—J. HUTCHINSON.

The Senecio here figured is a native of Japan and of
Northern China, and is a member of the section Ligularia,
whose forms are difficult to discriminate in the herbarium.
Mr. Franchet considered our plant a form of S. Ligularia,
Hook. f., for which he used the name S. cacaliaefolius,
Sch.-Bip.; Mr. Maximowicz, on the other hand, accorded it
separate recognition. In 1887 Mr. Hemsley, a third great
authority on the Chinese flora, was inclined to adopt (Ind.
FI. Sin. vol. i, p. 455) the view of Franchet; in 1905, when

Januaky, 1913.

living plants were available for study, he was able to vindi-
cate the conclusion of Maximowicz. As Mr. Hutchinson
now points out, S. stenocephalus may be readily distinguished
from S. Ligularia by the long and narrow bracts which sub-
tend the peduncle and -by the narrower fewer-flowered heads.
The material for our figure was received from Messrs.
J. Veitch and Sons, and was derived from a plant obtained
in Northern China by Mr. W. Purdom. It promises to be
hardy, and to be an acceptable addition to the wild garden.

The handsome Rose here figured is one grown from
Chinese seeds obtained by Mr. E. H. Wilson on behalf of
Messrs. J. Veitch and Sons, which flowered in the Kew collec-
tion in June 1910. The flowers show that it is identical
with another plant collected by Mr. A. Henry, which the
late Professor Crepin thought might be a small-leaved form
of £. macrophylla, Lindl., and with two other Chinese plants
presented by Messrs. Vilmorin, Andrieux, as 2. Webbiana,
Wall. Neither of the suggestions hitherto offered is, how-
ever, wholly satisfactory. From &. macrophylla the species
here described as A. sertata differs in its much smaller
rounded leaflets and in numerous other details ; from
Le. Webbiana it is easily distinguished by its laxer habit,
its few slender straight stipulary thorns, and its more
slender, beaked fruit. It is more nearly allied to R. Will--
mottiae, Hemsl., a plant figured at t. 8186 of this work,

January, 1913.

than it is to R. Webbiana, but R. Willmottiae is a much
smaller plant in all its parts than the subject of our plate.
In gardens R. sertata will be valued for its graceful habit ;
it makes long slender shoots which in the following season
become gracefully arched and bear in mid-June a profusion
of its beautiful flowers followed by richly coloured fruits,
while it has the finely cut, daintily formed leaves and the
glaucous stems that have rendered its allies R. Webbiana
and £. Willmottiae such favourites among wild roses. It
has so far succeeded well in stiff loam and gives promise of
being a more vigorous shrub in gardens than R. Webbiana.
So far the only experience of its propagation has been from
seed, but it is probable that, like R. Webbiana, it may be
increased by layers and perhaps by autumn cuttings,

The pleasing Clerodendron which forms the subject of our
illustration is a native of West Tropical Africa, where it has
been collected both in the region of the Lower Congo and
in Sierra Leone. In the latter country it occurs, according
to Mr. Scott Elliot, near rivers, and forms a handsome
fragrant shrub about four feet high. The plant from which
the material for our figure has been obtained is one which
was presented to Kew in 1910 by Captain Munro, R.N., of
Woodlands, Binfield. Grown in a tropical stove it flowered
in March and ripened fruits in June 1911, and again in 1912.
The nearest ally of C. Bakeri is C. Schweinfurthii, Giirke, a
species collected by Dr. Schweinfurth in’ Niam-niamland,
which is most easily distinguished by its almost entire leaves

January, 1913,

and its smaller, more acnte calyx-teeth. With care and
under stove conditions C. Bakeri may be grown into a
_ very decorative plant.

The Aroid genus Amorphophallus includes some seventy-
five species, widely spread in tropical and subtropical forests
in the Old World, of which about one-sixth have already
been figured in this work. That which forms the subject
of our illustration was discovered by Dr. A. F. G. Kerr in
the evergreen forest on the Doi Sootep mountain, in the
district of Chiengmai, Siam, at an altitude of 5000 ft.
above sea-level. Herbarium material of the plant was sent
by Dr. Kerr to Kew, while living tubers were forwarded
by him to the Botanic Garden of Trinity College, Dublin.
Here one of these tubers, grown under stove conditions,
flowered in April 1912, and supplied the material from
which our plate has been prepared. To the courtesy of
Professor H. H. Dixon, by whom the flower had been sent,
we are further indebted for the subsequent communication

January, 1913,

of the leaf produced by the same tuber. Specifically A.
corrugatus is readily distinguished from its nearer allies by
the spathe being open in front almost to the base, by the
remarkably corrugated appendix, and -by the purple ovaries
which are well exposed to view. The delicate shading of
the rather agreeably coloured spathe and spadix render this
species more ornamental than some other members of the
genus, :

Desoriprion.—Herb, tuberous, perennial; tuber up to
2 in. across, depressed subglobose. Leaf solitary, petiole

vaulted, obtuse, the base slightly convolute, margins slightly
undulate, glabrous, outside green and mottled with white
towards the base, the margins slightly purplish, inside

The pleasing little Aster here figured was discovered by
Mr. W. Purdom, while collecting on behalf of Messrs.
J. Veitch and Sons, at Tai-pei-shan in the province of
Shensi, Northern China. It flowered for the first time In
the nursery of Messrs. Veitch at Coombe Wood in May 1912,
and the material for our illustration was derived from one
of their plants. In habit A. Purdomii resembles some of
the forms of the widely distributed A. alpinus, Linn.,
figured long ago at t. 199 of this work, but it may be
- distinguished from this and indeed from all the other
Asters of Asia by the distinctly stalked ovate or ovate-

ae elliptic radical leaves with two or three small marginal

teeth, which are associated with flowering stems that are
_ Sanvary, 1918, ,

scarcely leafy and bear solitary heads. The species, which

is perfectly hardy, promises to be a desirable acquisition for
the rock garden ; it has a tufted habit and flowers freely.

Drscription.—Herb, about 6 in. high; stems 1-headed,
sparingly leafy below, elsewhere naked, greenish-purple,
pubescent with reflexed hairs. Leaves: radical few,
petioled, ovate or ovate-elliptic, obtuse, base rounded or

The Coelogyne here figured has long been regarded as
perhaps the most beautiful species in the genus. Easy to
cultivate in a warm greenhouse, it is generally grown and
is held in much esteem. This esteem is well deserved ; its
racemes of large white flowers are remarkably elegant ;
their value is enhanced by the fact that they are developed
in winter and last several weeks. They are consequently
much prized as materials for bouquets, wreaths and decora-
tions. Sometimes in this country specimen clumps over
six feet across and bearing hundreds of flowers have been
grown, but the finest display in our greenhouses fails to
convey any conception of the appearance of a forest-clad
spur in the Eastern Himalaya when C. cristata is in blossom.
Most abundant from Central Nepal eastward to Bhutan, the
species actually extends from Kumaon in the west to the
_ Fesrvary, 1913. :

Jaintea and Khasia Hills in the east. The plant appears
to have been first met with by Wallich near Khatmandu in
1819, and was described from Wallich’s material independ-
ently by Lindley in 1821 and by D. Don in 1825. The
species was introduced to cultivation by Mr. Gibson in 1837;
the first plant to flower in England did so early in 1841 in
the collection of Mr. G. Barker of Springfield, Birmingham.
As might be anticipated in a species with so wide a range, C.
cristata varies somewhat; two of the most beautiful varieties
known in collections are Lemoniana, which appeared many
years ago in the collection of Sir Charles Lemon, at Carclew
near Falmouth, and alba, which appeared first in the collection ©
of Mr. T. A. Titley, Leeds; a third very striking variety is
that known as mazima, introduced by Messrs, Sander and
Sons, St. Albans. In Sir ©. Lemon’s variety the hairs on
the lip are light citron-yellow in place of orange; in that
of Mr. Titley the flowers are pure white throughout. The
variety imported by Messrs. Sander has larger flowers with
petals and sepals of firmer texture than in the type.

Description.—Herb, epiphytic ; rhizome stout, creeping,
clothed with many imbricate sheaths; pseudobulbs some-
what separated, ovate-ellipsoid, ultimately longitudinally
wrinkled, 13-24 in. long, 2-foliate. Leaves lanceolate,
acuminate, somewhat plicate, distinctly 3-nerved, narrowed
to the base and sometimes shortly petioled, 5-12 in. long,

I in. wide. Scapes basal, 6-8 in. long, curved, clothed
below with imbricate sheaths ; racemes 5—7 -flowered ; bracts
spreading, oblong-lanceolate, acute, 13-2 in, long; pedicels
14-14 in. long. | Flowers showy, white, the lip usually with
yellow crests, Sepals and petals spreading, subequal, oblong,
somewhat blunt, undulate, about 2 in. long. Lip 3-lobed,
about 1} in. long; lateral lobes oblong, obtuse, embracing
base of column, somewhat reflexed at the tip; mid-lobe
suborbicular or wide rhomboid-ovate, blunt, 3-1 in. wide;
disk 5-crested ; crests shallow, breaking up into long pro-=
cesses and continued beyond the isthmus as a short triangular
crenate lamina, Column clavate, wide-win ged from a narrow
base, about 1} in. long. Pollinia 4, oblong, compressed,

cohering at the tip in a granular body.

The subject of our illustration, Rhododendron sublanceo-
latum, is an Azalea which is cultivated rather widely in
Japan as the ‘Chinese Azalea.’ It is undoubtedly very
nearly allied to R. indicum, Sweet, and observers so
competent as Dr. Buerger and Mr. Makino have even
suggested that our plant may be considered a variety of
that Chinese species. But &. sublanceolatum differs so
markedly from R. indicum, not only in the size of the
flowers but in the form of the calyx, that this suggestion
appears to be as unnecessary from the systematic as It Is
inconvenient from the cultural standpoint, and there is no
doubt that Mr. Craib is justified in treating the two as
distinct. It now appears, moreover, that £. sublanceolatum.

Fesrvary, 1913.

is not a Chinese plant at all, but that its home is in the
Loo-Choo Islands. The material from which our figure
was prepared was taken from a plant growing in the
nursery of Mr. R. ©. Notcutt at Woodbridge. The plant
selected was one of the richest as regards tint of corolla
in a large and rather variable batch in flower there in
June 1912. Under cultivation this species should receive
much the treatment that is required in the case of the
hardier forms of FR. indicum. In a peaty moist soil. it is
likely to prove robust in sheltered spots in the south-
western parts of the United Kingdom, but as to its capacity
to withstand the rigours of a really severe winter experi-
ence is wanting. It is increased by cuttings of moderately
firm wood in late summer placed in bottom heat.

Descriprion.— Shrub; twigs at first adpressed reddish-
setulose, hairs soon getting paler and at length disappearing ;
bark brown or tawny. Leaves lanceolate, narrow-elliptic
or oblanceolate, tapering to both extremities, mucronulate,
sometimes obtuse or almost rounded, margin strigose-ciliate,
when dry recurved, 1-23 in. long, 1-11 in, wide, coriaceous,
more or less pubescent on the nerves on both surfaces,
lateral nerves 5-9 on each side somewhat sunk above and
raised beneath, as are the transverse veins; petiole usually
under 4 in. long, adpressed reddish-setulose, the hairs soon
becoming paler and ultimately disappearing. Flowers
showy, terminal ; bracts deciduous, about 2 in. long,
reddish-strigose on the back; pedicels rather longer than
the bracts, reddish-strigose. Culyzx-lobes slightly unequal,
usually oblong, rounded at the tip, 3 lin. long, 2 lin. wide,
glabrous behind, margin strigose and glandular-ciliate.
Corolla over 2 in. long, lobed not quite to the middle,
lobes ovate- or elliptic-rounded. Stamens 10, included, fila-
ments pubescent in the lower half. Ovary oblong, adpressed-
strigose ; style rather longer than the stamens, glabrous.

