289. ROYDSIA SUAVEOLENS. 
OBSERVATIONS. 
Maudobe-lata the vernacular name in Sz/het, where the plant is 
indigenous. Flowering time the month of March, when its 
numerous blossoms diffuse a strong, but pleasant odour through 
the forests where they grow. Seed ripen in August and Sep- 
tember. 
DESCRIPTION. 
Stem stout, woody, and with its numerous branches climbing over 
trees to a great extent. Bark of the young shoots green, 
void of pubescence, but covered with numerous, small, 
elevated, whitish specks. ; 
Leaves alternate, short-petioled, oblong, entire, of a firm texture, 
and smooth on both sides, sometimes pointed: length about 
six inches, and about two and-a-half and three broad. 
Stipules none. 
Inflorescence terminal and axillary ; when terminal it is generally 
a long, slender panicle, as long as the leaves; when axillary 
a simple raceme. 
Flowers numerous, alternate, short-pedicelled, pretty large, pale 
yellow, and fragrant. 
Bractes solitary, oblong, villous, one-flowered. 
Calyx inferior, one-leaved, 6-cleft, villous; segments ovate in a 
double series ; exterior three rather larger. 
Corol none, nor any thing like a nectarial organ. 
Filaments numerous (about one hundred), length of the pistillum 
and its pedicel, inserted on the apex of a short column. 
Anthers incumbent. 
Germ pedicelled above the elevated receptacle of the stamina; 
oblong, 3-celled, with about two rows of ovules in each, 
attached to the axis. Style very short. Stigma trifid. 
Drupe pedicelled, size of a large olive, oval, covered with a rather 
scabrous, orange-coloured, thin, brittle cortex, one-celled. 
Pulp in considerable quantity, soft and yellow. Nut oblong, 
texture of a soft ligneous mature and thin, one-celled, 
3-valved. 
Seed solitary, conform to the nut: Integument single, membra- 
naceous. ' 
Albumen none. : 
Embryo erect. Cotyledons two, unequal ; the larger deeply con- 
cave, receiving the smaller doubled one into its concavity as 
in the Shoree ; they are of a firm fleshy texture, and yellowish. 
Radicle inferior, and rather within the base of the cotyledons. 
290. UNONA LONGIFLORA. 
Leaves linear-oblong. - Flowers 2-3 petalled, of great length, and 
pendulous oints of the Berries few and linear-oblong. 
* This elegant, clearly-marked genus is named in honour of Sir Joun Royps, one of 
the puisne Judges of the Supreme Court of Judicature of Bengal; a zealous Botanist 
and an eminent benefactor to the science. 
UNONA LONGIFLORA. 88 
OBSERVATIONS. 
Collahcurrah, the vernacular name in Silhet, where it is indi- 
genous ; grows to the size of a large shrub, or small bushy tree. 
Flowers in April and May, and the seed ripen about the close of | 
the rains. 
DESCRIPTION. 
Young shoots quite smooth, round, and flexuose. 
Leaves alternate, bifarious, short-petioled, linear-oblong, entire, 
smooth on both sides, and particularly glaucous underneath ; 
from six to twelve inches long, by 2-4 broad. 
Peduncles axillary, solitary, from three to ten inches long, filiform, 
smooth, one-flowered. 
Flowers uncommonly long, pendulous ; outside bright orange, 
inside yellow. 
Calyx 3-leaved: leaflets reniform-cordate, acuminate, very small, 
and hairy. 
Petals two, rarely three, ensiform, thick, and fleshy, 6-8 inches 
long, both sides smooth; inside yellow, outside orange. 
Stamina numerous, glandular-headed, forming, a hemispheric ball 
round the germs. 
Germs 10-20, sessile, clavate, very hairy, one-celled, ovules a few, 
imbricated upward, and vertically attached to the inner 
margin of the cell. Styles short. 
Berries several, long-pedicelled, drooping, 2-4-jointed: joints 
linear-oblong, or sub-cylindric, smooth. 
Seeds one in each joint, and of the same form, smooth. Integument 
polished, of the consistence of parchment, 2-valved, from 
its inside innumerable fibres project into the albumen. 
Embryo in the base of the albumen, &c. kc. exactly as in the 
Uvaria ; see Gert. sem. 2.155. #. 114. 
Stigma large, recurved. 
291. INCARVILLEA PARASITICA. 
Shrubby, parasitic, smooth. Leaves opposite, lanceolar, vein- 
less, fleshy. Umbels terminal. 
OBSERVATIONS. 
A native of the forests which cover the Garrow hills, where it 
is found growing on trees ; but shows a partiality for such places 
as retain decayed vegetable matter. In the Botanic Garden at 
Calcutta it grows freely in a soil composed of rotten wood, and 
garden mould. Flowering time the rainy season, when nothing 
can exceed the beauty of its numerous, large, pendulous, crimson- 
yellow flowers, approaching in shape and size to those of Digitalis 
purpurea. Seed ripen in September and October. 
DESCRIPTION. 
Stem scarce any, but several, rather succulent, smooth branches, 
with swelled joints ; from those the fibrous roots issue. 
Leaves opposite, or nearly so, short, fleshy-petioled, lanceolar, 
acuminate ; margins more or less curled; substance firm, 
fleshy, and veinless ; length 4-6 inches, by one broad. 
Umbels terminal, solitary, sessile, simple, many-flowered. 
Flowers large, drooping, colour a beautiful mixture of orange and 
crimson. 
Bractes : an oblong caducous one at the base of each pedicel.
