usual, suggests that

the peculiarity may be due to the presence of a strain of

P. prunifolia, He describes also a hybrid between P. Ringo

and P. spectabilis.

The Ringo requires no special soil or treatment, except

that like other allied species it is subject to the attacks of —

“ American Blight” (Schizoneura lanigera). This, however.

is easily kept down by an occasional spraying with an

emulsion of paraffin and soap. Bis

A study of the careful revision by Dr. Fedde of the group

of species to which the name Mahonia is popularly applied

leaves little room for doubt that, from the scientific stand-

point also, this group is more satisfactorily considered

generically distinct from Berberis proper. The distinctions,

as pointed out by Fedde, are that in Berberis the leaves are

simple while the inflorescence springs from the axil of a leaf-

thorn, whereas in Mahonaa the leaves are compound and the

inflorescence arises from the axil of a winter bud-scale.

M. arguta, the species now dealt with, is most nearly allied

to M. paniculata, but is readily distinguished by the narrower,

entire or few-toothed leaflets which are more prominently

veined on both surfaces, and by the smaller petals.

JpLy, 1909.

The plant from which our figure has been prepared had

been in cultivation in a warm-house at Glasnevin for over

thirty years, and had developed into a tall lanky shrub with

terminal leaf-tufts. Mr. Moore, to whom we are indebted

for the material used, and for this information, has been

unable to trace the history of the plant or to find any clue

to its native country, but from the fact that the more nearly |

allied forms are all natives of Central America, where they

occur on the slopes of voleanic mountains in Guatemala and

Costa Rica at altitudes of from 8,000 to 12,000 ft., it is possible

that MM. arguta may also have originally been obtained from

this region. In 1906 the plant was removed to a cool airy

house, and during the summer was placed out of doors,

being again brought under glass in October. It responded _

to the new treatment by flowering in May, 1907, and again

in 1908 as a result of a repetition of the treatment of

wintering in a cool airy house and plunging in the open —

air during summer. Potted in good heavy loam y

little sand the plant is now healthy in apy a

making vigorous growth. It is, indeed,

milder parts of Ireland and in the south-we

the species may prove to be hardy. |

Caralluma Nebrownii is one of the largest-flowered species

in the genus, and is most nearly related to C. lateritia,

N. E. Br., a native of the northern Kalahari desert, from

which the plant now figured differs in having much longer

_ pedicels, a more rugose corolla of a blackish-crimson colour

~ flecked with very small yellowish spots on the disk and at the

base of the lobes instead of a uniform brick red ; the corona

in the present plant is also larger than that of C. lateritia.

C. Nebrownii is allied also to C. huillensis, Hiern, an

Angolan species, and to C. lutea, N. E. Br., a species from

South Africa. In both of these plants the pedicels are

shorter than in the subject of our plate; C. huillensis has

moreover pubescent stems, while in C. lutea the flowers are

yellow and the stems have a different facies,

Avaust, 1909.

The species now described was discovered by Mr. Dinter

near Barmen in German South-west Africa (Dinter, n. 1502).

Living plants sent by him to the late Sir Thomas Hanbury

at La Mortola flowered there in July, 1907, and again in

November, 1908, when the specimens from which our

drawing was prepared were forwarded to Kew. The plant

calls for very dry treatment, more especially in winter, when

little or no water should be given to it.

Drscription.— Herb; stems succulent, leafless, somewhat

clustered, erect, 4-angled, the angles coarsely toothed, usually

3-6, occasionally 10 in. in height, 4-lj in. thick not in-

This remarkable Colombian orchid flowered in the collec-

tion of the Rev. J. C. B. Fletcher, Mundham Vicarage,

Chichester, in November, 1908, shortly after having been

obtained from Messrs. Hugh Low & Co. It appeared

unexpectedly among some species of Mormodes collected at

Simacota, near the River Opon, Colombia, by Mr. J.

Birchenali. It is interesting on account of the great

diversity between the sexes, which, as in the present

instance, are occasionally borne together upon the same

pseudobulb, the females being many times larger and

heavier than the males, and different not only in the shape

of the sexual organs, but also in the shape, texture and

colour of the perianth. The column of the male is long

and slender, bearing the anther at the summit, while in

Aveust, 1909,

the female it is very short and stout, with a pair of

triangular fleshy wings at the sides of the stigma. The

lip in the female is a large, ovate, fleshy body, but in

the male it is reduced to a small circular disk, surrounded by

a number of clavate marginal appendages. The sepals and

petals are membranous in the males, and very fleshy in the

females; the differences in size and colour are well shown

in the figure. These, differences do not extend equally to

every species in the genus, nor were they known to be

differences of sex until comparatively recently, as may be

seen by the account given at plate 4054 of this work. The

history of the genus has been reviewed by Mr. Rolfe ina

recent paper in the Kew Bulletin for 1909 (pp. 268-277).

Descriprion.—Herb, with erect terete pseudobulbs about

6 in. high, clothed with membranous scales. Leaves oblong-

lanceolate, acute or acuminate, recurved, somewhat undulate,

about 5-7 in. long, 1-1} in. wide. Flowers monoecious.

Male racemes pendulous, many: and dense-flowered, about

14 in. long; bracts lanceolate, acuminate, membranous,

about 4 in. long; pedicels slender, about 2 in. long. Sepals

and petals of male flowers membranous, oblong-lanceolate,

The subject of our plate appears to be a somewhat

polymorphic species which is rather widely spread in

Tropical Africa from British East Africa to the Zambesi.

The genus Erlangea, to which Mr. Moore has referred it,

differs from the genus Vernonia only in respect of its

reduced achenes, and in having the pappus reduced to a few

short, very caducous hairs. Till a few years ago it was

deemed a monotypic group; now it is believed to consist of

at least thirty-two species, several of which, however, had

formerly been included in Vernonia. With the exception of a

single species from New Guinea which has been referred to

this genus all the Erlangeas are African. The nearest

ally of EH. tomentosa is EL. fusca, S. Moore, from which, as

Mr. Hutchinson points out, it is readily distinguished by

the bright green leaves and the scariously edged involucral

bracts. :

Avevst, 1909.

The plant from which the figure now given has been

prepared was presented to Kew in April, 1907, by Mr. R.

Diespecker, Adstock House, Winslow, who had raised it

from seed received from British East Africa. It has formed

a shrub, in habit much resembling some of the Kupatoriums,

attaining a height of 5 ft.; it flowers freely and _con-

tinuously during winter and spring. It admits of easy

cultivation in a green-house, and requires the treatment

most suitable for the winter-flowering species of Hupatorium.

Descriprion.—Shrub, attaining a height of 5 ft., branches

furrowed and sparingly villous, branchlets densely villous-

tomentose. Leaves oblong or oblong-lanceolate, base

cuneate or slightly rounded, apex subacute, 2-5 in. long,

$_13 in, wide, doubly serrate, membranous, pubescent above,

Spiraea Henryi was discovered by Mr. A. Henry in

Hupeh, near Ichang, in 1885, and later in Szechuen, but

for its introduction to cultivation our gardens are indebted

to Messrs. J. Veitch & Sons of Chelsea, whose collector,

Mr. E. H. Wilson, found it in 1900, also in Hupeh. It

belongs to the section Chamaedryon (Ser. in DC. Prodr. ii.