The Broom which forms the subject of our illustration,
an old favourite in gardens, is useful in flowering at a
season, from the end of June to August, when the majority
of shrubs have gone out of bloom, Its tall erect racemes
make it very distinct among the hardy Brooms. The
wealth of blossom is followed by a great quantity of seed
which enables the stock to be easily renewed. But this
excessive fertility is associated with a tendency to be short-
lived, and it is therefore well to go over the plants as soon
as the flowers are past and cut away all save a few of the
old racemes. As the flowers are borne on the growths of

Fesrvary, 1913,

the current season this Broom may be pruned back in spring
to within an inch or two of the old wood. Its other re-
quirements are best met by a well-drained loamy soil and a
sunny position. Usually considered a Cytisus this plant has,
however, been treated by Bentham and Hooker as the type
of a very distinct monotypic section, Lembotropis, within
that genus, and Dr. Briquet, who has added to that section
another species, C. glabrescens, Sart., has transferred the
two allied forms composing it to the genus Genista, Linn.
In so far as regards the former conclusion there can be
little hesitation in following Dr. Briquet; to whichever of
the two genera our plant be referred its nearest ally is
C. glabrescens. But so far as the latter is concerned it
appears, as yet, preferable to follow Bentham and Hooker. |

The Heliotrope which we figure is a native of South-
eastern Brazil, Uruguay and Buenos Ayres. It bears a
strong general resemblance to the Sweet-scented Heliotrope,
H. peruvianum, Linn., figured long ago at t. 141 of this
work, but is readily distinguished from its fragrant
Peruvian congener by having odourless flowers. The
species has long been known in gardens both in Europe and
in North America, and we learn from Gray that it has
become subspontaneous in Eastern Florida and often appears
as a ballast weed about Philadelphia. The earliest descrip-
tion, which we owe to Poiret, appeared in 1813; in 1829
it was more fully described, apparently from South Brazil
specimens of Sellow’s collecting, by Chamisso. There has
never been any confusion between HH. anchusaefolium and
fT, peruvianum, whether in herbaria or in gardens. But
there has been, and still often is, both among horticulturists
and botanists, a tendency to confuse with Poiret’s plant
that described by Sir W. J. Hooker at t. 3096 of this work
as Tournefortia heliotropioides. The two plants are, how-
ever, specifically quite distinct, for that described by Hooker

has broad elliptic leaves with petioles three-quarters of an
Feprvary, 1913,

inch long, while its flowers are somewhat smaller than those
in Poiret’s plant with the corolla less deeply lobed. But if
the description given by Hooker be accurate, and there is
no justification for the formation of a contrary conclusion,
the two plants belong not only to different species, but to
distinct genera. In the plant named /. anchusaefolium by
Poiret, the fruit at first is divided into a pair of two-seeded
mericarps, each of which finally divides into a couple of
one-seeded nutlets; just before this final division, and
marking the plane in which it occurs, we find a groove
round the fruit. In the plant named by him Tournefortia
heliotropioides, the fruit is described by Hooker as a four-
stoned berry. Dr. Giirke, accepting the general but
erroneous belief that Poiret’s plant is the same as Hooker’s,
and further adopting the description of the fruit given by
Hooker as accurate, has transferred Tournefortia heliotro-
pioides, Hook., to the genus Cochranea as C. anchusaefolia,
Giirke. Hooker’s original description, however, points
rather to his plant being, as he originally said, a Tourne-
fortia, But, however this may be, the popular belief which
confuses Hooker’s plant with that now figured, is one that
cannot be sustained. For the material from which our
illustration has been prepared we are indebted to Miss
Willmott, in whose garden at Warley Place it flourishes
freely. It also thrives well and flowers profusely at Kew,
but requires to be protected from cold in winter,

The Agave which the late Professor Todaro named A.
Haynaldii, in honour of the distinguished botanist Arch-
bishop Haynald, is one that flowered in 1878 in the garden
of Mr. Whitacker at Ai Colli near Palermo, and _ was
probably originally obtained from some collection in England.
The plant from which our illustration has been prepared is
one sent by Dr. H. Ross from the Palermo Botanic Garden
in May 1897 to that of the late Sir T. Hanbury at La

Fesrvary, 1913. | ‘

Mortola. It may therefore be accepted as an authentic
example of A. Haynaldii, though it is found on comparing
the La Mortola plant with the description and figure
supplied by Todaro that there is some degree of variability
in the size, disposition and direction of the lateral spines
and in the dimensions and arrangement of the flowers.
The horny leaf-border is less continuous and is generally
interrupted in the middle in the La Mortola example; its
flowers, too, are somewhat smaller and are generally disposed
in twos or threes, less often in fours; there are never, as in
the original Palermo plant, as many as eight in one cluster.
The species to which A. Haynaldii bears the greatest
resemblance is that described in 1900 as A. expatriata by
Dr. Rose ; a comparison of the figures and descriptions of the
two plants shows that they are very, perhaps too closely
related. A member of the ‘ Marginatae’ group of Littaeas,
easily recognised by the horny border of the leaves and
by the short perianth-tube with lobes which embrace the
stamens as soon as the anthers are ripe, A. Haynaldii is
readily distinguished from the others by its larger size.
The La Mortola example here figured showed signs of
flowering towards the end of September 1910, the spike
pushing with considerable rapidity and the first flowers

opening in November; the apical flowers opened in
February 1911.

Description.—Shrub, stemless; rosette with about 80
leaves, some 6 ft. wide, 4 ft. high. Leaves erecto-patent or
slightly incurved, 34-34 ft. long, 2 in. thick and very
biconvex at the base, narrowed and flat towards the middle
and somewhat channelled below the point, lanceolate-
ensiform, about 33-44 in. wide above the middle, thence
tapering gradually into a long point with a wide-channelled,
nearly 3-quetrous, brown end-spine, about 1 in. long,
constricted towards the base into a long neck, 21 in. wide,
convex underneath but gradually thinner towards the point,
coriaceous, dark glossy green, without darker lines on the
back and only in young plants with a pale band on the
upper surface; the margin with a spiny horny border,
usually interrupted about the middle of the leaf, when young
chestnut brown, soon becoming ash-grey, slightly repand
between the spines, the lowest small and close, those of the

middle of the leaf 24-43 lin. long, deltoid-uncinate from a
broader base, generally with an intercalated smaller, occasion-

The Cytisus which forms the subject of our illustration is
a hybrid raised at Kew in 1900. A plant of C. scoparius,
Link, var. Andreana, Hort. (Genista Andreana, A. Puiss.),
was isolated in a greenhouse and the flowers were fertilised
with the pollen of the well-known White Portugal Broom,
C. albus, Linn. There is thus no doubt as to its origin, and
it may be remarked in passing that it is as yet the only
hybrid broom intentionally produced, other hybrids being
the result of chance crosses made by insects. Andreé’s
Broom, now well known in gardens, was discovered in
Normandy about thirty years ago; it differs from typical
C. scoparius in having rich brown-crimson wing-petals, the
rest of the flower being yellow asin thetype. The flowers of
C. albus are milky-white, sometimes slightly tinged with rose.
In C. Dallimorei the yellow of the female parent has almost
disappeared and the whole flower has assumed some shade
of rosy-purple, the wing-petals alone showing some approach
to the rich colouring of the wings in Andreé’s Broom. Onl 4
two seedlings were raised from the original cross—one wit
Marcu, 1913.

rosy flowers (C. Dallimorei), the other with yellow flowers
as shown at fig. B of our plate. From this second, yellow-
flowered plant has been raised a seedling which has cream-
coloured flowers touched with rose, as shown at fig. C of our
plate. This last is a very promising garden plant with
much the character of C. praecox, Hort., but without the
offensive odour of that broom. The material for our plate
has been derived from the original plants at Kew referred
to above. As a garden plant C. Dallimorei is of great
promise. It has scarcely the vigour of either parent; the
original plant, indeed, was for several years of feeble
growth and vigour, and it was only when a twig was made
strong enough to graft on a young Laburnum that its
continued existence became assured. This grafted plant
was the first to flower, and the stock has since been increased
from it by the same method. The hybrid produces good
seed and a number of plants have been raised, the flowering
of which will be watched with interest.

The Magnolia which forms the subject of our plate
differs from all the other species in cultivation in its thin
narrow leavesand slender twigs. The flowers on the whole
recall most readily those of J stellata, Maxim., figured at
t. 6370 of this work. In that species, however, all the
perianth leaves are petaloid, whereas in MM. salicifolia, the
species now figured, the perianth is differentiated into a
calyx and acorolla. In this regard M. salicifolia agrees
with its nearest ally, 1. Kobus, DC., but 1s readily dis-
tinguished by its Janceolate leaves and glabrous leaf-buds.
According to Professor Matsumura J/. salicifolia occurs 1n
many localities in Nippon and is also found on Kiusiu;
Mr. Shirasawa gives its range of altitude as from 1700 to
4500 feet above sea-level, and states that it naturally prefers
a deep soil. The plant from which the material for our
Maron, 1918.

'

figure was obtained is one of a batch purchased for Kew
from a Japanese nursery in 1906. A few flowers were first
produced in the spring of 1911; probably as the result of
the great heat which marked the summer of 1911 a profuse
crop of flowers appeared in March and April 1912. The
Jeafy twig in our figure was drawn at the end of May, the
plant at flowering time being quite leafless. M. salicifolia
promises to make an elegant tree, an unusual feature
in the genus. The Kew plants are growing admirably in
a mixture of sandy loam and peat; the latter is useful in
encouraging newly planted trees to become established, but
is not essential at later stages, and therefore need only be
placed near the roots of newly planted trees. We have so
far no experience in the propagation of this Magnolia, but it
will certamly be best on its own roots, so that for some years
Japanese sources must be relied upon for trees and seeds.

Desoriprion.— Tree, deciduous, slender, 15-20 ft. high,

The fine Aloe here figured was discovered by Dr. R.
Marloth first at Lobatsi in Bechuanaland; later near Lady-
smith in Natal; still later on the Klip River Mountains
near Johannesburg in the Transvaal. _‘l'ransvaal specimens
flowered first under cultivation in the Grahamstown Botanic
Garden in July 1908. A plant sent by Dr. Marloth in 1905
from the Klip River locality to Sir Thomas Hanbury, at La
Mortola, flowered there in April 1912 and provided the
material for our illustration. The species, however, had
already reached Europe; the plant described by Mr. Baker
Makgcu, 1913. —

as A. supralaevis, B Hanburii, from European cultivated
specimens, cannot be distinguished from that figured by Mr.
Medley Wood as A. Marlothii, and Mr. Medley Wood’s Natal
plant is identical with the Transvaal one described by Mr.
Berger. As Wood remarks, A. Marlothii had, until Berger
defined it, been confused in South Africa with A. ferox,
Mill., figured at t. 1975 of this work, and it is possible that
there, as in Europe, it may have been confounded with
species other than A. ferox, which have themselves been
misunderstood. This confusion cannot be unravelled here ;
Mr. Berger’s species is, however, a very distinct one which,
while approaching A. feror as regards the colour of its
flowers, is in other respects more nearly allied to A. Galpini,
Baker, in which the flowers are red.

