The handsome Amorphophallus here figured is one of 
several species of the genus obtained by Dr. A. F. G. 
Kerr in the Chiengmai district, Siam, tubers of which 
were forwarded by him to Professor H. H. Dixon for 
cultivation in the Botanic Garden of Trinity College, 
Dublin. The present species, one of the most strikin-z, 
flowered there in March in the years 1910, 1911 and 1912 
and ripened fruits in July, 1915 ; as is not unusual in the 
genus, the J eaves appear after the flowers. For the fresh 
material at its various stages utilised in preparing our plate 
we are indebted to Professor Dixon. Mr. S. G. Wild, 
whose enthusiasm is so well known, and to whom the care 
of the tubers was intrusted, informs us that A. Kerrii is best 
grown in a compost consisting of two parts good loam 
with one part each of leafsoil, peat and sand. It requires 
ample pot-room, a genial atmosphere and a temperature 

January, 1917. 



ranging from 65° to 70° F. during the growing season. 
Corms potted at the beginning of March flower in April 
and May, when adequate water should be supplied till 
about the end of September, an occasional application 
of liquid cow manure being beneficial. After September 
the pots may be stored in heated frames with a minimum 
temperature of about 45° F., and should be kept quite 
dry. The corms are readily increased by offsets, and if 
one is fortunate enough to fertilize the flowers, seeds may 
be obtained which, if sown as soon as ripe, produce new 
corms which should flower about their third season.

The Portugal White Broom, here figured, a native of 
northern and central Spain and Portugal, has had a 
somewhat chequered cultural history. Whether it be, 
as Lamarck and others have thought, the Genista alba 

Januaky. 1917. 



figured by Tabernaemontanus in 1538, seems open to 
doubt ; L'Escluse, whose Spanish notes were published 
in 1576, does not allude to the species, and Tabernaemon- 
tanus has not recorded the native habit of his plant. 
Tournefort, who met with this broom in Portugal in 
1688, named it Cytisus lusitanicus foliis minimis argenteis 
parvoflore albo, and sent a specimen to Bobart, who iden- 
tified both it and some specimens of Retama monospermy 
Boiss., with the Genista alba of Tabernaemontanus. The 
specimen given by Tournefort to Bobart is still in the 
Morison herbarium at Oxford, but that the plant had 
not been introduced to English gardens in 1699 when 
Bobart wrote, seems clear from the fact that there is no 
reference to it in the works of Ray. The earliest record 
of its cultivation in this country occurs in the third, or 
1739, edition of Miller's Dictionary, where, as well as in the 
three subsequent issues of that work, it is given as the 
Portugal Base-Tree-Trefoil ; in the second edition of the 
Hortus Kewensis, the younger Aiton, in 1812, refers to 
the circumstance that it was grown by Miller as recently 
as in 1752. Shortly thereafter the plant would seem to 
have been lost to English gardens ; it is not included in 
the seventh edition of 1759, or in any later issue of 
Miller's work; moreover, the elder Aiton, in the first 
edition of the Hortus Kewensis, in 1789, treated it as 
a new Spartium, S. multiflorum, which he termed the 
Portugal White Broom, introduced to this country by 
Mr. James Gordon about 1770. Since this second intro- 
duction the plant has persisted in our collections ; indeed, 
in 1812, a third introduction took place, this time of a 
form which is, however, but an unstable colour-variant, 
m which the flowers are flushed with pink. According 
to Loddiges, this form with incarnate blos-:oms was 
raised from seeds by Thomson at Mill-end; Loddiges, 
however, adds that " it may be increased by seeds which 
are perfected in abundance, but the produce are not all 
pink-flowered." Indeed, as our illustration shows, sprays 
with white flowers and others with the petals tinged with 
pink may at times be present on the same plant. That 
the Portugal White Broom is, as Tournefort had decided, 
& Cytisus, is not open to doubt, and Willkomm has stated 
that Quer, who accepted this view, actually named it 



C. lusitanicus in conformity with Linnean principles. In 
the supplement to his Spanish flora Willkomm has 
accordingly adopted this obviously apposite name, and 
in this he has been followed by recent Spanish and 
Portuguese authors. Willkomm, however, has not cited 
the passage in which the name C. lusitanicus, Quer, 
occurs ; the name is not employed in the Flora Espaiiola 
published by Quer in 1762 and completed by Ortega in 
1784. In 1789 Lamarck, adopting the view of Bobart, 
treated this broom as a Genista, so that the name G. alba, 
Lamk, is the earliest verifiable one applied in conformity 
with modern usage. Unfortunately, long before Link, 
in 1822, retransferred the species to Cytisus, another 
C. alius, from south-eastern Europe, had in 1790 been 
duly described by Haquet. Meanwhile the elder Aiton, 
in 1789, had placed the Portugal White Broom in 
Spartium, as S. multiflorum ; so that when Sweet, in 
1826, corrected this error the species was transferred to 
Cytisus as C. multifiorus. In order to avoid the con- 
fusion created by the fact that the name C. albus had 
been used for two different brooms from south-eastern 
and south-western Europe respectively, recent writers, 
following Briquet, who has monographed the genus 
Cytisus with singular care, have felt constrained to 
employ for the Portugal White Broom the name C. 
multiflorus, Sweet, rather than the name C. albus, Link. 
In his monograph of the genus, however, Briquet has 
indicated that the plant described by Haquet, for which 
in 1803 Waldstein and Kitaibel proposed the name 
C. leucantlius, under which it was figured at t. 1438 of 
this work, is better treated as referable to C. supinus, 
Linn. So long, therefore, as the validity of the name 
C. lusitanicus, Quer, employed by Willkomm in 1893, 
remains doubtful, it is possible to follow Schneider in 
retaining for the Portugal White Broom the name 
C. albus under which, since the time of G. Don and 
Loudon, it has been familiarly known in English 
gardens. Among the cultivated brooms C. albus is dis- 
tinct and valuable in being the only really hardy species 
with white flowers. ' Others with flowers of a similar 
shade are more or less tender; C. albus, even in very 
hard weather, remains unscathed, or at most only suffers 



an occasional cutting back of the young succulent 
growths. Planted in broad masses at Kew, where it has 
been in continuous cultivation since the time of the elder 
Aiton, it gives charming effects when in bloom in May. 
It does not need a rich soil, and as it ripens seed in 
abundance it is easily increased. The material for our 
plate was derived from a plant in the collection at Kew, 
with mixed white and pink-flushed flowers. 

Description. — Shrub, of upright habit, 5-7 ft. high, moderately branched,

This variety of Cotoneaster salicifolia was discovered by 
Mr. E. H. Wilson on the mountains of Western Hupeh 
at altitudes of 5,000 to 6,000 feet both to the north and 
south of Ichang. From seed collected by him in October, 
1907, and received at Kew through the agency of the 
Arnold Arboretum the following spring, the plant now 
figured was raised. Since its introduction the winters 
have been mild and it has proved evergreen, but it is 
possible that, as with some other ordinarily evergreen 
Cotoneasters, its foliage may prove deciduous in our 
hard winters. It likes a sunny position and a loamy 
soil, and being very amenable to cultivation promises to 
develop into one of the finest members of the genus in 
gardens. It is easily increased by seed or by cuttings. 

January, 1917. 



From the typical C. salicifolia, which we are not certain 
is at present in cultivation, the variety now figured 
differs in the leaves being broader and duller green, and 
in the'r lower surface as well as the young branchlets 
being covered with a coarser, more woolly pubescence. 
Another variety, C. salicifolia var. floccosa, Rehd. et Wils., 
is cultivated at Kew, and is well distinguished by its 
narrower leaves and three-stoned fruits. The nearest 
ally of C. salicifolia' is C. Henry >ana, Rehd. et Wils., also 
from Western Hupeh ; this differs by its ovoid fruits and 
larger leaves pubescent on both surfaces. 

Description.— Shrub up to 10 ft. high of graceful habit, branches spreading. 
Branchlets slender, at first clothed densely with a pale brown wool, most of 
which falls away by autumn exposing the handsome, dark reddish-brown bark. 
Leaves stiff and coriaceous, persistent, oval to slightly obovate, acute, cuneate 
at the base, entire, 1^-3 in. long by ^-1^ in. wide ; dark dull green, rugose and 
glabrescent above ; at first wholly lanuginose beneath, ultimately greyish- 
white, with wool on the midrib and veins only ; veins in nine to eleven pairs, 
deeply impressed above ; petiole ^\-\ in. long, lanuginose. Corymbs 1-2 in. 
wide, terminal on 2-4-leaved branchlets. Flowers dullish white, opening 
in June, i in. wide. Calyx woolly, funnel-shaped, with five short, erect, 
acute, triangular lobes. Petals five, rotund. Stamens about twenty ; anthers 
brownish-red. Fruit globose to slightly ovoid, \ in. wide, bright coral red; 
stones 2, compressed-hemispherical, grooved on the dorsal side.

January, 1917. 



Quercus densifiora was first discovered by David 
Douglas. His specimen in the Kew Herbarium is not 
precisely localised, but according to Hooker and Arnott it 
was in the Californian collection made by Doudas chiefly 
at Monterey and San Francisco. From Professor Sareent 
we learn that the species is distributed from the valley 
of the Umpqua River in Southern Oregon southward 
through coast ranges to the Santa Inez Mountains east 
ot Santa Barbara, California, and along the western 
s opes of the Sierra Nevada to Mariposa County. In 
the Sierra Nevada it ascends to an elevation of 4 000 
feet above sea-level. It is exceedingly abundant in the 
humid Cahfornian coast region north of San Francisco 
±5ay and attains its largest size in the Redwood forests 
01 Napa and Mendocino Counties. The species is very 
variable in habit and in its leaves, sometimes occurring 
as a low spreading shrub only 1 to 10 ft. high, with small 
entire leaves. This has been distinguished as var 
echinoides Sargent (= var. montana, Mayr = Q. echinoides, 
R. -Br., Campst.). Pasania densifiora, forma lanceolata, 
Jepson, Silva Calif. 237, has lanceolate entire or nearlv 
entire leaves 2±-3 * in. long. 

The wood of this oak, though hard and strong, is 

brittle and is of little value except for fuel, but its bark 

is very rich in tannin and is used in enormous quantities 

inn-7 ^ nmg leather - Professor Jepson states that in 

1907 the annual tan harvest was about 25,000 cords and 

to obtain this amount 100,000 trees were sacrificed e'verv 

year, most of them being left in the forest to decay or 

to be consumed in the first forest fire. Best known as 

the Ian Oak it is sometimes called Burr Oak and often 

Chestnut Oak, and locally Squaw Oak and Sovereign 

Uak. The species is of great interest as being the 

solitary representative in the New World of the section 

lasama, often regarded as a genus distinct from Quercus, 

which comprises about 100 species nearly all of which are 

confined to South-eastern Asia. Its dense erect or sub- 

erect catkins, resembling those of Castanea, small anthers 

with pollen-grains much smaller than in Quercus proper, 

and woody thick pericarp are salient characters by which 

it may easily be distinguished from all other American 

oaks. 



Notwithstanding the unusual interest of this tree it is 
one of the rarest of cultivated oaks. Two trees at Kew, 
if we except some young plants recently raised, appear 
to be the sole representatives of Q. densi flora in this 
country. From the larger of these material for our 
figure was obtained. This tree was raised from a packet 
of acorns received from Professor Sargent in 1 874, and is 
growing in the Oak Collection near the southern end of 
the Rhododendron Dell. In some respects Q. demiflora 
is the most attractive of all the hardy evergreen oaks. 
The young leaves are covered on the lower surface with 
a thick tomentum which is at first milk-white, becoming 
tawny with age. The stout parallel ribs are also very 
distinctive. The tree is very leafy, almost luxuriant in 
aspect, yet it is slow-growing, and the larger of the two 
specimens at Kew, now over forty years old, is only 
27 J feet high, its trunk at 3 feet from the ground being 
2| feet in girth. In July, 1897, this tree was 14 feet high 
and 7 inches in girth. Like all oaks, Q. demiflora likes 
a good loamy soil. It transplants extremely badly — a 
fact which may help to account for its rarity. It is 
safest to grow it in pots until it is large enough to plant 
out in a permanent place, which should be done as soon 
as possible. Care must also be taken that its roots do 
not become pot-bound. Its leaves persist for three or 
four years, and its fruits ripen at the end of the second 
year. These, however, cannot be relied on in this 
country for propagation. It must be raised in the first 
instance from imported seeds. 

Description. — Tree, often 50-80 ft., sometimes 100 ft. high, trunk usually 
3£ ft., occasionally 5 ft. thick ; branches ascending or spreading ; twigs at first

The fine Rhododendron here figured is a native of 
western Hupeh, where, according to Mr. E. H. Wilson, 
to whose efforts its introduction is due, it is the common 
species of wocds up to an elevation of 8,000 feet. It is 
readily recognised, in the group with glabrous leaves to 
which it belongs, by its large white flowers with glabrous

filaments and rather densely glandular style. In beauty 
and fragrance it is equal to any of its immediate allies, 
and is fuither readily distinguished from these by 
the valuable cultural character of being the latest in its 
group to flower. As compared with the related It, For- 
tuneiy Lindl., figured at t. 5596 cf this work, which 
flowers in May, E. discolor dees not come into blossom 
until the middle of June, a season when few Rhododen- 
drons of either wild or garden origin are to be found in 
bloom. Our plant also possesses another character 
valuable in this country, in being late of starting into 
growth; with the exception of E. auriculatum, Remsl., 
from Central China, it is probably the latest. This 
renders it free from the danger of late frosts ; so far as 
ordinary winter cold is concerned it is also perfectly 
hardy. The plant which provided the material for our 
plate was raised at Kew from seed collected by Wilson 
in autumn in 1908, received from the Arnold Arboretum 
early in 1909. 