_p. 542), and, like many of its allies, is a very charming

acquisition. Among older species it is most closely related

to S. canescens, D. Don, and its flowers, as in that species,

are arranged in rounded corymbs on the upper side of long

arching branches; its nearest ally is, however, S. Wilsoni,

Duthie (Hort. Veitch. p. 379), which is also described as

having the peduncles and pedicels covered with silky hairs,

but is in reality almost glabrous. In mid-June, 1908, it

was one of the most beautiful deciduous shrubs in flower

at Kew. Mr. Henry observes that its leaves are used by

the poorer natives as a substitute for tea.

Avavusr, 1909.

' The plant from which our figure was taken was obtained

from Messrs. Veitch in 1905. Since then it has grown

excellently in a border of loamy soil, and is now a bush

7 ft. high and 10 ft. in diameter. Having passed through

the winter of 1908-9 without any injury, the species may

be regarded as absolutely hardy. It can be increased by

means of cuttings made from half-ripened wood. From the

cultivator’s point of view, shrubby Spiraeas may be divided

into two great groups, viz. those that blossom on the shoots

of the current year, and those that do so on the shoots of

the previous one. S$. Henryi belongs to the latter. What-

ever pruning, therefore, may be necessary, should be done

us soon as the flowers are past, and it should be a process of

thinning out rather than a general shortening back of the

branches, the leading idea being to produce long, uncrowded

branches, and, by preserving a loose, open habit, thereby to

display to the best advantage the numerous white corymbs

with which they will in due time be garnished.

Descriprion.— Shrub, of lax, spreading habit, 7 to 8 ft.,

or perhaps more, high; branches sparsely pilose the first

season, glabrous or nearly so the second. Leaves on the —

barren shoots 24-34 in, long, oblanceolate, glabrous or

slightly pilose above, tomentose beneath, coarsely dentate

near the apex; those of the flowering shoots smaller, #-14

in. long, obovate or oblong, usually with three to seven

teeth at the apex, but occasionally entire. Flowers 4 in. in

diameter, produced in compound corymbs 2 in. across, which

are terminal on short twigs springing from the branches of

the previous year ; peduncles and pedicels pilose. Petals

white, orbicular. Calyx with five triangular lobes. Ovary

pilose, two-ovuled, Fruit in corymbs; carpels 5, $ in, long

when mature, membranaceous, dehiscing ventrally.

The subject of our plate is a member of the Littaea section

of Agave and is allied to A. geminiflora, Seannag. (Littaea

geminiflora, Tagliabue), the species on which the genus

Littaea was originally based. The plant now figured was

acquired for Kew from the collection of Mr. T. H. Kellock

in 1903 under the name A. TJaylori. That it is not the

true A. Taylori, Hort. Williams (Gard. Chron. 1874, vol. i.

p. 418) —which is stated (Gard. Chron. 1877, vol. viii. p. 621,

Aveust, 1909.

fig. 125, and Baker, Handb. Amaryllid. p. 186) to be a

garden hybrid whereof A. geminiflora is one parent and

A, jilamentosa is probably the other—was at once recognised,

and our plant was therefore tentatively treated as possibly a

variant of A. geminiflora until it flowered in the Mexican

House at Kew in November, 1908. Mr. C. H. Wright, by

whom the plant was then examined, found it to differ from

A. geminiflora in the colour of its flowers as well as in its

leaves, which are smooth and subulate in place of being

narrowly loriform and striate. It appeared to Mr. Wright

that its nearest ally is A. angustissima, Engelm., first

named, but not then fully characterised (Trans. St.

Louis Acad. Sc. vol. iii. p. 306) in 1876, but that it is

specifically distinct from Engelmann’s plant. A comparison

with specimens to which Dr. Trelease has attached the name

A. angustissima, and a study of the figure and description

of that species supplied by Dr. J. N. Rose (Garden and

Forest, vol. iii. pp. 5 and 6) in 1893 have satisfied Mr.

Drummond that Mr. Wright’s conclusions are justified.

Though allied to A. angustissima, A. Wrightii differs from

that plant by the shorter, less constricted perianth-tube, by

the yellow in place of purple anthers, by the less flattened

leaf-blade which has the upper face channelled inside either

margin, by the broader leaf-neck and by the much wider

and much more abruptly shouldered leaf-base. As regards

floral structure, Mr. Drummond points out that A. Wrightii

approaches most closely to the plant figured as A. gemini-

flora (Bot. Reg. t. 1145) in 1828; from that plant

A. Wrightii is readily distinguished by its much wider and

more gibbous leat-base; but, except in having white in

place of coloured filaments, hardly differs as regards flowers.

The plant thus depicted by Lindley is not, however, A.

geminiflora, Scannag., and to distinguish it Mr. Drummond

suggests the employment of the name A. Knightiana. It

may be added that this species has remained not only

unnamed, but undescribed, for the description associated

with it in the Botanical Register has not been based on,

and does not apply to, the plant there figured, but has been

taken, unmodified, from the reprint in the second volume of

the Journal of Science (1817) of the original account of

Littaea geminiflora published by Tagliabue (Bibl. Ital. vol. 1.

p- 9) in 1816. :

Description.— Trunk short, hidden by the rather close

rosette. Leaves between fleshy and leathery, somewhat

flexible, more or less erect when young, at length drooping,

16-18 in. long, tapering evenly to a fine point tipped with

a short stoutish spine, from a gibbous base 1% in. wide at

its origin, 11 in. wide at the shoulder whence it is gradually

rounded to the unconstricted neck, nearly 1 in. thick ;

lower surface uniformly triangular-convex, bluntly keeled

with a few irregular blunt creases; upper surface for

about 44 in. above the neck depressed-convex with a blunt

‘somewhat obliquely placed keel, above shallowly channelled

with a rounded ultimately obsolete central ridge; smooth

and dull apple-green flecked with minute white spots on both

surfaces; margins sharp without teeth or prickles, but with

a fine horny border ultimately shredding into hair-like

whitish filaments. Scape about 10 ft. high, peduncular

portion about 3 ft. long, with involute acicular more or less

scarious bracts about 23 in. long gradually diminishing

from the base upwards. Flowers in pairs arranged in a

rather dense spike about 7 ft. long, on very short barrel-

shaped pedicels, bracteolate. Perianth lobes about 8 lin.

long, 3 lin. wide, revolute, dark green with creamy-white

borders; tube 5-6 lin. long, little constricted. Stamens

subulate ; filaments almost colourless, nearly 24 in. long;

anthers bright yellow, their cells at length free at the base.

Ovary cylindric, 5-6 lin. long; style 24 in. long.

Aphelandra tetragona, as here figured, is a native of

Guiana and Venezuela, which has long been in cultivation

at Kew. It is, without doubt, the species described by

Vahl in 1794 as Justicia tetragona, from specimens collected

by Dr. Rohr near Cayenne, and is exactly the plant figured

by Jacquin in 1798 as Justicia cristata, though it is some-

what uncertain as to whether it be the plant figured as

Aphelandra cristata at t. 1578 of this work. The plant

SEPTEMBER, 1909.

represented on that plate agrees precisely with specimens

from Trinidad, Tobago and British Guiana, all of which

have bracts that are only half the size of those in the plant

now depicted, have quite short flowering spikes and have

uniformly smaller leaves.

At Kew A. tetragona is grown in a tropical house. It

flowers at various seasons according to the age of the plant

and the treatment it is given; the plant from which the

present figure was made flowered in September, 1908, but

an even finer example came into flower in May, 1909, the

head of flowers, borne on a single stem nearly 4 ft. high,

consisting of 13 spikes, each from 4-7 in. long. The

plant in question was two years old, and had been raised

from a cutting ; older plants do not flower so well. A rich

loamy soil and an abundant supply of water at the roots,

with a tropical temperature, are the most suitable conditions.