The Ruellia here figured was originally discovered by Mr.
J. C. Harvey .in forests on the northern or Atlantic side of
the Isthmus of Tehuantepec in 1904. In 1911 Mr. Harvey
sent to Kew, from his garden at Sanborn, Vera Cruz, a living
plant which flowered in August 1912 and provided the
material for our plate. In a warm house, under the con-
ditions suitable for Begonias and Gesneriads, R. Harveyana
has grown freely and formed a trailing shrub of somewhat
straggling habit. In its native forests, Mr. Harvey informs
us, its flowers, though usually coloured as in our plate, ale
sometimes white. &. Harveyana belongs to a group of
species of Ruellia where there is much confusion. Among
_ these it approaches most closely that usually known as £.
lactea, Cav., described and figured by Cavanilles in 1794
from a Mexican plant growing in the Madrid garden, stated
to have corollas of a blue so diluted that they might almost
Manca, 19138, -

be said to be white; its sepals are said to be subequal and
subulate with awn-like points, so that the plant, whatever it
may be, is not 2. Harveyana. According to Loudon, a plant
introduced by the Marquis of Bute in 1796 was accepted as
Cavanilles’ plant, and early in the nineteenth century was in
cultivation at Kew, Parisand Berlin under Cavanilles’ name.
Its identity is vouched for by a specimen, collected by Gay
in the Jardin des Plantes in 1817, now in the herbarium at
Kew. This plant was accepted by Nees as R. lactea, Cav.,
and described by him as Cryphiacanthus lacteus. It agrees
fairly well with wild specimens collected by Andrieux
between Acatlan and Chila in lower western Puebla. No
specimens of Cavanilles’ original plant appear to exist, and
it is impossible to say whether the differences between 2.
lactea, Cav., and the plant of Nees be due to faulty delinea-
tion or to natural variation. The point that is of consequence
is that if the characters given by Cavanilles exclude R. Har-
veyana from R. lactea, those of the specimens accepted as £2.
lactea make the recognition of our plant equally necessary.

Drscriprion.—Herb, perennial; stems rather slender,

Though introduced, according to Aiton, in 1773, the
Cherry which forms the subject of our illustration has
never been common in this country. As long after its
introduction as 1842, it appears to have been unknown, in
the living state, to Loudon. It is nevertheless a handsome,
free-flowering species, as is shown by our plate, prepared
from material gathered from a small tree presented to Kew
by the Arnold Arboretum in 1910. It is worthy of a place
in thin woodland where our native P. avium and P. Padus
succeed. One of the most widely spread of North American
trees, P. pennsylvanica extends from Newfoundland and the
shores of Hudson’s Bay in the north, to North Carolina and
Tennessee in the south, and westward to the inland slopes
of the Rocky Mountains. Its nearest ally is P. emarginata,

purely western species, confined to the area from California
to British Columbia, and is distinguished from the species

The systematic position of the genus Sansevieria, Thunb.,
familiar and economically interesting as that which includes
the plants yielding the fibre known as Bowstring Hemp, has
been a subject of difficulty and debate. Transferred, for
what at the time appeared to be valid reasons, by the
authors of the “ Genera Plantarum” in 1883 from Liliaceae
to Haemodoraceae, it has recently, as the outcome of renewed
investigation, been replaced in Liliaceae next to the genus
Dracaena, Vand. The species which forms the subject of
our plate, S. aethiopica, is one of those upon which Thunberg
founded the genus, and has been in cultivation in Europe
for over a century, yet it has never, so far, been figured
under its own proper name. This has been due to its
having been mistaken for S. zeylanica, Willd., a plant till
recently very imperfectly known, but one which, now that
wild specimens have been obtained for the Kew collection
from Ceylon, is found to be altogether distinct from the

ApRiL, 1913. ;

subject of our illustration, which has leaves that are more
numerous to a growth, and are much shorter and thinner,
with a whitish in place of a green tip and red or whitish
margins. In S. aethiopica, too, the flowers are larger than
they are in S, zeylanica. The plant which has supplied the
material for our figure was transmitted to Kew in 1895 by
Mr. C. Howlett, Curator of the Botanic Garden at Graaf
Reinet, and was collected by him in the Uitenhage division
of Cape Colony. From Uitenhage it extends inland to
Griqualand West, the Transvaal and Rhodesia, but without
pene eastwards as far as Natal or westwards to Namaqua-
and, Grown in a warm greenhouse S. aethiopica thrives
_ well and flowers at intervals; the flowers figured were

produced in July 1909. Like other species of the genus,
S. aethiopica is easily propagated, either by division of the
rootstock or from sections of the leaf, which strike readily
when placed in sandy soil in a warm house and soon form

a basal growth bud.

Descriprion.— Undershrub, suceulent, stemless. Leaves
13-30, somewhat tufted, suberect or somewhat spreading,
5-16 in. long, 3-2 in. wide, }-1 in. thick, linear-lanceolate,

times transversely banded, somewhat glaucous, with reddish
or white edges. Injlorescence 16-30 in. long, with 5-7
acuminate, membranous sheaths each 3—23 in. long near the
base, the upper half spicately racemose ; bracts membranous,
spreading or reflexed, }-} in. long, ovate-lanceolate, acute,
each subtending 4-6 Howers with pedicels 3-1 in. long,

jointed above the middle. Perianth white, tube 2-1 in.

The American Crab here figured is one of a well-marked
group of three distinguished, in the Malus group of the
genus Pyrus, in flowering latest of all and in having violet-
scented flowers. The better known of the other two is
Pyrus coronaria, Linn., a species figured at t. 2009 of this
work, which is distinguished by having its leaves truncate
or slightly cordate and by having them, when mature,
nearly or quite glabrous. The other species, P. angustifolia,
Ait., also differs in having its leaves glabrous at maturity
and is very readily distinguished in having fruits that are less
than an inch in diameter. It is, besides, a Southern species
which reaches Florida, whereas P. ioensis has its own well-
defined area west of the Alleghanies; it is described as
being the common Crab of the Mississippi basin. As a
tree for gardens P. ivensis is strongly to be recommended,

Arrin, 1913,

especially for the fragrance of its blossom, which is borne
in late May and early June. There is a double-flowered
variety, more generally met with in gardens than P. wensis
itself, which is erroneously termed sometimes P. angusti-
folia, flore pleno, sometimes P. coronaria, flore pleno; its

Owers are 2—3 inches across. So far as is known the true
P. angustifolia, which was grown in English gardens a
century and a half ago, is not now in cultivation in this
country.

Descriprion.— Tree, deciduous, 20-30 ft. high; trunk
1-13 ft. in diameter; crown rather loose and open; twigs
slender, sometimes spine-tipped, at first covered with a soft
white wool which turns brown and falls almost entirely
away by winter. Leaves petioled, ovate-rhomboid or ovate,
acute, base cuneate, margin coarsely irregularly often
double toothed, on the virgin shoots of the year 3-5 in,
long, 2-33 in. wide, with frequently one or two pairs of
lanceolate lobes near the base divided halfway to the
midrib, on the flowering twigs 2-3 in. long, 14-2 in. wide,
scarcely lobed; all dark green above and glabrous except
for a loose tomentum at first opening, very tomentose

The Cocculus here figured is a scandent shrub, native of
Eastern Asia, where it extends from Japan and Northern
China to the Philippines. The leaves are variable in outline,
and the form of C. trilobus with entire leaves, here depicted,
is often known as C. Thunbergii, DC. Like other species
of the genus, C. trilobus is easily cultivated and propagated,
but to get it to fruit freely it needs all the sunshine
possible. The flowers figured were produced in 1912,

Aprin, 1913.

but the fruits shown were gathered in November 1911,
and it was no doubt owing to the great heat of that
year that the crop was so fine. Even in ordinary
seasons, however, the plant is well worthy of cultiva-
tion; grown up stout limbs of oak set in the ground it
makes an elegant climber, twining itself tightly round the
smaller branches. This Cocculus was introduced to cultiva-
tion from Japan by Professor Sargent, Arnold Arboretum,
some twenty years ago. It is perfectly hardy.

_ Description.—Shrub, climbing ; branches twining, softly
hairy. Leaves petioled, ovate entire or at times 3-lobed
with the mid-lobe much larger than the side lobes, obtuse or
acute, apiculate, base rounded or cordate, 2-33 in. long,
1{-22 in. wide, firmly herbaceous, palmately 5-nerved at
the base, closely reticulate, puberulous above, more or less
pubescent beneath ; petiole 3-11 in. long, soft hairy. Cymes
1-sexual, solitary in the leaf axils or aggregated in a terminal
bracteate thyrse; bracteoles paired, close to the base of the
calyx, ovate oblong, very small. Male: Sepals 6, the
outer 3 ovate, under 1 lin. long, the inner 3 wide ovate,
1} lin. long. Petals 6, ligulate, 14 lin. long, 2-fid at the
tip, the lobules subulate sometimes a second time 2-fid, their
margins inflexed below. Stamens 6, opposite the petals;

The Rock Rose which forms the subject of our figure is
one which has been grown in the Kew collection for a
quarter of a century, but having been received under
another name and having since its receipt been ‘several
times propagated its origin is not known. That it is a
natural hybrid between Cistus ladaniferus, Linn., figured
long ago at t. 112 of this work, and C. monspeliensis, Linn.,
has long been believed, for it has been met with in a wild
state in Hérault growing along with the two parent species.
The belief has been confirmed by the late Mr. Bornet, who
obtained C. Loreti experimentally by crossing these two
species. The special interest of this Rock Rose to
cultivators lies, however, in the fact that it is one of the
hardiest in the genus; it has withstecd at Kew without injury,

APRIL, 1913,

over twenty degrees of frost, and there are but few species
of Cistus of which this can be said. It is also undoubtedly
one of the most beautiful of the Rock Roses, flowering very
profusely and making a striking display for several weeks
from Midsummer onwards. Messrs. Rouy and Foucaud
recognise two distinct forms, both of which have been met
with in a wild state; the first, albiflorus, has petals with no
crimson spot near the base; the second, maculatus, which
is that now figured, has petals with a crimson a a
C. Loreti is easily increased by cuttings made of late
summer shoots. Owing to its dislike of root disturbance it
should be grown in pots until planted out permanently.
A light sandy soil and the sunniest situation available
should be given to it. :

Jicum, Linn., also a North American species. /7. Kalmianuin
is a native of the Great Lake region of North-Kastern
America and extends from Ontario and Western New York
to Illinois, Wisconsin and Michigan. The best-known
habitat of the shrub is on the banks of the Niagara Gorge,
but it is now uncommon in nature as well as in gardens.
For its reintroduction Kew is indebted to Mr. J. Dunbar,
Assistant Superintendent of the Rochester Parks, N.Y., an
eager and accomplished student of the North American flora.
In sending seeds in March 1911, Mr. Dunbar remarked
that the plants from which they were collected “ were found
at Rose Hill, Ontario, Canada, on the opposite side of Lake
Erie from Buffalo, growing in great abundance on the bleak

sandy coast-line.” The plants raised from these seeds
flowered in August 1912, and from one of them our figure
was prepared. A characteristic appearance is given to this
species by the presence of axillary tufts of leaves on the
shoots of the current year. These tufts, which are usually
composed of two pairs of leaves, are borne on greatly
abbreviated “short-shoots.” H. Kalmianum thrives very
well with other St. John’s Worts in good loamy soil, and is
easily increased by cuttings as well as by seeds.

AUTHOR'S PREFACE
TO THE SIXTH (SUPPLEMENTARY) VOLUME

The last volume of the “ Coleoptera of the British Islands” was
published in 1891. In the preface to the first volume I expressed
a hope that the work might, at all events, prove of some help towards
encouraging the study of our native Coleoptera. As far as I can
gather, this hope has been, in a measure at least, realised, and to judge
by the results, as embodied in this volume, it will be seen that a great
deal of work has been done at the Order during the past twenty years.
Moreover, that work is by no means exhausted. Almost every month
new species are being recorded. The present volume was practically
ready some months ago, except for the plates, and the large list of
addenda that has accumulated during that period shows the interest
that is being taken in our Coleoptera at the present time. Dr. Sharp
is of opinion that our indigenous species will be found in the future to
number at least 4000, and this makes it evident that there may be
much left to discover.

When it appeared that there was need of a supplement to bring the
work up to date, Mr. Donisthorpe, hearing of my intention to prepare
one, kindly offered me the use of the list of localities, etc., which he
had for some years compiled from various records. I therefore asked
him if he would collaborate with me, and Iam much indebted to him
for his help. The first part of the work is, for the most part, miue,
and I hold myself responsible for it; while Mr. Donisthorpe has
provided the part relating to fresh localities, and the excellent paper
on the British Myrmecophilous Coleoptera, and has also undertaken
the arrangement of the plates.

