This ornamental stove Aroid is a hybrid raised by the
firm of Messrs. Makoy of Liege, for which they were awarded
a Certificate of Merit by the Royal Agricultural and Botanical
Society of Ghent in 1887. Its parentage is not mentioned,
but judging from the purple tint on the under surface of its
leaves, a coloration which is unusual in the genus, it is
possible that P. verrucosum, Mathieu, may have been one of
its parents. When young the leaves are deeply tinged with
coppery brown, but as they become older this colour almost
disappears, as in the leaf figured. For a climbing species it
appears to be of comparatively slow growth, since the plant
at Kew, from which our figure was made in May last, was
acquired in 1898, and is now only about 8 feet high, with a
spread of about 6 feet.

Description.—Stem climbing, rooting, 1-2 in. thick,
clothed with brown fibrous scale-leaves on the upper part.
Leaves spreading, 1-3 in. apart ; petiole 11-2} feet long, in
the larger leaves about } in. thick at the middle, terete,
with a slightly rough surface, green ; blade 14-2} feet long,

January, 1908.

11-18 in. broad, deeply cordate-ovate, acute, shortly
pinnatifidly lobed, with the roundish basal lobes separated
by a narrow acute sinus 43-7 cm. deep, bright deep green
above, dull purple between the green veins beneath,
changing to green with age; midrib flat above, very
prominent beneath ; primary veins about 7 on each side of
the midrib, with the 2 basal ones close together, the others
distant ; impressed above, prominent beneath ; basal lobes
with 5-6 primary veins, all united into one at the base,
where it is shortly denuded at the sinus. Inflorescence
solitary in each axil. Pedunele short, green, with whitish
lines. Spathe with an ellipsoid tube 3 in. long, of a rich
purple-crimson, with scattered spots of crimson-brown and
numerous rows of minute white dots outside, and bright
deep carmine inside; limb 4-44 in. long, 21-22 in. broad,
boat-shaped, with a short convolute point, hght green,
spotted with red outside and carmine, with darker spots
inside, shading into white at the margins. Spadia 6-65 in.
long, 4-2 in. thick, terete, acute, slightly curved forwards,
creamy-white.—N. E. Brown.

Curtivation.— While in the genus Anthurium hybrids of
garden origin are numerous and in the genus Richardia there
are several, the plant now figured is the only hybrid Philo-
dendron that has been raised artificially. This plant, which
was purchased for Kew as an ornamental foliage plant, has
been grown under moist tropical conditions in the Aroid
(No. I.) House, where it has climbed up the stem of a tree-
fern to the height of about 8 feet, and it was not until it
developed flowers at Kew that the decided attractiveness of
its inflorescence, both as regards size and colour, were
revealed, Most of the Philodendrons have large, handsome
and fragrant flowers, and are excellent plants for clothing
pillars, palm-stems and back-walls in tropical houses,
purposes for which they are largely employed at Kew both
in the Palm House and in the Aroid House, near the
main entrance.—W,. Warson.

carpellis albo-tomentosis distincta.

Herba perennis, caule glabro. Folia biternata; foliola late oblonga vel
subelliptica, lateralia obliqua, apice brevissime acutata vel acuminata, basi
obtusa, 8-10 cm. longa, 4-6 cm. lata, supra glaberrima glaucescentia, subtus

This is one of a group of yellow-flowered Paeonies from
the Caucasus, the others being P. Wittmanniana, Stev.,
which was figured on Tab. 6645, and P. macrophylla,
Lomakin. All three are very closely allied, and their
discrimination in the dry state is difficult, if not, indeed,
sometimes impossible. Alboff in his Prodromus Florae
Colchicae (in Act. Hort. Bot. Tifl. vol. i. p. 14) went even
so far as to treat P. Wittmanniana and P. macrophylla as
forms of P. corallina, Retz., and he would no doubt have
dealt with P. Mlokosewitschii in the same way. As, how-
ever, no experiments have been made to test the constancy
‘of the characters which have been relied upon in dis-
criminating between those forms, and as they appear readily
distinguishable when seen in the living state it is certainly
more expedient to treat them at present as distinct species.
P. Mlokosewitschii was discovered by Mlokosewitsch near
Lagodekhi in the eastern part of the Central Caucasus,
whilst typical P. Wittmanniana is a native of Adsharia in
the basin of the Tshorok River, south of Batum. Lomakin
(in Act. Hort. Bot, Tifl. vol. ii. p, 283) described, however,

January, 1928,

a variety of P. Wittmanniana from the Talysh with carpels
tomentose as in P. Mlokosewitschii. The distinctive charac-
ters of P. Wittmanniana and P. Wlokosewitschii are thus
reduced to differences in the colour and pubescence of
the leaves and possibly in the extent to which the petals’
open out; at the same time the area of the former is
extended right across the Caucasian region from the Black
Sea to the Caspian. The specimen figured was communi-
cated by Mr. Gumbleton of Belgrove, Queenstown, Ireland,
where it flowered in May. Mr. Gumbleton obtained the
plant from Mr. Max Leichtlin of Baden-Baden. Since then
young plants have been raised at Kew from seeds received
from the Tiflis Botanic Garden.

Description.— Herbaceous, perennial ; with stout glabrous
stems. Leaves biternate; leaflets broad-oblong or subelliptic,
the lateral oblique, tips very shortly pointed or acuminate,
base obtuse, 3-4 inches long, 1$-24 inches broad, glabrous
and dark blueish-green above, shortly pubescent and pale —
glaucous below, margins and nerves red; petioles and
petiololules glabrous. Flowers open, about 4-5 inches in
diameter ; pedicels glabrous, reddish, 4 inches long. Sepals
unequal, one oblong-lanceolate, constricted above the base,
the other suborbicular, very obtuse, both glabrous. Petals
about 8, roundish, concave, yellow. Stamens very numerous ;_
filaments twice as long as the anthers. Carpels 3, oblong, —
whitish-tomentose ; stigmas subsessile, purple.—O. Srapr.

Cuurivation.—This, the most handsome of the yellow-
flowered Paeonies, thrives under the treatment suitable for .
the other forms belonging to the herbaceous section of the
genus, and appears as hardy and as satisfactory under culti-
vation as they have proved. The glaucous leaves with their red
veins and margins contrast sufficiently with the more purely _
green leaves of P. Wittmanniana (B. M. t. 6645) to attract
attention, and it is certain to become a favourite with
gardeners. The fine sulphur-yellow flowers are more striking |
than the whitish-yellow blooms of P. Wittmanniana, though
the latter areas a rule larger and more decidedly yellow than
was the case in the plant figured at t. 6645.—W. Warson. au

Viburnum (§Tinus) utile, Hemsl. in Journ. Linn. Soc. vol. xxiii. p. 856;
species inter affines foliis crassis supra glabris subtus dense tomentosis
facile distinguitur.

Frutec 1-1°5 m. altus, ramulis floriferis elongatis rectis primum stellato-
pubescentibus cito glabrescentibus. Folia persistentia, breviter petiolata,
crassa, coriacea, lanceolato-oblonga vel interdum ovato-oblonga, saepius
2-5-8 em. longa, rarius nsque ad 15 cm, longa, obtusa, integerrima, supra
glabra, nitida, subtus pilis stellatis multiradiatis incano-tomentosa, venis
primariis paucis supra eens subtus elevatis. ores omnes conformes,
circiter 1 cm, diametro, dense cymosi; cymae compositae, umbellatae,
terminales, densae, hemisphaericae, 5-8 cm. diametro, breviter pedunculatae -
pedicelli ovario breviores, pubescentes. Calyx glaber, nitens, dentibus
ovatis obtusis circiter 1 mm. longis. Corolla rotato-campanulata, vix
1 cm. diametro, lobis rotundatis. Stamina breviter exserta. Ovarium
l-loculare, 1-ovulatum, ovulo ab loculi apice pendulo; stylus brevis,
crassus, carnosus, pilis stellatis paucis ornatus, stigmate capitato. Fructus
fere siccus, oblongus, compressus, circiter 8 mm. longus, laevis, glaber.

Specimens of this species were first recorded by Hance
(Journ. Bot. 1882, p. 6) as V. cotinifolium, Don, var. y,
Hook. f. & Thoms. ; but Hooker and Thomson, so far as our
investigations go, never published such a combination ; nor
do we find herbarium specimens thus designated. V. cotini-
folium, Don, is indeed a very different species, closely
resembling the native V. Lantana, Linn. It is figured in
_ the Botanical Register, 1834, t. 1650.

The present drawing of V. utile was made from materials
supplied by Messrs. James Veitch & Sons, who raised it
from seed sent home by their collector, Mr. E. H. Wilson ;
but it was first discovered near Ichang by Mr. T. Watters,
of the British Consular Service, in 1880. Kew now
possesses dried specimens from numerous localities in Hupeh
and Szechuen. V. utile var. suaveolens, Franch. mss., from
Yunnan, collected by Delavay and Henry, is regarded by
Mr. A. Rehder as a distinct species; but the differences are
not evident, and he has not yet published a description.

January, 1908,

Upwards of fifty species of Viburnum have now been
recorded from China and the area of the genus encircles the
northern hemisphere in temperate regions, and extends into
the southern hemisphere in Madagascar as well as the Andes,
where there are species so like some of the Chinese ones as
to be easily mistaken for these in a dried state.

Descriprion.— Shrubby, 4-5 ft. high, with long, straight
flowering-branches, at first clothed with a stellate pubescence,
later glabrescent. Leaves persistent, shortly stalked, thick,
leathery, lanceolate-oblong or ovate-oblong, usually 1-3 in.
long, sometimes 6 in. long, obtuse, quite entire, smooth and
shining on the upper surface, lower surface densely clothed
with a white indumentum composed of multiradiate, stellate
hairs; primary veins few, impressed above, elevated below.
Flowers all similar, 1~} in. across, densely cymose; cymes
compound, umbellate, terminal, 2-3 in. across, shortly
stalked; pedicels shorter than the ovaries, pubescent.
Calyx smooth; teeth small, obtuse, about ,; in. long.
Corolla rotate-campanulate ; lobes broad, rounded. Stamens
a little longer than the corolla. Ovary 1-celled, l-ovuled.
Fruit dry, oblong, flattened, smooth, black, about 4 in. long.
—W. B. Hemstey. :

CuLtivation.—As seen growing in the Coombe Wood
Nursery last spring, this shrub gave the impression that it
would eventually prove one of the most desirable of recent
introductions from China. The habit was neat and bushy,
and the flowers very freely borne. Like the other species of
the genus, it can, no doubt, be increased easily by cuttings,
and like them, too, it will thrive in ordinary well-cultivated
ground, especially where the soil can be kept from getting
excessively dry during the summer months. Mr. Wilson
records the species as growing on limestone.—W. J. Bran.

The genus Herbertia is confined to Southern and Central
America, and includes, so far as is known, some fourteen
species whereof, in addition to that now figured, the only
ones hitherto met with in cultivation appear to be H.
coerulea, H. Drummondiana and H. pulchella (B.M. t. 3862).
Some authors have preferred to employ for this genus the
name Alophia, given by Herbert in this work at t. 3779,
regarding Herbertia as a synonym. According to Dalla-
Torre and Harms the date of publication of Alophia was
1838 ; as a matter of fact this name was not published till
Feb. 1840, whereas in the reissue of Sweet’s British Flower
Garden, which is dated 1838, there is a figure of H. pulchella,
while the plate itself bears the signature:—Pub. by R.
Sweet, Oct. 1827.

For seeds of the species now figured Kew is indebted to
Dr. C. B. Cantera, of the Natural History Museum, Monte-
video, who collected and forwarded them in 1903. Corms
raised from these seeds flowered here for the first time in a
greenhouse in May, 1907.

Cuttivation.—erbertia amatorum is the most handsome —
species of this genus so far brought into cultivation. The
beautiful dark porcelain-blue flowers are very fugitive, but
the plants bloom continuously for several months. The
Herbertias call for the same treatment as Figidella and
Ferraria, to which they are nearly allied; they require
protection from frost, a light sandy soil, and a sunny
position in a frame or greenhouse. It is possible that in |
the warmer parts of the United Kingdom this and some |
of the other species could be grown in a sheltered sunny
border in the open air—W. Watson.

JANUARY, 198,

More than forty years ago Andrew Murray pointed out
that this Chinese tree, introduced by Fortune, was not, as
at first supposed, the Japanese “ Larix conifera, nucleis
pyramidatis, foliis deciduis” of Kaempfer (Amoen. Exot.
p. 833); therefore Pinus Kaempferi, Lamb. (Genus Pinus,
ed. 3, 1832, p. 7) and the original Abies Kaempferi, Lindl.
(Penny Cyclop. 1833, vol. i. p. 34) are not synonyms of
Pseudolarix Fortunet. Moreover, these names were applied
to the Japanese tree twenty years before the Pseudolariz
was discovered. Lindley’s identification has caused much
confusion in the synonymy of this species, but although
Murray cleared it up, he did not introduce a new name,
Kaempfer’s tree is Larix leptolepis, Gord., yet Franchet &
Savatier, following others, cite it under Larix Kaempferi,
Carr. (Pseudolari« Fortunei, Mayr), which is not a native
of Japan, and was not, up toa few years ago, even cultivated
in that country. It is true that Franchet & Savatier record
it, on the authority of Miquel, as being in cultivation in
Japan, adding that it was also very probably wild; but
Mayr states positively that it was not in cultivation there
up to 1890. Mayr has taken the step rendered necessary
by Murray’s elucidation of the facts, and the late Dr. M. T.
Masters has accepted Mayr’s name in the most recent
revision of the Chinese Coniferae (Journ. Linn. Soc. Nov. 1,
1906, vol. xxxvii. p. 424), as he had previously done in the
place cited above. But as long ago as 1847 Endlicher
(Synopsis Coniferae, p. 130) cited Kaempfer’s Larix conifera
under his Pinus leptolepis, syn. Abies leptolepis, Sieb. &
Zuce., having apparently overlooked the publication of
Pinus Kaempferi, Lamb.

Fortune discovered this tree in the mountains of Chekiang, :
and sent seeds to England in the winter of 1853. He had
formed a high opinion of its value as an ornamental tree,
_ and took infinite trouble to ensure its introduction. Writing
in 1860 he says: “I used every means in my power to
introduce its seeds in large quantities and in good condition.
They were sent by the overland mail, some in letters and
some in small packages, for several years in succession,
and were often sown in England in less than two months
from the time they were gathered from the tree in China.
Out of all sent home only one despatch vegetated freely ;
all the others were complete failures, All the plants of

any size now in England were dug up in the woods of
China and sent home in Wardian cases. In cultivation
this species, like many of its race, prefers a loamy soil and
a hilly or undulating situation. I would advise the
possessors of very small plants to keep them in shady
places during the hot summer months. In nature the
young plants are all reared under the shade of trees.”

Pseudolariz Fourtunei is apparently a rare tree in its
native country. Fortune found it only in the Province of
Chekiang ; Franchet records it, with doubt, from Kiangsi,
and Wilson states that it occurs wild on the Lushan,
Kiangsi, where, however, he found only a few small trees.
In this country it is still uncommon ; the finest specimen
we have seen is in the gardens at Penjerrick, near Falmouth.
Although perfectly hardy, it cannot be said to flourish at
Kew, where there are several trees. One of these, near the
clump of Celtis australis and Quercus Ilex, to the left on
entering the gardens from Kew Green, flowered profusely
in June, 1907, when the drawing was made. Fully
developed cones followed in abundance on the uppermost
branches, containing apparently fully developed seeds,
even to the albumen, but no embryo was formed. The
only perfect seeds we have seen are some of Fortune's
collecting, preserved in spirit at Kew, from one of which
was obtained the previously undescribed embryo.

Descriprion.— A tree with the habit and appearance of a
larch, sometimes as much as 120-130 ft. high ; branches some-
what stratified, as in the Cedar of Lebanon. Leaves deciduous,
needle-shaped, usually 1-14 in. long, sometimes as much as
3 in. long on vigorous shoots, thin, flexible, not prickle-
pointed, whorled and stellately spreading in the lateral
spurs, spirally arranged in the primary branches. Male
catkins clustered at the tips of lateral spurs without any
leaves below, recurved, including the slender stalk about
in. long. Anthers about 20 in each catkin. Female
catkins globose, about 2 in. in diameter, borne at the tips of
lateral spurs, with a few spirally arranged leaves below.
Cone ovoid-oblong, 13-2 in. long. Scales 2-seeded, ovate,
$—14 in. long, obtuse or notched at the tip, leathery, woody
at the base, shortly stalked, loose, spreading, falling with
the seeds, Seeds winged, equalling the scales, and, as the

scales open, the wings project beyond them, giving them
the appearance of having a white margin. Embryo straight,
club-shaped, about } in. long ; cotyledons 4, about one-third
as long as the radicle.—W. B. Humstey.

Cuitivation.—As a garden tree the Golden Larch is
perhaps the most beautiful of the Larix group. It is easily
distinguished from the true Larches, even in the absence of
cones, by the larger size and greater substance of the leaves.
At all times attractive, it. is especially so in spring, when
the young foliage is a beautiful shade of tender, yellowish
green, and again in autumn, when the leaves turn a rich
golden colour before falling. It thrives best in a good
well-drained loamy soil. At Kew the natural soil of the
gardens is too poor for this tree to succeed well. It is only
by mixing with it a large proportion of stiff loam that
Pseudolari« Kaempferi can be made to develop its char-
acteristic beauty.—W. J. Bran.

This is another of the numerous ornamental Chinese
plants introduced by Messrs. James Veitch & Sons, through
Mr. EK. H. Wilson. It is an exceedingly free-growing
subject, and seedlings exhibit a considerable amount of
variation in colour, Dried specimens of it were at first
associated, as a variety, with the original F. chinensis,
Fisch. & Mey. (B. M. 1838, t. 3653), which is the same as
R. glutinosa, Libosch ; but fully developed cultivated plants
present a very different appearance. Unfortunately it is
not so hardy as the older one, which inhabits the northern
province of Chihli in the neighbourhood of Peking, whereas
fi, angulata is a native of the central provinces of Hupeh
and Kweichau. There are several other species of this
genus, which is confined to the Chinese region. 2. rupes-
tris, Hemsl. (B. M. 1891, t. 7191) is very different, and
should perhaps be separated generically,

Freervuary, 1908,

Descriprion.— Biennial or perennial, clothed with glandu-
lar hairs. Stems in cultivation 4-6 ft. long. Leaves
alternate, stalked, ovate-oblong, lower 6 in. long, gradually
smaller upwards, uppermost bract-like and sessile, irregu-
larly lobed and toothed or only toothed ; teeth very acute.
Flowers pink, tinged with yellow and beset with darker
spots in the throat, axillary, solitary, distinctly stalked,
nodding ; stalks shorter than the flowers. Calya campanu-
late, about 1 in. long, deeply 5-lobed ; lobes narrow, pointed,
uppermost longer than the others. Corolla 3-4 in. long ;
tube broad, ventricose, curved; limb .2-lipped, 24-23 in.
across, lobes rounded, spreading. Stamens 4, didynamous,
much shorter than the corolla; filaments slender; anthers
connivent in pairs with divergent cells. Ovary glabrous ;
style included. Capsule not seen.— W. Borrine Hemsury.

Cuirivation.—This handsome herbaceous plant is pro-
bably a perennial, but under cultivation it is most satisfactory
when treated as a biennial. The seeds are sown in a little
warmth in May, and the young plants are grown in a frame
till the followmg May, when they are planted in an open
border, where by July they are from 4 feet to 6 feet high
and in full flower. Or they may be grown in pots and
treated as greenhouse plants. In the warmer parts of the
country this plant has proved hardy. It ripens seeds freely
at Kew.—W. Warson.

The species of Codonopsis, of which twenty-two are now
known, have been critically examined by Mr. T. F. Chipp, who
considers that they admit of arrangement in four sections dis-
tinguished by the relative position of the floral whorls. In
one section, limited to the single species C. Tangshen, figured
at t. 8090 of this work, the calyx is inferior. In another,
represented by C. rotundifolia, figured in two varieties at
t. 4942 and t. 5018, but including ten other species, the
calyx is half-superior while the corolla is superior. In a
third section, including seven species, none of which have
yet been figured in this work, the calyx and corolla are both
half-superior. In the last section, which includes only three
species, the calyx is superior. It is to this section that C.
convolvulacea, the plant now figured, belongs; within the
section our plant stands alone in having the corolla-lobes
free to the base. SO

Frsrvuary, 1908.