Descriprion.—Shrubby ; branches round, hollow, smooth,

up to ¥ in. thick. Leaves ovate-lanceolate to widely ovate-

elliptic, abruptly narrowed to a cuneate or decurrent base,

apex shortly or considerably acuminate, margin faintly

undulate-crenate, 8-10 in. long, 4-6 in. wide, papery,

glabrous above, whitish pubescent in bud, but soon becomes

glabrous beneath ; petiole 13-2 in. long. Spikes usually

3—5-nate, occasionally solitary, rarely 9—13-nate at the ends

of the branches, the terminal 6-7 in. long, 2 in. thick

without the corollas, very dense; bracts ovate, acute or

subacuminate, 5-6 lin. long, greenish-brown, firm, woolly

white at the base and villous along the margins, else-

where glabrous, markedly striate below, faintly glandular ;

bracteoles lanceolate, white villous, 5 lin. long. Sepals

scarious, lanceolate, acute, 4 in. long, slightly villous at the

tips. Corolla brilliant pink, puberulous; tube narrowed

above the base, thence gradually widening to the limb and

there 3-4 lin. wide; upper lip $ in. long, bifid, lobes acute,

3 lin. long; lower lip gradually narrowed from a wide

limb, $-1 in. long, 4—5 lin. wide, the lateral lobes reduced

to a margin | lin. wide, ending upwards in a small tooth.

Anthers 3-4 lin. long, finely pilose on the back.

Megaclinium purpureorachis, much the largest species of

this genus yet known, was first met with by Mr. Gentil on

_ the Upper Lomami, a tributary of the Congo, in January,

1903, and was described and figured by Professor de

Wildeman from fruiting specimens. The flowers remained

unknown until September, 1908, when the plant from

which our plate has been prepared came into flower at

the Royal Botanic Garden, Glasnevin, whence material

was supplied by Mr. Moore. A plant was subsequently

exhibited by Sir Trevor Lawrence, Bart., at a meeting of

the Royal Horticultural Society in April, 1909; in this

instance under the name M. Bufo. It is, however, very

different from the plant thus designated, which was

SepreMbeER, 1909.

described by Lindley from the inflorescence only, and

which has recently reappeared in cultivation. The

nearest ally of the plant now described is MZ. maximum,

Lindl., a species figured at t. 5936 of this work under the

name MM. marmoratum, Lindl. The present species is

readily distinguished from M. maximum by its considerably

larger size and its very hairy brown flowers. Mr. Moore

informs us that the plant from which our material was

derived was obtained from Messrs. Sander and Sons in 1905 ;

it thrives vigorously in an intermediate house, with a

minimum night temperature of 55° F.; it requires light,

and has to be grown close to the glass. The strong stiff

_ rhizome does not bend readily ; it is therefore advisable to

grow the plant in fairly shallow pans rather than pots.

A few chopped oak-leaves added to the compost appear to

encourage growth.

Descriprion.—Herb, epiphytic, rhizome stout, woody ;

pseudobulbs elliptic-oblong, somewhat flattened, 24-3 in.

long, 1-14 in. wide, 2-foliate, the base clothed with

membranous striate ovate conduplicate sheaths. Leaves

subsessile, oblong or elliptic-oblong, rather obtuse,

coriaceous, 8-12 in. long, 13-2 in. wide, finely dark-

punctate beneath. Scapes lateral, stout, suberect, 12-14

in. long, clothed at the base with numerous ochreate

sheaths; rachis broad, flattened, undulate and slightly

spirally twisted, freely dotted with purple spots and

scabridly puberulous, 6-8 in. long, 14-14 in. wide, many-

flowered; bracts ovate or ovate-oblong, apiculate or

acuminate, recurved at the tips, their bases transversely

decurrent on both sides, 4—5 lin. long; pedicels about 2 lin.

long. Flowers brown, scabridly velvety outside; posterior

sepal ovate-oblong, subacute, concave, incurved with a

reflexed tip, about 4 lin. long; lateral sepals oblique,

triangular-ovate, acuminate, with their tips falcate, about

4 lin. long. Petals linear-falcate, acuminate, 23-3 lin.

long; lip orbicular-ovate, recurved, obtuse, flattened, 2 lin.

long. Column broad, 2 lin. long; teeth distinct, 2-fid at

the tip. Capsule oblong, about | in. long.

The genus Exostemma includes nearly forty described

species, whereof twenty are known to occur in the West

Indies, chiefly in Cuba. £. subcordatum, the species now

figured is, however, a native of San Domingo, and is met

with in the more mountainous parts of that island. The

plant from which our plate has been prepared was presented

to Kew in 1903 by Professor Hansen, Director of the

Botanic Gardens, Giessen, under the name E, floribundum, to

which species it is indeed most nearly allied, but from which

it chiefly differs, as Mr. Hutchinson points out, in baving

longer calyx-segments; from this and all other known

species of the genus it is, moreover, readily distinguished

by its subcordate leaves. Under cultivation the Kew plant

has formed a loosely-growing shrub about 3 ft. high;

it flowers freely in autumn, the flowers being pure white

SepTemBeER, 1909.

and very fragrant. It thrives well in a tropical house

under the treatment suitable for Ixoras. Two other

members of the genus are in cultivation; these are

E. caribaeum, Roem. and Schult., and £. longiflorum, Roem.

and Schult.; the latter has been figured at t. 4186 of this

work.

according to Jacquemont attaining in the wild state a height

of 10 ft.; branches terete, when young shortly puberulous,

at length becoming glabrous; bark grey. Leaves ovate or

ovate-lanceolate, more or less subcordate at the base, acumi-

nate at the apex, margin revolute, 2-3 in. long, 1-1} in.

The plant from which the figure of Huphorbia Ledienii

now given has been prepared is one that has been. in

cultivation in the succulent house at Kew since 1868, when

it was presented by the Jate Admiral Sir A. Milne, along

with various other South African succulent and bulbous

plants received by him from Mr. Morrison. Another

example of the species, now in the Kew collection, was

acquired by purchase from Mr. A. Bennecke in 1893. The

same species is said, however, to have been in the collection

of Mr. W. W. Saunders at Reigate in 1866, and according to

Mr. Berger, who first vindicated its right to specific rank in

1907, EL. Ledienii is not uncommon in Continental gardens.

Its nearest ally, among the species at present in cultivation,

appears to be LE. coerulescens, Haw., from which, as Mr.

