ECHINOCACTUS RHODOPHTHALMUS.
Red-eyed Echinocactus.
Nat. Ord. Cacte®.—IcosanpRIA MONOGYNIA.
Gen. Char. (Vide supra, Tas. 4124.)
Ecurtnocactus rhodophthalmus ; solitarius subelatus conico-columnaris profunde
8—9-sulcatus, costis obtusis crenato-tuberculatis tuberculis compressis sub-
hemisphericis, areolis obsolete lanatis, aculeis subnovem validis rectis pur-
pureo-fuscis demum pallidis, centrali subduplo majore, calycis tubo obconico
squamoso inermi squamis sepalisve ovatis albomarginatis, petalis spathulatis
roseis basi intense rubris.
Received from Mr. Staines, who procured it from the neigh-
bourhood of San Luis Potosi, Mexico, and we do not find the
description of any species to correspond with it. In its flourishing
state it is exceedingly handsome, the deep red of the base of
the petals forming a ring, as it were, round the densely-clustered
stamens and bright yellow rays of the stigma, adding much to
the beauty of the blossom. It flowers with us in August.
Descr. Our plants are from four to five inches high, sub-
columnar, but tapering upwards almost from the base, deeply
cut into about eight or nine furrows, the ridges obtuse, but formed
into lobes or tubercles by transverse lines ; the tubercles are sub-
hemispherical but compressed ; the areo/e furnished with obscure
wool : the spines about nine, strong, straight, tapering, flattened,
at first deep purple, afterwards pale and almost colourless, length
from three-quarters of an inch to an inch, mostly spreading, but
the central one, which is much the longest and strongest, stands
forward. The flowers are produced from the summit of the
plant, large, handsome. The calya-tube (or green portion) about
an inch long, obconical, quite destitute of spines or sete, but
with the scales or sepals ovate, brown with pale margins, gradually
passing into the long, linear-spathulate, acute, spreading, bright
rose-coloured petals, which have a dark red almost crimson spot
at the base, forming a radiating circle around the column of
stamens and style. Stamens numerous, very compact : filaments

white, slender: style as long as the stamens : stigma of nine or
ten spreading, bright yellow rays, covering the anthers. W./. H.
Curr. At Tab. 4417 we have said that Cactee are almost in-
different as to the kind of soil they are grown in, provided it is not
retentive of moisture. The present very pretty species will thrive
in a mixture of light loam and leaf-mould, containing a small
quantity of lime-rubbish nodules ; the latter bemg for the pur-
pose of keeping the mould from becoming close and compact,
a condition not suitable to the soft and tender roots of the plant.
If cultivated in a pot, it must be well drained; the pot being
nearly half filled with broken potsherds, and the upper layer so
placed as to cover the interstices, in order to prevent the mould
from mixing with the drainage. During winter, Mexican Cactee
do not require much artificial heat : several species are, indeed,
known to bear with impunity a few degrees of frost. Where
they can be cultivated by themselves, we recommend that the
plants and atmosphere of the house should be kept in a dry
state during winter, artificial heat being given only during a
long continuance of damp cold weather or in severe frost ; but
at no time during winter needs the temperature of the house to
exceed 50° at night. In sunny days in spring the house should
be kept close, m order that the plants may receive the full
benefit of the heat of the sun’s rays. As the summer-heat
increases air should be admitted, and occasionally the plants
should be freely watered, and in hot weather daily syringed
over-head. J. 8.

Under the name of Plumbago Larpente this (when well culti-
vated) really lovely plant, has among horticulturists been for the
last two years a subject of much controversy, as regards its
merits as a border flower. This will be alluded to by Mr. Smith
under the head of “Culture.”’ It was introduced to our country
by Lady Larpent, from China, and we perform no enviable
duty in restoring the original specific name (given to it so
long ago as 1831); for we know no lady who has deserved
better of botany and horticulture than Lady Larpent. Her —
garden, at Rochampton, was long distinguished by high cultivation _
and the rarity and beauty of the plants. |
JANUARY Is7, 1850, ae B 2
.
The species inhabits the vicinity of Pekin. We possess an
original specimen from Bunge gathered there, and another from
Mr. Fortune (his 7. 33). We could have wished Boissier had
retained Bunge’s generic name, Ceratostigma, founded on this
species, deriving that name from the minute ramifications of
the stigmas resembling horns, while in the original Valoradia
(established by Hochstetter in 1842) the glands are entirely
sessile. On such grounds we should have to sacrifice a multi-
tude of existing names.
Descr. Foot perennial. Stem herbaceous, varying from six
inches to a foot and a half high, flexuose, angled, and slightly
setose, red, much and densely branched; éranches upright.
Leaves alternate, spreading, obovate, penninerved, obtuse, at-
tenuated at the base, the lower ones almost petioled : the upper
_ ones smaller and quite sessile, all ciliated. Flowers collected
several together, into bracteated sessile, axillary or terminal
heads. Bracteas scariose, tinged with red, cuspidate, ciliated
along the back and at the margin. Calyz longer than the bracts,
slender, tubular, glabrous, furrowed, terminated by five, subu-
late, appressed ¢eeth. Corolla hypocrateriform : the éwbe longer
than the calyx: the Zimb bright purple-blue: the Ziméd regular,
cut to its base into five heart-shaped, spreading /oées, slightly
plaited and minutely toothed. Stamens monadelphous at the
base. Anthers linear, exserted. Ovary oblong. Style gla-
brous, shorter than the stamens. Stigmas five, linear, beset on
on the upper side with prominent clavate or slightly stipitate
glands. W.J. H.
Cur. Although this plant is of but recent introduction, yet
its rapid increase by cuttings has made it already very common
in the gardens of this country. Owing to some circum-
stances connected with its introduction and dissemination, its
cultivation and its merits as an ornamental flowering plant have
been the subject of much discussion with cultivators, perhaps
more than it deserves; for although it recommends itself to
notice by its pretty blue flowers, yet, considering its relationship
and the conditions under which it flourishes in its native country,
we do not think it will give satisfaction as an ornamental plant
to the generality of cultivators. We learn that it is a native of
China, and has been observed ‘as far north as Pekin ; but that the
plant was found in a wild state on the city walls of Shanghae,
“growing out of the stone-work,” and “on the raised ramparts,”
‘where it is said to be very ornamental. We naturally pre-
sume that a stone wall built by the hand of man is not its
original place of growth ; but as it has there become naturalized,
we may infer that its natural habitat is in dry rocky places
Subject to great summer heat, and enduring a considerable de-
gree of cold in winter; for at Shanghae, during the summer
months, the thermometer ranges from 100° to 110°, and falls in
winter sometimes as low as 13°; a degree of cold not much less
than that of many of our winters. This being the first year of
its general cultivation here, it is, as might be expected, praised
by some and called “ worthless” by others; which no doubt
arises from the different conditions and local influences under
which the plants have been placed by cultivators. ‘These condi-
tions, probably, all differ more or less from those which cause it
to become an ornamental plant in its native country, and are
such as we cannot well supply, especially the principal element,
viz., solar heat of a longer duration and a greater degree than our
climate affords. With respect to the degree of cold it will bear,
we have observed that it is injured by a few degrees of frost.
Although it may live in the open ground in moderate winters, in
the character of an herbaceous perennial, yet our protracted cold
weather in spring will retard its growth, and thus, with a defi-
ciency of heat in summer, it will make but little progress. With
such views we consider it best to treat it as a tender plant,
keeping it under protection during winter. If intended for the
flower-border, the young plants should be placed in a warm pit
or frame early in the spring, so as to have them in a forward
state by the end of May; if rfjuired for an ornamental plant in
the greenhouse, it may be potted in a mixture of peat-soil and
vegetable mould, mixed with siftings of lime-rubbish, the pot
bemg well drained, so that any excess of water will pass off
freely. J. 8S. :

Native of New Zealand, where it was discovered, in 1769, by
Sir Joseph Banks, during the voyage of the illustrious Cook.
“Tt inhabits,’ says Mr. Allan Cunningham (by whom it was
introduced to the Royal Gardens of Kew), “usually the rocky
sea-coast and shores of the Bay of Islands, where it is called
by the natives Pohutu-Kawa, and is readily distinguished
among other plants by the brilliancy and abundance of its
flowers, enlivening the shores of the northern island with its
blossoms in December. With us in the greenhouse it has
attained the height of six feet, and attracted attention by its
copious compact, but spreading ramification, and the abundance
and beauty of its evergreen foliage. Its blossoming this year
(for the first time) was probably encouraged by planting it out,
by way of experiment, in the spring, in a sheltered part of the
woods of the Pleasure-ground, in a soil of rich vegetable leaf-
mould. During the summer, almost every branchlet was termi-
nated by the vivid scarlet blossoms, and it became a conspicuous
object at a distance. Already, however, (December 1849) the
frosts have damaged the foliage, and, except those from the lofty
mountains, we dare not hope that any of the New Zealand trees
or shrubs will bear our inland winters in Great Britain.
Descr. In its native country it forms an “ ordinary-sized ¢ree,
JANUARY Ist, 1850.
the wood hard, close-grained, and heavy, equally valuable for
ship-building and implements of husbandry.” The younger
branches green and downy. Leaves opposite, on very short
thick petioles, elliptical and often obtuse, but varying to ovato-
lanceolate, or even lanceolate and acute, coriaceous, under a
lens minutely reticulated and dotted, dark green and glabrous
above, pale, whitish or ash-colour, and downy or tomentosé
beneath. Corymés terminal, very tomentose: pedicels bearing
two or three sessile fowers articulated upon them. Ovary or
calyzx-tube between cylindrical and turbinate, woolly, crowned
by the five, spreading, ovate calyx-lobes. Petals yellow, minute.
Stamens copious. Filaments very long, at first beautifully invo-
lute, at length erect, bright red. S%yle shorter than the
stamens. W. J. H.
Cur. This beautiful Metrosideros is analogous in its manner
of growth to the species figured at t.4471. In its native country
it is described as making its first appearance on other trees, as an
epiphyte. By its strong and rapid growth it soon envelopes the
parent tree, its woody roots descending till they reach the
ground, and there spreading to a great extent, while the main
roots, by their numbers and interlacings, ultimately become so
combined that they form a trunk of a singular appearance and
sometimes of an immense size. The original tree dies, and its
decaying trunk becomes food for the parasite ; the latter in this
respect resembling the fig-trees of the tropics or the ivy of this
country. It is also said to form a tree without the aid of others.
With us it grows luxuriantly if planted in light loam and
kept in a cool greenhouse, and forms a handsome evergreen bush.
The figure here represented was made from an individual that
had become too large for our greenhouse accommodation. As it
afforded the opportunity of testing the degree of cold it would
bear, a sheltered situation amongst trees was selected, where it
was planted in May 1849. During the summer it flowered
profusely, presenting a very striking appearance for an out-door
shrub, and continued to flourish till the first frosts; but we
observe with regret, that this fine shrub will not live in the open
air where the thermometer falls a few degrees below the freezing
point. It is a plant of free growth, and is readily propagated
by cuttings. J.8.

Swertra corymbosa. Wight, MS. in Herb. Hook.
Ophelia corymbosa of Grisebach was first described from
Nilgherry* specimens communicated to us many years ago by
Dr. Wight, under the MS. name of Swertia corymbosa. Seeds
of the plant have been recently sent to the Royal Gardens from
the same country by Dr. Schmidt, and they flowered in a cool
greenhouse in August 1849. Being only an annual, they
would probably have succeeded quite as well in the open aur.
The plant is pretty, and, though not showy, will probably answer
well for bedding out, as it continues long in blossom.
Descr. Root small, annual. Stem erect, a foot high, four-
angled, slightly branched below ; above, every pair of leaves

bears opposite Jranches, which become corymbose at the ex-
tremity. Leaves obovato-spathulate, slightly scabrous at the
margin, the lower ones very obtuse, upper ones almost obovate
and acute. Corymbs terminal ; bracts, or uppermost leaves, often
whorled and then bearing a fascicle of pedicels. Calyx of five,
spreading, narrow, almost subulate sepa/s, shorter than the corolla.
Corolla pale purple with a white eye, rotate, deeply cut into four
spreading broadly obovate, veined segments, at the base of each
of which is a nectariferous cavity, partially closed with a vein
and a tuft of hairs. Stamens four: filaments erect, shorter than
the pistil. Ovary ovate, acuminate : style scarcely any: stigmas
two, short, obtuse, recurved. W. J. H.
Cunr. A tender annual, of slender habit, possessing more
interest for the botanist than as an object of show for the cul-
tivator; and as it does not ripen its seeds freely, it may be
expected to be a plant of not very frequent occurrence. Its
seeds should be sown in the spring, in pots filled with light peat
soil, and as they are small'a slight pressure on the surface will
suffice, no covering of mould being necessary. The pot should
be placed in a warm pit or on a shelf near the glass in the stove,
keeping it in an equable, moderately moist state, and shaded from
the sun in the middle of the day. In watering, a fine rose
water-pot must be used, so as not to disturb the seeds or the
surface of the mould. In some cases like this, it is advisable to set
the seed-pots in pans of water, the water rising to the surface of
the mould by capillary attraction ; but in adopting this method,
care must be taken that the mould does not become saturated,
which it is very apt to do while there are no roots to draw off

they should be thinned out and the pots removed to a cooler
and more airy situation, preparatory to their removal to the
greenhouse, where they will flower during the summer. J. 8.

Notwithstanding certain discrepancies between this plant and
the figure of Ovalis elegans given by Humboldt, above quoted,
I have every reason to believe it to be the same; allowance being
made for that figure being executed from dried specimens. Some
differences also are observable between the figure and descrip-
tion, for whereas the leaves are represented as hairy, the specific
character speaks of them as glabrous. A more important differ-
efice is in the uniformly slightly dilated filaments of the stamens
in Humboldt’s figure, whereas the stamens of our plant exhibit
the long stamens as furnished with a broad scale on the filament,
the shorter ones subulate and naked; but this character is found
to vary extremely in other flowers, and the filaments are even
sometimes as uniformly subulate as in Humboldt’s figure. The
species inhabits the Andes of Loxa in Columbia, bordering on
Peru, at an elevation of nearly 7,000 feet above the level of the
sea. It was there detected by Humboldt, and it was thence
sent by Mr. Wm. Lobb to Mr. Veitch, from whom our specimens
were received. It appears to be quite hardy ; and continuing,
JANUARY lst, 1850.
as it does, flowering through the summer and autumn, it will
probably make a good plant for bedding out. It is difficult to
say which of the two varieties is the best. The flowers of var. a.
are the largest, but the palest coloured: var. 8. has the smaller
but deepest coloured blossom. Whether the purple underside
of the leaf is peculiar to a. or occasionally common to both, I
cannot say.
Dezscr. Roofs, we believe, tuberous. Petioles a span and
more long, rising directly from the root and bearing three
deltoid or subrhomboid /eaflets, radiating as it were from a centre,
glabrous, having obtuse angles, generally purple beneath in a, pale
green beneath in 8. Scapes longer than the petioles, glabrous,
terminated by an umbel of from six to nine or ten handsome
showy flowers. Pedicels at first deflexed, at length, in flower,
erect or spreading. Sepails five, erect, appressed, lanceolate,
somewhat mucronato-acuminate, bearing at the apex four slender,
linear, orange-coloured glands, which unite into one at the very
apex. Petals broad-oval, unguiculate, spreading. The entire
corolla is of a purple colour, more or less deep, and varying a
little in size: in the centre is an intensely dark purple eye.
Stamens 10: filaments glabrous, monadelphous below ; the five
shorter ones naked, the five longer ones generally with a distinct
large scale, but which is more or less obsolete in different flowers.
Styles five, longer than the longest stamens, pubescent: stigmas
dilated and umbilicated. W.J. H.
Curr. This pretty plant represents a form common to a large
groupe of a very extensive genus, characterized as perennial plants
having tuberous roots. The present species, being one of that
groupe, and coming from the elevated region of Loxa, may be
expected to prove hardy, especially if planted in a warm border,
the precaution being taken to cover the border with a layer of
dry leaves, fern, or other such light material, that will act as a
non-conductor of frost. It is necessary, however, to be careful
that such covering does not remain on too long, for it is apt to
stimulate the tubers into premature growth. In cultivating this
plant in pots, a mixture of light sandy loam and leaf-mould will
be found to suit it. The tubers should be potted after the
leaves decay in the autumn, and the pots placed in a cold frame
and kept rather dry during winter. When they begin to grow,
air must be freely given, and the supply of water mcreased in
accordance with ‘their advancing growth. No shading is re-
quired, as the flowers of most of the ‘species only open under
the full influence of the sun. J. 8.

Specimens of this charming annual, rivalling the Bartonia
aurea (from which no doubt it derives its specific name), were
obligingly communicated to us, through Mr. G. Charlwood, of
Covent Garden, by Mr. Booth of the Floetbeck Nursery, Ham-
burg, under the name of Ewenida bartonioides, accompanied by
a very faithful description. It bears the open air like the Bar-
tonia, is admirably suited for a border plant, and we trust that
seeds of it will soon be, if they are not already, in the market.
Dr. Walpers had perceived the close affinity of this with another
plant, our Microsperma lobata, given in the ‘Icones Plantarum
Rar.,’ IIT. tab. 234, and he very properly united it with that genus,
of which it is nevertheless a very distinct and far more beautiful
and showy species. It flowers through the summer months.
Dzscr. An herbaceous annual. Stems about a foot long,
flexuose, succulent, subtranslucent, hispid. eaves hispido-
pubescent, on longish slender petioles, ovate, acute, lobed and
serrated. Peduncles elongated, single-flowered, terminating the

ordinary branches, or short lateral branches, or the flowers may
be said to be in a lax, leafy panicle. Calya-tube adherent with
the ovary, turbinate, very hispid, crowned by five lanceolate
acuminate lobes, twice as long as the tube. Petals twice as
long as the calyx-lobes, ovate or rather obovate, acute, obscurely
serrated, sulphur-yellow, paler, almost white, beneath.. Stamens
arranged in two series and in five fascicles; each fascicle mona-
delphous at the base, and attached to the base of a petal : fi/a-
ments very long. Style as long as the stamens: stigma entire,
but with five longitudinal furrows. W. J. H.
Cur. Our acquaintance with this plant is limited ; the only spe-
cimen we have seen came to the Royal Gardens in flower from
Hamburg. It appears to be an annual, and closely allied in habit
to Bartonia; but we fear it will not succeed out of doors as a
summer border plant, on account of its soft, succulent nature,
which makes it liable to injuries by heavy rain and wind. We
therefore consider it best to treat it as a tender annual, sowing the
seeds in a frame, and, when the plants have sufficient strength,
plant them singly into pots, using a mixture of light loam and
leaf-mould or sandy peat. The pots must be properly drained, and
care taken not to over-water in damp weather, and to admit
plenty of air, so as to keep the plants from becoming weak and
drawn up. As they increase in size they will require to be
shifted into larger pots, and when they begin to show flower
they should be removed into the greenhouse. J. S.

