the stamens. Anthers acuminate. Style obconoid, with a small conoid stigma.. 

 Follicles 6 by in., quite straight, horizontal, cylindric, acuminate. Seeds linear, 

 in., softly villous, coma copious, four times longer. The fruit figured and described 

 by Koxburgh, A. DC., and Wight as that of U. elastica is OrcMpeda fcetida, Blume, a 

 plant cultivated in India. Wallich's U. elastica (Cat. 1617), from Penang, is an. 

 Asclepiadeous plant without flower or fruit. 



2. IT. IVIaing-ayi, Hook. /. ; quite glabrous except the inflorescence, 

 leaves elliptic abruptly acuminate thickly coriaceous, pale beneath, nerves 6-1 (> 

 pairs strong, cymes finely pubescent, calyx-segments oblong obtuse recurved, 

 follicles cylindric. 



SINGAPORE, Maingay (Kew Distrib. 1083). 



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 

 eery obtuse ; the anthers and style are the same in both, but the follicles are much 

 more slender in A, Maingayi. 



3. U. lucida^ jSewtfA. 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-

, PENANG; Wallich. ? MALACCA; Griffith. EANGOON; McLelland. 



Branches slender ; bark nearly black, smooth. Leaves 3-5 in., rigidly coriaceous, 

 red-brown when dry; nerves arched, strong beneath; petiole slender, ^-1 in. Cymes 

 long-peduncled ; peduncle and branches very slender ; bracts subulate ; flowers very 

 minute, ^ in. long. Corolla as in the preceding species. Anthers truncate. Ovary 

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

 subulate stigma. " Follicles 4 in. long, ^ in. diam. above the narrowed base, rigid, like 

 poignards. Seeds ^- in., linear-oblong, silky, coma 4-5 times longer. Griffith's 

 plant is in very young flower and may be another species ; it has larger leaves with 

 fewer and very slender nerves. The Kangoon specimens have caudate-acuminate 

 leaves, larger bracts and hispidulous flowers. Kurz(in Journ. As. Soc. 1877, ii. 255) 

 refers this to U. esculenta. 



4. IT. malaccensis, Hook.f.-, quite glabrous except the inflorescence, 

 leaves elliptic or ovate-oblong obtusely caudate-acuminate coriaceous, nerves- 

 4-6 pairs slender, cymes shortly peduncled dense-fld., bracts puberulous oblong 

 obtuse, calyx-segments linear-oblong obtuse recurved, "follicles elongate fili- 

 form." 



MALACCA; Maingay (Kew Distrib. 1098, ? 1082). 



Branches smooth ; bark dark brown. Leaves 2-4 by 1-1^ in., smooth on both- 

 surfaces ; nerves arched, nervules obscure ; petiole | in. Cymes chiefly axillary ;. 

 peduncle glabrous, shorter or longer than the leaves ; bracts - in., recurved, much 

 larger than in the foregoing species ; flowers hoary rather than pubescent. Corolla- 

 us in the preceding species. Anthers obtuse. Ovaries hirsute ; style obconic, sur- 

 mounted with an obpyriform stigma. Follicles described by Maingay as " elongate- 

 filiform divaricate. Seeds oval, compressed, pilose at the apex." 



5. U. esculenta, Benth. in Gen. Plant, ii. 715; leaves elliptic caudate- 

 acuminate coriaceous, quite glabrous, nerves 9-11 pairs strong, follicles lanceolate 

 from a contracted peduncle-like base. Kurz For. Fl. ii. 184. Chavannesia
