be kept dry ; early in spring, they must be 
examined, repotted if necessary, placed in 
heat and watered sparingly ; light loam and 
peat soil ; propagated by offsets. 
Roupellia grata, Wallich and Hooher 
(Cream-fruit). — Apocynaceas § Plumiereas. — 
A very handsome and very fragrant plant, 
called the '' cream-fruit " by Afzelius, probably 
from the use occasionally made of the cream- 
like juice of the fruit. It is a smooth climbing 
shrubby plant, of free growth, with the habit 
of the African Tabernamontanas. The leaves 
are opposite, large, leathery, oblong elliptic, 
shortly acuminate, and attached by a short 
petiole. The flowers grow in terminal sessile 
cymes of from six to eight flowers, arranged 
in a somewhat umbellate manner ; they are 
large, full three inches across, with a funnel- 
shaped tube, and a broad limb of five obovate 
unequal wavy segments ; the colour is white 
with a tint of rose, the coronet, which forms 
a ring of erect linear- lanceolate filaments, 
being of a pretty rose-colour. Native of Sierra 
Leone. Introduced about 1847. Flowers in 
May. The plant is the Strophanthus Stan- 
leyanus of gardens. Culture.' — Requires a 
hot moist stove ; loam and peat in equal pro- 
portions ; propagated by cuttings, planted in 
sand under a bell-gla-s and placed in heat. 
Aristolochia macradenia, Hooker (large- 
glanduled Birthwort). — Aristolochiaceaa. — A 
curious smooth sufFruticose climbing plant, 
with long slender stems, bearing alternate 
leaves, which are four or five inches long, 
and in form between heart-shaped and halberd- 
shaped. The flowers grow singly from the 
axils of the leaves ; they are about three and 
a-half inches long, and of the singular form 
which prevails among the birthworts ; they 
are monopetalous, with a tube about an inch 
and a half long, the lower half of which is 
much swollen, the upper half contracted, all 
of a greenish colour ; above this it opens into 
a dilated, declined, ovate lip, the sides of 
which are revolute ; the upper surface of this 
lip is rich brown with yellow reticulated veins, 
and it is beset with large stalked globose 
glands, which give it a peculiar appearance. 
Native of Mexico, about Real del Monte. 
Introduced in 1847. Flowers in the spring. 
Culture. — Requires a warm greenhouse ; light 
loam and peat ; propagated by cuttings, placed 
in a gentle heat. From its moderate sized 
growth, it is suited for growing it a pot. 
Cyrtanthera aurantiaca, Hooker 
(orange-flowered Cyrtanthera). — Acanthaceas. 
— Ahandsome soft-wooded shrubby plant, with 
erect acutely four-sided stems and branches, 
bearing opposite broadly elliptical lanceolate 
rather rigid leaves, and terminated by large 
dense bracteated ovate thyrses of large hand- 
some bright coloured flowers. The flowers 
are labiate, the tube about as long as the limb, 
the upper lip of which is erect with a bifid 
point, the lower lip oblong, refiexed, and 
three-cleft; the colour is a full golden yellow 
at the first expansion, the tube and lower 
lip afterwards becoming orange-red. Native 
probably of South America. Introduced to 
England from Belgium, by Messrs. Henderson 
of Pine-apple Place, in 1848. Flowers ? 
It is the Calcostylis aurantiaca of Makoy's 
catalogue. Culture. — Requires a stove ; light 
loam and leaf-mould ; propagated by cuttings 
placed in a gentle heat. 
Rhododendron formostjm, Wallich (beau- 
tiful Rhododendron). — Ex-icaceas § Rhododen- 
dre?e. — One of the slender growing and 
elegant species of the extensive family of 
Rhododendron. It is a truly beautiful and 
rare species, forming a small slender shrub, 
with reddish brown branches, oblong-obovate 
obtuse leaves, tapering into a short foot-stalk, 
and flowers in pairs produced from the tops 
of the branches, but soon over-topped by 
young shoots and appearing lateral ; the blos- 
soms are large, well formed, delicate white, 
tinged with yellow and rose, and having five 
external stripes of red. Native of the Hima- 
layan mountains of India. Introduced in 
1837. Flowers in spring. It is the Rhodo- 
dendron Gibsoni (Paxton), under which name 
it is known to cultivators, but it was pre- 
viously known to science under Dr. Wallich's 
name. When cultivated to the perfection to 
which Indian azaleas are now brought, this 
will be a highly ornamental shrub. Culture. 
— Requires a greenhouse, and the ordinary 
management of greenhouse azaleas ; light peat 
soil ; propagated by seeds, which, being very 
small, should be scattered on the surface of 
peat earth kept moist ; or by inarching on 
more common and free-growing kinds. 
Platycodon autdmnale, Decaisne (au- 
tumnal Platycodon). — Campanulaceas § Light- 
footeae. — A plant described as being some- 
thing in the way of Platycodon grandijiorum, 
the old Campanula grandiflora. This is said 
to be of compact habit of growth. The leaves 
are not described. The flowers are blue, the 
corolla being velvety at the bottom of the 
tube ; the technical distinction of this species 
consists in the following character : — " Fila- 
ments dilated at the base, partially ciliated, 
bluish, marked with a demi-circular depres- 
sion at the base of the linear portion which 
bears the anther, which is linear, pointed, and 
two lobed." Native country not stated. In- 
troduced to the garden of the Museum at 
Paris, before 1848. Flowers in autumn. 
Culture. — Hardy in the climate of Paris ; 
dryish loamy soil ; propagated readily by 
division of the root, or by seeds.
