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

 Follicles 6 by J in., quite straight, horizontal, eylindric, acuminate. Seeds linear^ 

 J in., softly Tillons, coma copious, four times longer. — The fruit figured and described 

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

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

 Aselepiadeous plant without flower or fhiit. 



2. V. Kaingrayl, Sook. f. ; quite glabrous except the inflorescence, 

 leaves elliptic abruptly acuminate thickly coriaceous, pale beneath, nerves 6-10> 

 pairs strong, cymes finely puhescent, csdyx-segments oblong' obtuse recurved,, 

 follicles cyfindric. 



SwQAPOBB, Maing^ay (Kew Distrib. 1083). 



Habit and brown colour of TJ. elastica, but the leaves are quite glabrous and 

 apparentlyglaucous beneath, with fewer more arched nerves not impressed above. The- 

 cymes are smaller, fewer and laxer-flowered ; the calyx-segments much broader and 

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

 more'slender in A. Maingayi. 



3. TJ. lucida, Benth. in Gen. PI. ii. 716 ; quite glabrous except the inflo- 

 rescence, leaves elliptic abruptly acuminate shining on both sm-faces, nerves 

 8-12 pairs, cymes lax-fld. finely pubescent, bracts subulate, calyx-segmenta 

 broadly oblong, follicles short gradually acuminate from a broad base. Cha- 

 vannesia lucida, A. DC. Prodr. viii. 444. Eehites ? lucida. Wall. Cat. 1670. 



Penang ; Wallich. ? Maxacca ; 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 obeonoid top surmounted by 

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

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

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

 fewer and very ^lender nerves. The Eangoon specimens have caudate-acuminate- 

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

 refers this to U. escttlenta. 



4. U. malaccensls, Sbok.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\ in., smooth on both 

 surfaces ; nerves arched, nervules obscure ; petiole \-^ in. Oymei chiefly axillary ; 

 peduncle glabrous, shorter or longer than the leaves ; bracts ^J 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 obconic, sur- 

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

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



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

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

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