Like the other species, C. convolvulacea is confined to
Kastern Asia, but its area of distribution within the region
is somewhat wide, for it extends from the Shan Plateau in
Central Indo-China northwards into Yunnan and Szechuan
and thence westward into Central Tibet; the flowers in
Tibetan examples are smaller than in the Chinese and Shan
specimens, but do not materially differ in other respects.

Extensive as the area from which specimens have been
reported actually is, it seems possible that it may prove to
be wider than these indicate. The plant from which our
figure was prepared was presented to Kew by Mr. M.
Leichtlin of Baden-Baden in 1906 and flowered here in
August, 1907. Its flowers were larger than those of
Burmese specimens and than those of all the Chinese speci-
mens except in a single gathering communicated by Mr. A.
Hosie from between Batang and Tachienlu, and thus
differed as much from these, in a converse direction, as the
flowers of Tibetan specimens do. But, like the Tibetan
ones, they agree with the Chinese and Burmese flowers in
every character save that of size.

When Mr. Leichtlin sent this plant to Kew he suggested
that it might be a Campanulaceous species new to cultivation,
but added no note as to its origin. With a plant sent by
him at the same time to Mr. H. J. Elwes, in whose collection
at Colesborne it flowered contemporaneously with the plant
at Kew, Mr. Leichtlin gave a locality in the North-West
Himalaya. In response to a request for more definite
information, Mr. Leichtlin has most obligingly stated that
these plants were derived from seeds communicated to him
by the late Mr. W. Gollan, Superintendent of the Botanic
Garden at Saharanpur in Northern India ; these seeds were
obtained in the North-West Himalaya by one of Mr.
Gollan’s native collectors. Hitherto no Indian botanist has
communicated herbarium specimens of C. convolvulacea
from any portion of the Himalaya, but, when regard is had
to the care which characterises the work of Mr, Leichtlin
and characterised that of Mr. Gollan, the possibility that
C. convolvulacea may occur in the North-West Himalaya
should not be overlooked by botanical travellers,

Descriprion.—A perennial herb. Stems slender, smooth,
twining, sparingly branched. Leaves membranous, usually

quite glabrous, mostly alternate, ovate-lanceolate or ovate,
2—2 in. long, 1-1} in. wide, subacute or acute or acuminate,
with cuneate or truncate. or sometimes cordate base, the
margin subentire or faintly toothed ; petioles slender, }—3 in.
long. Peduncles smooth, long, twining. Calyx superior,
the tube obconic, smooth, {-} in. long, the limb 5-lobed,
lobes triangular or lanceolate, usually acute, 1-3? in. long,
4-} In. wide, usually glabrous, sometimes sparingly ciliate.
Corolla campanulate, blue, 5-partite to the base; lobes
3-13 in. long, triangular or oblanceolate, acute and often
finely mucronulate ; limb 14-2 in. across. Filaments
glabrous, spreading, each with an ovate ciliate appendage
at the base on the outer side; anthers oblong, glabrous,
their dehiscence introrse. Stigma 3-lobed. Capsule trun-
cate or subconic, 3-valved, 4—} in. long.

Currivation.—Though the individual flowers are striking,
C. convolvulacea cannot be reckoned a showy plant; the
Kew plant had indeed only one flower open at one time.
It does not, however, compare unfavourably with the other
species that have been in cultivation, most of which,
as stated by Dr. Lindley, are plants with dull-coloured
flowers recalling those of an A/ropa, with the habit of a
miniature Canarina. From its behaviour Mr. Leichtlin is
inclined to think that the present species may be a biennial.

It has been grown at Kew as a pot-plant, in a cold frame.—
D. PRaIn.

Rehder in Sargent, Trees and Shrubs, vol. i. p. 73, t. 37.

This is apparently a rare tree in Japan, so far only found
in woods in Central Hondo. It was named after T'schonoski,
one of Maximowicz’s collectors, who discovered it at Siba-
sirl at the foot of Fujiyama; subsequently in 1892 it
was collected near Nikko and at the foot of Asamayamo
north of Tokio by Professor Sargent, who introduced the
tree into the Arnold Arboretum and, in 1897, presented
plants to Kew. It belongs to the section Hriolobus which
was originally proposed as a genus by Roemer and recon-
stituted as such by Rehder, l.c., who includes in it four
species, all Asiatic.

Descriprion.—A tree, 30-40 ft. high, trunk 1 ft. in

Fesruaky, 1908.

feceptacle + in. long, whitish-villous. Calyx-teceth ovate,
acute, spreading in flower, erect and persistent in fruit.
Fruit more or less globose, about 1 in, in diameter, greenish-
yellow and more or less red on one side with small lenticels ;
flesh austere, gritty—Ovrro Srapr.

CutrivaTion.—The most striking character of this rare
and interesting tree is its erect, open, and rather formal
habit. It has been grown at Kew quite unprotected for
ten years, and may therefore be considered hardy.’ Like
the other members of the same genus it enjoys generous
treatment. It has grown well at Kew in a border of rich
loam. It flowered in the spring of 1907 better than it had
done previously, this being partly due to increasing age
and partly, no doubt, to the splendid ripening weather of
the previous autumn.—W. J. Bran.

The handsome Potentilla here figured is a native of the
province of Yunnan, in south-western China, where it was
discovered by the Abbé Delavay about twenty years ago,
growing in caleareous soil on Mt. Yen-tze-hay, at about
10,500 ft. elevation. It was described as a variety of the
Himalayan Potentilla Griffithii, Hook. f., by Franchet, who,
however, pointed out that it has much larger concolorous
leaflets, not white-tomentose beneath as in the typical form ;
also larger foliaczous stipules and much larger golden
yellow flowers. It has now appeared in cultivation, having
been submitted for determination in May last by Messrs.
Bees, Ness, Neston, Cheshire, with the information that it
had been received from Yunnan. Now that living speci-
mens are available it is evident that the plant referred to
cannot be P. Griffithit, Hook. f.; though a member of the
same group, it 1s quite unlike the Himalayan plant in
general aspect, and is clearly a distinct species, for which
the varietal name, concolor, may be retained as the specific
appellation. P. Grifithii has leaflets of about half the
size of the present species, and these are invariably densely
white-tomentose beneath, and the tomentose character also

Fresrvary, 1928,

extends to the sepals and bracteoles, while the flowers
generally are not half as large. P. concolor is probably the
finest yellow-flowered species known, and promises to be a
very showy garden plant. It will probably prove as hardy
as its Himalayan congeners.

Descriprion.—A_ perennial herb over a_ foot high.
Branches suberect, stoutish, pubescent. Radical leaves not
seen; cauline leaves petiolate or the upper subsessile,
pinnate or the upper trifoliolate; rachis pubescent ; leaflets
obovate-elliptical, deeply toothed, attenuate at the base,
1-2 in. long, concolorous, pubescent ; stipules ovate-oblong,
obtuse or subacute, entire, slightly pubescent, $-1 in. long.
Cymes lax, few-flowered. lowers very large, over 1} in.
across. Ca/yx spreading, | in. broad, with five bracteoles
alternating with the sepals and similar to them in shape;
lobes ovate-oblong, acute, slightly pubescent. Petals
broadly obcordate, bilobed at the apex, }—} in. broad, deep
yellow, with an orange-coloured blotch at the base. Anthers
elliptic-oblong, margined with purple. Achenes and style
glabrous.—R. A. Ronre.

CuLtivation.—Only a few of the numerous species of
Potentilla have won recognition as garden plants, and the
best of these is P. Russelliana (B. M. t. 3470) which is a
hybrid, said to have been raised at least 75 years ago by
a Mr. Russell of Battersea, from P. atrosanguinea and
P. nepalensis. The plant here figured is, in habit and
general characters, very similar to P. Russelliana; but
whilst the latter has rich blood-red flowers, those of the
present plant are bright yellow. These are produced in
May, and the plant is evidently quite hardy, thriving under
the treatment that answers for the garden representatives
of Geum and Geranium.—W. Warson.

This Larch was discovered in 1838 by Griffith in Bhutan
on the mountain slopes above Woollakoo, a village some-
what sonth-west of Punakha, between 6000 and 9600 fect.
In 1848 it was found by Sir Joseph Hooker on the slopes
of Nango Mountain in Eastern Nepal, and in the follow-
ing year in the Lachen Valley in Sikkim. More recently
it has also been recorded from the Chumbi ‘Valley at
10,000 feet. Its western limit lies, according to Nepalese
sources, near the headwaters of the Kosi River. In Sikkim
it appears, according to Mr. Gammie, at 8000 feet, becomes

plentiful at 9500 feet and ascends to 12,000 feet. Griffith
describes it as a small tree, and so Sir Joseph saw it in
Nepal; but in Sikkim it is as much as 65 ft. high. In
its natural habitat it prefers dry, rocky soil and grassy
slopes, and is, like our larch, a light-loving tree. It is
known in Sikkim as ‘Sah’ or ‘Saar,’ and is cut up in
planks which Sir Joseph describes as soft and small but
very durable. The drawing was made from specimens in
cultivation at Kew, with the exception of the male catkins
which were figured from a specimen supplied by Sir
Edmund Loder of Leonardslee, Horsham, Sussex.

Descriprion.— Tree 20-65 ft. high, with slender trunk,
long branches and very long, cordlike, pendulous branchlets,
pilose when quite young, pale at first, then dark, rough
from the small persistent leaf-cushions. Winter buds
globose-ovoid, inner scales hyaline, very broad, clawed,
floccose-villous. Leaves needle-shaped, those on the cylindric
short-shoots fascicled, 30-50, and spreading, subacute, about
1 in. long, 3; in. wide, flat, bisulcate on both sides,
bright green, with glaucous lines above. Male flowers
ovoid, yellowish, tinged with red, about 4 in. long, shortly
pedicelled ; appendage of connective small, ovate. Female
flowers cylindric, dark-purple, over 1 in. long. Carpels
(bracts of the older authors) lanceolate, subulate-caudate,
reflexed from the middle; ovuliferous scales very broad,
rotundate, half as long as the carpels. Cone cylindric, up to
almost 3 in. long, over | in. in diameter, purplish-brown ;
scales broad, truncate or subemarginate-obovate, up to 3 in.
long and broad. Seed obovoid, scarcely 4 in. long; wing
broad, obliquely elliptic, } in. long-—Orro Srapr.

Cutrivarion.—None of the other Larches and very few
Conifers have proved so difficult to cultivate in Great
Britain as this Himalayan species. Seeds have been
imported to Kew on several occasions, and asa rule they
have germinated freely. But the young plants rarely live
more than a few years. The average climate of Great
Britain is doubtless unsuited for it, and the resulting ill-
health renders it peculiarly subject to the attacks of the
Lareh-blight (Chermes ahietis). During the last twenty
years it has not lived to attain a greater height at Kew

in the open than 3 ft. Apart from its susceptibility to
insect attack it ought to thrive in the gardens of the milder
parts of England and in many parts of Ireland. The tree
at Leonardslee is, indeed, apparently quite healthy. Yet
it still remains the fact that this Larch is one of the rarest
of cultivated Conifers, although numerous young plants
have been distributed from Kew.—W. J. Bran.

MONOGRAPHS

FROM THE

THIRD SERIES

OF THE

BOTANICAL MAGAZINE.

For the convenience of those who are interested in particular genera
and would like to have the plates of such genera brought together
instead of being scattered throughout the sixty volumes of the work,
the Publishers have prepared the above Series. Each Monograph
contains the coloured plates with dissections the same as in the Magazine,
with the Descriptive and Historical Letterpress to each plate. A list
of the genera* thus prepared may be had on application. The Genera
are in alphabetical order throughout, and the species in like order
under each genus. The Monographs will be found very useful in the
class-room and for students when the introduction of the plant itself is

impracticable.

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 Jarge 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, of which Sixty
Volumes will be completed at the close of the present year (1904),
36s. each, or a complete set of the 60 vols. will be supplied for £100
cash. Subscribers may commence at any time.

The BorantcaL MaGazIng, 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 Serrus, 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, = oe

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,

Sinningia Regina resembles S. discolor in the colour of
its foliage and flowers, but is more closely allied to S. speciosa,
the wild ancestor of our modern “ Gloxinias.” Nothing is
known of its habitat, except that it was introduced from
Brazil. S. speciosa, however, grows on rocks by the sea-
shore in the State of Rio de Janeiro, according to Gardner,
Travels in Brazil, edition 2, p. 22; and Gardner’s No. 184
in the Kew Herbarium was found “on rocky places in
woods in the Rio Comprido valley” near the town of Rio
de Janeiro. SS. speciosa is recorded also from the Organ
Mountains and from Pernambuco, whilst S. discolor is known
only from the rocky banks of the river Macahé, in the State
of Rio de Janeiro, where it was collected by Riedel. See
Martius, Flora Brasiliensis, vol. viii. pars 1, pp. 388-389.

broad, convex, finely crenate, velvety with short hairs on
the upper surface and variegated on the veins, minutely

long. Flowers pendulous, 4-6 in each of the upper axils,

from 15 to 20 flowers being out at the same time on a well-

developed plant. Calyax-lobes spreading, ovate-lanceolate.
Corolla pale violet, with a pale yellowish band inside which
is spotted with purple; lobes patulous, less than $ in. long.
Stamens included; anthers connate, lobes not confluent.
Glands of the disk oblong, the two pusticous ones broader
than the others. Ovary densely villous.—T. A. SPRAGUE.

CULTIVATION.—Sinningia Regina was introduced as a
chance seedling from Brazil by Mr. de Smet-Duvivier, a
nurseryman in Ghent. He exhibited plants of it in flower
at the Ghent Quinquennial Exhibition in 19038. With the
exception of one plant which was purchased for Kew the
stock afterwards became the property of Messrs. Benary,
seed merchants, Erfurt, by whom seeds were distributed,
not only of S. Regina, but also of hybrids between it and
garden forms of S. speciosa, popularly known as “ Gloxinias.”
The hybrids which were raised by Messrs. Benary are
intermediate between the two species. For its cultivation S.
Regina requires exactly the conditions necessary for “ Gloxi-
nias” generally. It 1s very free-flowering and when well
grown isa decidedly showy plant. It seeds freely. Cuttings
of the leaves may be used for its propagation as for other
Gesneriads. It also has a permanent fleshy tuber from
which offsets may be taken—W. Warson.

An anomalous little species, which was originally figured
in the Japanese work, Somoku Zusetsu, in 1856, under the
name of Calypso borealis, a mistake which was pointed out
by Reichenbach, in 1874, when he briefly described the
plant under the name of Cypripedium debile; his descrip-
tion being based solely upon this old figure. Five years
later Franchet and Savatier described a species under the
name of C. cardiophyllum, basing it chiefly on a specimen
collected on Fudsiyama, in the province of Nippon, by
Savatier. They cited, however, the old figure above
mentioned, and a still earlier one, in the Japanese work,
Honzo Zufu, published in 1828, where it appeared without
any botanical name. A reference to the work, however,
shows a thoroughly characteristic coloured figure, with both
flowers and young fruit. It is now known from several
Japanese localities, and has also been found by Pere Farges

Maron, 1908,

in Western China, in the Tchen-kéou-tin district of the pro- _
vince of Szechuen. A single plant has also been collected _
by Mr. E. H. Wilson, at an altitude of 7,000 feet in the same —
province, though the precise locality has not been stated.

Descriprion.— Herb, terrestrial, 4—6 in. high. Stem slender
glabrous, two-leaved. Leaves broadly ovate, acute, mem
branous, 14-2 in. broad, with three to five primary nerves,
secondary veins reticulated. Scapes 3—1? in. long, arching.
Bracts linear, acute, 4-1 in. long. Pedicels over 4 in. long. |
Flowers small, with pale green sepals and petals, each
bearing a dark brown blotch at the base, forming a zon
round the column, sometimes striped with brown, and witl
a white lip streaked with purple round the mouth, Dor.
sepal ovate, acuminate, $3 in. long; lateral sepals conn
into an ovate-oblong, subobtuse limb, slightly longer than
the dorsal. Petals oblong, acuminate, as long as the dorsal
sepal. Lip ovoid-globose, nearly 4 in. long, much narrowed
at the mouth. Staminode spathulate, cucullate—R. A.
RoLrFe.

CuLtivation.—Roots of this interesting little orchi
were purchased from the Yokohama Nursery Company
They were planted in pans of leaf-mould and choppe
sphagnum and kept in an unheated frame where they flowered
in April. Although lacking the attractions of size an
colour so usual in the genus, Cypripedium debile has charms
of its own, and is quite worthy of a place among sel
“ Alpines.” It is probably sufficiently hardy to be grown
aetrgerhs in the open air, although, owing to their
pose, the flowers would be practically hidden unless the
plants were set on the high ledge of a rockery, or grown,
as at Kew, in a pan and placed whilst in flower on the stage
of a greenhouse.— W. Warson. nn

There is no more characteristic tree on the chalk hills of
west and south Britain than the Whitebeam, Pyrus Aria.
Its flowers are attractive and its fruits are especially so, but
its beauty and distinctness are never greater than when
the wind, by lifting the branches, reveals the white under-
surface of the leaves. Pyrus Aria is only surpassed in this
respect among British trees by the Abele, Populus alba.

As here, and as generally limited, Pyrus Aria includes
numerous varieties, some of which are so distinct as to be
regarded by some authors as separate species. The one repre-
sented in our plate is, perhaps, the most ornamental of
them all; its leaves, corymbs and fruits are larger than in
any other variety.

The origin of this fine variety is unknown. The state-
ment that it is a native of Nepal appears to be without

Maron, 1908,

confirmation, and probably arose from its confusion with
P. lanata, D. Don., a tree absolutely distinct. There is no
specimen in the Kew Herbarium from North India that
matches the plant now figured. It is identical with Aria
Decaisneana, Lavall., which is known to have existed in the
Arboretum of Segrez in 1858. The late Mr. Lavallée states
that his tree was known in the nurseries near Paris as the
“Sorbier du Népaul.” The most probable explanation of
its origin is that it is an improved variety raised under
cultivation. The tree from which the figure was made has
long been growing in the Kew Arboretum, where it
flowers and fruits freely almost every year. ‘The severest
cold does not hurt it.

Drscription.— Tree, ultimately 40 ft. or more high with
suberect branches. Bark at first covered with a pale tomen-
tum, finally glabrous and dark lustrous brown. Leaves 3—7
in. long, half as much wide, ovate to oval or obovate, obtuse,

Berberis acuminata was discovered by Delavay in woods
near Tcheng-fong-chau, Yunnan, in 1882. Since then it has
been collected by Dr. A. Henry and Mr. EK. H. Wilson in the
mountains of Western Hupeh, where it is, however, according
to the latter collector, who found it growing on grassy slopes
at from 5,000 to 6,000 feet above sea-level, very rare. The
specimens from which the plate was prepared were com-
municated by Messrs. James Veitch and Sons, who raised
plants from seeds obtained on their behalf by Mr. Wilson.
These plants flowered at Coombe Wood in-May, 1907. The
most nearly allied species, Berberis Wallichiana, is a native
of the Temperate Himalaya, from Nepal eastwards. It
differs mainly in having relatively broader leaves with less
tapering tips and much smaller marginal spines.

Description.—Shrub, evergreen 3-6 feet high; bark of
the young branches pale or greyish. Leaves lanceolate,
long tapering towards the tips or acuminate, spinous-serrate,

This very pretty rose was raised by Messrs. James
Veitch and Sons from seed collected by Mr. E. H. Wilson
in the Sangpan mountains, near the Tibetan frontier of
Western China, at elevations of 9500 to 11,000 ft., and the
plate was prepared from specimens communicated by that
firm, from plants which flowered at Coombe Wood in May,
1907. The most nearly allied species, R. Webbiana, is a
native of the drier regions of the western temperate
Himalaya.

Drsoription.—Shrub, densely branched, 5-10 ft. high,

Bulbophyllum FEricssoni, Rolfe in Orch. Rev. 1907, p. 233, fig. 27 (non

Kraenzl.).