Brown points out, it differs by its more numerous and less

Sepremser, 1909.

sinuous angles, its more distant and less marked constric-

tions, and its shorter spines. Like the other species of

Euphorbia which share its habit, it grows very slowly, but

it flowers freely every year in late autumn under ordinary

tropical conditions, :

_Descriprion.—Shrub, succulent, branching, soon leafless,

3 ft. or more high, quite glabrous. Branches sharply 5-7-

angled, 14-3 in. thick, slightly narrowed at intervals of

from 3-8 in.; angles not or only slightly and at intervals

hardened along the edge; grooves between the angles

rounded concave. Leaves minute and scale-like, } lin. long, °

1 lin. wide, wide rounded, soon disappearing. Spines in

pairs, divergent, 2—4 lin. long, brown at first but becoming

ash-grey, the pairs 4-3 in. apart. Cymes bearing each

three involucres, usually several in each axil, clustered, their

stalks about 1 lin. long; bracts scale-like, 1-1 lin. long,

wide rounded or oblong and slightly truncate, minutely

denticulate at the tip. Involucres 14-2 lin. long, obconic,

truncate, glabrous, yellow; central male; lateral bisexual ;

glands transversely oblong, entire, about } lin. long, 3 lin.

wide ; lobes quadrate, fimbriately toothed Ovary glabrous;

The genus Peliosanthes includes about a dozen species, all

of which are natives of South-eastern Asia. Three of these

have already been figured in this work; /. Teta, Andr., at

t. 1302, P. humilis, Andr., at t. 1532, and P. albida, Baker,

at t. 7110. The first of these, which has its flowers fascicled

in the axils of the bracts, has an unusually wide range ; it

extends from the Eastern Himalaya throughout Western

Indo-China to the Malayan Peninsula; throughout this area

is subject to remarkably little variation. Among those

species in which the flowers are solitary in the axils of the

bracts, that compose the bulk of the genus, the only one

which is credited with an equally wide range is P. violacea,

Wall. In the case of this species, however, Mr. Baker

recognises, in addition to the typical form, which has a deep

violet perianth and is found in the Eastern Himalaya and

in the mountains of Assam to the east of the Brahmaputra

river, also extending to Lower Burma, three distinct

varieties. Two of these, var. minor, with small green

flowers and leaves that are only 5-7-nerved, and var.

SepremBeEr, 1909,

princeps, a raore robust plant than typical P. violacea, also

with greenish flowers, are suspected by Mr. Ridley to be

distinct from P. violacea. The third variety, recognised by

Mr. Baker as var. Clarkei, which extends from the Khasia

Hills in Assam southwards to the Malay Peninsula, and

which is here figured, is believed by Mr. Ridley (Materials

for a Flora of the Malayan Peninsula, pars 11. p. 89) to be

the plant intended by Mr. Baker as P. violacea proper.

This is not, however, the case, for while it is possible that

Dr. Wallich did not consider these two forms, which hardly

differ in morphological characters, to be distinct, the name

P. violacea is restricted by Mr. Baker to the form with

deep violet perianth; the form with dark-purple perianth

here figured is kept apart by Mr. Baker as var. Clarkei.

The plant now depicted was presented to Kew by Mr.

Ridley in 1904; it had been obtained by him in Perak.

It flowers annually in a tropical house, usually in April,

and is one of the most attractive of the species of Pelio-

santhes cultivated at Kew. :

Descriprion.—Herb, rootstock short. Leaves oblong-

lanceolate, acuminate, reaching 1| ft. in length, 24 in. wide,

quite glabrous, margins caret ginous, slightly crenulate ;

main nerves about 20; transverse veins numerous, con-

spicuous; petiole 5-12 in. long; basilar-sheaths membra-

nous, brown. acemes about 6 in. long; flowers solitary,

dark purple; bracts oblong, acuminate, longer than the

pedicels. Perianth rather wide campanulate, 5 lin. across;

tube 6-channelled; lobes oblong, rounded at the tips.

Anthers ovate, their bases 2-lobed. Ovary conoid; style

columnar, 3-sulcate.

The fine species here figured in general character

resembles the well-known and brilliantly coloured Cereus

speciosissimus, to which our plant is indeed very closely

allied. The stems of the two are similar in appearance,

though those of C. speciosissimus are mostly 3—4-angled,

whereas in our plant, while the more erect stems are

3—4-angled, those that grow more or less horizontally are

often, at least in part, 5-angled, and the growing shoots do

tt show the dal purplish tinge at the tips which

characterise those of C. speciosissimus. In our plant,

- moreover, the flowers are pure white. C. amecamensis is a

native of Mexico, where it was discovered by Mr. E. Heese

on Iztaccihuatl Mountain, near Amecameca, growing as an

epiphyte in the upper Fir-tree region, at about 7,800 ft.

above the level of the sea. For its cultivation C. ameca-

mensis requires the treatment suitable for Phyllocacti; an

abundance of heat and moisture with ample sunshine in

summer, and dryness near the root in winter. The large

OctopEr, 1909.

white flowers are produced in May or June. For the plant

from which our figure has been made, Kew is indebted to

the generosity of Mr. H. J. Elwes, of Colesborne, who

presented it to the establishment in 1900 as an unnamed

Cactus from Mexico.

Descriprion.—Herb, with succulent stems, branching

from the base; branches elongate, erect procumbent or

pendulous, sharply 3—5-angled, 3-14 in. thick, pale green,

the angles slightly sinuately toothed and with white- or

grey-tomentose swellings. Spines in clusters of 11-15,

slender, needle-like, 4—7 lin. long, at first white, at length

brownish. lowers large, white, 6—7 in. across, widely

campanulately funnel-shaped, the tube above the ovary

very short. Sepals narrow lanceolate, acute. the inner

about 3 in. long, the outer much shorter, pale green.

Petals 2—3-seriate, about 4 in. long, 1 in. wide, lanceolate

or narrowly oblong-lanceolate, obtuse or subacute, pure

white. Stamens numerous; filaments white, anthers pale

yellowish white. Ovary 14 in. long, beset with spines and

scales ; stigmas 6-10, pale yellowish white.

T. A. SPRAGUE.

Cissus adenopodus is a species that does not appear to be

ted ee abe hitherto ecient might

perhaps be placed beside C. Buchanani, Planch. (Monogr.

p- 601) which differs in having 5 leaflets and a very

elandular inflorescence. For the introduction of this plant

Kew is indebted to Mr. M. T. Dawe, who sent it in 1905

from the Mufukamata Forest, Uganda, as a “ species of Vitis

with red decorative foliage.” It has grown very vigorously

in a tropical house, where its long trailing stems, clothed

with red leaves, are very attractive in summer. The leaves,

as in the other species of the section to which it belongs,

are deciduous; the measurements given in the text are

average ones, the largest adult leaves met with reach a

October, 1909,

length of 8 to 9 in, including’ the petiole, and are about

7 in. broad. At Kew the plant flowers in autumn, while

the fruits ripen in the following spring. The absence of

gland-tipped hairs from the inflorescence, apart from those

on the pedicels, is peculiar. Three kinds of hairs are

found on C. adenopodus ; subulate, acute, multiseptate hairs

filled with red cell-sap; linear, gland-tipped hairs; and

bodies which Mr. Sprague terms “ pearl-olands.” These

last are met with on the inflorescence, usually near the base

of the pedicels, on the under surface of young leaves, and

on the outside of the stipules, near the base. These have

been observed in numerous species of Ampelidaceae, and

they seem, at least in certain cases, to serve as “ food-

bodies” for ants.

Drscriprion.—Herb, climbing by means of tendrils.

The tree here figured is a member of the small family

Monimiaceae and belongs to a tribe for which the name

Atherospermeae is sometimes used, The structure of the

flowers and fruits in the genus Laurelia to which our plant

OoroseER, 1909.

belongs is, however, so similar to that met with in Athero-

sperma, Labill., that the late Mr. Baillon was led to think

that the two are congeneric. The bracts met with at the

base of the flowers in Atherosperma, which have been relied

upon as affording a distinctive character, are also present in

Laurelia, though there they are soon caducous and not, as

in Atherosperma, persistent, so that the conclusion formed

by Baillon is probably just.