Description.— Shrub of robust habit, 6-8 feet high ; terminal twigs cylindric, 
about -| in. thick near the tips, glabrous, somewhat polished. Leaves large, 
elongate- or oblong-elliptic, obtuse with a mucronate tip, base rounded, 6-12

with the spaces enclosed within the reticulations slightly raised ; midrib flat 
above, very visible towards the base beneath and there nearly £ in. wide, 
gradually narrowed upwards ; lateral nerves 15-18 along each side, slender, 
sunk above and rather indistinct beneath, much branched towards the leaf-

This attractive plant was discovered by Mr. C. A. 
Purpus in the Sierra de Mixteca, Oaxaca, Mexico. He 
saw it in only one locality, and that was on the slopes 
of the Cerro de la Yerba, growing on limestone rocks 
and on the walls of old ruins. As seen in nature, with 
its growths hanging over the rocks and bearing numerous 
showy flowers, it presented a striking object. Seeds 
were sent to the Darmstadt Botanic Garden, from which 
some were received at Kew in 1912, and plants raised 
from these flowered in the Temperate House for the first 
time in July, 1915, supplying material for the present 
illustration. In the original description the peduncles 
are said to be only about two inches long, and the 
photographs in Mollers Deutsche Gartner-Zeitung of 

February, 1917. 



plants which flowered in the nursery of Mr. Herb of 
Naples represent peduncles about as long as the petioles, 
though in the text the flowers are described as being 
long-stalked. The peduncles iu the Kew plants were 
three to four inches long. This is probably due to indoor 
cultivation. Mr. A. Purpus recommends the plant for 
sunny, dry places. Protected from wet, the tuberous 
rootstocks survived the winter out of doors at Darmstadt. 
The species is described as non-climbing. At Kew the 
stems have reached a length of about 3 ft. and do not 
show the tendency to climb by means of the petioles met 
with in most Maurandias ; M. Purpusii differs markedly 
in this respect from its close ally, M. eruhescens. Only 
one species, M. erecta, Hem si., so far as is known, has a 
distinctly erect self-supporting stem. The genus Mau- 
randia comprises eight species (or seven if M. geniculate 
Robinson & Fernald, be referred to M. erecta, which it 
resembles very closely) all of which are natives of Mexico, 
one, M. WiMizenii, Engelm., extending to New Mexico. 
M. eruhescens and M. semperjlorens, Ort., have become 
naturalised in some of the West Indian Islands and in 
some parts of Tropical America. These two species and 
M. scandens, A. Gr., are figured in this Magazine at 
tt. 460, 3037, 3038 and 3650. 

Description.— Herb, perennial, shortly glandular-pubescent ; base of stem 
and roots thick and fleshy. Stem slender, ascending or prostrate, hardly 
scandent, 3-4 ft. long. Leaves alternate, petioled, wide triangular-ovate, 
acube, base deep-cordate, irregularly toothed or crenate, at times nearly entire, 
U-lf in. long, 1A-2 in. wide at the base; petiole l$-lf in. long. Flowers 
showy, long-stalked, solitary in the upper axils ; peduncles ascending, slender, 
3-4 m. long, usually longer than the leaves. Calyx herbaceous, 5-partite 
almost to the base; lobes oblong-ovate, rather rounded and apiculate, base 
cordate, about f in. long, } in. wide. Corolla bright rose-purple, 1J-1 \ in. 
long almost glabrous externally ; tube narrow-funnel-shaped, slightly swollen 
at the base in front, glandular-pubescent within, especially at the base ; limb 
patent, 2-hpped, almost equally 5-lobed, about 1 in. across ; lobes suborbicular, 
about I m. wide. Stamens 4, in two pairs, hardly exerted ; filaments densely 
glandular-pubescent. Ovary conical, glandular-pubescent like the style which 
is shorter than the stamens and is entire at the tip. Capsule ellipsoid, rounded 
above unequal at the base, about i in. wide, rather shorter than the calyx, 
tipped by the persistent style. Seed almost orbicular, about 4 in. wide, tuber- 
culate, with a surrounding emarginate, striate, toothed or sinuate wing.

The genus Senecio is represented in New Zealand by 
some thirty species which vary in habit from small 
weeds resembling the Groundsel of our gardens to much- 
branched shrubs with leathery leaves like S. Monroi, the 
subject of our illustration. This species, which is con- 
fined in a wild state to the South Island of New Zealand, 
where it flowers from December to January, along with 
a few others bears considerable resemblance in habit 
and appearance to some of the species of Olearia, 
Moench, so characteristic of New Zealand, but is readily 
distinguished by the fewer involucral bracts as well as by 
the different style-arms, which in Olearia exhibit the

characters that mark the tribe Asteroideae. S. Monroi 
was first sent to Kew in 1905 by Mr. G. Matthews, 
Dunedin ; at Kew it is grown in the cool greenhouse and 
flowers in autumn. The material for our figure came 
from the garden at Ludgvan Rectory.. Long Rock, 
Cornwall, where, the Rev. Mr, Boscawen informs us, it 
was raised by him from seed sent to him from New 
Zealand in 1907. At Ludgvan the plant grows well in 
any ordinary garden soil and flowers freely; some of 
Mr. Boscawen's examples are now compact bushes three 
feet in height and about four feet through. 

Description.— Shrub, much branched, 6-7 ft. high; twigs densely leafy, 
shortly -white woolly. Leaves petioled, oblong or oblong-lanceolate, obtuse, 
gradually narrowed to the base, f-1 in. long, about 4 in. wide, margin

The Urticaceous genus Pilea includes over two hundred 
species dispersed throughout the tropics of both hemi- 
spheres. Of these the best known is the tiny P. muscosa, 
Lindl., the * gunpowder plant,' so-called from the cloud 
of pollen discharged from the anthers when the plant is 
shaken—a common South American species which has 
become introduced into India, and even into Australia 
where alone no native Pilea occurs. Very few species 
are in cultivation, the only ones to be met with in 
collections so far being P. ijrandis, Wedd., a native of 
Jamaica, with large green, dentate leaves in shape 
recalling those of a Coleus, and P. Spruceana, Wedd., 
a native of Peru, with ovate dark bronze-green foliage. 
To these have now to be added the attractive foliage 

February, 1917. 



plant which is here figured. This species, P. For.geti, 
was discovered in Venezuela by Mr. L. Forget in 1914, 
when collecting on behalf of Messrs. F. Sander and Sons, 
St. Albans, by whom it has been introduced to culti- 
vation. The dwarf habit with bright bronze foliage 
striped with green give it a pleasing appearance when 
out of flower. The sexes are distinct, and in the case of 
the female plant, in which the flowers are inconspicuous 
and hidden away in small dense clusters in the axils 
of the leaves, the general facies of the plant remains 
unchanged. In the case of the male, however, flowering 
adds to the charm of the plant owing to the develop- 
ment of pairs of dense clusters of small white flowers 
raised on long pink stalks well above the foliage. Like 
the few species already in cultivation, P. Forgeti is 
easily grown in a tropical house, and like them sets seeds 
in abundance.

The handsome Anguloa here figured was introduced to 
cultivation by Messrs. Charlesworth and Company, 
Haywards Heath, in whose nursery it flowered in July, 
1910, the plant passing into the collection of Mr. J. 
Talbot Clifton, Lytham Hall, Lancashire, to whom it 
was dedicated in the original description. A few years 
later a fresh importation was effected by Messrs. F. 
Sander and Sons, St. Albans. This species, A. Cliftoni, 
differs markedly from the previously known members of 
its genus in having a deeply saccate base to the lip, which 

March, 1917. 



has a narrow strongly recurved frontal lobe, and in the 
shorter column which is constricted below the apex and 
much swollen above the base. The locality of the 
original plant has not been stated, but the species 
is known to occur in the district of Antioquia in Colombia. 
The material for our figure has been obtained from a 
plant imported by Messrs. Sander. Like other members 
of the genus, A. Cliftoni thrives in the intermediate house. 
It is most suitably grown in a compost of turfy loam 
and peat, with a small proportion of chopped sphagnum 
added to the mixture. During the growing season the 
plant requires a liberal supply of moisture at the roots 
and should be kept shaded from bright sunshine. When 
at rest only sufficient water should be given to keep the 
pseudobulbs plump; the plant may then be given a 
brighter and more airy situation, thus ensuring the 
ripening required to induce satisfactory flowering. 

Description. -Herb, terrestrial, 1-1 J ft. high; pseudobulbs clustered, ovoid- 
oblong, 4-6 in. long, lf-2f in. wide, 2-3-foliate. Leaves elliptic -oblong, shortly 
acuminate, margin slightly wavy, plaited, narrowed to the base, 6-12 in. long, 
3-3 1 m. wide. Scapes erect, rather stout, 8-10 in. long, clothed with large, 
spathaceous, somewhat imbricate sheaths; bracts elliptic-lanceolate, acute, 
concave, 2-2J m. long. Flowers large, subglobose. Sepals : posterior elliptic- 
oblong, somewhat obtuse, incurved, very concave, about 4 in. long, 2 in. wide ;

The Barbery here described is one of a group of Chinese 
forms with dull foliage, among which Berberis Wilsonae, 
Hemsl., figured at t. 8414 of this work may be regarded 
as the type, but which includes also the very closely 
allied B. subcaulialata, C. K. Schneider. The species 
now figured was originally described by Dr. Schneider as 
B. Stapfiana from a plant in the Barbery collection at 
Kew, which had been presented by Mr. M. L. de Vilmorin 
in 1910 under the name B. subcaulialata, from which it 
differs in the characters pointed out by Mr. Hutchinson. 
The plant from which our illustration has been prepared 
is not, however, the original type of B. Stapfiana, but 

March, 1917. ^ 



one raised from seed collected by Mr. E. H. Wilson sent 
to Kew in 1909 from the Arnold Arboretum. The seed 
in both instances came from Western China ; the precise 
locality is not known in either case. The long arching 
shoots, which are produced annually, impart to our 
plant a free and graceful habit; its being practically 
an evergreen affords an additional merit; it attains 
its greatest beauty in the fruiting condition, in October 
and November, later in the year perhaps than is the case 
with any other Barbery. It likes a good loamy soil and 
a sunny position ; the abundant seeds render its propa- 
gation easy. How far the differences between the three 
plants with dull-grey foliage above alluded to may be 
specific seems open to doubt. In a recent communica- 
tion Dr. Schneider has suggested that possibly both 
ot the forms described by him as distinct may be 
w?? tleS ° f the s P ecies described by Mr. Hemsley. 
While there is much to favour this view, the fact remains 
that B. Witeonae, Hemsl., is readily distinguished by its 
downy twigs from the two plants described by Dr. 
Schneider, in both of which the twigs are devoid of 
hairs; of these two, B. Stapjiana differs further from 
B. Wilsonae as regards the form of its ripe fruits. 

Description.— Shrub, about 5 ft. high; stem long, branches arching, 
ridged ; twigs glabrous, tawny-purplish, finely pustulate or smooth ; spines 
d-partite from the base, slender, very acute, tawny-straw-coloured, distinctly 
channelled beneath, f-f in. long, the lateral diverging from the main spine at a 
right angle. Leaves in clusters of 4-8, falling late, so that the plant is almost 
evergreen, Imear-oblanceolate, usually sharply mucronate, narrowed below into 
a short petiole entire or rarely 2-3-toothed, J-l* in. long, *-4 in. wide, firmly 
chartaceous glabrous, conspicuously reticulate especially on the green upper 
surface, below somewhat pruinose and papillose. Inflorescences of short

The Clematis which forms the subject of our illustra- 
tion is a native of western Szechuan, where it is found 
in woodlands, but w here it appears to occur somewhat 
sparingly. At one time thought to be a distinct species, 
C. Souliei, Franch., it has recently been regarded as only 
a form of C. Fargesii, Franch., also a native of south- 
western China, and indeed to differ but slightly from 
that plant, as originally described, in having filaments 
considerably longer than the anthers, and perhaps also 
in having the leaflets more rounded or more widely 
cuneate at the base. C. Fargesii is a member of the 
Vitalba group of species ; within that group it is readily

distinguished by its one- or two-flowered ' axillary 
peduncles and by its large and conspicuous flowers. 
The plant from which the material for our figure was 
obtained was raised at Kewfrom seeds received from the 
Arnold Arboretum in 1912. It flowered for the first time 
in 1915 ; the specimen figured Was gathered in 1916. 
Plants continue in flower from June to September ; they 
grow vigorously in a loamy soil, give every evidence of 
being hardy in our climate and develop sufficient seeds 
to make propagation easy. As a climbing shrub for 
gardens this Clematis will be valued for the pure white- 
ness and delicate satiny texture of its flowers. 