This striking species has a curious history, and its identity
is by no means certain. It was exhibited by Messrs. Sander
& Sons at the Temple Show in May, 1907, under the
name of Bulbophyllum Eriessoni, and it was also figured
from a photograph ; but the Hon. Walter Rothschild, who
possesses the original type plant, did not admit the determina-
tion, and considered it to be identical with B. Binnendiykii,
J.J. Smith. A dried flower of Messrs. Sander’s plant has
been sent to Mr. Smith, who replies that his description of
B. Binnendijkii was made from a dried specimen in the
Leiden Herbarium, the colour being added from a plant that
was in cultivation at the Buitenzorg Botanic Garden some
eighteen years ago. It had been brought in by a native

Apri, 1908,

collector, probably from Mt. Salak, near Buitenzorg, and it
flowered once and then died. Cirrhopetalum leopardinum,

Teijsm. and Binn., came from Mt. Salak, and Mr. Smith says

that the two must be identical. Recently Mr. Smith

received an inflorescence of a Bulbophyllum from Soekaboemi

which he considers identical with the one preserved at

Leiden, and of which he sends a dried flower. This is

smaller than that of the plant figured, which Mr. Smith
remarks has the dimensions of his B. virescens, but he adds :—

“T am very much inclined to believe that B. virescens and

B. Eriessoni are only colour variations of the same species,

and perhaps .B. Binnendijkit will hardly be maintained as a

species.” Except in the larger dimensions, the present plant

is so similar to that previously figured in this work (t. 8088)

that it seems advisable to wait for more complete materials
before attempting to decide the question. It is unfortunate

that the type specimens are not available for comparison.

Cirrhopetalum leopardinum was originally met with on

Mt. Salak, growing on the trunks of trees in the high

forest. The altitude is not stated, but the mountain is said
to be 6970 ft. high. The specific name first employed had
to be changed because there is an earlier B. leopardinum, of
Lindley. It is curious that so striking a plant should
have so long remained practically unknown.

_ Descriprion.— Herb, epiphytical ; rhizomes strong, creep-
ing ; internodes about 6 in. long, covered with ovate-oblong
acute sheaths. Pseudobulbs oblong, about 54 in. long,
covered with spathaceous acuminate sheaths at the base,
l-leaved. Leaves petioled, broadly oblong, acute, about
1 ft. long, by 5§ in. broad; petiole 3 in. long. Scape
produced from base of pseudobulb, spreading, about 6 in.
long, with a few spathaceous, acute sheaths. Flowers
umbellate, about seven to ten, very large, light green,
spotted with dark brown, the lip paler, suffused and
marbled with reddish purple on the face. Bracts ovate,
acuminate, about 2 in. long. Pedicels nearly 1 in. long.
Dorsal sepal erect, broadly lanceolate, caudate-acuminate,
spirally twisted at the apex, 3-4 in. long; lateral sepals
spreading, oblong-lanceolate, caudate-acuminate, spirally ~
twisted at the apex, 23-34 in. long. Petals oblong-lanceolate,
spirally twisted at the apex, 14-2 in. long. Lip strongly

recurved, broadly oblong at the base, long acuminate at the
apex, nearly 1 in. long. Column short, broad, with short,
broadly oblong teeth, base prolonged into a long attenuated
foot.—R. A. RoiFs.

CuLTIvaTion.—The section of Bulbophyllum to which
B. Binnendijkii and B. Ericssoni belong does not grow well
at Kew. Messrs. Sander & Sons, St. Albans, who grew
the fine example shown at the Temple Show last year from
which the present figure was prepared, state that this species
grows well in a moist boniat house where during the
season of growth it is kept saturated and allowed a fair
amount of sunshine and air on favourable days. When at
rest only sufficient water is given to keep the soil from
becoming quite dry. In a dry atmosphere the leaves are
attacked by “spot,” especially during winter. The mixture
used is sphagnum moss with a small portion of peat fibre,
dead leaves, small crocks and silver sand. The best. plants
were grown in shallow teak baskets, suspended near the
glass in a house containing Cvelogyne pandurata, Arach-
nanthe Lowti, etc. All the Bulbophylla with thin
rhizomes and pseudobulbs and papery leaves appear to
require the conditions here given, and even then they
are not always healthy. Of the many plants of the allied
B. Eriessoni imported by Messrs. Sander & Sons it is
doubtful if a score are now alive—W. Warson.

This beautiful plant belongs to a group of very closely
allied forms which are spread all over tropical Africa. They
are unfortunately very difficult to discriminate in the dry
state unless prepared with particular care and represented
by very complete specimens; and next to nothing is known ©
about their range of variation under natural conditions.
K. Schumann, in his elaboration of the Zingiberaceae in
Engler’s Pflanzenreich, recognises three species in this
group, whilst Gagnepain in a recent paper (Bull. Soc.
Bot. France, 1905, p. 537) treats two of them, K. rosea and
K. Kirkii, as synonymous ; but if this is correct, K. Carsoni
will also have to be reduced to K. Kirkii. A fourth species
with very narrow leaves was described simultaneously
(July, 1906) by N. E. Brown as K. Cecilae and by

Apri, 1908,

Gagnepain as K. kilimanensis, from Portuguese Kast Africa.
It differs much more from the three other forms of the
group than these differ from each other, and has con-
sequently a better claim to the status of a species. Whether
the plant figured here, so far only known from a single
specimen, is actually more than astate of a very polymorphic
and plastic species can only be decided by observation in the
field and by experiment. The flowers of K. Kirkii, as
figured in B. M., t. 5994, have a slightly emarginate
labellum with a simple yellow blotch at the throat, while in
the variety elatior the labellum is bilobed with a narrow
sinus up to 15 mm. deep and a yellow blotch bordered
on both sides by a purple marking. A coloured sketch,
however, drawn on the spot by Sir John Kirk, shows the
labellum of the type 2-lobed with a simple yellow blotch.
The same marking is present in the Kew specimens of
K. Kirkii from British and German Kast Africa and of the
cultivated plant, whilst all the specimens of K. rosea and
K. Carsom have purple lateral markings as in the var.
elatior figured here.

The drawing was made from specimens presented by

Mr. H, J. Elwes of Colesborne, Cheltenham.

Description.—Herb, perennial, 12-18 in. high. Leaves
more or less oblanceolate, acuminate, long attenuated at the

As explained by Engler in his admirable monograph
published thirty-five years ago, S. Brunoniana, S. pilifera,
Hook. f. & Thom&’. and the widely distributed S. flagellaris
differ from all the other species of the section Trachyphyllum
in developing from the axils of the lower leaves thread-like
runners, which bear leaf-buds at their tips and strike root,
finally becoming independent plants, which flower the
following year. S. Brunoniana has a wide range in the
Himalaya mountains at elevations of 9000 to 13,000 ft.,
from Sikkim to Kashmir. In the Flora of British India it
is recorded from 16,000 ft., but this is probably a slip, as
none of the numerous specimens in the Herbarium are noted
from so high a level. S. pilifera, its nearest ally, differs in
having obtuse leaves and smaller flowers, the petals scarcely
exceeding the sepals; it has only been found in Sikkin, at
elevations of 14,000 to 15,000 ft. 3

Apgit, 1908,

Description.—Herb, perennial, tufted, producing numer-
ous, very slender runners, which give rise to independent
plants; with the exception of the marginal bristles of the
leaves, almost glabrous. Stems, runners, and flower-stalks
very slender, bright red; flowering-stems 2-6 in. high,
Leaves stiff, cartilaginous, narrow-lanceolate, 1—1 in. long,
sharp-pointed, margin fringed, lower ones crowded, upper
smaller, scattered, sometimes bearing bulblets in the axils.
Flower-stalks much longer than the flowers, furnished with
small inconspicuous glands. Sepals ovate, obtuse, about
yz in. long. Petals yellow, narrow, oblong, about } in.
long, obtuse. Stamens ten, shorter than the petals,
alternate ones shorter; anthers red. Capsule very small,
globose.—W. Borrine Hemstry. :

_ Cunrrvation.—Seeds of this charming little Sazifraga
were received in 1903 from the Royal Botanic Gardens,
Sibpur, Calcutta. The plants have proved hardy at Kew,
growing freely in the rock garden, but they are seen at
their best when cultivated in a pan of light stony soil in a
cold frame and placed in a greenhouse whilst in flower.
The bright crimson colour of the stems and stolons is at
least as attractive as the flowers. The stolons, which are
slender, twist about in such a manner as to produce the
effect of one of the dodders growing over a dwarf Sawifraga.
_ Another species with the same habit is S. flagellaris, but in
that the stems and stolons are green— W. Warson.

The late Mr. Maximowicz in promising a review of the
species of Aheum (Mel. Biol. xi. 686, footnote) which his
untimely death prevented him from completing, has sug-
gested as useful the subdivision of the genus into two
groups ; the Monticolae with leafy stems and membranous
leaves, and the Deserticolae, with stems leafless, or nearly so,
and firm leaves.

It is to the latter group that the species here figured
belongs. In habit and general facies it much resembles
another species of the same group, R. racemiferum, Maxim.,
from Southern Mongolia, but differs in its smaller size and

in the other particulars already noted. Another species,
ApriL, 1908.

also of this group, which has much in common with
R. inopinatum, is R. Delavayi, Franch., from Yunnan, but
in this species the leaves differ in shape, the stamens are
included and the achene-wings are thinly membranous.

Descoriprion.—fHerb, perennial; rootstock 3 in. thick.
Stem slender, red, 10 in. to a little over 1 ft. high. Leaves
firm, somewhat bullate, mostly basal and spreading, occasion-
ally one or two on the stem above the base ; nerves red
and scabrid on both sides, otherwise smooth and rather pale
green above, glaucous green beneath; truncate or cordate
at the base where 3-5-nerved; middle nerve pinnately
8—10-branched, lateral nerves 4—6-branched on the outer
side only ; rounded at the wide apex, very slightly sinuate
and throughout finely crenate, 3-6 in. long, 2-5 in. wide;
petiole flattened above, reddish, 13-4 in. long, somewhat
‘scabrid, especially on the rounded lower side. /njlorescence
paniculate ; branches simple ; raceme-like thyrses of fascicled
flowers with slender pedicels jointed below the middle ;
panicles 6-10 in. long, 23-5 in. across; branches 2-5 in.
long fastigiate in flower, in fruit forming a pyramidal mass ;
pedicels about 4 in. long. Calyx-lobes oblong, obtuse, } in.
long. Stamens usually 9, 3 outer rather longer than the
other six, all exserted. Nutlets orbicular, cordate below,
three-winged, rather bright red, nearly 4 in. across; wings
subentire with a strong nerve some distance with the edge.

CuLtivation.—R. inopinatum was raised at Kew from
seeds collected by Capt. H. J. Walton at Gyantse in
Tibet in September, 1904, during the Tibet Mission,
and presented by the Director of the Botanical Survey
of India in 1905; it flowered in a herbaceous border in
July, 1906. In this open border it has proved an attractive
little plant, the grey-green leaves forming an excellent foil
to the bright red or crimson inflorescence, which continued
at its best for several weeks. Being quite hardy and
capable of holding its own by reason of its fleshy rootstock
it ought to find favour as a border plant.—D. Prat.

Olearia ciliata inhabits deserts and sandy places at
various elevations in West Australia, South Australia,
Victoria and Tasmania, and seems to be rather polymorphic.
It reminds one in habit of an Aster or Felicia (B. M.,
t. 8049), genera which are distinguished by critical
characters, such as the degree of compression of the achenes
and the numbers of rows of pappus-bristles. Olearia is
confined to Australasia, and Felicia to Africa, whilst Aster
is widely distributed in America, Europe and Asia, with
also a few species in South Africa. :

SPRAGUE.

Cutrivation.—Kew is indebted for this plant to Sergt.
Goadby, R.E., Albany, West Australia, who whilst stationed
in that State collected specimens and seeds of many interest-
ing plants for Kew. In 1899 he forwarded seeds of this
Olearia, and a plant flowered in the Temperate House in
April last year. It forms a twiggy bush of aster-like
appearance, and is quite worthy of a place among cool
greenhouse plants. Whether it enid thrive in the open
air in any part of the British Islands remains to be tested.

It is not easy to pro Waren from ria and it has failed to
mature seeds.— W. ee

The species of Tillandsia (or Vriesia) of the group
to which 7. Blokii belongs have been much confused,
partly in consequence of authors attempting to identify
different species with the very rude, diagrammatic figure of
T. regina, Vell. (Fl. Flum., Ie. vol. iii. t. 142), partly from
the fact that Lemaire figured (IIlustr. Hort. vol. xiv. t. 516)
one species, the one generally accepted as 7. regina, and
described another, the Vriesia imperialis, Morr. (V. Glazio-
veana, Carr. in Rev. Hort. 1881, p. 50, with a coloured
plate), partly also from differences of view as to specific limits.

May, 1908,

Mr. J. G. Baker (Handbook of the Bromeliaceae, p. 22)
included V. imperialis, Morr., and V. geniculata, Wawra,
under 7. regina (V. Glazioviana, Lem. in Il. Hort. 1867,

t. 516); but Mez, with complete specimens before him, —

restored them to specific rank (DC. Monogr. Phaner. vol. %

ix. p. 615), and unravelled their very much involved
synonymy. V. imperialis differs from the others in having
secund, not distichous, white flowers, and in stature, some-
times attaining a height of 16 to 18 ft. 7. regina, as
known to us, has distichous, white bracts and flowers, only
the lower bracts being tinged with red; and the flowers
are given off at nearly right angles to the axis. But there
is a drawing in the Morren collection at Kew of a Tillandsia
having a red scape, green bracts, red inside, a green calyx and
yellow petals, which Morren himself named Vriesta gigantea,
a garden name for 7. regina.

The history of 7. Blokii is obscure and its origin appar-
ently unrecorded. A very fine plant of it was exhibited in
flower at the Ghent quinquennial meeting in 1898, but the
name of the exhibitor is not given in any of the contem-

porary papers. In the Gardeners’ Chronicle report we “

read: “The giant of the family was a huge specimen of
Tillandsia ( Vriesia) regina, shown as V. Bloku. It was as
tall as a man and in flower.” And practically the same
statement appeared in the Journal de la Société National
@ Horticulture de France. Mr. ¥.W. Moore, to whom we are
indebted for the specimen figured and for photographs of the
entire plant, writes: “I purchased the plant in question
from ]'Horticulture Colonial, Pare Leopold, Brussels, in
April, 1903, under the name of Vriesia Blokii. It was a

healthy little plant, about twelve inches high, and I was is
given to understand that it was a seedling of the original,

shown at Ghent, and quite distinct from 7. regina. It did
not flower with me until last year. The whole plant is
about 6 ft. high, and the diameter of the inflorescence from
tip to tip of the branches is 2 ft. 3 inches. I think it is a

finer plant than 7. regina, and the large bracts retain their —

colour through the fruiting stage.”

The seeds of many of the Bromeliaceae are very singular

and beautiful objects. Those of Tillandsia Bloki: are

exactly like those of Vriesia imperialis, Morr., as figured by __
Mez (FI. Bras. vol. iii, pars 3, t, 105). They are narrow, —

cylindrical or clavate bodies, tailed at the distal end and
furnished with a reversed coma at the base enveloping the
lower half of the seed. When the seed is ripe the tissue of
the tail is broken up into hair-like rows of cells similar to
the pappus of a composite. The basal coma, in the same
manner, is the result of the breaking up of the outer
integument or testa of the ovule. The integument breaks
up in a variety of ways in different species of the genus.
In T. Regnellii, Mez (FI. Bras. t. 110), for example, it breaks
up into a reversed coma at each end, the hairs of ‘which
overlap each other and completely clothe the body of the
seed. Unfortunately we did not receive the seed of
T. Blokit until after the plate was printed.

Description.— Shrub, flowering only once, though of
several—sometimes twenty—years duration. Stem very
short, unbranched. Leaves numerous, densely tufted, thick,
leathery, narrow-oblong, 24-34 ft. long, about 6 in. across
in the widest part above the broad base, tapering upwards,
abruptly long-pointed, entire, unarmed, recurved, beset
with oblong, :purple-red blotches. Inflorescence crimson,
terminal, erect, pinnately paniculate, 4 ft. 6 in. to 5 ft. long ;
scape stout, clothed with broad, sheathing bracts; lateral
branches about 14, spreading in all directions, recurved,
8 in.to 1 ft. long, ziz-zag, 10-12-flowered. Floral bracts
ovate, acute, half as long as the calyx, closely appressed,
persistent. Flowers in two rows, very shortly stalked, 3-3
in. apart, about 4 in. long. Sepals 3, lanceolate, 13-2 in.
long, acute, leathery, crimson, persistent, closely appressed
to the capsule. Petals 3, yellow, linear about 4 in. long,
acute, furnished with two small, toothed scales near the base
on the inside, marcescent. Stamens 6, equalling the petals.
Style shortly 3-lobed, a little longer than the stamens.
Capsule 3-celled, oblong, 2-24 in. long, acute, leathery,
shining. Seeds very numerous, comose at both ends, the
basal coma reversed.—W. Bortina Hemsiey.

Cuurivation.—The large Tillandsiae are handsome
stove plants. Several of them have long been conspicuous
objects in the tropical houses at Kew, and one of them,
T. regina, flowered in the Victoria house last year, where
also the gigantic Brocchinia cordylinoides flowered about

twenty years ago. They require tropical conditions, enjoying
plenty of moisture at the root, the healthiest plants at Kew
being those that stand on the tank in which the Victoria
regia is cultivated, their pots being partly in the water.
Here they receive full sunshine and as much moisture as
they would get in a tropical forest. In the palm house the
conditions are too dry for these plants. It is unfortunate
that the whole of the upper portion of the plant dies
immediately after flowering, but suckers are usually
developed from the base of the stem, and these afford means
of obtaining fresh stock. Under cultivation it takes these
big species of Tillandsia about twenty years to reach the
flowering stage.— W. Watson. |

Lemoine states that this remarkable novelty was the issue
of P. Lemoinei *‘ fantasie”; itself the result of a cross in
which P. Coulteri was one of the parents. In consequence
of there being two, or possibly three, different kinds of
Philadelphus in cultivation having red and white flowers,
considerable research was necessary to establish the identity
of the present one, and this brought to light some interesting
facts which may be put on record here. It may be premised
that the wild forms of Philadelphus are very difficult of
discrimination, and the cultivated ones still more so in
consequence of complicated intercrossing.

P. mexicanus, Schlecht., was described (Linnaea, 1839,
vol. xiii. p. 418) from specimens collected by Schiede and
others; all having large, semi-double flowers, solitary or in
threes. In the same place the author describes his P. afjinis,
from specimens in fruit, in racemes of five. Nothing is said
as to the colour of the flowers of the former, so we may assume
that they were white. The same year Hartweg collected

May, 1908.

specimens which Bentham subsequently referred (Pl. Hartw.
p- 61) to P. mexicanus. Judging from the dried s)ecimens,
the petals had a large, dark spot or centre. Hartweg also
introduced a Philadelphus with wholly white flowers from
Mexico, which Lindley figured (Bot. Reg. vol. xxviii. t. 38*)
as P. mexicanus; see also B. M. t. 7600. In 1887-8, 8.
Watson described (Proc. Am. Acad. vol. xxii. p. 472; Garden
and Forest, vol. i. p. 232, f. 40) P. Coulteri as differing
from P. mexicanus in its dense pubescence, non-acuminate
leaves, and the hairy summit of the ovary.. The flowers
are described as very fragrant and an inch or more across ;
but the colour is not given. Writing from Dublin in 1891,
the late F. W. Burbidge sent a Philadelphus to Kew, with
the following note: ‘‘Can you kindly give me the name of
the enclosed? I cannot find it in the books. It exists in
one or two old gardens here, where it is called Rose Syringa.
Its sweet fragrance and purple-centred flowers are remark-
able.” Returning to the subject in 1903 (Gard. Chron.
vol. xxxiv. p. 218), Burbidge says: “There is a variety of
P. mexicanus, called P. m. Coulteri, introduced, it is said in
Nicholson’s Supplement, as recently as 1888; but probably
this is a mistake, as the shrub has existed for many years in
old Irish gardens..... It rarely flowers except during or
after very hot summers, and it differs from all other species
or varieties of Philadelphus inasmuch as each of its four
white petals has a purplish blotch at its base which contrasts
well with the central tuft of yellow stamens.” Commenting
on this, Schneider (Ilustriertes Handbuch der Laubholz-
kunde, 1906, vol. i. p. 363) states: “There is yet another
kind in which the petals have a red eye at the base. The
shrub is of unknown origin, and was to be found in the
Botanic Garden at Leipzig, where I saw it in June, 1904.
Prof. Koehne wrote me that this obscure variety, which he
had provisionally named P. maculiflorus, was quite different
from P, Coulter.” In answer to our inquiry, Prof. Koehne
replied that he could not decide from the imperfect specimen
sent whether P. purpureo-maculatus was the same as his
P, maculiflorus.