PUBLISHERS’ NOTE

“Tue CoLEOPTERA OF THE BritisH IsLanps” was originally published
in five volumes between 1887 and 1891. It was intended to provide
a short account of our indigenous Coleoptera, with some reference
to their localities and habits, and, where possible, to their life history ;
subsequently it was increased in scope. The work is one of great
importance and value to all Coleopterists, and a valuable addition to
the present list of entomological works. The large paper edition of the
first five volumes, containing 180 plates, carefully drawn and coloured,
and representing upwards of 2300 species, is almost out of print.

The large paper edition of the present (sixth) volume, contains
20 coloured plates, with drawings of 255 species or varieties, making a
total of over 2550 species represented in the entire work.

Attention is called to the list of other entomological works uniform
with this series, printed on the back of this leaflet.

The handsome Himalayan Rhododendron which forms
the subject of our illustration, though it has Jong been in
cultivation in this country, does not appear ever to have
been common in collections. In certain parts of Sikkim it
seems to be plentiful, and in his original description Sir
J.D. Hooker speaks of the species as abundant in the wooded
valleys and on the spurs of all the mountains at an elevation
of 12-14,000 feet above sea-level. It is not, however,
abundant in all the valleys of Sikkim at this elevation,
though it probably is so in most of those explored by
Hooker, and as regards the valley of the Zemu, a tributary
of the Tista, Hooker’s account is fully confirmed by recent.

plant which flowered in the Himalayan house at Kew in
April, 1911. It was raised from a graft presented by Miss
A. Mangles, in whose garden at Littleworth there is a large
bushy specimen of &. Wightii which has long been grown in
the open. It flowers freely, however, only in certain
seasons, but it is nevertheless probably quite as hardy as
the other Sikkim Rhododendrons from the same elevation.
The flowers are usually of a rather deeper yellow than those
represented in our plate. Another point in which the plant
now figured deviates from the figure by Sir J. D. Hooker
cited above is in more lax inflorescence with longer pedicels.
In all other respects, however, it agrees well with the
original illustration.

The Deutzia which we here figure was originally dis-
covered by the Abbé David near Moupine in Szechuan and
was subsequently collected in various localities in the same
province by Mr, E. H. Wilson at altitudes of from 5,000 to
9,000 feet above sea level, when collecting on behalf of
Messrs. J. Veitch & Sons, in 1901, and again during his
latest Chinese journey. The species was first introduced
into cultivation through the Coombe Wood Nursery of the
Messrs. Veitch in January, 1902, as an unnamed Deutzia.
In 1905 it was named D. Veitchii on their behalf by Mr,
Wilson, and under that name it has become well known and
widely established in collections and has been recognised by
the Royal Horticultural Society. Thanks, however, to the
kindness of Professor Lecomte, who has kindly placed at
our disposal for study the specimen on which Mr. Franchet's

original description of D. longifolia was based, it has been
possible to ascertain that the name suggested by Mr. Wilson
is superfluous. In 1908 a further supply of seeds was
received at Kew from Professor Sargent, Arnold Arboretum ;
from this consignment was raised the plant from which the
material for our illustration has been obtained. In 1909
yet another supply of seed reached Messrs. Veitch. The
species varies slightly in size of flower and in depth of
colouring ; one of the best of its forms is that which was
raised by Messrs. Veitch in 1902, and was again raised at
Kew in 1908, Like all the other members of the genus,
D. longifolia rejoices in a rich loamy soil and can be
propagated by cuttings of moderately firm wood in July
and August. In low-lying districts its flowers are liable to
be damaged by late spring frosts, but on the whole it may be
regarded as one of the most ornamental of Chinese Deutzias.

bark flaking, flakes thin. Leaves lanceolate, acute or often

The Leguminous genus Strongylodon is widely spread
from the Mascarenes to Melanesia with, however, two more
or less distinct centres in Madagascar and in the Philippines,
in each of which areas three or four endemic species appear
to occur. The oldest of the known species is one which is
widely spread in Polynesia from the Sandwich Islands to
Fiji, first described in 1786 by the younger Forster as
Glycine lucida, and in 1836 treated by Vogel as the basis of
this distinct genus undér the name S. ruber. Thirty years
later Seemann again dealt with the plant under the more

Mary, 1913.

strictly accurate name S. lucidus. About the same time
Thwaites discovered what he assumed to be the Polynesian
plant on the Ceylon coast and used for it Vogel’s name;
thirty years later it was found that the Ceylon form is
particularly abundant on the Andaman coast. In 1886,
however, Drake del Castillo pointed out that the Ceylon
Strongylodon is not the same as the Polynesian one. ‘This
Ceylon plant, which extends from the Andamans and Ceylon
to Christmas Island, North Australia, New Guinea and New
Caledonia, is readily distinguished from the Polynesian
species by its much smaller flowers and its smaller pods.
It is now found that this littoral species also extends west-
ward from Ceylon to Madagascar; the material on which
our plate is based was raised by Messrs. Charlesworth &
Co., Haywards Heath, from a seed received by them from
a correspondent in Madagascar, and was communicated
by them for identification in December, 1912, and was
recognised as being the Strongylodon ruber of the coasts of
Ceylon and the Andamans. Since, however, the name
S. ruber belongs, as a synonym, to the Pacific S. lucidus,
and since Drake, when pointing out that the two are
specifically distinct, did not suggest a name for the more
western plant, it has been necessary to provide one now.
S. pseudolucidus, Messrs. Charlesworth find, thrives satis-
factorily and is easy to grow in a warm conservatory.

The handsome Dendrobium here figured is a native of
the Philippines, whence it was introduced by Messrs.
Sander & Sons, St. Albans, with whom it flowered for the
first time in September, 1912; the notes published in the
previous year were prepared from dried specimens. A plant
purchased for the Kew collection from Messrs. Sander flowered
in the tropical Orchid House in October, 1912. In the pre-
paration of our plate use has been made of this latter plant

and of photographs kindly supplied by Messrs. Sander, A
member of the section Formosae, D. Schuetzei is nearly allied
to D. Dearei, Reichb. f.,and to D. Sanderae, Rolfe, the latter
figured at t. 8351 of this work, both of which are Philippine

species. Our plant has, however, larger flowers than either,

with a much shorter obtuse mentum, so that it has more of

the general appearance of the Indian D, formosum, Roxb.,

though it is without the large orange-yellow disk of the

latter. In D. Schuetzei the flowers are white with some

green on the disk of the lip and a tinge of purple at the

The small Saxifrage which is here figured is a native
of Bulgaria, where it was first found in 1893 on Mount
Rhodope by Stribrny. Velenovsky, who at first thought
that it might be considered a variety of S. porophylla,
Bertol., subsequently adopted the view that it ought to be
considered a distinct species, a view that further. investiga-
tion has served to confirm. In 1906 it was again gathered
in its original locality by Adamovié, and in that year the
plant from which our illustration has been prepared was
obtained by purchase from Mr. Sundermann, of Lindau,
Bavaria. “According to Velenovsky S. Stribrnyi 1s in
nature found in association with S. Frederici-Augusti, Bias,
the affinities of which, of S. media, Gouan, and of the
present plant have already been discussed at t. 8308 of this

work. The affinity of our plant is closest with S. media,
figured at t. 7315 of this work, but it is easily distinguished
from S. media by its more branched inflorescence with
nodding flowers. S. Stribrnyi is, perhaps, seen to most ad-
vantage when cultivated in a pot in a cold frame, but it.
also does well in the Rockery, where it flowers sometimes
as early as February. The plant figured, which had been
grown in a frame, flowered in April, 1909. The species is
a perennial one with clustered rosettes, but at Kew these
clusters do not become enlarged as in some of the other
species of the group to which our plant belongs.

Descriprion.—Herb, tufted ; crowns short, densely leafy ;
flowering stems erect, branched, sparingly leafy, patently
glandular-pilose. Leaves rosulate at the base, spreading,
sessile, spathulate-oblanceolate, somewhat mucronulate, up
to 1 in. long and } in. wide, fleshy, glaucous, beset, above
with intramarginal pits barely 1 lin. apart, keeled beneath, —

The Rhododendron now figured, which was_ originally
named in compliment to Mr. Augustine Henry, its first
discoverer, appears to be one of the most hardy and free-
growing of the new Chinese species of the genus and
thrives in any open soil free from lime, although the ideal
soil is one of a peaty nature. It can be increased by
cuttings made of the current year’s growth taken in late
July when the wood is becoming firm. The plant from
which our illustration has been prepared was obtained for
Kew from Messrs. J. Veitch & Sons in 1908, their stock
having been raised from seeds procured by Mr, E. H.
Wilson, who met with the species both in Hupeh, where it
had formerly been gathered by Mr. Henry, and in
Szechuan. It is, however, probable that there was an
independent and earlier introduction of this species to

European gardens, because it was already not only in
cultivation but in flower in the garden of Mr. M. L. de
Vilmorin at Les Barres in 1904. The flowers vary some-
what in colour from white to pink and pale purple, with
yellow or orange blotches on the dorsal lobes of the corolla.
Its nearest ally is R. lutescens, Franch., but from this it is
easily distinguished, even when out of flower, by the line of
persistent hairs on the midrib of the leaf beneath.

bark turning brown and with the scales more scattered and
hardly visible. Leaves lanceolate or wide lanceolate, acute or
subacuminate, mucronate, base wide cuneate, 14-22 in. long,
3-4 in. wide, firmly papery, green and puberulous above,
paler beneath and hirsute with long persistent white hairs

The St. John’s Wort which is here figured is a native of
the South-Eastern United States, and is widely distributed
from South Carolina and Georgia to Tennessee, Alabama and
Texas. Though it has not before found a place in our
pages, Hypericum aureum is an old plant in gardens, and the
example from which our plate was prepared is one of a
batch raised from seed saved at Kew. It can also be
quite easily 2s fe by cuttings in late summer.
Among the St. John’s Worts grown in gardens, //. aureum
is well marked by its deflexed yellow petals, its orange
stamens and its leafy sepals. It is useful, like most of the
cultivated Hypericuins, for making a display in August
when few woody plants are in blossom. It is quite hardy

Jung, 1913, :

‘and thrives best in a well-drained loam of moderate
richness. In habit it differs from many of its congeners
in forming a distinct stem which gives the plant the
appearance of a miniature tree. Botanically 7. aureum is
most nearly related to H. myrtifolium, Lam., another North
American species which has 3 styles and a I-celled ovary,
as well as foliaceous sepals. But from H. myrtifolium our

plant is readily distinguished by its narrow in place of
cordate leaf bases,

The subject of our illustration, Amelanchier oligocarpa, is
a denizen of cold swamps and mountain bogs from Labrador
southward to the shores of Lake Superior and the northern
portion of New York State. In habit it is the most low-
growing species of its genus, and coming as it does from a
more northerly habitat than any other, it 1s exceedingly
hardy. Yet it has always been one of the rarest of shrubs
in our collections, some form of A. canadensis, Torr. & Gray,
being as a rule supplied under the name, a circumstance
which may perhaps have helped to account for its occasional
treatment asa variety of A. canadensis. In spite of this,
A, oligocarpa is singularly unlike A. canadensis, and is well —
and easily distinguished by the few-flowered inflorescences
with one to three, very rarely four blossoms. The species
thrives best in a good loamy soil. The plant from which

The Osbeckia which forms the subject of our illustration
appears to have first attracted the attention of Dr. F.
Buchanan (afterwards Hamilton) when he accompanied the
embassy of Captain Knox to the Court of Nepal in 1802.
None of the seeds then sent by him to Dr. Roxburgh, the
superintendent of the Botanic Garden at Calcutta, appear
to have reached Europe in a germinable state, and it was
not until the period from 1816 to 1822, when Dr. Wallich,
then in charge of the Calcutta garden, was successful in
obtaining Himalayan seeds, that the plant was introduced to
English horticulture. These seeds found their way to
various prominent nurserymen, and by 1820 the plant was
already under cultivation, by whom first raised is uncer-
tain. In 1822 Messrs. Shepherd of Liverpool advertised
the species as raised by them from seods collected near
Khatmandu in Nepal. In the manuscript of his *¢ Exotic

June, 1913.

