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 BoranicaAL 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 Tarrp Sertss, 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

The Lilac here figured was introduced to European

gardens from Northern China, whence seeds reached Paris

somewhere between 1879 and 1883. The examples in the

Kew collection have been received from various sources and

under the diverse names S. Hmodi, var. rosea, S. villosa,

S. Josikaea, var. eximia, and S. Bretschneideri. In 1888 it

was in France treated as a variety of S. Emodi, Wall. ;

that species, however, differs from the subject of our plate

in having quite glabrous leaves which are much paler

beneath, with a different main-venation and a less distinct

secondary reticulation ; the panicles too are smaller and the

flowers are white. In the same year our plant was else-

where referred to S. villosa, Vahl; Vahl’s plant is, however,

a very distinct species with smaller and rounder leaves, less

copious panicles and smaller flowers of a paler colour. The

species now described is more nearly allied to S. Josikaea,

Janvaky, 1910.

Jacq., of which it has by some growers been considered a

variety, than to either of the species just mentioned ;

S. Josikaea, however, has glabrous leaves, much whiter

beneath, and has more deeply coloured flowers than our

plant, which appears amply entitled to the separate recog-

nition first accorded to it by Mr. Lemoine in 1900. Like

all Lilacs, S. Bretschneideri is fond of abundant moisture and

generous treatment at the root; it thrives well in a rich

loamy soil. The finest example in the collection at Kew is

now a handsome bush 10 ft. high and as much through, but

it promises to become considerably taller. Its fine panicles

—18 in. high and 12 in. across—are at their best in early

June when those of the common Lilac and its varieties have

faded. This feature adds greatly to the value of S. Bret-

_schneidert in the garden, and entitles it to a foremost place

among hardy flowering shrubs. It can be increased by

means of cuttings and also by seeds.

Descriprron.— Shrub, 10 ft. high or higher; branches

glabrous. Leaves elliptic or elliptic-lanceolate, acute or

acuminate, base cuneate or almost rounded, glabrous above,

beneath paler and thinly pubescent, 24—6 in. long, 1-23 in.

wide, petiole 23-6 in. long. Panicle 3-12 in. long, 38-6 in.

wide, flowers densely clustered at the nodes or at the tips of

terminal branchlets. Pedicels 0-1 lin. long, glabrous or

finely puberulous. Calyx 1-14 lin. long, campanulate,

shortly and bluntly 4-toothed, glabrous or beset with a few

seattered hairs. Corolla lilac-rose, glabrous ; tubes 5-6 lin.

long, lobes 14—2 lin. long, ovate, obtuse, spreading. Capsule

deflexed, 5-7 lin. long, 2 lin. wide, oblong-lanceolate, obtuse,

- The plant from which the drawing now given has been

prepared was obtained for the Kew collection by purchase

from the Yokohama Nursery Company in February, 1908 ;

afew days after its arrival a flowering example of the

same species was presented to the herbarium at Kew by

Mr. W. E. Ledger, who had grown it in his garden at

Wimbledon. The species, which is described in the Yoko-

hama catalogue as “a lovely tiny Iris, 4 or 5 inches high,

with yellow flowers,” is only known ina cultivated state. It

is generally assumed to be the plant described by Franchet

January, 1910.

and Savatier as J. minuta, though it has to be observed that

these authors describe the flowers as pale blue with purple

veins, and identify with their species an Iris figured in the

Honzo Zufu (vol. xxiii. fol. recto, fig. 1 recto, fig. sinistr.),

which is altogether a different plant. On the other hand,

the late Mr. Maximowicz has given, under J. minuta, an

account of a coloured drawing by Siebold of a Japanese Iris

which agrees very well with the plant now figured, and

there is no doubt that our plant is a species to which the

exhaustive description of /. minuta by Mr. Makino applies.

At Kew, J. minuta has been cultivated in a pot in a cold

frame, where it has formed grassy evergreen tufts, with

thin, wiry, freely branching and interlacing rhizomes that

emit numerous very thin roots. These roots, when ex-

amined late in the season, are found to bear many very

small potato-like tubers, in shape and size somewhat resem-

bling the eggs of ants; these tubers may serve the purpose

of the large fleshy tubers met with on the roots of certain

species of Asparagus and referred to at plate 8288 of this

work. While not a showy species, J. minuta deserves to be

included in cultivated Iris collections; it is evidently easily

kept in health, and promises to prove fairly hardy. It

flowers freely in May.

Description.— Herb, dwarf and densely tufted; root-

stock creeping and branching, with numerous slender roots

at length beset with many small tubers; shoots some

flowering, others bearing only leaves. Leaves of the sterile

shoots about 4, the lowest short and sheathing, at length

splitting into fibrils, the others narrow ensiform, the upper-

most barely twice as long as the flowering shoots, 18 in.

long, 1-4 lin. wide, acute, 5—7-nerved; those of the flower-

ing shoots all short and sheathing. Scape slender, short ;

spathe 2-valved, 1-flowered ; valves oblanceolate, narrow,

acute, with scarious margins, greenish, 14-134 in. long;

pedicel slender, 2-1 in. long. Perianth yellow, 1-14 in.

across ; tube slender, about 2 in. long; outer lobes un-

bearded, claw erecto-patent longer than the limb, yellow

within, greenish yellow externally, limb spreading or some-

what deflexed, obovate, about 5 lin. long, 4 lin. wide, yellow

and flecked with purple along the mid-rib; inner lobes

erect, shorter than the outer, rather longer than the style-

crests, claw narrow, purplish, limb obovate, retuse, yellow.

Anthers 2 lin. long. Style-arms pale yellow with crests

5—6 lin. long, lobes of the crests narrowly ovate-lanceolate,

subacute. Ovary oblong-cylindric, bluntly trigonous, 4—5 lin.

long. Capsule subglobose, about 2 in. long, 3-costate. Seeds

subglobose, yellow, 2 lin. wide, with a rather large whitish

appendage.

The genus Dipelta, founded by Maximowicz in 1877,

differs from Diervilla (Weigelia), to which it is most closely

allied, by the presence of the striking bracteoles at the base

of the ovary which grow out to form dry membranous

wings to the fruit. The species which forms the subject of

our plate differs from every other in the genus in having

the corolla widely inflated to the base; it appears, however,

to be most nearly allied to D. yunnanensis, Franch., which

differs in having entire leaves as well as in having the tube

of the corolla contracted at the base. Like D. yunnanensis,

the species now figured is a native of Western China, where

both species have been found by Mr. E. H. Wilson, growing

January, 1910,

at an altitude of 8,500 ft. above sea-level. The material

on which the present figure and description have been based

was supplied by Messrs. J. Veitch & Sons, in whose

nursery at Coombe Wood it forms a handsome shrub which

thrives excellently in the good loam characteristic of the

locality. Judging from its behaviour there, D. ventricosa

promises to be a satisfactory garden plant; it is quite

hardy, its cultivation presents no difficulties, and it is

easily propagated by cuttings.

Descriprion.—Shrub, T-18 ft. in height, young flower-

ing shoots at first pubescent, soon glabrous; internodes

about 2 in. long. Leaves opposite, lanceolate or ovate-

lanceolate, caudate-acuminate, base rounded or rarely

slightly cuneate, 2-6 in. long, 13-23 in. wide, membranous

or at length subcoriaceous, margin distantly gland-toothed,

ciliolate, sparingly strigose above, sparsely pubescent on the

nerves beneath; lateral nerves 6-7 on each side hardly

visible above; petioles slender, 4-5 lin. long, glandular

hairy. Peduneles axillary, slender, short, 1-more-flowered ;

pedicels 5-8 lin. long, sparingly glandular pubescent ;

bracts filiform, 1 lin. long or less, hairy; bracteoles 6 ;

2 very small below the middle of each pedicel, 4 large near

the base of the ovary, of these the outer pair smaller ovate,

the inner pair auriculate up to 8 lin. long. Calyx-lobes

linear-lanceolate, very acute, 3-4 lin. long, ciliolate. Corolla

tubular, 2-lpped, about 1} in. long, outside red, within

whitish orange; tube wide ventricose to the base, slightly

gibbous below in front; lobes 5, rounded, slightly recurved.

Stamens 4, didynamous, the upper pair somewhat exserted ;

filaments filiform, glabrous. Ovary 4-celled, glandular ;

style filiform, entire, glabrous. rwt crowned by the per-

sistent calyx-lobes, and hidden by the adpressed reticulate

There are at least nine species of Ourisia natives of New

Zealand, and all of them are worthy of a place in our

gardens. But though some of them have been known to

science for over half a century, the species here figured

appears to be the first that has been introduced to cultiva-

ion. It is certainly one of the finest in the genus, but it

can hardly claim to excel, from the horticultural standpoint,

O. macrocarpa, Hook. f., which differs in being more

robust, with glabrous scapes and pedicels and larger sepals

and fruit; or O. robusta, Col., also more robust, with

pubescent scapes and pedicels, with more numerous whorls

of flowers and more flowers in each whorl, but with rather

smaller corollas. It would appear indeed that O, robusta

January, 1910.

is at times mistaken for O. macrophylla, since the plant

ficured as O. macrophylla, both in Harris, New Zealand

Flowers, t. 8, and in Illustrations of the New Zealand

Flora, t. 11, appears to be really O. robusta. The example

from which the figure now given has been prepared was

obtained in 1907 from Messrs. Bees, Limited. Grown in a

pan of loamy soil and kept under glass all winter, 1t

flowered in a cold frame in April; it may prove hardy in

the warmer parts of the United Kingdom. The flowers last

for a month or more, and are succeeded by seeds which on

being sown germinate in a fortnight and afford a ready

means of increase.

Description.—Herb, perennial. Leaves radical ; petiole

tinged with purple, 1-4 in. long, somewhat concave above,

rounded on the back, pubescent, the margins ciliate ; blade

13-34 in. long, 3-3 in. wide, ovate or elliptic-ovate, obtuse,

base subcordate or rounded, margin crenately toothed,

glabrous on both sides, bright green, the veins sunk above.

Scape 3-12 in. long, at times with a pair of sessile lanceo-

late or elliptic leaves, pubescent. / lowers in 1-4 whorls,

Jong, pubescent. Calyx 3-5 lin. long, divided almost to

the slightly constricted base into 5 oblong-lanceolate lobes,

obtuse or acute with a minute apical gland, thinly pubescent

and finely ciliate. Corolla 10-11 lin. across, white; tube

hardiy longer than the calyx; throat beset with yellow

hairs ; limb oblique, flat, 5-lobed, the lobes wide obovate,

Eria rhodoptera was described by the late Professor

Reichenbach from a plant which flowered in the Pine-

apple nursery of Messrs. Henderson & Son, at Maida

Vale, in 1882. The plant, which was described as having

flowers of a pallid whitish or ochre colour, with purple

petals and purple side-lobes to the lip, appears to have been —

soon lost sight of, and its native country was unknown. Ten

years later Professor Kranzlin described as E. Laucheana

a plant, of which the native country was also unknown,

from the collection of Prince Leichtenstein at Eisgrab. A

plant of EL. Laucheana was sent to Kew in 1904 from the

Botanical Garden at Heidelberg, where there is a good and

well-grown collection of Orchids. This plant flowered at

Kew in April in a tropical house under the treatment

suitable for species of Evia, Dendrobium and Coelogyne, and

on flowering it was found to be identical with herbarium

material of a species of Eria from the Philippines and also

Janvaky, 1910.

to be the same as the earlier described FE. rhodoptera, The

species comes nearest to E. Dillwynii, of the section

Hymeneria, figured at t. 4163 of this work, but is one of

the most distinct in this section on account of its crimson

petals and lip.

Descriprion. — Herb; pseudobulbs clustered, ovoid-

oblong, 24-4 in. long, 2-4-leaved. Leaves coriaceous,

oblong-lanceolate, subacute, 43-10 in. long, 3-14 in. wide.

This handsome Coelogyne was introduced from Annam

by Messrs. Sander & Sons, St. Albans, through their

collector, Mr. Micholitz, who found it growing at an eleva-

tion of 4,500 ft. above sea level on the Laos aspect of the

Lang Bian range. It flowered first, in December, 1906, at

St. Albans and simultaneously at the Royal Botanic

Garden, Glasnevin. Another plant presented to the Kew

collection by Messrs. Sander has not yet flowered, though it

has thriven well under the cultural conditions suitable for

C. cristata, Lindl., to which it is more nearly allied than to

any other known form. The material on which the original

description was based, and that employed in preparing the

plate now given, has been supplied from the Glasnevin

plant by Mr. F. W. Moore, after whom the species has been

named. The largest flower-spike so far produced in culti-

vation has borne eight flowers. These in structure and as

regards the appendages of the lip are very like the flowers

Fesrvary, 1910.

of C. cristata, but are firmer in texture and remain longer

fresh. In habit, however, C. Mooreana differs a good deal

from C. cristata, and is much more like the Malayan

C. Sanderiana, Reichb. f. The species is likely to become

popular in Orchid collections.

Descriprion.—Herb; pseudobulbs clustered, ovoid-oblong,

obtusely 4-angled and channelled, about 3 in. long, narrowed

towards the tip, 2-leaved. Leaves long lanceolate, acute,

7-nerved, narrowed below into a petiole ; 10-20 in. long,

1}-2 in. wide, arcuate. Scapes erect, 12-16 in. long;

racemes 4—8-flowered; bracts deciduous; pedicels 1—14 in.

long. Flowers handsome, white, the disk of the lip with a

golden yellow blotch and beset with yellow subclavate

processes. Sepals elliptic-oblong, acute, faintly keeled,

1g-2 in. long. Petals elliptic, acute, 18-2 in. long. Lip

3-lobed, 14-13 in. long, base concave, pouched ; lateral

lobes oblong, incurved and embracing the column; mid-

lobe ovate, obtuse ; disk closely beset with slender processes

The downy-twigged Black Poplar of English collections

is readily distinguished from the smooth-twigged tree com-

monly grown in gardens as Populus nigra by its more

- compact, rounded, Elm-like head, and by a greater tendency — 3

to develop huge burrs on its old boles. But many forms -

intermediate in facies between these two trees are to be

met with; among these intermediates the pubescence, the —

presence or absence of which is so distinctive of the extreme

types, varies remarkably in degree and duration without

being uniformly correlated with differences in habit. The

examination of many specimens from different trees conveys

the impression that the pubescence can hardly be relied —

upon as affording a varietal character. If this conclusion —

be just, the status usually accorded to the downy Black

Frsrvary, 1910.

acuminate, base wide, cuneately rounded, rarely truncate or

slightly cordate, margin serrulate ; often at first pubescent

but soon becoming glabrors; dark green above, somewhat

paler beneath ; petiole reaching 24 in. in length, at first

downy. Male catkins 1-2 in. long ; scales wide obovate,

about 2 lin. long with a marginal fringe of segments nearly

as long; anthers usually 11-17. Hemale catkins slender,

3-4 in, long; pedicels 1-13 lin. long. Capsules ovoid,

23-34 lin. long.