How, when, or by whom, the name Coulteri was given to
what we may call the Irish Philadelphus, we have not been
able to ascertain ; but it is the same as Hartweg’s specimens
referred to above, and apparently different, as to the colour

of the flowers, which Nicholson describes as white, from
typical Cuulteri. Mr. W. E. Gumbleton, who grows them
side by side, informs us that Coulteri differs only in the
colour of the flowers from the form commonly cultivated
under the name of mexicanus. Neither Koehne nor Schneider
was clear as to the identity of P. Coulteri.

Drscriprion.—Shrub, 3-6 ft. high, glabrescent, very free-
flowering. Branches slender, red when young, primaries
elongated, secondaries lateral, very short, usually 1-flowered.
Leaves very shortly stalked, papery, ovate, }—2 in. long on
the flowering branches, larger on the leafy shoots, apiculate,
rounded at the base, entire or furnished with one tooth on
each side, at first sparsely furnished with appressed hairs.
Flowers solitary, terminal on very short lateral shoots of the
main, long branches. Calyx lobes 4, ovate, about } in. long,
acuminate, 3-nerved, puberulous outside, tomentose inside,
white. Petals 4, ovate-rotundate, 4-2 in. long, glabrous or
furnished with a few scattered hairs on the outside, white
with a bright purple-red base. Stamens very numerous;
anthers yellow. Styles and top of ovary glabrous; stigmas
capitate—W. Borrina Hems.ey.

Cuitivation.—The plant here figured is a very distinct
addition to the hardy sorts of Philadelphus. The fine
purple blotch which stains the base of each petal gives a
colour effect which is lacking in the other hardy species, all
of which have pure or nearly pure white flowers. Judging
by the young plants in the Kew collection it appears to be
of low or medium habit. A mode of cultivation which
answers exceedingly well for Philadelphus Lemoinei at Kew
may be adopted for this plant also. This is to cut away the
shoots that have flowered as soon as the blossoms are over,
thus leaving behind nothing but the young growths of the
current year. These grow quickly and make long flowering
shoots for the following year, to be cut away in their turn.
Propagation is most readily effected by cuttings made of the
young shoots whilst they are still in a semi-herbaceous
condition. Placed in a brisk bottom-heat they strike root
in a few days. The plant from which the figure was
prepared was purchased from Messrs. Veitch in 1905,—

The Annales de Flore et de Pomone, in which Puya
(Piteairnia) violacea was first published, are not in the
Kew library, but from an extract from the same in Otto and
Dietrich’s Allgemeine Gartenzeitung, 1847, vol. xv. p. 299, it
appears that Puya violacea was first raised from seed in the
Jardin des Plantes, Paris, in 1833 and flowered for the first
time at Neuilly in 1847, a long time to wait for flowers,
though they are brilliant when they do appear. But many
Bromeliaceae flower only once or at distant intervals. The
conflicting views of different writers on some of the genera
of the Bromeliaceae are somewhat puzzling. Bentham and
Hooker retain Pitcairnia, Puya (including Pourretia) and

May, 1908.

Tillandsia (including Vriesia). Baker's Jimitations are
much the same; but Mez keeps up both Tillandsia and
Vriesia ; the latter having free petals ; the former connate or
closely conglutinated petals. Apart from this, a very large
proportion of the Bromeliaceae in cultivation have names
under at least two genera. :

Mez has also revised the synonymy of som, of the allied
species of Puya. Lindley adopted the name caerulea for
the plant he figured and described in the place cited above,
believing it to be the same as that mentioned in Miers’s
Travels in Chile and La Plata, vol. ii. p. 531, as Pourretia
caerulea; but Mez refers the latter to Pitcairnia alpestris,
Poepp., to which he also refers Puya Wahytei, Hook. f.

he regards as the same as Pitcairnia caerulea, Lindl.

He distinguishes Puya, Molina (including Pourretia,
Ruiz and Pavon), from Pitcairnia, L’heritier, by the com-
pletely superior ovary, and he divides Puya into three
subgenera: Hupuya, Pitcairniopsis and Pourretia.

Dersoription.—Shrub, flowering more than once, including
inflorescence about 3 ft. high. Stem short; branches few.
Leaves numerous, crowded, stiff, linear, largest 20 in. long,
tapering upwards and very narrow, margin furnished with
small prickles, }-3 in. apart and directed upwards, finely
striated, underside clothed with microscopic stellate scales.
Inflorescence terminal, erect ; pinnately paniculate, 18-20 in.
high ; scape rather slender, clothed with brown linear bracts
1-2 in. long, which shrivel and persist; lateral branches
about twelve, spreading in all directions, deflected, 5-8 in.
long, 20-—25-flowered. Flowers spirally arranged, shortly
stalked, 4-3 in. apart. Sepals 3, green, lanceolate, 1-1} in.
long, acute, persistent. Petals 3, deep violet, oblong-spathu-
late, about 2} in. long, obtuse, shortly recurved, furnished
with two scales inside near the base. Stamens 6, nearly

equalling the petals; anthers orange. Style included.—
W. Borrine Hemstey.

Cuitivation.—Puya and that section of Piteairnia which
Mr. Baker separated under the name of Puyopsis are all
hard prickly-leaved plants which appear to be happiest
when cultivated under the same condition as Cacti, Agave,

etc. They do not suffer if kept dry at the root, and the
poorer the soil the healthier they are; but they must be in
a position where they can get plenty of sunlight and air.
The handsomest of them is P. caerulea, which has flowered
several times at Kew. Between this and P. violacea there
is a close resemblance, but the flowers of the latter are
smaller. The latter flowered on the rockery at the south
end of the Mexican House in June last year, where it has
stood since the house was built, in 1897. The plant was
presented to Kew in 1879 by the late Mr. J. Anderson
Henry, Hay Lodge, Trinity, Edinburgh, who had it under
the name of Puya paniculata.—W. Wa'rson.

The genus Liparis is not often met with outside Botanic
Gardens, as few of the species can be called showy. There
are, however, a few exceptions, and among them-the subject
of the present plate. L. tabularis flowered in the collection
of Mr. H. T. Pitt, Rosslyn, Stamford Hill, in April, 1906,
and was exhibited at a meeting of the Royal Horticultural
Society. Shortly afterwards a plant was presented to Kew,
where it flowered in the following June, when the annexed
drawing was made. After some correspondence it was
ascertained that it had been sent by Mr. O. Curtis, of the
Forest Department, Penang, to Mr. H. A. Tracy, of
Twickenham, so that it is probably a native of the region
mentioned. It is most nearly related to the Formosan
L. macrantha, Rolfe, from which, however, it differs in
having an orbicular lip, with regularly radiating veins. Its
large reddish purple flowers with strongly denticulate lip
render it very attractive.

Liparis is a large and widely diffused genus, being found
throughout the tropics, and in subtropical, and even

temperate regions; a single species, LZ. Loeselii, Rich.,
being represented in a few British localities. The species
are most numerous in the mountains of India and the
Malayan Archipelago. Four other species have been figured
in this work, namely :—L. tricallosa, Reichb. f. (t. 7804),
a large-flowered Malayan species, closely striped with purple
on the lip; ZL. atropurpurea, Wight (t. 5529), a native of
South India, having dark purple flowers; LZ. Walkeriae,
Graham (t. 3770), a Ceylon species with small green and
purple flowers; and ZL. foliosa, Lindl. (t. 2709), a species
with small green flowers, now known to be a form of the
Australian L. reflexa, Lindl.

Descriprion.—Pseudobulbs narrowly conical, 3—5 in. long,

The home of this dwarf cherry is in the mountains of
Northern and Western China, from Mandshuria to Szechuen.
According to Bretschneider it is much cultivated at Peking
for its edible, cherry-like fruits. It became, however, first
known from Japan, where it is also frequently grown in
gardens. Specimens of it were collected by Moorcroft in
Ladakh and by T. Thomson in the valley of Kashmir. The
former was named Cerasus tomentosa by Wallich in his
Catalogue. It is very probable that those specimens were
also taken from cultivated plants.

hairy in the upper part. J’ruit a small, sparingly hairy
cherry, 4 in. long, bright red.—Orro Srapr.

Cutrrvation.— Prunus tomentosa is one of the earliest-
flowering species of its genus. It is usually in full blossom
during March, and is one of the most attractive of hardy
shrubs at that season. The species is not common in
gardens, but is well worth cultivating for its early flowers
and its neat habit. It makes a low, rounded, dense bush,
somewhat wider than it is high. Its only defect as a garden
shrub is that its beauty is rather fleeting. The petals are
fragile and unable to withstand the pelting showers which
frequently prevail in late March and early April. The
plants at Kew occasionally ripen a few fruits, but these are
too infrequent to afford a reliable means of increase. The

species can, however, be propagated by means of cuttings.
The plant from which our figure was made has long been
in the collection at Kew.—W. J. Bean.

This fine screw pine was introduced from Singapore by a
Mr. Porte in 1865, and flowered in the Jardin des Plantes in
Paris for the first time in 1868. It was a male plant, like

the Kew specimen from which the accompanying figure

was drawn. According to Mr. Ridley, who gave a complete
description of it in the wild state, it is endemic in the
Southern part of the Malay Peninsula (Singapore and
Johore), where it grows in dense forests. The fruit is
according to him eatable and tastes like a pineapple.

DescripTion.—Stem 7 or 8 ft. high in the wild state,
simple or at least not branched at the top, 4 in. across;
aérial roots 2 in. thick. eaves numerous, their bases
persistent ; blades linear, gradually tapering into a long
slender acumen, sometimes 8 ft. long and 4 in. broad,
coriaceous, dark green, tinged with copper-red or the young

ones purple, marginal spines small, curved, with brown or
Jung, 1908,

purple tips. Male panicle 2 or more feet long; bracts
lanceolate, acuminate, the lower 14 by 3 in., the uppermost
6 in. by 1 in., margins spinulous; spikes cylindric, dense,
6-8 in. long, 2 in. in diameter. laments united almost to
their tips into columnar fascicles, } in. thick; anthers 75 in.
long, apiculate, dehiscing all along. Female spike solitary ;
in fruit cylindric, 1 ft. long, orange-coloured, fleshy.
Drupes angular, } in. across, with a truncate, flat top.—
Orro Srapr.

CuLtivation.—The plant figured was received at Kew
in 1905 from the Botanic Gardens, Singapore. It was
evidently a seedling. It grew very rapidly under tropical
treatment, as all the Pandani do, and flowered in April last
year. The Kew collection of Pandanz is rich in species, and
some of them flower fairly regularly. In the Palm-house
they grow to a large size, with stems as much as 20 ft.
high, bearing enormous crowns of leaves. They are easily
kept in health, enjoying great heat and plenty of water,
whilst they are not particular in regard to soil. In a wild
state they grow most luxuriantly in swamps or by the
side of rivers, and they are equally happy when treated as
sub-aquatics under cultivation. There is a fine collection of
them in the Botanical Garden at Brussels, where they are
grown in the same tank as the Victoria regia. Some of the
species are grown as pot plants for decorative purposes,
particularly P. Veitehii, P. Sanderi, P. inermis and P.
utilis. Owing to their being dioecious they have never
-- ripened fruits at Kew, but they are easily multiplied by
means of offsets which are freely developed by many of the
species, and they strike root readily —W. Warson.

Turezaninow, in his original description of this species,
describes the inflorescence as being in lateral corymbs, and
when correcting himself, Flora Baic.-Dah., says, “racemi. . .
axillares, multiflori.” The racemes are however distinctly
terminal, as stated by Maximowicz in his classification of the ©
Oriental Rhododendrons.

In distribution the species extends from Manchuria in the
north, to Kansuh in the west, and Hupeh in the south, but it
is only rarely met with, and is noted by all the collectors as
being found only on the very tops of the mountains. In

its native habitat, Franchet states that it flowers in June
and July.

Description.— Shrub of small dimensions. Branches
pubescent and sparingly glandular-scaly when young,
glabrous when old. Leaves oblanceolate, obtuse to subacute,
cuneate at the base, glabrous and pitted above, densel

scaly below, 1-2 in, long, 33-4 in. broad; petioles about

| Curtivation.—The plant figured was grown in the
garden of J, ©. Williams, Esq., Caerhays Castle, Gorran,
Cornwall, a most enthusiastic collector and cultivator of
Rhododendra, and was presented to Kew through Messrs.
James Veitch & Sons, by whom it was introduced into culti-
vation through their collector, Mr. Wilson. He described it
as a bush from 4 to 8 ft. high, with white flowers, growing
at from 5,500 to 8,000 ft. At Coombe Wood this plant has
proved hardy, and Mr. Harrow, Messrs. Veitch & Sons’
manager there, says it appears to prefer a rather shaded
position and a light loam rather than peat. It is, he says,
very free-flowering, small plants of it being now covered
with flower buds. The plant first flowered at Coombe
Wood in May, 1904. In Mr. Williams’s garden also the
flowers were developed in May.— W. Warson. |

The remarkable species here figured is a native of
Annam, where it was discovered by Mr. W. Micholitz,
when collecting for Messrs. Sander & Sons. Living plants
were sent home, one of which flowered at Kew in September,
1907, when the species was described under the name of
Cirrhopetalum fascinator, Rolfe. The genus Cirrhopetalum,
however, merges so imperceptibly into Bulbophyllum that
the two are now regarded as indistinguishable, hence the
adoption here of the older generic name. Bulbophyllum
ascinator is nearly allied to the Himalayan B. appendiculatum,
Rolfe (Cirrhopetalum ornatissimum, King & Pantl. in Ann,
R. Bot. Gard. Calc. vol. viii. p. 95, t. 133, not of Reichb. f.),
but has much larger flowers, with various structural
differences. It is a member of a smal] group characterised
by its solitary-flowered scapes, containing the following
additional species :— Bulbophyllum merquense, Par. & Reichb.
f., B. lasioglossum, Par, & Reichb. f., B. antenniferum,

Jung, 1908,

Reichb. f., B. mazillare, Reichb. f., B. breviscapum, Rid].
(Cirrhopetalum breviscapum, Rolfe, Bot. Mag. t. 8033), and
two or three imperfectly known Malayan species. All of
these were formerly considered to be anomalous species of
Cirrhopetalum, having the floral structure though not the
remarkable umbellate inflorescence of the genus. The
elongation of, and frequently the union of the lateral
sepals constituted the most marked character of Cirrho-
petalum, and it is unfortunate that the occurrence of
species of intermediate character should render it un-
tenable.

Description.—Lpiphyte with stout creeping rhizome.
Pseudobulbs approximate, ovoid-oblong, obscurely tetra-
gonous, shining, 3-1 in. long, l-leaved. Leaves sessile,
elliptical-oblong, obtuse, coriaceous, about 2 in. long, over
1 in. broad. Scape suberect, about 4 in. long, 1-flowered.
Bracts spathaceous, acute, 1 in. long. lowers large, pale
green with crimson markings. Dorsal sepal ovate, acumi-
nate, about 14 in. long, with crimson filiform appendages
above the apex, ciliate towards the base; lateral sepals”
united, oblong-lanceolate below, then prolonged into long
caudate appendages, about 7 in. long, the basal part
coriaceous, verrucose, with revolute margin. Petals falcate-
oblong, subacute, under 3} in. long, the margin and apex
bearing numerous crimson filiform appendages. Lip
recurved, ovate-oblong, subobtuse, channelled, bicarinate,
with the keels and margins puberulous. Column broad,
4 in. long, with acute margins and acute slightly tridenticu-
late teeth—R. A. Ror.

CuLtivation.—This is one of the many introductions for
which we are indebted to Messrs. Sander & Sons, St. Albans,
who presented a plant of it to Kew in 1905, which flowered
for the first time in September, 1907. The genus Bulbo-
phyllum is popular with orchid fanciers in this country, owing
no doubt to the quaintness of form and beautiful coloration
in the flowers of many of the species. They are tropical or
subtropical, and with few exceptions they enjoy the con-
ditions of a moist stove all the year round with plenty of
water about their roots whilst growth is being made and
very little during their resting season, generally the winter,

They may be grown either in shallow teak baskets suspended
near the roof-glass in a shaded house or on blocks of tree
fern stem, and what little compost they require about
their roots should be sphagnum moss and peat fibre.—
W. Watson.

Chirita barbata is like C. hamosa in having the peduncles
united with the petioles, so that the flowers seem to spring
from the latter, but there the resemblance ends. The two
species differ in the leaves, in the size and shape of the calyx
and corolla, and. in the anthers, which are very woolly in
C. barbata and glabrous in C. hamosa.

C. barbata was brought into commerce as C. hamosa in
1895 by Mr. J. Sallier of Neuilly, Seine, France, who in
reply to an inquiry has: courteously given us all the
information at his disposal. He obtained the species from
the late Prof. H. Baillon, who informed him that it had
been introduced by seed from the “mountains of India.”
There are no wild specimens of C. barbata in the Kew
Herbarium, and it seems probable that it is a native of one

of the French possessions in the East Indies. C. hamosa

and other species occur on damp rocks by the side of
streams,

Drscription.— Herb, perennial. Siem erect, 2 ft. high,
pubescent. Leaves ovate-oblong, 3-6 in. long, 1-24 in,
broad, apex subacute, recurved, base subcordate, villous-
pubescent on both surfaces, nerves 8-10 on each side of the
midrib, impressed on the upper surface, prominent on the
lower; petioles 4-1 in. long. Peduneles connate with the
petioles; pedicels free from one another, 4-8 on each
petiole. ee deeply divided, segments lanceolate-oblong,
about 4 in. long. Corolla funnel-shaped, ventricose, bluish
hlae with a yellow band in front; tube 1 in. or more
long; lobes slightly spreading. Stamens 2, anterior;
anthers parallel, slightly depressed at the apex and joined to
one another by a common appendage, connectives facing
outwards, Staminodes 3, filiform. Disk annular. Ovary
densely villous; style exceeding the stamens. Capsule
(unripe) 2 in. long, villous-pubescent.—T. A. SPRAGUE.

CuLtivation.—Chirita barbata has been cultivated at
Kew for the last twelve years, being treated as a biennial
and grown along with such plants as Sinningia, Achimenes,
ete. The seeds, which are matured freely by cultivated
plants, are sown in early spring, and under liberal treatment
the seedlings grow to a good size by the autumn. Leaf-
cuttings also may be used for propagation as with Sinningiae
and other Gesneraceae. They cee freely the following
spring, well-grown plants being quite attractive when in
full flower. As a garden plant C. barbata is less beautiful
than C. Moonii from Ceylon, which grows a yard high and
has purplish flowers, 4 in. across, freely produced in the
axils of the whorled ovate-lanceolate leaves; nor is it as
charming as the Chinese C. depressa, which has the habit of
a Sinningia and long-tubed blue flowers nestling among the

fleshy leaves. Both of these plants are grown in the stoves
at Kew.—W. Warson.

‘he species here figured is confined to the Lepontine
Alps in the vicinity of Lake Como on the borders of Italy
and Switzerland, where it grows on mountain sides at high
altitudes. It forms by itself the subsection Emeroides,
Briquet, characterised by the solitary or geminate, axillary
flowers, just as G. nigricans is the solitary species of the
subsection Eulembotropis, Briquet, which has the flowers
arranged in terminal leafless racemes.

The limits of Genista and Cytisus have been variously
drawn by botanists, and some, including Baillon, combined
them. Briquet, however, in his Les Cytises des Alpes
Maritimes, places the species with a well-developed strophiole
in Cytisus, and those with a rudimentary strophiole, or
none, in Genista.

Jung, 1908.