Description. — Shrub, climbing; twigs sulcate, shortly tomentose when 
young, ultimately sparingly pubescent, reddish -purple. Leaves 2-ternate, up 
to 8 in. long, 6 in. wide, thinly chartaceous, sparingly adpressed-pubescent on 
both surfaces ; lateral leaflets much smaller than the terminal, more or less 
ovate, |-1$ in. long, J-| in. wide, unequally lobulately toothed or at times 
almost lobate, the teeth ovate, acute and mucronate ; end-leaflet sessile or 
petiolulate, ovate-lanceolate, almost 3-lobed, acutely acuminate, base rounded 
or shortly cuneate, 1J-2 in. long, £~lf in. wide ; nerves sunk above, raised 
beneath, ascending, laxly branched. Peduncles axillary, 1-2-flowered, usually 
much shorter than the leaves, bracteolate above the middle, sparingly 
pubescent, the bracteoles very small, opposite ; pedicels beyond the bracteoles 
1-1J in. long, slender. Buds ovoid, blunt, § in. long. Sepals 6, white, tinged 
outside with yellow, obovate, sharply mucronate, 1-1 \ in. long, f-1 in. wide, 
shortly pubescent externally. Stam ens glabrous, rather longer than the styles ; 
filaments linear, flattened, about \ in. long, nearly thrice as long as the pale 
yellow anthers. Advenes numerous, wide-ovoid, compressed, glabrous, narrowed 
at the tip into the densely villous style.

The very distinct and somewhat peculiar Mesembryan- 
themum here figured was first met with in January, 1907, 
at Moutons Vley, near Piquetberg, Cape Colony, at an 
elevation of about 2,000 feet above sea-level. It has 
since been introduced to European collections by its 
discoverer, Mr. N. S. Pillans. The species has not yet 
flowered at Kew, and the material from which our plate 
has been prepared was obtained from a plant presented 
by Mr. Pillans to the Cambridge Botanic Garden in 1913 
which flowered there for the first time in June, 1914. 
Mr. R. I. Lynch, to whom we are indebted for this 
material, informs us that the conditions suitable for other 
members of the genus meet the requirements of M. Pil- 
lansii. The nearest ally of M. Pillansii is M. lactrum, 
Haw., which it much resembles in foliage, but the very 
remarkable spathulate petals at once distinguish our

The Strawberry-Raspberry is a fruit which, during 
recent years, has attracted attention for its handsome 
appearance, though, in spite of its being sweet and 
palatable, it is somewhat disappointing as regards 
flavour. It is a Rubus with a herbaceous stem which in 
summer attains a height of eight inches, but in winter 
dies down to the ground. At Kew it is quite hardy, 
thriving well in loamy soil and in full sunshine. It may 
be propagated by seeds or by division of the old plants 
in early spring. The history of this Rubus is rather a 
confused one. There is a figure of the plant in the 
Phonzo Zoufou which is characteristic and unmistakable. 
In 1872 Mr. Maximowicz referred to the presence in 

April, 1917. 



Japan of two forms of R. rosaef alius, Smith ; one of 
these, termed alpina, has 1-2 terminal flowers on its 
dwarf young stems, with fruits an inch long; it was 
suggested that this form might be the doubtful R. chinensis, 
Ser., described in 1825. That this is not the case is shown 
by the comparison of our material with a fragment and 
with a natural-size photograph of the original specimen 
of R. chinensis kindly presented to the Kew collection by 
Mr. C. de Candolle ; R. chinensis is a shrub, nearly allied 
to R. rosaef alius, which was collected in China by Sir G. 
L. Staunton, the type specimen of which was presented 
to Mr. A. P. de Candolle by Mr. A. B. Lambert. Some 
time later than 1872 the Strawberry-Raspberry was 
introduced into American gardens and grown as R. sorbi- 
fohus. It subsequently reached Europe under this name, 
as a plant of somewhat doubtful origin, though probably 
Japanese. In 1899 Dr. Focke proved that the plant is not 
R. sorbifolius, Maxim., and described it as a new species, 
R. illecebrosus, allied to the western Chinese R. xantho- 
carpus, Bur. & Franch., without, however, indicating 
its identity with Maximowicz's alpine form of R. rosae- 
fohus and with the Phonzo Zoufou plant. Still later 
Dr. J. H. Wilson, overlooking Focke's account, referred 
to our plant as R. rosaef alius, " better known in gardens 
as R. sorbifolius, the so-called Strawberry-Raspberry." 
Modern Japanese authors, apparently equally unaware 
of the existence of the name R. illecebrosus, consistently 
treat our plant as a dwarf mountain form of R. rosae- 
folnts, notwithstanding the evidence to the contrary 
which its herbaceous habit affords.

Among the thirty species of Senecw which are native 
in New Zealand one of the finest is S. Hectori, the 
subject of our plate. It is readily distinguished from 
its New Zealand congeners by its foliage, the basal 
portion or petiole of the lower leaves being pinnately 
lobulate, while the remainder of the leaf-blade is repand- 
dentate. This species is apparently confined to the 
bouth Island where it occurs in the Nelson and West- 
land districts, at elevations of from 250 to 3,£00 feet 
above sea-level. It flowers there from December to 
February, and in favoured localities the flower-heads are 
at times two and a half inches across. For the intro- 

April, 1917. 



duction of this fine plant horticulture is indebted to 
Captain A. A. Dorrien Smith, Kineshill, Berkhamsted, 
by whom it was brought to England in 1910, when an 
example was presented by him to Kew. The Kew plant 
has thriven well in a cool greenhouse, but has not yet 
flowered, and for the material from which our illustration 
has been prepared we are indebted to its introducer, 
with whom one of his own examples blossomed for the 
hrst time in July, 1913. As a conservatory plant 
&. Jiectori should prove a welcome acquisition ; at Kew 
it is unfortunately too tender for cultivation out of 
doors.

The Chirita here figured, which was discovered by 
Mr. G. Forrest in May and June, 1912, at elevations of 
from 5,000-7,000 feet in the Shweli Valley and on the 
hills to the south of Tengueh in Yunnan, is one of a group 
of species the hitherto known members of which are 
C. hrevipes, Clarke, a native of the Khasia Hills, and 
C. speciosa, Kurz, which was discovered in south-western 
Yunnan at Poneline by the late Dr. J. Anderson. Yet 
another, but as yet an undescribed species belonging to 
the same group has been found, also in Yunnan, at 4,500 
feet elevation, near Szemao, by Dr. A. Henry. The 
Szemao plant has leaves that are almost exactly like 

Avrii, 1917. 



those of the Tengueh species which its discoverer and 
Mr. W. W. Smith have named C. Trailliana, but the 
calyx-teeth are narrowly linear above the base and the 
blossoms are aggregated in cymes of about four flowers, 
borne on peduncles as short as those of the Khasian 
L.brevipes ; the flowers, however, develop very unequally 
and there is probably, as in C. Trailliana, only one open 
at a given time. Examples of this Szemao plant from 
rather higher elevations have, however, peduncles with 
solitary flowers, and it is not impossible that it may 
eventually prove to be a form of C. Trailliana. The plant 
Irom which our figure was prepared was obtained for 
the Kew collection in 1915 from Messrs. R. Wallace 
and Company, Colchester, by whom it had been raised 
trom seed collected by Mr. Forrest for Mr. J. C. Williams, 
Caerhays Castle, Cornwall. It flowered in June in a 
greenhouse, and is evidently too tender to thrive out 
oi doors m Britain. It survived at Kew after flowering, 
but tailed to mature seeds.

The Saxifrage which forms the subject of our illus- 
tration was first described, as a variety of S. punctata, 
Linn., in 1872 by Engler. The plant on which the original 
account was based had been collected by Wilford on the 
coast of Manchuria in 1857. The Linnean species with 
which Engler thus associated Wilford's plant has a wide 
range in northern Asia, arctic America and the Rocky 
Mountains ; so far, however, as is yet known, Wilford's 
Saxifrage appears to be confined to Manchuria and 
northern Corea, where according to Komarov, who in 
1904 first indicated the desirability of regarding it as a 
distinct species, it is to be found in shady damp places on 
stream-banks. From S. punctata S, manshuriensis differs in 
being a more robust plant with larger and thicker leaves, 
in having the petioles and scapes hirsute, and in having 
the inflorescence globose and contracted. The plant from 

Afeil, 1917. 



which our figure has been prepared was raised at Kew 
from seed obtained from Messrs. Kegel and Kesselring, 
Petrograd, in 1913. The majority of the plants thus 
raised flowered for the first time in 1915. In the Eock 
Garden at Kew S. manshuriensis is in flower from July 
to August. It has proved a hardy perennial, easy to 
cultivate, which flourishes well in moist shady spots.

The genus Corylopsis has its chief centre in China, 
whence it extends to the Eastern Himalaya on the one 
hand, to Japan on the other. The various species are 
charming in gardens for their early blossoming, their soft 
yellow flowers and their gracious perfume. The species 
which forms the subject of our illustration, C. Willmottiae, 
has all these qualities ; it grows freely, and so far it has, 
since it reached this country, given no sign of being at 
all tender. Like other members of the genus, however, 
it is liable to suffer, when in flower, from late spring 
frosts which mar its beauty though they do not affect its 
growth. The introduction of C. Willmottiae horticulture 
owes to Mr. E. H. Wilson, by whom it was first dis- 

April, 1917. 



covered in 1908, south-west of Tachien-lu in Western 
bzecnuan, growing at altitudes of 6,000 to 7,5C0 feet. 
1 wo years later Wilson collected seeds again in the same 
locality, and from these seeds of 1910 most of the plants 
now in cultivation were raised. The plant which has 
provided the material for our plant was purchased for 
Kew from Messrs. J. Veitch and Sons in 1913, and 
flowered there in April, 1914. The species had, however, 
blossomed two years previously in the garden of Miss 
&. A. Willmott at Warley Place, and was exhibited by her 
at a meeting of the Royal Horticultural Society in March, 
1»IJ, as 6. multiflora, Hance, another Chinese species. 
It ripened seeds at Kew in 1916. C. Willmottiae is more 
closely allied to C. Veitchiana, Bean, figured at t. 8349 of 
this work, than it is to C. multiftora, but from our plant 
U Veitchiana may be readily distinguished by its pilose 
calyx and fruits, by its longer nectaries and by its 
exserted red anthers. J

The distinct and handsome Vanda here figured is a 
native of the Philippines. It was collected in central 
Luzon, in the Montalban district, by Mr. A. Loher in May, 
1905, and dried specimens from this locality, accompanied 
by a photograph and drawings, were presented by him to 
the herbarium at Kew in 190b* under the name V. luzonica. 
That living plants had already been introduced to culti- 
vation in Europe is shown by a reference to the fact that 
the species, under this name, was then alive in the orchid 
collection at Erlangen. The plant from which our figure 
has been prepared was purchased for the orchid collection 
at Kew in 1911 from Mr. C. F. Karthaus, Potsdam. But 
although the name V. luzonica was already in use among 
°. r £ hld growers, no description of the species was pub- 
lished until 1915, when a plant flowered in the collection 
of Mr. H. Dixon, Sydney, New South Wales. A little 
later m the same year it was exhibited in flower at the 
Panama Exhibition. In November, 1915, it also flowered 
in the collection of Messrs. Sander and Sons, St. Albans, 

May, 1917. 



and in December, 1915, the Kew plant, too, flowered for 
the first time in a tropical house where it had been 
grown and had thriven well under the conditions suitable 
for V. tricolor ■, Lindl., a species from Java, figured at 
t. 4432 of this work, which is its nearest ally in the 
genus. Though so closely related the two species differ 
very markedly in coloration, the sepals and petals of 
V. luzonica being white, not yellow, with a tinge or, at 
times, a defined spot of purple towards the apex, but 
with no trace of the brown blotches which characterise 
the sepals and petals of V. tricolor. 

Description.— Herb, epiphytic, 10-12 in. high ; stem stout, erect, clothed 
with leafy sheaths. Leaves recurved, oblong, shortly 2-lobed, coriaceous, con- 
duplicate at the base, 6-14 in. long, 1-li in. wide. Scapes erect, about 8 in. 
long, many-flowered; bracts orbicular-ovate, obtuse, spreading, 4-f in. long; 
pedicels 2-2f in. long. Flowers showy, over 2 in. wide. Sepals 5 a nd petals

This interesting and pretty plant, the Bog or Swamp 
Wintergreen of North America, was originally described 
from material collected by Dr. Knieskern at Oriskany, 
Oneida County, New York, where it was found in 
Sphagnum swamps. It is now known to be distributed 
from Nova Scotia to New York, South Dakota, Colorado, 

May, 1917. 



Oregon, and from Washington to Alaska, in bogs, meadows 
and copses. The material figured came in June, 1916, 
from Mr. F. R. S. Balfour, of Dawyck, Peeblesshire, 
where the plant was grown from roots collected by him 
in the Olympic Mountains, Washington. Pyrola uliginosa 
belongs to the section Thelaia, characterised by having 
the petals smooth, not tuberculate, at the base, ascend- 
ing stamens, and a declinate style dilated near the apex 
into a ring or collar, and contracted above into a stigma 
of five erect lobules. The connivent stamens are directed 
towards the upper petals, while the style curves sharply 
away from them towards the lowermost petal, which forms 
a kind of lip. To this section belongs the well-known 
P. rotundifolia, Linn., distinguished from P. uliginosa by 
its more coriaceous shining leaves, larger white flowers 
and much longer calyx-lobes. The variety incarnata, DC, 
of P. rotundifolia (P. incarnata, Fisch.) of Eastern Asia 
has rose-coloured or reddish flowers, and some botanists 
have identified it with P. uliginosa, but it differs in its 
more coriaceous shining leaves and longer calyx-lobes. 
The North American P, asarifolia, Michx., is distinguished 
by its suborbicular-reniform leaves, which are usually 
more or less cordate at the base. The characters 
distinguishing P. uliginosa from P, bracteata, Hook., 
are mentioned in the remarks on that species, a figure 
of which is also given on t. 8710. 