The subject of our plate is a native of the southern parts

of Chile, where it is known as the Huanhuan tree and is

prized for its timber, though it is neither quite so common

nor quite so valuable as another and better-known species

of the same genus, L. sempervirens, Tul., the Chilian

Laurel. The material from which our figure has been

prepared was communicated to Kew by Mr. F. W. Moore

of Glasnevin from a fine tree in the garden of the late

Mr. Acton of Kilmacurragh, by whom it had been acquired

from Messrs. Rollison of Tooting about 1868; an excellent

figure of a fruiting specimen from the same tree was pub-

lished in the Gardeners’ Chronicle in December, 1904

(vol. xxxvi. p. 401, fig. 172) as LZ. aromatica, Poir. Bertero

had, however, in 1829 pointed out that the species here

dealt with is quite distinct from L. aromatica, and, although

Bertero gave no technical description of the tree, Philippi

subsequently distributed good specimens of the plant under

the name L. serrata, Bertero. In spite of this, however,

it became the practice to cite Bertero’s name as a synonym

of L. sempervirens, and this practice was persistently followed

until in 1894 Castillo and Dey published rough figures of

both species and drew attention to some of their salient

differences, Since 1894 it has been generally recognised

that there are really two Chilian species of Laurelia, but

the rather inadequate character of the account supplied by

Castillo and Dey has provided an excuse for an attempt to

substitute the earlier name, L. aromatica, Poir., for that

proposed by Bertero. As regards the name ZL. aromatica, it

has, however, to be pointed out that Poiret applied it, in

the first instance, to a specimen in the herbarium of Jussieu

for which he provided a brief diagnosis which indicates

that the leaves are quite entire. Tulasne, who saw the

specimen belonging to Jussieu, has stated that it is in

every respect identical with Zi. sempervirens. Moreover,

the fuller description which follows the brief diagnosis given

by Poiret appears to have been transcribed by that author

from the original description of Pavonia sempervirens drawn

up by Ruiz. With the object of preventing the recurrence

of past’ misapprehensions, we have thought it desirable to

provide here a somewhat full description of L. serrata.

In the garden at Kilmacurragh, Wicklow, the Huanhuan

has attained, during its sojourn there of over forty years, a

height of 33 ft., and has proved quite hardy ; it is therefore

likely to thrive in the milder parts of the British islands,

and should prove an attractive addition to favourably

situated outdoor collections, on account of its pleasing

‘aspect and its aromatic properties. Mr. Moore informs us

“that the climate at Kilmacurragh is very moist and_ there

are spring frosts, but as vegetation is late in starting, plants

generally escape injury. The Huanhuan is of a somewhat

stiff habit of growth and the leaves are thick and firm, so

that shelter is an essential condition for its successful

cultivation; the Kilmacurragh example has thriven ad-

mirably on a raised bank in good, stiff loam, well sheltered,

but not overhung by treesand shrubs. It is very difficult

to get cuttings of L. serrata to root, and the only available

method of propagation is by layers,

The group of Rhododendrons to which &. concinnum,

Hemsl., and the form here figured belong, includes a

considerable number of very closely allied plants, and

Mr. Hemsley explains that in proposing a distinctive name

for the subject of our plate he does so with the object of

avoiding possible confusion rather than for the purpose of

expressing a conviction that FR. coombense deserves to rank

as a species. Messrs. J. Veitch and Sons, who in 1907

communicated the flowering specimens of Lf. coombense

here made use of, have raised a large number of forms

from seed collected by Mr. E. H. Wilson in China. Most

of these forms it has been possible to match with the

herbarium specimens prepared by the same collector ; there

are, however, others of which Mr. Wilson, when gathering

the seeds, could obtain no flowering specimens. A com-

prehensive study of the whole material thus acquired is

necessary in order to lead to a better knowledge of the

extent to which seminal variation occurs, and to some

conclusion as to whether natural hybrids are present among

these obviously nearly related forms. A living plant of

the form now described, presented by Messrs. Veitch to the

Kew Collection, flowered there during the spring of 1909.

The specific name proposed for the elegant little species

here figured has reference, Mr. Rolfe explains, to the

shape assumed by the inflorescence in consequence of the

strong decurvature of the lateral sepals of the individual

flowers. In referring this plant, and the whole of the

section Cirrhopetalum to which it belongs, to the genus

Bulbophyllum, Mr. Rolfe has adopted a comprehensive view

that is admittedly unassailable on taxonomic grounds. At

the same time, the recognition of the section ees Ropetalice

as a floristic group apart from Bulbophyllum is a measure

that has, owing to the considerable number of the forms

that may without dubiety be referred to one as apart from

the other group, certain practical advantages that appeal to

cultivators, and it will probably always be found convenient

from the horticultural point of view to treat this plant as a

Cirrhopetalum. The species is a native of Sumatra, from

the eastern coast of which island it was first introduced to

the Botanic Gardens at Brussels. From that institution the

plant from which our plate has been prepared was commu- —

nicated in 1908 to Kew, and came into flower there in —

October of that year. It thrives satisfactorily under the —

tropical conditions suited to other species of the genus from

south-east Asia.

It is unfortunate that this fine Magnolia, which is a very

distinct and striking species, is not quite hardy enough to

thrive in the open air at Kew. Its large persistent leaves,

which closely resemble those of Talauwma ovata, St. Hil., and

its noble, creamy white flowers would have made it an even

notable tree than M. grandiflora, Linn., the only other

) n Magnolia at present available, a form of which is

figured at t. 1952 of this work. Both at Kew and in the

- gardens of Messrs. Veitch at Coombe Wood M. Delavayi

: succeeds very well against a wall; even the late trying

winter has not injured it at all. The species appears to be

confined to Yunnan, where it occurs at altitudes between

5500 and 7000 ft. above sea-level. In rocky places it is a

shrub about 8 ft. high, but in more favourable situations it.

grows into a tree 15-30 ft. in height. It ought to make a

NovemsBeER, 1909.

fine addition to the garden flora of the milder parts of the

kingdom, such as Cornwall, South Wales, or wherever the

large-leaved Rhododendrons thrive. The plant from which

our figure was prepared flowered at Kew in July, 1908. It

was presented by Messrs. Veitch in 1902, having been

introduced by Mr. E. H. Wilson for that firm during his

first journey in China. The Magnolias like a warm open

soil that does not readily parch. A mixture of sandy peat

with the ordinary soil is a help to them when newly planted

out.

Descriprion.—Shrub, 8 ft. high, or a small tree 15-30 ft.

high; bark lenticelled. Leaves ovate, ovate-oblong or

elliptic, somewhat mucronulate and obtuse or rounded, rarely

retuse, at the tip, rounded or obtuse at the base, 7-13 in.

long, 4—7 in. broad, persistent, coriaceous, when dry closely

and conspicuously reticulated, glabrous above except at

times along the midrib, puberulous beneath and pruinose,

the midrib prominent and pubescent, lateral nerves 11—16

on each side; petiole 2-44 in. long, plano-convex ; stipules

about 25 in. long, pubescent outside, caducous. Flowers

creamy white, odorous. Sepals 3, oblong, 34 in. long,

14 in. broad, reflexed. Petals about 7, narrow obovate or

spathulate-obovate, unequal, 34-41 in. long, 14-2 in. broad.