Flora,” Sir W. J. Hooker. described this species as
O. crinita, but before the description appeared, the name
was altered to Q. stellata which had already been pub-
lished by Dr. D. Don. The species, which extends from
the North-Western Himalaya to China, has again been
introduced to Europe from the Calcutta garden ; the material
for our figure has been derived from a plant raised from
Sikkim seeds sent from the Royal Botanic Garden, Calcutta,
by Major Gage. The plant is easily grown, and under
ordinary greenhouse conditions it forms a shrub about two
feet in height which flowers in autumn.

Agave Warelliana was first described by Mr. Baker from
the famous collection of Mr. Wilson Saunders. It is still
an uncommon, but is a very attractive plant in gardens.
During the summer of 1912 it flowered at La Mortola in
the garden of Lady Hanbury, and also in the garden of
Professor G. Roster at Ottonella in the Island of Elba,
From the plant which flowered at La Mortola was derived
the material from which our figure has been prepared.
‘June, 1913. at

Among the Agaves generally included in the section Littaea
on account of their cylindrical inflorescences, our species
belongs to a special group the members of which have
tubular flowers with recurved segments, as in A. polyacantha,
€. Koch. Its nearest allies are A. macrantha, ‘Tod. and
A. chiapensis, Jacobi. All have rather large flowers and
bracts. But in A. chiapensis the flowers are smaller than
in A, Warelliana and have a shorter tube; the leaf characters
also differeven more markedly. Between A. mucrantha, Tod.,
and A. Warelliana there are relatively minor differences,
especially in the shape of the leaves and their marginal
teeth, so that it is not impossible that the two may be
extreme forms of one rather variable species. If this view
be adopted, Mr. Baker’s name has priority. The. Agave
which flowered at Lyon in the Pare de la Téte-d’Or in
1869 and was described as A. chiapensis by Jacobi (Abhandl.
Schles. Ges. Naturw. Abth, 1870, p. 164) is another form
of this species and is not the same as the original A. chia-

pensis described by Jacobi in 1866 (Hamb. Gartenz.
xxii. 213),

Description.—Shrub. Rosette acaulescent or very shortly
caulescent, with about 75 leaves, over 3 ft. high and nearly
6 ft. broad, emitting a few suckers and, after flowering,
branching from the axils. Leaves about 28-29 in. long

The Composite here figured has been in continuous
greenhouse cultivation for over seventy years. A native
of Central America, it is met with wild at from 3,000 to
6,500 feet above sea-level from Southern Mexico to Costa
Rica. The monotypic genus Podachaenium to which it
belongs is rather closely related to Verbesina, Linn., but :
readily distinguished by its uniformly opposite leaves =
its stipitate achenes with few pappus scales. When first

described it was referred by Lagasca to Ferdinanda, and
the erroneous name F”. eminens is even yet frequently em-
ployed for our plant in seed-lists and garden catalogues.
The plant is of vigorous growth and easy culture provided
it be given a sunny.and airy position. © It may be propa-
gated by seeds or by cuttings of young growths in sandy
soil in a moist, warm frame. Unless frequent stopping of
growths be practised the plants become somewhat straggling
and unbalanced. ‘To ensure free flowering in early spring
from the leading shoots, plants should be allowed to become
well pot-bound in comparatively small pots during winter.

The pleasing little biennial Stonecrop which forms the
subject of our figure is one of the most charming members
of its genus, from all others of which it is readily distinguished
by its beautiful rosy flowers. In Sedum sempervivoudes,
Fisch., which has already Leen figured at t. 2474 of this
work, and to which S. piloswm is most nearly allied, the
flowers are deep red, and there are several other species 1n
which the petals are purple. But except in S. pilosum we
do not in the genus Sedum find the rich rosy colour which
the petals of our plant possess. In this regard and in their
shape and general facies the flowers of S. pilosum bear a
greater resemblance to those of a Crassula than to those of
a Sedum, though the number of the stamens and_ the
disposition of the leaves prove conclusively that it 1s to
the latter, not the former genus that our. plant must be
referred. A native of the Caucasus, where it affects exposed
localities at heights of from 4,000 to 5,000 feet above

Juty, 1918.

sea-level, S. pilosum is quite hardy in this country when
grown in well-drained, sunny situations in a stony soil.
The plant from which our figure has been prepared is one
which was received at Kew from the Burton Hardy Plant
Company early in 1911. It had been raised, as were other
plants already in cultivation but not yet in flower at Kew
when this plant arrived, from seed sent to England in 1910
by Messrs. Regel & Kesselring of St. Petersburg.

pubescent. Leaves 4-2 in. long, ~,-} in. wide, oblong or

So far as is at present known, the subject of our illustra-
tion, the Umqwashube of the Kaffirs or Red Alder of
European settlers in South Africa, is the only African
representative of the genus Cunonia, the other members of
which, some ten in number, are confined to New Caledonia.
While fairly abundant in the forest tracts of South-Eastern
Africa, where it is a tree reaching a height of some fifty
feet, C. capensis is hardly entitled to be considered a forest
tree, because it is rarely to be met with except on the fringes
of forest tracts. The wood is valuable, being as hard as
boxwood, resistant to fire and durable in water ; it is besides
of a rich red colour and is very handsome when polished.
The scarcity of the tree, however, prevents the extensive
use of the wood. There used to be large plants of C.
capensis in various conservatories in the United Kingdom,
notably a fine example at Syon where it grew well and

Jury, 1913.

flowered every year, and-another at Bicton which throve so
vigorously as to require severe pruning to keep it within
bounds, At Kew it is grown in the Temperate House, but
has never flowered satisfactorily, probably owing to its
need for more direct sunlight than it there enjoys. The
material for our figure was obtained from a specimen in the
Botanic Garden of Trinity College, Dublin, with the history
of which the name of Dr. Harvey, the well-known authority
on the flora of South Africa, is inseparably associated,
though, as Professor Dixon informs us, there is no
particular record connected with the Dublin plant, which
is grown in a cool greenhouse in the usual loam to which
some peat has been added, and flowers every year. The
flowers are fragrant.

Descriprion.— Tree, evergreen, in conservatories 12-15
ft. high, in a wild state up to 50 ft. high. Leaves opposite,
Jong-petioled, unequally pinnate, up to 9 in. long, lateral
leaflets 4 or 6, spathulate-oblong, terminal oblanceolate,
acute at the apex, cuneate and narrowed into the petiolule
at the base, 24-4 in. long, %-14 in. wide, glandular-serrate,
coriaceous, glabrous, dark green and shining above, paler
beneath ; petiolules short or very short; petioles 14-24 in.

the new shoots. Flowers in dense axillary racemes;

green, ovate, deciduous, imbricate, very small. Petals 5,

The Crotalaria here figured, one of the finest and one
of the largest-flowered of the African species of this genus,
is a native of Uganda and British East Africa, and
throughout this area appears to be rather widely spread
and fairly common. It forms in a wild state a large, hand-
some shrub with numerous long racemes of large greenish-
yellow but nevertheless brightly coloured flowers. It is
closely allied to the more familiarly known C. laburnifolia,
Linn., but its larger leaflets are more acute, the peduncle of
its raceme is much longer and stouter and the flowers are
very much larger. ‘The plant has been grown for the first

time in this country in the garden of Mr. Ingham Whitaker
at Pylewell Park, Lymington, by Mr. W. F. Hamilton, by
whom aspray was submitted for identification in November,
1912, followed later by further material which has admitted
of the preparation of our plate. Under greenhouse condi-
tions the species has thriven well and flowered freely under
Mr. Hamilton’s care.

The Periwinkle which forms the subject of our plate is a
native of the Western and Central Mediterranean region
from Portugal to Italy and Algeria, where it is to be met
with in moist and shady places, mostly in hedges and woods.
According to Dr. Schneider it is extremely rarely met with
in cultivation. The plant which yielded the material for
our illustration is one which was presented to Kew by
Canon Ellacombe, in whose garden at Bitton the species has
long been grown. It is a dwarf shrublet of the easiest
cultivation where the climate is sufficiently warm for its
constitution, but it is not so hardy as the two species,
-V. major, Linn., and V. minor, Linn., which are most
commonly met with in English gardens, The plant figured
had been grown in the open air, but as it was thickly
set with flower buds in November, 1912, it was taken up,
potted, and placed in a greenhouse. From then until
February, 1913, it kept up a continuous succession of flowers,

Juy, 1918.

and the species therefore promises to be of value for green-
house decoration during what are the dullest months of the
year. According to Dr. Coutinho a variety bicolor,
characterised by having a white centre to the corolla, has
been met with in Southern Portugal. he species is very
readily increased by means of firm, woody cuttings.

Description.— Undershrub, evergreen and dwarf, with
prostrate leafy branches and ascending flowering twigs.
Leaves ovate, base rounded or shortly cuneate, apex sub-
acute or obtuse, 14-23 in. long, 1-12 in. wide, quite
glabrous; petiole }-1 in. long. Flowers solitary in the

The striking Stanhopea of which a figure is here given
is a native of Colombia, where it was first discovered in the
province of Antioquia and whence it was first imported by
Mr. F. Claes, in whose establishment at Etterheek, Brussels,
it flowered in September, 1909. The plant from which the
material for our illustration was obtained is one that was pre-
sented to the Kew collection by Messrs. Charlesworth & Co.,
Haywards Heath, in 1911. It flowered at Kew in October,
1911, and again in October, 1912. It has thriven well

The attractive Composite here figured is endemic in
Malta, where, according to Rouy, it is met with mainly in
the central portion of the island, more especially in the
gorges of Wied-Baba near Zurrico and of Wied-Mokbel.
For its introduction to collections in this country we are
indebted to Professor G. Henslow, who sent a plant from
Malta to the Cambridge Botanic Garden in 1894. When af
a later date the Cambridge plant was lost, it was replace
by one from the garden of the late Sir Thomas Hanbury at
La Mortola.. From this plant came the material, sent by
Mr. Lynch at the request of Professor Henslow, from rae

informs us, it has thriven well in the Succulent house under
conditions suitable for species of Sempervivum and similar
plants. It is not difficult to grow, and in sandy Joam in not
too Jarge a pot it will flourish for several years. Owing,
however, to the liability of old plants to die it is desirable to
keep a second and younger specimen in reserve. It is
readily propagated by means of cuttings. The fleshy leaves
and the absence of appendages to the involucral bracts
render this species a distinct and well-marked one. But
while there is no question as to this, its generic position has
been disputed ; some authorities, among them Mr. Rouy,
regard it as a Serratula; others, whom we preter to follow,
accept the view of Professor Bertolini and treat it as a
Centaurea. |

The subject of our illustration, which is an endemic
species in the Canaries, is, according to Dr. Schenck, the
most characteristic plant of the Alpine region of Teneriffe,
where it is abundant between 6,000 and 9,000 feet above
sea-level, and is to be met occasionally even at 10,000 feet.
Here it forms a compact globular bushy shrub about five
feet in height, and nearly as much across. Dr. Christ,
in consequence of its peculiarly characteristic nature, speaks
of it as the “ Alpenrose,” or the “ Krummholz of the Peak.

