racemo ? axillari, folio longiore, bracteato ; bracteis vix imbri- 
catis, suborbiciilaribus, fere sessilibus, pubescentibus. — In 
Ecuador et Antillis : v. s, in herb. Mus. Brit., DC., et Hook., 
, Guayaquil (Jameson, 335) ; in herb. Hook., Guayaquil 
(Spruce, 6322) ; in hb. Mus. Brit. $ , sine loco (Aublet) ; 
in hb. DC. ? , Mexico (Pavon), Cuba (Poppig). 
The $ plants have all a different aspect, with more deltoid 
leaves ; but I have referred them here, as they correspond pretty 
well with the type. They are all extremely slender climbers, 
with nearly orbicular leaves, almost glabrous above, more or less 
tomentose below, with a marginal fringe of yellow silky hairs ; 
the leaves are 1-2 inches long, 18-2^ inches broad, on a very 
slender petiole |-lj inch long, inserted 1 line within the mar- 
gin ; the panicles are f inch long, with short linear bractlets 
at their several ramifications; the ? raceme is inch long, 
with bracts (scarcely imbricated) 2 lines in diam. ; in the plant 
from Mexico the raceme is 2-2^ inches long, with bracts 3 lines 
in diameter.

utrinque retusis et constrictis, apice obtusis, emarginatis et 
mucronatis, 7-nerviis, supra nitidulis, sparse pubescentibus,

Tweedie notes that this is a lofty climber, which densely covers 
the branches of the trees on which it grows, producing a dark 
shelter beneath them; the branches are slender and twining, 
with axils about 1| inch apart; the leaves are 2-2^ inches long, 
2^-2^ inches wide, with a broad basal sinus 2 or 3 lines deep, 
on a petiole 1 inch long, inserted 1 line within the margin ; 
the axillary ^ floriferous branch is 1 inch long, doubtless becom-