The plant of Campanula Beauverdiana which forms the

subject of our illustration was raised at Kew in 1908 from

seed received from the Botanic Garden, Tiflis. The species

was described in 1905 from specimens collected on the

mountains near Mzchet, some fifteen miles from Tiflis. It

has since then been described as a variety of C. Steveni,

M. Bieb., by Dr. Bornmiiller, from material gathered by

himself on Mount Elburs in North Persia (not Mount

Elburz in the Caucasus) at an altitude of 8,500 ft. above sea-

level. In this locality it was found growing in company

with typical C. Steveni, a widely distributed species to

which, in the dried state, C. Beauverdiana bears a close

resemblance. In the living state, however, they are readily

distinguished, for the calyx of C. Steveni is without any

indumentum, while the purple-violet corolla is lobed half-

Frsrvary, 1910. :

way down and the style-arms are longer than the undivided

portion. Under his original description of C. Beauverdiana

Dr. Fomin mentions a gathering by Sintenis from Kirkpauli

in Turkish Armenia, the specimens of which were distri-

buted as C. Steveni under the number 5647. At Kew,

however, the specimens of Sintenis n. 5647 consist in part

of C. Steveni, in part of C. Beauverdiana, so that in Armenia

as in Persia the two species evidently grow together.

C. Beawverdiana is a perennial, in character much resem-

bling the native C. rotundifolia, Linn. ; it thrives well and

flowers freely under the conditions suited to that species,

and is at its best in May and June.

Descriprion.—Herb, glabrous or finely hairy, reaching

2 ft. in height, with a slender short rootstock and slender

erect or ascending stems. Leaves below oblong-ovate or

wide ovate, 24 in. long, 2 in. wide, obtuse, crenate-serrate,

narrowed into a petiole rather longer than the blade;

leaves higher up sessile, smaller than the lower, linear-

lanceolate or lanceolate, acute, sparingly glandular toothed ;

uppermost leaves linear, acuminate with a spongy tubercle

at the base below. lowers solitary or few; pedicels

slender, the longest nearly 3 in. long. Calyx with a narrow

obconic 10-ribbed tube, about 4 lin. long, beset with white

inflated papillae between the ribs; lobes narrow lanceolate,

acuminate, nearly or quite twice as long as the tube.

Corolla blue, glabrous, wide campanulate, 1; in. across,

twice as long as the calyx-lobes or rather longer ; lobes half

as long as tube. Filaments subulate, glabrous, springing

from a subquadrate, pilose base. Style divided to the

middle, the arms purple, densely hairy on the outer side.

There are in the. herbarium collection at Kew only two

wild specimens named FR. Keiskei; one of these, in flower,

was collected by the late Mr. Maximowicz on the volcanic

mountain Wunzen, in 1863; the other, in fruit, is from

Mt. Tchako, in the province of Tosa, and was communicated

, by the College of Science, Tokyo University, in 1893. The

ai now figured was obtained for Kew from a nursery in

okohama in 1908, and flowered in a pot in an unheated

frame in April, 1909. From this plant the flowering speci-

men originally collected by Maximowicz differs in the calyx-

lobes being more distinctly developed and fringed on the

margin, in the stamens and style being relatively longer,

exceeding the corolla, and in the leaves being slightly hairy

along the midrib on the upper side. The fruiting specimen

received in 1893 differs in the petioles being furnished with

two rows of long weak bristles which form a conspicuous

fringe. In other respects the three representatives of

R. Keiskei at Kew agree very closely. The species is most

nearly allied tu &. triflorum, which is figured at t. 19 of the

Rhododendrons of the Sikkim Himalaya. Though the plant

has not yet wintered in the open air, it promises to be

hardy ; if this be borne out by experience, the chief value of

the species will be in adding a new yellow-flowered ever-

green ‘Rhododendron to the out-door garden. It should

thrive under the conditions suited to other species; a soil

preferably peaty, that is free from lime and abundantly

supplied with moisture. ee

the branches when young sparingly lepidote. Leaves

lanceolate, including the petiole 14-3 in. ong, somewhat

acute, base .cuneate, rounded or occasionally subcordate,

sparingly and obscurely lepidote above, paler: beneath and

For the material on which the figure of this beautiful

shrub given at plate 8301 has been based, Kew is indebted

to Mr. T. A. Dorrien Smith, in whose garden at Tresco

Abbey, Isles of Scilly, it grows luxuriantly in the open,

though in most parts of the British Islands it is not hardy.

The genus Agonis to which the plant belongs ineludes fifteen

species, all of which are limited to Western Australia. In

the Flora Australiensis the late Mr. Bentham has divided

the genus, which as a whole was formerly deemed, owing to

its jalternate leaves and to the relative lengths of the

stamens and petals, a section of Leptospermum, into two

sections. The first of these, the Taxandria, were charac-

terised by having ten stamens, regularly opposite to the

calyx-lobes and petals and by having two ovules in each

cell. The second section, the Ataxandria, were characterised

Feprvary, 1910.

by having, with the exception of A. grandiflora, twenty to

thirty stamens, none of which are opposite the centres of the

petals, with at the same time four to six ovules in each cell.

As Mr. Hutchinson points out, however, the character

derived from the number of ovules is evidently liable to

some variation, and must therefore be used with caution,

for in A. marginata, the species now depicted, while there

are ten stamens strictly opposite the calyx-lobes and petals,

there are three or four ovules in exch cell.

Descriprion.— Shrub, 6-10 ft. high, branches and small

twigs softly pubescent. Leaves obovate-oblong, obtuse or

finely mucronulate, narrowed at the base into a short petiole ;

blade $-14 in. long, 3-5 lin. wide, coriaceous, 5-nerved

from the base, margin densely pubescent with adpressed

hairs. lowers sessile, clustered, the clusters axillary, almost

globose, 10—20-flowered ; outer bracteoles wide orbicular,

densely ciliate, 2 lin. across; inner obovate, concave, keeled

on the back, white villous, 14 lin. across. Calya-tube 1 lin.

long, sparingly pubescent externally ; lobes rounded, softly

ciliate and silky pubescent, reddish purple within. Petals

with a white, glabrous, suborbicular limb, about 14 lin.

wide, and a short reddish purple claw. Stamens 10, opposite

the petals and calyx-lobes. Style glabrous, stigma capitate.

Ovules 3-4 in each cell. Fruit conglomerate, the individual

fruits opening loculicidally at the tips.

The genus Rehmannia includes six known species, all

natives of China, though one—f. glutinosa, Libosch—

extends also to Japan. It has given no little trouble to

systematic workers, and one suggested species—R. ? Old-

hami, Hemsl., a native of Formosa—has recently had to

be transferred to Gesneraceae and treated as the type

of a distinct genus. Three of the species have already

been dealt with in this work. At t. 3653, under the

synonym ff. chinensis, is given a figure of &. glutinosa;

at t. 7191 2. rupestris, Hemsl., is depicted; at t. 8177,

under the synonym R&R. angulata, a figure has been given

of a species very nearly allied to A. angulata, which,

Marca, 1910.

however, is now found to deserve separate recognition.

For the plant in question, Mr. Brown suggests the name

R. elata. It is characterised by being twice as large as

R. angulata; by having leaves with 2-6 acute entire lobes

on each side in place of having either very many marginal

teeth, or, if there be a few lobes or large teeth, by these

being again toothed; by having bracts or flowering leaves —

with long cuneate bases not broader than the lamina nearer

the apex, as against very broadly and rather abruptly

cuneate bases which are wider than any other part of the

lamina. The corolla in £&. elata is slightly larger and is

bright soft rosy purple on the lips, yellow dotted with red

in the throat; in R. angulata the rather smaller corolla is

red with a band of scarlet at the margin of the upper lip

and has orange dots inside the lower lip. The species now

figured is in somewhat like case; it has hitherto been

treated as a form of R. Piasezkii, Maxim., a native of the

northern parts of Shensi, which differs in being over 3 ft.

high, and in having subsessile bracts or flowering leaves

and purplish flowers.

Originally discovered by Mr. A. Henry about 1885 in

the neighbourhood of Ichang, and subsequently collected

by him near Nanto, R. Henryi was again met with by

Mr. E. H. Wilson somewhere in the same general region.

A share of the seed obtained by Mr. Wilson was com-

municated to Kew, in 1907, by the Director of the Arnold

Arboretum, Jamaica Plain, Mass. Plants raised from this

seed grew well under ordinary greenhouse treatment, and

flowered in 1908 and again in 1909, when the figure

now given was prepared. The species sets seeds freely,

and it may prove hardy in the warmer parts of England.

_ Descrrprion.— Herb, perennial, 6-18 in. high, simple or

branching at the base, glandular hairy throughout. Leaves

Aquilegia alpina, the species here figured, is a native of

the Alps of Dauphiné, Switzerland and Piedmont, and of

the Tuscan and Emilian Apennines. The typical form

of the species has almost straight spurs, but the degree of

curvature of the spur seems to be subject to considerable

variation, and the plant here depicted—which, in respect of

its spur, approaches A. Sternbergii, Reichb., but differs from

that species in its more robust habit and in having petals

that exceed the stamens—is perhaps rather an extreme

form than a distinct variety of A. alpina, For the material

from which our plate has been prepared we are indebted to

Mr. D. Hill, in whose rock-garden at Herga, Watford, the

plant here depicted flowered freely in the early summer of

1909. The plant was obtained by Mr. A. W. Hill on the

Pleine Madeleine, near Chandelon, in Valais, where the

species was found growing in quantity on a small level alp

bordered with low trees and shrubs, at about 5,000 ft. above

Marca, 1910.

sea-level. At the time of its collection, in the second week

in August, 1907, only a few flowers remained, and most of

the plants bore nearly ripe seed. A few plants, carefully

dug up so as to preserve the long tap-root, were, on

reaching England, potted in a mixture of sandy loam and

peat, and kept during winter in a cold frame. In the

following spring they were transferred to the rock-garden

in a mixture of loam and peat, and in a situation where

they received partial shade at different times during the

day. Seeds have been produced, and some of these have

germinated.

Description.—/ferb, perennial; stems several, erect, 1-3-

flowered, puberulous. Leaves at the base mostly twice

ternate; petioles and petiolules sparingly puberulous ; leaf-

lets rhomboid-orbicular, 1-12 in. across, trifid to the middle,

the lobes incised crenated, their ultimate segments usually

longer than broad, somewhat glaucous beneath ; stem leaves

small, trifoliolate or simple, their segments narrow. lowers

outer shorter with large anthers, the inner long with

smaller anthers; filaments linear above, eradually widening -

Examples of this pleasing Rhododendron had been a

desideratum for the Kew collection for many years, but it

was not until 1907 that a batch of plants, from one of

which our figure has been prepared, was obtained by

purchase from a firm of nurserymen in Yokohama; these

plants were actually sent as representing a variety of

R. quinquefolium, Bisset and Moore. The section Rhodo-

rastrum, to which R. mucronulatum belongs, is distinguished

by the flowers being solitary in each involucre of bracts

instead of being in trusses. The late Mr. Maximowicz, who

looked upon our plant as a variety of R. dauricum, Linn.,

states that it is readily distinguishable from typical £&.

dauricum, as it occurs in the southern portion of its area,

but that as we proceed northwards forms are found that

Maron, 1910.

exhibit a gradual transition to what may be considered the

most reduced form of the same species. The form which

may be regarded as typical A. dawricum was figured from

the garden of Mr. Woodford, Vauxhall, at t. 636 of this

work so long ago as 1803; the variety sempervirens 1s,

represented at t. 1888. The only other species belonging

to this section is the pretty &. virgatum, Hook. f., por-

trayed at t. 5060 of this Magazine. Judging, so far as it

is safe to do so, from its short existence under cultivation in

this country, 2. mucronulatum would appear to be hardy

and a good grower. With their roots in a sandy peaty

soil, our plants have made shoots 6 to 12 in. long during

the past summer. This Rhododendron is deciduous, its

leaves turning yellow before they fall; it can be increased

by means of cuttings.

Description.— Shrub, dwarf and branching; the twigs

slender and sparingly lepidote. Leaves scattered, the inter-

nodes rarely longer than the petioles, deciduous, shortly

stalked; blades thin, lanceolate, 14-3 in. long, usually

narrowed to both ends, apiculate, margins somewhat undu-

late, sparingly lepidote on both faces, but most markedly

beneath; petioles 2-3 lin. long. Flower-buds sessile,

1-flowered, in groups of 2-5 near the tips of the twigs;

scales more or less lepidote, wide, nearly orbicular, the

outer rather firm, ciliolate, about 2 lin. long, the inter-

mediate thinner, white, fimbriated, about 4 lin. long, the

mnermost 2-3 linear-spathulate, fimbriated, 5-6 lin. long.

Flowers pale reddish-purple, 13-2 in. across, shortly

peduncled. Calyx very short, with deltoid lepidote teeth.

Corolla wide campanulate, puberulous outside, but not

lepidote, epunctate within; lobes wide imbricate, rounded

and undulate. Stamens 10, declinate, alternately shorter

and longer, the longest not exceeding the corolla ; filaments

hirsute below the middle with flattish linear crisped 1-celled

hairs; anthers very dark purple. Ovary 5-celled, lepidote,

style glabrous, curved, rather longer than the longest

stamens. Capsule not seen.

The genus Pittosporum is confined to the eastern hemi-

sphere throughout the more mildly temperate and subtropical

regions of which its species, some fifty in number, are widely

spread. It is most highly differentiated in New Zealand,

which is the home of about twenty-five per cent. of the

forms so far characterised. Already seven plates in this

work have been devoted to the illustration of its species ;

tt. 1396, 1684, 2075, 3161, 4799, 5978 and 7473. For the

material from which the figure now given of yet another

form, P. Colensoi, Hook f., has been prepared, we are

indebted to Mr. T. A. Dorrien Smith, in whose garden at

Tresco Abbey, Isles of Scilly, this species, which in most

other parts of the United Kingdom is decidedly tender,

forms a handsome shrub which thrives vigorously and

flowers freely in the open. P. Colensoi is very nearly

allied to P. tenuifolium, Banks & Sol.; so many forms that

appear to be intermediate between’ the two have been

Maron, 1910.

reported that the late Mr. T. Kirk, in his “ Student’s Flora

of New Zealand,” has treated the subject of our plate as a

variety of P. tenuifolium. Mr. T. F. Cheeseman, however,

in his ‘‘ Manual” has recently vindicated the right of

P. Colensoi to the specific status accorded to it by Sir J. D.

Hooker. The chief distinguishing features of our plant, as

compared with P. tenwifolium, are the larger, more coriaceous

and flat leaves, and the more persistent bracts. Some of the

intermediate forms which lend weight to Kirk’s view are in

cultivation in this country, and specimens of such have been

communicated to the Kew herbarium from the Royal

Botanic Gardens, Glasnevin, and from the gardens of

Trinity College, Dublin, and of the Royal Horticultural

Society. The flowers of these intermediate forms are,

however, mostly like those of P. tenuifolium, while the

leaves, though approaching in texture those of P. Colensoi,

have undulate margins. For its cultivation a sandy soil

with an admixture of peat is most suitable, and the most

satisfactory mode of propagation is by cuttings in heat.

Description.—Shrub; bark blackish; twi os stout, tawny,

puberulous with long soft hairs. Leaves spreading, their

ups recurved, elliptic-oblong, oblong-lanceolate or obovate-

oblong, acute, the base usually obtuse or rounded, 14-3 in.