Description.—Shrub about 3 ft. high. Young branches
quadrangular, sparingly pilose. Leaves trifoliolate ; petioles
1-1} in. long; leaflets subsessile, obovate or oblong,
about 4 in. long, 3-4 in. broad, rounded or slightl
emarginate at the apex, glabrescent above, thinly clothed
with silky hairs beneath ; lateral nerves indistinet. Flowers
yellow, axillary, solitary or two together ; pedicels equalling
the petioles. Calyx subcampanulate, } in. long, shortly
two-lipped, lips shorter than the tube, sparingly villous
outside; upper lip bidentate; lower tridentate. Standard
somewhat rounded, many-veined, scarcely 4 in. across, claw
1 in. long. Wing petals obovate, 3 in. long, + in. broad,
7-nerved, claw } in. long. Keel petals 4 in. long, claw } in.
long. Staminal tube glabrous, $ in. long; anthers oblong.
Ovary glabrous; style } in. long, stigma minute. Pod
1-13 in. long, 3-4 in. broad, glabrous. Seeds 5 or 6, reni-
form, without a strophiole——J. Hurcuinson.

Cunrivation.—Although Cytisus glabrescens is not a 2
newly discovered plant, it has only appeared in cultivation
during comparatively recent years. The plant from which

the accompanying plate was prepared was obtained for the

Kew collection in 1896, from Mr. Spith of Berlin. It has
proved to be quite hardy and one of the most attractive of
the dwarfer Brooms, flowering in May, and thriving well in
a light loamy soil, in a position exposed to full sunshine.
It is of a close, dense habit, and isadmirably adapted for the _
Rock Garden or for any position where it is not in danger
of being overgrown by plants of stronger habit, The —
original plant at Kew, after twelve years, is still not more
than 18 in. high. It can be increased by cuttings,
dibbled in sandy soil under a cloche during August—

eum fig. suppl., non Champ.

This and the two species with which it is compared in
the above description are very closely allied in structure.
Indeed B. Bowringiana and B. laciniata have been treated
as varieties of one species by De Candolle and others; but
the plants cultivated and figured in this Magazine under
these names are quite distinct. The cultivated B. cathayana
is exactly the same as dried specimens in the Kew Herbarium,
bearing the numbers 9198 and 13516, collected by Dr. A.
Henry near Mengtze, Yunnan, at an elevation of 5,000 ft.

Drsoriprion.—Herb, 2-3 ft. high, with fleshy stems and
leaves, clothed with long, crimson, soft, scurfy hairs,

interspersed on the branches with a few white ones.
Jury, 1908,

Leaves long-stalked; blade obliquely cordate, as much as
10 in. long, more or less distinctly lobed, minutely toothed,
lateral lobes and tip sharp-pointed, basal lobes rounded,
crimson below, green above except the crimson nerves, with
a paler zone; stalks as much as 6-8 in. long; stipules
narrow, pointed, about an inch long. Clusters axillary,
8-10-flowered, pendulous, shorter than the leaves; bracts
small, inconspicuous. owers coarsely hairy, unisexual in
the same clusters, vermilion, 14-12 in. across. Male flowers:

rianth of 4 petaloid leaves; 2 exterior nearly oval, about
bin. long ; 2 interior narrow-ovate, less than 4 in. long;
stamens numerous, in a stalked head. Female flowers:
perianth nearly equally 5-leaved; leaves oblong-ovate ;
styles crested. Capsule hairy, pendulous from a sharp bend
at the top of the stalk, unequally 3-winged, wings rounded,
larger one 2 in. long, smaller } in. long.—W. Borrine
HEMSLEY.

Cuttivation.— Begonia cathayana was introduced into
cultivation by Mr. A. K. Bully of Ness, Neston, by means
of seeds collected for him in China by Dr. A. Henry. The
stock passed into the hands of Messrs. F. Sander and Sons,
St. Albans, from whom the plant figured was obtained for
Kew. Messrs. Sander and Sons have raised a batch of
hybrids from B. cathayana and B. Rex which are remarkable
for richness of leaf coloration, B. cathayana is a handsome
stove plant. Under liberal treatment it develops numerous
stems 18 in, high, bearing in September numerous clusters
of flowers. It ripens seeds under cultivation. Cuttings of
the stems and leaves root freely —W. Watson.

adnata.—Coelogyne sulphurea, Hook. f. Fl. Brit. Ind. vol. v. p. 833 (non
Reichb. f.); Ridl. Mater, Fl. Malay Penins. part 1, p. 182.

Two quite distinct species have been confused under
the name Coelogyne sulphurea. The original was based
upon Chelonanthera sulphurea, Blume, Bijdr. p. 283, a
native of Java, but Sir J. D. Hooker afterwards included
under the name a Perak plant which had been collected by
Scortechini and Wray, and in this he was followed by Mr.
H. N. Ridley, the latter pointing out that in some respects
the species was almost intermediate between the genera
Coelogyne and Pholidota. The late Dr. E. Pfitzer, in mono-
graphing the Coelogyne group, proposed several new genera,
and among them Chelonistele, in Engl. Pflanzenreich, Orch.
Coelog. p. 136, to include Coelogyne sulphurea, Reich. f.,
and four other species, Chelonanthera being retained for
Blume’s original Chelonanthera gibbosa and one other: but

the differences between them are so slight that the old name
Juty, 1908.

Coelogyne is here preferred. Should Chelonistele be
ultimately retained, however, the name Chelonistele perak-
ensis will apply to the present plant. - Pfitzer does not
cite either the Perak plant or the Flora of British India
under his Chelonistele sulphurea, so probably did not include
it, but the only other species with which it could be con-
fused are Coelogyne tenuiflora, Ridl., a native of Borneo, and
C. lurida, L. Lind. and Cogn., whose habitat is not recorded.
Both are figured, however, and as Ridley treats the former
as distinct, while the latter has the bracts and side lobes of
the lip relatively twice as broad, the only possible course is
to consider the present one as distinct.

The Javan Coelogyne sulphurea, Reichb. f., has long been
cultivated at Kew, and in 1903 the Malayan plant was
received fron: the Royal Botanic Garden, Glasnevin, under
the same name. The two species flowered together during
January of the present year, thus affording an opportunity
of clearing up the confusion between them.

Descriprion.—Epiphyte, 1-1} ft. high. Pseudobulbs
approximate, ovoid-oblong, 14-2 in. long, 1-leaved.
Leaves long-petioled, oblong-lanceolate or narrowly ellipti-
cal, subacute, coriaceous, 5—7 in. long; petiole 2-4 in. long.
Scapes erect, borne with the young growths from the base
of the old pseudobulbs, $-2 ft. high, the basal half covered

Herba acaulis. Folia pluria, rosulata, patula vel ascendentia, ovata, elliptica,
vel obovata, apice subobtusa, basi rotundata vel plus minusve angustata,
7-15 cm. longa, 4-7 cm..lata, crenato-serrata, utrinque subtus longius

staminodia tria, posticum lateralibus minus. Discus annularis, crenatus,
vix 1-5 mm. altus. Ovarium elongatum, ut stylus glanduloso-pubescens.

There are no authentically named specimens of Didymo-
carpus cyanea in the Kew Herbarium, but the plant figured
agrees so well with the original description, except as
regards the scapes, which are described as 2-flowered, that
there is little doubt as to its belonging to that species.

D. cyanea was collected at Kasum, in the Siamese part of
the Malay Peninsula, by Mr. C. Curtis, Superintendent of
the Botanic Gardens, Penang. .

Ridley remarks that the number of Didymocarpi in the
Siamese-Malayan region seems endless, every district sup-
plying one or more new kinds; and the same holds good
for many other genera of Gesneraceae in different parts of
the world, as for example the Tropical American genus
Columnea, of which more than twenty species have been
described from Costa Rica alone.

Description.—Herb, stemless. Leaves in a_ rosette,
Juxy, 1908,

spreading or ascending, ovate, elliptic or obovate, apex
rather obtuse, base rounded or narrowed, 3-6 in. long, 14-3
in. broad, crenate-serrate, softly pubescent, lateral nerves
7-8 on each side of the midrib, impressed above, prominent
below; petioles 3-24 in. long. Scapes 2 or more, 4—5-.
flowered ; peduncles villous-pubescent, 24 in. long. Calya
divided to the base; segments suberect, linear-subulate,
4 in. long, pubescent outside. Corolla deep blue, trumpet-
shaped, about 14 in. long, lobes patulous. Stamens 2 only
perfect, anticous; filaments inserted below the middle of
the tube, broadened towards the middle, white; anthers
connate; staminodes 3, the posticous smaller than the
lateral ones. Disk annular. Ovary elongated, glandular-
pubescent.—T. A. Spracur.

Cuntivation.—Didymocarpus cyanea was first grown at
Kew in 1902, when seeds of it were received from Mr.
C. Curtis, Superintendent, Botanic Gardens, Penang. It
has also been received from Professor Costantin, Jardin des -
Plantes, Paris. It flowers in the autumn, the pretty dark
blue flowers opening in slow succession in a tropical house,
where it receives the same treatment as Sinningia and the
Streptocarpi. Although the Malayan species of this genus
have been again and again tried as garden plants at Kew,
they have never been a success. Probably they require to
be treated as annuals, and as they do not mature seeds
under cultivation, they soon die out. They are quite as
pretty as their allies the Streptocarpi, which were at one
time generically united with them, S. Reaii having been
figured in this work, t. 3005 (1830), as Didymocarpus Rezii,
while D. malayana, B. M. t. 7526, has all the appearance of
a yellow flowered Streptocarpus.—W. Watson.

About fifteen species of this exclusively Australasian
genus are now cultivated in this country, and of these the
plant here figured is probably the most graceful. It is
widely spread in New South Wales, Victoria, Tasmania
and South Australia, and ts frequently found growing in
waste places. :

Bentham, in the Flora Australiensis, distinguishes two
forms, a. microphylla and b. communis, and whether these be
separable as species it is difficult to decide without a know-
ledge of the plants in the wild state. Those grown at Kew
are strikingly uniform in habit, as well as in the shape of
the leaves and size of the flowers, but the dried specimens
preserved in the Herbarium show great variation.

more or less scabrous, pubescent branches. Leaves linear-

branches papillose. Achenes +5 in. long, slightly com-
pressed, sparsely pilose ; setae of the pappus 4/5 in. long.—
J. Hurcninson.

CuitivaTion.— Olearia ramulosa is an old garden plant
which has been grown at Kew many years for greenhouse
decoration. It forms an elegant shrub a yard or so high,
and the long freely branched shoots when clothed in early
spring with white aster-like flowers are particularly orna-
mental. Grown in pots out of doors during summer and
wintered in a greenhouse it is easily kept in health, and if
afforded a little extra heat in December it will flower
readily some weeks earlier than its usual time. Like all
the species of Olearia it is easily propagated by means of
cuttings. In the South of Engiand and Ireland it may be
seen here and there treated as a wall shrub, the main shoots
being trained against the wall, and from these there is
annually produced a thick crop of long branchlets which
flower freely in spring. After flowering, these shoots are
spurred. back.— W. Warson.

setosum, stylo 3-3°5 em. longo glabro.—R. Farrerae, var. Weyrichii, Diels,
in Engl. Bot. Jahrb. vol. xxix. p. 513.

Rhododendron Mariesii is very closely allied to R. rhom-
bicum, Miq., figured at tab. 6972 of this Magazine, but the
two species inhabit widely distant regions. R&R. rhombicum,
which is distinguished from the species here figured by
having pure lilac flowers without any spots, ovate leaves,
and hairy branches, has so far only been recorded from
Japan, where it grows in mountain forests; whereas
. Mariesii is confined to Central China.

According to Wilson, R. Mariesii, R. indicum and R.
sinense are the only species of Rhododendron which occur
below 4,000 ft. in Central China. Between this altitude
and 15,000 ft. other species are found in great abundance.

Descriprion.—Shrub, 3-6 ft. high; branches shining,
glabrous. Leaves ovate-lanceolate, acute, 2-23 in. long,
#-13 in. broad, more or less wedge-shaped at the base, in

Juy, 1908.

the young state with long silky hairs on the upper surface,
sparingly pubescent below, at length becoming glabrous ;
lateral nerves 3—4, suberect at the base, more spreading in
the upper part, raised below; veins closely reticulated ;
petioles 4-4 in. long. Buds ovoid; scales broadly ovate or
oblong, apiculate, pubescent outside towards the apex.
Flowers usually in pairs, pale pink with purple spots on the
upper segments; pedicels erect, 4-1} in. long, hispid.
Calyx annular, densely setose. Corolla deeply 5-lobed,
glabrous on both sides; tube 4-1} in. long, lobes 4-2 in.
long, spreading, elliptic, obtuse. Stamens 10, shortly
exserted ; filaments glabrous; anthers jy in. long. Ovary
ovoid, densely setose; style 14-14 in. long, glabrous.—
J. HurcHinson.

Cuntivation.—Rhedodendron Mariesii was raised from —
seeds received at Kew in 1886 from Dr. Henry when at
Ichang. The plants have received protection; that figured _
having flowered in the Himalayan House in April, 1907. _
The deciduous Lhododendra from China to which this species _
belongs are handsome spring-flowering shrubs, the best
known of these, FR. sinense, being one of the most popular of
garden plants. It is probable that R. Mariesii will bear
the temperature of the warmer parts of the British Islands; _
it ought to be quite at home in Devon and South Cornwall. _

There has been considerable difference of opinion amongst
botanists from time to time as to whether Caesalpinia

japonica should be united with C. sepiaria or not, but for
- gardening purposes it is certainly distinct. The racemes
are much laxer in C. japonica and the pedicels are longer,
whilst the uppermost petal has red markings, which
apparently do not occur in C. sepiaria.

The colouring of the corolla recalls that of C. vernalis,
B. M. t. 8132, which is, however, much less showy.

Avaust, 1908.

Descrrerion.— Shrub, about 6 ft. high, | straggling.
Branches long, armed with recurved prickles. Leaves
bipinnate, with 3-8 pairs of pinnae; rhachis furnished with
two recurved prickles on the lower surface and one straight
ascending prickle on the upper surface at each node, inter-
nodes of rhachis armed or unarmed; leaflets 5-10 pairs,
elliptic-oblong or obovate-oblong, rounded at the apex,
rounded or obtuse at the base, 3-3 in. long, 4—;°, in. broad,
densely dotted with pellucid glands, glabrous on the upper
surface, puberulous on the lower. Stipules small and
caducous. tacemes about 9 in. long, shortly peduncled,
lax-flowered; rhachis usually glabrous; pedicels slender,
over lin. long. Flowers about 30. Calyx-tube very short;
lobes ovate-oblong, rounded, about } in. long, finally
reflexed. Petals lemon-yellow, obovate, the uppermost one
smaller than the others, striped with red, and provided with
two auricles above the short claw. Stamens 10, red, alter-
nately shorter; filaments densely villous below. Ovary
oblong, compressed, hardly 4 in. long; style tubular, trun-
cate, fringed at the apex, glabrous elsewhere. Legume
oblong, straight, about 3 in. long, with a spine-like cusp at
the apex of the ventral suture, and a prominent dorsal keel. —
Seeds 6-9, oblong, smooth.—T’. A. SPRAGUE.

Cunrivation.—Caesalpinia japonica first flowered in
England in 1887 in the Coombe Wood nursery of Messrs. J.
Veitch & Sons, by whom the plant had been introduced from
Japan a few years previously. It is hardy only in sheltered
positions in the south of England, the plant from which the
present plate was prepared being one of a group established
in a recess under the south wall of the Temperate House at
Kew, where it has grown practically uninjured by frost for
about five years. In some Cornish and Irish gardens it is
quite at home, one of the largest specimens, which flowers
freely every year, being in the garden of Lord Barrymore
at Fota, near Cork. Whilst the species generally are
strong climbers, this forms a somewhat straggling deciduous
shrub, the shoots being comparatively short; the flowers

are borne in terminal racemes on the young growths in
June.—W. Warson.

Indigofera hebepetala is widely distributed in the North-
Western Himalaya, at elevations of 6,000-8,000 ft., from
Hazara, where it was first collected by Dr. J. L. Stewart,
and Kashmir, where it was originally obtained by Mr. V.
Jacquemont, to Kamaon, where it was first seen by Dr. T.
Thomson. So far it has not been recorded from Nepal, but
it reappears in Inner Sikkim where it was first found by
Sir J. D. Hooker in the Lachen Valley at 7,000 ft. The
species is very closely allied to J. atropurpurea, Ham., which
is met with as a rule at slightly lower elevations and has a
somewhat wider distribution, since it extends to Indo-China
and is believed to occur alsoin Southern China. J. atropur-

Avaust, 1908,

purea, figured in this work at t. 3065, differs most markedly
from J. hebepetala in the darker colour of its flowers, in the
narrower and smaller bracts, and in the number of its leaflets,
never fewer than 11, usually 13-17; in J. hebepetala the
maximum number, very rarely met with, is 11, the usual
number being 5-7, though leaves with 9 leaflets are not
uncommon. Though long ago segregated by Mr. Bentham,
no description of this species was published till the Indian
Leguminosae were taken up in the second volume of the
Flora of British India. Owing to the inclusion in the
species of what was then taken for a sub-alpine form with
smaller leaflets, but is now known to belong to another
species, the number of leaflets in the original description is
given as 13-17, and the range of elevation is stated to be
from 6,000 to 15,000 ft. The actual number of leaflets is,
however, as stated above, 5-11, and the known range of
elevation of the species is from 6,000-8,000 ft.

Description.—Shrub, of considerable size. Branchlets at
first sparingly beset with adpressed hairs, soon glabrous.
Leaves alternate, 1}-2 in. apart, including the 14 in. long
petiole 7-8 in. in length; leaflets 5-9, very occasionally 11,
opposite except the distal leaflet, the pairs 1-1} in. apart,
wide cuneate or rounded, obtuse or subretuse, mucronulate,
nerves 8-10-paired, dark green at length glabrous above,
paler more persistently adpressed pilose beneath, 14-23 in.
long, 1-14 in. wide, the petiolules } in. long; petiole and
rachis soon glabrous; stipules lanceolate or subulate, 4 in.
long, caducous; stipels 7! in. long, subulate. Flowers in
axillary 20-40-flowered racemes 3-8 in. long ; peduncles

crimson, sparingly hairy, boat-shaped and enclosing the
buds, } in, long, 4 in. across, ending in a recurved cuspidate

CULTIVATION.—So far as Kew is concerned this species 18

not new, for the plant from which the plate was prepared
was one of the many species bequeathed to this establish-
ment by the late Mr. G. C. Joad in 1881. It is, however,
scarcely known in gardens generally. Like its better
known congener, J. Gerardiana, its shoots at Kew die back to
the ground when the plant is grown in the open. Every
year, however, a crowd of slender, erect or suberect stems
about 4 ft. in length is sent up from the rootstock, and
these flower freely during August and September. The
shoots are not naturally of annual duration, and if the plants
were grown against a wall they would probably survive
our winters. The number of hardy shrubs which flower
at the same season as this is so limited that every addition
to them is weloome.—W. J. Bran.

Eucryphia cordifolia is a native of Chile, south of Lat.
38° S. and particularly common in the humid forests of
Chiloé and the provinces of Valdivia and Llanquihue. It
is a most ornamental tree, known to the Chilians as Muermo
or Ulmo. It was described and figured in 1797 by
Cavanille, who established on it the genus Hueryphia,
the systematic position of which has always been doubtful.
First Sprengel suggested an affinity with Rosaceae, then
Choisy attached it as an anomalous genus to Hypericaceae.
Endlicher removed it to Chlaenaceae, whilst Spach was the
first to point out a relationship with Ternstroemiaceae,
particularly with Zaplacea. Then in 1846 C. Gay made
Eucryphia the representative of a new order Eucryphiaceae,
which he placed near Chlaenaceae. Planchon, on the other

Avavst, 1908.

hand, was inclined to refer it to Saxifragaceae, among
which Belangera seemed to him toapproach Lucryphia. This
view was adopted by Bentham in the Flora Australiensis ;
but in Bentham and Hooker’s Genera Plantarum Hueryphia
was transferred to the Rosaceae-Guillajeae, to which group
Baillon also assigns it as an anomalous type. Quite
recently Hallier came to the same conclusion from an
examination of the morphology and anatomy of the genus.
Meanwhile Maximowicz had pointed to the Tiliaceae, and
more especially the Sloaneae and Elaeocarpeae, as possible
allies. Focke, however, the monographer of the Rosaceae
in Engler and Prantl’s Natiirliche Pflanzenfamilien, restored
C. Gay’s Eucryphiaceae as a distinct family allied to
Ternstroemiaceae and the other members of Engler’s sub-
series Theineae, and it is accordingly placed between
Dilleniaceae and Ochnaceae in Engler’s system. Under
these circumstances, and pending a more comprehensive
examination of the genus, it seems expedient to follow Gay
and Focke and treat Hucryphia as a distinct phylum with
the status of a family.