As the synonymy cited above indicates, there has been
considerable diversity of view as regards the generic
position of this plant, though it seems clear that there is no
justification for either of the two rival views which have
found most favour, and that the species cannot be considered
a Spartium or a Genista. There is more to be said in favour
of the view that this endemic species represents a distinct
generic type, but although in habit it is more suggestive
of a Fetama, Mr. Craib considers that, in the present state
of our knowledge, it is preferable to follow Dr. Briquet and
retain the plant in the genus Cytisus. The material from
which our figure has been prepared was sent by Sir F.
Moore from the Royal Botanic Garden, Glasnevin, where it
is grown against a wall. Like other Brooms, that of the
Peak of Teneriffe is a lover of the sun, and though not
hardy in the open ground in most parts of this country,
might well succeed on a sunny wall. At Glasnevin ‘it
flowers in May, and is very striking in its long wands of
creamy white blossom. It should be propagated by seeds.

Description.—Shrub, branches rather stout, erect, striate,
at first loosely clothed with white hairs, soon glabrous.
Leaves 3-foliolate, with petioles 1 in. long; leaflets linear-
lanceolate to narrow-oblanceolate, acute or obtuse, cuneate
at the base, usually about as long as the petiole, pubescent
on both surfaces, Flowers lateral, shortly pedicelled,
pedicels adpressed hairy. Calyx almost 2-lipped, tubular-
campanulate, gibbous above, adpressed-hairy; tube } in.
long; upper lip with 2 short, acute, deltoid teeth; lower
lip somewhat spreading, 3-toothed, the central tooth the

The Grevillea now figured, G. bipinnatifida, R. Br., 1s a
native of rocky localities in the neighbourhood of the Swan
River in Western Australia, and among the many species
of the genus in cultivation in Europe it is one of the most
ornamental, not only on account of the beauty of its flowers,
but also because of the charm of its foliage. The species 1s
perhaps most closely related to G. Gaudichaudi, R. Br.,
and to G. acanthifolia, A. Cunn., both of which are natives
of and endemic to New South Wales, and therefore geogra-
phically widely separated from our plant. Neither of these
eastern species is sO attractive as G. bipinnatifida. The
material for our plate has been derived from a plant
which was raised from seed received at Kew in 1909 from
the Adelaide Botanic Garden. This plant is now a shrub
some three feet high and leafy to the base. The first
flowers appeared in December, 1912.

The pleasing stove plant which is here figured belongs
to the Labiate genus Solenostemon, which is very closely
allied both to Plectranthus. and to Coleus, but is readily
distinguished from these two genera by its subequally two-
lipped calyx, the upper lip being entire, the lower minutely
notched at the tip. Of the seven species known to belong to
the genus, S. Godefroyae is the first to find a place in cultivated
collections. First discovered by Mr. and Mrs. Monteiro
in 1873, about fifteen miles from Ambriz 1m Angola, it
was in the “Flora of Tropical Africa” referred to its
proper genus, but was not distinguished from 4. ocymoides,
Schum. & Thonn. ‘Thirty years later 1t was rediscovered
in the Congo State by Mr. Godefroy-Lebeuf, and was
treated by him in his Catalogue as a distinct species,
though unfortunately Mr. Godefroy-Lebeuf, who at the

same time supplied a figure of the plant, placed it in the
genus Coleus. A plant in flower was sent to Kew in
November, 1903, by Messrs. Sander & Sons, St. Albans, and
in 1911 another plant was supplied to Kew by the Jardin
Colonial, Lacken. From the last mentioned plant, which
has thriven well when grown in an intermediate tempera-
ture along with Begonias, where it forms a shrub two feet
high which flowers freely throughout the winter, was
derived the material on which our figure has been based.

The Dammar which forms the subject of our illustration
is endemic in mixed forest in the Fiji Archipelago, where it
is known as the Dakua, and is abundant in the islands of
Vanua Levu and Viti Levu, though it also occurs, but less
plentifully, in the Islands of Ovalau aud Kaduvu. From
Ovalau some particularly fine individuals have heen re-
ported; one of these hada diameter of five feet ; others had
attained a height of from eighty to a hundred feet, with
sixty feet of clean stem. The bark in A. vitiensis peels off
like that of the Australian gum-trees, the shreds being

serves much the same uses as deal, is employed by the Fijians

used for burning in place of the cocoa-nut oil employed in
the smaller islands. This gum, known as Makadre, burns

obtained. The material for our figure has been supplied
by a plant raised at Kew from seeds presented in 1881 by
Sir J. B. Thurston, then Governor of Fiji. This plant was
grown in the tropical Palm House until 1897 when it was
transferred to the newly constructed Mexican House. Here
it has thriven well and is now a tree twenty-five feet in
height. The female cone depicted was developed in 1911;
male catkins had, however, been borne in previous years.

The Rose here figured, which is one of the most distinct
of the American species, has been described as the South-
Western Prairie Rose owing to its being apparently re-
stricted to the prairie region of Arkansas, northern and
central Texas and the Indian territory. It is well charac-
terised by its very dwarf habit, its running rootstocks and
its fragrant carmine blossoms. It was originally discovered
by Nuttall during his Arkansas visit in 1818-20, but was
not published by Torrey & Gray until twenty years later,
and after it had been met with in Texas by Berlandier,
Drummond and others. The garden history of 2. foliolosa
is somewhat obscure. It was, according to a manuscript list
of the trees and shrubs in cultivation at Kew prepared in
1880 by Sir Joseph Hooker, already in the Kew collection
at that date, but as late as 1890 it was still deemed a rare
plant at Harvard, Massachusetts. The material for our
illustration has been obtained from a plant in the garden of
Canon Ellacombe at Bitton, where it was n flower as late

SepremBer, 1913.

as the end of August, 1912. Asa garden rose Rf. foliolosa
is charming in the bright colouring of its petals and in its
dwarf stature. Owing to its habit of spreading by under-
ground suckers it is easily increased by division. In rich
deep loam, such as it experiences in the Bitton garden, this
species succeeds admirably.

Descriprion.—Shrub of dwarf habit, 1-13 ft. high;
twigs smooth or armed with a few straight slender prickles,
glabrous. Leaves scattered, 2-3 in. long; rachis sparingly
pilose; leaflets 7-9, shortly petiolulate, lanceolate or linear-
oblong, acute, serrulate, glabrous above, sparingly pubescent
beneath, 3-2 in. long, 4-4 in, wide, stipules adnate, linear
or very narrowly oblong, acute or shortly acuminate, finely

The interesting Catasetum now figured was presented to
the Kew Collection by Mr. W. Fox, by whom it had been
found in November, 1911, growing on a dead stump near an
Indian house on the River Igaraparana, a tributary of the
River Putumayo in Peru. It has been grown in a tropical
house under the treatment suitable for other members of
the genus and has thriven well. It flowered for the first
time in March, 1913. Owing to the numerous filiform
appendages on the labellum, C. microglossum may be

regarded as an ally of C. barbatum, Lindl., a species figured
at t. 3514 of this work under the name Myanthus barbatus.
It differs, however, from C. barbatum and from all the other
members of the same group in having a greatly abbreviated
and saccate lip with, as a consequence, the aggregation of
the appendages in a dense mass. The tips of the sensitive
antennae are partially embedded among the filaments of
the lip.

The charming Jris which forms the subject of our illustra-
tion is one for the material of which we are indebted to the
Hon. Mr. N. GC. Rothschild, who has also presented the plant
itself to the Kew Collection. It was obtained in the first
instance, so Mr. Rothschild informs us, from Mersina in
Cilicia. In referring this Jris to I, mellita wt will be ob-
served that Dr. Stapf applies the name. first employed by
Professor Janka to a plant from Thrace in such a way as to
include the /ris from Asia Minor described by Mr. Baker as
I. rubro-marginata, and at the same time yet another plant
which fourteen years ago was introduced by the late Mr.

Serremper, 1913.

Max Leichtlin to European gardens, ostensibly as a native
of Western Persia, under the name J. Straussi7. In connec-
tion with the expression of this more comprehensive view it
may be remarked that Professor Velenovsky, whose local
knowledge is so exhaustive, admits that I. rubro-marginata,
Bak., and J. medlita, Janka, are identical, and that Mr. Dykes,
in his recent authoritative review of the genus, does the
same. The presence of a purple edging to the leaves and
spathes, whence J. rubro-marginata derived its name, is, as
Mr. Dykes has pointed out, an unstable feature. Apart
from this character the Asia Minor plant, judging from
herbarium material, differs from the Thracian form mainly
in having somewhat stouter rhizomes and broader leaves,
with practically no stems. The plant here figured is, then,
a “rubro-marginata” without any trace of the purple
edging. In the specimens of J. Straussii, Leichtl., as
cultivated at Kew, we find the broad leaves of J. rubro-
marginata but a distinct stem. The Kew plants are from
rhizomes communiéated by the late Mr. Leichtlin in 1899,
the year in which the description of J. Straussii first
appeared. Mr. Dykes has stated that more than one species
has been put on the market as I. Straussii ; he even appears
to doubt whether the J. Straussii originally issued by Mr.
Leichtlin came from Sultanabad in Persia. “As to the latter
point it is clear that about 1898 Mr. Leichtlin did receive
from Mr. Strauss an Jris from Sultanabad which he named
Z. Straussii in compliment to its contributor. It is also
certain that Mr. Leichtlin distributed specimens of an Iris
under that name, and it is certain that the description of J.
Straussii in the “ Revue Horticole” for 1899 exactly fits the
plant sent to Kew under the same name in the same year.
The suggestion that the confusion to which Mr. Dykes
alludes was created by Mr. Leichtlin at the outset, is not
borne out by the evidence at our disposal. If such a con-
fusion arose later on, there is no trace of its existence
among the plants sent by Mr. Leichtlin to Kew. So far as
existing knowledge goes, these Thracian, Anatolian and
Persian plants are not more than forms of the same some-
what variable species. Janka originally described J. mellita
as having dull violet or purplish flowers, with a bluish-white
beard. Velenovsky has in one passage termed them violet
or greenish-violet ; in another “ most often violet but some-

times dull violet, rarely yellowish.” The original J. rubro-
marginata had uniformly lurid purple flowers; the J.
Straussii of the ‘‘ Revue Horticole ” had brownish and violet
flowers. In a drawing made at Kew in 1901 of one of the
plants of J. Strausszi communicated by Mr. Leichtlin the
flowers are brownish-violet, the standards being of a clearer
and deeper colour ; the falls and the standards are brownish
at the base with just the mottling shown in the yellow form
from Mersina now figured. The veining of the claws of
the falls and the colouring of the beard also agree, except
that the tips of the hairs of the latter are of a deeper blue.
The original 7. mellita was first collected by Janka in 1871
on dry grassy slopes on T'schiendem Tepe near Philippople
in Bulgaria; it has since then been frequently met with
throughout southern Bulgaria. The original J. rubro-
marginata was described from specimens collected near
Scutari by Mr. W. Barbey of Geneva, but it has since been
sent to Europe from Smyrna. The plants at Kew received
and grown under the name J. Straussii thrive satisfactorily
in well-drained loamy soil in a border on the south side of
a warm building, where they flower annually but do not
ripen seeds.