The genus Notylia includes about twenty species, all of

which are natives of Tropical America. While none of

them can be considered showy Orchids, most of them are

characterised by a certain degree of grace and charm; two

other species of the genus have already, on this account,

found a place in this work; J. bicolor, Klotzsch, at t. 5609,

and N. albida, Klotzsch, at t. 6311. The species now

figured, N. trisepala, Lindl., was first described over half a

century ago from a plant of unrecorded habitat which had

flowered in the collection of Mr. Van Houtte at Ghent. In

1895 a plant possessing similar characters was sent to Kew

for determination by Mr. Kienast Zolly of Ziirich; this

example was stated to have been obtained from Mexico.

The plant which forms the subject of our plate flowered in

May, 1909, in the collection of Mr. W. E. Ledger, Wimble-

don, by whom it was presented to Kew. This plant

reached Mr. Ledger from his friend Mr. Hermessen, who

had collected it at Samborne, Vera Cruz, Mexico,

Magog, 1910.

The gigantic evergreen Aroid which forms the subject

of our illustration is a native of Madagascar, where it

grows in water or in marshy places. It has, however, been

introduced thence to the Island of Johanna in the Comoros,

to Mauritius and it is also believed to Reunion, on account

of its seeds which are eaten by the inhabitants. It develops

an arboreous unbranched caudex crowned with a tuft of

large sagittate leaves. The plant from which our drawin

was made was presented to Kew in 1905 by the Royal

Botanic Gardens, Dahlem, Berlin ; placed in a bed of mud

along with the Egyptian paper reed, it has grown vigorously

and attained its present dimensions. It flowered at Kew

for the first time in May, 1909, and afterwards devel

ripe seeds, from which seedlings have been raised,

of the seeds germinated in the bottom of the spathe.

The Saxifrage which forms the subject of our illustration

is a native of the mountains of Albania and Central

Macedonia. It was introduced into cultivation in 1902,

in which year it received a first class certificate from the

Royal Horticultural Society. It is a member of the section

Kabschia, Eng]., which includes three other species with red

flowers and with somewhat similar foliage and_ habit,

S. Frederici-Augusti, S. media, and the recently introduced

S. Stribrnyi. From the first of these S. Grisebachii is

readily distinguished by having larger and more spreading

basal leaves. The two others differ from our plant mainly

in having a branched inflorescence with distinctly pedicelled

flowers. At Kew S. Grisebachii is grown in pots in a cold

frame, and is transferred in March, when it comes into

flower, to the Alpine House, where it continues in blossom

for a month or more. When grown out of doors the plant,

though quite hardy in other respects, is apt to suffer in

winter from excess of moisture.

Aprin, 1910.

Descriprion.— Herb, with short tufted densely leafy

bases, the flowering stems erect, leafy, 4—6 in. high, rather

densely beset with spreading glandular hairs. Leaves at

the base imbricate, sessile, spathulate-ligulate, with rounded

mucronate tips, 3-10 lin. long, 2—3 lin. wide, with numer-

ous intramarginal pits on the upper side, keeled beneath,

margin cartilaginous and sparingly ciliate near the base ;

stem-leaves spreading, oblong-spathulate, about 5 lin. long,

under 2 lin. wide, reddish with an abruptly narrowed green

tip, rather densely glandular hairy except at the tip.

Inflorescence racemose or subspicate, the pedicels much

shorter than the bracts. Calyx reddish-purple, densely

glandular hairy ; lobes unequal, oblong elliptic, rounded at

the tip, the largest 3 lin. long. Petals erect, elliptic-

lanceolate, purple, about 1 lin. long, barely half as wide,

ciliate towards the middle and at the base. Stamens hardly

exceeding the petals.

The Rhododendron that forms the subject of our figure,

which has been drawn from material supplied by Messrs. J.

Veitch & Sons from a plant that flowered in their nursery

at Coombe Wood in April, 1909, is one of the hardiest of the

species newly introduced from China, where it was dis-

covered by Mr. E. H. Wilson. All the plants now in

cultivation have been raised from imported seeds, but

judging by its appearance and by the behaviour of allied

species, it is probable that its propagation by means of

cuttings may be successfully accomplished. R. Harrovianum,

which flowered at Coombe Wood for the first time in 1907,

has grown well there under conditions adapted to Rhodo-

dendrons in general; a peaty, sandy soil and abundant

moisture. In addition to R. heliolepis, Franch., to which,

as Mr. Hemsley points out, it is nearly allied, our plant may

also be compared with R. coombense, Hemsl., figured at

Aprit, 1910,

t. 8280 of this work, from which it differs in its longer

leaves, its larger, violet-purple flowers, and its exserted

stamens.

Descriprion.— Shrub, 2-3 ft. high; branches straight,

rigid, at first lepidote; internodes nearly as long as the

petioles. Leaves scattered, persisting, coriaceous, the upper

spreading ; blade narrow lanceolate, 14-3 in. long, slightly

apiculate, cuneate at the base, the margin recurved, dark

green shining smooth and with the midrib sunk above,

beneath closely lepidote with fine scales and with a stout

raised midrib; petiole rather stout, 2-4 lin. long. Flowers

pedicelled, in clusters of 3-5 at the tips of the branches;

pedicels rather stout, 4-3 in. long, reddish and dotted with

white scales. Calyx very short, faintly lobed or almost -

truncate. Corolla campanulate, 3-1 in. long, lobes broad,

tube deep reddish-purple and dotted with white scales

outside in the lower part, higher up like the lobes outside

violet-purple, within corolla uniformly violet-purple save

for yellowish blotches on the upper lobes. Stamens 10,

exserted, alternately longer and shorter, the longest 14 in.

in length, filaments with a band of longish spreading hairs

above the base but below the middle. Ovary 5-celled,

closely lepidote ; including the quite glabrous style 14-14

in. long. Capsule not seen.

The genus Dipelta has, owing to the absence of complete

material, never hitherto been fully described. The late Mr.

Maximowicz, by whom it was founded on specimens of the

species here illustrated, could only report of the fruit, which

Aprin, 1910.

we now know to be a small dry capsule, concealed within

the scarious accrescent bracteoles, as “said to be a red

edible berry.” Perfect seeds were sent to England in

December, 1904, by Mr. E. H. Wilson to Messrs. J. Veitch

& Sons, but none exist in the herbarium at Kew. These

seeds, gathered at altitudes of from 6,500 to 8,000 ft. above

sea level in Western China, were sown by Messrs. Veitch

early in 1905, and produced plants from one of which came

the material from which our figure has been prepared.

Three other species of Dipelta have been described;

D. yunnanensis, Franchet, D. elegans, Batalin, and D. ven-

tricosa, Hemsl., all from Western China. In the herbarium

at Kew there are specimens in fruit of yet another form

discovered by Mr. A. Henry in Hupeh in Central China.

This is noted by Henry as possibly a new species; it is a

tree 10-40 ft. high, and has larger and much broader leaves

than D. floribunda, to which it is most nearly allied, and of

which the late Professor Batalin considered it to be a state.

This doubtful form, like D. yunnanensis and D. elegans, 1s

not yet in cultivation, but the herbarium material available

does not indicate that any one of the three is superior as an

ornamental plant to the species now figured, or to D. ven-

tricosa, figured at t. 8294 of this work. In the nursery of

Messrs. Veitch at Coombe Wood, D. floribunda forms a tree-

growing bush of rounded habit about 4 ft. high, bearing in

general appearance a resemblance to one of the Bush

Honeysuckles, or to a Diervilla. It requires a good, loamy

soil and can be increased by cuttings. It is quite hardy,

and flowers during May. 4 : :

Dersorwrion.—Shrub often 10-16 ft. high, in habit

recalling some of the Diervillas; branches long, rather

slender, at first puberulous: internodes mostly shorter than

the leaves, Leaves opposite, without stipules, short-petioled,

thin, deciduous, lanceolate, ovate-lanceolate, or ovate, often

2-4 in. long, acute and acuminate, somewhat cuneate or

rounded at the base, entire, at first puberulous but soon

glabrescent, rather paler on the underside; main nerves

about 4 on each side, somewhat hairy at first, the fine

reticulate venation translucent ; petioles 2-3 lin. long.

Flowers clustered in the leaf-axils ; peduncles short, usually

2-leaved and 3-6-flowered ; pedicels slender, 5-8 lin. long,

puberulous. Bracts linear, puberulous, 3-5 lin. long, soon

disappearing. Bracteoles 6, dissimilar; the lowest pair

below the middle of the pedicel very small, opposite, soon

disappearing ; the remaining four close-set near the base of

the pistil, persistent, accrescent, ultimately scarious, strongly

veined ; of these the two outer or lower anterior and posterior,

both smaller than the two inner or upper, but themselves

unequal; the anterior lower ovate, obtuse, wide-based,

embracing the pedicel and about 8 lin. long, the posterior

similar but only about 3 lin. long; the two upper or inner

rounded-oblong, slightly oblique, auriculaeform, peltate, 3-1

in. across in the widest part when mature, and quite conceal-

ing the capsule. Calyx limb 5-partite, lobes nearly equal,

linear, about 24 lin. long, glandular, very pointed, persistent.

Corolla pale rose, inflated tubular, 2-lipped, about 14 in.

long; tube narrowed below the middle, cylindric; lobes

nearly equal, rounded-oblong, spreading, about 5 lin. long ;

lower lip marked with orange lines. Stamens 4, didynamous,

included. Ovary inferior, hirsute, 4-celled, with 2 fertile

l-ovuled cells and 2 sterile cells with several imperfect

ovules in each; style filiform, glabrous, somewhat exserted,

Fruit (only seen unripe) angled, tipped by the persistent

calyx lobes, about 8 lin. long, hidden by the accrescent

The subject of our plate is the noblest of the Cornels. It

is met with on the Pacific coast of North America from

British Columbia and Vancouver Island to Southern Cali-

fornia, and is common on the Coast Mountains down to

Monterey. In the most favourable conditions, and especially

in the Redwood forests of Northern California, it attains a

large size; one tree is recorded as reaching a height of

100 ft. Professor Sargent and Miss Eastwood speak of it

as one of the most beautiful of trees, gorgeous in autumn

with its red fruits and brilliantly coloured foliage; a recent

writer in the Gardeners’ Chronicle says that on this account

the tree is spared even by the settler. The involucre, often

loosely spoken of as the i eae is at times 6 in. across, with

individual bracts 23 in. wide. The first botanist to discover

Apnit, 1910.

the species was Mr. David Douglas, about 1826; at that

time it was believed to be only a form of C. florida, and it

was not recognised as distinct till it was rediscovered by

Mr. Thomas Nuttall, some ten years later, during a journey

to the Pacific coast. In the 1837 elephant folio edition of

the Birds of North America, which consists of plates only,

t. 367 is devoted to Columba fasciata, with which is asso-

ciated a branch of this Cornel. In the 1842 edition of the

same work, which is accompanied by letterpress, Audubon

explains his indebtedness to his friend Nuttall for the infor-

mation that the berries of this hitherto uncharacterised tree

form a staple food of this particular pigeon. In publishing

the technical description added by Nuttall to his notes,

Audubon took the opportunity to dedicate the species to his

friend.

There is no indication that seeds of C. Nuttallii reached

England at the time of its discovery by Douglas, but we

learn from Audubon that on its rediscovery by Nuttall seeds

were transmitted to Lord Ravensworth, and further, that

information had reached America that these seeds had

germinated. In spite, however, of its introduction seventy

years ago, C. Nuttallii has never been common in this

country, and it certainly is not so amenable to the artificial

conditions of cultivation as most of the dwarfer Cornels are.

During the spring of 1909, however, the species flowered at

Kew, in the garden of Mr. B. E. C. Chambers at Haslemere,

and with Messrs. Veitch & Sons at Coombe Wood. The

Kew plant, from which our main figure has been made, was

purchased from a French nurseryman in 1904, and is now

5 ft. high and quite healthy ; during the past season it has

made shoots | to 14 ft. long. It is growing in a sandy loam

to which some peat and decayed leaves have been added.

Our experience with this Cornel! has not been sufficiently pro-

longed to justify a dogmatic statement as to its treatment,

but we should recommend for it a well-drained loamy soil

abundantly reinforced with decayed leaves—the ordinary

“ leaf-soil”” of the gardener, a sunny, sheltered position, and

attention to the matter of watering whilst the plants are young

and the root system is not extensive, A heavy cold soil is

probably as ill-suited for it as a very dry sandy one. Perhaps

the finest plant of C. Nuttallii inthis country is one in the

garden of Mr. Chambers, who supplied from it the fruit

depicted in our plate; it is a small tree, about 15 ft. high,

with a single stem. Mr. Chambers informs us that he finds

the number of bracts in an involucre to vary from 4 to 8.

Judging by our six years’ experience, the species appears

to be hardy enough, except that the succulent tips of the

shoots are sometimes cut back. This seems to expose it to

fungoid attacks, and in this way a number of young plants

have been lost at Kew. a

the species was Mr. David Douglas, about 1826; at that

time it was believed to be only a form of C. florida, and it

was not recognised as distinct till it was rediscovered by

Mr. Thomas Nuttall, some ten years later, during a journey

to the Pacific coast. In the 1837 elephant folio edition of

the Birds of North America, which consists of plates only,

t. 367 is devoted to Columba fasciata, with which is asso-

ciated a branch of this Cornel. In the 1842 edition of the

same work, which is accompanied by letterpress, Audubon

explains his indebtedness to his friend Nuttall for the infor-

mation that the berries of this hitherto uncharacterised tree

form a staple food of this particular pigeon. In publishing

the technical description added by Nuttall to his notes,

gvauben took the opportunity to dedicate the species to his

riend.

There is no indication that seeds of C, Nuttallii reached

England at the time of its discovery by Douglas, but we

learn from Audubon that on its rediscovery by Nuttall seeds

were transmitted to Lord Ravensworth, and further, that

information had reached America that these seeds had

germinated. In spite, however, of its introduction seventy

years ago, C. Nuttallii has never been common in this

country, and it certainly is not so amenable to the artificial

conditions of cultivation as most of the dwarfer Cornels are.

During the spring of 1909, however, the species flowered at

Kew, in the garden of Mr. B. E. C. Chambers at Haslemere,

and with Messrs. Veitch & Sons at Coombe Wood. The

Kew plant, from which our main figure has been made, was

purchased from a French nurseryman in 1904, and is now

5 ft. high and quite healthy ; during the past season it has

made shoots 1 to 14 ft. long. It is growing in a sandy loam

to which some peat and decayed leaves have been added.

Our experience with this Cornel has not been sufficiently pro-

longed to justify a dogmatic statement as to its treatment,

but we should recommend for it a well-drained loamy soil

abundantly reinforced with decayed leaves—the ordinary

ve leaf-soil ” of the gardener, a sunny, sheltered position, and

attention to the matter of watering whilst the plants are young

and the root system is not extensive. A heavy cold soil is

probably as ill-suited for it asa very dry sandy one. Perhaps

the finest plant of C. Nuttallii in’ this country is one in the

garden of Mr. Chambers, who supplied from it the fruit

The handsome Cymbidium here depicted, which is

perhaps the most beautiful member of the genus, was

first met with in Annam by Mr. G. Bronckart in February,

1901, growing along ravines and in sandy soil at elevations

of from 4,000 to 5,000 ft. above sea-level. Later in the

year one of Bronckart’s specimens, accompanied by an

excellent painting of the plant, was presented to Kew by

Mr. G. Schneider; on these the original description of the

species was based. According to Bronckart’s field note

the plant as met with by him is always terrestrial; the

spikes in wild plants are from 3 to 44 ft. in length and

bear each from ten to fifteen light-red flowers. Living

plants were subsequently sent to this country. In 1904

the species was again met with in Annam by Mr. W.

