pale yellow flowers, on pedicels 6 lines long; sepals acute, 1-14 line long; tube of 
corolla narrowly cylindrical towards the base and near the summit, where it is spirally 
twisted, ventricose in the middle, 15 lines long, subpilose within ; segments obovately 
dolabriform, crispate on the margins, 7 lines long and broad, with dextrorse convo- 
lution ; stamens inserted on a pilose ring on the lower constriction of the tube; disk of 
5 oblong fleshy lobes, half the length of the 2 ovate glabrous ovaries; follicles 2, terete, 
horizontally divaricate, outwardly subarcuate, 8 in. long, 3 lines thick towards the base, 
obtuse, and 2 lines thick towards the apex; seeds many, oblong, dorsally costate, thinly

This marked species is well depicted by Jacquin and Plumier, and is very different 
from the plant described by Kunth. In Jamaica it grows in the moist parts of the 
savanna. It is a twining plant, climbing to a height of 15 feet, exuding a clear, glu- 
tinous and poisonous juice; its branchlets are slender, glabrous, with axils 4 in. apart ; 
leaves oblong, deeply cordate at the base, subacute at the summit, dark green above, with 
about 14 pairs of patently divaricate nerves arcuately conjoined near the undulate 
margin, pale ferruginous beneath, with prominulent nerves and reticulated veins, 31-4 
in. long, 11-2 in. broad, on petioles 5 lines long; inflorescence lateral, on a peduncle 
1$ in. long, supporting 4-7 flowers on umbellate pedicels 6 lines long, pluribracteolate 
at their base; sepals acute or acuminate, 13 line long, each with 2 acute inner scales ; 
tube of corolla 12-15 lines long, narrowly cylindrical at the base and summit for a length 
of 5 lines, there spirally twisted, longitudinally 5-nerved, of a greenish colour; segments 
white, deltoidly dolabriform, with crenulate margins, 7 lines long and broad, dextrorsely 
convolute; stamens on very short filaments, seated on the lower constriction of the tube; 
disk of 5 fleshy oblong lobes, shorter than the 2 conical ovaries; follicles 2, terete, ob- 
long, horizontally divaricate, obtuse, 8 in. long, 4 lines thick, containing many oblong 
seeds thinly rostrate at the apex, 6 lines long, surmounted by an erect apical com 
9 lines long.

A climbing species with terete branches, having its axils 14 in. apart ; opposite leaves 
suborbicular, roundish at the base, retuse, with a very short acute acumen at » E 
mit, rigidly membranaceous, darkish green above, with many parallel, oblique, divergent 
nerves and reticulated veins, beneath opake, paler, pruinose, with prominent nerves, 
2-21 in. long, 14-2 in. broad, on petioles 4-6 lines long; raceme lateral at the nodes, on 
an erect peduncle 3-1 in. long, supporting 4-5 flowers on subumbellate pedicels 6 lines