Stamens 3-1 in. long; filaments about 2 lin. long; anther-

cells sublinear, discrete, the connective extending beyond

The introduction into European gardens of this handsome

Pieris appears to have taken place upwards of half a

century ago, for Lemaire, writing in 1858 about what is

almost certainly the same species, states that it had been in

cultivation for some years, though its precise history was

unknown to him. Doubt has to be expressed as to whether

the plant described and figured by him in the [lustration

Horticole cited above is the same as that originally named

Novemser, 1909.

Andromeda formosa by Wallich, for Wallich’s plant has

several ovules in each cell of the ovary, whereas the plant

of the Illustration Horticole according to the description

and the figure has only one ovule in each cell. Apart from

this there is no reason to question the identity of thetwo. In

the Genera Plantarum Pieris formosa is placed in the section

Portuna, which is characterised as follows :—Sepals valvate

in bud, coriaceous; seeds almost all pendulous, sometimes

winged ; leaves coriaceous, serrate ; racemes simple, axillary,

or paniculate at the ends of the branches; bracts and

bracteoles caducous. The same section includes P. japonica,

D. Don, and P. floribunda, Benth. et Hook. f. (Andromeda

floribunda, Pursh), both of which are much smaller in

stature, with smaller leaves and inflorescences.

P. formosa is a native of the Eastern Himalaya, from

Nepal to Bhotan, at elevations of from 6000 to 10,000 ft., of

the Ghombunda Hills in Assam, and of Manipur. It has

also been recorded from Yunnan in South-west China, and

specimens of apparently the same species have been collected

in Hupeh, Central China, by Henry. At Kew this shrub

appears to be capable of withstanding all but the severest

frosts. An old plant was cut to the ground in February,

1895, but afterwards sprang up again, and survived the

winter of 1908-9 without injury. At the same time it

certainly prefers warmer conditions, especially in spring,

and is seen-at its best as it grows in gardens in the south-

western parts of England; at Pentillie Castie, for example,

there is a specimen 20 ft. high and 30 ft. through. The

plant from which the figure now given has been prepared

was raised from seed sent from the Royal Botanic Garden,

Calcutta, in 1902; this plant, although only about 4 ft. high,

flowered profusely in May, 1908. Like most of its allies,

P. formosa prefers a peaty soil, but will, nevertheless, thrive

excellently in a warm, open loam, free from calcareous

matter, In a position where it is not liable to suffer from

dryness at the root. Seeds afford the best means of

increase.

Descriprion.—Shrub or small tree, reaching 20 ft. in

height, old branches with somewhat peeling bark, twigs

glabrous. Leaves somewhat clustered at the ends of the

twigs, lanceolate, oblong-lanceolate or elliptic-oblong, 2-5

in. long, 3-12 in. broad, acuminate, base often rather

rounded, finely serrulate, coriaceous, quite glabrous,

shining; petiole 3-5 lin. long, usually dark red, as are the

young leaves and the buds. lowers pendulous in terminal

spreading or drooping panicles 6 in long and broad ; rachis

glabrous or finely puberulous, flowering twigs almost

glabrous; bracts lanceolate, often somewhat shorter than

the pedicels, soon deciduous; pedicels about 24 lin. long,

with a pair of small bracteoles near the middle. Calyz-

lobes valvate in bud, coriaceous, ovate-lanceolate or ovate,

14-2 lin. long, subacute, finely puberulous or glabrous.

Corolla urceolate, white or tinged with rose, 3}—4 lin. long,

shortly and bluntly 5-lobed. Stamens 10, included; fila-

ments sparingly hairy, dilated at the base; anthers retrorsely

2-spurred on the back. Ovary depressed globose, about

1 lin. across, 5-celled, each cell with several ovules; style

rather shorter than corolla. Fruit globose or ovoid-globose,

2-3 lin. in diameter. Seeds fusiform, faintly 3-quetrous,

1-1} lin. long; testa lax.

The Cotoneasters as a rule succeed particularly well at

Kew, and the species which forms the subject of our plate

is no exception to this rule. It has very little beauty of

flower, for only one or two flowers are open at the same

time on individual corymbs, and the petals of these fall

almost immediately. It is nevertheless an attractive garden

shrub by reason of its large bullate leaves and its abundant

crop of brilliant red berries. In September, when these

berries are ripe and cover the upperside of its long

arching shoots, there are few hardy shrubs that are more

ornamental.

C. moupinensis is a native of Western China, and was

originally discovered near Moupine by the Abbé David in

1870. It was found again in 1897 near Tachienlu, not far

November, 1909.

from Moupine, by a correspondent of Mr. M. L. de Vilmorin,

and was once more met with at a later date in the same

neighbourhood by Mr. E. H. Wilson. The seeds, numbered

2123, received by Mr. de Vilmorin, yielded a number of

plants on which Mr. Bois has based the account of his

(. bullata ; a specimen taken from one of these plants was

communicated to the herbarium at Kew in 1902 by Mr. de

Vilmorin, who in 1905 presented to the Kew collection a

living example, now a vigorous bush 6 ft. high, from which

has been taken the material on which t. 8284 and the descrip-

tion by Dr. Stapf have been based. With this material

the specimen (sem. 2123) communicated in i902 exactly

agrees. But that specimen and the specimens taken from

the plant now figured also agree with the specimen on

which the late Mr. Franchet based his original account of

C. moupinensis, for an opportunity of examining which we

are indebted to the courtesy of Mr. Lecomte, except for the

fact that the number of flowers and fruits in each corymb is

much greater in Mr. de Vilmorin’s plant than in that

gathered by the Abbé David. But the suite of specimens

vollected near Tachienlu, within a very limited area, by

Mr. Wilson prove that this character is quite unstable, and

Dr. Stapf is therefore led to conclude that C. bullata, Bois,

is only a form, not sufficiently distinct to be considered a

variety, of C. moupinensis, Franch. There is in the Kew

collection a specimen presented by Mr, de Vilmorin as

C. moupinensis, which agrees exactly with the Abbé David’s

given in Mr. de Vilmorin’s “Fruticetum ” seems to be refer-

able to the type rather than to the floribunda form here de-

picted. It has, however, to be remarked that both Bois and

Schneider lay stress on the shape of the calyx-lobes which

they describe and figure as rounded in C. bullata, instead of

triangular as in typical C. moupinensis. But an examina-

tion of Mr. de Vilmorin’s specimens, both the dried and the

living, of the form on which C. bullata was founded shows

that they are just as triangular as in the type of Franchet’s

species. The indumentum of the receptacle varies from

“uniformly slightly villous” to ‘slightly villous below,

nearly glabrous above.” The abundant crop of seeds affords

a ready means of increase of this plant, and it can also be

propagated by layers. |

Descriprion.—Shrub, twigs adpressed hirsute at length

becoming glabrous, bark chestnut-brown or tawny. Leaves

ovate- to oblong-elliptic, base obtuse or rounded, apex acute

or sharply subacuminate, 2-3 in. long, 1-13 in. broad, dark

green and sparingly adpressed hirsute but soon becoming

glabrous above, beneath thinly yellowish or grey hirsute,

lateral nerves oblique, 6-8 on each side, sunk above,

prominent beneath, bullate between the nerves; petiole

short, about 1 lin. long, hairy. Corymbs 20—30- (occasion-

ally more-) flowered, 14-24 in. across, greyish hirsute with

adpressed hairs, at the tips of leafy twigs 3-13 in. long,

rarely longer; pedicels short, reaching 14 lin. in length.

_feceptacle in flower turbinately hemispheric, laxly pilose

throughout or almost glabrous above, 14-2 lin. wide.