Micholitz when exploring on behalf of Messrs. Sander &

Sons, and again dried specimens, with spikes said by

May, 1910,

Mr. O’Brien to give evidence of having had seven or

eight flowers, and living plants once more reached this

country. The plants of this second consignment were

distributed under the name C. Sanderi, which name,

however, cannot now be taken up. In February, 1908, a

fine flower spike was presented to Kew by Mr. J. Gurney

Fowler, from a plant in his collection at Glebelands, South

Woodford, and a living specimen which flowered at Kew

in March, 1909, and from which our illustration was

prepared, was presented to the collection by Messrs. Sander.

The colour of the sepals and petals varies in cultivated

plants from white to rose, and there are forms in which

the spots on the labellum are even darker than is shown

in our plate. The species thrives well under the treatment

that best suits C. grandiflorum and C. Tracyanum ; the

temperature of a warm greenhouse, a compost consisting

of two parts fibrous loam and one part leaf soil with a

sprinkling of silver sand and small potsherds, Liberal

supplies of water should be afforded whilst growth is being

made; thereafter the soil should be kept dry for a few

weeks.

The figure of the handsome Primu/a which forms the

subject of our plate has been prepared from material

supplied in May, 1909, by Bees, Limited, by whom the

species was introduced to cultivation through their collector,

Mr. G. Forrest, whose name has been associated with the

plant by Professor Bayley Balfour. The species was met

with by Mr. Forrest on the eastern flank of the Likiang

range in North-western Yunnan at from 9,000 to 11,000

ft. above sea-level. According to him, it is usually found

growing in the crevices of dry shady limestone cliffs. It

has a long, very tough woody rootstock, with a much

tapering base, reaching a total length of 2-3 ft., only

2-3 in. being enclosed in the rock. The free portion is

pendulous, except for a few inches at the tip, where it turns

outwards and upwards, the upper two-thirds being clothed

with the remains of the leaves of former years which, at

the apex, form a dense matted mass. This extensive cover-

ing, taken in conjunction with the fact that behind the

larger specimens the rock has been scored and worn into

May, 1910.

grooves over an inch deep by the motion of the whole

plant in the breeze, seems to indicate that some individuals

must reach a considerable age. P. Forresti: in habit

greatly resembles P. bracteata, Franch., and P. bullata,

Franch., both of which also affect limestone rocks, and to

both of which it is morphologically very nearly allied.

From the former our species is readily distinguished by

the corolla tube exceeding the calyx, by the longer scapes,

and by the cordate bases of its larger upper leaves; from

the latter it is easily separated owing to the fact that the

bracts, pedicels and calyx are not farinose. The leaves

when young are sulphur-yellow on the underside, but

become green beneath as they mature. The plants growing

at Kew have proved healthy in a cold frame; whether

they may prove hardy in the open it is not yet possible

to say. They have thriven well in a loamy soil, forming a

many-crowned tuft.

The Southern Beeches, at one time considered congeners

of the Northern ones, are now usually treated as belonging

to a distinct genus, Nothofagus, which includes 17 species,

whereof 8 are South American, 6 belong to the New Zealand

flora, and 3 are Australian or Tasmanian. These southern

species differ from the members of the northern genus

Fagus in that the male flowers are solitary, geminate, or

in threes, while the fruit, which is relatively small and

contains 1-3 nutlets, usually has the 2-4 involucral valves

with transverse entire toothed or lobed scales. They are

evergreen or deciduous trees or shrubs with usually very

small leaves.

May, 1910.

Nothofagus antarctica is widely spread in temperate

South America from lat. 38° S. to Tierra del Fuego,

where, as in Patagonia, it and the evergreen J. betuloides

are the dominant trees. But while NV. antaretica, in one

or other of its forms, has several times been introduced to

the gardens of Great Britain—its earliest introduction was

effected by Sir Joseph Hooker, 70 years ago, when he was

attached to the famous expedition under Sir James Ross

in the “ Erebus” and “ Terror ”-——it never appears to have

become permanently established in this country. A goodly

number of fine examples of its natural companion, J. betu-

loides, may be met with in the milder parts of the British

Isles, but of NV. antarctica itself there are few. Indeed, if

we except the young trees raised from seed brought from

Chili by Mr. H. J. Elwes in 1902, there is but one well-

known specimen ; this grows at Hafodunos in Denbighshire,

and is balieved to be over 30 years old. From this it

would seem as if the species is not altogether adapted to

our climate. Yet the young trees in the collection at Kew

are growing with remarkable vigour, and passed through

the trying winter of 1908-9 without injury.

According to Mr. Elwes, N. antarctica is the commonest

Species met with by him, during his South American

journey, at high elevations on both sides of the Chili-

Argentine frontier. He found it associated with Araucaria

at 4,000 ft. above sea-level, and it occurs frequently in

marshy situations on the plain of Valdivia. The variety

here figured is known in Chili as “Mere.” It forms a

dense scrub on the Argentine side of the frontier; near the

Baths of Chillian it goes up to 7,000 ft. or even higher,

and covers the summits of the mountains round Lake

Nahuel-huapi up to 6,000 ft. When seen here by Mr.

Elwes in the month of February the leaves had turned a

brilliant red. This variety was again met with by the

Princeton University Expedition growing in Patagonian

Swamps and in woods at Chubut in the Argentine Andes.

The individual which supplied the material on which our

figure is based was raised from seed collected by Mr. Elwes —

near Lake Meliquina. It is now a small tree, 16 ft. high;

it flowered very freely in a clump of heaths near the

Pagoda at Kew in May, 1909, The plants at Kew are

grown in various soils; those in the average sandy loam

with which a little peat has been mixed thrive best. Our

young trees are of rather thin, open habit, making, at present,

annual shoots 1-3 ft. in length. Their distichous mode of

branching adds to the peculiar elegance and distinctiveness

of their appearance. Propagation is readily effected by

means of layers, but it is doubtful whether trees so raised

will make such well-grown specimens as those obtained

from seed,

Cornus florida, according to Sargent, is one of the

commonest and most generally distributed of deciduous

trees and shrubs in the Middle and Southern United States,

and occurs at all elevations from sea-level to nearly the

summits of the higher Alleghany Mountains. The type,

figured in 1801, at t. 526 of this work, has been in England

nearly 200 years. It was in the nursery of Thos. Fairchild

at Hoxton in 1730; nine years later it was in the Chelsea

Botanic Garden. The variety figured, which is rare in a

wild state, was first introduced by Messrs. Parsons, of

Flushing, New York. The material for our figure was

supplied by Mr. B. E. C. Chambers, from his garden at

Grayswood Hill, Haslemere, which contains a remarkable

assemblage of rare trees and shrubs, admirably cultivated.

May, 1910.

The only other cultivated Cornels with which C. florida is —

likely to be confused are C. Nuttallii, Audub., figured at

plate 8311 of this work, and the Japanese C. Kousa, Buerg.

The former is distinguished by the flower-heads not being

enclosed by the involucre during winter, and by the usually

more numerous bracts with acute, but not deflexed, apices.

C. Kousa differs from both in its smaller ovate-lanceolate,

acuminate bracts, and in its smaller leaves.

The bark of C. florida, officinally known as “ Dogwood

Bark,” yields cornine, a bitter principle which has astringent,

tonic and stimulative properties. It was at one time valued,

especially in America, in intermittent fevers.

Cornus florida is unlikely to occupy an important place

in English gardens, except, perhaps, in the more favoured

‘ones of the south and west. In Ireland, South Wales and

in the west of Scotland it ought to succeed in many places;

and in those favoured regions few more beautiful shrubs can

be grown. At Kew it succeeds only under protection.

Mr. Chambers informs us that his plant of var. rubra is now

10 ft. high and 84 ft. through, and that it is much more

floriferous and lasts a longer time than the ordinary white-

“flowered” type. It is grown in open sandy loam fully

exposed to the sun.

_Description.— Tree, of bushy habit, occasionally 40 ft.

high in a wild state, usually a wide-spreading bush Jess than

The Acanthopanax here figured was first discovered in

Hupeh, Central China, by Mr. A. Henry, and was intro-

duced to cultivation by Messrs. J. Veitch & Sons through

their collector, Mr. E. H. Wilson. From one of the plants

raised by Messrs. Veitch in their nursery at Coombe Wood

and obtained from them for the Kew collection in 1905,

May, 1910.

the material for our illustration has been taken. This

plant is now 5 ft. high and as much through, with stout,

straight thorny branches and of sturdy rather than graceful

habit. As a shrub for gardens it is, on the whole, more

curious than beautiful; at the same time, the foliage is

handsome and the globose heads of inky black fruits are

striking. The leaflets are variable as regards shape and

degree of pubescence. The flowers are not particularly

attractive ; they do not appear, as a rule, until August and

September. The fruits ripen in October and continue

until Christmas. The plant succeeds well in ordinary

loamy soil and may safely be deemed hardy. The bark

of the root is employed in China as a drug.

Desoriprion.—Shrub, 5 ft. or more in height, branches

soon becoming glabrous, armed with flattened, abruptly

conical often recurved thorns with longitudinally expanded

bases. Leaves 5-, rarely 3-foliolate ; petiole 13-2 in. long,

at first more or less puberulous, soon becoming glabrous

except near the tip; leaflets oblanceolate or wide lanceolate-

ovate, acute or shortly acuminate, often narrowed at the

base into a petiolule 2-3 lin. long, entire or often from the

middle onwards closely finely serrate, occasionally more

conspicuously toothed, the central 14-5 in. long, I-14,

rarely 13 in. wide, deep green and scaberulous above, paler

and more or less pubescent especially in the nerves beneath ;

lateral nerves about 7 on each side. Umbels clustered at

the ends of the branches, the terminal much larger than the

others, many-flowered, dense, $—24 in. across; peduncles

stout, almost glabrous or pubescent or somewhat tomentose,

1-1} in. long ; pedicels in flower 4-6 lin. long, with the

same degree of pubescence as their peduncles, never articu-.

late. Ovary glabrous or more or less pubescent, obovoid,

in flower 3-1} lin. long; disk 3-11 lin. across. Petals

almost or quite as long as the ovary. Styles of the fertile

flowers 2-1 lin. long or slightly longer, connate; stigmas

minute. Berry black, globose, 4-5 lin. in diameter.

striking and delightful object. It is not certainly known

whether its original home be Central America or Mexico,

but it almost certainly came from one or other of these

areas, and Mr. Vicenzo Ricasoli, in the place quoted above,

gives Mexico as its home. It appears to have been intro-

duced to Italy in the first instance by Mr. Francesco

Franzosini, in whose fine garden at Intra on Lago Maggiore

there were plants prior to 1878, the year in which it was

added by the late Sir T. Hanbury to his collection at La

Mortola, where it flowered for the first time in 1889. Since

then it has flowered repeatedly there, has always produced

abundant seed, and has been widely distributed. It was

first added to the collection of Agaves at Kew in 1890, when

Sir T. Hanbury sent seeds to this establishment, which in

1892 was further indebted to the same generous correspon-

dent for a living plant.

The plant from which the material employed in preparing

our plate was obtained was a magnificent specimen in the

garden at La Mortola, whose age was not much over 15 years.

At the end of April it showed no sign of flowering, but in the

middle of May the enormons peduncle began to appear, and,

growing with great rapidity, reached its full size in about

six weeks; the first flowers began to open on the lowest

branches on July 21st, and a fortnight later the material for

our plate was available,

A, Franzosini is easily propagated by suckers which soon

grow into sturdy plants under the treatment suitable for

A. Vera Cruz, and appears to be as hardy as that species.

At La Mortola it seems to prefer the hottest situations ; it

requires as much light as possible, and should not be kept at

all damp, otherwise it is apt to become less glaucous and to

lose much of its distinctive beauty. At Kew A. Franzosum

The genus Fouguieria, established in 1823 by Bonpland

and Kunth, was five years later treated by the elder

De Candolle as the type of a distinct natural family. In

taking this step, De Candolle in reality only endorsed a view

already suggested by the authors of the genus. Since then

the affinities and the systematic status of Mouguieria have

been carefully studied by several able taxonomists, whose

conclusions have not always been in accord. One _ point

which emerges from the discussion as indisputable is that the

genus occupies a singularly isolated position. Having

regard to this fact, and to the consideration that its relation-

ships are by no means clear, it is more satisfactory to treat

Fouquieria as the representative of an independent family.

Jong, 1910

The species here figured, 7. splendens, extends westwards

from N.W. Texas through New Mexico and Arizona to

Southern California, thence sonthwards to Lower California

and the Mexican states of Coahuila, Chihuahua and Sonora.

In the northern part of this area the plant_is variously

known as the Coach Whip, the Vine Cactus, Jacob's Staff;

its Mexican name is the Ocotello. The bark contains a

gum and a resin, and yields, in addition, the substance

known as Ocotello Wax. It makes an effective and almost

impenetrable hedge, and, according to Dewey, it is some-

times planted closely in line around a rectangle 10 ft. long

and 5 across; an opening is left at one end, a covering

of brush is laid on top, and the result is a hut such us

Mexican families of the poorest class inhabit.

The material from which our figure has been prepared

was communicated by Mr. F. W. Moore from a specimen in

the Glasnevin collection. That plant is about 3 ft. in

height, sparingly branched and strongly armed with stout

thorns, The few roots are strong and woody ; the small,

thin and delicate leaves are deciduous; the indication there-

fore is that the plant does not require much water or 4

moist atmosphere. It thrives well and is vigorous at

Glasnevin in the Cactus house, in partial shade, with a

minimum night temperature of 50°-52° F.; it is grown in

an 8-in. pot in loam, mixed with one-fifth finely broken pot-

sherds and old mortar. In the growing season, March to

October, it requires a fair amount of water, and has

occasionally to be syringed ; during the dull winter months

it needs very little water, and the atmosphere has to be

kept dry so as to provide the marked period of rest which

the plant demands,

Descriprion.—Shrub, in a wild state 6-20 ft. high,

sparingly branched from the base, branches up to 1 in. thick,

nearly straight, armed with spines, channelled and covered

with smooth, at first tawny, at length ash-grey bark.

Leaves of the long branches obovate- or oblanceolate-oblong;

obtuse or subacute, narrowed at the base to a very short

Ser #-1f in. long, 3-5 lin. wide; those of the short

ranchlets fascicled and smaller, their petioles and midribs

ultimately hardening into long spreading persistent spines

3—l in. long. Inflorescences usually terminal, casually one

or more axillary, panicled, narrow, 4-6 in. long, generally

many-flowered, on the short branches often reduced to

fascicles of flowers, or sometimes almost all to single flowers ;

bracts scarious, caducous; longest pedicels 2-3 lin. long,

often quite short. Sepals wide ovate or nearly orbicular,

obtuse, 24-4 lin. long, pale with hyaline margin. Corolla

red; tube straight, slightly widened upwards, 5-8 lin. long ;

lobes wide ovate or nearly orbicular, obtuse, recurved or

revolute, 2-23 lin. long. Stamens 15, filaments exserted,

unequal, slightly widened above the base and bearing there

on the inner aspect a 2-lobed scale which is hirsute on the

outer side; anthers 2 lin. long; connective apiculate.