A genus (the origin of whose name is unexplained) estab-
lished by Blume upon a Java plant, detected in the woods
of the mountain: of Salak in Java. Introduced, we believe, by
Messrs. Loddiges, before 1844, Some years previously, another
species of the genus was sent from Ceylon, the A. dicolor
of Lindl. in Bot. Reg. t.1730. 'The present species is much
the handsomest of the two, with larger flowers, beautifully veined
with purplish-red and yellow, and altogether a very striking
plant. It flowered at Kew very finely in July 1849.
Descr. Pseudo-bulbs elongated, cylindrical, jointed, when
young clothed with large furrowed scales, and terminated by
two or three ovato-lanceolate, rather membranaceous, striated
leaves. From the base of the pseudo-bulb the short, thick,
bracteated scape rises, shorter than the rest of the plant, and
bearing about six or eight large handsome flowers, of a yellow
colour, tinged and streaked with purplish-red. The pefa/s and
sepals are somewhat triangular-ovate, so placed that the entire
flower is somewhat pitcher-shaped, with a remarkably oblique
or gibbous base. Zip quite enclosed within this, lying up against

column just below the stigma: the disk crested. Column as
long as the perianth, its base very decurrent. Anther-case
flattened at the top. VW. J. H.
Curt. From the circumstance that the roots of this Orchid
adhere firmly to the inside of the pot in which it grows, we may
infer that its natural habitat is in rocky places, where there is —
but little soil, and which are subject to a considerable degree of
dryness during a part of the year. With us it grows freely, if
potted in loose, turfy, peat soil, and kept in the warm division
of the Orchideous house. It should be planted a few inches
above the level of the mouth of the pot, and supported by a
substantial drainage ; for plants of this habit, when potted in
loose soil, are very liable, by their gravity, to sink below the
margin of the pot,—which not only gives the plant an unsightly
appearance, but causes the pseudo-bulbs to become crowded and
weak. This precaution is the more necessary, from the downward
tendency of the pseudo-bulbs (a circumstance common to many
bulbous-rooted genera), each successive formation being produced
from the base of the previous ones, and being sessile in their
attachment to them. They are thus liable to become, in time, a
crowded mass in the pot. When this happens, it is advisable
to divide the mass, and select the younger and healthier pseudo-
bulbs, to be repotted in the manner described above. J. 8.

Forty-five years ago this handsome plant was alluded to in an
excellent Memoir on Goniocarpus, published by Mr. Kénig in
the ‘Annals of Botany,’ vol.i. p.543, as existing in the Banksian
Herbarium, “a beautiful new genus, a native of California,
having the flowers of a Fuchsia anda fruit exactly like Epilobium.
These specimens were doubtless those of Mr. Menzies, some
of which we have also the good fortune to possess in our own
herbarium. No further notice seems to have been taken of it
till Presl, in the 2nd vol. of his ‘ Reliquize Heenkeane,’ published
it under the name of Zauschneria, in compliment to Dr. Zausch-
her, a Professor of Nat. History in the University of Prague.
Presl added, though doubtfully, a second species from Mexico ;
but if we consider his two plants as distinct, we must here make
a third, for our cultivated plant, as may be seen by Dr. Lindley’s
plant above quoted and by our figure, is as distinct from 7
Mewicana, as that is from Z. Californica. In some of Mr.
FEBRUARY Ist, 1850. c 2
Menzies’ original specimens the leaves are almost acicular, and
from the smallness of the upper leaves or bracteas, the flowers
are truly spicate. It makes an excellent plant for bedding
out, and our gardens are indebted to the Horticultural Society
for its introduction, through their collector Mr. Hartweg.
Descr. A low half-shrubby plant, varying extremely in downi-
ness upon the young branches and foliage. Leaves also extremely
variable in size and shape, and in the margin, generally in
native specimens linear or linear-lanceolate, but broader and
quite ovate in our var. y: all of them alternate, remote or
crowded: the upper ones in our plant scarcely diminishing in
size ; in other individuals, becoming small bracteas, one beneath
each flower. Yowers axillary, sessile, solitary. Calyx very
long, red, the lower portion united with the slender linear ovary ;
above the ovary the calyx-tube is funnel-shaped, striated, very
narrow below the middle, at the base swollen and articulated
(and eventually deciduous) upon the ovary: Zimé of four lanceo-
late segments. Within the mouth of the calyx are eight roundish
scales, four erect and four deflexed. Petals four, deep red, ob-
cordate, bifid, shorter than the segments of the calyx. Stamens
eight : filaments much exserted: anthers linear, fixed by the
middle of the back. Style longer than the stamens, filiform :
stigma peltate, four-lobed. Fruit four-valved, as in Hpilobium,
imperfectly four-celled. Seeds numerous, comose. W. J. H.
Cunt. This is a perennial plant, becoming somewhat suffru-
ticose towards autumn. It is closely allied to Zpilodium, and,
like most species of that genus, increases rapidly by its numerous
surculose roots (underground shoots). It is of easy cultivation,
growing freely on dry, good garden-soil. Its showy flowers are
produced abundantly during the latter part of the summer; and,
as it continues a long time in flower, it is worthy of being grown
in a pot, as an ornamental plant for the conservatory. It is
also deserving of a place in the flower-garden, as a bedding
plant, especially where variety is wanted ; for although its thin
and spare habit is rather against it, yet, by planting thick and
stopping back the shoots early in the season, the bed may be
made to assume a very fair degree of compactness before the
end of the summer. From the appearance of its roots at the
time we write, we infer that it will prove a hardy perennial ; but
in exposed situations it may be advisable to cover it over with
leaves or some such covering. It is increased readily by divi-
sion of the roots, also by cuttings and seeds. J. 8.

D. grandifiorus, and indeed brings it into another division of this

strongly veined and reticulated. Flowers sessile or very nearly
so, two together from the axils of the upper leaves, large, very

into five erect, subulate /odes, much shorter than the funnel-
shaped curved tube of the corolla: the /imé very large, purple
blue, veined, the five lobes rotundate, spreading, crenate and
somewhat waved at the margins. Stamens included. Ovary
ovate, downy, seated on a large disk. Style as long as the tube
of the corolla: stigma of two very unequal lobes. Capsule obo-
vato-clavate, acute, slightly downy, bearing eight or ten lenticular
seeds. W.J. H.
Curr. A soft-wooded plant of herbaceous aspect, growing
from one to two feet high. It is a native of the tem-
perate climate of Cuenca, in Peru. It is found to succeed
im a temperature intermediate between that of the stove and
greenhouse, and grows freely in any kind of light garden
soil. Like many of the tropical Acanthacee, after flowering it
soon becomes thin and naked. It propagates freely by cuttings.
The young plants should be kept in small pots during winter,
and receive very little water. In the spring they require to
be shifted into a large pot, where they will soon make rapid pro-
gress, and produce a succession of large fine blue flowers. //. S.

CLEMATIS graveolens. Lindl. in Journ. of Hort. Soc. v. 1. p. 307. cum Ic.
A small but elegant climbing species of Clematis, quite hardy
when planted against a wall, as may be expected from the fact’
that it is a native of Chinese Tartary and the snowy passes of
Western Himalaya, at an elevation of 12,000 feet above the
level of the sea. In such situations it was detected by our
friend Capt. Wm. Munro, of the — Regt., who sent seeds of
it to England in 1844; and, in similar localities, it was found
three years afterwards by Dr. Thomas Thomson, during his
interesting journeys into Thibet (as related in the recent volumes
of the ‘London Journal of Botany’), who sent the seeds to the
Botanic Gardens of Kew. It flowers through the summer
months. We could scarcely perceive any odour in the flower
of our plant; but that may depend on the state of the
atmosphere.
Descr. Our plant attains a height of about six feet, forming
a much branching climbing glabrous shrub. Branches slender,
obtusely angled. Zeaves opposite, variously divided in a pin-
nated manner, bi- or triternate; the leaftets all petioled, ovate or
lanceolate, entire or one- or two-lobed, odes acute or acuminate.
Peduncles longer than the leaves, slender, single-flowered. Buds

Curr. One of a very common genus of plants, which now
numbers about 150 described species, natives chiefly of tem-
perate climates. A few are herbaceous perennials; but by
far the greater portion are deciduous and evergreen ligneous
creepers, supporting themselves by their tendril-formed pe-
tioles, and growing in a crowded manner over bushes and
trees: the present species is of the latter kind. It has been
under our observation for two years, and appears to be quite
hardy. It will grow in any kind of garden-soil, and, like its con-
geners, is suitable for covering trellis-work or for planting against
a wall; but it does not appear to be a strong growing species.
It is readily increased by cuttings and seeds. /. S.

Discovered by Dr. Wallich in the mountain district of
Sylhet and Khasiya, and found in great abundance also by Dr.
Hooker as he approached Darjeeling in Sikkim-Himalaya, and
from him the specimens are derived, which are here represented,
Its range seems to be confined to the eastern extremity of the
Sub-Himalayan chain. Handsome as this plant is, individually
(for only one flower arises at a time from each pseudo-bulb, and
that always at a period when the leaf is absent), yet our repre-
sentation of three flowering pseudo-bulbs can give no idea of the
beauty of a tuft of more than twenty such bulbs, each with its
flower densely compacted, which I had the gratification of seeing
during my last visit to Chatsworth. Truly, next to the flowering
Victoria, this was the most interesting of the many botanical
rarities collected in that princely place. It flowers in the
summer and autumn.
Descr. The pseudo-bulbs are no less singular than the flowers
are beautiful: they are flagon-shaped, dark green, warted, and
frequently covered with a strong veining of loose net-work,
formed by the old sheath. From the top of this pseudo-bulb,
the broadly-lanceolate, solitary, membranaceous, plaited /ea/ arises;
and it is not till after its decay and disappearance, that the
flower springs laterally from the pseudo-bulb. It is almost

and resembling them, but smaller. Zip large, standing forward,
obovate, saccate at the base, the side-lobes complicato-connivent
over the column ; the intermediate lobe (almost continuous with
the long lateral lobes) is dentato-fimbriate at the margin, re-
curved; and the disk of the lip is furnished with five crested
longitudinal lamella : the colour of the lip is pink, white, and
yellow, here and there dashed with red spots. Column very
long, with a three-lobed wing at the apex surrounding the
anther. W. J. Z.
Cunt. A pretty Orchid, belonging to a group of Celogyne
which differs from the rest of Ne gens in rit Bias éiphytal
but growing on the ground in moist turfy places. The tender
pseudo-bulbs are found on the surface, or but little immersed ;
and the plant is in many respects analogous to the well-known
Bletia hyacinthina, and other species of that genus. After the
plant has flowered the leaves appear, and at their base the new
_ pseudo-bulb begins to be formed. At this period it should
be kept moderately moist and warm; but after the bulb is
fully formed, and the leaves decay, the supply of moisture must
_ be lessened, only sufficient being given to keep the mould
from becoming quite hard and dry. It appears to thrive best
when kept in the cool division of the Orchideous house, and
placed near the glass. Turfy peat, mixed with a portion of —
chopped sphagnum moss, will suit it, care being taken that the
pot be well drained, and that it never be allowed to remain long
saturated with water. On account of the old bulbs dying soon
after the new ones are formed, it increases but slowly. J. 8.

A really shrubby and, as recorded by Dr. Lindley, though
it has not proved so this winter (1849-50) with us, hardy
plant, copiously branched, and at first, with its numerous very
leafy branches, not having much the aspect of a Pentstemon.
Such, however, it really is, and a native of California, where it was
detected by Mr. Douglas in 1831: and does not appear to have
been found by any traveller since, till Mr. Hartweg met with
it on the mountain of Santa Inez in California in 1848, when
seeds were sent by him to the Horticultural Society. It produces
its bright scarlet flowers among the copious foliage during the
summer months.
Descr. A rather weak and straggling shrub ; but with a little
Support and training it become a very handsome one, with ob-
scurely four-sided stems and branches. Leaves cordate, acute, nearly
sessile, subcoriaceous, evergreen (?), strongly and coarsely ser-
tated. Flowering-branches numerous, leafy, bearing several
Opposite dranchlets, which are terminated by a moderately-sized
flower. Pedicels glandular. Calyz large in proportion to the
flower, glandular, cut to the base into five rather unequal, lan-
ceolate, acute, erecto-patent Jobes. Corolla an inch and a half or
nearly two inches long, bright scarlet: the ‘be almost cylin-

drical, straight, or very slightly curved: the md deeply two-
lipped ; upper lip straight, linear, emarginate at the point, lower
lip spreading out into three lmear obtuse segments. Stamens
longer than the tube: anthers ovate: fifth or sterile filament
with a remarkably strong beard on one side, resembling a brush.
Ovary ovate, seated on a fleshy disk: style as long as the
filaments of the stamens: stigma obtuse. W. J. H.
Cuur. This very distinct species of Pentstemon is of a slender,
suffruticose, spreading habit, growing luxuriantly and flowering
freely during the summer. It appears well-suited for orna-
menting the fronts of shrubberies and flower-borders; but we
fear it may not prove hardy, for it was much injured by the
first frosts of last October, and at this time we see no symptoms of
life above-ground. It will, therefore, be best to treat it as a
half-hardy plant, covering it over on the approach of winter with
dry leaves or other loose protecting material; but as it is easily
increased by cuttings, a stock should be kept in small pots in a
cool frame, ready for planting out in the spring. J. 8.

Mr. Tweedie's Golden-flowered Cereus.
Nat. Ord. Cactea.—Icosanpria Monoeynia.
Gen. Char. (Vide supra, Tas. 4417.)
Currus Tweediei ; erectus cylindraceus glaucus polygonus, costis obtusis
sequalibus (non tuberculatis), areolis copiosis ovalibus fusco-lanatis, spinis
numerosis inzqualibus 4-5 validioribus albis fusco-variegatis quorum 3-4

One of the prettiest of the Cereus group of Cactea, of a pecu-
liarly glaucous tint, bearing in the latter end of summer, when
little more than a foot high, copious, rather large, and very
handsome flowers, elegant in shape and bright in colour. We
are indebted for the possession of our largest and flowering
plant at Kew, to Messrs. Lee, of the Hammersmith Nursery, but
we received seeds from Buenos Ayres through Mr. Tweedie. It
flowered for the first time in September 1849. I can find no
species described that at all corresponds with it. ;
Dzscr. Our tallest plants are about a foot toa foot and a half high,
and an inch in diameter, of a very glaucous green hue, simple, but
increasing readily by offsets at the base. The shape is cylindrical,
very slightly tapering upwards, numbered with many, about six-
teen, moderately deep furrows, perfectly straight, the ridges obtuse
and even (not tubercled or mammillate). Areole on the ridges
approximate, oval, woolly, the wool brown. pines many from
each areola, of which four or five are stouter than the rest,
white, blotched with brown, and of these stout ones three or
four (half to three-quarters of an inch long) are erecto-patent ;
a solitary stout one generally together with the other lesser ones,
which are white, all point downwards. Flowers, of a rich orange-
crimson, are numerous from the side of the stem, three inches

long, curved upwards, the mouth oblique. Calya-tube funnel-
shaped, the scales remote, subulate, appressed, lower ones ciliated
with white hairs. Petals small, scarcely longer than the teeth of
the calyx, deep yellow, acute. Stamens lying against the upper
side of the tube, and there much longer than the flower: lower
ones scarcely protruded. Anthers deep purple. W. J. 7.
Curr. A pretty species of Cereus, of an erect, stiff habit,
and apparently not of tall stature, having produced its flowers
when less than two feet high. It grows freely in a soil com-
posed of light loam, leaf-mould, and sand, care being taken that
it be not retentive of water. The pot should be well drained,
and the mould must never continue long saturated. ‘The latter
precaution is especially to be observed in winter, for during that
season the plant requires little or no water. We are not
acquainted with its native locality, but judging from the climate
of Buenos Ayres, we may suppose that it endures great ex-
tremes of temperature, and often long droughts ; the thermometer
in summer sometimes rising to 94°, and in winter falling so low
as 36°; the mean temperature of summer and winter being
respectively 72° and 54°. With us, a night temperature
averaging 50° during the winter suits it; but in severe wea-
ther it is not advisable to maintain that heat, for the plant
does not suffer even when the thermometer is 10 to 15 degrees
lower. When this is the case, however, it is desirable that a
corresponding rise be maintained during the day. As the
warmth of spring increases, the plant should be moderately
supplied with water. In summer it should be allowed to receive
the full power of the sun, with occasional syringeing over head :
this operation must be performed after the heat of the day has
declined, or early in the morning. J. S.

(In our last number, under Celogyne Wallichii (Tan. 4496.), we spoke,
from memory only, of the extreme beauty of that plant at Chatsworth, Mr.
Paxton has been so obliging as to inform us, it consisted of “eight pseudo-
bulbs, which bore twenty-eight flowers: three of the pseudo-bulbs were large,
three of a medium size, and two small. The three large ones each produced
three flower-stems, and two out of three on each bulb were biflorous. Of the
three medium-sized ones, one had four flower-stems, and the other two had
three ‘stems each, all single-flowered. One of the two small bulbs bore two
flowers on the stems, and the other bulb was single-flowered.”]

Two of the most interesting plants, interesting especially to the
lovers of arboriculture, among those detected by Mr. Fortune, during
his present second visit to the north of China, are most assuredly
the Cupressus Junebris, Endl. (C. pendula, Staunton and Lambert,
not of Thunberg), and the subject of the present plate. Messrs.
Standish and Noble, of the Bagshot Nursery, are the fortunate pos-
Sessors of young plants of both, and have already found them to
be perfectly hardy in this climate. Both were found by Mr.
Fortune two hundred miles north of Shang-see, from which
latter place a Palm (Chamerops eacelsa, Th.) sent to the Royal
Gardens by Mr. Fortune, has braved, unharmed and unprotected
by any sort of covering, the severe winter now passed (1849-50).
MARCH Ist, 1850.
To judge of the graceful character of the Funereal Cypress, one
has but to look at Tab. 41 of the Atlas of Plates accompanying
Lord Macartney’s Embassy to China, where we learn that in
the north of China it is the tree used to adorn cemeteries ;—and,
with regard to the present, which is of the Yew tribe of Conifere,
the large size of the foliage, with its pectinated arrangement on
the branches, must give it a pre-eminence over all other Zaxinee.
Our flowering-plant (male flowers only) is drawn from a dried
specimen sent home by Mr. Fortune, aided by a recent twig
from Mr. Standish’s nursery. These male flowers show clearly
that it belongs to the genus Cephalotacus of the lamented Endli-
cher. Insome respects it approaches the Japanese C. pedunculata
of Sieb. and Zuccarini, Fl. Jap. v. 2. p. 133; and we regret that
our bookseller has not yet supplied us with the Fasciculus con-
taining this species ; but if Endlicher is correct in referrmg Zacus
Harringtonia of the Pinetum Woburnense, t. 68, to it, we may
safely assert that our plant is not the same, but a perfectly un-
described species.
Descr. In the absence of a well-grown plant, we can say
little or nothing of the tree, save that it is stated by Mr.
Fortune to grow to a height of from forty to sixty feet. Its
branches are probably spreading or drooping, obscurely
streaked or furrowed, distichous, pale brown, slender. Leaves
quite distichous, alternate or opposite, approximate, three to
four inches long, linear, tapering a little at the base, much
and gradually acuminate, one-nerved, dark full green above,
- paler beneath. From the axils of numerous leaves the male
capitule of flowers appears, globose, about as large as a small
pea on a short scaly stalk. This head consists of several
imbricated, broadly ovate, almost round, concave, brown, erose
scales, including a little amentum of stamens. A filament ter-
minates in a small scale, bearing three pendulous anther-cells.
Female flower and fruit at present unknown. W. J. H.
Cuxr. This is described as forming a handsome, spreading, ever-
n tree. It comes from the north of China, and, as might be ex-
pected, is perfectly hardy. A plant in the Bagshot Nursery stood
in the open air during the last winter, without being in the least
injured. As it increases from cuttings as readily as the common
Yew, and grows freely, we may expect to see this rare tree soon
become common. We learn that Mr. Standish has already a
considerable stock of young plants. J. 8.

highly ornamental, its bright red tufts of flowers contrasting
strongly against the delicate green foliage. It is readily in-
creased by cuttings, which should be planted under a bell-glass

A climbing, copiously-leaved, evergreen shrub, native of Chili,
and growing as far south as Concepcion, whence it was naturally
supposed to be hardy, and experience has proved the correctness
of this opinion, for it has braved the winter of 1849-50 without
any covering or protection, other than that afforded by a wall,
both at Exeter and at Kew. George Thomas Davy, Esq., who
has the credit of introducing this plant by sending it to Messrs.
Veitch of Exeter, writes to them thus :—‘ When I first saw it in
the Province of Concepcion, I was so much struck with the sin-
gularly dark colour of the flowers, and the beauty of the foliage,
MARCH Ist, 1850. _
that I gave instructions to have a root sent to me at Valparaiso,
which was done ; and it is the plant now in your possession. The
fruit is sold in the Chilian markets.’’ According to Decaisne,
cordage is made of the tough fibre. The plant above alluded to
was brought home from Valparaiso by Mr. Wm. Lobb, and was
in full flower in Mr. Veitch’s Nursery in December, 1849:
and to Mr. Veitch we are indebted for the specimen figured in
the annexed plate.
Descr. A climbing shrub, with terete, but often twisted
branches, bearmg Jeaves, which, especially in the flowering
branches, are generally simply ternate, but sometimes bi- and
triternate: the /eaflets petioled, subcoriaceous, evergreen, ovate,
here and there almost spinosely dentate, dark green above, paler
and reticulated beneath. Peduncles solitary, from the axil of a
leaf: at the base bearing two large unequally cordate spreading
bracteas :—these we also find at the axil of the leaf, even where
there is no flower-stalk. Flowers forming a dense drooping
spike of numerous, rather large, deep purplish chocolate-coloured
flowers. We have only seen male flowers, as here represented.
The calyx is of six rhombeo-ovate, spreading, fleshy sepals,
nearly equal in our specimens. Corolla of six spreading, lanceo-
late, or almost subulate, white, mealy, membranaceous petals.
Stamens six, united into a column, and bearing six spreading,
oblong, slightly incurved, apiculated, two-celled anthers, opening
at the back. 7. J. H.
Cuxr. This is a native of woods in the south of Chili, and proves
perfectly hardy in this climate. A plant in this garden has
withstood the cold of the last three winters without injury, and
Mr. Veitch informs us that in his nursery there is a specimen twelve
feet high, growing against a wall. It is a beautiful evergreen
creeper, with dark green foliage, and well adapted for covering
high walls. It is a rapid grower, and apparently not particular
as to situation; but, from its habit, we infer that shady places
suit it best. J. 8.