The genus Cephalotacus, as limited by Dr. Pilger in

1903 in the Pflanzenreich, includes six recent species

inhabiting Eastern India, Burma, China and Japan. The

&.. - form distinguished by Siebold and Zuccarini as C. peduncu-

ie lata is considered by Pilger to be only a variety of C.

r drupacea, and wild specimens in the herbarium at Kew,

which are intermediate in character between the two, appear

to justify this conclusion. Cephalotaus differs from the

more nearly allied genera in having a pair of ovules on

each scale, and Torreya nucifera, Sieb. and Zucc., the

herbarium specimens of which are extremely like those of

C. drupacea, may be most easily distinguished by its

towards the tip. The plant from which the figure now

eiven has been prepared has long been in the collection at

Kew. It is a spreading bush, now 10 ft. high and 15 ft.

through, furnished to the ground with luxuriant dark

green foliage. In its bolder leaves and larger fruits it

provides an agreeable contrast with the common Yew, and

is very well adapted for semi-shaded places in the garden

or as part of the undergrowth in thin woodland. The

fruits are not produced plentifully every year, but they

usually occur in sufficient quantity to afford an adequate

and convenient means of increase. Any good soil suits the

species; the chief point to be kept in mind in its cultivation

is that it loves abundant moisture.

Descrierion.— Tree, dioecious and glabrous throughout,

in the warmer parts of its area reaching a height of 35 ft.,

in cooler tracts, as in the Kew collection, rather a branching

shrub about 10 ft. high. Leaves persisting, alternate and

spirally attached, but assuming a position bringing them

The genus Kitchingia includes some ten species, all of

which, except the one here figured, are certainly natives of

Madagascar. The plant now described was raised from a

cutting presented to Kew in January, 1908, by Mr. G.

Bouvet, Director of the Jardin des Plantes at Angers; it

_ resembles in habit some species of Sedum (the stems creep

on the ground, rooting freely at the nodes), and now forms

a patch some 12 in. across. In transmitting the plant

Mr. Bouvet stated that the species appeared te have been

originally introduced with other plants sent from Madagas-

car to Dr. Bontemps of Saumure. Since then, however,

Mr. Bouvet has learned that the original plant was purchased

in Belgium, and that its origin is not definitely known,

From the fact that all its congeners are Mascarene there is,

however, hardly room for doubt that K. uniflora is also a

Novemser, 1909.

pepe

native of Madagascar. There is, indeed, in the herbarium

at Kew a specimen collected by the late Rev. R. Baron in

Northern Madagascar (Baron n. 6466), growing amongst

moss and probably on a tree, that appears to be no more

than a reduced form of our plant. The leaves of Baron’s

specimen are nearly orbicular, very obscurely crenate and

only 24-3 lin. long, while the flowers are only 8 lin. long ;

the staminal insertion and the shape of the carpels are,

however, exactly as in kK. uniflora. All the flowers

originally sent by Mr. Bouvet and all those that have been

produced at Kew have been solitary as shown in t. 8266,

but we are informed by Mr. Bouvet that his plants which

in 1908 had for the most part only solitary flowers, bore

3-flowered inflorescences in 1909. Normally the epipetalous

stamens have longer filaments than the episepalous ones, and

the total number of stamens is eight. But the absolute

length of the stamens is subject to some variation, and

occasionally some of the stamens may become much reduced

or may even be suppressed. In the flowers sent by Mr.

Bouvet in 1908 the shorter stamens almost reached the

mouth of the corolla, while the longer ones were slightly

exserted; in the specimen which flowered at Kew in 1909

the shorter stamens only reached the middle of the corolla, — ,

while the longer only exceeded them by the length of the

anthers, and were also included. Mr. Bouvet informs us

that among the flowers examined by him in 1909 he has

found four with only six perfect stamens, and one with only

five. Designating the stamens long, medium or short,

according to whether they reached the mouth, the middle,

or even a still lower level in the corolla tube, he has

observed the following combinations :—(a) Five long, one

medium; (6) four long, two short; (c) three long, three

short; (d) one long, two medium, two short; (e) two

medium, four short. The leaves of K. uniflora are thick

and fleshy, glaucous green with reddish margins; the

young stems also are red. Grown in a pan or a suspended

basket in a mixture of peat and loam in a moist tropical

house the plant increases rapidly. It flowers in spring.

Descriprion.—Herb, stems prostrate and rooting at the —

nodes, glabrous. Leaves opposite, obovate, obtuse, 1-2- —

crenate along each side, 4-8 lin. long, 3-5 lin. broad, —

fleshy, bright green; petioles 4-1 lin. long, rarely longer.

Decemeber, 1909.

No climbing plant ever introduced to Great Britain is

more generally cultivated than the subject of our plate.

Supporting itself on walls without artificial aid, by the —

viscous at first capitate but ultimately disk-like tips of its

tendrils, it gives little trouble to grow, and is now more

frequently planted as a creeper on town and suburban

houses even than the Ivy. The leaves acquire the most

beautiful of autumn tints, and, being deciduous, do not

produce the dark winter effect that in some places renders

Ivy unsuitable. Nearly allied to the familiar Virginian

Creeper, Parthenocissus guinquefolia, which also has viscous

tendril-tips, the plant here figured, when brought into

general cultivation in 1868 by Messrs. J. Veitch and Sons,

was distributed as Ampelopsis Veitchii and A. japonica.

Quite recently, authorities so careful as Koehne and

Graebner have once more endeavoured to discriminate

between these two plants, but it is generally conceded that

they represent no more than two states of a single species

for which the most familiar garden name is Ampelopsis

Veitchti. In works which accept the view enunciated in

the Genera Plantarum, where the genus Vitis is made to

include all the Ampelidaceae except the species of Pteris-

anthes and of Leea, our plant is known as Vitis inconstans,

a name which is, however, somewhat less familiar than that

under which it was issued by the Messrs. Veitch. But this

view is now almost universally considered too comprehen-

sive, and writers who, like Mr. Sprague, follow the careful

monograph by Planchon, where the Vitis of the Genera — ;

Plantarum is subdivided into nine distinct genera, are pre-

cluded from using either of these familiar names. Our

plant is neither a Vitis, in the narrower sense in which

that name was originally and is now again more satis-

factorily employed, nor a genuine Ampelopsis; it is a

member of the genus which Planchon has termed Partheno-

cissus, readily distinguishable from the other genera of

Ampelidaceae grown out of doors in this country by having

viscous tendril-tips, by the absence of tendrils from the

inflorescence, and by the glandular hypogynous disk being

entirely adnate to the ovary. P. tricuspidata has shoots of

two distinct kinds—long shoots and short. The long shoots

bear several leaves with leaf-opposed tendrils and axillary

branchlets, two successive leaves having a tendril opposite

to them, and the third a branchlet in its axil. The short

shoots produce only two leaves in each year; these leaves

are nearly opposite, and each has a branch or bud in its axil;

the shoot itself may end either in a tendril, which soon dis-

appears, or ina cyme. Three combinations are met with as

regards the axillary branches. There may be a cyme in

each axil; or there may be a cyme in the axil of the lower

and a long shoot in that of the upper leaf; or, finally, there

may be a vegetative bud in the lower axil, which will con-

tinue the growth of the short shoot in the following season,

and a cyme in the upper. ‘Trifoliolate leaves are character-

istic of young plants; in this condition P. tricuspidata bears

a superficial resemblance to the juvenile state of the Poison

Ivy, Rhus Toxicodendron, and recently a good deal of

unnecessary alarm has been caused by the confusion of the

two ina popular article. The plant now figured is quite

harmless, and is readily distinguished by its leaves being

mostly simple; the Rhus never has simple leaves. P.

tricuspidata is most easily cultivated, and will thrive in

almost any soil. Propagation is effected by means of

cuttings placed in gentle heat. The young plants should

be grown in pots until planted out in permanence, as they

do not transplant well.

