BURMA ; at Segaen, Wallich. 



Leaves in distant pairs, H-2J? by 1-1^ in., very membranous, acuminate ; basal 

 lobes rounded, incurved with a broad sinus; nerves very slender; petiole 1-1 in. 

 filiform. Cymes puberulous ; peduncles shorter than the petioles, pedicels ^-^ in. 

 Sepals half as long as the corolla, which is % in. long, pale and quite glabrous inside 

 and out. I find no traces of the 5-fid tubular corona at the base of the stipes of the 

 column described by Wight.

 axillary, few-fld. ; flowers large, purple. Sepals eglandular. Corolla subrotate ; 

 lobes thick, ovate, overlapping to the right. Corona low, annular, 10-lobed, 

 fleshy. Anthers very large, oblong, horny, shining, cohering in a 10-winged 

 column, tip small inflexed membranous ; pollen-masses one in each cell, elongate, 

 falcate, compressed, pendulous, waxy, pedicels long black. Stigma included,

Quite glabrous, or the leaves faintly puberulous. Leaves 3-6 in., basal lobes 

 spreading or incurved and meeting ; petiole 1-3 in., glandular at the base of the mid- 

 rib above. Cymes umbelliform or in irregular racemes ; peduncles 1-2 in.; pedicels 

 as long. Corolla 1-1 in. diam. ; lobes subacute, incurved, white on the back and 

 margin. Follicles, according to Rheede's figure, like those of Raphistemma. Sprengel 

 is given as the authority for the name H. Rheedei, on the supposition that it is his H. 

 Rheedianum, which being described as erect with oblong cuspidate strongly nerved 

 leaves must be a very different plant. As Sprengel's other species, H. Candolleana, 

 is a Fischeria, his genus must be abandoned. 



26. CYNANCHUM, Linn. 



Erect or twining herbs or shrubs. Leaves opposite, rarely whorled. Cymes 

 axillary, umbelliform racemose or subpaniculate ; flowers small, greenish or 

 purplish. Calyx 6-partite. Corolla rotate, 5-partite, lobes overlapping to the 

 right or valvate. Corona adnate to the base of the column, 5-partite or cupular 

 or campanulate, variously toothed or lobed, with or without scales or tubercles on 

 the inner face opposite the lobes. Anthers sessile or stipitate, tip membranous 

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

 Stigma flat, unabonate or apiculate. Follicles terete or shortly 2-wiuged, elon-