Every one has heard of the “ Jamaica Lace-Bark,” and has
inspected the curious and beautiful substance : few have seen spe-
cimens of the leaves and flowers, still fewer have seen the living
plant, nor was it, we believe, permanently introduced in the latter
state to Europe till the year 1844. The year before that, our
intelligent Collector for the Kew Gardens, Mr. Purdie, was
instructed to take the island of Jamaica on his way to New
Granada, and visit the quarters of this plant (the parishes
of Vere, Clarendon, and Elizabeth), to which it seems to be
confined. Mr. Purdie spent some days among woods of this
tree, but could find neither flower nor fruit in a state fit to send
home. But our wishes being known to Mr. Wilson, the inde-
MARCH Ist, 1850.
&
fatigable Curator of the Botanic Gardens at Bath (Jamaica), he
kindly procured seeds and young plants a few months later, and
has been the means of introducing this rarity to our stoves.
Our plants are now eight to ten feet high, and one of them
produced, for the first time, flowers and fruit copiously in the
summer and autumn of 1849.
It is well known that the liber or inner bark of this tree con-
sists of layers of reticulated fibre, exactly resembling well-
prepared lace; and its nature is best exhibited by taking a
truncheon from a branch, tearing down the bark, and sepa-
rating it by the hand into as many layers as that portion of the
tree is years old. ‘The ladies of Jamaica,’ Dr. Lunan observes,
“are extremely dexterous in making caps, ruffles, and complete
suits of lace with it. In order to. bleach it, after being drawn
out as much as it will bear, they expose it (stretched) to the
sunshine, and sprinkle it frequently with water. It bears wash-
ing extremely well with common soap, or the “curatoe”’ soap,
and acquires a degree of whiteness equal to the best artificial
lace. The wild negroes have made apparel with it of a very
durable nature ; but the common use to which it is applied is
rope-making. ‘The Spaniards are said to have worked it into
cables, and the Indians employ it in a variety of different
fabrics.” —Sloane relates that Charles II. had a cravat made of the
bark of this tree, which was presented to him by Sir Thomas Lynch.
In the days of slavery the negro-whips were commonly made of
the branches of this tree, thus :—of a portion of the branch the
wood was removed, and the bark twisted into the lash. The
lower part of the branch formed the handle, and if it was desired
to ornament the latter, it was done by unravelling the bark at
the lower end, which thus formed a kind of tassel consisting
of spreading layers of lace. On the plate above quoted in the
Kew Garden Miscellany, a specimen of the lace itself, a whip,
&c., are represented, from the objects in the Museum of Kew.
Dzscr. A éree from twenty to thirty feet high, with branches
too straggling and foliage (though of a good size and glossy) too
sparse to form a striking object, though really handsome when
in flower. Leaves alternate, on rather short petioles, which are
jointed on the branch ; hence the leaves readily fall off in drying;
they are cordato-ovate, acute, glossy, reticulated, palish-green.
Flowers pure white, or, in bud, greenish-white, arranged m
spikes which are solitary and terminal on a main branch, or on
short side-branches. Perianth urceolate, fleshy, four-toothed.
Stamens included : longer filaments arising from a scale : anthers
subglobose. Pisti/ included. Ovary ovate, densely silky. Sty/e
shorter than the ovary. Stigma obtuse. The fruit is a smooth,
oval drupe. W. J. H. 3
i
Curr. In the second edition of the ‘ Hortus Kewensis’ it is
Stated that the Lace-Bark tree was introduced to this garden by
Rear-Admiral William Bligh in 1793; but it appears to have
been soon lost, and it had been a desideratum in the garden for .
many years.. Our present plants were received in 1844, and
were then only four inches high. For our guidance in their
cultivation, Mr. Wilson informed us that “it is invariably found
growing in very dry situations on marly limestone hills, where
there is not a particle of earth to be seen. The young plants
grow in the crevices, or honeycomb, as it is called, and in order
to obtain them with roots, a hammer or large stone is required
to break away the porous limestone.” He further adds, that
“the soil for growing it in should be composed of one-third
marl or lime-rubbish ; for I am persuaded that pure loam will
kill them.”” We are always most desirous to pay attention to
information as regards the native habitats of plants; but in
cases like the present we have found that, when too strictly
adhered to, successful cultivation does not always follow. In
our experience, we have never found any plant thrive by re-
taining it in its native soil, or in soil too closely resembling it. If
we could also imitate all the various influences of climate that
modify and control the growth of plants in their native localities,
it might then be proper for us to cultivate the Lace-Bark tree
in marly soil, like limestone ; but our plants afford evidence
that such soil is not required when they are grown in an arti-
ficially heated atmosphere. We have used good yellow loam,
mixed with a little leaf-mould and sand. In this they have
attained the height of eight feet, and continue in a perfectly
healthy state. In their native place the leaves are deciduous,
falling off in the dry season. But the health of a general collec-
tion of tropical plants, grown in a hothouse,*will not allow us
to put them under the influence of their xatural dry season: we
therefore find that some individuals change their habit,and become
evergreens. his has been the case with the Lagetta plants ;
and it is probably to an accidental circumstance that we owe the
present production of flowers. One of the plants appeared
to have received some check, which caused it to shed its leaves :
the consequence was, that just before the unfolding of the young
foliage, it produced its flowers. Like many of the Thymelacea,
the Lace-Bark tree is difficult to propagate. We have never suc-
ceeded by planting cuttings, nor by grafting it on species of allied
genera ; but we now have hopes of propagating it by es

AEscHYNANTHUS Javanicus. Hort. Rollinson.
Messrs. Rollinson, of the Tooting Nursery, obligingly sent
us the accompanying very handsome Mschynanthus, under the
name of @. Javanicus, received by them, we presume, from
their Collector in Java. At first sight it bore so much resem-
blance to the Z. pulcher, De Cand.,.figured at our Tab. 4264,
that I was disposed to consider it a variety ; but as that happened
to be in flower at the same time in the stove of the Royal
Gardens, the differences were found to be too striking to allow it
to be other than a good species. The plant is more compact,
the leaves smaller, the flowers all over downy, as well as the
pedicels, the calyx truly cylindrical (not swollen below), the
limb spreading, the corolla more slender and graceful, the
Stamens exserted.
Descr. A scandent, yet compact-growing, soft-stemmed shrub,
much branched and rooting from beneath the petioles. Stems
terete ; the younger ones green and succulent. Leaves opposite,
ovate or oval, sometimes approaching to oblong, between coria-
ceous and fleshy, obscurely angulato-dentate, penninerved, the
herves sunk in the substance of the leaf. Corymbs terminal, of
many, large, handsome, richly-coloured flowers. Pedicels downy,
bracteated, bracteas ovate or cordate, unequal. Calyx ample,
greatly wider than the tube of the corolla it includes, downy,

dark-green, red-brown above; the ¢wée cylindrical, faintly stri-
ated, the five lobes of the /imé spreading horizontally. Corolla
bright red, about thrice the length of the limb, the tube slender,
infundibuliform, downy, laterally compressed, with a prominence
under the throat: mouth oblique, imdb of four nearly equal,
spreading, large, ovate /obes, the upper one notched, the rest
entire and streaked and blotched with yellow. Stamens all ex-
serted, especially the upper ones. Ovary very long, slender, its
pedunculiform base downy and inserted into a five-lobed cup-
shaped annulus. Style continuous from the ovary : stigma ob-
lique, a depressed head. W. J. H.
Cutt. Belonging to a genus of East Indian plants charac-
terized by a trailing, or somewhat scandent, epiphytal habit, and
analogous to Nematanthus and Alloplectus of tropical America,
this plant requires the same kind of treatment, and they may be
properly associated with tropical Orchides. It is a trailing
species, of neat habit, and may either be grown in a pot or
basket suspended from the roof of the house, or placed on an
elevated position formed of any convenient material, such as
rude bricks or garden pottery, covered with sods of turfy peat.
By introducing a few small-growing ferns, or Lycopodia, the
whole will soon assume a natural appearance. During summer
the plant requires to be freely supplied with water; and if
placed in a position exposed to the midday sun, it should be
shaded. In the winter months water must be sparingly
given. J.S. 32.

A very handsome copious-flowering and _bright-coloured
species of Gesneria, quite new, as far as I can find: but
approaching nearest 1o G. longifolia, Lind. Bot. Reg. 1842,
tab. 40, but differing much in the form of the leaves, and in
the limb of the corolla. It was discovered by Mr. Seemann, at
Panama, and I have thought it rving of bearing the name of
its discoverer, who sent roots to the R oyal Gardens of Kew, in
1848. ‘The flowering plants were produced in October 1549.
Descr. Roots tuberous, I believe, but these I had not the
opportunity of inspecting. Stem two feet or more high, simple,
rather stout below, nearly terete, villous with spreading hairs,
as is almost every part of the plant. Leaves opposite and ter-
nate, the lower ones large, broadly ovate or subobovate, on
rather long petioles, coarsely serrate, acute, rather than acumi-
nate; upper ones gradually. smaller and more tapering to a
point, all obtuse at the base. From the whorls of the upper
floral leaves, the hairy peduncles appear fasciculato-verticillate,
longer than the petioles, and the uppermost ones longer even
than the leaves, single-flowered. Calya shallow, cup-shaped,
with five nearly regular, acute, spreading lobes. Corolla very
villous, bright ‘brick-red, a little inclining to orange. Tide

and clothed with glandular hairs. Stamens and style included.
Ovary roundish-ovate, very villous, having at the base four con-
spicuous, hypogynous, broad glands, of which one is bifid. W.J.H.
Curr. About seventy species of this genus are now described.
They are all natives of tropical America and the adjacent islands,
and, being highly ornamental plants, a considerable number of
them have been introduced. They may be characterized as being
(chiefly) herbaceous plants, producing their showy flowers on a
soft, leafy stem, that rises from a rhizome, which is either in the
form of a thick, fleshy, round tuber, or it consists of a number
of fleshy scales, compactly seated on an elongating axis, and,
therefore, analogous to an under-ground surculose stem. The
rhizome of the species now figured belongs to the latter form, -
resembling that of Gloxinia and Achimenes, and requiring the
same kind of treatment. It will thrive in a mixture of light
loam and leaf-mould; and, in order to start the roots, they
should be placed in bottom-heat in a warm stove, taking care
~ not to give much water till after they have made some progress
in growth. If during the summer they happen to be placed in
a position fully exposed to the south, they will require to be
shaded during the middle of the day. /. 8.

We have before had occasion (as have other authors) to com-
plain of the careless manner in which plants are named that
are sent from the continental nurserymen, and more so than of
any others in the,case of some of our Belgian correspondents.
The Royal Gardens received. the present plant from Mr. Makoy of
Liége, without any mention of its native country, under the name
of Syphocampylos canus; a species of Brazil, and which inno
particular corresponds with the present plant. We doubt if it
can be referred to any described species of the genus. It appears,
however, to agree better with Zupa than with Syphocampylos, it
the genera be really well founded. It flowers in the greenhouse
in the summer and autumn. i.

after the manner of the Daphne Laureola. Leaves soft, four to
six inches long, patent or deflexed, lanceolate or broad-lanceolate, .
acute, serrated, tapering at the base into a short footstalk, dark
green and slightly downy above, tomentose and hoary beneath.
Peduncles axillary, solitary, one to two inches long, woolly.
Calyx woolly: tube semiglobose, five-angled; the /imé of five
acuminated spreading segments. Corolla yellowish or greenish-
red, at length quite red: tude two inches long, nearly straight,
laterally compressed; dims two-lipped, Zips long, superior one
inclined upwards, bifid, segments linear acuminate; /ower lip
deflexed, trifid, segment linear-lanceolate. Anthers shorter than

Cuur. This is a soft-wooded, suffruticose shrub, of an erect,
stiff habit, becoming naked below. It requires to be placed
during winter in a temperature that, on an average, need not
exceed 55°; and, on account of its soft, tomentose nature, the
hygrometric state of the atmosphere should be kept rather dry.
In spring it should be repotted, first divesting the ball of a
portion of its old soil, and then planting in a fresh mixture of
light loam and sandy peat. Care must be taken that the pot be
well drained, and that at no time the mould be allowed to re-
main long saturated ; for in plants of this nature, if kept too
wet, the woody parts of the roots near the surface are liable to be
destroyed, while the appearance of the plant, above ground,
continues for a time in a healthy state. During the summer it
may be placed in the greenhouse. We have not yet had sufli-
cient experience respecting it, yet we believe that it would grow
vigorously if planted about May in a warm border ; but as it is
a late flowering plant it would be necessary to take it up and
repot it, and place it under protection in time to save it from
being injured by the autumn frosts. It is readily increased by
cuttings, put under a bell-glass and treated in the usual way. JS.

A native of Mexico, and, as may be expected, a greenhouse
plant. It has been for some time cultivated at Kew. Our
specimen here figured was communicated by Mr. Veitch from
his rich garden at Exeter, and is really a pretty thing when
well cultivated. It flowers during the summer months.
Descr. A low deciduous shrub: the. branches with reddish
bark ; younger twigs green. Leaves. opposite or ternate, lanceo-
late or ovato-lanceolate, entire or denticulato-serrate, small,
nearly sessile, penninerved. Peduncles axillary, from one- to three-
flowered. Flowers on slender, drooping pedicels, springing from
the copious upper and younger branchlets, and thus forming a
rather large, leafy ¢hyrsus or compact panicle. Ovary glabrous
(as is every part of the plant), red, globose. Calya also deep
red: its tube cylindrical, contracted where it unites with the
ovary, and spreading upwards into four ovato-acuminate seg-
ments. Petals deep rose, subobcordate, spreading, nerved,
bearing a blunt mucro at the retuse apex. Stamens eight ; four
nearly equal with the throat of the flower, four others more
exserted. Style much exserted, longer than the longest stamens.

plants may be safely placed under the stages of the greenhouse,
or in other such place, provided the plants are kept dry, and the
place sufficiently cool to prevent them from beginning to grow
before sprmg. They must then be taken out of the pots, the
roots divested of part of the old soil, repotted in a mixture
of light loam and leaf-mould, and then be placed so as to receive
the necessary stimulants for bringing them into a flowering
state. As they advance in growth and begin to show flower,
they may be removed into the greenhouse. In summer the
plants thrive if set in an open border, along with other Fuchsias
and such like summer plants. They are readily propagated by
cuttings. J. 8. ?

» many fine things discovered by Mr. Drummond
during his excursions in the interior to the south-west of the
e. Swan-river settlement. He could not fail to be struck with the
. Ree magnificence of this plant, three or four and more feet high,
o growing in masses, and bearing paniculated branches and co-
pious flowers clothed with dense tomentum of the richest Tyrian
purple. Seeds have been sent home, but they have not yet
germinated. Happily, however, as stated on a former occasion,
the well-dried specimens of the species of this genus retain their
form and colour almost equally with the living plant, and we are
hence able to present an accurate figure to our readers. Its
nearest affinity is perhaps with the 4. fuliginosa, Bot. Mag.

in colour.

Curr. This belongs to a genus of Australian plants, similar in
habit to the common Flower-de-Luce. It has narrow, sword-
shaped leaves, that rise from a thick fleshy rhizome, which in-
creases by lateral offsets, and in time becomes a crowded, cespi-
tose mass; the flowers are produced in a kind of corymb,
on a naked, generally erect flower-stalk, rising above the leaves,
which, on account of their permanent nature, may be termed ever-
green. Several species of the genus have been long known to
us as garden plants. They are of a robust nature, requiring
protection during winter, but will flower in the open air during
summer, at which time they require a liberal supply of water.
On account of their dense habit of growth “it is advisable to
divide the mass, and select the young and most vigorous plants
for repotting, which should be done in autumn or early in
spring. The soil in which they are planted is not important,
any kind of light loam suiting them. As the species now figured
is not, to our knowledge, yet introduced into this country, we
can only infer that a similar treatment will be suitable. /. 8.