Descriprion.—Herb, rootstock as thick as the index-
finger or less. Leaves densely tufted, ensiform and more
or less falcate, at flowering time up to 24 in. long, over

The Bladderwort here depicted is one that was first
discovered in 1840 in Brazil by Professor G. Gardner, who
found it growing in moist localities on Mt. Pedra Bonita
near Tejuco in the state of Minas Geraés. It appears to
have been introduced to English gardens some forty years
later, and since then has been fairly common 10 English
collections. The plant has been in continuous cultivation
at Kew for about thirty years, and has during this period
flowered several times, but has never flowered here so satis-
factorily as it does at Cambridge, where 1t grows well in
a tropical house under the conditions suitable for Nepenthes.
The material from which our figure has been prepared was
obtained from a Cambridge pn and was communicated
by Mr. R. I. Lynch. Especial attention has been called to

by Mr. Watson and in “ Flora,” vol. xlvii. n.s., p. 293, t. 14,

the leaves may grow out into bladder-bearing stolons or
may produce from their tips tufts of leaves and stolons and
rhizoids. This phenomenon is not infrequent in the genus
Utricularia, but in U. longifolia it is unusually striking on

This striking Stanhopea is one of the earliest known
species of the genus and was originally described and
figured by Humboldt and Bonpland in 1805, as Epiden-
drum grandiflorum, from specimens collected in shady
woods near Cuenca in Ecuador. Later it was transferred
by Kunth to Anguloa; still later to its true genus, as
S. grandiflora, by the younger Reichenbach. This simple
history has been somewhat obscured owing to the circum-
stance that LindJey had in the meantime applied the name
S. grandiflora to a very different plant, now regarded as
merely a form of the earlier S. eburnea, Lindl., and because
of the fact that Reichenbach reduced to the true S. grandiflora
the Mexican species S. Buchepalus, Lindl., and added to it, as
a variety, the Panama species S. Jenischiana, Kramer. The
confusion thus induced Lindley aggravated by citing the
locality and these synonyms of the Ecuador plant under
one originally stated by him to be a native of Mexico; later

OcroBER, 1913,

he transferred the synonyms from the Ecuador species to
S. insignis, Frost—another error, though one that does not
concern us here. The Jate Mr. Consul Lehmann, whose col-
lections are now at Kew, during a visit to Cuenca was able
to collect there further material of S. grandiflora, Reichb. f.,
and to make in the field a coloured sketch of a single flower ;
this material has enabled Mr. Rolfe, in the “ Orchid Review,”
vol. xx., to disentangle the history of the species. The figure
here given has been prepared froma plant which flowered in
May, 1912, in the collection of Sir F. Crisp at Friar Park,
Henley, who kindly provided the material required. Like
the other species of Stanhopea, the subject of our illustration
thrives well and flowers freely in a warm moist house.
Plants are most conveniently grown in baskets suspended
from the roof, in a mixture of peat fibre and sphagnum
which should be kept moist during the season of growth
and dry whilst the plants are at rest.

Description.—Herb, epiphytic ; pseudobulbs ovoid, sul-
cate, about 2 in. long, I-foliate. Leaves petioled, elliptic
or obovate-elliptic, abruptly acuminate, plicate, 10-12 in.

4—T-flowered, clothed below with ovate-oblong imbricate
sheaths; bracts oblong or lanceolate-oblong, subacute, con-
volute-conduplicate, 13-2 in. long; pedicels 3-1 in. long.

The Rhododendron which we figure is one of the Chinese
species raised by Messrs. J. Veitch & Sons from seed
collected on their behalf by Mr. E. H. Wilson. While the
plants were still young they were referred to R. Davidir,
Franch., another Chinese species, though it was observed
that the leaves in this plant, which are rounded or almost
cordate at the base, differ considerably from those of
R. Davidii which are narrowed to the petiole. Now that
flowers are available it is found that hk. haematocheilum is
easily distinguished from R. Davidu by its much less
elongated inflorescence and by the glabrous, smooth ovary
and style. Its nearest allies appear to be k. Fargesit,
Franch., and R. Sheltonae, Hemsl. & E. H. Wils., though
it differs from both, as it does from R. Fortune, Lindl., by
its pistil, In the expanding flower the corolla is almost
blood-red, in the newly expanded flower it is a rich
carmine which fades gradually with age. From this
striking feature has been taken the name applied to the
Species, which appears to be hardy in the nurseries of

Octosper, 1913.

Messrs. Veitch at Coombe Wood, where it has thriven well
under the conditions suitable for other Chinese Rhododen-
drons. For the material on which our figure has been
based we are indebted to Messrs. Veitch.

The subject of our illustration is a native of Peru
which belongs to a very natural group of species formerly
referred partly to Episcia and partly to Alloplectus, more

recently brought together under the old generic name
Nautilocalyz. The species in question agree with Episcia
as to habit and in general facies, but differ from members of
that genus in having ovules only on the inner surface
of the placental lamellae. From Alloplectus they are
readily distinguished in being herbs and in having a
relatively large corolla-limb. The mussel-shaped anther-
thecae serve to separate them from the closely allied genus
Centrosolenia. The plant from which the material for our
figure has been obtained was presented to Kew by Messrs.
F. Sander & Sons, St. Albans, to whom it had been sent
from Peru by their collector Mr. Forget. It grows freely
under warm greenhouse conditions and forms numerous
stems which flower more or less continuously throughout
the summer, It is easily propagated by means of cuttings;
it also ripens seeds. There are two other species of
Nautilocalyx in cultivation, both readily distinguishable
from NV. pallidus in having yellow flowers and leaves
purple beneath. One of them, NV. Lynchii, has been figured
in this work, at t. 7271, as Alloplectus Lynchii; it has
smooth leaves and has calyx-seements much shorter than
the corolla-tube, and is thus readily distinguished from the
other, V. bullatus, often known as Episcia tesselata, which

has bullate leaves and calyx-segments nearly as long as the
corolla-tube.

Desoriprion.— Herb, branching at the base, stems several,
erect, cylindric, thick and fleshy, shining, shortly pilose, 14 ft.
high, internodes 14-3 in, long. Leaves ovate-lanceolate, —
shortly sharply acuminate, recurved, gradually narrowed
to the base, 6-10 in. long, 23-4 in. wide, margin flat,
crenate-serrate, sparingly ciliate, shining above, pale green,
nearly glabrous, the nerves and veins distinctly sunk,
underneath dull, whitish-green, apparently glabrous, in
reality very finely puberulous, nerves and veins raised; _
lateral nerves about 12-14 on each side; petioles }—} in.
long. Cymes 3-6-flowered ; bracts paired, spreading,

The subject of our plate bears a name which is familiar in
English gardens, where it has fora couple of generations been
erroneously applied to Hydrangea petiolaris, Sieb. & Zuce.,
another and an allied Japanese climbing shrub. There has
never been any very valid excuse for this curious misappre-
hension, because in H. petiolaris the sterile flowers have four
segments, whereas in the sterile flowers of Schizophragma
there is but a single bract. Asa matter of fact, in spite of
the familiar misuse of its name, the true S. hydrangeoides,
now figured, is a comparatively recent introduction to
British gardens and appears to have first blossomed in this
country in 1905 with the late Mr. B. E. Chambers, of
Grayswood, Haslemere. The spray from which our plate
has been prepared came from the garden of Miss E. A.
Willmott at Warley Place, on July 12, 1912, and a few
days later a second spray was received from Sir Edward Fry,
from his garden at Failand House, near Bristol. The plant
at Warley Place grows along with Hydrangea petiolaris on
the wall of one of the garden offices, where the two flower

simultaneously. In wild specimens there is much variation
in the size of the sterile bracts, and that this is nearly as
marked in cultivated examples will be realised when the
cordate bract in the upper right-hand corner of our plate,
which was drawn from Sir E. Fry’s specimen, is compared
with those drawn from Miss Willmott’s spray. The only
other known species of the genus are S. integrifolia, Oliv.,
and S. hypoglauca, Rehder ; both are readily distinguished
from S. hydrangeoides by their larger, entire leaves. S.
hydrangeoides does not flower freely in the British Islands;
probably it requires more sun than our climate usually
affords. The fact that its flowering was reported from
several places in 1912 may well have been the result of the
heat of the previous year. In the Eastern United States,
however, it seems to flower as freely as Hydrangea petiolaris
does with us. It likes a good loamy soil.

Description.—Shrub, deciduous, climbing by means of
aerial roots and attaining the tops of trees up to 40 ft. high;
twigs at first covered with loose down, soon becoming
glabrous. Leaves opposite, exstipulate, membranous, broadly
ovate or nearly orbicular, acute or acuminate, base truncate
or cordate, coarsely dentate, 2-54 in. long, 13-54 in. wide,
dull green above, with short adpressed hairs chiefly on the

The pleasing Streptocarpus which forms the subject of
our plate is very closely allied to the well-known S. Leai,
Lindl., but differs in having the corolla-tube absoluteiy
much shorter and relatively more dilated at the throat.
S. cyaneus was first met with in 1891 by Mr. E. E. Galpin
in wooded kloofs near Barberton, but the specimens on
which the original description was based were collected in
1905 by Mr. J. Burtt Davy, who found them growing on
rocks and tree-trunks in dense shade at Forbes Reef Bush
in Swaziland. The specimen here figured is one of a
number raised from seed collected near Barberton by Mr.
Thorncroft and presented to Kew by Mr. W. E. Ledger
of Wimbledon. ‘The flowers in this stock of seedlings vary
in colour from pale lavender or blue to rose-pink or rosy
mauve; in the latter case the two upper lobes often shade
into blue in the central area; the three lower lobes have a
few streaks of red, and a blotch of yellow occurs within the

corolla-tube. The cultural treatment most suitable to
S. Rexit appears to be that under which S. cyaneus grows
best and thrives most satisfactorily. Like the other species
and varieties of Streptocarpus in cultivation, this one is
shortlived, and like them it might almost be termed a
biennial, at all events most of the forms are at their best
in their second year. Mr. Brown ‘is of opinion that
individual flowers in this species cannot be self-fertilised,
the anthers being so closely pressed together that although
open on their opposed faces no pollen can be shed until
they are separated, and as the anthers are closely pressed
against the style a little below the stigma, it is difficult to
conceive that any pollen should reach the stigma without
insect aid.

Descriprion.—Herb, perennial, but for cultural purposes
sub-biennial, stemless. Leaves many, radical, prostrate, sub-
sessile or narrowed to a petiole, narrowly elongate-oblong
or oblong-lanceolate, obtuse, crenate, slightly bullately
rugose, 25-84 in. long, 2-2 in. wide, roughly pubescent
on both sides, green above, paler beneath; petiole 0-2 in.
long. Scapes erect, 3-6 in. long, almost always 2-flowered,
pubescent like the pedicels and the flowers outside with
simple and gland-tipped spreading hairs; pedicels 4-2 in.
long. Sepals % in. long, linear, obtuse or subacute. Corolla
narrowly funnel-shaped ; tube 2-1} in. long, white with
a yellow streak within; limb oblique, unequally 5-lobed ;
lobes 4-1 in, long, under 3 in. wide, suborbicular or orbi-
cular-oblong, variable in colour, blue or rose-mauve or
Ag with the centre of the upper lobes blue and of
the lower lobes streaked with red. Stamens included ;
filaments curved upwards, white dotted above with golden-
brown glands; anthers closely touching, adpressed to the

The handsome Aroid of which a figure is here given is
a native of the Philippines, where it was first met with
some fifteen years ago by Mr. Loher in the province of
Benquet in the island of Luzon. It was met with again
by Mr. Micholitz, also in Luzon, when collecting there on
behalf of Messrs. Sander & Sons, St. Albans, by whom it
was introduced to cultivation about three years ago. Very
nearly allied to the familiar Alocasia Sanderiana, Bull, this
new species differs therefrom in having smaller leaves,
less deeply lobed at the margins, with a deeper and very
different shade of green and without silvery borders to
the almost straight (not distinctly curved) primary lateral
veins. In our plant, too, the leaves are very rarely peltate,
and when they are peltate they are so to a much less degree
than is the case in A. Sanderiana. The spadix, too, is here
nearly as long as the spathe, and its appendix is longer
than the floriferous portion, whereas in A. Sanderiana the

November, 1913.

spadix is much shorter than the spathe and the appendix is
shorter than the flower-bearing part. Evergreen in habit,
A. Micholitziana is easily grown, and thrives well in a
shady position ina hot moist stove. It requires an open
compost, rich in humus, with abundant moisture at the
root during the season of growth. <A partial rest should
be given during the winter months, the plant being kept
somewhat drier at the root, and only sufficient water being
supplied to enable it to retain its leaves. Propagation is
readily effected by dividing the stem into sections, potting
these up and plunging the pots in a moist case in brisk
bottom heat until new growths are obtained.