Styles more or less connate from below upwards. Capsule

5-9 lin. long, valves crustaceous. Seeds 34-4 lin. long,

white, surrounded by a wing | lin. wide at the base, which

soon breaks up into a fringe of hairs.

The beautiful shrub here figured was originally discovered

in South Carolina by Michaux prior to 1803, and was again

met with by Nuttall in the same region, in swamps between

Camden and Statesville, some time before 1818. Nuttall

found it also near Newbern in North Carolina, but this very

rare plant, which seems to be confined to Carolina, appears

never to have been gathered, after Nuttall’s time, until

Mr. W. W. Ashe, of the State Geological Survey, met with

it in a pine-barren swamp between the Cape Fear and Back

rivers, some ten miles to the north-west of Whitehall in

North Carolina, during the winter of 1893-94. In the

summer of 1894 it was introduced, from this locality, into

the collection of Mr. G. W. Vanderbilt at Baltimore, where

it flowered in June, 1905. Since then this Ka/mia has been

collected in swamps in Bladen county, North Carolina.

The plant from which the figure of A. cuneata now given

June, 1910,

has been prepared is one of a large batch raised from seed

presented to Kew, in January, 1904, by Professor Sargent of

the Arnold Arboretum, The species, so far as can be judged

from the experience of the past five winters, promises to be

quite hardy. It has an erect habit, and flowers in July

from the upper portion of the preceding year’s growth. At

Kew it grows very well in the soil used for Ericaceous

plants generally ; a sandy loam, devoid of calcareous matter,

to which a proportion of peat has been added. Grown ina

mass, K. cuneata produces a very pleasing effect; it is,

moreover, useful on account of its flowering so late in the

season, when comparatively few shrubs remain in blossom.

Description. — Shrub, 3-4 ft. high, young branches

glandular-hairy and red, ultimately glabrous and dark

brown. Leaves alternate, 3-2 in. long, }-} in. wide,

Scutellaria violacea, the species now figured, has been in

cultivation at Kew since 1900, when plants were raised

from seeds received from the Botanic Garden at Hakgala,

Ceylon. The nearest allies in the genus are S. discolor, Colebr.,

also an Indian species, and S. indica, Linn., which, in spite

of its name, is a Chinese plant. The former is, as a rule,

readily distinguished from S. violacea by the fact that its

flowers are almost always scattered on the rachis, whereas

in all the forms referred to S. violacea they are opposite.

The latter, which agrees with S. violacea in having opposite

flowers, appears to be always smaller in stature, in leaves

and in flowers. In the wide sense in which S. vivlucea is

taken in the Flora of British India the species extends from

June, 1910,

the Nilgiri Hills in the Indian Peninsula, at elevations up to

7000 ft., southwards to Ceylon, and is represented in the

Eastern Himalaya by a distinct variety. Even in its

southern area, however, the variability in stature, in the

hairiness and texture of the leaves, and in the size of the

flowers is such that Sir Joseph Hooker recognises there

three other varieties, all of which have at times been treated

as distinct species. The form here depicted, which appears

to be typical S. violacea, as cultivated at Kew, forms a fairly

compact plant about a foot and a half in height, which

flowers freely in a warm house about midsummer. As a

pot plant it is most satisfactory when raised from cuttings

every year, and when grown under the conditions suitable

A native of the mountains of Java, to which island it

appears to be confined, this distinct species, which was dis-

covered by Teijsmann and Binnendijk, and described by

them more than half a century ago, long remained prac-

tically unknown in Europe, and has but recently been intro-

duced to cultivation. The plant from which the figure now

given has been prepared was presented to Kew in 1908 by

the Hon. W. Rothschild, Tring, and flowered in the tropical

orchid collection in June, 1909. C. biflorum is, perhaps,

most nearly allied to C. picturatum, Lodd. (Bulbophyllum

icturatum, Reichb. f.), a native of Tenasserim, figured at

t. 6802 of this work, but is very easily distinguished by the

characters noted by Mr. Rolfe. The most striking feature

in our plant is the constantly 2-flowered scape, to which it

owes its name, and on account of which it serves as a link

between the group of forms with solitary flowers, referred io

at t. 8199, and those species that possess the umbellate

inflorescence at one time thought characteristic of the

genus, The difficult question as to whether the genus Cirrho-

June, 1910.

petalum, proposed by Lindley, can be upheld, is one that has

already been alluded to in these pages. ‘lhe other leading

feature in a normal Cirrhopetalum is the elongation of the

Jateral sepals, which, moreover, are perfectly united. This

character, like that of an umbellate inflorescence, also

breaks down, for species occur that serve to link forms like

the present, in which the elongation is pronounced, with

typical Bulbophylla, where the lateral sepals hardly exceed

the upper. But the difficulty thus created is only a tech-

nical one. It no doubt fully justifies the union of Cirrho-

petalum and Bulbophyllum, if the question be considered from

a purely formal standpoint. When, however, regard is had to

the fact that such intermediate forms are few in number, and

to the consideration that if these be left out of account it 1s

impossible to mistake a Cirrhopetalum for a Bulbophyllum,

it is more convenient to adopt, as Mr. Smith in this case has

done, the usage that prevails among growers of orchids

generally. C. biflorum thrives well at Kew planted in a

teak basket in sphagnum moss and osmunda fibre; it

requires to be kept in a moist condition during the period

of active growth.

Description.—Herb, epiphytic. Rhizome creeping, rather

slender. Pseudobulbs somewhat distant, ovate-oblong, tetra-

gonous, about 14-14 in. long, monophyllous. Leaves sub-

sessile, lanceolate or oblong-lanceolate, somewhat obtuse,

coriaceous, narrowed to the base, 5-6 in. long, 3-2 in. wide.

NOTICE OF RE-ISSUE.

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

very difficuls 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 me-t 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 BorayicaAL Magazine, commenced in 1787, and continued

with uninterruptel regularity to the present time, forms the most

extensive and authentic repertory of Plant History and Portraiture

extant. Tne Txtrp Series, 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 commenc2ment in 1787, including the First,

S:cond, and Third Series, to the end of 1904, 130 vols., may be had,

The handsome Begonia which forms the subject of our

plate is perhaps best considered a garden race of JB.

Martiana, Link and Otto, a native of Mexico, which the late

Mr. A. de Candolle considered to be itself no more than a

variety of B. gracilis, Kunth, The examination of a large

series of specimens, however, has led Mr. Rolfe to take the

view that the two are, on the whole, better treated as

distinct species; B. gracilis is always a smaller plant than

normal B. Martiana, with more slender and never strictly

erect stems, while it has much more divided leaves and a

different inflorescence. As thus separated B. Martiana is

represented in gardens by three more or less readily dis-

tinguishable forms, known respectively as var. grandiflora,

var, puleherrima and var. racemiflora. They differ but

slightly from each other and have all been familiar plants

in Begonia collections during the past twenty years. All

three are good garden plants, with stems sometimes reach-

ing 2 ft. in height when well grown, though when they

Jury, 1910.

are small in size and weak in growth owing to having

received unsuitable treatment, they are alike in bearing a

close resemblance to B. gracilis, with which, as already

remarked, their identity has been suggested. Of the three

forms, that now figured from a plant which flowered in the

Kew collection in July, 1909, is certainly the finest, and the

extent to which selection has led, in this case, to the evolu-

tion of an improved garden race may perhaps be best

estimated by a comparison of our illustration with that given,

at plate 2966 of this work, of B. diversifolia, Graham, which

is now recognised as being only a state of B. Martiana.

Our plant grows well when kept in a frame or greenhouse

and shaded from bright sunshine. The whitish, irregularly

shaped tubers lie dormant from about October until the

following April, when they develop several stems which

grow rapidly and flower freely in July. The plants ripen

seeds and also produce clusters of small bulbil-like buds—

which may be used for propagation in place of seeds, in the

axils of the leaves.

Descriprion.—Herb; terrestrial; tuber ellipsoid-oblong,

fleshy, about 2 in. long; stem 1-14 ft. high; branches erect,

fleshy, glabrous, leafy. Leaves petioled, obliquely cordate,

somewhat acute, twice crenate, glabrous or sparingly hairy,

This handsome Iris was met with for the first time in

1848 by Sir J. D. Hooker, who found it on Tonglo as well

as on the Yakla in Sikkim at about 10,000 ft. above sea-

level, and made in the field a coloured sketch of the plant

which is now in the Kew collection. It was again gathered

on Tonglo in 1857 by the late Dr. T. Thomson, in 1868 by

the late Dr. I. Anderson, and in 1875 by the late Mr. C. B.

Clarke, to whom the species was dedicated by Mr. Baker.

It has since been met with in other localities in Sikkim

and has been gathered in the Chumbi Vailey, further to the

east, by the collectors of the late Sir George King, to whom

European Iris lovers owe its presence in their collections,

where it has found a welcome since 1876. ‘Treated origin-

ally, for reasons which have been explained by Mr. Dykes,

Juxy, 1910.

from whose garden at Godalming came the material on

which our illustration has been based, as a member of the

Pseudevansia group, it now appears that its true position in

the genus is near the Western Chinese J, Delavayi, Mich.,

in the Apogon group. Its cultivation offers no especial

difficulty and its propagation is easy. Mr. Dykes has called

attention to the peculiar liability of this species to consider-

able variation in the form and coloration of the standards,

and to some variation in the foliage. In imported plants

he finds that all the leaves have a curiously polished upper

surface, whereas in some seedlings there may be found

leaves that are distinctly glaucous on both surfaces, while

other shoots on the same plants bear leaves which show the

characteristic polished upper surface.

_Descriprion.—Herb ; in cultivation sometimes nearly 3 ft.

Few shrubs are more satisfactory in the garden than the

members of the genus Philadelphus. They are easily grown

and they flower profusely at a time when the great majority

of flowering trees and shrubs have gone out of blossom.

The one now figured is attractive not only for its abundant

clusters of white, well-formed flowers, but for its agreeable

fragrance. P. Delavayi was first introduced into European

gardens by the Abbé Delavay, who sent seeds from Yunnan in

1890. It was again met with in 1904 by Mr. E. H. Wilson,

from whose seeds the plant here figured was raised by Messrs.

J. Veitch & Sons. Though a distinct and easily recognis-

able form, it seems somewhat doubtful whether it should be

considered specifically separable from the Indian P. tomen-

tusus, Wall., for the salient differences are only to be found

in the greater degree of tomentum on the upper surface of

Juny, 1910.

the leaves and the considerably smaller fruit of this, the

Chinese representative of Wallich’s plant. Like the rest of

the genus, P. Delavayi thrives in rich moist soil in full sun,

and is easily increased by cuttings of soft wood placed in

heat. The only pruning necessary is an occasional thinning

out of worn out or overcrowding stems; no shortening back

can be effected except at the expense of the succeeding crop

of blossom,

Descriprion. — Shrub; 3-15 ft. high; branches nearly

cylindric, bark flaking; sterile twigs sparingly hairy,

The Aristolochia here figured was first discovered by

Pere David in the Moupine region in Western China. Latel

it was met with at T'sekou in Yunnan by Pere Monbeig

and was again collected, at an elevation of 6,500 {

above sea level in Western China, by Mr. E. H. Wilson

behalf of Messrs. J. Veitch & Sons, in whose nurseries

Coombe Wood it flowered in June 1908 and again in Ju

1909. A. moupinensis is very closely allied to A. Kaempferi,

Willd., a species figured at t. 49 of Kaempfer’s Icones

Selectae, edited in 1791 by Sir Joseph Banks, under the

name San Kakso. This figure shows the trilobed leaves

and the naked peduncle described by Willdenow and

evidenced by a Japanese specimen collected by the late Mr.

Maximowicz. But another Japanese specimen at Kew

collected by Mr. F. V. Dickins and identified by the late Mr.

Franchet as A. Kaempferi, though it has the naked peduncle

of that species, has entire leaves as in A. moupinensis, and

it may be that eventually the two plants will have to be

Jury, 1910.

considered conspecific. The peduncle of A. moupinensis is

however distinctly longer than that of A. Kaemp/eri and

the perianth, although hairy, is less densely so. The

material from which our illustration has been prepared was

communicated by Messrs. Veitch, who kindly supply the

information that the plant has proved quite hardy at

Coombe Wood. It flowers there very freely, prefers a

rather retentive loamy soil and grows best in a sunny

position ; no pruning is required beyond the removal of any

weak or decayed wood, In its native habitat, according

to Pere David, it is found growing among shrubs.

Description.— Undershrub; scandent withslender branches

which at first are densely silky, but when older are merely

puberulous. Leaves cordate, acute or shortly acuminate,

4-43 in. long, 24-4 in. wide, with rounded but hardly

meeting auriculate basal lobes, impressed punctate and beset

with short hairs above, greyish pubescent beneath ; petiole

24 in. long, hirsute. Peduncles axillary, solitary, 1-flowered,

about 3 in. long; bracts upraised, ovate, 5 lin, long.

Perianth-tube pale green outside, 14 in. long, abruptly

curved, swollen in the middle, narrowed both to the base

and the apex, hirsute without, yellow within; limb

obliquely 3-lobed, 14 in. across, its margin recurved

between the lobes, yellowish with red markings inside,

greenish towards the margin. Column 2 lin. long; anthers

HEMSLEY.

The pretty little Rhododendron which is here figured

is one of the many novelties for the introduction of which

horticulture has to thank Messrs. J. Veitch & Sons, who

raised plants from seeds secured on their behalf in Western

China by Mr. E. H. Wilson. Some of these plants flowered

with Messrs. Veitch in their nursery at Coombe Wood in

_ April 1909, when the material from which our illustration

has been prepared was communicated. It happens that this

is one of the few species obtained by Mr. Wilson, whereof

there are no specimens in the herbarium collection at Kew

that correspond with the field-number accompanying the

.seeds, so that nothing is yet known as to the appearance of

the fruit. The plants themselves grow well at Coombe

Wood in the open ground and without artificial protection,

under the conditions suitable to most other species of the

genus. When the earliest flowering shoots produced in

this country became available they appeared to justify the

Jozy, 1910.

segregation of the plant from 2. flavidum in consequence of

various differences in floral characters. Well developed

specimens, subsequently communicated, have, however,

satisfied Mr. Hemsley that the characters in question are

insufficient, and prove that the form of the calyx-lobes, the

length of the corolla-tube and the relative length of the

stamens and corolla are by no means constant. A. flavidum

will be welcomed in gardens as an addition to the scanty

group of species with yellow flowers.

Descriprion.—Shrublet ; 14-2 ft. high, densely branched,

the twigs slender, covered in almost every part save the

corolla with fine scales. Leaves closely set, overlapping,

coriaceous, persistent ; blade ovate-oblong, 5-10 lin, long,

suddenly apiculate, the base rounded, concavo-convex with

recurved margins, closely scaly on both surfaces, dark

green above, polished where not covered with scales and

channelied along the midrib, beneath paler; petiole 1-14 lin.

long. Flowers yellow, 3-5 together at the tips of the twigs,

with abruptly recurved pedicels 2-34 lin. long. Calyz

almost 2-labiate, herbaceous; lobes somewhat unequal,

ovate, 2-3 lin. long, sharply acuminate, at length reflexed.