This constitutes a small tree, branching chiefly at the top, a
native of Brazil, flowering in our stove in the winter months,

old inhabitant of this garden, having for many years shown itself
conspicuously in the great old hothouse, where, on account of its
strong tendency to grow upwards, it was necessary to cut it
back every year to prevent its branches growing through the
glazed roof. It is now removed to the palm-house, where it
will have ample room for some years to come. Being a rude
and fast grower, it requires no particular treatment. It is a
deciduous tree, losing its leaves during the winter, and pro-
ducing its flowers in the spring just before the expansion of the
new leaves. It can be increased by cuttings of ripened wood,
placed under a bell-glass and plunged in bottom-heat, care being
taken that they are not kept too wet, for, being thick and some-
what soft-wooded, they are liable to rot. J. S. ‘

China has already afforded many beautiful plants to the
gardens of the curious in Europe, and our present relationship
with the Celestial Empire will doubtless be the means of the
introduction of many more. We have lately been gratified by
receiving from Hong-Kong, both from Captain Champion and
Mr. Braine, seeds, and, from the former gentleman, a dried
flower and leaf, together with a drawing by a Chinese artist, of
a perfectly new and most beautiful plant, which, after as accurate
an inspection as our materials will allow, we do not hesitate to
refer to Hamamelidee. All we know (and we desire to apologize
for the deficiencies) we lay before the public as speedily as
possible. Better specimens will doubtless, by and by, reach
us ; and, though our seeds have not yet germinated, we do not
yet despair of them. Captain Champion, writing from Hong-
Kong, December 1849, says, “This is admitted by all here to
be the handsomest of Hong-Kong flowering trees, and new to
Europeans till I discovered it in February last. It is a small
tree, but would probably, like the Camellia, blossom as a shrub
profusely, each branch bearing six to eight flowers. Flowers

diameter. Sepals (leaflets of outer involucre) about twelve.
Petals (leaflets of inner involucre) rose-coloured, about eighteen.
Stamens thirty to. forty (probably fifty in each head, Ep.). Fruit of
five radiating capsules; each about the size of a small hazel-nut,
birostrate, two-celled, many-seeded : in the young state crowned
by two long filiform styles. Leaves long, petiolated, bright
green, glaucous beneath. /owers in February, and the fruit
only attains its full size and ripens in September, splitting when
ripe from the apex downwards.—Conditions of growth exactly
those of Camellia Japonica, I should say ; and the tree of about
the same degree of hardihood: the young trees Mr. Braine has
transported thrive very well. There was a tree of Camellia
Japonica in flower in the same wood, also C. oleifera, and another
probably new species, together with Dr. Siebold’s Benthamia,
a new and very fine Perguluria, an Ornus, six or seven Oaks, a
Chestnut, a Liquidambar, and other rare trees.”
The opinion of my valued friend Mr. Bentham on my im-
perfect materials, is worth recording. “Your plant,” he says,
“is allied to Altingia (or the Javanese Liguidambar), and Sedg-
wickia. Sedgwickia is described as exinvoluerate, and in my
specimens there is no appearance of there having been any in-
volucre ; but the young shoots issue from buds covered with
. Inbricate scales, of which the inner ones are larger and more
coloured than the outer ones ; and one of my heads of fruit pro-
ceeds from one of those sets of scales, without any leaves inter-
vening, so that the scales form almost an involucre. The true
American Liguidambar is also without involucre ; but the Ja-
vanese one is described as having a deciduous one, and probably
Altingia, Liquidambar, and Sedgwickia will be found to be three
distinct genera—all apetalous and with an almost obsolete calyx,
all pleiandrous, bicarpellary, distylous, pluriovulate :—and in all
these characters, as well as in the capitate inflorescence and
concrete capsules opening at the apex, your new genus agrees
with them. But <Altingia and Liguidambar are unisexual, and
Sedgwickia, which, like yours, is hermaphrodite, differs from
yours in the want of involucre, or rather in the scales of the
gemme- being very deciduous, enclosing leaves as well as flower-
heads, and not being petaloid, whilst in yours each gemma
encloses only a single flower-head, and has the inner scales so re-
markably developed and petaloid ; and, also, your styles are long
and straight, whilst those of Sedgwickia are short and recurved as
in Liquidambar.” W.J. H.
Curr. Our only knowledge of this pretty plant is derived
from a small specimen sent from Hong-Kong, along with its
seeds. We received them last December; and, although we
have been most anxious to obtain this interesting plant in 2
living state, and have treated the seeds in various ways, we have
not yet had the satisfaction of seeing them vegetate, and fear
that this is another instance of the uncertainty of obtaining seeds
from distant countries in a perfect state; for even when sent with
all necessary care, aided by rapid conveyance, numbers of seeds:
lose their vitality before we receive them,—thus causing much
disappointment. For safety, they are often packed ina 2
tin case, or wrapped in oil-cloth or other close material; but it
has been invariably found that when they have been so sent.
there is less probability of success in raising them. The mischief
takes place generally ‘on board ship in coming through the ©
tropics, for, on account of the moisture the seeds contain, the
heat produces a degree of fermentation, which destroys their
vitality. This is more particularly the case in large seeds, and
in such as contain much albumen, especially if they are of an
oily nature. In preparing seeds for transmission through the
tropics, our experience leads us to recommend that they should
be wrapped in a paper parcel, and placed in the cabin or other
cool part of the ship, but not in a place that is too airy and dry.
In recommending this, we must be understood to refer more
especially to small seeds ; for, with all due care, we do not anti-
cipate much success with acorns and such other large seeds. /.S.

Long and well as this has been known as the most valuable
of tropical fruits, I can quote no good and faithful representation,
save in the costly work of Jacquin above cited. It is the more
gratifying, therefore, that our plants in the stoves of the Royal
rdens are bearing annually flowers most abundantly, and fruits,
though comparatively sparingly. Fortunately, our plants are of
the choicest kind of the East Indies, the Muldah, sent by Dr.
Wallich to Kew, and the fruit has a remarkably fine flavour.
Dr. Roxburgh, who had occasion to observe that “of this
tree, though one of the most common in India, he had not met
with any description which deserved the name,” has given the
best and fullest account of it, in the Flora Indica above quoted.
Although cultivated generally throughout the warm parts of Asia,
it does not appear to be certainly known in a truly wild state.
Dr. Wallich met with a tree (not in flower) which he considered to
be this, “seemingly wild, near Hetouma, on the banks of the
Karra or Karrara rivulet.”’ Beat
The ripe fruits, says Roxburgh, “are universally eaten, and
esteemed the best fruit in India : jellies, preserves, tarts, pickles,
&c., are made of them before they are ripe. The kernels are
large, and seem to contain much nourishment, but they are
made no use of except during times of scarcity and famine;

when they are boiled in the steam of water, and used as an article
of diet. The wood is of a dull grey colour, porous, yet pretty
durable if kept dry, but it soon decays if exposed to wet. In
very large old trees it acquires a light chocolate-colour towards
the centre of the trunk and larger branches, and becomes hard,
close-grained, and much more durable. From wounds made in the
bark there issues a soft, reddish-brown gum-resin, which age
hardens, and renders exceedingly like Bdellium. Laid on the
point of a knife and held in the flame of a candle, it readily
melts, catches flame, and burns with a crackling noise, emitting
a smell resembling that of Cashew-nuts when roasting. Its
taste is slightly bitter, with some degree of pungency. It
dissolves almost entirely in spirits, and in a great measure in
water: both solutions are milky, with a small tinge of brown.”
The next best account of the Mango we find given by our
friend Dr. M‘Fadyen, in his Flora of Jamaica; for, as may be
supposed, so highly prized a fruit has been introduced to almost
all tropical European colonies ; though to the West Indies
(Jamaica) not till the year 1782, and then by accident,
among a number of valuable plants taken in a French vessel
from the East Indies on its way to St. Domingo. They were
first cultivated in the garden of H. East, Esq., which afterwards
became the Botanic Garden, St. Andrews, and there being a
‘great number of plants producing several varieties of the fruit,
they were regularly numbered. Hence, two of the most esteemed
sorts have since come to be generally known by the name of
No. 11 and No. 32, No. 11 being a flat-sided green fruit, of a de-
licious aroma and an agreeable subacid taste. The No. 32 (cor-
responding, we believe, with our plant here figured, the Wuldah
of the East Indies) resembles it in form and fragrance ; it is of a
yellow colour, and possesses a more luscious sweetness. It is
now the most common of West Indian fruit-trees, very pro-
ductiye, and not only sought after by man, but by all the
domestic animals. It fattens hogs and horned ’stock, and to
horses will supply, in a great measure, the place of corn. The
finer varieties are considered by many not inferior to the Pine-—
apple. They are very wholesome ; and it is supposed their slightly
terebinthine taste prevents the generating of worms. They are
eaten plain, or sliced, with wine, sugar, and nutmeg. <A very
palatable spirit is obtained from the juice of the fruit and vinegar.
In India the best kinds’ are increased by layers or grafting by
approach.— With us its flowering-season is the early spring, and
the fruit ripens in October and November.
_ Descr. Fine as our largest Mango-tree is (thirteen feet high), it
is a dwarf compared with its ordinary size in the tropics. M‘Fadyen
speaks of the trunks being thirty to forty feet high,and Dr. Wallich
—
ce
says they are from ten to fifteen feet in circumference; “a
grove of that size,’ says Dr. Wallich, “is before my door.”
Branches numerous, more or less spreading. Leaves copious,
alternate, petiolate, chiefly from the extremities of the young
shoots, oblong-lanceolate, acuminate, six or eight inches and more
long, firm, almost coriaceous, entire, penninerved, bluish-green,
paler beneath: petioles one to two inches long, rounded, swollen
at the base. Panicles copious,* terminal; main stalks furrowed
and, as well as the patent branches, stout, tinged with red.
Bracteas small. Flowers small. Calyx deeply five-cleft, downy,
spreading. Petals ovate, reflexed, pale yellow, with three orange-
coloured elevated ridges, forming a crest below the middle of the
disk ; these petals arising from a large fleshy five-lobed disk
which surrounds the ovary. Stamens five, of which four are
small and abortive, the third perfect : filaments subulate : anthers
ovate, purple-red. Ovary subglobose, oblique, compressed, gla-
brous: s¢yle subulate, as long as the ovary. Stigma obtuse.
Of the numerous flowers, very few swell and become fruit.
Fruit a drupe as large as a goose’s egg, broadly and obliquely
ovate, subreniform, compressed, dull orange-colour, the remains
of the style forming a little point below the apex. Vu¢ obliquely
oval, compressed, large, clothed with coarser filaments, to which
the juicy flesh adheres pertinaciously. Seed large, reniform.
Cotyledons very large, fleshy: radicle small. W. J. H.
Curr. The fruit of this fine East Indian tree being in high
estimation, it has been introduced into the West Indies and the
tropical parts of America, where it is now much grown, and
in these countries may be considered as taking the place of the
Peach of the temperate zone. . Like all highly-cultivated fruits,
the Mango has its varieties, varying in size and quality, some
being large, fleshy, and fine-flavoured, while others are compared
to a mouthful of tow soaked in turpentine. In the Calcutta
Botanic Garden the variety called Muddah being considered by
Dr. Wallich as one of the best, numbers of grafted plants of
it have been received by us at various times from thence;
for, like other cultivated fruit-trees, the best sorts can only be
perpetuated and increased by grafting, or rather by szarching,
on stocks raised from seeds. Many of the plants, however, have
died shortly after their arrival in this country. Whether this is
owing to the nature of the stocks or to the mode of grafting, is
uncertain, but it does not appear to be through want of care m
* The ‘Gardeners’ Chronicle’ of this day, April 6th, 1850, gives the number
of heads or panicles of flowers on a plant at Sir George Staunton’s, Leigh Park,
namely, 108: the number of flowers on each panicle is on an average 2,100, and the
whole number of flowers was estimated at a quarter of a million, of which (as is
usual even in tropical countries) only a very few ripen fruit. This year our tree
has unquestionably produced an even much greater number of panicles.
their management, for we have known plants when under the
most favourable circumstances and apparently in vigorous health
to dic suddenly above the graft. The Mango is recorded to
have been grown in the hothouses of this country at least 160
years ago; but it is only within the last twenty years that it has
come into notice as a fruit capable of being brought to per-
fection in England. The first, and, we believe, the most suc-
cessful attempt was made by the late Earl of Powis, in his garden
at Walcot, where he had a lofty hothouse 400 feet long and
between thirty and forty wide, constructed for the cultivation
of the Mango and other rare tropical fruits ; but within these few
years we have known it to bear fruit in other gardens. The
plant here figured was sent by Dr. Wallich to these Gardens
some years ago. In the summer of 1848 it was placed in the
Palm-house, where, last year, it bore fifteen fine fruits. It is
growing in a box three feet and a half square, and now forms
a round bushy tree, eight feet across and thirteen feet
high. ‘This spring it has borne a profusion of flowers; and
we now observe some young fruit, but it is not so abundant
as might have been expected from the vast quantity af flowers.
This deficiency of setting may be in some degree ascribed to
its flowering at so early a period of the year, during cold dull
weather, but, we believe, is chiefly owing to the want of im-
pregnation of the ovules, on account of the imperfection of the
stamens. ‘The normal number of the latter is five, but out of
that number only one, generally, bears pollen. As asingle raceme
seldom brings to perfection more than two to four fruits, it may
be inferred that the great profusion of flowers is a provision of |
nature to supply the deficiency of perfect stamens; and being
a hothouse plant and flowering at an early season, it is de-
prived of the agency of bees and other insects, to assist in
conveying the pollen to the stigma. It is, therefore, essential
that some substitute for insects should be resorted to. Brushing
the flowers gently with a camel-hair pencil is probably the best
plan; and, although from the smallness of the flowers the
operation may be tedious, it should be repeatedly done while
the plant is in flower." Judging by the soil in which Mango
plants have been growing when imported, its nature does not
appear to be important for ensuring successful cultivation in India.
Under our cultivation we find the plants thrive in good yellow
loam containing @ little leaf-mould, or other rich vegetable matter,
taking care that it be well drained. An average temperature of
60° in winter will suit them; this should be increased as spring
advances and the plant begins to show symptoms of growth. J. S.

We received this plant at the Royal Gardens of Kew from
Guatemala, by favour of G. Ure Skinner, Esq. It proves quite
new both to our Gardens and to the Herbarium, and where there
is much stove accommodation, it is worth cultivating, for though
the flowers are truly those of a Ragwort, they are of rather large
size, and very fragrant, the scent very much like that of our
garden stock, and the climbing habit is not of very common
occurrence in the Natural Order of Composite. It flowered in
December, trailed against the underside of the glass in the
great stove. The genus Gynorys is assuredly too near Senecio.
* Descr. Root tuberous. Stems very long, climbing, perennial,
branched ; dranches subpellucid and succulent, terete, apparently
showing a disposition to root at the setting on of a branch.

exactly ovate or approaching to lanceolate, acute, wavy at the
margin, of a rather thick and fleshy texture, dark green,

‘» corymbose raceme. TInvolucre cylindrical, with about s1 ; lax,

filaments with a knot or swelling below the summit. Anthers
apiculate. Branches of the style subulate, downy. Achenium

Curt. This is a coarse-growing, soft-wooded, scandent plant,
having a large, thick, fleshy root, of the nature of a tuber. It
grows freely in a mixture of light loam and peat or leaf-mould,
and, by its rapid growth and clean habit, is well adapted for
covering trellis-work. in the hothouse, or it may be trained up
arafter. It is not liable to be attacked by insects, which is a
character much in its favour as a creeper. It increases readily by —
cuttings; but these, on account of their soft, succulent nature,
must not be kept too close, or they will be apt to damp off
before they have had time to produce roots. J. 8.

This pretty shrub has been long in cultivation at the Royal
Gardens of Kew, raised from seeds sent from Van Diemen’s
Land, where it inhabits Mount Wellington. Lately it has been
planted against a wall having an eastern aspect, and has been
found to brave the winters, and to flower copiously in the
summer-months. ‘The flowers are a deep and bright blue, pro-
duced at the end of almost every branchlet.

bushy, very much branched and. subfastigiate, exhibiting two
obscure lines of hairs between the leaves. Leaves copious, rather

single-nerved. Most of the dranchlets are terminated by racemes
of flowers, not many of which are open at one time, though there
is a long succession of them. Calyx about half the length of
the corolla, deeply cut into four nearly equal, linear-lanceolate
segments. Corolla bright and deep purplish-blue, rotate, some-
what two-lipped ; upper lip of one broad oval lobe, lower of
three narrower segments, the middle one the smallest. Stamens
two, shorter than the segments. Capsule elliptical, compressed,
longer than the persistent calyx, two-celled. Seeds obovate,
uncinato-mucronate, attached to a thick funiculus. W. J. H.
Cunt. A neat-growing plant, which, with a few other species,
belongs to a section of Veronica characterized as evergreen
shrubs, having small, closely-set, decussate leaves, and forming
Myrtle-like bushes. The old and well known Veronica decussata
may be viewed as the type of the group. They are natives of
high southern latitudes, being found in Van Diemen’s Land,
New Zealand, Falkland Islands, and Lord Auckland’s and
Campbell’s Islands, in lat. 53°. As might be expected, from
the nature of the climate of these southern lands, the two
species known to us in a living state prove sufficiently hardy
to bear the winter of this climate, when planted in sheltered
situations, and protected during severe frosts. The species
figured is a native of Mount Wellington, in Van Diemen’s Land,
and has been known to us for a number of years. Its neat
habit makes it worthy of being kept in the greenhouse, where
it produces its pretty racemes of light blue flowers in the
spring. It grows readily in light loam and leaf-mould, and is
easily propagated by cuttings, treated in the usual way ; it also
freely produces seeds. J. 8.

A very handsome plant, still rare in our stoves, with fragrant
and very delicate white blossoms, each corolla having its mouth
fringed with a stellated circle of hairs. If the figure of Dr. Sims,
above quoted, be intended for this plant, it is a very defective
representation, both as regards the panicle of flowers and the
foliage, exhibiting of the latter only the two uppermost pairs of
leaves, in fact the floral, or lowest pair of bracteal, leaves, which
differ considerably in form from the cauline ones. Dr. Sims,
indeed, himself alludes to the differences between his plant and
the original species of Roxburgh, which ours undoubtedly repre-
‘sents, as does Dr. Wight’s figure, in his invaluable ‘ Icones,’
and which, indeed, is copied from Roxburgh’s original drawing.
Our plant was communicated to the Royal Gardens by Dr.
Wallich, from the Calcutta Garden, and, hitherto at least, it is
only known from that source, Dr, Roxburgh remarking, “I
have only found this in the Botanic Garden.” It flowered in
the stove in July.
Dzscr. With us this forms a shrud, about six feet high, with
rather straggling, opposite ranches and handsome foliage. Leaves
elliptical-oblong, acute, penninerved, subcoriaceous, glossy, short,
petioled. Stipules ovate, acuminate, deciduous from the older
branches. Floral-leaves one pair, large, placed at the base of
the main peduncle, and resembling the other leaves in con-

Cuxr. With few exceptions, the numerous species of Jvora
are natives of the East Indies, Java, and other islands of the
Indian Ocean ; they require, therefore, to be cultivated in a
warm and moist hothouse. An atmosphere similar to that main-
tained in the Orchideous house will suit them. This is an erect,
slender species, apt to become thin and naked below ; it is,
therefore, necessary occasionally to stop the leading shoots, in
order to make it throw out side-branches. Light loam and
sandy peat-soil suit it, if the pot is well drained. Like the
other well-known species, this increases readily from cuttings,
planted in sand under a bell-glass, and plunged in bottom
heat. J. 9. —

The present is one of three Indian species of plants consti-
tuting the genus Colguhounia of Dr. Wallich, named by that
zealous botanist in compliment to his friend Sir Robert Col-
quhoun, Bart., a gentleman very conversant with the various
branches of Natural History, and who communicated to the
noble Garden of Calcutta many living plants and specimens, and
observations on the botany of Kumaon. The species now before
us was detected by Dr. Wallich in the mountain districts of
Nepal, and was first published in the Linnean Transactions, and
afterwards, with a figure, in the valuable ‘Tentamen Flore
Nepalensis.’ The two other species appeared in the splendid
‘Plante Asiaticae Rariores’ of the same author. This species
has, at first sight, little of the general aspect of a Labiate plant,
but rather of some of the Vitices. It is a tall-growing and sub-
scandent shrub, and flowered in the open air, against a west
wall, in September 1849. The seeds had been many years ago
sent by Dr. Wallich. The flowers are handsome.

frosts with a mat, or some such covermg. A plant in the
Royal Gardens, growing against a west wall, has survived the
last two winters; the upper part of the branches has been
destroyed, but the stout and woody part lower down is un-
injured. It grows luxuriantly during the summer, and in autumn
produces its flowers. It is propagated by cuttings. J. 8.