Loudon gives 1878 as the year of introduction of
Eueryphia cordifolia into English horticulture, but G. Don
has a paragraph containing directions for its cultivation
and propagation as early as 1831. However that may be,
it remained practically unnoticed until 1897, when it
flowered in Messrs. Veitch’s nurseries at Coombe Wood,
and a figure of it, together with a note by G. Nicholson,
was published in the Gardeners’ Chronicle. The leaves
are shown here as obtuse and elliptic to elliptic-oblong.
Subsequently another figure of Hucryphia was produced in
the same Journal, representing the leaves as very acute.
The specimen from which it was drawn came from the garden
of Mr. Gumbleton, who had obtained his plant from the
Coombe Wood nurseries, whence the branch figured on plate
8209 was derived. From the dried material at Kew it seems
that whenever acute leaves appear it is generally the first
leaves of a shoot which assume the acute shape, and in this
they resemble the leaves of the seedling plant.

According to Gay the wood of Eueryphia is much used
for joinery and light carpenter’s work and also for fuel.

Description.— Tree, attaining in its native country over

40 ft. m height, with a straight trunk, 1-2 ft. in
diameter. Branches tomentose when young, at length
glabrescent ; old branches with a brownish bark. Leaves
broad-oblong, obtuse or sometimes acute, with crenulate
or serrate-dentate margins, 2~3 in. long, 1-1? in. broad,
coriaceous, when mature quite glabrous, dark green and
shining above, softly pubescent and greyish below, network
of veins very close and distinct above; petiole tomentose,
1-1 jn. long. Flowers solitary, axillary, from perulate
tomentose buds; pedicels tomentose, J-1 in. long. Sepals
4, oblong, velvety, thrown off together. Petals 4, obovate-
rotundate, up to 1 in. long, thin, milk-white. Stamens
very numerous. Ovary glabrous; carpels and styles 10-12.
Capsule 3-2 in. long.—Orro Srapr.

Currivation.—This shrub is essentially one for the
milder parts of the British Isles. It has never succeeded
at Kew even when planted against a sheltered wall. But
for the gardens of the south and west of Ireland, the west
of Scotland, Cornwall and similar localities, where the
winters are mild and the summers equable and moist, it
ought to prove a most charming acquisition. Like £.
pinnatifolia (B. M. t. 7067), another but hardier species
from Chile, it should be given a peaty soil such as Rhodo-
dendreae love. In fact, wherever such species of
Rhododendron as R, grande and R. Griffithianum thrive,
there, both as regards climate and soil, will this Hucryphia
be very well suited.—W. J. Bran,

Rhododendron kamtschaticum is found abundantly in the
islands and along the coasts in the neighbourhood of
Behring Strait. It extends southwards to Sachalin and the
north of Japan, and eastward to Banks’s Island off the coast
of British Columbia. According to Pallas it occurs in
muddy mountainous places, and begins to flower about the
end of June. |

This pretty species, which in general appearance reminds
one of some of the Rock Roses, has been in cultivation for
at least a hundred years, but, owing probably to the
difficulty of its cultivation, it is still comparatively rare.

Descriprtion.—Undershrub about 6 in. high; branches
thick; branchlets clothed with long hairs. Leaves annual,
sessile, obovate or spathulate-obovate, rounded at the apex,
narrowed to the base, 14-24 in. long, 4-1 in, broad, papery,

Aveust, 1908.

long ciliate; lateral nerves 2-3 on each side of the midrib,
arched, pilose below; veins conspicuous on both sides.
Flowers solitary, terminating short branchlets; pedicels $-
3 in. long, glandular-pilose. Calyx 5-partite; segments
herbaceous, oblong, obtuse, 1-3 in. long, 3-nerved, nerves
and margins pilose. Corolla carmine purple ; lobes spread-
ing, oblong-elliptic, obtuse, about 2 in. long and 3 in. broad,
thinly villous outside. Stamens 10; filaments unequal,
villous at the base, about 4 in. long; anthers +, in. long,
glabrous. Ovary ovoid, sparingly pilose; style villous at
the base ; stigma capitate, shortly 5-lobed. Capsule oblong,
about 4 in. long.—J. Hurcurnson.

- Currivation,—This interesting and remarkable Rhodo-
dendron is not one of the easiest to cultivate in this country,
and it cannot be accommodated so readily as most of the
species. It is quite capable of withstanding any degree of
winter cold it is likely to experience in the British Isles ;
but it is deciduous and, like many other deciduous plants
from North Asia, is excited into growth early. In conse-
quence it is liable to have its young growths injured by
late spring frosts. Then it is, even more than most species
of Lhododendron, a moisture-loving plant. At Kew it has
succeeded best when grown in a mixture of peat and silver
sand to which a certain spongy consistency has been given
by adding a little chopped sphagnum. It should be given
a position where it is shielded from early morning sun in
spring, though otherwise fully exposed, and where the soil
is, naturally or artificially, kept always moist. The plant
from which our figure was prepared is one of a batch raised

from seeds obtained from the Botanic Garden at St. Peters-
burg in 1900.—W. J. Bran. 3

Polystachya is a large and polymorphic genus, widely
diffused through the warmer regions of the globe, though at
present it is not known to occur further east than Borneo
and the Philippine Islands. Its headquarters are in Tropi-
cal Africa, from which country 74 species were known
when the Flora of Tropical Africa was published, and the
number has since been increased to over one hundred.
Very few of the species can be considered showy, and only
three have hitherto been figured in this work, namely,
P. grandiflora, Lindl., t. 3707, P. bracteosa, Lindl. (now con-
sidered to be synonymous with P. affinis, Lindl.), t. 4161,
and P. pubescens, t. 5586, the two former being from
Tropical Africa, ‘the latter from extra-tropical South Africa.
The one now figured is very distinct from these, and indeed
from all others in cultivation, in its rose-pink lip, which
renders the plant very attractive. It was discovered in the
Upper Zambesi district by Mr. John Buchanan, who sent

Auaust, 1908.

plants to Mr. James O’Brien, though from some misappre-
hension the habitat was recorded as Sierra Leone when the
species was originally described from the collection of Sir
Trevor Lawrence, Bart., Burford, Dorking, where it flowered
in July, 1893. The former locality has since been confirmed,
for the species has also been collected on the Zomba Hills,
Nyasaland, at 6,000 feet elevation, by Lieut.-Col. W. H.
Manning, in November, 1900. It is one of a group of
Tropical African species, which are for the most part known
only from dried specimens.

Descriprion.—Epiphyte, about 6 in. high. Pseudobulbs
ovoid-oblong, somewhat compressed, 1-14 in. long, covered
with membranous imbricating sheaths, 2—3-leaved. Leaves
linear-oblong, subobtuse, recurved, 24-44 in. long, 3-} in.
broad, subcoriaceous. Inflorescence terminal, 3-6 in. long,
pubescent ; raceme 4—8-flowered. Bracts broadly rhomboid-
ovate, abruptly acuminate, puberulous, 4-3 in. long.
Pedicels puberulous, under 3 in. long. Flowers medium-
sized, inverted, yellowish green with a rose-pink lip.
Sepals somewhat spreading, puberulous; dorsal ovate,
acute, concave, about 4 in. long; lateral ovate, acuminate,
concave, rather longer than the dorsal. Petals subconni-
vent, incurved, oblanceolate-oblong, subobtuse, about 4 in.
long. Lip superior, 3-lobed, nearly 4 in. long; side lobes
rounded or obscurely angled, subobtuse, short; front lobe
obovate-orbicular, apiculate, fleshy, channelled, nearly 4 in.
broad; dise with an obscure rounded callus about the
centre, puberulous behind. Column very short and broad,
without wings.—R. A. Ronrr.

Cuttivation.—Kew is indebted to the Royal Botanic
Gardens, Glasnevin, for a plant of this pretty species of
Polystachya, which was received in 1903 and flowered in
_ June, 1906. There are not many of the numerous species
of Polystachya that are sufficiently attractive to hold a
place among garden orchids. Twenty-four of them are in
cultivation at Kew, and of these the largest flowered is
P. grandiflora, whilst the brightest coloured is the yellow-
flowered P. pubescens. ‘The species here figured is at least
as attractive as either of these. Polystachyas generally
are easily kept in health if grown in a warm, moist house,

and afforded the same treatment as answers for Dendrobium
nobile, namely, a small teak basket filled with a mixture of
peat fibre and sphagnum for the roots, which should be
kept wet during the growing season and dry whilst the
plant is at rest. The flowers are developed in summer.—

The Rhododendron here figured was first collected by
Sir George Watt in the mountains of north-east Manipur,
on the eastern frontier of India, and it is undoubtedly one
of the finest forms of the genus. It differs from typical
R. Maddeni (B. M. t. 4805) in having much longer calyx
segments and obtuse leaves, which are somewhat rounded
at both ends. It is treated, therefore, as an eastern form
of this species, which has so far only been recorded from
Sikkim and Bhotan. It also resembles R. Datlhousiae,
Hook. f., the calyx segments of which, however, are much
broader and are usually ciliated,

J. Hurcnison.

Cutivation.—Rhododendron Maddeni, var. obtusifolia,
was raised from seeds forwarded to Kew in 1882 by Sir
George Watt, who collected them in Manipur during the
Demareation Commission of 1881-2. The plant figured
has been grown under glass, and is now planted in a border
in the Himalayan House, where it has formed a well-
furnished bush about 10 ft. high. It differs in habit and
several other characters from the Himalayan 2. Maddeni as
represented in gardens. It has not been tried out of doors
at Kew, where R. Maddeni is not hardy, but judging by
its behaviour in the Himalayan House the treatment that

answers for the majority of the Himalayan species of the

genus, including Ft. Maddeni, will suit the plant now
figured. W. Warson.

Robinia Kelseyi, like most other species of the genus,
is highly ornamental; it is very similar in habit to R.
viscosa, Vent., var. macrophylla, the flowers being of the
same colour, but smaller. The only reference we have
found to this hitherto imperfectly described species is in
the publication cited above, where it is stated that R.
Kelseyi is a new species discovered and introduced in 1901
by Mr. Harlan P. Kelsey ; that the bark much resembles
that of R. Pseudacacia; that the plant is sparingly pubes-
cent ; and that it is a compact shrub of distinctive habit.

Description.— Shrub, 3-10 ft. high, spreading. Branches
glabrous. Leaves pinnate; common petiole usually 4—6 in.
long, nearly glabrous, with a small groove on the upper
side; stipules subulate, pilose ; leaflets in 4-5 pairs, oblong-

glandular hairs; style recurved, stigma subcapitate. Pod
oblong, acute, 13-2 in. long, densely clothed with glandular
hairs. Seeds 3-4, funicle very short.—J. Hurcainson.

Cuntivation.—Robinia Kelseyi was purchased for the
Kew collection from Mr, H. P. Kelsey of Boston, Mass.,
U.S.A., in the spring of 1903. Although its affinity with
f. hispida is apparent, it is quite distinct in habit and
‘appearance. At present it seems likely to form a small
tree, and has not the rank growth of BR. hispida, which
renders that species so liable to injury by wind. It flowers
regularly in early or mid-June, and is then a most attractive
object, the shoots of the previous year being covered with
numerous short racemes of rose-coloured flowers. Its fruits
also are ornamental. In June last a specimen in the

Agave (§ Littaea) Watsoni, J. R. Drummond et C. H. Wright, in Kew Bull.
1907, p. 322; species A. expatriatae, J. N. Rose, maxime affinis, a qua
inflorescentia breviore sed latiore, foliorum pagina superiore vix concava et
spinis marginalibus minoribus parum uncinatis differt.

Caulis perbrevis. Folia 15-20 densius rosulata, laete viridia; exteriora sub
anthesin patentia, anguste oblongo-lanceolata, circa 50 em. longa, basi
tumescente 8 mm. crassa ibique 9°5 em. lata, cervice facie superiore
convexa 5°5 cm. lata, inde facie superiore fere plana, versus apicem grada-
tim expansa medioque 7°5 cm. lata; interiora erecta, angustiora, in
bracteas sensim abeuntia; omnia vitta marginali castanea tandem cineras-
cente ornata, marginibus aculeis circiter 5 mm. longis basi compressis vix
uncinatis inter se 2 cm. remotis apiceque spina obtusiuscula 1°8 em.
longa armata. Scapus fere 2°5 m. altus, ad basin 3°5 em., sub spicam
floriferam 2 cm. crassus, cylindricus, bracteis imis exceptis patentibus
subtiliter sulcatis albidis instructus. Flores viridescentes, staminibus pur-
purascentibus, in spicam densiorem fere 10 cm. latam aggregati. Bracteae
inter alabastra inconspicuae, vix 1 cm. longae, supra basin abrupte con-
strictae, conduplicatae, in setas firmas subulatas scariosas abeuntes.
Ovarium inferum 18-14 mm. longum, 5 mm. latum, subtriquetrum.
Perianthii tubus supra ovarium abrupte constrictus, manifeste 6-sulcatus ;
lobi ovario aequilongi, subcarnosi, viridescentes, marginibus albido-pellu-
cidi. Stylus robustior, 3°5 em. longus, albido-pellucidus, purpurascens ;
stigma papillosum.

The Agave here figured flowered at Kew in the spring
of 1907. As regards inflorescence it is nearest to A. densi-
flora, Hook. (B. M. t. 5006), which has also somewhat the
same type of leaf, but with different, far more closely set
margin-prickles; the apple-green leaf, with an almost
convex neck, and flat upper surface of the blade, resembling
that of A. (Huagave) decipiens, Baker, should serve to
distinguish A. Watsoni from all known Littaeae, not
excluding A. expatriata, Rose, which is only known to us
from the author’s photograph and description.

Desoriprion.—Stem very short. Leaves apple-green,
15-20 in a moderately dense rosette, the outer, at the time
SEPTEMBER, 1908.

of flowering, spreading, narrowly oblong-lanceolate, about
20 in. long, dilated base over } in. thick, and 33 in. broad,
neck about 21 in. broad, convex on its upper surface,
greatest width of leaf, at about 9 in. from the base, about
3 in., upper surface almost flat upwards, except just below
the tip, which bears a rather blunt, finely grooved spine,
less than # in. long; margins with an extremely narrow
ribbon, brown when young, ashen grey with age, armed at
intervals of about # in. with prickles under 3 in. long,
compressed at their bases, narrowly triangular in outline,
tips not obviously hooked. lowering stem not quite 9 ft.
high, diameter 14 in. at the base, less than an inch just
below the spike of greenish flowers, with purplish filaments
and anthers, which before withering give the spike a
diameter of a little less than four inches, PBracts suddenly
narrowed above their bases and folded into a firm, awl-
shaped scarious bristle, whitish and conspicuous on the
scape, but hidden by the buds and blossoms. Ovary rather
more than $ in. long by } in. broad ; tube sharply constricted,
plainly six-furrowed. Perianth-lobes about the same Jength
as the germen, rather fleshy, green with white translucent
edges; style robusi, suffused with purple ; stigma papillose.
—J. R. DrumMonp.

Curivation.— Agave Watsoni was purchased in 1906
from Mr. Justus Corderoy, Blewbury, Didcot, who obtained
it originally from the Ghiesbreght Collection as an unnamed
species. It flowered at Kew in 1907 under the usual
conditions of cultivation. Unless there are other plants of
it elsewhere it is likely to be lost to cultivation, as it has
produced neither seeds nor offsets. —W. Watson.

Mr. Hiern’s monograph of Zaluzianskya in the Flora
Capensis includes 32 species, all of which are confined to
South Africa. The difficulty of distinguishing some of
them is considerable, and it is questionable whether all are
really distinct. Bentham suggested that the plant here
figured might be only a variety of 7. lychnidea, which, as
Erinus lychnidea, is depicted at t. 2504 of this work, and
Mr. Hiern suspects the identity of 7. lychnidea and Z.
capensis, Walp. Both are recorded as being in cultivation,

SEPTEMBER, 1908.

the former as long ago as 1823, while 7. selaginoides, Walp.
(= Z. villosa, F. W. Schmidt) also finds a place in some of
our horticultural dictionaries. It is probable that they soon
disappeared, for like many Scrophulariaceae with strikingly
attractive flowers the species of Zaluzianskya do not appear
to thrive for long when removed from their native environ-
ment. The flowers of 7. maritima, as in other species of
the genus, open only in the evening or in dull weather.
When expanded they are very fragrant.

Z. maritima is widely spread in South Africa, and is met
with at a low level near the sea as well as far inland at
elevations up to 4,000 ft. or more. Mr. Hiern records
five varieties, one of which (var. grandijlora, Hiern) has
the limb of the corolla as much as an inch across.

Description.—Herb, perennial. Stem erect, decumbent
or ascending, often slightly shrubby at the base, simple or

sparingly branched, rather densely leafy, pubescent or
puberulous, 3-3 ft. high. Leaves thinly coriaceous,

obtuse, glabrous or puberulous, usually 3-nerved, quite
entire or remotely toothed; lower subsessile or shortly
stalked, very much narrowed towards the base, narrowly
elliptic, obovate-oblong or lanceolate-oblong, 1-3 in. long,
4-% in. broad; upper sessile, gradually becoming smaller,
often adpressed; floral-leaves sessile, amplexicaul, broadly
lanceolate, 3-1 in. long. Spikes elongated, rather densely —
flowered. Caly« tubular, }-2 in. long, deeply 2-lipped,
pubescent or slightly ciliate; teeth small, ovate-deltoid or
ovate-lanceolate, obtuse. Corolla marcescent, glandular-
puberulous and deep red or purple-brown outside, shining

white inside, or the lobes of the limb sometimes bordered _ a

with rose ; tube very slender, 13-2 in. long; limb spread-
ing, 5-cleft, }~? in. across; lobes obovate, bifid. Stamens 4,
glabrous, the 2 longer slightly exserted. Style filiform,
exserted. Capsule coriaceous, oblong, about 4 in. long.—

S. A. SKAN.

Cunrivation.—This Zaluzianskya was presented to Kew

by Mr. W. E. Gumbleton, who raised plants of it fro

seeds obtained by him from Mr. Thorncroft of Barberton.
It has behaved here as an annual, for plants tried in the _
herbaceous department, as well as others grown in the Cape

House, died after flowering; they also failed to produce
seeds. The treatment most suitable for such half-hardy
annuals from South Africa as Rhodunthe, Diascia, and

Nemesia would probably also suit this Zaluzianskya.—
W. Watson.

Bulbophyllum galbinum is a native of the Malay Peninsula,
and was described about twelve years ago by Mr. Ridley,
Director of the Singapore Botanic Garden, from materials
collected on Maxwell's Hill, Perak, where it is said to be
abundant, climbing on trees in dense jungle. It was com-
pared with B. Reimwardtii, Reichb. f., to which it bears a
general resemblance in habit, ast it is readily dis-
tinguished by its two-flowered peduncle. It had previously
flowered at the Royal Botanic Garden, Glasnevin, and was
at first referred to B. Reinwardtii. Mr. J.J. Smith refers
(Orch, Java, p. 448) both B. feinwardtii, Reichb. f., and
B. galbinum, Ridl., to B. uniflorum, Hassk., though the one
now figured does not at all answer to the name, and several
species of the section Sestochilos are persistently 1-flowered.
Whether B. Reinwardtii be in cultivation is doubtfui,
though Reinwardt’s original drawing and a dried specimen
collected by Thomas Lobb, in Java, which Lindley con-

SerrTemseEr, 1908,

sidered identical, are preserved in the Herbarium of the
latter, now at Kew. Micholitz also collected plants appa-
rently of the same species in Sumatra, and carefully noted
the peduncles as being 1-flowered, and all the four present
are in this condition. Having regard to these facts it is
difficult to regard all these forms as one spécies, and the
species of this affinity certainly require careful revision from
living specimens, or at all events from more complete
material than is yet available.