Corolla almost regular, nearly rotate, about 1; in. wide,

without scales, lobes rounded with wavy margins, throat

somewhat pubescent. Stamens 10, shorter than the corolla,

filaments thickened a little above the base and below the

middle, somewhat pubescent. Ovary 5-celled, very closely

scaly; style and ovary together 8-9 lin. long, the style

puberulous below the middle. Capsule not seen.

The striking Bulbophyllum which forms the subject of

our illustration is a member of a very distinct group of

Malayan species which includes B, Pahudii, Reichb. f.,

B. Eriessoni, Kraenzl., figured at t. 8,088 and B. Bin-

nendijkii, J. J. Sm., figured at t. 8,187 of this work.

From the last-mentioned species, which is its nearest ally,

our plant differs in a few minor structural details and in

having flowers without spots. B. virescens was_ first

described ten years ago from specimens collected on Mount

Tuna in the island of Amboina, at about 2,500 feet above

sea level. Shortly thereafter plants which, on flowering,

proved to belong to this species were obtained by Messrs.

Hugh Low & Co. from an island off the coast of New

Guinea. ,The plant from which our figure has been

made was acquired by purchase from Messrs. Low in 1905 ;

it flowered in the tropical Orchid house at Kew in June,

Aueust, 1910.

1909, and was as remarkable in appearance as it was

disagreeable in odour. It requires the same cultural treat-

ment as its near allies, B. Hricssoni and B. Binnendijkii;

a shallow teak basket, a compost of sphagnum, peat fibre

and dead leaves, with a position close to the roof glass in a

moist tropical house. When the plant is making new

growth plenty of water should be supplied; when growth

has finished only enough water should be given to prevent

the soil from becoming quite dry.

Description.—Jlerb, epiphytic ; rhizome creeping, stout,

clothed with striate imbricating sheaths; pseudobulbs

remote, linear-oblong, striate, 4-5 in. long, 1-leaved, clothed

at the base with ovate striate sheaths. Leaves petioled,

. The plant here figured, which was raised at Kew from

seed received from the Tokyo Botanic Garden, quite merits

the encomium “ decus generis,” bestowed upon it by the late

Mr. Maximowicz when he for the first time published it

under its proper genus. Its nearest ally is Patrinia gibbosa,

Maxim., like the subject of our illustration a native of Japan ;

both are members of the section Centrotrinia, founded by

Maximowicz to include those species in which the corolla is

gibbous or spurred and the fruit is adnate to an accrescent

bract. P. triloba is, however, readily distinguished from

P. gibbosa by its larger flowers, its rather smaller, sharply

lobed and cordate leaves and its leafy stem. Siebold was

the first European botanist to meet with P. triloba, which is

Avaeust, 1910.

confined to the woodland tracts of Central and Northern

Japan; his specimens formed the basis of Valeriana triloba,

Miq. It was again met with by Maximowicz, whose speci-

mens were distributed as Patrinia palmatijida, a name

modified in 1867, when the species was formally published,

to P. palmata. The study of the specimens issued by

Maximowicz had meantime satisfied Miquel that the plants

collected by Siebold and by Maximowicz are conspecific

and that the generic position accorded to the species by

Maximowicz is correct. The adjustment of name thereby

rendered necessary was made by Miquel in 1870 and

endorsed by Maximowiez a year later. P. triloba is a

hardy herbaceous perennial, easily cultivated under the

conditions suitable for most of the species of Patrinia and

Valeriana. It thrives well in the Rock Garden at Kew,

where it is in flower in July and August, the months

during which it also flowers in a wild state.

Descriprion.— Herb, perennial; stems erect, terete,

reddish, 8-16 in. high, unbranched below the inflorescence,

with lines of pubescence on the peduncles and with pubescent

nodes. Leaves petioled, the radical cordate, those of the stem

ovate-cordate, deeply palmately 3- or 5-lobed, and usually

d-nerved from the base, the largest 3 in. long, 2 in. wide;

basal lobes rather smaller than the rhomboid more or less

prominent; margin rather coarsely toothed except towards

the tips of the lobes ; sparingly hairy above, more markedly

pubescent on the margins and along the nerves beneath;

petioles slender 34 in. long, stem-clasping at the base.

Cymes 3-nate ; lower bracts leafy, ovate-lanceolate, 3-lobed,

The genus Pterostyraz, to which the subject of our plate

belongs, is so nearly allied to Halesia, Linn., and so similar

to that genus in floral characters, that in the Genera Plan-

‘ttarum the two were united by Bentham and Hooker. But

the position of the inflorescence, the absence of broad wings

on the fruit, the shape of the corolla and the difference

in number of corolla lobes so markedly distinguish Ptero-

styraz and Halesia that the two are now, by almost universal

‘consent, kept apart. The two groups inhabit different areas,

for while Halesia is an American genus, Pterostyrax is

Aveust, 1910.

confined to the old world, being represented by three

species in Japan and by two in China. Specimens of one

of the Chinese species have indeed at times been referred

to the species here depicted; this identification, it is now

found, cannot be sustained. One of the most distinct and

beautiful of hardy trees, P. hispidum grows well at Kew,

and flowers freely almost every year. When its branches

are furnished with their long pendent panicles, an example

of P. hispidum is one of the most effective ornaments of the

garden, the more so because, flowering as it does in late

June, it escapes comparison with other trees, equally

striking, which by then are out of flower. It thrives ina

good loamy soil and in a sunny situation and, like most

trees of its class, flowers most abundantly after a hot

autumn. It hasj never suffered in the least from frost at

Kew, but it grows to a larger size and more quickly in the

warmer counties, and the material from which our plate

has been prepared was derived from a particularly hand-

some specimen in the garden of Canon Ellacombe at Bitton,

near Bristol. In the south-west of Ireland there are some

splendid examples approaching 40 feet in height and more in

diameter of crown. The species should be raised from seed

which occasionally ripens in this country and has been

offered several times in recent years for exchange in the

Kew seed-list. Japanese nurserymen also offer it at

moderate rates, but usually under the name of its nearest

ally, P. corymbosum. The variable character of the under-

side of the leaves is not due to age, for leaves that are

finely white tomentose and leaves that are glabrous beneath

may be found on the same branch.

DEscRIPTION.— Tree, with glabrous branches and ashy-

brown bark. Leaves alternate, denticulate 24-8 in. long,

The plant now figured was received at Kew from tlhe

Singapore Botanic Gardens in 1905 with the suggestion

that it might be a form of Piptospatha Ridleyi, N. E. Br.,

figured at t. 7410 of this work; another species of the same

genus, P. insignis, N. E. Br., is given at t. 6598. The two

genera are indeed so closely allied as to be indistinguishable

so far as any vegetative character is concerned. They are,

however, readily discriminated when in flower because in

Piptospatha the connective is produced and the ovaries are

distinct, whereas in Gamogyne, the genus to which our

plant belongs, the anthers are truncate and the ovaries are

united. The plant figured has been grown on a small

rockery in the Nepenthes house, where it has thriven well

and has formed a sturdy tuft of leaves; it flowered for the

first time in March, 1909, and thus enabled its generic

position to be ascertained. As a garden plant Gamogyne

pulchra is superior to either of the species of Piptospatha

mentioned above, and in this respect is even preferable to

its nearest ally, Gamogyne Burlidgei, N. E. Br., a Bornean

Aveusr, 1910,

plant which is well known in tropical collections. The

botanical characters that distinguish G. pulehra from

G. Burbidgei, it will be observed, are not very striking ;

the species now figured is provided with neuter organs at

the base of the spadix where in G. Burbidge: there are

none; on the other hand, G. Burbidgei has neuter organs

situated between the male and female portions of the

spadix, a situation in which there are no neuter organs in

G. pulchra. The stigmas of G. pulchra are red, whereas

in G. Burbidgei they are greenish yellow, but the most

marked distinction between the two plants, from the cultural

standpoint, lies in the colour of the spathe which in

G. pulchra is much deeper and brighter red than in G. Bur-

bidgei. The localities from which the two species have

been reported are somewhat remote; G. pulchra comes from

the Malayan Peninsula, and has not, so far, been met with

in Borneo. Mr. H. N. Ridley has kindly informed us that

G. pulehra comes from the rocky stream on Gunong Pulai

in Johor. Gunong Pulai is the most eastern peak in the

range of which Gunong Panti, the original habitat of

Piptospatha Ridleyi, is the most western hill.

The plant here figured has long been grown in gardens

under the name of Psoralea pinnata, itself an old garden

plant which is stated in the Hortus Kewensis to have been

in cultivation at Hampton Court so long ago as 1690.

When Ericas and other South African shrubs were more in

favour than they are at present, P. pinnata was a favourite

greenhouse plant, and it is by no means improbable that

then, as now, the two forms were in cultivation without

being distinguished from each other. The right of the

form here figured to separate recognition was pointed out

by Ecklon and Zeyher more than seventy years ago, and

although the late Dr. Harvey was led to treat P. pinnata,

Avuaust, 1910.

somewhat comprehensively, as a species with four distinct

varieties of which our plant is one, Mr. Hutchinson points

out that the characters which distinguish the two are such

as to justify their segregation, not merely from the stand-

point of the cultivator, but from that of the taxonomist.

The peduncles of P. pinnata are exceedingly short, its

calyx-lobes are ovate-lanceolate, acute and subglabrous,

while the indumentum is much Jess dense than in P. affinis,

which has peduncles as long as the leaves, a strongly

10-ribbed calyx tube, and short, rounded, very densely

hirsute calyx lobes. The true P. pinnata is widely spread

in South Africa from the Cape Peninsula to Algoa Bay.

The plant here figured has a more restricted range and has

been met with only in the divisions of George, Knysna,

Uniondale and Uitenhage. In most parts of England

P. affinis can only be grown as a pot plant, when it may

be made to form bushes 3 feet or so in height, or planted

in the border of a sunny greenhouse, when it soon becomes

a large Cassia-like shrub reaching 10 feet high; at Kew

it flowers in early spring and forms a very attractive object

in the Conservatory and the Temperate House. The specimen

from which our plate has been prepared came, however,

from the garden of Mr. T. A. Dorrien Smith, resco Abbey,

Isles of Scilly, where the plant is quite hardy in the open

and flowers in April.

The species here figured is a native of the district of

Batoum to the south of the Caucasus, where the familiar

Rhododendron ponticum, Linn., figured at t. 650 of this

work, is also wild. It was discovered some twenty-five

years ago, by Baron Ungern-Sternberg, growing under

Picea orientalis at elevations of from 4000 to 6000 feet

above sea-level, where it occupies a zone between that of

f. ponticum, at lower levels, and that of A, caucasicum, Pall.,

figured at t. 1145 of this work, higher up. The subject of

our illustration was raised from seed received from the

Imperial Botanic Garden, St. Petersburg, in 1866; at Kew

it has been grown in a pot under the conditions most

SepremBer, 1910.

suitable for Himalayan species and is now a bush about

6 feet high, with leathery dark green leaves, smooth above

but densely woolly below. It has very rarely flowered ; the

flowers now figured were produced in July, 1909. Although

it has hitherto been afforded protection during winter there

is reason to think, when its native habitat and the

behaviour of other species from the same region are taken

into account, that it may prove hardy in this country.

Descriprion.— Shrub, or small tree, 12-20 feet high ;

flowering twigs straight and stout, at first pubescent.

sparingly clothed with crisp white hairs; bracts narrow,

acute, shorter than the pedicels, tawny, with a white

pubescence which soon disappears. Calyzx-lubes unequal,

13-3 lin. long, lanceolate, obtuse, glandular-ciliate. Corolla

widely campanulate, glabrous outside, within puberulous

below the middle, 5-lobed halfway down, the lobes almost

A. marked feature of the species of the natural family

Gesneraceae to which the plant here figured belongs is

their extremely limited distribution. This pleasing Chirita

appears to be no exception to this rule, for it has so far

only been met with on the limestone rocks of Lankawi

which are, it appears, particularly rich in Gesneraceous

plants; it is one of the many novelties met with by

Mr. C. Curtis, in the course of his botanical investigation

of this island, which lies off the coast of Kedah in the

Malay Peninsula. It was introduced to European _horti-

culture by Mr. H. N. Ridley, who communicated seeds to

Kew from tle Singapore Botanical Garden in 1905, the

year in which he first published an account of the plant.

As cultivated at Kew, in a moist tropical house, it is a

September, 1910.

bushy compact annual about 2 feet in height, which flowers

freely and continuously during autumn. It is easily

brought to perfection under the treatment suitable for

Gloxinias and other tropical Gesneraceae.

The plant here figured was raised at Kew from seeds

received in 1902 from the Botanic Garden, Singapore. Its

cultivation presents no difficulty and in the Palm House,

where it is grown, it forms a strong climber with pendent

shoots which in summer produce graceful terminal racemes

of yellow flowers. The filaments, which in bud are

yellowish, begin to assume a reddish tint when the petals

expand and by the time the anthers have fallen become

bright red and impart a characteristic appearance to the

flowers. One of the most widely distributed members of

the natural family Malpighiaceae, Tristellateia australis

appears to be characteristic of the littoral flora met with

on sea coasts from the Mascarenes to Melanesia. While,

Srrerember, 1910.

however, all save two of the nineteen species of Tvistellateia

hitherto described are natives of Madagascar or East Tropical

Africa, T. australis appears to occur only in the eastern

portion of this region; its most western habitats, so far as

is known, are the Malayan Peninsula and Siam, whence it

extends eastward through the Malayan Archipelago to

Queensland, New Guinea, New Ireland, the Solomon

Islands, New Caledonia, the Philippines and Formosa.

Description.— Shrub, climbing; twigs with prominent

lenticels, at first sparingly puberulous with centrally

attached hairs, at length glabrous; flowering shoots

pendulous. Leaves opposite, ovate or ovate-oblong, acute

and recurved at the apex, base usually rounded and some-

what folded, 2-4 in. long, 1-24 in. wide, dull, glabrous,

lateral nerves above rather pale, secondary nervation indis-

tinct, beneath closely reticulate with a rather prominent

midrib; lateral nerves arching, 4-5 on each side; petioles

4-3 in. long, markedly channelled, puberulous, with slightly

serrulate edges; stipules subulate, acute, slightly adnate.

Racemes 2-6 in. long, 12-16-flowered, the flowers opposite,

peduncled. Buds shortly cymbiform, concave behind,

5-ribbed ; peduncles 3-4 lin. long, with 2 small apical

subulate bracts ; pedicels 6-8 lin. long, thickened upwards.

Sepals small, erect, oblong, eglandular. Petals imbricate,

oblong or ovate-oblong, 5-6 lin. long, obtuse, base truncate

or subcordate, the claw 1 lin. long. Stamens 10, 2-seriate,

those opposite the petals the longer; filaments shortly

connate at the base, in bud yellow, soon becoming reddish

and ultimately, after the anthers fall, deep red; those

Opposite petals 2 lin. long, stout; those opposite sepals

The genus Micromeles is already represented in gardens

by two beautiful species, M. alnifolia, Koehne, and J.