This and other “scandent” New Zealand species of MMetrosi-
deros do not, in cultivation and confined as they are in pots or
tubs, give any idea of the climbing character attributed to them.
With us the present species has a Myrtle-like habit, four to five
feet high, with rather robust branches and leaves, which only
require to be more acute to be quite like those of a common
Myrtle in shape. Allan Cunningham describes it in New Zea-
land as “a rambling shrub adhering to trees, and by its lateral
roots climbing’ to the summits of the loftiest timber in the forests
of Wangaroa, Bay of Islands.” It appears to be not uncommon
in the Northern Island, and is called by the aborigines 447, and by
the Missionaries Lignwm-Vite, no doubt on account of the hard-
ness of the wood. It requires the protection of a greenhouse i
this country, and flowers in August. age

Curr. This a neat box-leaved evergreen shrub. In its
climbing habit it resembles Metrosideros florida and M. tomen-
tosa, figured at tabs. 4471 and 4488, and, like them, it requires,
in this climate, the protection of the greenhouse during the
winter and spring months. It grows freely if potted in light
loam, and, on account of its slender growth, requires support.
It is easily increased by cuttings placed under a bell-glass. J. 8.

A very handsome and deliciously scented “ garland-flower,”
the flowers a very pure white, bright orange In the disk, and
the anther and filament a very deep orange. It has been long
an inhabitant of our stove, and was sent from India by the late
Dr. Roxburgh. It appears to have escaped the notice of. the
distinguished author of the work on monandrous Scitamimean
plants; though it is nearly allied to two which are figured in
that splendid book, the Hedychiwm flavescens (H. flavum, Bot.
Mag. t. 2378) and Hedychium spicatum. From the former it 1s
at once distinguished by its glabrous leaves, from both by the
larger flowers and the much larger and broader lateral segments,
and by the pure white of the inner segments of the perianth with
the rich orange-colour of the disk or centre. It flowers in the
autumn, and deserves a place in every stove.

upper ones convoluted and almost cylindrical. Zude of the
perianth very long, slender, terete, slightly widening upwards.
Limb of six segments: the three outer ones linear, tawny yellow,
soon withering and reflexed; inner of three very unequal
segments, all pure white with a deep orange disk; the superior

grooved above for the reception of the style: anther \inear-
oblong, recurved, of the same colour as the filament. Stigma
green, protruded a little beyond the anther. WJ. H.
Cunt. The genus Hedychium consists of tropical perennial
plants, characterized by a thick, fleshy, creeping, rhizome-like root,
from which arises an herbaceous, leafy stem, formed of the
sheathing bases of the leaves, and bearmg a terminal head or
long spike of showy flowers. After flowering, the stem dies
down, and the roots.assume a state of rest, remaining so until
again stimulated into action by heat and moisture. When arti-
ficially cultivated, it is therefore desirable, when the plant has
flowered and the stems show symptoms of decay, gradually to
reduce the supply of water. During winter the soil should be
kept just sufficiently moist to prevent the roots from shrivelling :
early in the spring these should be shaken out of the old soil,
and the young and vigorous rhizomes selected for repotting. Fresh
loam mixed with a little rotten dung, or other rich vegetable
manure, suits them, provided it be not such as will become
sour and retentive of water: to guard against this, the pot must
be well drained. In order to start. the plants into growth, they
should be placed in a warm pit, little water being given till they
have made some progress, after which, and during the summer
months, they will require to be freely supplied with it. J. S.

The genus Oderonia is one of the most remarkable of all
Orchideous plants, in the distichous characters of the leaves and
in the usually very dense spikes of minute flowers, not inaptly
resembling those of Myosurus. The name is thus classically
explained by its author, Dr. Lindley : “Ut Oberon, regiolus ille
Dryadeus, Empusarum septentrionalium princeps, in ramos ar
borum equitat, inter folia vultum multiformem abscondens, sic
herbiole nostre, facie non minus mutabiles, in Indie sylvis
latitant v. in curru suo frondoso triumphant.” The present is,
I believe, the largest of the known species, and is a native of
Otaheite, where it was first detected by Sir Joseph Banks (and
whence our living plants were sent us by Mr. Bidwill), of Ceylon
(Macrae), and of Nepal and Silhet, where it was found by
Dr. Buchanan Hamilton and by Dr. Wallich, and where it
flowers in the cold season. With us it first produced its
singular flower-spikes (more like a rat’s than a mouse’s tail)
in January 1850.

briated. Sepals and petals ovate, reflexed, the latter erose or
irregularly serrated. Zip subovate, cucullate and fleshy, and
deep orange-coloured at the base, somewhat four-lobed, downy
within, side-lobes indistinct, terminal lobes forming a bifid apex
with a mucro in the sinus. Column very short, clavate ; stigma
prominent. Anther-case hemispherical, sunk within a cavity at

Curr. Being a native of the warm parts of India, this Orchid
requires to be grown in the warm division of the Orchideous
house. We have found it succeed when attached to a block of
wood suspended near the glass, the plant being in an inclined
position. A damp atmosphere is essential to it; still it appears
to suffer if long exposed to any excess of moisture, especially
during the winter season. J. 8.

side of Java. Mr. Thomas Lobb detected it in the same island,
_ on Mount Salak, and transmitted living plants to the rich
nursery of Messrs. Veitch at Exeter, in whose collection this
handsome species first blossomed in August 1849. It is a
climber, and requires the heat of the stove.

described species, which, with a few exceptions, are natives of
tropical India and the Malayan Islands. hey are soft-wooded,
suffruticose, twining plants, of an epiphytal habit; their leaves
are usually thick and coriaceous. Most of the species inhabit
moist woods, though some grow in exposed places, subject to
great drought during the tropical dry season. This plant is a
native of moist woods in Java, and is described as a strong-
growing species. It requires a temperature suitable for tropical
Orchids, but less moisture, especially during winter. It is
adapted for growing against a back wall or for training up
rafters ; or it may be coiled round a trellis fixed to a pot. Light
peat soil, mixed with a portion of turfy loam, is suitable, pro-
vided it be not such as will become stagnant by an excess of
water. ‘To prevent this, the pot should be well drained with
potsherds, and pieces of charcoal mixed with the soil. It is
propagated by cuttings placed in heat.

An evergreen greenhouse shrub, native of South Africa, east
of the Cape, and extending as far as Delagoa Bay, varying, how-
ever, much in size, in the solitary or racemose flowers, in the size
and serratures of the leaves, which are sometimes sharply serrated,
sometimes nearly if not quite entire. The original authority for
this plant is Plukenet’s very indifferent figure above quoted,
which De Candolle characterized as having “ ovate, acutely den-
ticulated leaves.” Such a form of leaf neither exists in Plukenet’s
plate, nor, have I seen it on any South African Ochna. The
O. arborea of Burchell is said to have “ oval-oblong and nearly
entire leaves,” quite according with O. atro-purpurea. Then an
O. (Diporidium) serrulata was described by Hochstettin from
Port Natal, partly agreeing with ‘our present plant, and which
M. Planchon has rightly referred to it. O. (Divoridium) Nata-
litia of Meisner (also from Port Natal) has no better claim to
be distinct, and is, I believe, intended to be identical with
JUNE lst, 1850.
*
O. serrulata of Hochst. Lastly, the O. (Diporidium) Dela-
goensis of Ecklon and Zeyher, in its character, differs in no respect
from a common form of O. atro-purpurea, and my own specimen
from Delagoa Bay (gathered by Forbes) cannot be distinguished
from it. It is to be feared that many other South African species
have been, in the same way, needlessly multiplied and equally
require the pruning-knife. 0. atro-purpurea derives its name
from the dried state of the plant, when the large persistent
calyces become of a lurid purple-brown, especially when in fruit.
In the living plant, the bright yellow flowers with pale yellow-
green calyx enliven the greenhouse in the month of March.
Dezscr. A rather harsh-looking, rigid shrub, varymg im size
(sometimes, it would appear, from Burchell’s name, tree-like),
- _ with oblong, evergreen /eaves, on short footstalks, quite glabrous,
acute, the margins sometimes almost spinuloso-serrate, generally
moderately serrate, sometimes nearly or quite entire. Mowers
either solitary upon axillary slender petioles, or racemose and
then often terminal. Calyx of five, nearly ovate, concave, pale
sreen sepals, turning red as the fruit ripens, and persistent.
Petals five, obovate, spreading, concave, yellow: these and the
many stamens arise from a long, fleshy, eventually red ¢orus or
gynobase. Anthers golden-yellow, linear, opening at the apex by
two pores. Ovaries five, surrounding a straight style, which
divides at the apex into five short, radiating stigmas. Of the
five ovaries, only one becomes a transversely ovate, large, black,
glossy Jerry upon the large fleshy dorus, now, as well as the
calyx, turned red. (This handsome fruit did not ripen till after
the plate was engraved.) W. J. 7.
Cuxr. A rigid branched shrub,introduced to the Royal Gardens
in 1823, and which, bemg a native of the Cape of Good Hope,
was treated as a greenhouse plant. Although it continued to
maintain a fair degree of vigour (considering its scrub-like habit),
yet it never produced flowers till this season. This was pro-
bably owing to its havmg been placed under different circum-
stances from those to which it had been accustomed. Thinking
it would be benefited by greater warmth during winter, and
having accommodation in the Palm-house, it was placed there
last autumn. The result was, that in April we were agreeably
surprised to see it profusely covered with its pretty, sweet-scented
flowers. Several other plants have flowered similarly for the first
time on being placed in a greater degree of heat, which shows that
with our long-continued low temperature in winter and spring,
and deficiency of bright sunshine in summer (as compared with
the Cape), our usual greenhouse climate is not adapted for the
perfect development of this and other slow-growing Cape and
New Holland plants. J. 8.

A native of Java, where it was detected and whence it was
. sent to Messrs. Veitch of the Nursery, Exeter, by his collector,
Thomas Lobb, who describes it, as it really is, as a handsome
climber, common in the woods at Panarang. Its nearest affinity
is with H. cinnamomifolia, having the same kind of foliage, that
is, with parallel nerves (not penninerved) and flowers of nearly
the same size and shape, but the colour is extremely different in
the two, and in this the corolla is pubescenti-hirsute ; in which
particular, and in the parallel nerves of the leaf, it approaches
the Hoya macrophylla, Bl. Rumpbia, t. 185; but in the latter
the leaf is reticulated between the nerves, the staminal crown
has the leaflets much more acuminated, and the colour of the
flowers is quite different. It flowered copiously in Mr. Veitch’s
stove in September, 1849, when our drawing was made. ‘The
flowers are of a rich purplish-brown. )

Specimens of this fine plant, no less remarkable for the large
size of its flowers than for the deeply-lobed ribs of the stem,
were purchased of Mr. Bridges on his return from Bolivia, where
he had gathered them and other fine species of Cactacee then r
first known in our gardens, in 1844. In 1846, the individual —
which blossomed, and which is here represented, produced purple
flowers ; that which bloomed the following year (1547) bore
white ones. The latter we look upon as identical with the
Echinopsis cristata of Salm-Dyck. The genus Hchinopsis, if
genus it really be, is placed in a distinct tribe, Cereasiree, from
Echinocactus, which is in Echinocactee : the former beng cha- 2
racterized by having the flowers lateral, the tube of the peri- -
JULY Ist, 1850, , 8 ne
gone generally elongated: the latter having. the flowers arising
Jrom the vertex of the stem, and the tube of the perigone generally
short. July has been with us the season of flowering.
Descr. Our largest specimen is about seven inches in dia-
meter, globose, but depressed and rather deeply umbilicated at
the top, full green (not glaucous), somewhat glossy, deeply fur-
rowed, the ribs about 17-18, nearly straight, much compressed,
notched at nearly equal intervals, and thus divided into a num-
ber of very obtuse rounded lobes (crested). Pu/vinult, or collec-
tions of down, in the notches, from which also diverge 10-12
slightly curved, strong, large, and unequal spines, or aculei, the
uppermost one and central one rather the longest and strongest,
all of a dull-brown colour. FVowers very large, 2—4 from a plant,
arising from near the summit and from one of the pulvilli, funnel-
shaped, the fue six inches long, green, bearing numerous acu-
minated scales, fringed with rather copious woolly black hair,
uppermost scales longer, gradually passing into sepals, and those
again into numerous oblong, spreading, rose-coloured petals, ser-
_ rated and mucronate at the point. Stamens numerous, inserted
at the mouth, yellow. Anthers small. Style reaching to the
mouth of the flower, and bearing the numerous long, woolly,
slender rays of the stigma.
Cur. This showy Lichinopsis is a native of Chili, and, like its
Mexican allies, thrives if potted in light loam with a little leaf-
‘mould and a few nodules of lime-rubbish. The latter are for
the purpose of keeping the soil open ; it is also necessary that
the pot should be well drained. In winter, water must be given
very sparingly and the atmosphere of the house should be dry :
the temperature need not exceed 50° during the night, and in
very cold weather it may be allowed to fall 10° lower, provided
a higher temperature be maintained during the day. As the
season advances the plants should receive the full influence of the
increasing warmth of the sun; and during hot weather they will
be benefited by frequent syringeing over-head, which should be
done in the evening : it is, however, necessary to guard against
the soil becoming saturated, for the soft fibrous roots suffer if
they continue in a wet state for any length of time. J. 8S.

A delicately fragrant plant of the Orange family, native of
Silhet and Chittagong, first described by Dr. Roxburgh as a
Limonia, though that accurate botanist speaks with doubt of its
belonging truly to that genus. Dr. Hamilton seems somewhere
to have called it Zwvunga (from its Sanscrit name, “ Luvunga-
luta’’); and Dr. Wight has adopted that appellation, giving, as
we have done, Roxburgh’s excellent account of its fructification
for the generic character. In cultivation, though attaming @
height of nearly twenty feet, it hardly deserves to be called
scandent. Spring is its time of flowering. We owe the posses-
sion of it in our stoves to Dr. Wallich.
Duscr. A tall, lax-growing, but scarcely scandent shrub, with “a
straggling branches, which are glabrous (as is every part of the
plant), terete, bearing a rather long subulate decurved spine im
the axil of the leaf. Leaves alternate, remote, 3-foliolate.
Petiole two to three inches long. Leaflets five to six inches
long, lanceolate, acuminate, entire, penninerved, pellucido-pune-
JULY Ist, 1850.
tate. Mowers axillary, fasciculate, in a dense short raceme,
much resembling those of the Orange, and not less fragrant.
Calyz monophyllous, forming a short cylinder, four-lobed at the
mouth. Petals white, fleshy, oblong, four times as long as the
calyx, at length patent and even reflexed. Stamens eight,
united into a white fleshy ‘ude for nearly their whole length,
the apices free, and bearing each a linear or oblong-acuminate
yellow anther. Pistil as long as the stamens. Ovary seated on
a fleshy torus. Style columnar. Stigma large, globose. W. J. H.
Cur. Although this plant was introduced into the Royal
Gardens in 1823, it never produced flowers till the present year ;
which may be accounted for by its now being allowed greater
freedom of growth in the Palm-house. The kind of soil is not
important: any light loam suits it, so that it be not retentive
of water. As, from its somewhat climbing habit, the plant re-
quires support, it may be set against a pillar or wall of the stove.
It is increased by cuttings, placed in sand under a_bell-glass,
with bottom heat. J. 8.

Ixora salicifolia ; foliis brevissime petiolatis elongato-lanceolatis tenui-acumina-
tis glabris, corymbo amplo denso hemispherico, calycis laciniis ovatis acutis

De Candolle, who, however, only knew this plant from a dried
specimen communicated by Professor Blume, observes well of
it, “Species insignis.” The splendid specimens in a living state
exhibited at the floral exhibitions of Chiswick, and those com-
municated to us for representation in the present work, bear
him out in this eulogium. Nothing can be more beautiful
than the large flame-coloured corymbs of the flowers, or more
graceful than the copious willow-shaped leaves, often more than
a span in length. It is a native of the mountains of Java ; first
noticed there and characterized by Blume, and introduced to
Messrs. Veitch and Son’s Nursery, by their collector, Mr. Thos.
Lobb, from Mount Seribu in the same country. ‘Two varieties
are in cultivation with Messrs. Veitch : the one with the smallest
flowers has them the most deeply coloured. Another /vora 1s
reported to be on sale in this country, quite different from this,
i the name of J. salicifolia, which may be the true plant of
lume.
Descr. An erect, handsome-growing shrub, 2-3 feet high, with
rather closely-placed opposite /eaves, which are borne on extremely
short petioles, almost sessile, narrow-lanceolate, very much acumi-
nated, often a span long, penninerved, entire, glabrous, dark shining
green above, paler beneath. Stipules ovate, acuminate, often
JULY Ist, 1850.
tinged with red. Corymb terminal, large,—when the flowers are
fully expanded, forming a hemispherical head of deeply-coloured,
aurantiaceous flowers, or in var. 8. almost crimson. ‘The ovary
is short, hemispherical, crowned with the four small, ovate, acute
lobes of the calyx. Corolla with a very long, slender, almost
filiform ‘vse: the Jimd of four, ovate or lanceolate-ovate, hori-
zontally spreading, acute Jobes. Stamens small, inserted at the
mouth of the tube. S#y/e scarcely exserted. Stigma three-lobed.
Curr. This showy /zora, an abundant flowerer, even when
only six inches high, requires a warm and moist stove, and a
soil composed of about half loam and half peat, with a portion
of sharp sand. In order to form a handsome plant, a young
healthy one should be selected, and freely encouraged into quick
growth by placing it in bottom-heat. As it increases in size it
must be shifted into larger pots, which should be well drained,
so that water and syringeing may be freely administered during
the summer-season without the risk of the soil becoming satu-
rated. It is increased by cuttings, which should be planted in
sand under a bell-glass, and placed in bottom-heat. /. 8.

At the first, and truly splendid, Exhibition of flowers at the
Chiswick Gardens of the present year (1850), few plants
excited greater attention among the visitors most distinguished
for taste and judgment, than the one here figured, from the
nursery of Messrs. Veitch, of Exeter. Many excelled it in splen-
dour ; but the delicacy of form and colour of the flowers (white
with a deep pink eye), and probably their resemblance to the
favourite Jessamine (some compared. them to the equally favourite
Stephanotis), attracted general notice. So unlike, indeed, are
they to the ordinary form of Rhododendron blossoms, that the
‘Gardeners’ Chronicle,’ in recounting the prizes of the day,
seemed to imply that this was probably no Rhododendron
at all! If the author of the paragraph had referred to the
figure of the Indian R. Anthopogon, figured in the * Botanical
Magazine,’ Tab. 3947, he would see there as truly a salver-
shaped corolla, and nearly as regular a limb : the more remars-
able character is the great length and straightness of the tube.
It is a native of Mount Ophir, Malacca ; elev. 5000 feet ; having
been there discovered by Mr. Thomas Lobb, and transmitted to
the nursery of Messrs. Veitch. It seems a ready flowerer. The
specimen here figured was drawn in September of 1849, and still
finer flowering plants were shown at the May Exhibition at
Chiswick, in 1850. :
Dzscr. A small shrub, as reared by Messrs. Veitch, one foot

and a half high, the dranches bare of leaves below, and knotted
where they had been inserted. Leaves crowded towards the
upper part of the branches, lowermost ones subverticillate, on
short petioles, obovato-oblong, rather acute, glabrous, nearly co-
riaceous. Uméel terminal, many-flowered. Peduncles 1-flowered,
short, with small reddish dracteas at the base, and, as well as
the very small, shallow, obscurely 5-lobed calyx, lepidote.
Corolla salver-shaped, white, slightly tinged with rose below
the limb; the fwbe two inches long, straight, scarcely gibbous
at the base: the /imd spreading, of five obovate wavy lobes, almost
exactly equal. Stamens 10. Filaments filiform, downy, as Jong
as the tube. Anthers red (forming a red eye, as seen at the
mouth of the white corolla). Ovary oblong-cylindrical, lepidote,
5-celled, glandular at the base. S*y/e rather shorter than the
stamens, filiform, downy. Stigma dilated, obtuse, green.
Curr. Our only knowledge of this very distinct and singular
species of Rhododendron is from having seen it exhibited during
the past month at the London flower-shows. Judging from its
habit and native locality, we infer that it will require to be treated
as_a warm greenhouse plant, and thrive in a sandy peat
soil. J. 8.