Descriprion.—Jerb ; stock perennial, caulescent, erect,
about 14 ft. in height, 1-14 in. thick. Leaves sagittate or
slightly peltate-sagittate, sinuately lobed, above strikingly
dark green with paler midrib and main-nerves, beneath
pale green, the anterior lobe 4-10 in. long, 24-54 in. wide,

portion. Ovary globose; style very short; stigma sub-
capitate. ,

The neat little Rhododendron which forms the subject
of our illustration is a native of the moorland tracts and
rocky slopes characteristic of the loftier passes leading
across the Eastern Himalaya into Tibet, within a few miles
of the summits of which it reaches its uppermost limit.
Here the brilliant red-purple flowers render the species a
charming object, and after hot sunshine the air is filled with
the heavy aroma due to a copious resinous secretion which
testifies to the comparatively dry climate it enjoys. In
its late flowering, which takes place in June and July, and
in its early fruiting, which occurs in October, &. setosum
bears witness to the brief summer of the elevated regions
it affects. The Bhoteas of Sikkim and of Tibet, who
know the plant as “Tsallu,” regard it and £&. anthopogon,
Wall., for which their name is “Palu,” as largely con-

tributing by their strongly resinous scent to the headaches
and the feeling of oppression which not infrequently
attend the crossing of the lofty passes they inhabit, and
there is no doubt that the aroma they emit is too heavy
and powerful to be wholly agreeable. From its dwarf
habit and its slow growth R. setosum is best adapted to
places like the Rock-garden where it is relieved from
competition with stronger-growing plants. It needs a
damp peaty soil. It has never been common in cultivation
in Great Britain, and appears here to be short-lived. At
present it is quite rare in collections; the material for
our figure was obtained from a specimen in the garden of
Sir E. G. Loder, at Leonardslee, Horsham. Like many
high Alpine species it would doubtless succeed better where
there is a well-defined winter and a regular snowfall than

it does under our indeterminate seasons and late spring
frosts,

Among the numerous New Zealand species which have
been the fruits of the journey of Capt. A. A. Dorrien-Smith
to that Dominion one of the finest is the Senecio which forms
the subject of our illustration. According to Mr. Cheese-
man, S. Kirkii is common in the North Island of New
Zealand, where it is endemic, from sea-level to an elevation
of 2,500 feet from the North Cape to Wellington. The
corymbs, according to Mr. Kirk, are sometimes highly
compound and as much as three feet across. At times too the
species is epiphytic on the distorted trunks of Rata and
then may form a dome-shaped crown, twelve to twenty
feet in diameter, with the foliage completely hidden by the
snow-white flowers. Such specimens in the distance are
remarkable and conspicuous objects. The shape of the
leaves and the large corymbs of fine white flowers enable
the species to be readily distinguished from the other

Senecios of New Zealand. The material for our plate has
been supplied by Mr. T. A. Dorrien-Smith from his garden at
Tresco Abbey, Isles of Scilly, where the plant thrives well
in good soil. It has to be noted that while the bracts in
the specimens sent for the purpose were oblanceolate and
toothed, as shown in our figure, the corresponding bracts in
the majority of the wild specimens in the herbarium at

Kew are ligulate and entire. 3

The genus Coriaria to which the subject of our illustra-
tion belongs is so singular as to justify its being regarded
as the type of a distinct natural family occupying a very
isolated “position. By Bentham and, Hooker this family
has been placed at the end of the Discifloral families with a
note that it seems related to some of the Thalamifloral ones
and has points in common with the Phytolaccaceae among
the Incompletae. By Engler it has been included in the

November, 1913.

Sapindales on account of the pendulous ovules with a dorsal
(abaxial) raphe. The suggestion in Hooker's edition of
Le Maout and Decaisne’s “System,” that the affinities of
Coriaria are with the Malpighiaceae and other families
of the Geraniales seems, however, preferable to either of the
others. The fruit of Coriaria is peculiar in consisting of
achenes attached by their inner angles to a slender pro-
longation of the torus and surrounded by a pulpy mass
composed of the five much enlarged petals. C. terminalis
may be distinguished from the other species of the genus
by the terminal inflorescence, below which two axillary
leafy shoots are commonly produced. These are dorsi-
ventral, the decussate leaves being brought into a spuriously
distichous position by the twisting of the consecutive inter-
nodes. An easily cultivated undershrub which grows well
in any good loamy soil, C. terminalis is particularly to be
recommended for gardens where the soil is calcareous. The
only disadvantage to be contended with is the susceptibility
of its flower to damage by spring frosts. In the garden of
Canon Ellacombe at Bitton, whence came the material from
which our figure has been prepared, this and other species
thrive vigorously. The seeds of C. terminalis germinate
readily ; the plant can also be propagated by cuttings.

Descriprion.— Undershrub, perennial, 1-4 ft. high,
sparingly branched ; twigs arcuately ascending, 4-angled,
glandular-ciliate, reddish. Leaves opposite, spuriously dis-
tichous through the twisting of successive internodes, wide
ovate, shortly acutely cuspidate, base subcordate ; those of

short. acemes terminal, many-flowered, 5}-6 in. long,
reddish upwards; rachis more or less reddish, shortly
rather closely glandular-pubescent; pedicels glandular-
pubescent, 3-4 in. long; in fruit elongated and }-}in. long,

late, base rounded, ;},—} in. long, about 7/5 in. wide, greenish

The interesting Gesnerad which is here figured is a
native of Siam, where it grows on rocks by streams on
Mount Doi Sutep, near Chiengmai, at about 1,800 feet
above the level of the sea. From this locality seeds were
sent to Kew by Dr. A. F. G. Kerr in 1912; the plants
raised from this consignment flowered in a tropical house
in March, 1913, and provided the material from which our
illustration has been prepared. The species had been
already described by Mr. Craib from herbarium specimens
communicated by Dr. Kerr from the same locality, and had
by him been referred to the genus Streptocarpus, based by
Lindley upon a South African plant; in spite, of the
remarkable extension of range of the genus which this
decision implies, it seems clear that, if a conclusion can be
based upon essential agreement as regards floral and fruit

Novemser, 1913.

structure, the only alternative to the treatment here adopted
must be the recognition of a new Asiatic genus repeating
the reproductive organs of Streptocarpus and separated
therefrom by a somewhat intangible difference in the
morphology of the vegetative organs. Until the stem
develops the leaves are clothed with silky grey hairs.
The. racemose cymes gradually elongate and ultimately
attain a length of ten or twelve inches, so that a plant
continues to bear flowers in succession for two or three
months. Under the conditions suitable for the African
species of the genus, S. orientalis thrives well and produces.
when in flower an elegant effect. It may be propagated
by seed, which it ripens freely.

The graceful Palm of which a figure is here given is a
native of Colombia and is most nearly allied to Morenia
Poeppigiana, Mart., a native of Peru, which differs in
having broader sigmoid leaflets and alternately longer and
shorter filaments. The genus Morenia includes some six
species, all Andine. It is very closely related to the genus
Chamaedorea, Willd., but is readily distinguished in having
a three-toothed in place of an annular or patelliform calyx
in the male flower., One of the species, M. fragrans,
Ruiz & Pav., has already been figured at t. 5492 of this
work ; this species, owing to its specific name, has at times
been confused with the very different Chamaedorea fragrans,
Mart., a palm with bilobate leaves. Two other species of
Morenia, M. corallocarpa, Hort., and M. Lindeniana, Wendl.,
have also been in cultivation ; a sixth species, M. integrifolia,
Trail, distinguished from the others by its simply forked
leaves, is not yet known in collections. ‘The Kew plant of

The Genista here figured has long been a favourite garden
shrub in southern England. Though named G. hispanica,
it is not confined to the Iberian peninsula, but extends from
Portugal to Liguria in North-Western Italy. Its nearest
allies are G. gibraltarica, DC., and G. decipens, Spach ; from
the former it is distinguished by the shorter and denser

DrcemBer, 1918,

inflorescence, from the latter by the subequal petals. G.
hispanica thrives best in a moderate, rather than rich soil,
and in a sunny position, and is an admirable plant for the -
Rock Garden, or a sunny terrace only suited for dwarf
plants. Few shrubs, even in May, can produce a more
brilliant display. In shady positions or too rich a soil,
our plant makes soft, sappy growths which do not flower
freely and are apt to be winter-killed. It is increased by
August cuttings under a cloche, or by seeds. The material
for our plate came from a plant cultivated out of doors at Kew.

The almost pygmy Rhododendron here figured is one
that occurs on grass lands on the mountains of Szechuan in
Western China at elevations of from 10,000 to 15,000 ft.,
where it was collected by Mr. E. H. Wilson on behalf of
Messrs. J. Veitch & Sons. It had, however, already been
met with by French travellers and was first described from
their specimens. The plant from which our figure was
made was obtained from Messrs. Veitch in 1910, and although
then eight years old was still only some ten inches in height.
It is very closely allied to another Chinese species, 4.
intricatum, Franch., of which a figure has been given at
t. 8163 of this work. There are, however, several differ-
ences which serve to separate the two species, and of these
the more obvious are the longer calyx-lobes and the
further exserted anthers and stigma of /. nigropunctatum.
Being one of the dwarfest and neatest of Rhododendrons,
R. nigropunctatum is a charming plant for a moist nook
in the Rock Garden. It requires a peaty sandy soil, and
can be propagated by means of cuttings placed in gentle
heat in August.

The subject of our illustration is a powerful woody ever-
ereen climber which has been in cultivation in the
‘Temperate House at Kew for over a quarter of a century,
and has now attained large dimensions. The seed from
which it was raised came from the Richmond River in New
South Wales, and when for the first time it flowered in
1904 it was, from its flowers alone, described as a new
Wistaria. When fruits became available it was found to
be a’ member of the Brachypterum: section of Derrts, and to

belong to the species which has been accepted by most
authors dealing with the vegetation of Australia as
D. scandens. But while this is the case it is certainly
quite different from the irue D. scandens of India and Indo-
China, and in Australia, where it is met with as a littoral
species from Clarence River in New South Wales to the
extreme north of Queensland and is known as the Climbing
Derris or the Fish-poison Pod, it is the representative
of D. scandens. This south-eastern representative of
D. scandens is not, however, confined to Australia; it
extends beyond the Torres Straits northwards to New
Guinea, and it was upon New Guinea specimens that its
claim to specific rank was first established. The material
for our plate has been obtained from the Kew plant which
has in most years since 1904 produced a few inflorescences.
This shyness in flowering, probably due to an insufficiency
of strong sunshine, militates against the horticultural value
of the species in this country, though doubtless under tropical
conditions it would provea rival to its near ally, D. scandens,
which when loaded with its racemes of rather smaller white
flower is a remarkably striking object. D. oligosperma,
like D. scandens, is a species very easily grown, being the
reverse of fastidious as regards soil, and being readily
propagated from cuttings of the ripened wood when seed
is not available.

long, at the base under 2 in. thick; twigs terete, at first

The attractive Orchid here figured was first introduced
from the Netherlands East Indies by Messrs. Linden of
Brussels, with whom it flowered in June, 1890, when it was
described and figured in Lindenia ; it was named in compli-
ment to the late Dr. Masters, then editor of the Gardeners’
Chronicle. The exact habitat of C. Mastersianum has not
been recorded. It is very distinct from the majority of the
cultivated species of Cirrhopetalum, and while it is in some
respects comparable with C. gamosepalum, Griff., it is quite
different in colour, and has the ciliae of the petals and of
the dorsal sepal very minute. The plant from which our
‘llustration has been prepared is one which was received at
Kew from the Royal Botanic Garden, Glasnevin, 1n 1903.
C. Mastersianum 1s a species which 1s very easily grown ;

it thrives well in a mixture of equal parts of peat, osmunda
fibre and sphagnum, in a basket suspended in a shady

‘tion near the glass of a moist tropical house. It is
i i eriod of rest,

peculiar among its congeners in requiring NO per
and it possesses the unusual habit of flowering at intervals

throughout the year without deteriorating in vigour.