Descriprion.—Herb

epi hytic, with stout, long-creeping
rhizome. Pseudobulbs 34-44 in. apart, narrowly oblong, some-
what compressed, 2-34 in. long, covered with membranous

This is perhaps the handsomest of the Globe Thistles in
cultivation. It was originally described from cultivated
plants raised in the Dorpat Botanic Gardens from seed
collected on Mount Ararat, and Kew possesses what may be
considered a type specimen, communicated by Ledebour to
the late Sir William Hooker. The one flower-head is larger
than any other we have seen of this species, being, as
flattened out, 6 in. across. Incidentally it may be mentioned
here that the apparent flower-heads are agglomerations of
one-flowered capitula, each invested by an_ elaborate
involucre of bristles and bracts.

OotoBER, 1908.

Echinops is a genus of upwards of seventy species,
ranging from Europe and North Africa, across Asia to
China and Japan, and a few species are peculiar to the
mountains of Tropical Africa. The European, Asiatic and
North African species present no striking contrasts, and
have either white or blue flowers; but some of the Tropical
African species are very different from each other and from —
the rest of the genus. Thus £. amplexicaulis, Oliv., has
pink or crimson flowers; E. giganteus, A. Rich., grows as
much as 16 ft. high, and L. chamaecephalus, Hochst., is
almost stemless with huge solitary heads of flowers.

The process of the dispersal of the pollen of Lchinops
is the same as in Centaurea. It is discharged into the
cylinder formed by the connate anthers before the expansion
of the corolla and the elongating style pushes some of it out
at the top, whilst the rest is ejected by a sudden contraction
of the filaments, which pulls the anthers down. But the female
stage, the divergence of the style-arms, sometimes follows so
quickly in E. Tournefortii, that self-fertilisation seems possible.

Descriprion.—Perennial, from 3-5 ft. high. Leaves
large, pinnately divided, lower ones tripinnate, 1 to 14 ft.
long, gradually smaller and less divided upwards, ultimate
lobes ending in strong spines, slightly rough on the upper
surface, clothed with a white felt beneath. /lower-heads
few, globose, 24-3 in. or sometimes as much as 5 in. in
diameter, terminal on long stalks, each flower surrounded
rs an involucre of bristles and sharp-pointed bracts.

orolla white, tubular, slightly overtopping the bracts;
limb 5-parted; lobes linear, reflexed. Anthers exserted,
blue. Achenes densely clothed with long, straight, coarse
hairs. Pappus of five small scales, concealed by the hairs.
—W. Borrine Hemsiey.

Cuntivation.—Echinops Tournefortii grows freely and
flowers in August along with the other Globe Thistles and
appears to be quite as hardy as any of them. It came
originally from Canon Ellacombe’s garden at Bitton, where
the plant figured was grown in 1906.—W. Warson.

Rosa sericea, var, pteracantha, occurs in company with the
typical form which is abundant at elevations of from 3,000-
11,000 ft. Of the Indian specimens which represent the
true species at Kew, only those collected in Manipur by Sir
George Watt have prickles as large as in this Chinese
variety, though it is understood that occasionally shoots
with bead prickles are to be met with in the Eastern
Himalaya.

The plant here figured differs from that described by
Franchet in having glabrous leaves, but the specimens at
Kew show intermediate forms which link the two. The
stems are sometimes devoid of the setulose bristles which
accompany the remarkably large, red, translucent prickles ;
and the latter are often absent from the branches which bear
the flowers.

Descriprion.—Shrub, robust, much branched, forming a
bush as much as 10 ft. in diameter. Branches often densely
setulose ; prickles large, red, compressed, decurrent, elongated

diameter, bright red.—J. Hurcainson.

Cutivarion.—Hitherto Roses have been grown in
gardens chiefly for the beauty and fragrance of their
flowers and for their fruits, but in this new Chinese variety
the large, beautifully coloured prickles provide a new and
additional source of attraction. They constitute the most
striking feature of the variety, for the flowers are not so
large as in the typical R. sericea. The plant from which
our figure was made was purchased from Messrs. Paul of
Cheshunt in 1906, but European gardens owe its first
introduction to Mr. Maurice L. de Vilmorin, in whose
Fruticetum at Les Barres it has for some years been the
most remarkable of a numerous series of Chinese forms of
ft. sericea, Like Roses in general this needs a good strong
soil to bring out its full attractions; it should preferably be
grown in a rich, rather stiff loam. The beauty of its
prickles is most marked on strong vigorous shoots of the

current year; the second year they become grey and
woody.—W. J. Bran. 4 ad

Anisotes is a small genus allied to Justicia, and includes
one Arabian and four Tropical African species in addition
to the endemic Socotran A. diversifolius.

According to Balfour (lc. p. xlili.), the family of
Acanthaceae attains a remarkable development in Socotra,
where it furms about one-twentieth part of the flora, com-
prising 27 species which are included in 15 genera. Three
of the genera and 21 species are endemic, so that over
one-seventh of the endemic genera of Socotra and one-tenth
of the endemic species belong to the Acanthaceae.

The venation of the corolla in Anisotes diversifolius is
peculiar : three veins start from the base of the corolla-tube,
one corresponding to the lower lip and two to the upper,
and the two latter each divide into three a short distance
above the base as shown in fig. 3.

SPRAGUE.

CuLrivatTion.-—Kew is indebted to Colonel Beddome for
a plant of this little shrub which grew about 18 in. high
and flowered in April in a warm greenhouse, where it
continued to develop flowers till July. It is similar in its
habit and requirements to some species of Justicia, Jacobinia
and Peristrophe, and as it agrees with these in being easy to
propagate by means of cuttings it may well be grown along
with them for conservatory decoration in spring. It also
matures seeds under cultivation.— W. Warson. |

vol. i. (1898), p. 82.

The delimitation of the genera Lewisia and Calandrinia
is a subject as to which authors are by no means in agree-
ment. Robinson in the place cited above extends Lewisia,
and includes under it the Oreobroma of Howell, and he is
followed here, as he was by Sir Joseph Hooker under
t. 7633. But we are not convinced that this is a good
solution of the difficulty. Lewisia rediviva, Pursh (B. M.
t. 5395), the species on which the genus was founded,
differs from the present plant in having usually seven
sepals, numerous petals, indefinite stamens and about eight
style-branches, and has perhaps valid claims to independent
generic rank. :

Lewisia Cotyledon is a very attractive plant; its flowers
remind one strongly of those of some species of Ozalis.

Desoription.— Perennial, stemless, with a thickened
root-stock. Leaves fleshy, rosulate, oblong-spathulate,
13-23 in. long, glandular on the margin when young.

Flower-scapes 4 to 5 in. high, 8~12-flowered, bracteate
throughout. #racts about a third of an inch long, glan-
dular on the margin. Pedicels curved downwards before
the flowers expand. lowers about 11 in. in diameter,
white with crowded red lines. Sepals 2, broad, fringed
with stalked glands, overlapping in bud. Petals variable
in number, usually 9 or 10, spathulate, notched. Stamens
7 to 10, shorter than the petals. Ovary I-celled; ovules
few; style equalling the stamens.—W. Borrine Hemstry.

Cuitivation.—Lewisia Cotyledon was presented to Kew
in 1906 by Mr. P. B. Randulph, Seattle, Washington; the
plant came from the Siskiyou Mountains, Oregon. It grew
well and flowered freely in May after being potted in sandy
soil and placed in an unheated frame. Possibly it will
prove hardy in a sheltered position in the rockery. So far
it has failed to produce seeds, but it has developed basal
offsets which when removed soon grew into plants.—

This interesting little plant is likely to prove of consider-
able economic importance, since its tubers yield a large
quantity of Rubber said to be of good quality. It has bgen
identified by Dr. Stapf with the “ Ecanda” or “ Marianga ”
Rubber-plant, first recorded by Professor Geraldes in his
‘“Kstudo sobre os latex borrachiferos,” pp. 143-172, pub-
lished at Lisbon in 1906, and a full account of it is given
in the Kew Bulletin above quoted, from which, according
to Professor Geraldes, the plant is a native of the interior of
Angola, growing in the drier parts of treeless, sandy and
alluvial areas between the River Kwanza and the River
Zambesi, at an altitude of from 4000 to 5500 ft. above
sea-level.

It is seldom that a species of Raphionacme is seen in
cultivation in Europe, this being the first to be figured in
the Botanical Magazine, although no fewer than 25 species
have been described, nine of them natives of South Africa,
the remainder Tropical African. &. divaricata, Harv., one

This showy shrub was first described as long ago as 1827,
from specimens collected by Thonning on the Gold Coast,
but the oldest herbarium specimens at Kew were collected
by Mr. Gustav Mann in February, 1862, in the Cameroons,
at an elevation between 3,000 and 4,500 ft. It has since
been collected by numerous travellers in various localities,
from Sierra Leone to Angola and eastward ‘to Uganda,

November, 1908.

forming one of the most striking objects on the outskirts of
forests. Most of the wild specimens are of more compact
habit than the plant figured, and have smaller leaves
on quite short stalks, and the larger calyx-leaves are
even more brilliantly coloured, due doubtless to greater
light.

* Missuada comprises about fifty species which inhabit
tropical Asia, Africa and Polynesia, but few of them are in
cultivation. The best known is M. frondosa, L., figured in
the Magazine (t. 2099), from a weakly plant, under the
name of M. pubescens. The only other one figured in this
publication is J. luteola, Del. (t. 5573), a very pretty
species from the upper Nile region.

Not all of the species of Mussaenda have a leaf-like,
coloured calyx-lobe, and usually only one flower in each
partial cyme of an inflorescence possesses this appendage 5
but this characteristic is shared by several other genera
belonging to different tribes of the Rubiaceae. They
are : Calycophyllum, Monadelphantha, Capirona, Schizocalyz,
Pinkneya, Pogonopus (Howardia caracasana, Wedd., B. M.
t. 5110), Pallasia and Warscewiczia; all American.

Description.—Shrub, either suberect or climbing on trees
to a height of forty feet or more. Branches, leaves and
flowers more or less clothed with soft hairs. Leaves thin,
very variable in outline, from lanceolate to nearly orbicular
and with the stalk sometimes as much as 6 or 7 in. long,
but usually smaller, rounded, cordate or wedge-shaped at
the base, gradually tapering or abruptly acuminate at the
tip, margin entire, minutely fringed, both surfaces slightly

airy; primary veins conspicuous, often coloured red ;
stipules bifid or trifid, about 1 in. long. Flowers about
1f in. across, in dense terminal cymes, some sessile, others
shortly stalked, clothed with long spreading crimson hairs
on the outside, yellow within changing to red, crimson in
the centre, Calyz-lobes 5, all lanceolate, 1-4 in. long,
acute, or one leaf-like oval (variable in wild specimens),
sometimes as much as 5 in. long by 4 in. broad, brilliant
crimson, longitudinally 5- or 7-nerved, slightly hairy.
Corolla salver-shaped, bearded in the throat. Stamens 5,

included. Ovary 2-celled ; cells many-seeded; style in-
cluded.— W. Borrrye Hemstey.

CuLrivation.—Kew is indebted to Mr. H. N. Ridley,
Director of the Singapore Botanic Gardens, for this hand-
some plant, which he forwarded in a Wardian case in 1907.
It was first introduced into cultivation by Mr. Gustav Mann
in 1863; at any rate, there is a note written by him on a
sheet in the Kew Herbarium to the effect that living
plants brought by him from West Africa were in the >
Garden at that time. But it does not appear to have
become established then. Nor was it successfully grown in
England when the late Mr. W. Bull distributed it twenty
years later. It was included in his Catalogue of New Plants
in 1888, p. 8, where it was described as “a remarkable
introduction from the Congo.” Mr. W. Micholitz, collector
for Messrs. Sander & Sons, of St. Albans and Bruges,
writes :—“ I found Mussaenda erythrophylla on the banks of
the Kwilu, Loango, French Congo, in 1886, it being then
new. The plants that I brought to England in May or
June of that year were handed over to Mr. W. Bull, the
Chelsea nurseryman, who distributed them as M. erythro-
phylla, but I am not aware that any of them flowered. Ii
is usually of a somewhat creeping or trailing habit, and
only attains the shrubby character of J. frondosa when
growing in the open with full exposure to the sun. As I
found it, growing in partial shade in tall virgin forest on
the water’s edge, it reached the tops of the trees, and,
forming as it did long stretches of a high, solid wall of
dazzling scarlet, was a sight not easily to be forgotten.”
At Kew the plants received from Singapore have been
grown in a moist tropical stove, where they have formed
shapely, well-furnished shrubs about 2 ft. high, and
were in flower for about two months. This Mussaenda is
likely to become a popular garden plant, the red calyx-
leaves being quite as effective as the bracts of Poinsettia,
and they appear to be quite as persistent.—W. Watson.

Meconopsis sinuata, not known in gardens, and rare in
Alpine Sikkim and Bhutan at 10-12,000 ft., is closely allied
to M. aculeata, Royle (B. M. t. 5456), the North-west
Himalayan prickly “Blue Poppy,” but has narrower, slightly-
lobed leaves and longer capsules, widest above the middle.
The plant here figured, whose introduction we owe to
Lt.-Col. H. Appleton, is rare in Northern Kashmir at
10—14,000 ft., where it had previously only been met with
by Falconer in 1838, by Winterbottom in 1847, and by
Clarke in 1876. Its leaves are as wide as in M. aculeata,
but as slightly lobed as in M. sinuata; its flowers differ
from those of M. aculeata in having a narrower, more
prickly ovary, and a deep pink or bright orange instead of

NovemBeEr, 1908.

a pale green stigma; its capsules are, though shorter,
obconic as in M. sinuata, not widest below the middle as in
M. aculeata. It may prove distinct, but, till it can be com-
pared with living plants of M. sinuata, is best treated as a
variety, latifolia, of that species, with wider leaves and
shorter fruits. Clarke met with M. aculeata as well as this

plant in Kashmir, and in the field has noted that they
differ.

Description.—Herb, apparently monocarpic; root stout,
fusiform; stem simple, scapose, 1-4 ft. high; sparsely
covered, like all parts of the plant except the petals, stamens
and style, with spreading prickles. Leaves many ; radical
soon disappearing; cauline alternate, linear-oblong or
lanceolate, or (var. latifolia) oblong, with obtuse tips,
irregularly shallowly lobed or sinuate margins, and bases
gradually tapering into the petioles, green above, somewhat
glaucous beneath, 4-7 in. long, 3-14 in., or (var. latifolia)
14-2 in. wide; lower petioles 14-24 in. iong, gradually
shorter upwards and suppressed as the leaves pass into
bracts. Flowers in raceme-like cymes; pedicels 3-23 in.
long, bracteate except the uppermost ; bracts leaf-like, sessile.
Sepals 2, ovate, 4 in. long. Petals 4, blue, wide-ovate,
often slightly cuspidate, 1d in. long, 14 in. wide. Stamens
numerous, several-seriate ; filaments slender, distinct, deep
blue; anthers yellow or pale orange. Ovary 4—carpelled,
rather closely prickly, ovoid ; style glabrous; stigma usually
deep-pink, less often bright orange. Capsule obconic,
ppecugly prickly, 14-12 in., or (var. latifolia) 1-14 10.
ong. :

CuLrivation.—Seeds of Meconopsis sinuata, var. latifolia,
were sent to Kew from Kashmir by Lt.-Col. Appleton in
February, 1906; the plants flowered in June, 1908. The
treatment suitable for M. aculeata, which succeeds best in
most shady places, planted in a peaty soil, should be
adopted for this plant also, which loses its crown of leaves
during winter.—D. Prat.

Hook. f., a@ qua ramulis glabris, petalis acutioribus, glandulis minoribus
differt.

Frutex 1-2 m. altus, ramis angulato-striatis cinereis. Folia obovato-cuneata,
apice rotundata, mucronata, 2-4 em. longa, 0°8-1°5 em. lata, integra vel
spinuloso-serrata, spinulis 1 mm. longis; venae laxae, utrinque conspicuae ;
spinae 3- vel 5-partitae, 1-2 cm. longae, patentes. Flores solitarii vel
fasciculati, circiter 2 cm. diametro, perulis ovatis; pedicelli graciles,
1°5-2 cm. longi. Sepa/a 6 vel 7, subaequalia, ovata vel elliptica, 6-8 mm.
longa, 4-5 mm. lata. Petala late obovata, subacuta, leviter emarginata,
5-6 mm. longa, 3-4 mm. lata, pallide flava, glandulis 2 ellipticis 0°75 mm.
longis intus basi instructa. Stamina quam petala duplo breviora. Stigma
Seman capitatum, acca rubra, ellipsoidea, LO-15 mm. longa, 7-8 mm.
diametro.

Though very closely allied to Berberis macrosepala,
Hook. f., B. yunnanensis is nevertheless distinguishable by
more characters than are indicated by Schneider in the
places cited above. He states that the only difference he
could find between the two species was that the young
branches of B. yunnanensis were glabrous and those of
B. macrosepala shortly pubescent. In B. yunnanensis, how-
ever, the petals are acute and scarcely emarginate, and bear
small rounded glands; whereas in B. macrosepala they are
obtuse with a broad, widely emarginate apex, and the glands
are larger and more elongated.

B. yunnanensis was first discovered by Delavay in 1885
near Lankong, Yunnan, at an altitude of 10,000 ft. Since
then it has been collected in Western China by Wilson, who
also gathered B. maerosepala in the same region; thus
greatly extending the known range of that species, which
was known only from the Sikkim Himalaya.

Novemser, 1908.

Descriprion.— Shrub, 3-6 ft. high; branches angular-
striate, greyish. Leaves obovate-cuneate, rounded at the
apex, mucronate, 3-14 in. long, 4-2 in. broad, entire or
spinose-serrate ; veins few, conspicuous on both surfaces ;
spines three- or five-partite, 2-3 in. long, spreading ; scales
of the winter-buds ovate. Flowers solitary or in few-
flowered fascicles, 3 in. in diameter ; pedicels slender, 3—$ in.
long. Sepals 6 or 7, subequal, ovate or elliptic, about 4 in.
long. Petals broadly ovate, subacute, very slightly emar-
ginate, } in. long, pale yellow; glands of the petals elliptic.
Stamens half the length of the petals. Stigma subsessile,
capitate. Berry red, ellipsoid, 1—} in. long, about 4 i.
wide.—J. Hurcsinson.

Cutrivation.—Berberis yunnanensis is one of the new
Barberries introduced to cultivation by Mr. Maurice L. de
Vilmorin, and it is to him that Kew is indebted for the
plant from which the plate was prepared. It was received
in February, 1907. It is a bush of dense rounded habit, at
present 2 to 3 ft. high. The flowers are large as compared
with those of other cultivated Barberries, as is also the
fruit. The species is a welcome addition to a beautiful
group of hardy shrubs. Barberries are not fastidious as to
soil; in the sandy soil of Kew they thrive better than most
shrubs, and they produce seeds sufficiently plentifully to
afford a simple means of increase.—W. J. BEAN.

Columnea magnifica was discovered about sixty years ago
by the orchid collector, Warscewicz, in the province of
Veraguas, Panama, and does not seem to have been collected
again until 1906, when it was discovered in the mountains
of Costa Rica by Carlos Wercklé, at an altitude of between
6,000 and 7,000 ft.

Although placed by Hanstein in the section Pentadenia, —
its real affinities seem to be with C. scandens, Linn., and
C. rotundifolia, Salisb., which are placed in the section
Eucolumnea.,

The headquarters of the genus are in Central America, |
where it attains its maximum development in Costa Rica.
Numerous species are endemic in the South American
Andes, and a few in the West Indies.

Description.—Herl, erect, about 1 ft. high, villous-
hirsute. Leaves oblong to oblanceolate, acute, 1-24 in.
long, 1-3 in. broad, obscurely serrulate, roughish with

about 14 in. long; limb very unequally two-lipped ; lobes 4,
upper orbicular-oblong much exceeding the others, lateral
adnate to upper for more than half their length; lower
linear-lanceolate, 3-1 in. long, finally deflexed. Anthers
connate. Disk represented by a single large posticous
emarginate gland. Ovary villous.—T, A. SPRAGUE.

