right. Corona of 5 pouch-like folds at the base of the column alternating 1 with 

 the anthers, and 5 fleshy laterally compressed processes with free obtuse tips 

 adnate longitudinally to the backs of the anthers. Anthers large, horny, mem- 

 branous tips large oblong ; pollen-masses one in each cell, elongate, compressed, 

 falcate, with long pedicels, pendulous, waxy. Stigma, a depressed 5-angled 

 cone, included.

Contrib. 59 j Wall. Cat. 8230. 



NORTHERN CAMRTTP (Lower Assam), at Sanyashikata, in grassy hills, Hamilton. 



Stem 5-6 in., rigid, divided below. Leaves 4 by | in., spreading, exactly linear, 

 acute, base cordate, midrib stout, nerves faint ; petiole ^ in. Umbels clustered, 

 many-fld. ; pedicels \ in. ; bracts lanceolate. Sepals puberulous. Corolla i- in. 

 diam., purple within, glabrous. A very remarkable plant, of which the specimen in 

 Wallich's Herbarium (from which fragments were sent to Wight) is the only one 

 known. It is evidently near Holostemma and Asclepias itself. 



21. RAPHXSTEZKBXA, Watt. 



Twining glabrous shrubs. Leaves opposite, membranous. Cymes axillary, 

 umbelliform, long-peduneled ; flowers large, white, long-pedicelled. Calyx 

 5-glandular within. Corolla campanulate, 5-fid ; lobes spreading, twisted in 

 bud and overlapping to the right. Coronal-scalds 5, membranous, adnate to 

 the column, produced into long slender linear ligules. Column large, anthers 

 with an inflexed membranous tip ; pollen-masses one in each cell, not com- 

 pressed, pendulous, waxy. Stigma depressed, flat, 2-lobed in the middle. 

 Follicles thick, acute, smooth. Seeds couaose. DISTRIB. Species 2 ; Asiatic.

Branches slender, smooth, herbaceous. Leaves 3-7 in., sinus at base wide, midrib 

 glandular at the base above ; petiole 2-5 in. Cymes 4-6 fld. ; peduncle 4-5 in. ; 

 pedicels very slender, 1^-2 in. Sepals broad, very variable in size. Corolla thick, 

 pure white. Follicles (from a drawing) solitary? 6 by 1^ in. diam., sharply deflexed 

 from the very base, fusiform, turgid, terete, green, slightly upcurved. Wallich's 

 8221 B. from Finlayson seems to be E. Hooperianum, a native of Java and Siam. 



22. PENTATROPIS, Br. 



Twining slender herbs or undershrubs. Leaves opposite, small. Cymes 

 umbelliform, axillary ; pedicels slender. Flowers small, purplish. Calyx 5- 

 partite. Corolla rotate, 5-fid ; lobes elongate, overlapping to the right, twisted 

 to the left. Corona of 5 laterally compressed scales adnate vertically to the 

 backs of the anthers with free tips and spurred bases. Column short ; anther- 

 tips inflexed ; pollen-masses one in each cell, not compressed, pendulous, waxy. 

 Stigma hardly umbonate. Follicles smooth. Seeds cornose. DISTKIB. Species