Drscriprion.—Shrub, climbing by means of short, much-

branched, leaf-opposed tendrils with discoid viscous tips ;

twigs of two kinds, long with several leaves and short with

2 nearly opposite leaves. Leaves polymorphic, cordate and

5enerved at the base, rather coarsely crenate-serrate, the

_ teeth usually rounded, mucronate, less often acute, glabrous

and shining above, finely puberulous on the nerves beneath,

those of the long shoots mostly small, ovate, entire or

slightly 3-cuspidate ; the lower leaves of long shoots and

those of the short shoots much larger, up to 10 in. long,

with long petioles, nearly orbicular, markedly 3-lobed or

occasionally 3-foliolate, in young plants still larger and

usually 3-foliolate; stipules lanceolate, membranous, de-

ciduous. Cymes mostly from the short shoots, some also

{rom low down on the long shoots, their arrangement regu-

lated by the mode of growth which is sympodial at two

succceding nodes and monopodial at the third; bracts mem-

branous; flowers greenish. Calyx cup-shaped, somewhat

truncate. Petals 5, induplicate-valvate, inflexed at the tip,

spreading in flower, with inturned margins, ovate-oblong,

about 2 lin. long. Stamens erect, eppesite the petals ;

anthers introrse, glandular on the back. Disk adnate to

lower half of ovary, 5-grooved, glandular. Ovary 2-celled

cells 2-ovuled ; ovules collateral, erect ; style less than 1 lin

long, stigma minute. Berry pruinose, 1-2-seeded.

Asparagus tetragonus is a member of the group of species

of which A. racemosus, Willd., is the best known example.

The general resemblance between these two species is con-

siderable, and it has even been suggested that the subject

of our plate may be no more than a variety of Willdenow’s

species, which is a native of Tropical Asia and Africa.

at A. tetragonus, which is a native of South Africa, and

was first collected by Mund and Maire in Cape Colony, has

broader perianth segments, the outer ones at least being

almost laciniate, than is the case in A. racemosus where the

perianth segments are oblanceolate, somewhat acute, and

quite entire. The spines of the two species also differ some-

what, those of A. tetragonus being stout and decurved,

whereas those of A. racemosus are often straight and

slender. In both species the cladodia vary considerably ;

in the case of A. tetragonus some are compressed with a

thick prominent rib on both faces and others are distinctly

DecemBer, 1909.

trigonous; the majority, however, are almost equally

tetragonous. The plant from which the figure now given

has been prepared is one that has been grown for many

years in the Succulent House at Kew, where, planted in a

shallow border, its stems attain a length of over 10 ft.

These are woody at the base and armed with rather

formidable spines. The flowers, which are produced freely

in autumn and are very fragrant, are succeeded by red

globose one-seeded berries. Like some allied species,

A, tetragonus has a root system remarkable for the large,

whitish, watery, ovate tubers which are formed along the

principal roots, and are calculated to enable the plant to

endure prolonged periods of drought. A. tetragonus is not

difficult to grow, and is a useful plant for clothing pillars

in a conservatory.

records it from Alabama; the basis of this record is, how-

ever, a very imperfect specimen collected by Buckley in

the Alleghany Mountains, and Sargent (Sylva of North

America, vol. iv. p. 28) is probably justified in concluding

that, as no other trace of P. maritima has been met with in

this now well-explored region, the specimen obtained by

Buckley merely represents a form of P. alleghaniensis,

Porter. The nearest ally of P. maritima is P, Gravesii,

DecemsBer, 1909,

Small, from which our plant appears to differ mainly in the

shape of the leaves and in having a stone which is more or

less pointed at both extremities. The plant from which our

figure has been prepared has long existed in the Kew

collection. It flowers in May, and not only produces its

blossoms in great profusion, but keeps them in perfection

longer than most Plums do. At Kew it forms a low

spreading bush, 4-5 ft. high, and considerably more

in width. Judging by the localities in which it grows wild,

it ought to prove useful for planting in fairly exposed

places near the sea. It appears to possess a very robust

constitution, and is one of the most accommodating of

American Plums in regard to soil. It is, however, rather

subject to attack by the aphis which so frequently infects

the young shoots of Plums and causes the leaves to curl up

into shapeless masses. P. maritima produces its fruit in

sufficient quantity to afford ample means of propagation ;

it can also be budded on ordinary plum-stocks.

Derscription.—Shrub, 4-5 ft. high in cultivated speci-

mens, reaching 12 ft. in wild specimens; main branches

decumbent, the secondary erect or nearly so; bark smooth,

more or less ash-grey. Leaves elliptic or obovate, more or

Opuntia imbricata is a native of the dry interior of

Central and Northern Mexico and of the adjacent regions

to the north; its range extends through Arizona, New

Mexico and Western Texas as far north as Pikes Peak in

Colorado. For the material from which the figure now

given has been prepared we are indebted to Sir E. G. Loder,

Bart., in whose collection at Leonardslee, Horsham, a plant

which he had himself collected in Colorado in 1878 flowered

early in August, 1908. This species is a member of a

small group of Opuntias characterised by their cylindric

DecemsBeR, 1909,

stems with short ridge-like compressed tubercles and by the

sheaths that cover their spines. It is the commonest

member of the group to which it belongs in European

gardens, and was first introduced to cultivation in the

earlier years of the nineteenth century. In spite of this,

however, it is a plant whose flowers, which are very

attractive but which will only expand under the influence

of direct sunshine and unfortunately do not last long, are

not often seen in the United Kingdom. Sir Edmund Loder

informs us that his example at Leonardslee has but seldom

flowered ; when it did so in 1908 this happened during a

time of very hot, sunny weather, and individual flowers

only remained fully open during one afternoon, from about

midday till sunset.

Descriprion.—Shrub, 3—7 ft. or a small tree up to 15 ft. _

high, its trunk 5-10 in. thick with whorled spreading or —

ascending branches; twigs 2-10 in. long, about 1 in. thick,

cylindric, glaucous green, covered with compressed tubercular

The genus Ewryops includes, so far as it is at present

known, some 40 species, all of which are confined to the

African Continent and the island of Socotra. It is nearly

allied to the genera Senecio, Linn., and Othonna, Linn. ;

from the former Euryops only differs in having connate

involucral bracts which are not provided with caleycine

_ appendages; from the latter it is distinguished by the fact

that the florets of the disk are fertile. Most of the species

of Euryops have thick fleshy leaves. The species now

figured is a native of the coast region of Cape Colony,

where it is found on stony veldt from Knysna to Albany.

It is nearly allied to E. algoensis, DC., a native of the

same region which has larger leaves, villous achenes and

fewer but larger flower-heads. £. virgineus was first intro-

duced to English gardens about 1821, and can be success-

fully grown in sheltered situations in the south-western

parts of Britain. The material from which our plate has

DeceMBeER, 1909,

been prepared was communicated to Kew by Mr. T. A.

Dorrien Smith, in whose garden at Tresco Abbey, Isles of

Scilly, it thrives luxuriantly and flowers profusely in March

and April. : |