Description.— Herb, perennial, with a long creeping rootstoek; stem very 
short. Leaves nearly orbicular or ovate-elliptic, apex rounded rarely somewhat 
acute, base slightly cuneate and at times unequal, finely crenulate, up to 3 in. 
long, 2| in. wide, thin, quite glabrous, dark green but not polished above, paler 
and sometimes reddish beneath ; petiole up to 4 in. long, sharply 3-angled. 
Scape erect, 6-12 in. high, glabrous, ridged, with 1-3 lanceolate membranous 
scaled i-| in. long. Raceme 2^-4 in. long, laxly 5-20-flowered ; bracts lanceo- 
late, membranous, flushed with rose, about as long as the slender, \-\ in. long 
pedicels. Flowers nodding, fragrant. Calyx 5-lobed ; lobes ovate-triangular 
or ovate-lanceolate, T ' 5 -i in. long, T L i n . wide at the base, acute at the apex. 
Corolla bright red-purple or rose-coloured, especially outside, within usually 
pale rose, about £ in. across ; petals obovate or elliptic, concave, rounded at 
the apex, \-\ in. long, and nearly as wide. Stamens 10, approximated, ascend- 
ing ; anthers purple or rose, their cells shortly mucronate at the base. Ovary 
depressed-globose, 5-lobed, glabrous ; style declinate, about \ in. long, annulate 
at the apex ; stigma 5-lobulate. Fruit depressed-globose, about \ in. across.

The Indian Lettuce or Canker Lettuce of North-west 
America, a figure of which accompanies our illustration 
of Pyrola uliginosa, is also an interesting and pleasing 
plant. The type of P. bracteata, all the flowers of which 
are in bud, was collected by Dr. Scouler on the north- 
west coast of North America ; the precise locality has 
not been recorded. The area it occupies is more 
restricted than that occupied by P. uliginosa ; it extends 
from British Columbia to Idaho and California, in open 
coniferous woods. The material for our illustration was 

Mat, 1917. 



communicated by Mr. F. R. S. Balfour, of Dawyck, who 
lifted the roots in the valley of the Olympic Mountains 
whence came the plant of P. uliginosa figured along with 
P. bracteata. At Dawyck P. bracteata has been grown 
along with P. uliginosa in a Vaccinium bed in a soil of 
peat and leaf mould with sand admixed. The subsoil is 
gravel ; the bed is at the base of a steep bank covered 
with high trees, and is in close proximity to a stream. 
The site is thus well shaded and the atmosphere con- 
stantly moist. There are several points which render the 
discrimination of P. bracteata from P. uliginosa far from 
difficult, notwithstanding the resemblance they bear to 
each other. In P. bracteata the leaves are usually acute and 
the veins end in distinct, though minute marginal teeth. 
The bracts in P. bracteata are larger, the calyx teeth are 
longer and of a different shape ; the petals are longer 
and narrower, and when fully expanded give the flower a 
2-lipped appearance ; moreover, the anthers are yellow, 
not purple or rose as in P. nliginosa. Gray states that, 
at times, the leaves of P. bracteata are variegated with 
whitish bands. The two vernacular names are used, 
according to Parsons and Buck, in California, where a 
preparation possessing astringent properties is made 
from the plant and is used medicinally as a tonic and 
diuretic. 

Description. — Herb, perennial, with a long creeping rootstock ; stem up to 
2 in. in .'height. Leaves nearly orbicular, or ovate or elliptic, apex generally 
acute, base subcordate, rounded or slightly cuneate, minutely and distantly but 
distinctly toothed, up to 3 in. long and 2 in. wide, thin, quite glabrous, dark 
green and shining above, paler and often reddish beneath ; petiole up to 4 in. 
long, sharply 3-angled. Scape erect, 8-12 in. high, glabrous, ridged, with 1-3 
wide-lanceolate, membranous, acuminate scales, j-4 in. long. Raceme 2£-4 in. 
long, 10-25-flowered ; bracts lanceolate, or wide-lanceolate, membranous, 
acuminate, longer than the pedicels, often rose-coloured ; pedicels \-\ in. long. 
Calyx 5-lobed ; lobes lanceolate or triangular-lanceolate, acuminate, about 
l in. long, under j 1 ^ in. wide at the base. Corolla bright red-purple or rose- 
coloured, §-£ in. across; petals elliptic-oblong, rounded or somewhat acute,

The Manchurian genus Plagiospermum, Oliv., is closely 
allied to the Himalayan genus Prinsepia, Royle ; the two 
have by some been regarded as sections of one genus. 
They are, however, very distinct ; in Prinsepia the buds 



May, 1917. 



are perulate, the leaves exstipulate, the stamens in- 
definite with discrete anther-cells, the endocarp thin and 
crustaceous ; in Plagiospermum the budscales are replaced 
by persistent stipules, while the stamens are 2-seriate 
with contiguous anther-cells, and the endocarp is thick 
and stony. The material for our plate was supplied by 
Sir F. W. Moore from a plant of Plagiospermum sinense, 
which flowered at Glasnevin in February, 1916. This 
plant, supplied by Mr. T. Smith, Newry, came originally 
from Messrs. Kegel and Kesselring, Petrograd. In 
March, 1916, another plant flowered at Kew for the 
first time. This plant was presented in 1908 by 
Mr. P. L. de Vilmorin, who had received it from Russia. 
In cultivation three somewhat distinct forms of P. sinense 
are met with. One of these has large leaves with 
relatively large flowers on long pedicels. The other two 
have smaller leaves and flowers ; one of the two has 
fairly long, the other, here figured, has comparatively 
short flower-stalks, whence the name brachypoda. All 
are equally hardy out of doors in this country. 

Description. — Shrub, 6-7 ft. high, virgately branched ; twigs of two kinds, 
the former long, strict, armed with spines, glabrous, clothed with last year's 
grey or whitish smooth bark, the latter rather contracted, bearing clusters of 
leaves ; the spines springing from above the short branches spreading, straight 
or slightly curved, some very short, others over ^ in. long. Leaves usually 
narrowly lanceolate, somewhat acute or obtuse, ani often mucronate, base 
gradually narrowed to the petiole, entire, f-1 in. long, ^-^ in. wide, thin, quite 
glabrous, pale green above, glaucous beneath, nerves obscure ; stipules of the 
leaves on the longer branches lanceolate-subulate, at length indurated, of those 
on the shorter branches thin, filiform, purplish, sometimes sparingly glandular. 
Flower arranged among the leaves of the shorter branches, orange-yellow ; 
pedicels in flower from |-f in. long, or in the form brachypoda now figured only 
To _ s in - long, glabrous. Calyx wide-turbinate, $ in. deep, pale, quite glabrous 
save for the cilia met with on the herbaceous teeth, clothed inside by a some- 
what fleshy disk with an annular opening. Petals orbicular, somewhat denti- 
culate, shortly clawed, ±-\ in. wide. Stamens 10, inserted on the disk-ring ; 
filaments as long as the small anthers. Ovary immersed in the base of the 
receptacle, depressed ellipsoid-globose, quite glabrous ; style lateral or in fruit 
almost basal, slightly exserted from the receptacle, gradually thickened 
upwards ; stigma depressed capitate ; ovules 2, collateral, spreading obliquely 
from the supra-basal placenta ; micropyle almost occluded by a small adaxial 
caruncle. Drupe compressed globose, dark purple, pruinose, \ in. wide ; stone 
elliptic in cross section ; radicle inferior.

The species here figured has been in cultivation in 
English gardens for more than two centuries. It is a 
small evergreen of very neat appearance, and when in 
fruit is singularly ornamental and pleasing. It is, more- 
over, perfectly hardy, and the single plant in the Rock 
Garden at Kew has grown there without any protection for 
the past twenty years. It thrives in either a light loamy 
or peaty soil and may be readily propagated by cuttings. 
In spite of these recommendations it is but rarely 
met with in collections and has been so little regarded 
that no horticultural figure appears to have been pub- 
lished. This is probably due to the fact that the plant 
is strictly dioecious, and that growers who have not been 

May, 1917. 



at pains to procure both sexes have not appreciated how 

attractive the female plant may be when in fruit. The 

plant is inter 3sting as being that on which Linnaeus 

based the genus Myrsine ; it is further interesting in 

having a geographical range much wider than is usual in 

the order Myrsinaceae. The original introduction to this 

country was from the Cape of Good Hope, and samples 

from that region were in cultivation at Hampton Court 

in 1691 ; to Cape specimens also the species owes its 

name M. qfricana. Thence, however, it extends through 

tropical Africa to Afghanistan and Northern India. A 

figure based on a specimen from this region has been 

given in the Flora Simlensis of Sir Henry Collett. It 

occurs again in China whence it has been recently 

re-introduced ; most if not all the plants in modern 

collections are of Chinese origin. The material from 

which our plate was prepared was obtained in May, 1916, 

from the garden at Nymans, Handcross, Sussex, which 

contains one of the finest and most comprehensive 

collections of trees and shrubs in Britain, formed by the 

late Mr. L. Messel, and carefully maintained by his 

daughter. At Nymans two plants of M. qfricana of 

different sexes grow close together ; this has resulted in 

the production of berries, hitherto a very rare event in 

this country. This, however, is not the first occasion 

on which M. africana has fruited in England ; it did so 

at Abbotsbury in 1893 and again in 1898, as specimens 

communicated to Kew in these years testify.

The Horse Chestnut here figured is a native of Japan 
which is less often met with in collections than its merits 
deserve. Where it is grown it is not infrequently con- 
fused with its Chinese congener, Aesculus chinensis, Bunge, 
and in such cases the name may be further erroneously 
transcribed. Even when the fact that it is not the tree 
described by Bunge is appreciated, the practice has 
obtained of terming it A. japonica, a name for which 
there is no authority. The nearest ally of A. turbinata, 

Jcne, 1917. 



the Japanese Horse Chestnut, is the European A. Hippo- 
castanum, Linn., itself ; from that familiar tree it is well 
distinguished by the smaller, obovate, and warted, but 
not spiny capsules, and by the finely and more evenly 
toothed edges of the leaflets. In its foliage A. turbinota 
is the noblest of all the Horse Chestnuts ; young trees at 
Kew carry leaves which, with their stalks, are sometimes 
twenty-seven inches long. One merit of this Japanese 
species is that it flowers somewhat later than the 
common Horse Chestnut. For the material from which 
our plate has been prepared we are indebted to Lieut. -Col. 
Sir George Holford. The tree from which it was gathered 
is growing close to his residence at Westonbirt, and is 
about thirty feet high, with a trunk two feet nine inches 
in girth, and a rounded crown of branches thirty feet 
across. This tree and another larger one at Westonbirt 
we believe to be the largest of their kind in the 
country. They were planted, Sir George informs us, by 
the late Mr. R. S. Holford about thirty-four years ago. 
In autumn the leaves turn clear golden yellow, then 
brown. These trees produce seeds from which young 
plants have been raised. 

Description.— Tree, at its largest 100 ft. high and 20 ft. in girth of trunk ; 
bark of old trees scaling ; winter buds very viscid ; young shoots minutely 
pubescent. Leaves 5-7-foliate, deciduous ; leaflets sessile, 4-15 in. long, 2-6 in. 
wide, the terminal leaflets more than twice the size of the basal pair ; obovate- 
cuneate, shortly acuminate, finely serrate; deep bright green and glabrous 
above, glaucescent and with axil-tufts of pale brown tomentum beneath ; 
petiole 3-16 in. long. Panicles terminal, erect, slenderly pyramidal, up to 
10 In. long by 3£ in. wide at the base ; rachis and pedicels finely pubescent. 
Flowers f in. in diameter, opening in late May. Calyx pubescent, campanulate, 
5-lobed; the lobes rounded, ciliate. Petals 4, subrotund with a narrow claw, 
reflexed, creamy-white with central-blotches of yellow which turn pink with 
age; pubescent above, ciliate. Stamens usually 7, much exserted ; filaments

This fine Stauropsis is remarkable for its exceptional size 
and its ample lax panicle of white flowers with violet blue 
markings on the lip. A native of the Solomon Islands, 
Kew is indebted for the plant to Sir Everard im Thurn, 
who met with it in 1905 when visiting that Archipelago 
on H.M.S. " Torch," as Governor of Fiji and High Com- 
missioner of the Western Pacific. At Langa Langa, on 
the west coast of Mala (Malaita) Island, an opportunity 
was afforded of botanising in the bush. In a forest with 
many large canopy trees but little undergrowth, the plant 
figured was found on a fallen trunk on which grew a 
dense mass of other orchids with ferns and grasses; it 
bore the remains of a fairly recent flower-spike. On 
reaching Fiji it was planted on a topped tree fern under 
a " bush house " in the gardens of Government House. 
It showed no sign of a new flower-spike until May, 1908. 
This spike was under a foot long in August, 1909, when 
it began to develop more rapidly, but still showed no

tendency to branch. In March, 1910, Fiji was ravaged 
by a violent hurricane. The Stauropsis was rescued 
from the "bush house" by Mr. D. Yeoward, Curator 
of the Fiji Botanic Station, and brought intact to 
the ruins of Government House, where it was fastened 
for safety underneath a billiard table. After the storm 
it was reinstalled on its old tree-fern stem, and during 
the next seven months its spike branched to some extent, 
and produced two rather poor flowers. In November, 
1910, it was brought from Fiji by Sir Everard, and after 
a journey across Canada was sent from Liverpool to 
Kew, where it has since thriven well in the Tropical 
Orchid House, coming once more into flower in September, 
1916. During flowering the prolonged development of 
the spike described by Sir Everard as regards 1903-10 
has been equally manifest, but during 1914-16 branching 
has been more extensive. As in 1905 the plant gave 
evidence of having flowered during 1904, it is possible 
that in S. Imthurnii we may have a species which flowers 
only at definite periods. In keeping with this suggestion 
is the fact that in October, 1910, an imperfect dried 
specimen, accompanied by a sketch of a plant of this 
Stauropsis, was received at Kew from Mr. C. M. Woodford, 
then British Resident at Tulagi, Solomon Islands! 
Mr. Woodford found his plant in August, 1910, when the 
flowering period appeared to be nearly over, on the north 
side of Ysabel Island, and has noted that he had met 
with the species once before, but that on the first occasion 
it was not in flower.

