campanulate, glabrous, shortly 5-lobed ; lobes. erecto-patent, overlapping to the 
right. Corona 0. Column very shortly stipitate, conical, 5-angied; anthers

Leaves in distant pairs, 14-2} 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 45-4 in. 
Sepals half as long as the corolla, which is à 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.

Twining glabrous shrubs. eaves opposite, membranous, cordate. Cymes 
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 intlexed membranous ; pollen-masses one in each cell, elongate, 
falcate, compressed, pendulous, waxy, pedicels long black. Stigma included, 
5-winged. follicles short, thick, smooth, acute. Seeds comose. —DISTRIB. Two

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. /heedei, 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. eaves opposite, rarely whorled. Cymes 
axillary, umbelliform racemose or subpaniculate ; flowers small, greenish or 
purplish. Calyx £-partite. Corolla rotate, 5-partite, lobes overlapping to the 
right or valvate. Corona adnate to the base of the column, 6 arte or cupular 
or campenulate, 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.
