Follicles 6 by 4 in. quite straight, horizontal, cylindric, acuminate. Seeds linear, 
1 in., softly villous, coma copious, four times longer.— The fruit figured and described 
by Roxburgh, A. DC., and Wight as that of U. elastica is Orchipeda fetida, Blume, a 
plant cultivated in India. Wallichs U. elastica (Cat. 1617), from Penang, is an

ollicles cylindric.

Habit and brown colour of U. elastica, but the leaves are quite glabrous and 
apparently glaucous beneath, with fewer more arched nerves not impressed above. The 
cymes are smaller, fewer and laxer-flowered; the calyx-segments much broader and 
very obtuse ; the anthers and style are the same in both, but the follicles are much 
more slender in A. Maingayi. 
3. U. lucida, Benth. in Gen. Pl. ii. 716 ; quite glabrous except the inflo- 
rescence, leaves elliptic abruptly acuminate shining on both surfaces, nerves 
8-12 pairs, cymes lax-fld. finely pubescent, bracts subulate, calyx-segments 
broadly oblong, follicles short gradually acuminate from a broad base. Cha-

Branches slender; bark nearly black, smooth. Leaves 3-5 in., rigidly coriaceous, 
red-brown when dry; nerves arched, strong beneath; petiole slender, 1-1 in. Cymes 
long-peduneled ; peduncle and branches very slender; bracts subulate; flowers very

hairy at the tip only; style elongate with an obconoid top surmounted by

plant is in very young flower and may be another species; it has larger leaves with 
fewer and very slender nerves. The Rangoon specimens have caudate-acuminate 
leaves, larger bracts and hispidulous flowers. Kurz (in Journ. As. Soc. 1877, ii. 255) 
refers this to U. esculenta, 
4. U. malaccensis, Hook. f.; quite glabrous except the inflorescence,

surfaces ` nerves arched, nervules obscure; petiole }-} in. Cymes chiefly axillary ; 
peduncle glabrous, shorter or longer than the leaves; bracts 4—4 in., recurved, much 
larger than in the foregoing species; flowers hoary rather than pubescent. Corolla 
as in the preceding species. Anthers obtuse. Ovaries hirsute; style obconie, sur- 
mounted with an obpyriform stigma. Follicles described by Maingay as “ elongate 
filiform divarieate. Seeds oval, compressed, pilose at the apex.”