Folgneri, C. K. Schneider ; the former of these has already

been figured at t. 7773 of this work. To these the species

now figured will prove a welcome addition. It was first

met with by Mr, A. Henry in North Wushan, Szechuen, in

1889, and was again collected by Mr. E. H. Wilson in the

same general region, in woods at 8000 feet above sea-level,

in 1904. From seeds sent by Wilson to Messrs. James

Veitch and Sons plants have been raised in their nursery at

Coombe Wood and from one of these, which flowered for

the first time in 1909, the material for our plate has been

derived. Jf. caloneura has proved perfectly hardy and has

thriven well in cultivation, and, while it is as yet premature

SepremBer, 1910,

to pronounce definitely with regard to its propagation, the

fact that it has fruited within five years of the sowing of

the seed seems to indicate that this should prove easy,

The graceful Asphodeline here figured, which is known

in Japan, where it is a native, as the Keibi-ran, or Keibi

“orchid,” has given some little trouble to students of

Japanese plants. The late Dr. Savatier, dealing with a

good Japanese figure of the species, at first thought that

it might be a Dianella but subsequently abandoned this

opinion in favour of that of the late Mr. Maximowicz who

treated it as an Anthericum; it is under the name Anthe-

ricum yedoense, bestowed on the plant by this eminent

botanist, that the plant is generally known in gardens.

Professor Matsumura, with ample reason, at a later date

removed the plant from Anthericum, but, as Mr, Makino

has more recently shown, Matsumura’s belief that our plant

Septremssr, 1910.

is a Bulbinella is not really more tenable than the sug¢es-

tion of Savatier or of Maximowicz, and there is hardly room

for doubt that the most satisfactory course is to adopt

Makino’s view and to consider it the type of a genus

apart. The flowers are dimorphic, each plant bearing one

kind only; in one group the stamens are twice as long as

the perianth; in the other the stamens are not exserted.

It is not improbable that this divergence may be of sexual

significance and it has been suggested that the long-staminate

form, here figured, may be the male. The plant from which

our plate has been prepared was presented to Kew in 1901

by Mr. A. K. Bulley, Ness, Neston, Cheshire. At Kew it does

not flower freely but is quite hardy, and forms, when in flower

in July, an elegant tuft. The treatment most suitable for it

is that which is also suitable for hardy species of Anthericum.

Descriprion.—/erb, perennial, with a short. thick root-

stock ; all parts glabrous. Leaves 6-11, tufted, distichous,

falcate-ensiform, obtuse or subacute, firm, smooth, 4-20 in.

The handsome Birch which forms the subject of our plate

is remarkable on account of its large and deeply cordate

leaves which impart to the species a striking resemblance to

some of the Lindens. It was originally met with by the

lamented Mr. Maximowicz in the island of Yezo in Japan, in

which country it was afterwards collected by Dr. Mayr on

the Nikko mountains in Hondo. According to Professor

Sargent it ranges northwards through Saghalien into

Manchuria. In 1888 the late Mr. J.-H. Veitch sent a

supply of seed of this tree from Yezo to England, thus for

the first time introducing it into Europe, where examples

are now to be met with in many establishments. In 1893

Professor Sargent presented to Kew from the Arnold

Arboretum a supply of seed received by him from the officers

of the Imperial Forest Department of Yezo. From a plant

Ocroper, 1910.

raised at Kew from this seed the material on which our

illustration is based was derived. 2B. Maximowiezii is a

member of the small section Betulaster in which are in-

cluded B. alnoides, Ham., B. luminifera, Winkler, and B.

Baeumkeri, Winkler, all natives of the Himalaya or of

Central and Southern China. The species included in this

section are characterised by having the elongated fruiting

catkins arranged in racemes, rarely solitary, and by their

broad-winged nutlets. The only other Birch in which the

leaves are distinctly cordate at the base is B. ulmifolia, Sieb.

& Zuce. ; from this B. Maximowiezii is easily distinguished

by its larger, broadly ovate leaves. Dr. Shirasawa describes

the wood of our tree as hard, and as showing no difference

in the colour of the heart and the sap woods. In Japan,

where it is known as Udai-kamba or Saihada-kamba, the

timber is used for house-building ; fishermen also make

torches of the bark, which is said to take fire readily even

when wet.

Descriprion.— Tree, sometimes attaining a height of

100 feet; trunk 13-34 feet thick; bark pale orange or grey,

papery; twigs nearly glabrous, with brown polished

sparingly lenticelled bark. Leaves broadly ovate, 3-6 10.

The strikingly beautiful Rose here figured is a native of

the mountains of Szechuan, between Mount Omi and

Tatienlu at elevations of from 7000-9000 feet above sea-

level. It was first collected by Mr. A. E. Pratt and was

subsequently met with by Mr. E. H. Wilson, who also

secured ripe seeds on behalf of Messrs. J. Veitch & Sons,

in whose nursery at Coombe Wood plants were raised which

are now 6-8 feet high. From one of the original plants

the flowers and fruits now depicted were supplied by Messrs,

Veitch in June and in September, 1909, It may be

remarked that in addition to the form here figured there is

another with paler flowers which, though also beautiful, is

less effective than that here shown. &, Moyesit will no

doubt require the conditions that have been found to suit

Ocroser, 1910,

the great majority of roses; a sunny position and a good

loamy soil inclining to be of a heavy rather than a hight

character. Such pruning as may be called for will have to

take the form of a thinning out of the older wood; certainly

not a general shortening back of the branches. It can be

propagated by cuttings made in August and placed in gentle

heat. Seeds will also be available, but having regard to the

possibility of hybridisation it will be necessary that any

seed collected be taken from plants isolated from other

roses.

Descrietion.— Shrub, 8-10 feet high; branches glabrous,

sparingly prickly, prickles short straight with widened

bases. Leaves with 7-13 leaflets, including the short petiole

3-7 in. long, 14-3 in. wide, rachis very slender, puberulous,

with also small prickles and minute glands; leaflets except

the terminal almost sessile, thin, ovate, oblong, elliptic or at

times almost orbicular, 4-11 in. long, gradually smaller

towards the basal pair, closely serrulate with thickened teeth,

glabrous on both sides except on the slightly pilose midrib

beneath, bright green above, paler beneath; stipules wide,

entire, 3-$ in. long, reddish, finely glandular-ciliate, the free

tips deltoid, subacute. Flowers deep blood-red, the petals

paler outside, 13-24 in. across, solitary or in pairs, erect;

peduncles shorter than the flowers, clothed with conspicu-

ous long-stalked glands. Calyx faintly tinged with dull

purple; tube naked or more or less clothed with stalked

glands; lobes 5, spreading, caudate from an ovate base,

leafy, almost as long as the petals, within tomentose, at first

also hairy outside on the portions overlapped in bud by

adjacent sepals, rarely slightly glandular. Petals usually 95,

almost orbicular, emarginate, 3-11 in. wide, explanate,

slightly overlapping. Stamens very many, filaments very

short, anthers tawny-yellow. Carpels 15-20, pilose, free,

somewhat exserted from the tube. Fruit deep orange-red,

ampulliform, crowned by the calyx lobes which become

erect and including these 21-913 in. long, sometimes

sparingly clothed with stalked glands below the middle 5

achenes somewhat pilose.

The Styraz here figured was discovered by Mr. A. Henry

in Szechuan and Hupeh in 1888, and again met with in

Szechuan by Mr. E. H. Wilson, who sent seeds to Messrs. J.

Veitch & Sons. From a plani raised from these seeds, now a

vigorous small tree of slender pyramidal form and about 9 feet

high, in the Coombe Wood Nursery, which flowered in June,

1909, the material for our figure was derived. The leaves are

of a pale bright green, and of striking size. Henry notes

this species as being, in a wild state, 30 feet high, with

white, fragrant flowers and remarkable white bark. It bears

a general resemblance in habit and flower to S. Obassia, Sieb.

& Zuce., a Japanese species sometimes met with in collections,

figured at t. 7039 of this work, but differs from that species in

Ocrozer, 1910.

that the bud is not enclosed by the base of the petiole, the

leaves are nearly always contracted at the base, more finely

toothed and glabrous or nearly so underneath, while the

inflorescence is branched at the base and the fruits are

abruptly contracted and mucronate at the tip. S. Hemsleyanus

is not closely related to any species from Eastern Asia; its

nearest ally appears to be the Mexican S. glabrescens, Benth.

Jt thrives well in open loamy soil and promises to be hardy ;

for yonng plants, a proportion of one-third peat added to

ordinary soil, about their roots, will probably be found

advantageous.

Drscriprion.— Tyee, reaching a height of 20-30 feet,

with remarkable white bark ; branches almost cylindric, at

first slightly stellate-hairy, at length glabrous and tawny.

The Iris here figured was discovered by Mr. E. H. Wilson

in Western China on behalf of Messrs. J. Veiteh & Sons,

and the material on which our figure is based was supplied

from a plant which flowered with them in July, 1909.

Another plant, presented by them to Kew, also flowered

simultaneously in the Iris collection, where it has grown

freely under the conditions suitable for the well-known

I. sibirica, Linn., which it resembles in habit. It appears

to be quite hardy, and promises to prove a useful addi-

tion to the list of garden Irises. In 1907 Mr. Wilson

redisvovered this plant in Western Hupeh, growing in grass-

lands near Fang Hsien, at about 7000 feet above sea-level.

But in addition to the form here figured there is another

and nearly related form, which flowered with Messrs. Veitch

in 1907, colleeted by Mr. Wilson on their behalf at Fang in

Central China, of more robust habit and with wider spathes

which extend as far as or beyond the top of the perianth-

OcrozrER, 1910.

tube, This stouter form has been distinguished by Mr.

Wright as a variety, var. major, of I. Wilsonii, but the

venation of the leaves is somewhat different, and it may be

necessary, when more ample material is available, to treat

this robust plant as a distinct species. As gathered in a

wild state and also under cultivation all the specimens of

Mr. Wilson’s two plants have pale yellow flowers. But it

has to be remarked that in 1906 Mr. G. Forrest collected,

on the eastern flank of the Tali range in Western Yunnan,

an Iris with bright purplish-blue flowers as in J. sibirica,

but which only differs from /, Wilsonii in other respects in

having more finely acute leaves and wider perhaps less

herbaceous spathes. This blue form is met with in moun-

tain pastures at 10,000 feet above sea-level.

Descriprion.—J/erb, rhizome short, its apex crowned

with the fibrous remains of the leaf-sheaths. Leaves at the

base 1-2 feet long, 3-4 lin. wide, the tip short, slightly

obliquely incurved, bright green, smooth, unequally veined

at least in the lower portion, 3-4 of the nerves towards the

centre more prominent than the others. Stem 8-12 in. high,

2- or 1-flowered, cylindric, 1-foliate, the leaf about 6 in.

long and arising below the middle, like the basal leaves

except as regards its size. Spathes somewhat herbaceous,

one usually produced in a short blade, 24-4 in. long, 1-2

lin, wide. Pedicels unequal, the longer reaching 5 in. in

length. Perianth-tube green, 4-5 lin. long, bluntly 3-

The Primula here figured was collected in Yunnan by

Mr. G. Forrest on behalf of Messrs. Bees, of Neston; the

plant depicted was acquired from that firm in August, 1909.

In Cheshire this species seems hardy, and plants grown in

the open at Kew were uninjured by the frosts of the past

winter. P. Littoniana belongs to a group of forms nearly

allied to one sent to Paris by the late Pere Delavay under

the name P. Viali. It is not clear what the relationship of

the different forms in this group may be. Mr. Franchet,

who formally described Delavay’s species, associated there-

with a plant found in Szechuan by Pere Soulie, which

has bilobulate corolla segments in place of the entire lobes

that characterise the plant named by Delavay. Messrs. Pax

and Knuth refer to P. Viali yet another Primula collected

by Mr. Ford in China. As regards the last-mentioned plant

it has to be remarked that, in the Kew collection, Ford has

included under the same field number two forms; one refer-

Octoser, 1910,

able to P. deflera, Duthie, but hardly distinguishable from

the plant figured by Pax and Knuth as P. Viali, the other

not distinguishable from the Eastern Himalayan P. bellidi-

folia, King. But Ford’s two plants, though distinguishable,

are so nearly related that his opinion, based on field obser-

vation, as to their specific identity may be correct; by

parity of reasoning there is nothing improbable in the views

of Pax and Knuth and of Franchet respectively, or in a

suggestion that all these forms may be referable to one

variable species first named P. bellidifolia by the late

Sir George King. This being so, it is not surprising that.

so experienced a field observer as Mr, E. H. Wilson should

consider the plant here figured to be only a strong form of

P. Viali, Delavay. On the other hand, photographs of

P. Littoniana, taken in the field, indicate a degree of

uniformity among the particular plants involved that does

not admit of bemg lightly put aside, so that, in spite of

the fact that the differential characters pointed out by

Mr. Craib are far from convincing, it is convenient, from

the gardening standpoint, to treat P. Littoniana and P. Vialt,

for the moment, as distinct.

The rather striking plant here described is a native of

the mountains of New Caledonia, where it grows on voleanie

rocks at elevations of from 3-5,000 feet above sea-level. It

was originally discovered by Mr. C. Moore, Director of the

Sydney Botanic Garden, and was introduced to European

horticulture by Mr. J. Linden in 1875, The specimen from

which our figure has been prepared was purchased for the

Kew Collection from Messrs. J. Veitch & Sons in 1896,

The distichous compressed leaves, sheathing at the base,

impart to the species a facies recalling that characteristic of

many of the Jridaceae; the flowers, however, are of a

distinctly liliaceous type,and the genus Xeronema, to which

our plant belongs, together with the Australasian genus

Herpolirion, Hook. f., which has a quite different habit,

constitutes the sub-tribe Xeroneminae of the Asphodeleae in

the Natiirlichen Pflanzenfamilien of Engler & Prantl.

In cultivation it calls for the treatment most suitable for

Novemser, 1910.

many South African bulbous plants; potted in a peaty soil

and kept moderately moist all the year round. It enjoys

bright sunshine and flowers annually in June. The perianth

segments and filaments persist and retain their colour for

a month or more. The subhorizontal direction assumed by

the flower-bearing portion of the rachis and the curving of

the pedicels so as to bring all the flowers into an approxi-

mately erect position are constant features which impart

a characteristic aspect to the plant. Xeronema Moorii does

not ripen seeds in this country; it may, however, be

propagated by division.

Description.—/7erh; stem very short, roots fibrous.

Leaves distichous, sheathing at the base, ensiform, laterally

compressed, 14 feet long, 14 in. wide, glabrous, finely dotted.

The genus Pleiocarpa, to which the subject of our plate

belongs, is endemic in Tropical Africa, from which region

twelve species have so far been reported. The one here

figured, P. mutica, is a native of the Cameroons, where it

was first met with by Mr. G. Mann. It has since been

found in Old Calabar, whence it has been introduced to

European horticulture. The material made use of in

preparing our illustration has been derived from a plant

which flowered at Kew in June, 1909; this plant was raised

from a cutting received from the Glasgow Botanic Garden

in 1902. It has thriven well in a stove under the tropical

conditions suitable for species of Jxora, and is striking

from the cultural standpoint owing to the profusion of its

beautiful white flowers. From the morphological point of

view it is interesting on account of the presence in the

flower of five carpels. This peculiarity it shares with

another species, P. rostrata, Benth., while in a third species,

P. salicifolia, Stapf, there are three or four carpels. ‘The

remaining species of Pleiocarpa have only two carpels,

which is the number characteristic of the order Apocynaceae.