(not Linn.) ;
A rare and remarkably fine species of Svipperwort, figured
by Ruiz and Payon, as the C. perfoliata of Linneus, from
the original plant detected by them at Chincao and Mufa in
the Andes of Peru. By Mr. Mathews it was discovered at
Chacapoyas. We are indebted for the specimen here repre-
sented, as well as for a living plant, to Messrs. Lucombe,
Pince, & Co., of the Exeter Nursery, who observe, that when
bedded out in the summer it makes a very striking appearance,
with its noble and rather deep yellow flowers and ample foliage.
Like the Calceolarias in general, it produces a long succession of
blossoms, which renders the plant so eminently suited to the
flower-border.
Drscr. Root perennial. Stem herbaceous, one and a half to
two feet and more high, a good deal branched, herbaceous, suc-
culent, terete or but slightly angled, copiously clothed with
patent or slightly deflexed, hairs, green, sometimes tinged with
purple and slightly viscose. Leaves rather large, often more
than a span long, opposite and perfoliate with the very broadly
winged base of the petiole ; the d/ade ovate, acute or acuminate,
often truncate or cordate at the base; the surface wrinkled with
JuLy Ist, 1850.
copious veins, the margin, doubly toothed, often lobed to-
wards the base, downy above, pale, almost white, and some-
what woolly beneath ; the wing of the petiole, very broad at the
base, is much toothed and foliaceous, and is decurrent, as it were,
from the base of the blade of the leaf. Panicle ample. Mowers
very large. Calyx of four deep, broadly ovate, acuminate,
spreading, slightly dentate, hairy /odes, measuring two inches
across. Corolla with upper lip inflexed, much shorter than the
calyx ; lower lip almost orbicular, very large, folded against the
upper lip, but not so much as to exclude from view the deep
blood-coloured spots in the inside.
Curr. This distinct species is of robust habit, and, like others
of the genus, grows freely in the open border during the summer,
but requires the protection of a pit or greenhouse during the
winter. We have hardly yet had the opportunity of testing its
merits as a bedding plant, but we fear its tall and rude growth
may be somewhat against it for that purpose. Its handsome
flowers make it well worthy of being grown as a show-plant for
the greenhouse. It is readily increased by cuttings, which should
be taken off about the end of the summer and placed under a
hand-glass in a moderately warm place. /. S.

A handsome small tree, discovered by Dombey in Brazil, and
since found by St. Hilaire and others in the province of Rio de
Janeiro, where, we. are informed, it is also cultivated and the
fruit brought to market, and sold under the name of Grumi-
chama. It is handsome in its foliage and in its copious snowy
flowers, which latter are remarkable for having their origin upon
the lower portions of young terminal branches, or, 12 other
words, upon partially developed leaf-buds, springing from the
axils of opposite scales below the leafy portion. In this state
the young leaves are deep purple-brown, contrasting prettily.

concave scales: from one or two of the uppermost pairs of these
scales the peduncles appear, an inch and a half or two inches
long, single-flowered. Calya with the tube oval-globose, having
a few opposite hairs at the base: /imd of four large, spreading,

Curr. This species is an old inhabitant of the Royal Gardens.
Having been kept for many years in a small pot it never pro-
duced flowers ; but on being removed into the Palm-house, and
shifted into a large pot, it grew vigorously, and in the spring of
this year produced a profusion of flowers. It is now a handsome
_ Laurel-hike bush, six feet high. Light loam, mixed with a
small quantity of leaf-mould, suits it ; and, as it is what may be
termed a thirsty plant, it requires to be well supplied with water
during the spring and summer months. It increases by cuttings
; placed under a bell-glass, and plunged in bottom-heat. J. S.

The Royal Gardens of Kew are indebted to our excellent
friend Mr. Bidwill for specimens of this rare Dendrobium, which
he detected in Australia, we presume in the interior, and which
were sent to Europe in 1844. Dr. Lindley refers it to a group
of Dendrobium, corresponding to the genus Desmotrichum of
Blume, especially characterized as having “root-shaped, jointed,
bulbiferous stems,” but which he does not consider to be pos-
sessed of characters sufficient to constitute a genus.
Descr. Pseudo-bulbs clustered, jointed, oblong, attenuated
upwards into a long stem-like neck, bearing two to four oblong
subcoriaceous recurved eaves, emarginate at the apex. From
the centre of these leaves the peduncle arises, about as long as the
pseudo-bulb and leaves, and bearing from three to six flowers —
in one specimen. Ovary clavate, pedunculiform below. Sepals
purple, ovate, the two lateral ones connate and decurrent with
the base of the column into a long blunt or retuse spur, pale- —
coloured at the back, yellow at the apex. Petals much smaller —
than the sepals, of the same colour. Lip three-lobed, attenuated :
at the base and articulated on the apex of the spur, white
streaked with purple and having three yellow lamina on the
aveust Ist, 1850.

disc, side-lobes acute, terminal one nearly rhomboid, apiculate.

Cutt. This species of Dendrobium is a native of New South
Wales, beyond the tropic ; it does not, therefore, require the high
degree of temperature necessary for the cultivation of the nume-
rous species which are natives of tropical Asia. It is epiphytal
on trees, and is subject to long droughts. It thrives if potted
in turfy peat, well-drained, and kept in the cool division of the
Orchideous house. /. 8.

Discovered by the late Mr. Baxter at King George’s Sound,
from whose specimens Mr. Brown described the species in the
Supplement of his ‘ Prodromus,’ and from whose specimens also
the figure in ‘ Icones Plantarum,’ above quoted, was taken. At
that time only fruit-bearing plants were detected. Mr.
Drummond has also found flowering individuals at the Swan
River Settlement, and has sent seeds, from flowering plants of —
which our figure was taken at the Royal Gardens, in April
1850. Professor Meisner confounded H. cucullata with it in
the ‘Plante Preissiane :—probably its nearest affinity is the
noble H. Victoria of Mr. Drummond’s Journal, given in a late
volume of the ‘ London Journal of Botany,’ and of which there
are living plants also at Kew.
Drscr. Our plants of this constitute erect shrubs, four to five
feet high, the dranches terete, pale brown, very villous. Leaves
coriaceous, slightly villous only near the base below, cordate, or
reniform-cordate, sessile, large, spreading, concave, more so I
the upper leaves, repand and waved and rather minutely toothed
at the margin, glaucous green, distinctly reticulated both above
and below. From the axils of the upper leaves the flowers ap-
pear in copious clusters : at first surrounded by imbricated deci-
duous bracts. Pedicels clavate, hairy at the base. Perianth red,
of four unequal linear sepals, glabrous, the apex of each spathu-
late and bearing the anther in the hollow of the interior. Ovary
linear. Style very long, twice as long as the longest sepals.
Stigma conical-acuminate. Fruit (represented in the ‘ Icones
Plantarum’ above quoted) clustered, about an inch long, ovate,
acuminated, woody, splitting into two thick, semiovate, woody
valves, gibbous and unequal on the outside. WV. J. H.

Cunr. Before the introduction and high state of cultivation of
the splendid flowering plants now annually exhibited in the
vicinity of London, it was customary to estimate the value of
public and private collections by the number and rarity of
the species, without regard to the circumstance of their pro-
ducing fine flowers. Perhaps no plants were in higher repute
than those of the family to which this belongs, as is amply
shown by the early volumes of the Botanical Magazine.
Within the last twenty or thirty years, however, the cultivation
of Proteacee has declined; the species have gradually dis-
appeared from most of the private collections around London ;
and but few nurserymen now take interest in them. This change
may be partly owing to the supposed difficulty of preserving
them, for under certain circumstances the plants suddenly die,
_ even when in vigorous health. In the Royal Gardens Proteaceae
have maintained their place, more especially those that are
natives of Australia ; and as there are some at this time between
forty and fifty years of age, and others of a large size half that
age, it may be inferred that Proteacew are not so short-lived in
a state of cultivation as they are generally supposed to be.
Within our recollection it was the common practice to grow
them in some kind of light soil, usually peat. ‘The hygrometric
condition of such soil is easily affected by changes of the sur-
rounding atmosphere ; becoming quickly dry during hot weather,
and apt to become sodden with moisture in winter, and the
spongioles or rootlets of Proteacee are very sensitive to either
extreme ; the use of light soil, therefore, in our opinion, accounts
for the frequent sudden death of plants of this kind. In the
Botanical Magazine for 1836, at Tab, 3500, we have given our
views on the cultivation of Proteaceae. We use good yellow
loam, to which, for small plants, we add a little sharp sand. In
shifting or repotting a plant we make it a rule to keep the ball
of roots a little elevated above the surface of the new mould, to
prevent any superabundance of water from lodging round the
base of the stem. In the winter care must be taken’to give no
more water than is required to keep the soil moderately moist,
but In summer water may be given freely in the evening or
early in the morning. It is important that the plants should be
80 placed that the sun’s rays do not strike the sides of the pot.
The species here figured, being a native of the Swan River
Colony, requires to be treated as a greenhouse plant. It does not
readily propagate by cuttings, but may be increased by grafting
on any of the more common free-growing species. Imported
seeds germinate freely. J. 8.

for 1850, under the name of 8. ciliatum. ‘That plant, however,
faithfully represented in our ‘Tab. 3583, is a very different,
though nearly allied species, with the panicle compound, and,
as well as the scaly scape, clothed with long patent hairs, tipped
with dark-coloured viscid glands, and with flowers not hall the
size of the present one. Sonder describes this as having the
labellum inappendiculate, and perhaps he alludes to another
plant; but the gland would probably escape his notice in the
dried specimen.
Descr. Root perennial, dividing at the crown so as to bear
copious tufts of densely imbricated, spreading, rosulate, linear
leaves, slightly incurved, yellow-green tinged with purple, tapering
at the base, acute at the point, and there bearing a long hair or
bristle; the margins especially, ciliato-scabrous. Scapes one or

outside of the corolla, are copious, short, glandular hairs. a-
ceme, in our specimens, entirely simple. Pedicels with two

Cur. This belongs to an extensive genus, comprising about
- one hundred described species, which, with two or three excep-
tions, are all natives of New Holland and Van Diemen’s Land,
the greater number being found on the western extratropical
coast of New Holland. As regards their habit and places of
growth, they may be compared to species of several British
genera; such as Statice, Jasione, Phyteuma, Plantago, Samolus,—
and even Drosera. This species is a native of Swan River, and
must be treated as a greenhouse plant; it requires no more
artificial heat than is necessary to protect it from frost, and, like
many other small plants, it will thrive best when kept in a cool
pit or frame; but care must be taken that it does not suffer
from damp in winter. Light peat soil is found to suit it. J. 8.

_ CAMPYLOBOTRYS discolor.
~ Campytosorrys discolor. (Hort. Paris.)
Under the name here preserved we have received at the Royal
Gardens of Kew, from the Paris Jardin des Plantes, the very
beautiful plant now represented, accompanied by the informa-
tion that it is a native of Bahia; while in a Belgian nursery
catalogue it stands as a native of Mexico. We nowhere find
such a name taken up by scientific botanists ; and, on the other
hand, we are unable to refer it satisfactorily to any published
genus. It is treated as a stove-plant, and is remarkable for
the lurid green yet satiny surface or velvety gloss of the a |
side of the leaves, and the rich red-purple tints of the branches _
and under side of the foliage, and the still more pronounced
red colour of the peduncles and flowers and teeth of the
calyx. We have never seen the fruit. W. J. H. he Rs.

Jardin des Plantes at Paris, and have no further knowledge re- _
specting it, except that it “came from Bahia.” We have treated
it as a stove plant, and find that it grows freely if potted in
light peat-soil, with a little leaf-mould. The pot is plunged in
a bed of moist Sphagnum sods, on a front shelf, where, with
other coloured and variegated-leaved plants, it forms one of an
interesting group. It produces lateral branches, which, taken
off as cuttings, root readily when placed under a bell-glass and
treated in the usual way. J. S.

A very pretty creeping Gesneraceous stove-plant, imported
from the Organ Mountains, Brazil, by Messrs. Backhouse of the
York Nursery, and obligingly sent by them in April 1850.
There can be little doubt of the plant being identical with the
Hypocyrta described and figured by Dr. von Martius, /.c., though ©
his figure, made probably from dried specimens shrunk in the
act of drying, gives the appearance of a more s/ender plant than
ours is :—even ours has a much less robust habit than the other
species of Hypocyrta described by Von Martius. That author
constitutes two divisions of his five species: the one “ Codo-
nanthe, corolle tubo subcampanulato inque latere antico parum
ventricosiore, limbo latiusculo,” and “ Oncogastra, tubo deorsum
valde gibboso-ventricoso, limbo breviter dentato erecto.” Our
plant belongs to the first section. ks

creeping, although, as Martius describes it, sometimes bearing
ascending shoots. Stem branched, terete, purplish-brown,

slightly concave above, pale and often blotched with red and
convex beneath. Flowers on short red peduncles, solitary or in
pairs, single-flowered. Calyx of five, deep, linear-lanceolate
segments, red at the base. Corolla moderately large, cream-
white, spotted with orange on the underside of the tube within,
campanulate-infundibuliform : tube decurved, and again curved -
upward at the mouth ; /imé of five, nearly equal, rounded seg-
ments. Stamens shorter than the tube. Anthers united in
pairs. Ovary ovate, hairy, with a large gland at the base of the
back. Sfyle shorter than the stamens : stigma obtuse. WV. J. H.
Curr. A soft-wooded suffruticose plant, of a trailing scandent
habit, emitting roots from below the axils of the leaves, and
growing as an epiphyte on trees in the moist forests of Tropical
America. It should be kept in such an atmosphere as that
appropriate for the cultivation of tropical Orchids, and, if there
is sufficient accommodation, it may be allowed to grow in a
natural manner over any elevated surface, covered with turfy
sods, kept moist ; or may be planted in a pot or basket filled
with loose turfy soil and suspended from the roof. J. S.

One of the many fine things sent from Java to Messrs. Veitch
of Exeter, by their collector, Mr. Thomas Lobb. “ How fine
a plant of its kind this is,” says Dr. Lindley, in the Bot. Reg.
l. c., “ may be surmised, by its having been taken for a Calogyne :
the flowers are full four inches across, yellow, shaded with
cinnamon, spotted with light brown, and speckled outside with
brown-purple :—we know of no species of the genus comparable
to it for beauty.” Our drawing was made from the plant of
Messrs. Veitch, after it had gratified the public at the May
Exhibition of the Chiswick Gardens for 1850.
Descr. Pseudo-bulbs ovate, smooth, green, nearly as large
as a pigeon’s egg, partially sheathed with a ragged membrane,

brown, shorter than the leaf; its base sheathed with imbricated,
convex, spotted scales. Mowers large, solitary, spreading.
Sepals lanceolate, acuminated, deep yellow, the upper one
externally marked with purple spots running in lines; the
lateral ones falcate, streaked and clouded with purple. Petals
resembling the upper sepal, but smaller and streaked with
purple lines, reflexo-patent. Zip cordato-ovate, eR

Cuxr. This, like the rest of the numerous species of Bolbo-
phyllum, is a tropical epiphyte, and requires to be kept in the
warm division of the Orchid-house. It grows and flowers
freely on a block of wood, suspended from the roof of the
house, and having a piece of Sphagnum-moss attached. In
winter an excess of moisture, either in the atmosphere of the
house or in the moss or block of wood, is prejudicial ;
and in summer the plant must be shaded from the mid-
day sun.

MeEDINILLA bracteata. Hort. Veitch, (non Blume.)
This fine plant, truly deserving the name of magnifica, when
first exhibited by Messrs. Veitch at the early spring meeting of
the Horticultural Society (where a large medal was awarded to
it), bore the name of I. bracteata, given to it probably by
Mr. Veitch, or by his collector Mr. Thomas Lobb, under an
impression that it would prove to be the plant so named of
Java, by Blume, who afterwards, however, referred that plant to
a new genus, Dactyliote. A slight comparison, however, with
the description may show that it has nothing to do with that
plant, and it is by mistake that it is stated by Lindley and
Paxton to be a native of Java at all. The present species was
detected at Manilla, and sent thence to Messrs. Veitch’s nursery,
and proves to be one of the most showy and ornamental plants
that has ever been imported. We thought highly of Medinilla
speciosa (vide supra, Tab. 4321); but the leaves are here much
finer (a foot long), the panicle a foot and a half long, the flowers
far more numerous, and the noble and delicately-coloured bracts
add greatly to the charms of the shrub. Its most beautiful
state is, perhaps, before the full perfection of the flowers, when
the large imbricated bracts begin to separate, and allow the buds
to be partially seen. As the expansion of the blossoms advances,
the upper bracts fall off, but the lower ones remain and become

reflexed. It is a stove-plant, and Messrs. Veitch describe it as
of easy culture, loving moisture when in a state of growth, and
flowering copiously when only two or three feet high.
Descr. Evergreen, erect (may it not eventually become
scandent ?), everywhere glabrous, with dranches compressed
and four-winged, bearing tufts of bristles at the joints. Leaves
very large, opposite, coriaceous, broadly oblong, cordate and
semiamplexicaul at the base, triple-nerved below the middle,
and the rest penninerved, dark green above, pale beneath.
Panicle \arge, terminal, eighteen inches and more long, when in
bud the whole clothed with densely imbricated, large, rose-
coloured dracteas: these latter are gradually deciduous, the
lower and larger ones remaining and becoming reflexed ; the
lowermost tinged with green. Branches of the panicle whorled,
much divided. owers very abundant, deep rose-colour, in
form and structure almost exactly resembling those of J7/. spe-
ciosa, already referred to. W. J. H. 3
Cuxr. This singular plant, being a native of the Philippines,
requires to be treated as a stove-plant. It grows and flowers
freely if planted in a mixture of loam and peat. The pots
must be well drained, so as to allow water to be liberally given
during the season of growth, without the risk of the soil
becoming sodden; it should also be frequently syringed. It
is readily increased by cuttings placed under a bell-glass, and
plunged in bottom heat. J. 8.