The handsome Campanula here figured is a native of 
the province of Aidin in Asia Minor, where it has been 
collected in the neighbourhood of the ruins of Ephesus 
and Priene. Its nearest ally appears to be C. tomentosa, 
Vent., a native of Greece. The Ephesian plant is, how- 
ever, of more robust habit and has larger leaves and 
flowers than the Grecian one ; the corolla in C. Ephesia, 
the subject of our plate, is from twice to thrice as wide 
as that of C. tomentosa, and is much less tubular in form. 
The introduction of this species horticulture owes to 
Sir J. N. Barran, Bart., by whom a living plant was 
brought to England from Priene, where it had been 
found by him in May, 1913. This plant was kept in a 
pot in light soil, mainly sand, with some scraps of lime- 

Jcne, 1917. 



stone on the surface and lightly watered, in a cool house 
at Sawley Hall, Ripon, until the following summer, when 
it was transferred to an open alley roofed with glass. 
Under this treatment the plant throve well, and in 1915 
it was possible to divide it, one of the plants so obtained 
being presented to Kew in February, 1916. From this 
example, which was grown at Kew in a pot of ordinary 
loam, and flowered there in a cool frame in June and 
July, 1916, the figure of C. Ephesia here given was pre- 
pared. A plant at Sawley Hall flowered synchronously 
with the example at Kew. While in flower the Kew 
plant was carefully pollinated, but failed to set any 
seeds ; soon after flowering it died. Sir John Barran 
informs us that the plant which flowered at Sawley Hall 
did the same, but in this case a few seeds were developed 
and saved. There appears to be no record of any 
previous introduction of this species to English gardens ; 
whether its permanent establishment can be effected 
seems as yet doubtful.

Disanthus is an interesting genus of the Hamameli- 
daceae, established in 1866 by Maxim owicz on the 
species now figured. So far as is known at present it is 
monotypic. From the other genera of this natural 
family, Disanthus is well dist nguished by the arrange- 
ment of the flowers, which aie sessile and set, base 
to base, on two-flowered shortly ped uncled capitula. 
D. cercidifolia is described by Sargent as being not rare 
in the Kisogawa valley in Central Hondo, covering steep 
hillsides with thickets sometimes a quarter of an acre in 
extent. It has been in cultivation about twenty years, 
but does not appear to have blossomed often. For the 
flowering twigs now figured we are indebted to Mr. H. W. 
Grigg of Cann House, near Plymouth, where, in a very 
extensive and admirably cultivated collection of choice 
trees and shrubs, a healthy plant about 6 ft. high 
flowered last October. The flowers are of a lurid, un-

attractive hue, and they have a faint, not pleasant 
odour ; but the shrub, as our plate shows, has a real 
value for the rich autumnal tints of its foliage. At Kew 
it has, in this respect, proved one of the most attractive 
of newer shrubs. It likes a sunny spot and a light loamy 
or peaty soil. In the absence of seeds it can be increased 
by layers. The leaves depicted were drawn during the 
last week of October, 1916, and show the autumnal 
colouring. 

Description.— Shrub, 6-10 ft. high, with slender, spreading branches ; twigs 
brown, glabrous, sprinkled with pale lenticels. Leaves deciduous, alternate, 
entire, quite glabrous, broadly ovate to roundish, cordate or truncate at the 
base, blunt or acute at the apex, 5-nerved, 2-4 in. long, nearly to quite as wide ; 
deep green in summer changing to a rich red suffused with orange in autumn ;

The Pine here figured is the Knob-Cone Pine of 
western North America which extends from the valley ot 
the Mackenzie River in Oregon to the southern slopes ot 
the San Bernardino Mountains in California. It occurs 
in somewhat isolated localities, often in fairly lofty and 
exposed situations, where its smaller size and inferior 
appearance have given rise to the alternative name ot 
Scrub Pine. A remarkable feature of the species in all 
its localities is the indefinite persistence of its tightly 
closed cones. Jepson records a limb, five and a half feet 
long, secured by him in the Santa Lucia Mountains, 
California, bearing forty-five cones; in the Museum at 
Kew is preserved a portion of a branch, four feet long, 
from a tree grown at Bayfordbury, which carries more 
than forty cones. The seeds thus imprisoned by the 
scales retain their vitality for many years, and it has 
been said that cones never discharge their seeds until the 
tree, or a least the branch on which they are borne, dies. 
This is not always the case, for after some successive 
days of great heat cones that are four or five years old 
may open and allow their seeds to fall. Ordinarily 
however, the cones remain unopened until subjected to 
the heat resulting from a forest-fire, when the scales 
come apart and the seeds thus liberated afforest the 
devastated area. When first discovered by Hartweg 
in 1847 in the Santa Cruz Mountains, California, the 
Knob-Cone Pine was mistaken for that form of the 
Monterey Pine, P. racliata, D. Don, to which Don had 
given the name P. tuberculoid, and when Gordon drew 
up his account of this tree his description included along 
with it the tree which Don had named P. tuberculata. 
Lemmon, who first set matters right, proposed the name 
P. attentuata for Hartweg's tree ; most authors, however, 
have preferred to accept the transfer of the name 
P. tuberculata to the Knob-Cone Pine. The material for 
our plate was provided by a tree in the Pinetum at Kew, 
one of a pair planted by Sir J. D. Hooker some forty years 
ago ; though quite healthy and perfectly hardy these are 



now only about twenty-five feet high. From what has 
been said above it would appear to be necessary, if seed 
for propagation is to be obtained from cultivated trees, to 
expose the ripe cones for a short time to considerable heat. 

Description. — Tree, usually 20-25 ffe. high, with a trunk 1 ft. in diameter, 
occasionally reaching 80-100 ft. in height and with a trunk twice aa thick ; 
branches somewhat spreading to form a broadly pyramidal crown which 
becomes thinner and flatter with age ; bark at first smooth and brown, with 
age blackish and peeling in broad flakes. Winter-buds cylindric, -|— 1 in. long, 
i in. across, chestnut-brown or purplish, 'resinous ; bud-scales with the 
exception of the lowest closely appressed, lanceolate, subulate-tipped, rather 
deeply and freely fimbriate. Leaves in clusters of threes, encircled at the base 
by hyaline- scar ious sheathing scales which are at first brownish but ultimately 
tawny or grey ; individual leaves acicular, almost pungent, 3-7 in. long, -^ in. 
wide, with very finely serrulate edges, rigid, pale or dull green, convex on the 
back, furrowed when dry between the midrib and margins along the face. 
Male cones cylindric, about f , in. long, £ in. wide, chestnut-brown. Female 
cones aggregated in clusters of 2-4, in flower ovoid- or ellipsoid-globose, 4-f in. 
long. Carpels rounded-ovate, even in flower much shorter than the ovuliferous 
scales, which are wide ovate, thickened upwards and abruptly spinulose at the 
tip. Cones when ripe deflexed and often closely appressed to the branches, in 
outline obliquely elongate-ovate or ovate-oblong, 3-6 in. long, 1-2| in. thick, 
chestnut brown; ripe scales spathulate-cuneate, very close-set, woody, the 
central on the outer face of the cone lf-2 in. long, ^ in. wide near the top, those 
on the inner face of the cone much smaller ; hypophysis rhombic with a fine 
transverse keel ; umbo shortly incurved, spinescent from a broad base. Seeds 
obovoid, i in. long, blackish, broadly winged ; wing oblique at the apex, f-1 in. 
long, i-A in. wide, white or brownish, marked with thicker and finer reddish 
lines.

The handsome Odontoglossum here figured is a native 
of Guatemala, originally described as 0. platycheilum 
from a solitary plant which had flowered in March, 1892, 
in the collection of Mr. R. I. Measures of Camberwell. 
The county of origin of that example was then unknown ; 
all that was known regarding it was that it had been 
acquired along with some other orchids when the 
Downside collection was dispersed. More than a decade 
later a specimen of the same species were received at 
Kew in a collection of dried plants communicated by 
Mr. J. Donnell Smith. This specimen had been gathered 
by Heyde and Lux in April, 1892, at an elevation of 
8,800 feet, at Chiul in the department of Quiche, 
Guatemala; it is now known that a fruiting specimen 
collected by Bernoulli in Guatemala in May, 1860, belongs 
to the same species. In 1905 Messrs. Sander and 
Sons, St. Albans, were able to make an importation of 
this Odontoglossum, which since then has flowered fre-

quently in various collections. The material for our 
figure has been derived from a plant purchased from 
Messrs. Sander, which has thriven well under the con- 
ditions suitable for 0. crispum and has flowered annually 
in May. In the genus, 0. platycheilum is very distinct 
and indeed somewhat aberrant; its nearest ally is 
0. maxillare, Lindl., a species figured at t. 6144 of this 
work. 

Description. — Herb, epiphytic; rootstock almost scandent ; pseudobulbs 
narrowly ovoid-oblong, 2-2f in. long, 1-foliate, clothed below with large sheaths. 
Leaves ligulate, rather blunt, firm, narrowed to the base, 6-11 in. long, \-\\ in.

tvt ^n 8 free ~ flowerin g little Gesnerad was discovered by 
Mr. George Forrest on the eastern flank of the Lichiansr 
Range in North-Western Yunnan. The plant was met 
with on mess-covered boulders and on branches of trees 
in very shady situations at an elevation of from 10,000 to 
11,000 feet. Mr. Forrest sent seeds to Messrs. Bees, Ltd., 
irom whom some were received at Kew in 1913. One of 
the plants raised from these, which flowered in a cold 
house in May, 1915, furnished the material for the accom- 
panying figure. At Edinburgh it has been in cultivation 
since 1909 and there it flowers freely. It is not yet clear 

July, 1917. 



whether the species be hardy at Kew, but it may survive 
a mild winter out of doors if protected from excessive 
moisture. In habit it much resembles Ramondia pyreinaica, 
Rich. Though originally described as a Roettlera, in 
which some authorities merge the genera Didymocarpus 
and Chirita, the structure of the flower indicates its true 
position as a species of the closely allied genus Oreocharis. 
The salient character by which Oreocharis may be 
distinguished from Didymocarpus, Chirita and Didissandra 
is in the four fertile stamens, the anthers of which are 
not coherent or even connivent. Dr. Diels described 
Roettlera Forrestii as having two fertile stamens with 
staminodes, the number of which is not stated. What 
were regarded as staminodes were fertile stamens from 
which the anthers had fallen, the real staminode. a very 
small minute body, being overlooked. Through the 
kindness of Professor Bayley Balfour it has been possible 
to compare and identify the Kew plant with the excellent 
specimens of Roetth ra Forrestii collected by Mr. Forrest 
and now preserved in the Herbarium of the Royal 
Botanic Garden, Edinburgh. The genus Oreocharis now 
includes about tu enty species, all of which, excepting 
0. notha, C. B. Clarke, from the Philippine Islands, and 
O.primulvide*, Benth. & Hook, t, from Japan, are Chinese.

The genus Sinofranchetia is a member of the Lardiza- 
balaceae, a group of forms treated in the Genera 
Plantarum as a distinct tribe of the natural order 
Berberidaceae, but regarded in the Naturlichen Pflanzen- 
familien as a distinct family. The solitary species, 
S. chinensis, is a vigorous climber with inconspicuous 
flowers, but with showy and striking lavender-purple 
fruits, which appears to be common at altitudes of 5,000- 
9,000 feet in western Hupeh and Szechuan. Its botanical 
history has been somewhat confused. In 1889 the late 
Professor Oliver based a new Holboellia, H. cuneata, on 
male and female specimens obtained by Mr. A. Henry in 
Hupeh, pointing out, however, certain differences, besides 
that of sex, in the two components of the species. The 

July, 1917. 



late Mr. Franchet in 1894 described as Parvatia chinmsis 
a species collected by Farges in Szechuan. In this 
Parvatia Professor Diels recognised the female portion of 
Holboellia cuntata, Oliv., so distinct from the male portion 
as to belong to a different subgenus of Holboellia. To 
this subgenus, which Diels had termed Sinofranchetia, 
the rank of a genus was accorded by Dr. Hemsley in 
1909. It has now been discovered that the male portion 
of Holboellia cuneata, Oliv., is also better considered as 
belonging to a distinct genus, a female of which has been 
met with in western Hupeh by Mr. E. H. Wilson. This 
new genus is now known as Sargentodoxa, Render & E. H. 
Wilson, also a member of the Lardizabalaceae. The 
material for our figure of Sinofranchetia chinensis has been 
derived from the collection of Miss E. A. Willmott, 
Warley Place, by whom fruiting sprays were communi- 
cated in November, 1915, specimens with male flowers 
being sent in June, 1916. At Warley Place Sinofranchetia 
was raised from seed in a cold frame, and in the second 
year was planted against a pergola in a north-east 
position. A year later flowers appeared and fruit ripened. 
It has proved perfectly hardy and has been unscathed 
by the severe winter of 1916-17. It is not fastidious as 
regards either soil or position, it calls for no special 
treatment, and may be propagated by seed. 