Cuttivation.—This plant was introduced into cultiva-
tion by Messrs. V. Lemoine & Sons, Nancy, about 4 years
ago. It first flowered at Kew in 1906. The figure here
given has been prepared from specimens presented by
Col. Beddome and by Mr. W. E. Gumbleton. Like the
other species of Columnea in cultivation this grows and
flowers freely in a warm house under conditions such as suit
Gesneraceae generally. Compared with C. scandens (B. M.
t. 5118) and C. Schiedeana (B. M. +. 4045) it is not a robust

grower, but it is likely to prove useful for pot culture.—

This pear has been in cultivation in Northern China and
Japan for a considerable time, and according to Siebold
several varieties have been raised from it in Japan. It was
introduced into this country by Captain J. P. Wilson in
1820. A fruit produced from a graft in 1823 was described
by Lindley as measuring nearly 3 in. in length and 23 in.
in diameter, forming almost a perfect oval, covered with a
pale dull yellow skin with numerous rough brown spots,
and possessing a white crisp flesh with the flavour of an
apple rather than of a pear, and of no particular excellence.
A very savoury and aromatic variety was sent by Mr. Simon
to the Jardin des Plantes at Paris in 1861. It was described
as P. Simonii by Carriére. Dr. Bretschneider remarks that
Simon’s pear is very likely the pai-li (white pear) of the

November, 1908,

Chinese, which is much cultivated in the Province of Chili
for its delicious, pale yellow, apple-shaped fruit. Otherwise
P. sinensis is known in China as sha-li (sand pear) and
was mentioned as such by Roxburgh in his Hortus
Bengalensis in 1814. According to him it was introduced
into the neighbourhood of Calcutta before 1794, but it pro-
duced little truit and that of very bad quality. He figures
the pear in an unpublished drawing as much depressed at
the top. On the other hand, a very fine coloured Chinese
drawing in the Kew collection shows the pear almost
globose, of a dull yellowish-brown and with whitish spots.
It may be remarked that the basal nerves of the leaves are
sometimes much more oblique, more conspicuous, and more
produced towards the apex than the others, giving the leaf
the appearance of being triplinerved; but, as a rule, the
lateral nerves are more or less parallel and uniform. In
the wild state the sand pear was found by Maack, Maximo-
wicz, and others in the vaileys of the southern tributaries of
the lower Amur and the Manchurian littoral. Here the
fruit is smaller and very astringent.

Descriprion.— Tree, 30-40 ft. high, with glabrous or
fugaciously hairy branchlets which at first are of a warm
brown or purplish colour, but at length turn dark or
greyish-brown. Leaf buds glabrous, ovoid, with very acute
scales. Leaves ovate from a broad base, acuminate, densely
serrate, the teeth running out into fine almost bristle-like
points which may at length fall off, 2-4 in. long, 14 to
over 2 in. broad, subcoriaceous, of a rich green when
mature, long persistent, glabrous or when young more or
less covered with a cobwebby brownish tomentum, particu-
larly along the edges and midrib; petiole 1-2 in. long;
stipules subulate, ciliate. Flowers in 4—9-flowered corymbs
on sparingly leafy short shoots ; pedicels glabrous or more
or less hairy, sometimes almost 2 in. long. Calyx like the
receptacle, glabrous or cobwebby, woolly without, always
woolly within; sepals ovate-lanceolate or triangular, denti-
culate. Petals white, obovate to ovate, 2-3 in. long.
Anthers purple. Fruit in the wild plant globose with a sub-
persistent calyx, olive-brown with numerous lenticels, 1 in.
in diameter, in the cultivated plant much larger, as much
as 3 In. across, and sometimes obovoid.—Orro Srapr.

Cuitivation.—This interesting pear has been cultivated
at Kew since 1875. In the spring of that year a valuable
collection of grafts of Pyrus was presented to Kew by the
late Prof. Decaisne. It was from one of these that the
plant now figured was raised. It flowers freely almost
every year early in April, but rarely produces a large crop

of fruit. This species thrives very well in the ordinary soil
of Kew.—W. J. Bran.

Evupatorium, Linn.; Benth. et Hook. f. Gen. Plant. vol. ii. p. 245.

Eupatorium Raffillii, Hems/., species ex affinitate H. tanthini, Hemsl. (Hebe-
clinium ianthinum, Hook., B. M. t. 4574), a quo inflorescentia araneoso-
tomentosa, capitulis majoribus subumbellatis et involucri_ bracteis
paucioribus differt ; etiamque JL. sordido, Less., arcte affinis, a quo foliis
cito glabrescentibus et capitulis majoribus subumbellatis recedit.

Frutec 0'5-1 m. altus, ramis rectis teretibus primum rubro-brunneis
tomentosis. Folia opposita, longe petiolata, crassiuscula, ovata basi
* rotundata vel inferiora oblanceolata, basi cuneata, absque petiolo 12-15
em. longa, 7-10 cm. lata, acuta, supra basin quintuplinervia, primum
utrinque parce obscureque setulosa, margine minute calloso-denticulata ;
petioli teretes, 3-8 cm. longi. Capitula numerosa, circiter 2 cm. diametro,
in cymas compositas terminales erectas subglobosas 10-15 cm. diametro
dispositi; pedunculi breves, rigidi, ferrugineo-tomentosi vel lanati, sub-
umbellati. Involucri bracteae circiter 40, 3-4-seriatae, tenues, rubro-
brunneae, hirsutae, lineares, exteriores breviores, filiformes, omnes acutae,
interiores corollis aequales. Corollae lilacinae, omnes tubulosae; tubus
supra medium inflatus, lobis parvis piliferis. Stamina inclusa. Styli
longissime exserti. Achaenia glabra; pappi setae molles, albae, quam
corolla tertia parte breviores.—Hebeclinium ianthinum, Hort. nonnull.,
non Hook.

The history of the introduction of this Eupatorium into
cultivation is not known. Mr. C. P. Raffill, of the tropical
department at Kew, who procured a plant of it from the
Birmingham Botanic Garden, called attention to it as being
different from £. (Hebeclinium) ianthinum, under which
name it was there grown. Whether it be really an unde-
scribed species, it is difficult to say. It is certainly very
near the two species with which it is compared above, and
is also very near a specimen in the Kew Herbarium,
collected at Cuernavaca, Morelos, Mexico, by C. G. Pringle,
n. 8048, issued as “ FL. subtriplinervium, K1.,” doubtless in
error for E. septuplinervium, Klatt, published in Leopoldina,
1884, vol. xx. p. 90, where Hebeclinium sordidum and #.
macrocephalum, Schulz-Bip., non Benth., are given as
synonyms.

DecEMBER, 1908,

Description.— Shrub, 13-3 ft. high. Branches straight,
round, clothed with a red-brown felt when young. Leaves
opposite, on long stalks, rather thick, almost fleshy, base
ovate and rounded or sometimes lanceolate and wedge-
shaped, 44 to 6 in. long without the stalk, 24 to 4 in.
broad, acute, 5-nerved above the base, at first sparsely
furnished with small bristles, margin minutely toothed ;
stalks round, 1} to 3 in. long. ower-heads numerous,
nearly 1 in. across, in terminal, erect, compound clusters,
4 to 6 in. across; stalks umbellately arranged. Sracts of
the involucre about 40, in 3 or 4 series, thin, hairy, red-
brown, linear, outer ones shorter, filiform, all acute, inner
ones nearly as long as the corollas. J Vowers all tubular,
lilac. Stamens included. Styles exserted, very long, filiform,
divergent. Achenes very small, glabrous; bristles of the

pappus soft, white, about a third shorter than the corolla.—
W. Borriva Hemsiry.

Cuurivation.—This species has long been cultivated in
the Birmingham Botanic Gardens under the erroneous name
of Hebeclinium ianthinum. It is, however, superior, in a
decorative sense, to . (H.) ianthinum, the heads of flowers
being fuller and richer in colour, while the leaves also are more
handsome. It grows quickly into a shapely specimen 2 ft.
or so high and is in full flower in mid-winter. Although
it will grow and flower in an ordinary greenhouse this plant
is seen at its best under good cultivation in a tropical house.
Cuttings rooted in early summer and grown on in pots in a
moist stove quickly grow into handsome specimens; they
last in flower a month or more—W. Warson.

The genus Gesneria, the type of the family Gesneriaceae,
was founded by Linnaeus on two West Indian species,
G. humilis and G. tomentosa, published in his Species
Plantarum, ed. 1, 1753, p. 612. During the succeeding
70 years many additional species were described, and it at
length became evident that species belonging to several
distinct genera were included under Gesneria. Martius
(Nov. Gen. et Sp. vol. iii. 1829, p. 27) accordingly dis-
tinguished three genera, one of which was based on G.
humilis, and a second on G. tomentosa, whilst the third
included the great majority of the described species, namely,
those provided with tuberous rootstocks. Instead of.
retaining the name Gesneria for one of the original species,
Martius proposed the new generic names Conradia and
Rytidophyllum for G. humilis and G. tomentosa, respectively,
and applied Linnaeus’s generic name, modified to Gesnera,

Drcemser, 1908,

to the subsequently described species possessing tuberous
rootstocks. By common consent among botanists the name
Gesneria is now retained for G. humilis and its allies, and
Rytidophyllum for G. tomentosa and its allies, whilst the
name Corytholoma is applied to the species with tuberous
rootstocks. The latter are, however, still commonly known
in gardens under the generic name Gesnera, and include the
following which have been figured in this magazine :-—
G. aggregata, t. 2725, Lindleyi, t. 3602, Marchii, t. 3744,
cardinalis, t. 8167, and many others.

The plant of Corytholoma macropodum here figured
differed from those originally raised in having a single pair
of large leaves instead of two pairs of small leaves, and
blotches on the lower lip of the corolla as against small spots
in the original plants. Like many other Gesneriaceae it
appears to be highly plastic and may in time give rise
to garden races unlike the wild species.

Drscription.—Herb, 6-9 in. high, glandular - hirsute,
tuber subglobose, perennial. Stems one or two, annual,
unbranched, bearing one or two pairs of leaves. Leaves
suborbicular, cordate at the base, 3-5 in. in diameter,
obtusely serrate, ciliate, upper surface pilose with short
erect glandular hairs, lower surface with very prominent
hirsute veins, otherwise glabrous ; petioles about 4 in.
long. Cymes solitary, axillary, 5-7-flowered; peduncles
2-4 in. long. Flowers subumbellate, pendulous; pedicels
3-3 in. long. Calyz-tube very short; lobes ovate, acu-
minate. Corolla cinnabar-red, pubescent outside; tube
1 in. or more long, nearly cylindric, with an annular swelling
at the base and slightly ventricose above ; limb two-lipped,
the upper lip consisting of two, the lower of three lobes ;
lobes of lower lip blotched with purple. Glands of the
disk 5, the two posticous ones united in the form of a
horseshoe. Ovary rather densely pubescent; style glandular-
puberulous; placentas bilamellate.—T. A. SPRAGUE.

CULrivaTion.— Corytholoma macropodum was raised from
seeds collected in Sio Paulo, by Mr. G. H. Weigt, Director,
Botanical Parks, Piracicaba, Brazil, and forwarded to Kew
in 1906 with a recommendation of the plant as a good
lecorative species, It grew freely under the treatment

given to other tropical gesneriads and flowered at Kew in
April. There are other Gesnerias with flowers of the same
shape, colour and arrangement as C. macropodum, but none
of those in cultivation have the remarkable bifoliate stems
which characterise this species.—W. Warson.

Eria hyacinthoides, Lindl., is a Javan species which was
originally described by Blume in 1825 under the name of
Dendrolirium hyacinthoides; the two genera _ cannot,
however, be separated. The species was recorded as a
native of Mt. Salak. Lindley probably only knew it from
description, for his herbarium contains but a single flower,
marked as authentic, which was afterwards sent to him by
Reichenbach. The plant here figured was obtained from
Leiden by Mr. F. W. Moore, Glasnevin, under the name of
E. bieristata, Lindl., but that species according to the original —
description has a short, few-flowered inflorescence, and
Mr. J. J. Smith, author of Die Orchideen von Java, con-
siders our plant to be E. hyacinthoides, Lindl.; it certainly
agrees better with the description of the latter. Smith,
however, describes the side lobes of the lip as deep violet
brown, a character not mentioned by Blume. He further
considers FE. ebulbis, Lindl. (Dendrolirium ebulbe, Blume)
and EF. Endymion, Ridl., as synonymous ; this point requires
confirmation, for Blume placed the former in a different
section from £. hyacinthoides, and the latter is a native of

Singapore. Further material is necessary to clear up these
points. Several of the Javan species are very imperfectly
known, and Smith enumerates eight out of thirty-five as
doubtful. ria is a large and difficult genus, bearing a
considerable general resemblance to Dendrobium, from which
it is readily separated by its eight pollinia. The species are
not commonly cultivated except in botanical gardens, and
as the fleshy crests of the lip shrink greatly in drying they
are unusually difficult to discriminate. They are chiefly
concentrated in the Indo-Malayan region.

Descriprion.—LEpiphyte, about a foot high. Pseudobulbs
erect, oblong, somewhat compressed, 24-3 in. long,
clothed with brown sheaths, 2—3-leaved. Leaves petioled,
elongate-oblong, subobtuse, coriaceous, 8-12 in. long, about
13 in. broad, somewhat attenuate at the base. Peduncles
axillary, erect, stoutish, 4-6 in. long; racemes elongate,
many-flowered. Bracts ovate, acute, concave, pubescent,
about 4 in. long. Pedicels about 14 in. long, white-
tomentose as is the rachis. /Vowers pubescent, white, with
a yellow anther. Dorsal sepal oblong, obtuse, over 3 in.
long ; lateral ovate-oblong, obtuse, over 4 in. long; mentum
oblong, obtuse, about 4 in. long. Petals ovate-oblong,
obtuse, about } in. long. Lip 3-lobed, about $ in. long ; side-
lobes erect, triangular, acute; front-lobe reflexed, ovate-
oblong, obtuse; disk with two prominent fleshy keels,
channelled. Column clavate, about + in. long.—R. A. Roure.

_ Cuutivarion—Eria hyacinthoides was presented to Kew
in 1903 by Mr. F. W. Moore, Keeper of the Royal Botanic
Gardens, Glasnevin. It is a sturdy grower and produces in
May several spikes of white flowers which last a long time.
Like the rest of the genus this species enjoys liberal treat-
ment during its growing period, which is from April to
September, and a lower temperature with little or no water
at_ the root during its resting period. It thrives in a
mixture of peat fibre and sphagnum in a pan or teak basket

suspended near the roof glass in the tropical orchid house.—
W. Warson.

Cytisus decumbens has a very wide range in the South of
Europe, extending from France to Albania. It belongs to
the sub-section Corothamnus, Briq., which is chiefly dis-
tinguished by having all the leaves unifoliolate. Two other
species besides the one here figured, C. procumbens, Spreng.,
and C. diffusus, Vis., possess this character, all the others
being trifoliolate. Godron, Fl. de France, 1848, i. p. 360,
indicates three varieties, characterized by the length of the
pedicels and the size of the flowers.

Ducemper, 1908.

Drscriprion.—Shrub, 4-8 in. high, procumbent; young
branches 5-angled, pubescent, at length glabrous. Leaves
unifoliolate ; leaflet sessile, oblong-obovate, rounded at the
apex or slightly acute, narrowed to the base, 1—3 in. long,
3—¢ In. broad, pilose on both surfaces, ciliate, lateral nerves
indistinct. Flowers solitary or two to three together ;
pedicels 3-3 in. long. Calyx subcampanulate, 1 in. long,
two-lipped, lips shorter than the tube, sparingly pilose out-
side; upper lip bidentate; lower lip shortly tridentate,
teeth acute. Standard broadly obovate, many-veined, about
% in. broad, claw } in. long. Wing-petals oblong, 1 in.
long, 6—7-veined, claw 3 in. long. Keel-petals 4 in. long.
Staminal-tube glabrous, } in. long. Ovary villous; style
about } in. long, stigma minute. Pod 4-2 in. long, pilose
on all sides. Seeds 3 or 4, rounded, with a distinct, rounded
strophiole—J. Hurcnrnson.

Cuttivation.—Cytisus decumbens is a charming small
trailer, the stems keeping close to the ground and forming
a cushion not more than 6 in. high, which in May is
studded all over with bright yellow flowers. It may be
grown in a border so as to form a carpet below other taller
shrubs, or in a sunny position in the rock garden. The
Kew examples were originally raised from seeds received in
1895 from the Goettingen Botanic Garden.—W. Watson.

Hibiscus aponeurus belongs to the section Bombycella,
which is characterized by relatively small flowers and
woolly seeds, and includes about forty species, nearly two-
thirds of which are natives of Africa. H. aponeurus is
intermediate, both geographically and in technical characters,
between AZ. crassinervius, Hochst., and #. Hildebrandtii,
Sprague & Hutchinson, and has been found over a wide
area in Uganda, British East Africa and German East
Africa, occurring at elevations of 4,000—-6,000 ft. According
to Grant, it grows both in the valleys and on the hills of
Karagué. :

Comparatively few species of the section seem to have
come into cultivation, among them being JH. phoeniceus,

DecremBer, 1908.

Jacq., figured in the Botanical Register, vol. iii. t. 230, and
H. hirtus, L., l.c. iv. t. 337, as H. Rosa-malabarica. The
former may be distinguished by its long spreading bracteoles,
and the latter by the coarsely serrate, acute, relatively
glabrous leaves.

Descriprion.—Plant erect, shrub-like, 1-4 ft. high;
branches slender, strict, harshly stellate-pubescent. Leaves
ovate or elliptic, sometimes slightly three-lobed, rounded or
obtuse at the apex, rounded at the base, 1-1} in. long,
$-1{ in. broad, serrulate, harshly pubescent on both surfaces,
more densely so below; petioles 4—$ in. long. Stipules
filiform, $-} in. long. Flowers solitary, axillary ; peduncles
over | in. long, jointed } in. below their apex. Bracteoles
9-13, sharply ascending, unequal, linear-subulate, }—4 in.
long, antrorsely hirsute. Calyx densely stellate-hirsute
outside, minutely pubescent inside in the upper part,
glabrous below; tube } in. long, 15-nerved ; lobes subulate
from a triangular base, + in. long, +4, in. broad at the base,
3-nerved, reflexed above. Corolla brilliant scarlet, 1 in.
across, stellate-pilose outside. Staminal column curved,
5-toothed at the apex, bearing 4 alternating whorls of
stamens, the lowest one consisting of 5 single stamens
opposite the petals, the others of 5 pairs each; partial
filaments j, in. long or less. Ovary 5-celled, minutely
whitish tomentose; cells 5—7-ovuled; stigmas capitate,
penicillate. Capsule ellipsoidal, 2 in. long, 3 in. across,
slightly shining, pubescent.—T. A. SPRAGUE.

Cuntivarion.—Hibiscus aponeurus was raised from seeds
collected in British East Africa by Lady Hindlip, who
kindly presented cuttings of it to Kew in 1905. It forms a
neat little shrub, and in June is gay with numerous bright
scarlet flowers. At Kew it has been grown in a warm
house, but it would probably be quite at home under
ordinary greenhouse treatment. Like the majority of the
species of Hibiscus it is very easy to cultivate, thriving in
ordinary soil_—W. Warson.

NOTICE OF RE-ISSUE.

Some portions of the above work being out of print, and complete sets
very difficult to obtain, the Publishers have determined to reprint so
much as will enable them to complete a few copies as they may be
subscribed for ; and to meet the convenience of Subscribers, to whom
the outlay at one time of so large a sum as a complete set now costs
is an impediment to its purchase, they will commence a re-issue of
two Volumes Monthly, thus spreading the cost over a period of
two and a half years. The price of the volumes will be 42s. each as.
heretofore, but to Subscribers for the entire series 36s. each, or a
complete set-of the 60 vols. will be supplied for £100 cash, Subscribers
may commence at any time.

The BoranicAL MaGaAzINE, 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 Txarrp Serizs, 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
by D. Prain, C.I.E., LL.D., F.R.S., Director of the Royal Botanic
Gardens, Kew.