From the rich collection of Messrs. Lucombe, Pince, and Co.,
Exeter Nursery, who received it, and have cultivated 1t in the
stove, under the name of “ Portlandia grandifiora, fine variety ;
but they very justly remark to me, that both in its foliage and
in the flowers it differs considerably from that species, as may
be at once seen by comparing our present figure with the true
P. grandiflora, given at Tab. 286 of the ‘ Botanical Magazine.
“ Tt flowers,” say Messrs. Lucombe and Pince, “in avery dwarf
state, and is almost always in blossom,” an observation confirmed -
by the continual flowering, during the summer of 1849, of a
small plant not more than a foot and a half high, which they were
so good as to send to the Royal Gardens, and from which owr
figure was taken in July 1850.

erect, branched, glabrous. Leaves opposite, nearly sessile,

green, everywhere entire, penninerved. Stipules broadly tri-
angular, obtuse. Pedicels very short, axillary, solitary, often

revolute. Stamen and style included. Filaments downy in their
lower half. Anthers linear. Stigma deeply bipartite; the
branches linear. W. J. #7.
Cuxr. A tropical shrub, with fine glossy leaves and showy
white flowers, which latter are produced on plants when not
more than two feet in height. It is, therefore, worthy of a
place in every collection of woody stove-plants. It grows freely
im a mixture of loam and leaf-mould or peat soil. It must be
kept in a moist tropical stove, the necessary precautions of
watering and shading during clear summer sunshine being
carefully attended to. It is propagated by cuttings placed
under a bell-glass, and plunged in moist bottom-heat. J. 8.

The very pretty Water-Lily, here represented, was obligingly
communicated from the Tropical Aquarium of E. Silvester, Esq.,
the successful cultivator of Mympheacee at North Hall, Chorley, —
Lancashire, in August 1850. It was received by him from
Chatsworth, but it appears to have been imported by Lord —
Derby, from the River Gambia, to Knowsley Gardens. The “
long acuminated points of the leaves, and the viviparous axils
of the lobes, are its most striking character ; and in these two
important particulars, as well as in some others, this species:
agrees with a Senegambian one to which I have referred it, viZ.,
the V. micrantha of Guillemin and Perottet. If it does not
coincide in all points—such as the number of stigmatic rays—
it must be remembered that aquatic plants are very variable,
and we must not lay too much stress on differences of that kind.
It is true the authors describe the flowers as blue, or pale blue,
but native authentic specimens in my herbarium appear to ~
be white.
Descr. The Petioles and Scapes appear to be both much
elongated (influenced, probably, by the depth of water in sion
they have grown), tinged with red, terete, glabrous. Leaves a
quite glabrous, elliptic, rotundate in outline, partly entire, see
irregularly toothed, the lower portion cut into two deep, muc
acuminated, moderately spreading lobes, at the sinus of which,

as it were from the top of the petiole, gemma, or little bulbs,
appear and develope themselves into young plants! The under-
side of the leaf is pale green, tinged with pale purplish-brown
and minutely dotted. 2owers smaller than our common White
Water-Lily, the size of WV. stellata. Calyw of four sepals, pale
yellow-green, and the numerous white or whitish petals are lan-
ceolate and very acute, not gradually passing into stamens, though
the outer stamens are more petaloid than the inner ones. Stigma
in our plant with eleven incurved obtuse yellow rays. W. J. H.
Curt. This Water-Lily, being a native of Western Africa,
requires to be grown in a warm stove, and will thrive if treated
in the way mentioned for Nymphaea ampla, at Tab. 4469. This
species is remarkable from the circumstance of its producing
a viviparous bud at the sinus of the leaf on the upper surface,
which bud ultimately becomes a separate plant. J. 8.

Cocco.LosBa macrantha, Desf. (Steud. Nomencl. Bot.)
One of the most striking plants which has flowered in the
great stove of the Royal Gardens during the year 1850, is that
here represented, of which plants were long received from
Paris, under the name of Coccoloba macrophylla of Desfontaines,
a name which we can find nowhere published save in the two
editions of Steudel’s valuable Nomenclator; but there its na-
tive locality is marked as unknown. ‘This is probably South
America, where the maximum of the species are to be found.
The name is far from appropriate, for the leaves yield greatly
in size to the C. pubescens (Bot. Mag. t. 3166), the latter being
three or four times the size of the present. Our plant, however,
equals the pubescens in height (our largest plant being twenty-
three feet high) : it tapers gracefully upwards, is leafy all the way
up, and terminated at the top by a dense compact thick club-
shaped raceme of flowers, of which the rachis, pedicels, and flowers
SEPTEMBER Ist, 1850.
are of the richest scarlet. This raceme continued in great beauty
for two months, and when looked down upon from the gallery
above, backed as it was by dark-green foliage, it presented a
beautiful object. The drawing was made in July.
Descr. A subarboreous plant, with simple or scarcely divided,
sulcated, erect stems, twenty to thirty feet high; leafy from
below to the top. eaves alternate, distant, dark green, a foot
or more long, horizontally patent, cordato-ovate, semiamplexi-
caul, sessile, acute or acuminate, strongly nerved, wrinkled and
reticulated, subbullate. Raceme terminal, subsessile, erect, two
or more feet long, the flowers so numerous and dense that they
appear to form a compact cylindrical spike ; every part of a rich
scarlet colour, save the stigmas, which are yellow. Pedicels
in clusters. Perianth articulated on the pedicel; éwbe fumnel- —
shaped; mb cut into 4-6 rounded concave lobes. Stamens
8—12, monadelphous below. Anthers cordate, subapiculate. Ovary
oblong-rhomboid, triquetrous, red. Styles 3. Stigmas capitate.
Fruit baccate, red. W. J. H.
Cutt. The genera Coccoloba, Triplaris, and Podoptera are
the tropical representatives of the Order Polygonee, and may
be viewed as examples of the genera Rheum, Rumex, and
Polygonum, taking the form of trees or shrubs. They are natives
of the West Indies and tropical America, and often attain a
considerable height. They generally have large entire coriaceous
leaves, and bear spikes or racemes of flowers, succeeded by
bunches of berry-like fruit, which, as many of the species inhabit
the shores, have given rise to the English name, ‘ sea-side grapes.’
‘The present species appears to be a tall-growing tree: our plant
is now ten feet high, and, with its broad stiff leaves and long
erect spike of red flowers, has a very striking appearance. It
requires to be kept in the stove, grows freely in light loam,
and may be increased by cuttings treated in the usual way for
tropical plants of like nature. J. 8.

which was from Messrs. Lucombe, Pince, and: Co., who sent a
flowering specimen in June 1850, from a plant they imported
from Sierra Leone. The same species has since flowered in the
stove of the Royal Gardens of Kew, our plant having been raised
from seed from the same country. Imperfect as are the figure
and description of Spathodea levis in Palisot de Beauvois above
quoted, Iam yet of opinion I am correct in referring it to that
plant. If by the term “laevis” applied to the species it is
meant that there are no glands on the calyx or corolla, I may
Observe, that however obscure on the dried specimens (from
which M. de Beauvois’ drawing and character were derived), they
are apparent enough on the living plant.

Descr. Our plant of the Spathodea levis is sixteen feet high ;
but it flowers when much smaller with Messrs. Lucombe and
Pince. Its stem is woody, but soft. The /eaves are alternate,
except those below the inflorescence, which are often ternately

whorled, all of them impari-pmnate, with from four to six pair
of opposite, ovate, acuminate, coarsely serrated, glabrous, sessile
leaflets. Panicle terminal, corymbose, with numerous large
flowers. Calyx green, tipped with red, spathaceous, subcylin-
drical, close-pressed to the tube of the calyx, split open more
than half-way down on one side, striated, with several dark-
coloured glands near thes base, irregularly toothed at the apex :
teeth small, three to five. Corolla campanulato-infundibuliform,
white, delicately spotted and streaked with rose ; tube widening
upwards : limb obscurely two-lipped ; upper lip of two rounded
lobes ; lower of three similar ones, but, larger and more spread-
ing; all slightly waved. Stamens four with rudiment of fifth.
Style included. Anthers oval. Ovary cylindrical, narrow, arising
from a five-lobed gland or disk. Style geniculated on the ovary.
Stigma bilamellate. W. J. H.
Cuxr. This is a tropical tree of robust growth, requiring the
temperature of the stove, and growing freely in light loam. It
is propagated by cuttings planted under a bell-glass in white
sand, and plunged in bottom-heat. /. 8.

foliis glabris lineari-subulatis setaceo-mucronatis, scapis vel pedunculis
terminalibus nudis superne paniculaque glanduloso-pilosis, corollis luteis
aurantiaco-pictis, labello utrinque appendiculato, ovario cylindraceo-elongato.
Sryzrprum mucronifolium. Sond. in Plant. Preiss. v. 1. p. 383.
Raised by Messrs. Lucombe and Pince, from Swan River seeds,
and communicated to us by that firm under the name here
adopted, and by which is doubtless intended the plant so called
by Sonder, with which, however, it does not wholly agree, for
neither is the labellum in our plant “inappendiculate,” nor can
the leaves be said to be “radical.” The first character is,
indeed, easily overlooked in the dried plant, from which Sonder
was likely to have drawn up his description ; and with regard
to the latter, tufted rosules of apparently radical leaves do, in
several Stylidia, elongate into real leafy stems or branches.
Again, the nearest natural allies of our plant are unquestionably
S. ciliatum, Lindl. (Bot. Mag. t. 3883), and 8. saxifragoides,
Lindl. (Bot. Mag. t. 4529); but Sonder has separated them by
nearly thirty species ; the two just mentioned belonging to the
section Tolypangium, Endl., our present plant to the § Nitran-
gium, Endl.:—two groups only distinguishable by the more or
less elongated ovary or capsule—assuredly a very artificial cha-
racter. Our species is very pretty and produces its copious
bright tufts of flowers in August.
Descr. Roots wiry, brown. Stems in our plant tufted, two
to three inches long, copiously leafy. Zeaves glabrous, patent, —
linear-subulate, broader at the base, tipped at the point with a
setaceous mucro. Peduacles, rather than scapes, terminal, soli-
tary on each branch, a span high, above, and the pedicels

and calyx clothed with slender hairs tipped with glands,
so delicate as to be scarcely visible to the naked eye. Panicle
subrotund or oval, many-flowered, rather compact. Corolla
rather bright yellow, with zigzag orange lines round the mouth.
Ovary or capsule much elongated, slender, cylindrical. W. J. H.
Cuxr. The present species of Sty/idium, being analogous in habit
to S. saxifragoides, figured at Tab. 4529, requires the same treat-
ment as there mentioned. In summer these small weak plants
should be placed in a situation where they may be maintained
in a moderately moist state, without having daily recourse to
the water-pot; and in winter they should be placed in a dry
airy place, taking care in damp weather that no water lodges
amongst the fascicles of leaves, for when this happens the plant
is liable to be destroyed. J. 8. . |

Gorponta Javanica. Hort. Rollison.
Our Garden is indebted to Messrs. Rollison, of Tooting, for
the plant of which a specimen is here figured ; and, not being
able to discover any published species to which it can be re-
ferred, we retain Messrs. Rollison’s name. It was discovered
by their collector in Java, probably in the mountains; and
has much the general habit of Thea or Camellia, when its
blossoms appear, in August and September.
Descr. Our plant is about two feet high, branched, and
generally glabrous. Branches terete. Leaves alternate, ellip-
tical-lanceolate, coriaceous, evergreen, acuminated, entire, pemni-
nerved, below tapering into a short petiole. Peduncles solitary,
axillary, single-flowered, from the base of most of the upper

leaves, and shorter than the leaves, erect, bearing two or three
deciduous, spathulate, green bracteas below the calyx. Calyx
of five very concave, rotundato-elliptical, erect, slightly hairy
sepals. Petals five, obovate, white, spreading, obliquely twisted.
Stamens very numerous. Ovary globose, obscurely five-lobed,
five-celled, hairy. Style columnar. Stigma peltate, of five, large,
rounded, somewhat leafy, rays or lobes, the centre umbilicated.
Fruit the size of a large garden-pea, globose, depressed at the
top, half five-valved, woody. W. J. .
Cunr. A neat evergreen tea-like shrub, a native of Java,
which flowers freely when of small size. Not being aware of
its locality, we have treated it as a stove plant; but, judging
from the nature of many of its allies, we may be right in
presuming that it is from an elevated and temperate region,
and if so, it would probably succeed in a warm greenhouse. It
grows readily in loam and peat or leaf-mould, and is easily
increased by cuttings. J. 8.

PITCAIRNIA Jacksont.
Mr. Jackson's Piteairnia.

Gen. Char. (Vide supra, Tas. 4241.)
PircatRNia Jacksoni ; foliis subulato-ensiformibus carinatis subtus albo-furfu-
raceis supra medium spinoso-serratis, scapo simplici, pedicellis patentibus
calycibusque farinosis, sepalis obtusis, corollee curvate petalis lineari-
oblongis subtortis longitudine staminum intus ‘squamosis squama bifida
_ serrata, stigmatibus ciliatis.
This very handsome Pitearrnia was flowered by Mr. Jackson, .
the eminent nurseryman of Kingston, Surrey, who imported it
in a very young state, among tufts of Orchideous plants from
Guatemala. Its nearest affinity is probably with P. bromelia-
folia (Bot. Mag. t. 824, where the differences will be at once
apparent) and equally belongs to the division “petalis basi
squama instructis.” Among them we find no species with
which this accords, and hence we name it in compliment to
Mr. Jackson. It is, as may be presumed, a stove-plant, and
flowers in the summer months, making a striking appearance ~
with its copious large scarlet flowers.
Descr. Root of many tufted fibres. Plant throwing up
many suckers from the base. Leaves a foot and more long,
subulato-ensiform, striated, attenuated above and below, upper
half only spinuloso-serrated, the rest entire, above dark green
and naked, below clothed with a whitish floccose or pulverulent
substance. Scape leafy below, pulverulent, bearing an erect
raceme of handsome scarlet flowers. Pedicels bracteated, ‘stand-
ing out almost horizontally and, as well as the calyx, pulverulent.
Calye of three, imbricated, erect sepals, about three-quarters of
an inch long, red with a yellowish margin. Corolla scarlet,
nearly three inches long, curved. Petals \inear-oblong, not at
all spreading, slightly spirally twisted: near the base within is a
conspicuous, membranous, two-lobed scale, the lobes slightly
serrated. Stamens as long as the petals. Ovary glabrous,

oblong-ovate: style rather longer than the stamens: stigmas
three, ciliated. W. J. H.
Cutt. Tropical America and the West Indian islands are the
native places of the genus Pitcairnia. They generally inhabit
dry places, where there is little or no soil. They increase by
suckers, and ultimately become dense ceespitose tufts, sometimes
found growing on trees. They appear able to bear a great:
degree of heat and drought, but in a state of cultivation they
improve in appearance by allowing thema due share of moisture.
‘This pretty species has flowered in the Orchid-house, under the
influence of a moist and warm atmosphere, in which it appears
to thrive. A soil composed of light loam and peat suits it. It
is increased by taking off the young suckers, which root freely
without the aid of a bell-glass. /. 8,

Native of India ;—according to Dr. Lindley, of Nepal, Ben-
gal, Ceylon, and probably Java.” It blossomed in 1842 with
Messrs. Rollisons, at Tooting, but, though a handsome and
really striking plant, it had never been figured. Our fine
tuft of the plant at Kew, which blossomed in July and August,
was derived from Mr. Clowes’ collections.

late, tapering below, acuminated at the apex, plaited and striated.

Cur. This, being an East Indian terrestrial Orchid, requires
to be grown in a moist tropical stove. It thrives in turfy peat
containing a small portion of loam. On account of its soft fleshy
roots adhering to the sides of the pot, it is desirable to use a
shallow wide-mouthed pot, in order to avoid tearing the roots by
frequent shiftings. In summer it may be freely watered, but
the pot must be well drained, so as to allow the water to pass
off freely. Shading is necessary during bright sunshine. In
winter it should be placed in a drier atmosphere, and especial
care must be taken that no water be allowed to lodge in the
folds of the young leaves. J. 8. |

nune prolifero, petalis obovato-lanceolatis sulphureis roseo tinctis.
Opuntia Satmrana, Parment. in Pfeiff. Enum. p.112. Salm-Dyk, Cactea, p.70.
This pretty and very distinct Opuntia is said to be a native of
Brazil. Our collection is indebted for the possession of it to the
Royal Gardens of Herenhaussen. It blossoms freely, and the
ordinary-looking stems and branches are ornamented by the
variegated red and yellow and rather copious flowers in Sep-
tember and October. In the generic character we follow
that given by the venerable Prince de Salm-Dyk in his recently-
published volume entitled Cactez,”” a work which ought to be
in the hands of every cultivator of this curious tribe of plants.
Drscr. Plant small, one to two feet high, erect, branched,
branches erecto-patent, cylindrical, rather of an ashy-green colour,
destitute of tubercles, obtuse at the apex. Areoles scattered,
forming white downy tufts of wool, bearing six to eight unequal,
brown, small aculez, the largest less than half an inch long.
Flowers moderately sized, clustered at the apex of a branch.
Ovary obovate, not scaly but areolated, and bearing aculet
like the branches, and, what is remarkable, after the floral

coverings have fallen away, often producing young plants, —proli-
ferous. Sepals and petals undistinguishable, or, in other words,
the former gradually pass into the latter. In bud the flower is
red, when fully expanded the ground-colour is sulphur-yellow,
streaked with red and rose-colour in the centre: the petals are
obovate, and the spread of the flower about two inches. Stamens
not numerous, yellow. Rays of the stigma five or six, yellow-
green. W. J. H.
Cur. This slender straggling species grows and flowers freely
if potted in light loam and leaf-mould, and placed under the
full influence of the sun in summer. It should be frequently
syringed in the mornings or evenings, during hot dry weather,
but care must be taken that all superabundant water passes off
freely, and that the soil does not remain long in a saturated
state. In winter water must be given very sparingly, and the
temperature of the house during the night need not at any
time exceed 55°. It readily increases either by cuttings or by
seeds, as also by gemme produced on each areole of the fruit,
which ultimately form separate and distinct plants. /. 8.

One of the many good Swan River plants raised by Messrs.
Lucombe, Pince, and Co., Exeter Nursery, from seeds received
from Mr. Drummond. It is new to Dr. Meisner, as he recently
informed us, and has no place in the ‘ Plante Preissiane. Per-
haps its nearest affinity is with P. fincloria, Meisn., though the
leaves do not change to the very peculiar green described as
characteristic of that species, and it wants several other distin-
guishing marks. It bears the number 426 in Mr. Drummond's
Swan River specimens in my Herbarium. It is a highly in-
teresting addition to our greenhouse plants, easy of culture, and
free to blossom in the summer months. :

latter is two inches and a half across. //owers numerous, dense,

tube of the calyx) turbinate, quite truncated at the top, hairy.
Tube of the Perianth slender, long, downy, articulated on the
truncated summit of the ovary; the segments of the limb ob-
long, spreading or recurved, ciliated at the margins. Stamens

Curr. An Australian genus, consisting of slender twiggy
shrubs, and now numbering above fifty described species.
The greater number are natives of Van Diemen’s Land and the
extra-tropical coasts of Australia, many being found at Swan
River and at King George’s Sound on the south-west coast : a few
extend northward to within the tropics, and several are natives
of New Zealand. About twenty species are known to have been
introduced into the gardens of this country. ‘The first was
P. linifolia in 1793, followed by P. rosea in 1800; between the
latter year and 1823, P. drupacea and P. pauciflora were intro-
duced: the first two, being pretty flowering species, were fre-
quent inmates in the greenhouse, whereas the two latter,
having inconspicuous flowers, were seldom seen, except in collec-
tions where rarity and number of species were desired. In
1823 we were so fortunate as to raise plants of P. decussata,
which, on account of its being of neat habit anda free and
showy flowering species, soon became a favourite with culti-
vators, but has of late been in some measure superseded by
its more showy rival, P. spectabilis, which was introduced about
ten years ago. The species now figured is of recent introduc-
tion, and, from what we know of it, will turn out to be another
showy species. It is, like its allies, a greenhouse plant, and
grows vigorously if planted in turfy peat-soil, containing a little
Joam, and kept sufficiently drained. Over-watering is unde-
sirable, especially during dull damp weather in winter and
spring ; and in hot weather the sides of the pot must not
be exposed to the direct rays of the sun. It will propagate by
cuttings, placed under a bell-glass, and treated in the usual
way, but it has been found to produce the best plants if grafted
on stocks of P. decussata. J. 8.