Description.— Shrub, wide climbing, glabrous in all its parts ; stem twining, 
smooth, at first prumose ; flowering twigs short, closely leafy. Leaves

This handsome Rhododendron was originally met with 
by Lady Wheeler Cuffe, to whom it is dedicated, on 
Sindaung, or " Elephant Hill," a great outlying mass, 
whose summit is 6,000 feet above sea-level, on the edge 
of the Shan plateau in Upper Burma. R. Cuffeanum is 
closely related to R. Dal/wusieae, Hook, f., a species 
which extends from Sikkim through Bhutan to Manipur, 
but differs from that species in having its calyx-lobes 
lepidote outside and fringed with long weak hairs. It 
is more remotely allied to R. Nuttallii, Booth, from 
Bhutan, and to R. crassum, Eranch., from Yunnan, both 
of which have calyx-lobes that are neither lepidote nor 

August, 1917. 



fringed with hairs. Young plants of this and some other 
species from Sindaung were presented by Lady Wheeler 
Cufie in August, 1913, to the Royal Botanic Gardens, 
Glasnevin. From one of these, which flowered in May, 
1915, came the material on which our figure is based. 
Sir Frederick Moore, to whom we are also indebted for 
a photograph from which the sketch of the entire plant

examples the basal swellings are much larger than in 
the one figured. The establishment of the plants proved 
slow, but after twelve months in moist heat in shade it 
was possible* to remove them to a cool orchid house 
where in a deep shade they thrive well A year later 
they were transferred to a cool greenhouse, with a night 
temperature of 45° F., and with ample ventilation. Here 
they have flowered and by their behaviour afford hope 
that they may even be hardy out of doors in the milder 
parts of the United Kingdom. They have been grown 
in ordinary heavy peat, and when once they are well 
established their cultivation offers no difficulty. One of 
the distinguishing features of B. Cuffeanum is its 
fragrance.

The very distinct Berberis here figured is a native of 
Western China. It was originally described by Dr. C. K. 
Schneider as B. aggregata from a flowering specimen 
collected by Potanin in Eastern Kansu with which he 
associated a fruiting specimen gathered by E. H. Wilson 
in Szechuan. It was at first placed by its author in the 
section Sinenses next to B. Wilsonae, Hemsl. Subse- 
quently, however, the opportunity of studying further 
material obtained by Wilson in Szechuan, induced its 
author to transfer B. aggregata, on account of its 
inflorescence, to the section Polyanthae. The material 
for our plate has been obtained from a plant raised at 
Kew in 1911, from seed purchased from the Arnold 
Arboretum which had been collected by Mr. Wilson in 
October, 1910, in the Min Valley, Western Szechuan. As 

August, 1917. 



an addition to outdoor collections B. aggregata possesses 
the merit of being ornamental both when in flower and 
when in fruit, but more especially in the latter condition. 
It is evidently perfectly hardy, thriviDg well in a sunny 
spot planted in a loamy soil ; its abundant seed renders 
its propagation easy. 

Description.— Shrub, 4-5^ ft. high ; young twigs finely puberulous, angular, 
Bjilcate, brown; older branches tawny-grey, faintly angled. Spines 3-fid,

The distinct and attractive Bulbophyllum here figured 
is one that has long been in cultivation. At Kew when 
grown in a teak-basket under tropical conditions it is 
easy to manage and rarely fails to flower freely. It was 
long believed to be a variety of B. Careyanum, Spreng., 
and in many collections has been grown as B. Careyanum 
roseum. It was first recognised as a distinct species in 
1896 by Mr. H. N. Ridley, and was originally described 
by him from material collected by himself on Kedah 
Peak in the Malay Peninsula and by Mr. C. Curtis in 
southern Siam. When naming it B. lilacinum Mr. Ridley 
indicated its affinity to B. Pechei, Bull, a native of 
Moulmein, figured at t. 7286 of this work. These two 
species differ in the colour of their flowers; both are 
equally closely related to B. Careyanum. The date of 

Augcst, 1917. 



its original introduction is uncertain. It seems to have 
been added to the collection of the late Sir Trevor 
Lawrence, Burford, Dorking, in or before 1898 ; in 
November of that year it was submitted by him to Kew 
for identification, with a note that it has been bought 
from the collection of the Hon. Walter Eothschild 
at Tring, but that its native habitat was unknown. 
This plant, which flowers regularly each autumn, was pre- 
sented to the Kew collection by the late Lady Lawrence ; 
our plate was prepared from it when in flower in 
November, 1915.

The Polygonum we figure here was discovered by 
Dr. W. Griffith in 1837 growing on rocks above Sanah, 
in Bhutan, at about 10,000 feet above sea-level. The 
plant remained undescribed until 1886 when Sir J. D. 
Hooker named it P. Griffithii. The species was not 
heard of again until 1904 when it was met with by 
Mr. G. Forrest in moist mountain meadows on the 
eastern flank of the Mekong-Salween Divide in south- 
western Yunnan, at altitudes of 9,000-1 1,000 feet. It 
had already been gathered by Pere Monbeig at Tse-kou 
in the same province, specimens gathered by him reach- 
ing Kew in 1905. Since then Mr. F. K. Ward has also 
collected this species in Yunnan. The material for our 
plate was provided by a plant raised from seeds received at 

August, 11)17. 



Kew in 1914 from Messrs. Bees, Limited, under the unpub- 
lished name P. kermesinum which is now current in some 
collections. At Kew the plants reach a height of 
eighteen inches and flower early in August; though 
quite hardy they have failed so far to mature seeds. 
They form a distinct addition to the Kock Garden, 
striking because of the numerous spikes of rich crimson 
flowers. P. Griffithii approaches most closely P. sphaero- 
stachywn, Meisn., figured at t. 6847 of this work, which 
differs in having usually solitary smaller spikes on longer 
peduncles in the axils of narrower cauline leaves. While 
P. sphaerostachyum has short and often recurved pedicels, 
P. Griffithii has long erect ones. For this reason the 
bracts which are closely imbricate around the central 
axis become visible in P. Griffithii, and by their buff 
colour provide an effective contrast with the rich red of the 
perianth. The leaves of P. Griffithii are in wild specimens 
firm and almost leathery, in cultivated plants usually 
much thinner in texture. 

Description.— Herb, perennial; branches tufted, about 12 from each woody 
stock. Leaves : radical numerous, oblong or elliptic, acute, base rounded or 
acute, almost glaucous beneath, glabrous or at first sparingly hairy, margins 
slightly undulate, nerves sleuder but raised, 4-6 in. long, 1\ in. wide ; petiole

or ovate, 2\ in. long, 1| in. wide; petiole up to 1J in. long; ochrea glabrous, 
brown, 1* in. long. Spikes simple or branched, from the axils of the cauline 
leaves, dense-flowered ; peduncles up to 2 in. long, very slender, jointed near 
the base ; flowers erect. Perianth turbinate, deep rich crimson ; segments 
oblong, obtuse, usually 3-nerved, 1 in. long, -& in. wide. Stamens 8, shorter 
than the perianth ; anthers violet, small, obtuse. Ovary narrow-oblong, 
a-quetrous, ft in. long; styles 3, twice as long as the ovary, bright purple;

This handsome Odontoglossum was originally discovered 
by Warscewicz on the volcano of Chiriqui in Costa Rica, 
at 9,000 feet above sea-level ; it was first described by 
Reichenbaeh, from herbarium specimens, in 1852. Its 
introduction to cultivation did not take place until 
thirty years later when it was imported by Messrs. 
Sander and Sons, St. Albans. The locality was not then 
recorded, nor was it known in July, 1890, when an 
inflorescence was sent to Kew for determination by 
Messrs. E. Vervaet and Company, Ghent. In 1894 
Mr. R. Pfau sent a photograph and a dried specimen 
from San Jose, Costa Rica. It now appears that the 
species also occurs in Colombia ; there is, in the collection 

September, 1917. 



of the late Consul F. C. Lehmann, a dried flower stated 
to be from Yarumal, in the province of Antioquia. The 
material for our figure of 0. chiriquense has been derived 
from a plant acquired for the Kew collection at the Red 
Cross sale held in 1916. Until then this plant had been 
for upwards of twenty years in the collection of Mr. W. G. 
Grove, Holehird, Windermere. At Kew it flowered in 
October. It thrives well in a house suitable for species 
of Miltonia, the Odontoglossum house being too cold in 
winter for this species. It makes vigorous growth in a 
compost of peat fibre and sphagnum and requires a 
liberal supply of water. The nearest ally of 0. chiriquense 
is 0. coronarium, Lindl., figured at t. 7687 of this work, 
of which it has been regarded as a variety, but from 
which it is readily distinguished by its larger and very 
undulate flowers.

The genus Oresitrophe includes only one species, 
0. rupifraga, which was first described by Dr. Bunge in 
1834 from material collected by himself in clefts of rocks 
on the mountains near Lun-zuan-ssi and Ssi-jui-ssi in 
Northern China. It was regarded by him as nearly 
allied to Astilbe, Ham., though in habit very different 
from that genus. In the family Saxifragaceae it is 
certainly somewhat anomalous, though in floral structure 
it agrees best with Chrysosplenium, Linn. ; in habit, 
however, it is as remote from this genus as it is from 
Astilbe. Subsequent to its discovery by Bunge, it was 
again collected on Mount Poa-hua-shan, near Pekin, by 
Dr. Bretschneider ; still later it was collected on the 
western hills near Pekin by Mr. W. Hancock, who has 
noted it as confined to rocky gullies, and as being rare. 
More recently it has been met with again by Mr. F. N. 
Meyer, in crevices of rocks in the Nankow Pass, Chihli, 

September, 1917. 



in northern China, to whom its introduction to horti- 
culture is due. Struck by its suitability as a rockery 
plant, Mr. Meyer sent rootstocks to Kew, as those of a 
species of Saxifraga, in 1913. Since their arrival these 
plants have been kept in pots in a cold frame. They 
have thriven satisfactorily and flowered freely both in 
1915 and 1916, when our drawing was prepared. Though 
it has not yet been planted out, 0. rupifraga promises 
to be quite hardy at Kew. The leaves, in autumn, turn 
brown-purple. 

Description.— Herb, stemless ; rootstock thick, scaly, growing in clefts of 
rocks. Leaves 2-3, radical, petioled, wide cordate, abruptly shortly acuminate, 
sharply double-serrate, glabrous above, villous beneath, l*-3 in. long, l£-2f in.

The charming Rhododendron here figured appears to be 
confined to the Tali range in Yunnan where it was 
originally discovered by the Abbe Delavay a generation 
ago. It has been repeatedly met with on the same range 
by Mr. G. Forrest, at altitudes of 9,000-11,000 feet. 
Plants have been raised by Mr. J. C. Williams, Caerhays 
Castle, Gorran, Cornwall, from seed collected by Mr. 
Forrest, and from one of these came the material for 
our plate. Mr. Williams informs us that JR. neriiflorum, 
which has now been in his collection some six years, 

September, 1917. 



grows both well at Caerhays and at Werrington, near 
Launceston, which is colder than Caerhays. It is a 
dwarf shrub which begins to flower when less than 
eighteen inches in height ; even in the wild state it does 
not exceed five feet in height. According to Forrest the 
flowers vary in shade from deep rose to crimson scarlet 
and as grown in this country it provides brilliant patches 
of colour. It has proved easy to grow and has the 
advantage of thriving well in more open spaces than the 
Indian species whose flowers are of the same rich colour. 
ft. neriiflorum belongs to a group of species in the section 
Eurhododendron characterised by their smooth eglandular 
leaves. Among these it is readily distinguished by the 
pinkish glaucous, finely reticulate under surface of the 
leaves, the crimson calyx, and the glabrous filaments. 
It does not appear to be closely related to any other 
Chinese species, and is only remotely allied to the Sikkim 
fi. Thomsoni, Hook, f., figured at t. 4997 of this work. 
In E. Thomsoni the corolla is of the same colour, and the 
under surface of the leaves has the same glaucous bloom, 
but the leaves in the Sikkim plant are cordate at the 
base and more orbicular in outline, while the ovary is 
quite smooth, not hairy as in B. neriiflorum. 

Description.— Shrub, loosely branched, up to 5 ft. high ; twigs purplish, 
glabrous, nearly cylindric, about i in. thick in their second season. Leaves 
scattered, long stalked, oblong, rounded and bluntly apiculate at the tip, base 
truncate or occasionally shortly cuneate, 3-4 in. long, 1-lf in. wide, firmly 
coriaceous, bright-green above, glaucous-green beneath, glabrous ; midrib slightly 
sun* above raised beneath and then near the base rounded and about T V in. 
wide ; lateral nerves about 12 on each side of the midrib, slender, flexuous, 
becoming indistmct near the leaf margin ; reticulation fine and rather visible 
beneath ; petiole red-purple, J-f in. long, at first finely scurfy-puberulous, soon 
glabrous. Flowers in a nearly terminal, rather racemose, usually 8-flowered

Aster fusceseens is a species originally discovered in 1889 
by the late Abbe Delavay, in the Tsang-chang mountains, 
Yunnan. It was met with again in 1890 near Ta-chien-lu, 
in Szechuan, by Prince Henri d'Orleans and Mr. Bonvalot' 
and was first described from their specimens. The 
species bears considerable resemblance to the well-known 
A. scaler, Thunb., which also occurs in Yunnan and 
Szechuan, but extends thence northwards as far as Corea 
and Japan. From that species A. fusceseens differs in 
its more rounded leaves, its less winged petiole, and 
particularly in the linear-lanceolate, acutely acuminate, 
glandular-puberulous bracts of the involucre ; the flower- 

September, 1917. 



heads of A. fuscescens are moreover distinctly larger than 
these of A. scaler. The plant figured was grown from 
seed presented to Kew in 1914 by Messrs. Bees. These 
seeds had been collected in western China by Mr. F. K. 
Ward. A hardy perennial which grows vigorously and 
ripens its seeds freely in a herbaceous border, A. fuscescens 
is well worth cultivating. At Kew it reaches a height 
of about two feet.