The Columnea here described, a native of Costa Rica, like

its congener, C. magnifica, Klotzsch & Hanst., figured at

t. 8225 of this work, does not appear to have been collected

since its first discovery fifty years ago. This suggests that

many of the Central American Gesnerads may have a

limited distribution, and that further exploration of this

region may lead to the introduction of forms that are as

yet unknown. The plant on which our plate is based

flowered in February, 1910, in the collection of Col. R. H.

Beddome, Sispara, West Hill, Putney. This plant was a

young cutting rooted in a propagating frame and grown in

a small pot kept close to the roof-glass of a stove ; another

plant flowered simultaneously in a stove at Kew. Old plants

rarely flower freely, but from the pendent habit assumed by

Novemper, 1910.

their branches, which give off small adventitious roots at

the nodes, they form effective basket-plants, and bear a

considerable resemblance to some of the tropical species of

Aeschynanthus not only in this respect, but in the character

ot the foliage and in the aspect of the flowers. It would

appear, however, from the account given by Oersted, that

under natural conditions this species has a woody stem

which gives off lone straight spreading branches without

adventitious roots.

Descriprion.—Undershrub or herb, epiphytic; stem

woody, somewhat 4-angled, rather tawny, glabrous,

freely branched; branches simple, sparingly adpressed

pubescent upwards, with internodes 5-9 lin. long, in a wild

state, according to Oersted, strict and spreading or upraised,

in cultivated plants flexuous and pendent. Leaves opposite,

shortly petioled, wide ovate or ovate-oblong, acute or sub-

acute, base obtuse or rounded, 5-8 lin. long, 3-5 lin. wide,

fleshy, convex and deep green, shining and glabrous above,

Cotoneaster angustifolia, Franch. Pl. Delay. p. 221.—O. Stapr.

The Chinese Thorn here figured is very closely allied to

the European Everlasting Thorn and to its Himalayan

representative the White Thorn of Nepal. A perplexing

divergence of view has prevailed as to the taxonomic

position and status of these three Thorns. The Everlasting

Thorn or Buisson Ardent which, in 1753, Linnaeus named

Mespilus Pyracantha, was, forty years later, treated by

Medik as a Crataegus and, after a similar lapse of time,

referred by Spach to Cotoneaster. The Nepalese White

Thorn was in the first instance referred, in 1814, to Crataegus,

by Roxburgh, as C. erenulata, but was treated by D. Don in

1825 as a Mespilus, and was only transferred, by Koch, to

Cotoneaster as recently as 1869. The subject of our illus-

tration, which was discovered by Delavay in Yunnan in

1882, was in the first instance referred by Franchet in 1889

to Cotoneaster as C. angustifolia. The agnomen “ Pyra-

November, 1910.

cantha ” definitely associated by Linnaeus with the Buissor

Ardent is believed to have been misapplied ; it is generally

held that the Pyracantha of Greek anthors is our Hawthorn.

Nevertheless the use of the name Pyracantha to connote

the Everlasting Thorn has become popular; that plant is

now, and bids fair to remain, the Pyracantha of gardens,

which fails to appeal to the lay mind either as a Crataegus

or as a Cotoneaster. In this case the popular instinct

appears to be sound, for the suggestions made by

Medik and by Spach, though more satisfactory than that

of Linnaeus, are both more or less open to objection.

Under the circumstances it seems desirable, and it certainly

is more convenient, to adopt yet another suggestion, first

made by Roemer in 1847, and recently endorsed by

Schneider, and to treat the group of species to which our

plant belongs as a genus Pyracantha, closely allied indeed

both to Crataegus and to Cotoneaster, but equally distinct

from either. Pyracantha angustifolia was first introduced

to cultivation by Mr. M. L. de Vilmorin from seeds sent to

Les Barres from Eastern Tibet by Soulié in 1895. A

second set of plants was raised at Kew from seeds sent from

Western China in 1899 by Lieut. Jones. The original

plant at Les Barres bears plentiful crops of berries which in

the late autumn develop a bright orange colour. At Kew,

where P. angustifolia does well on a sunny wall, there is

hardly sufficient sunshine to bring out its best qualities as a

shrub, and in the open, although it survives the winter, it

has not proved perfectly hardy. In the warmer conditions

of South-western England it is more at home, and the

material for an illustration has been obtained from a plant

in fruit in the open in J anuary, 1910, in the garden of Lieut.-

Col. D. Dd. Cunningham at Tormount, Torquay; the

flowering twig which completes our figure was supplied in

July, 1910, from the same bush. The species is best

propagated from cuttings of half ripened wood.

Descriprion.—Shrub; branches spreading; twigs at

first more or less yellow tomentose, in their second season

glabrous, their bark tawny purple, rough with lenticels ;

occasionally some of the twigs modified into stout spines

3-8 lin. long. Leaves clustered on abbreviated twigs or at

the bases of longer ones, persistent, linear-oblong, obtuse

hae

swith a slight mucro, more or less narrowed to the base,

margin recurved, entire or here and there faintly glandular

serrate, 3-21 in. long, 4-5 lin. wide, subcoriaceous, glabrous

above except when young and somewhat polished, beneath

clothed with a grey tomentum which becomes lax and

almost disappears with age; lateral nerves slender, about

8 on each side, impressed above; petioles 2—5 lin. long.

Corymbs rather few-flowered, shorter than the leaves;

peduncles and pedicels grey pubescent. Leceptacle turbinate,

grey pubescent. Sepals wide ovate, persistently pubescent,

8 lin. long. Petals white, suborbicular. Stamens about 20.

Carpels and styles 5. Fruit depressed-globose, orange-

yellow, glabrate, 3-4 lin. long, tipped by the persistent

calyx lobes; pyrenes adnate dorsally in their lower portion

to the receptacle, otherwise free from though surrounded by

the receptacle.

Three members of the South American genus //oulletia

have already been figured in this work : /7. Brocklehurstiana,

Lindl., a native of Brazil, at t. 4072; HH. picta, Linden and

Reichb. f., a native of Colombia, at t. 6305; and H. Lands-

bergi, Linden and Reichb. f., another Brazilian species, at

t. 7362. The interesting species now depicted was imported

from Peru by Messrs. Sander & Sons, St. Albans; there is

an example of the species in the orchid collection at Kew.

H. Sanderi flowered for the first time in Europe in January,

1910, in the nursery of Messrs. Sander & Sons at Bruges;

our plate has been prepared from the specimen then sent to

Kew for determination. It is most nearly allied to 77.

Lowiana, Reichb, f., another Colombian species, but differs

considerably in the details of the lip, more especially in the

very dissimilar side lobes. The Kew plant, which has not

vet flowered, thrives well under the treatment suitable for

Lycaste Skinneri, Lindl, an orchid which is figured at

t. 4445 of this work.

The interesting Pine here figured has much the general

aspect of the Himalayan P. excelsa, Wall., often known as

the Bhutan Pine, or of the Mexican P. Ayacahuite, Ehrenb.,

the Hickory Pine; the cones are, however, very unlike

those of the two species mentioned, The species is most

nearly allied to the Corean Pine, P. koraiensis, Sieb. &

Decemper, 1910.

Zuec., with which it has to some extent been confounded,

The material from which our illustration has mainly been

prepared was derived from one of a group of young trees

raised from seed transmitted to Kew in 1897 by Mr. A.

Henry, who had collected it at Mengtze, in Yunnan.

These trees, which are now from 10-15 feet high, and

are growing very freely, are probably the finest in Europe.

Whilst several of them have borne cones, no male inflores-

cence has yet been produced, and the seeds are consequently

infertile. The figures of the male flowers, male spikelets

and seed here given have been prepared from an authentic

specimen of the plant preserved in the herbarium at Kew.

‘The cones of P. Armandii, which promises to be one of the

most ornamental of the pines of the 5-leaved group, vary

consideraby in size, the largest being 7 in. long and 3-3} in.

Drscriprion.— Tree, reaching 60 ft. in height, bark

hardly resinous, their scales quickly deciduous. Twigs

smooth, glabrous or sparingly beset with small scattered

hairs, at length ash grey. Leaves in tufts of five, slender,

somewhat blunt, very finely serrulate, 4-6 in. long, under

3 lin. wide, triangular in’ section, green above, beneath

with a whitish line along each side of the midrib. Male

catkins clustered, cylindric, yellow, reaching 8 lin. in

The Bromeliad here. figured is a native of the northern

portion of the State of Bahia in Brazil, where it is known

as the Makimbeira; here it grows in association with the

Carod, a very nearly allied plant referred by Baker to the

genus Dyckia as D. Glaziovii, but treated by Mez, perhaps

more satisfactorily, as the type of a distinct genus Neogla-

ziovia. From the Carodé (NV. variegata) the Makimbeira

(N. concolor) differs in its shorter stature and in having its

leaves uniformly white-lepidote, the younger parts are

indeed almost woolly; the leaves of N. variegata are

glabrous or only very minutely lepidote, and when fresh

are conspicuously marked with lighter transverse bars

which in dried specimens become obscure or disappear

entirely. The leaves of both species furnish fibre; that of

the Caroa is well known and comes chiefly from the

Queimadas District; it is made into ropes for binding

Decemser, 1910.

packages of tobacco. These ropes have a breaking strain

of 3 tons to the square inch; they are, however, very

sensitive to attack by alkalis. The fibre of the Makim-

beira is less well known and is of a softer and poorer

quality ; attention to this fibre and to the plant itself was

first called in 1902 by His Majesty’s Consul at Bahia in a

letter to the Imperial Institute. In 1903 living plants of

the Carod and the Makimbeira were received at Kew from

the Imperial Institute; the latter, which flowered for the

first time in a tropical greenhouse in September, 1909,

provided the material for the figure now given. NV. concolor

has proved, as compared with Bromeliads generally, to be

of very slow growth under the artificial conditions of a

tropical collection; possibly under natural conditions it

may thrive more luxuriantly. At Kew it is planted ina

pot in peaty soil and kept in a warm moist house where it

receives shade from bright sunshine.

The Hamamelidaceous genus Curylcpsis is rather widely

distributed throughout Eastern Asia from the Eastern

Himalaya to Japan. So far thirteen species have been

reported; of these four seem confined to Southern Japan

and six occur in Eastern and Central China, only one of

these, C. sinensis, Hemsl., extending from Kiang-si, through

Hupeh, as far as Szechuan in Western China. In the

western portion of the region occupied by the genus the

species seem less numerous, one only having been collected

-in Bhutan, another in the Khasia Hills and a third in

Manipur. The species here figured was collected at

December, 1910.

Chang-yang in Western Hupeh by Mr. E. H. Wilson in

May, 1900, when seeds were sent to Messrs. J. Veitch &

Sons, growing in the same general region as C. sinensis, to

which and to C. Henryi, Hemsl., another species from

Hupeh, it is most nearly allied. From C. sinensis our

plant is, however, readily distinguished by its leaves which’

when mature are quite glabrous, by its distinctly exserted

stamens and by its red-brown not yellow anthers; from

C. Henryi it differs by having more rounded petals and

very much shorter calyx-lobes. The flowering spike of

Corylopsis is the termination of a young ultimately leafy

branch. The empty basal protective scales do not, as is

the rule, fall away when the buds open; above these

scales are a few bracts of stipular nature in association

with one or more of which leaves are produced; above

these again come the true floral bracts, each with a sessile

axillary flower and lateral bracteoles. The true character

of the inflorescence is evident by the time the seeds are

ripe, for the leaf-bearing base of the axis has by then

become woody. The plant from which our figure has been —

prepared was raised by Messrs. Veitch in their nursery at

Coombe Wood, where it has flowered regularly in April

for some years past, and is then decidedly attractive owing

to the soft primrose-yellow colour and the pleasing fragrance

of its blossoms. It appears to be quite hardy ; it grows well

in an open sandy loam and can be propagated by cuttings.

Descriprion.—Srub ; 5-6 ft. high, of bushy rounded

habit; branches reddish when young, glabrous. Leaves

shortly petioled, elliptic, suddenly shortly acuminate or

acute and mucronulate, somewhat cordate at the base,

38-4 in. long, 13-2 in. wide, reddish-purple and sparingly

silky hairy on the nerves beneath when young, becoming — a

dark green above, more or less glaucous and_ perfectly

glabrous beneath when full grown, coriaceous; main veins

6-7 on each side, straight and parallel, the lowest pair

giving off 4-5 strong nerves outwards; veins all prominent

beneath and extending beyond the margin in setaceous

teeth; petiole glabrous, about 1 in. long. lowering —

branches spicate, nodding, bracteate, 1-2 in. long, } in-

wide, lateral on the naked wood of the previous year,

10-15-flowered; main-axis pilose and beset at the base

with a few empty membranous scales; stipular bracts 2-4,

concave, semi-translucent, pale yellowish-green, orbicular,

2 in. in diameter, glabrous outside, ciliate, silky within ;

floral bracts similar in colour and shape but smaller and

hairy on both sides. Calyx greenish-yellow, hairy, with

5 ciliate rounded lobes about one-third the depth of the

tube. Petals 5, primrose-yellow, spathulate orbicular, } in.

wide, narrowed to a claw about 34 in. long. Stamens 5,

the red-brown anthers distinctly exserted. Nectaries 5,

sharply 2-dentate, somewhat longer than the calyx-lobes.

The attractive Jucobinia here figured is a native of

Uruguay, whence it was introduced into cultivation in

1899 by Mr. J. Sallier of Neuilly-sur-Seine. The habit of

: the plant is unusual in the genus, for most of the species

4 of Jacobinia have erect stems; in ./. suberecta, however, the

stems are prostrate and form a compact mass which gives

off a number of erect flowering branches. This character-

istic renders it a very suitable plant for culture in a hang-

ing basket. A pleasing grey-green effect is produced by

the velvety pubescence which clothes the leaves and stems,

to which the bright scarlet flowers afford a striking contrast.

‘The material from which our figure has been prepared was

presented by Col. R. H. Beddome, who successfully flowered

December, 1910.

it in his stove collection at West Hill, Putney, in July, 1909.

Col. Beddome informs us that this /acobinia does not flower

with him when grown as a large plant under ordinary

stove conditions. But young succulent cuttings, rooted in:

the spring in the propagating frame, planted in small pots

in a mixture of leaf-mould, loam, sand and_pea-shaped

crocks, and slightly fed with fertilizer, have flowered freely

in his collection when kept on shelves quite close to the

glass.

The figure of the striking Dendrobium here given has

been made from a plant presented to the Kew collection of

orchids by Messrs. Sander & Sons, St. Albans. It is most

nearly allied to the Philippine D. Dearei, Reichb. f., but

differs from that species in having larger flowers which, in

addition to some minor structural points, are marked by the

presence of purple stripes on the side lobes and base of the

lip. Introduced to cultivation only in 1909, sufficient time

has hardly yet elapsed to admit of a definite judgment as to

its cultural requirements. So far it has thriven well at Kew

under the treatment that answers for D. Dearei ; tropical

conditions with plenty of water both at the root and over-

head while new growths are being formed, and rest in a

dry atmosphere afterwards. The imported plants have

flowered in October, but it is possible that when the species

has become established in this country they may flower in

spring.