This is really a noble plant or tree, thirty feet in height, as
now seen in the great stove of the Royal Gardens of Kew, with
a large rounded head of copious branches, and dense foliage,
studded, in the spring months, with numerous snowball-like
capitula of flowers, each flower stained with a deep blood-
coloured eye. M. Guillemin, |. c., has very correctly given the
history of its introduction. “ Cette belle plante, he says,

standing it has been thus liberally distributed from England

la beauté de cette fleur (at the garden of Neuilly), ayant chargé
M. Redouté d’en faire la peinture, cet artiste celébre a bien
voulu communiquer & M. Guillemin un échantillon de la plante,”’
&c. Our own knowledge of this amiable personage suffices to
assure us that such a change would be considered no compliment
to herself. The flowers have a honey-like smell.
Descr. Arborescent, with a dense crown of branches and
copious foliage. The young herbaceous éranches and nascent
leaves, accompanied by large, cordate, afterwards deciduous
stipules, are exceedingly viscid. Leaves on long petioles, the
largest of them a span and more Jong, cordato-rotundate,
five-angled (the smaller ones three-angled), the angles or lobes
acuminate, the margins serrated. From the axils of the leaves
towards the extremity of the branches, the peduncles appear, a
span long, bearig two cordate dracteas above the middle. ‘The
flowers of the young capitulum are clothed by the large deci-
duous bracteas (one to each flower), and at the base of the capi-
tulum three or four such bracteas form an imperfect involucre.
These bracteas disappear on the full expansion of the many
flowers into a globose head, four inches and more in diameter.
Pedicels hairy. Calyzx-segments ovate, acuminate, hairy exter-
nally. Petals five, twisted, broad-cuneate, pure white, the base

Cuxr. This is a tropical, soft-wooded, branching tree, of quick
and robust growth, soon arriving at a height that renders it
unsuitable for hothouses of the ordinary dimensions. In
the Royal Gardens it has rapidly attained the height of up-
wards of twenty feet; but, as it branches freely, it may, with
management, be kept within bounds by frequently cutting back
the leading shoots. It grows readily in light loam, and should
be rather freely supplied with water, as its numerous fibrous
roots take it up very quickly, and the size and texture of its
leaves present a large and free evaporating surface. It is easily
increased by cuttings, planted under a bell-glass, the pot being
plunged in bottom heat. 7. &. |

A very remarkable stove-plant, native of copses in the moun-
tainous districts of Java, detected by Blume, and imported into
England by Messrs. Veitch and Sons (to whom we are indebted for
living plants) through the medium of their collector, Mr. Thomas
Lobb. We agree with Dr. Lindley that, remarkable as 1s the
form of the corolla, there is nothing to justify its separation from
Hoya; and it does not accord with Physostelma of Dr. Wight,
to which Professor Decaisne has doubtfully referred it. If dis-
tinct from Hoya, it should bear Harskal’s name above quoted.
Blume makes a section of it: “ Corolla campanulata, angulato-
5-plicata, corone foliolis angulo exteriori adscendentibus integer-
rimis”? It bears its curious, somewhat waxy and pale buff-
coloured flowers in August.
Descr. A long-stemmed twining shrub, with slender branches.
Leaves opposite, oval-oblong, acuminate, scarcely coriaceous,
penninerved. Petiole nearly half an inch long. Pedunele slen-—
der, drooping, as is the large capitate umbel. Pedicels very
slender. Calyx small, of five lanceolate sepals. Corolla large,
an inch and a quarter to an inch and a half in diameter, between
membranaceous and fleshy, somewhat waxy, buff-coloured,
broadly and shallow-campanulate, plicate, the margin cut into

Curr. A climbing plant, which, as regards its habit, may
be considered a thin-leaved Hoya. Being a native of Java,
it requires to be kept in a warm and moist stove. A mixture
of light loam and peat will suit it, and during its season of rest
care must be taken that it is not saturated with water. Its
pendulous umbels of flowers are shown most to advantage by
training the plant up a rafter, or something similar, in a nearly
horizontal direction. It is easily propagated by cuttings. J. S.

A Jamaica shrub or small éree, inhabiting the higher moun-

both in the leaves and flowers, to the black Tea of China, Thea
Bohea; and Dr. M‘Fadyen informs us, in his useful ‘ Flora
of Jamaica,’ that the leaves are astringent, and in taste resemble
those of the green Tea. Although described by Swartz, no
figure has yet appeared of it; nor are we aware it had yee
introduced ‘alive to Europe, till recently sent by our friend Mr.
N. Wilson, of the Botanic Garden, Jamaica, to the Royal Garden
of Kew. From these flowering plants our drawing was .
in September 1850. oe :

merous, attached to the base of the petals. Axthers oblong,
opening by two pores, apiculate or furnished with a tuft or
pencil of hairs at the back. Ovary subglobose, glabrous, tapering
into a short séyle, trifid at the point. Fruit “a berry, the size
of a small cherry, globose, purple, juicy, three- or four-celled.
Seeds many, angulated.” W, J. H.
Curr. Although not a showy flowering plant, its neat
and evergreen habit renders it worthy of a place in general
collections of stove-plants. It much resembles the well-known
Ardisia crenulata, but grows more luxuriantly ; as, however, it
bears cutting back, it may be kept to a proper size, and will
form a neat bush. Being a native of Jamaica, it should be
grown in a moderate stove temperature, and will thrive in any —
kind of light loam, water being freely given it during dry wea- —
ther in summer. It is readily propagated by cuttings, planted
: = ses a bell-glass, and plunged in a moderate bottom-
eat. J. WS.

either grown in a pot, and supported by neat rods or a wire
trellis fixed to the pot; or planted out in a border against a
back wall or pillar. A mixture of light loam and peat will suit
it. The usual precautions must be taken that the soil does not
become stagnant by over-watering,—a rule to be carefully ob-
served with plants generally, especially those with fine fibrous
roots, when cultivated m large pots. Great mischief results
from injudicious watering ;—not so much from giving too great
a quantity of water when a plant really needs it, as from the
common practice of watering often, and giving a little each time.
The consequence is, that either the lower roots receive no water,
or the soil becomes a stagnant wet mass, which, even if no more
water is given, will take a long time to come to the proper
degree of dryness; in the meantime the roots suffer, as is
shown, when too late, by the unhealthy appearance ‘of the
plant. J. 8.

This handsome plant, with flowers of the size and colour of
Lemonia spectabilis, but arranged in a compound raceme or
thyrsus, is one of six species of a shrubby new genus, detected
in Brazil by M. Auguste de St. Hilaire. He dedicated it to his
friend and patron Don Rodriguez Pereira de Almeida, and re-
ferred it to the “ Rutacées proprement dites”’ (Tribe Diosmee,DC.);
but remarks that it is of all others of that group the most allied
to Cuspariee. “It possesses the calyx and nectary of Cuspa-
rie@ ; its stamens are those of Galipea ; its ovules, two in num-
ber, are attached as in Cuspariee ; its false arillus is the same —
as in Monniera ; and, in fine, its embryo, destitute of perisperm,
with the radicle curved and the corrugated cotyledons, the one
enveloping the other, resembles that of Galipea Fontainesiana.”
Our plant was received from Mr. Makoy of Liége, and its
flowering-season with us is the autumn. a

minate at the apex, penninerved, quite entire at the margins.
Petioles an inch long or more. Panicle, or compound raceme,
thyrsoid. Pedicels glabrous, thickened upwards, with small
deciduous Jracteas. Flowers often two or three together, mode-
rately numerous. Calyx short, cut into five acute teeth. Petals
obovato-spathulate, very obtuse, spreading, deep rose-colour (as
is the calyx). Filaments of the stamens linear, contracted below
the anther, slightly downy, grooved towards the base, and above
the groove are two hairy tubercles. _Anthers oblong. Ovary of
five lobes, pellucido-punctate, surrounded by an entire, cup-
shaped nectary. Style longer than the stamens. Stigma capi-
tate, obscurely five-lobed, W. J. ZH. :
Curr. The genus to which this plant belongs is from tro-
pical America, chiefly Brazil ; its species therefore require to be
grown in a stove temperature. The one here figured flowered
during the month of September in the Palm-house. It should
be potted in a mixture of light loam and Jeaf-mould, and receive
the benefit of bottom-heat, which we consider of great impor-
tance in cultivating, and maintaining in a healthy state, plants
of slow growth like the present. It is increased by cuttings
plunged in bottom-heat. 7. 8.

M. Auguste St. Hilaire, under the genus Pachira, justly ob-
serves, “Le diagnostic des espéces de ce genre est fort difficile
& établir ; car ses fleurs, qui généralement ne se développent pas
en méme temps qui les feuilles, ont été souvent seules observees
et recucillies par les voyageurs ; et, uniformes dans leur structure,
elles ne présentent pas entre elles des differences assez saillantes
pour qu’on puisse les caractériser en peu de mots.” These ob-
servations will apply eminently to the P. (Carolinea) macrocarpa
of Chamisso and Schlechtendal, in the Linnea above quoted ;
and, indeed, the authors candidly remark of their plant, “ Flores
ex alabastro nobis imperfecte noti.” Nor should we venture to
call this plant “ macrocarpa,” but that it was received from
Mr. Makoy under that name, who probably derived it from
Berlin, where the seeds of the original macrocarpa were raised.
It is a native of Mexico. ‘The flowers are truly magnificent, and
yet produced in the present instance from a young and small
plant. As a species it comes very near the P. aquatica of
Aublet, and may probably prove identical with it.
Desor. Of the ordinary size of the native plant we are ignorant.
Our flowering specimen had not attained a greater height than
four feet, and what gives this a decided advantage over our

eleven /eaflets, which are oblong-obovate, entire, acuminate,
cuneate, and tapermg at the base into a short footstalt. Flowers
very large. Calyx short-cylindrical, truncated; thick and lea-
thery, clothed with minute, velvety down, bearing a circle of
conspicuous glands at the base. Peéals full six inches long,
hnear-strap-shaped, the upper half reflexed, white and smooth
within, pale greyish or greenish-brown and slightly velvety
externally. Staminal tube rather short, divided into innumerable
parcels, each again divided“into eight to ten fi/aments, which are
yellow below, the rest deep red. _Anthers narrow linear, arcuate.
Style longer than the stamens, deep red, slender. Stigma small,
five-lobed. W. J. H.
Cuur. This, like Pachira alba, figured at Tab. 4508, is a tall
tree of rapid growth, and, as it requires the temperature of a
stove, it is adapted only for growing in lofty hothouses, such as
the Palm-house in the Royal Gardens, in which a plant has
quickly attained the height of twenty-five feet, and, according to
_ its present rate of growth, will soon double that height. It has
not yet flowered, the present figure having been drawn from a
plant that bloomed when not more than a foot in height, and
which had but recently been struck from a cutting. It is a fine-
looking tree, not subject to insects of any kind, and differs from
Pachira alba in its leaves not being deciduous : in our cultiva-
tion it appears to have no season of rest. It will grow freely in
any kind of light loam, kept in a proper state of moisture, and
increases by cuttings placed under a bell-glass, and the pot
plunged in bottom-heat. J. S.

Raised at the Royal Gardens of Kew, from seeds sent by Dr.
Hooker, which were gathered in June 1849, from plants growing
on gravelly banks at Lachen, Sikkim-Himalaya, one of the Passes
into Thibet ; elevation, 10,000 feet above the level of the sea. It
is, although of the same groupe of Primule with the P. denticu-
lata of the Nepal mountains and our own P. farinosa of the
north of England and Scotland, a remarkable and well-defined
species, the flowers being actually sessile, and so crowded as to
form a compact globose head, like that of many species of A/-
lium. or Armeria. Dr. Hooker observed that it yields a faint
fragrance, which it does in cultivation, but this, in part at least,
is derived from the farinaceous substance of the leaves and
flowers. It flowers with us in a pot in the rock-border, in-
October. :

red at the base. Scape often a foot long, moderately stout and
thickened upwards, mealy, terminated by a dense globose head
of flowers, bracteated at the base, the outer dracteas lanceolate,
and forming a small, reflexed cnvolucre. Calyx sessile, mealy,
large, campanulate, deeply 5-fid, the segments ovate, acumi-
nate, subpatent. Corolla with the tube nearly twice as long as
the calyx, almost white, mealy, a little inflated upwards, and
transversely wrinkled ; Zimé of five, obcordate, spreading /odes,
deep purple above, pale beneath. _Anthers small, nearly sessile,
inserted below the middle of the tube. Ovary globose. Style
filiform, as long as the tube. Stigma large, capitate. W. J. H.
Cur. In habit this approaches our native species, P. farinosa
and P. Scotica, and although it is a native of a high region and
consequently subjected to a great degree of cold, yet, like other
alpine species of the genus, it will probably require some slight
protection in this climate, especially under our artificial mode of
cultivation. During the past summer we had a number of
plants growing very luxuriantly,—apparently too much so, for
not one of them has yet shown any appearance of flowering.
The present figure was drawn from a plant that had not been so
well taken care of, and was stunted in its growth. Several of
the vigorous plants suddenly died: it is therefore safest, till
we become better acquainted with this species, to grow it in a
frame during winter; and in summer to set it in a shady place,
that it may escape the heat of the sun in the middle of the day.
It appears to suffer by frequent watering overhead, the pot
should, therefore, be placed in a pan, so as to receive water from
the bottom. 7. 5

This is one of the many lovely tropical plants now cultivated
in our stoves, distinguished by the “ folia discolora ;” that is, the
upper and underside differmg in colour, and the upper with a
rich and glossy surface, refracting the rays of light m such a
manner as to give a coppery or velvety hue, not easily repre-
sented in a drawing. he subject of our present plate was
received at the Kew Gardens from Mr. Henderson, St. John’s
Wood Road Nursery, under the name of Hriocnema eneum ot
Naudin. But the plant is no Hriocnema. It belongs to the
curious and beautiful genus Bertolonia, “ dont le caractere essen-
tiel consiste,” as M. Naudin has himself well expressed, dans
la forme tout-d-fait insolite du calyce et de la capsule ;” and it
is equally certain that it is the B. maculata of De Candolle and
of Martius above quoted, t. 257. his fruit or capsule is an
elegant object, especially when the eye is aided by a small power
of the microscope ; for it is singularly inflated, with three very
prominent angles and several ribs, and every rib, as well as the
margin of the lobes of the calyx, is beset with bristles, termi- 2

nated by a gland. In many, and perhaps all the Bertolonias, a
singular appearance is given to the specimens by the persistent
dead and perfectly bleached thickened flower-stalks and fruits
upon the otherwise healthy plant. In our representation of the
plant the term “maculata” may be deemed incorrect; but
exactly in this state Martius represents. his native specimen,
and he observes of the leaves, “supra saturate viridia et saepe
more Pulmonarie officinalis maculata.” Our wild specimens
from Mr. Gardner (Herb. Braz. n. 1009) have a pale cloud or
blotch extending to both sides of the costa; and we have a
variety or allied species from St. Sebastian (gathered by the late
Mr. Fox and given to us by Mr. Bunbury), with quite distinct
oblique red spots between the nerves in regular series the whole
length of the leaf. Martius found our present species in the
province of Bahia, Mr. Gardner in that of Pernambuco.

many months under our notice, but appears to grow and flower
freely, in a small pot, in light peat-soil. As it has very fine
fibrous roots, care must be taken that it be never allowed to
remain too long dry. Judging by its habit of growth, it is not
likely that much increase of it can be obtained by cuttings, but,
to all appearance, it will produce perfect seeds. /. S.

CENTROSOLENIA glabra. Benth. MSS.
An interesting and rather handsome Gesneriaceous plant,
imported by the Royal Gardens of Kew from La Guayra,
through Mr. Wagener, a German collector, who has been long
travelling in that country. It forms a stove-plant, and keeps up
a succession of flowers with us through the autumnal and early
winter months. We submitted the figure to Mr. Bentham for
his opinion, as he has paid much attention to the family to
which it belongs, and has published the results of his observa-
tions in the 5th volume of the ‘London Journal of Botany,’
p. 357, &e. ‘That gentleman considers the plant as clearly con-
stituting a second species of his new genus Centrosolenia (I. c.
p. 362), and he has obligingly furnished the accompanying
character and description. M. Decaisne’s genus 7richanthe,
since published, probably in the ‘Revue Horticole,’ for 1548,
he believes to be identical with Centrosolenia. If so, it must
give place to the latter name, which appeared in 1846, and con-
sequently has the right of priority.
Dxescr. An erect plant, with a succulent, reddish-brown,
terete stem, a foot or more high. eaves succulent, glabrous,

minate ; the other large, ovate, tapering at the base into a stout
petiole, and acuminate at the apex, the margin serrated. Pedi-
cels aggregated, axillary, downy, six to seven lines long, hairy.
Calyx entirely free, the four lower lobes lanceolate-linear; about —
nine lines long, with one or two shorter or longer teeth above
the middle, coloured and slightly hairy ; the upper lobed, much
shorter, and narrow, deflected by the spur. Corolla tubular,
enlarged upwards, projected below into a short obtuse spur, the
whole tube about an inch and a half long, clothed outside with
a short thin down, the Zimé divided into five broad short lobes,
of which the three lower are fringed with long thread-like
laciniz ; inside of the corolla smooth. Stamens inserted near
the base of the corolla: filaments smooth, anthers cohering,
slightly fringed with hairs at the lower end. .Rudiment of the
fifth stamen small. Annular disc nearly obsolete, with a large
posterior gland. Ovary conical, hairy, with two lamelliform,
bipartite, parietal placenta. Style smooth, thick, somewhat
clavate, with the stigmatic extremity rarely emarginate. Benth.
Cuur. A tropical soft-wooded plant, of robust, straggling
growth, and, like many other Gesneriaceous plants, of an epi-
phytal habit, and will grow freely on decaying vegetable matter
imawarm and moist atmosphere. The plant here represented
was raised from seed, and has grown luxuriantly in a mixture
of light loam and peat-soil. It is readily increased by cuttings,
which produce roots without the aid of a bell-glass. J. 8.

Though not so strikingly beautiful as the O. ora paniculata, ;
figured by Dr. Wallich in his superb ‘ Planta Asiaticee Rariores,’
yet this is very nearly akin to it; and but for the well-known ac
curacy of my valued friend just mentioned, and the fact of his havi
seen both species in a living state, I should have been dispc
to have considered the present a lax-branched and lax-flower
variety of O. paniculata :—the more so, as he quotes from
-Roxburgh’s MSS. a still more lax and drooping variety
O. paniculata is indeed a stouter and stronger plant, wit.
stem and panicle erect, and “connectivo antherarum
obsolete calcarato ;” whilst in our plant, which quite
with the Wallichian specimen in my herbarium, the connectivum