This pleasing Pleione is a native of Formosa, where it 
was discovered by Mr. W. R. Price, during the joint 
expedition to that island by Mr. H. J. Elwes and himself. 
In 1914 pseudobulbs were sent by Mr. Price to Kew, 
where they produced flowers in the following spring. It 
was at first believed that the species might prove to be 
P. formosana, Hayata, a native of the same island first 
described in 1911, of which there is no specimen available 
for comparison. The description of P. formosana, how- 
ever, indicates that in that species the stems are ten 
inches high with racemes of two to three flowers, bracts 
over an inch and a half in length and a 4-lamellate in 
place of the 2-lamellate lip-disk met with in P. Pricei. 
The figure now given has been prepared from the plants 
received at Kew from Mr. Price, but it has to be noted 
that another plant, which flowered in the collection of 
Mr. Elwes at Colesbornein April, 1917, produced a flower 

October, 1917. 



of a rather darker rosy-lilac shade with the bract more 
distinctly lined with red. The species has thriven well 
in a tropical house under the conditions and treatment 
suitable for the Indian P. Ilookeriana, which it resembles, 
figured at t. 6388 of this work as a Coelogyne.

The genus Castilleja is composed of herbs or under- 
shrubs which appear to be parasitic on the roots of other 
plants and are for this reason, as is the case with many 

October, 1917. 



Scrophulariaeeae of the tribes Gerardieae and Euphrasieae f 
impossible or difficult to cultivate. Upwards of 150 
species have been described, but many are of doubtful 
validity, and their number would probably be consider- 
ably reduced were the genus carefully revised. Mostly 
natives of Western North America, several are found in 
Central America, a few in the Andes of South America 
and one in Brazil and other parts of Tropical South 
America. One species, C. pallida, Kunth, extends from 
North-West America to Northern Asia, Arctic Russia 
and Lapland. C. miniata, popularly known as Bright 
Painted-cup, has a wide distribution in Western North 
America, ranging from Alaska southward along the 
higher mountains to California. Tt was originally 
described from specimens collected in 1826 by Douglas 
in the Blue Mountains of Northern Oregon and from 
others collected by Tolmie. The material figured was 
sent to Kew by Mr. H. J. Elwes of Colesborne, Chelten- 
ham, and this was furnished by a plant which he received 
from Mr. F. R. S. Balfour of Dawyck, Peeblesshire, who 
sent it home with others during his visit to North- West 
America in 1913. The plants were lifted near Lake 
Agnes in the Canadian Rocky Mountains at about 8,000 
feet elevation. Mr. Balfour was uncertain whether the 
species should be called C. purpurascens, Greenman, or 
6. miniata, but was inclined to think that it should be 
the latter, as it grows above timber line and is cardinal 
scarlet, occasionally pinkish and rarely whitish, whereas 
the former is more usual at lower altitudes and is gener- 
ally of a purplish hue. Q. purpurascens is not represented 
in the Kew Herbarium. Judging from the description 
there is nothing to distinguish it from C. miniata except 
the purplish colour. According to Grav's treatment of 
LastiUeja m his Synoptical Flora the plant now figured 
should not be C. miniata, in which, he has stated, the 
calyx is about equally cleft before and behind, and the 
upper hp (galea) of the corolla is longer than the tube, 
lhe plant described here has the calyx more deeply 
cleft in front, and the upper lip of the corolla is distinctly 
longer than the tube. In these characters the subject 
of our figure agrees with the original types. C. miniata is 
by no means a new introduction into English gardens. 



It is stated that it was first grown in this country in 
1874. There is a plant in the Rock Garden at Kew 
which was received some years ago from the nursery of 
Sir J. Gore Booth, Lissadell, Sligo. This has thriven 
well in a partially shaded position in ordinary soil, and 
has proved quite hardy. It flowers annually in June 
and is easily propagated by seeds. The species has also 
flowered in the garden of Mrs. Longstaff at Wimbledon 
and in that of Mr. Balfour at Davvyck. When viewed 
in great numbers and amid natural surroundings it is an 
unusually striking plant, "For mass of colour," writes 
Mr. Balfour regarding C. miniata and allied species, " I 
never saw anything equal to them except perhaps a 
British poppy field." Several species of the genus have 
appeared in gardens from time to time ; one of these, 
C. vndivisa, Engelm., from Texas, is figured at t. 6376 of 
this work.

The genus Orthrosanthus, "morning flower," includes 
seven species, five of which are confined to West 
Australia; a sixth species is said to occur in South 
Brazil ; the seventh, which is here figured, has a wider 
range than any of the others, for it extends along the 
Andes from southern Mexico to Peru and Bolivia. The 
nearest ally of Orthrosanthus is Sisyrhichium, Linn., from 
which our genus differs in having free filaments. But 
the Brazilian species 0. spicatus, Baker, is said to have 
the filaments united, and on this account it has been 
referred, in the " Flora Brasiliensis," to Sisyrinchiwn. If 
this treatment be accurate, then 0. chimboracensis, the

species now figured, is the only member of the genus in 
South America. Though this species was originally 
described many years ago, it does not appear to have 
been introduced to cultivation until 1876, when it 
flowered in the collection of Mr. Tyerman. The material 
ior our plate was supplied by Mr. H. J. Elwes, with whom 
it flowered at Colesborne, Cheltenham, in 1916. Mr. 
Elwes informs us that the record of the original source 
ol his plant has been lost. In his collection it grows 
well in a cold greenhouse, and sets seeds freely.

The Daphne here figured was first met with by Pere 
Giraldi, after whom it is named, in 1894 on Mt. Tue-lian- 
pu in Northern Shensi. It was collected by him again 
in 1897 in other localities in the Tsin-ling range, and in 
1899 it was found by Mr. H. Scallan on Mt. llgosan in 
the same province. Some years later it was found in 
Western Kansu, at elevations of about 9,000 feet, on the 
mountains to the west of the Tow River by Mr. W. 
Purdom when collecting on behalf of Messrs. J. Veiteh 
and Sons, by whom it was introduced to cultivation. 
The material for our plate of D. Giraldii has been 
supplied by Mr. G. W. E. Loder from a plant in his 
garden at Wakehurst Place, Ardingly, Sussex. This 
plant, which was obtained from Messrs. Veiteh in 1913, 
has been grown since then in an open border, where 
it has proved quite hardy and has developed into a bush 
two and a half feet high with a crown four feet in 
circumference. It has flowered fairly freely at Wake- 
hurst Place, but does not set seed very readily. Mr. 

October, 1917. 



Loder informs us that he has been able to layer the 
plant and has succeeded in striking a few cuttings. 
D. tangutica, Maxim., the species with which it has been 
confused, differs in having persistent leaves and bracteate 
inflorescences. The remaining species of the section 
Alpinae have white, silky flowers, and all occupy areas 
which lie to the north and west of that in which 
J). Giraldii occurs.

The Cherry here figured was originally introduced to 
the United Kingdom by Mr. T. Smith of Newry, and 
distributed by him as Prunus Miqueliana, the name under 
which he had received it from Japan. The plant from 
which the material for our plate was gathered is one in 
the Kew collection which was purchased from Mr. Smith 
in 1912. It flowered in December of that year, and on 
being compared with an authentic example of P. Mique- 
liana was found to diner from that species. It was then 
sent to Professor Koehne of Berlin, who expressed the 
view that it was a variety of his P, microlepis. The 
material at his disposal was, however, very incomplete, 

October, 1917. 



and since then this and other Japanese cherries have 
been very carefully studied in the living state in their 
native country by Mr. E. H. Wilson, who has definitely 
concluded that the subject of our illustration is the 
autumn-flowering variety of P. subhirtella, Miq., figured 
at t. 7508 of this work. The confusion as to the identity 
of this tree is shown by the involved nomenclature 
quoted by Mr. Bean. This confusion appears to have 
resulted from the variable shape of the receptacle which 
while usually funnel-shaped or tubular may be campanu- 
late or even tumid below the middle. This variability 
is largely dependent on the degree of " doubleness " in 
the flower. Coming into blossom as it does in October 
and bearing delightfully fragrant flowers which continue 
to appear until December, this tree forms a charming 
accession to our flora. The figure given was prepared 
m October, 1916, while the tree was still in leaf, and was 
then as gay as any spring-flowering cherry. At Kew it 
does not flower so freely during the two latter months 
when the leaves have fallen ; this, however, is perhaps 
only because weather conditions are then usually more 
inclement. According to Wilson this variety in Japan 
does sometimes, like the typical P. subhirtella, produce 
flowers in April, although even then it does so sparingly ; 
at Hew it has not, so far, produced any flowers in spring.

The genus Megacarpaea is widely spread in Asia from the 
Caspian Sea to Western China, and from the Altai range 
to the Western Himalaya. It includes some seven 
species, one of which, M. bifida, Benth., confined to 
Kashmir, and a second, M: polyandra, Benth., now figured, 
occurring both in Kashmir and Kamaon, deviate remark- 
ably in the number and disposition of their stamens from 
the arrangement characteristic of the natural family 
Cruciferae to which the genus belongs. The presence of 
the genus in the Himalaya was first ascertained by 
Dr. H. Falconer, who obtained flowering specimens of 
Jf. polyandra in Kashmir in 1838. Specimens, in leaf 

November, 1917. 



only, were obtained by Mr. J. E. Winterbottom in the 
same province in 1847. In 1848 it was gathered for the 
first time in Kamaon, in flower, by (Captain afterwards 
General Sir) R. Strachey ; and in 1849 it was met with 
also in Kamaon by Colonel E. Madden in flower in 
May and June, in fruit during September and October. 
Since then it has been met with in Kashmir by Dr. J. E. 
T. Aitchison, and in both provinces by Mr. J. F. Duthie 
who gathered it, in flower, in Kamaon in 1886, and, in 
fruit, in Kashmir in 1892. For the introduction of the 
species to this country, horticulture is indebted to Colonel 
Madden, by whom seeds were sent to Glasnevin in 1849. 
The plant raised there by Mr. D. Moore throve well and 
grew to a great size, but did not flower until 1855. 
Plants raised from seed subsequently introduced flowered 
in 1889 in the garden of Sir J. D. Hooker at the Camp, 
Sunningdale, and in 1892, under the care of Mr. F. 
Burbidge, in that of Trinity College, Dublin. At Kew 
and at Cambridge, on the other hand, where plants were 
grown for many years, M. poly and >a never produced 
flowers. The same was the case with two other plants, 
received from Kew, which grew for many years in the 
garden of the late Canon Ellacombe, at Bitton. In 
1908 the Bitton plants were transferred to the garden of 
Mr. G. H. Wollaston, Flaxley Cottage, Flax Bourton, 
where at last one of them flowered in 1916. The material 
for our illustration was kindly supplied by Mr. Wollaston 
from this plant, which has thriven quite well in a 
herbaceous border in ordinary soil and with no special 
treatment. After flowering the plant died down, but 
recovered itself in the following spring. The nearest 
ally of M. polyandra is M. bifida. But while the two 
share the peculiarity of possessing more than six stamens 
they are readily distinguished by their leaves, the 
segments of which are toothed in M. polyandra, quite 
entire in M. bifida; and by their fruits, usually unequally 
lobed and never deeply divided in M. polyandra, almost 
always equally lobed and always very deeply divided in 
M. bifida. They share further the peculiarity of shy and 
erratic flowering ; in the case of M. bifida, indeed, which 
has long been in cultivation at Kew, there is no record 
as yet of its having flowered in this country. In the 



Himalaya M. polyandra occurs on the open downs above 
the tree-limit at elevations of 10,000-13,000 feet; as 
late as 1872 it was believed that M. bifida, which has been 
gathered at elevations of under 8,000 feet, was confined 
to a lower zone. This is now known not to be the case ; 
M. bifida was collected by Dr. Giles, in 1885, at 12,000 
feet above sea-level in Kashmir. The roots of M. poly- 
andra, which is known to the mountaineers of Kamaon 
as the Rugi, are pounded and eaten as a condiment ; in 
Kashmir the leaves are used as a vegetable. 

Description. — Herb, perennial ; root 4-5 in. thick at the crown, giving off 
several stout stems which, when in flower, are 6-8 ft. high. Leaves pinnati- 
sect ; basal 2£ ft. long, segments about 8-9 on each side, lanceolate, 
acuminate, serrate- dentate or denticulate, sparingly softly pubescent or nearly 
glabrous beneath ; cauline similar but smaller, with fewer segments or the 
uppermost entire and linear-lanceolate. Inflorescence very large, panicled, the 
rachis, branches and pedicels more or less finely hairy ; pedicels up to § in. long. 
Sepals wide-elliptic, quite obtuse, \ in. long, membranous, white. Petals 
obovate, as large as the sepals, crenulate, yellowish-white. Glands at the base 
of the filaments as many as the stamens, green. Stamens 8-15, filaments 
rather stout, almost as long as the petals ; anthers small. Ovary compressed 
laterally, almost orbicular in outline ; stigma capitate, nearly sessile. Siliqua 
when young orbicular, emarginate, soon distinctly but usually unequally 
2-lobed ; lobes winged, when ripe tawny, often with one small dull-green lobe 
and with the other orbicular, 1 in. across, including the J in. wide wing. Seed 
solitary, elliptic in outline, flattened, f in. long ; radicle accumbent.

The charming Primula here described and figured is a 
denizen of woodlands at higli altitudes in Yunnan, where 
it was originally discovered by the late Abbe Delavay, 
by whom it was named P. nutans. Its introduction to 
our gardens we owe to Mr. G. Forrest, by whom seeds 
were obtained and transmitted to Mr. J. C. Williams, 
Caerhays Castle, Cornwall. The plant figured was raised 
from seed presented to Kew by Mr. Williams in 1915. 
The species is a member of the section distinguished by 
Professor Bayley Balfour as Soldanelloides, and is not 
easily distinguished from another described later by 
Mr. Franchet as P. penduliflora, of which our material is 
not altogether adequate. The two appear to differ as 

November, 1917. 



regards foliage, the leaves of P. pendulijlora being only 
simply dentate with the teeth more distant. The section 
includes several beautiful Himalayan species, most of 
which are in cultivation, and all of which have rather 
few nodding or reflexed sessile flowers arranged in more 
or less globose heads. Among these may be mentioned 
P. Reidii, Duthie, figured in this work at t. 6961, and 
P. Wattii, King, figured at t. 8456. The representative 
species of the section is taken by Professor Balfour to be 
P. spicata, Franch. At Kew P. nutans has grown well 
and flowered freely in the Rock Garden and also in pots 
in a cold frame. It is evidently quite hardy. It pro- 
duces good seeds, but perishes after flowering. 

Description. — Herb, in cultivation monocarpic, up to 1 ft. high ; base some- 
what fibrous. Leaves petioled, elliptic -oblanceolate, quite obtuse or rounded 
at the tip, gradually narrowed downwards with a broad winged petiole, 
2^-6 in. long, 1J-1£ in. wide, doubly repand - toothed, thinly papery or 
membranous, shortly softly hairy on both surfaces ; lateral nerves 8-10 along 
each side of the midrib, which they leave at an angle of 45°, raised on both 
surfaces; petiole li-lj in. long, with broad membranous wings. Flowers 
6-10, nodding, sessile, crowded in a long-stalked head ; scape white-mealy 
towards the top, twice as long as the leaves. Calyx wide-campanulate ; tube 
\ in. long, green, white-mealy outside, lobes wide-ovate, acute, J* in. long,

The charming Rhododendron here figured is a native of 
China, where it is common in the mountains of Eastern 
Szechuan and Western Hupeh. It was originally 
discovered near Tchen-keou-tin, in the former province, 
by Farges, in whose honour it was named /?. Fdrgtsii 
by Franchet in 1895. It was met with again in the latter 
province by Mr. E. H. Wilson, in 1901, when collecting 
on behalf of Messrs. Veitch. In Western Hupeh, Wilson 
found it to be abundant in the upper woodlands, never 
occurring at elevations below 6,000 feet. The species 
was raised in their Coo m be Wood nursery by Messrs. 
Veitch from seed supplied by Wilson, and the material 
for our plate has been obtained from a plant purchased 

November, 1917. 



for Kew from Messrs. Veitch in 1913. At Kew it is not 
a very leafy or free-growing shrub, and although it is 
apparently hardy enough to withstand frosts as severe 
as those experienced during the winter of 1916-17, it 
thrives much better in the south-western counties. 
Blossoming as it does in April, its flowers are liable to 
damage by late frosts, a disadvantage which it shares 
with many other Chinese species of the genus. "When 
seen at its best B. Fargesii is very pleasing in the soft 
colouring of its blossoms which, according to Wilson, 
vary m their native woods from deep rosy red to nearly 
or quite white. Its nearest ally is R. erubescens, Hutchin- 
son figured at t. 8463 of this work, but it is readily 
distinguished from that species by its perfectly glabrous 
filaments The nearest Himalayan species is R. campylo- 
carpum Hook, i, a denizen of high altitudes in Sikkim, 
figured at t. 4968 of this work, which differs in having 
yellow flowers and slightly pulverulent leaves.

The interesting Sarcochilus here figured was originally 
described from herbarium material accompanied by a 
photograph of an entire plant communicated to Kew by 
Mr CM Woodford from Tulagi, in the Solomon Islands, 
in which archipelago he reported the species to be 
common. Subsequently a living plant was brought 
from the archipelago to England by Sir Eyerard im 
Thurn, and presented to Kew in September, 1910. Here 
it has been grown in a tropical house, in company with 
various members of the genus Phalaenopsis, to some of 
which our plant, when out of bloom, bears a considerable 
resemblance. Like these it thrives remarkably well 
under conditions of great heat and moisture, with dense 
shade during bright weather. Under these conditions it 
flowered in June, 1916, when the figure here supplied 
was prepared. Though so like a PMaerwpns m habit, 
the plant differs greatly in its inflorescence and floral

the genus barcochilm are singularly fugacious, but after a

The interesting Cucurbitaceous plant, Sechium edule, 
which forms the subject of our illustration, is known 
from Mexico southwards to Panama as the Chayote, a-

name modified in the West Indies to Chocho. One of 
the cultivated plants of American origin unknown in a 
wild state, we owe the earliest European account of it to 
Hernandez, who in the sixteenth century found it used 
as a vegetable in Mexico. It is not mentioned by Sloane 
as a crop in Jamaica at the close of the seventeenth 
century. From P. Browne, however, we learn of its 
presence and of the use both of its fruits and its root in 
Jamaica by the middle of the eighteenth century, while 
according to Grisebach it had, by the middle of the 
nineteenth century, become naturalised there in thickets. 
Its cultivation has nOw extended to Louisiana, to some 
of the Atlantic and of the Pacific Islands, to Southern 
Europe and Northern Africa, to the East Indies and to 
Australia. In its new homes it is known, according to 
its source, now by its West Indian, now by the Mexican 
name. In suitable climates the Chayote is not difficult 
to grow. It is not fastidious as to soil, but requires 
shelter, as it is susceptible to injury from wind, and must 
be provided with support because, in the Tropics, it 
thrives poorly if left to trail on the ground. The 
perennial root, which resembles a Yam, enables it to be 
cultivated in regions liable to frosts, provided these are 
not so severe as to affect the soil. Where the ground is 
frozen in winter, however, it needs greenhouse conditions, 
and in this country is only to be met with in conserva- 
tories capable of supplying sufficient room for its develop- 
ment. Under such circumstances its vigorous growth 
and its ornamental leaves render it a striking object. 
For the material for our figure we are indebted to 
Mr. R. I. Lynch, by whom it has been supplied from a 
plant which flowered and fruited at the Cambridge 
Botanic Garden in 1916. Like many other economic 
species, the Chayote exhibits a considerable degree of 
variation in shape of leaf, length and density of raceme, 
indumentum and length of neck of ovary, as well as in 
form, colour and armature of fruit. It is not at present 
possible to estimate the significance or taxonomic value 
of this variability. The germination of the solitary 
seed presents some features of interest. At maturity the 
seed is enclosed in the fruit, but prior to germination it 
grows so that the tips of the cotyledons extend further 



towards the base of the fruit while the hypocotyl emerges 
from the apex and emits several rootlets. As these 
rootlets find their way into the soil the stem arises from 
between the cotyledons ; the enlargement of the root 
does not take place until the second year. In Mexico 
advantage is taken of this peculiarity, and the seed is 
allowed to germinate before the fruit is planted.

thick ; branches sulcate, smooth, glabrous. Leaves membranous, up to 
10 in. across, rounded cordate, sinus sometimes broad, at others deep and

Syringa Wilsonii is undoubtedly a very close ally of 
S. tomentella, Bureau & Franchet, and it is difficult to 
point to any character of essential importance to distin- 
guish them except the markedly pubescent character of 
the latter. Both leaf surfaces in S. tomentella are pube- 
scent, the lower one almost velvety; the main and 
secondary axes of the panicle, as well as the pedicels 
and calyx, are also pubescent. We have not seen the 
fruit of S. tomentella, but that of S. Wilsonii at Kew 
is perfectly glabrous. Mr. E. H. Wilson discovered this 
lilac on the mountains near Tachien-lu in Western 
Szechuan, China, when collecting for Harvard University 
in 1908. S. tomentella was collected by Mr. A. E. Pratt 
in the same district about twenty years earlier and at 
about the same elevations, viz. 8,000-10,500 feet. The 
plant from which the material for our plate was gathered 

December, 1917. 



was presented to Kew in 1910 by Professor Sargent. It 
has flowered for several years past, usually about the 
beginning of June. At that season it makes a charming 
picture, all the more so because it comes into bloom 
after the flowers of the race of common lilacs have faded. 
It likes a loamy moist soil, and may be propagated by 
cuttings or seeds.

The remarkable Orchid here figured is believed to have 
first appeared in cultivation in the collection of Mr. 
Linden. At a sale of his plants an example was acquired 
by the late Mr. J. Day of Tottenham as an undescribed 
Restrepia, believed to be a native of New Granada. This 
plant flowered in Mr. Day's collection in July, 1875, 
and five years later it was described for the first time 
by Professor Reichenbach as Masdevallia Dayana. The 
generic position then assigned to our plant was in 
keeping with that accorded to a near ally from Jamaica 
originally described by Professor Lindley as Specklinia 
atropurpurea, but later redescribed by the same author 
as Masdevallia fenestrata, Lindl. This Jamaican species 
has been figured at t. 4164 of this work where Sir William 
Hooker, who termed it the " Windowed Masdevallia," has 

DSCSKBBK, 1917. 



given a full and clear account of the peculiar appearance 
which its flowers assume. The singular arrangement was 
again very carefully described and discussed by Mr. 
Darwin in 1862, though in this instance that author was 
under the necessity of concluding that " some new and 
curious contrivance has here to be made out," and the 
riddle as to how in this case insects perform the act of 
fertilisation still remains unsolved. The original belief 
that the species here described was a native of Colombia 
was in time confirmed by the receipt of examples sent 
from that country by Mr. G. Wallis to Messrs. James 
Veitch and Sons. The generic position which Reichen- 
bach and Lindley had assigned to this plant and its 
Jamaican congener was felt to be very unsatisfactory, 
and in 1887 the "Window-bearing Orchids," of which 
there were at least eight, were made the subject of 
careful study by Mr. R. A. Rolfe, who then showed that 
both the Jamaican and Colombian species belong to the 
genus Cryptophoranthus, established by Mr. Barbosa- 
Rodriguez, now known to include fourteen described 
species, among which they stand as Cryptophoranthus 
atropurpureus and C. Dayanus respectively. The culti- 
vation of C. Dayanus does not offer any especial difficulty; 
it thrives well in a tropical house under the conditions 
suitable for species of Masderallia. The species is now 
not uncommon in collections ; the plant here figured 
flowered in the Kew collection in October, 1916. 

Description.— Herb epiphytic, about 10 in. high ; stems clustered, cylindric, 
rather slender, clothed with oblong somewhat imbricate spathaceous sheaths, 
1-foliate. Leaves subsessile, wide-elliptic or orbicular-elliptic, rather obtuse, 
coriaceous, 2J-3* in. long, l|-2* in. wide. Flowers axillary, solitary or few, 
large, straw-coloured with brown blotches ; bracts ovate, apiculate, 4-4 in. long j 
pedicels 3- 3 m. long. Sepals elliptio-oblong, free in the middle but connate at 
base and apex so as to form a tube, laterally fenestrate, recurved and apiculate

The Grevillea here described, G. oleoides, is a native of 
New South Wales, where it is a common shrub in sandy 
places in the bush. The plant from which material for 
our figure was obtained was raised at Kew from seeds 
purchased in 1910 from Messrs. J. Staer and Company, 
Wahroonga, New South Wales. It grows well and 
flowers readily in an ordinary greenhouse under the 
treatment suitable for the nearly allied G. punieea, R. Br., 
figured at t. 6(598 of this work, and like that species is a 
desirable decorative conservatory plant. The charac- 
teristic arrangement of the leaves, in groups of three near 
the bases of the leafy stems, higher up in pairs, near 
the apex solitary, is due to the production of abbreviated 
axillary lateral shoots. In wild specimens the leaves of 
G. oleoides exhibit considerable variation in size, from 
long and rigidly linear with strongly revolute margins to

broadly linear or oblanceolate. The forms with broad 
leaves approach very closely indeed to G. punicea, and 
when the plant is not in flower the only obvious differ- 
ence lies in the greater length of the leaves in G. oleoides. 
In flower the two species are more readily separated, 
the inflorescence of G. oleoides being nearly sessile. 

Description.— Shrub, erect ; twigs clothed with appressed silky hairs, leafy 
towards the top. Leaves linear, gradually narrowed to the base, apex 
sharply apiculate, 2£-3£ in. long, $-| in. wide, green above, finely punctate, 
silvery silky-tomentose beneath ; uppermost leaves solitary, those lower down 
the twig in groups of 2-3. Racemes congested at the tips of short lateral 
twigs, almost sessile, about 12-flowered ; pedicels \ in. long, silky-pubescent. 
Perianth bright carmine, thinly silky outside, densely bearded towards the top 
within, tube £ in. long, revolute below the oblique limb. Anthers short, sub- 
sessile. Qland semi-annular, thick, fleshy. Ovary stipitate, glabrous; style 
far exserted, l\ in. long, gradually thickened towards the apex, crowned by 
the oblique flat orbicular stigma.
