DC,, Cuba (Linden, 1809) ; in herb. Mus. Brit,, Jamaica 
(Shakespear). 
The above plants quite accord with DeCandolle’s species from 
Campeche : all are scandent, and distinguished for their rather 
small, thick, and almost fleshy leaves, in which respect they 
diflfer from the plant described by Kunth under the same name. 
The axils are about 1^ inch apart; the orbicular leaves, densely 
clothed with thick yellowish tomentum, are generally crispately 
undulating on the margin, 1^-1^ inch in diam., with a stout 
petiole ^-1 inch long, inserted barely 1 line within the basal 
margin. The very tomentose panicles are 1 inch long and broad, 
the peduncle being 5 lines long, and it becomes divided trichoto- 
mously into short branches, with a pedicellated small head of 
flowers in each sinus, the ultimate branches bearing a similar 
head of flowers; the floriferous raceme-like branch is 1-lf inch 
long, with axils 3 lines apart, each axil producing a leaf-shaped 
petiolulated bract 2-5 lines in diameter, and one or two panicles 
2-3 lines long.

tero, 569). 
The above plant seems to correspond with the ^ plant described 
by Miquel : its branches are very slender; the leaves are 12-17 
lines long, 12-16 lines broad, with a basal sinus 1^-2 lines deep, 
on a slender petiole 7-9 lines long, inserted \ line within the 
margin. The ? raceme is 3^ inehes long, with rounded tomen- 
tose bracts 2-3 lines apart and 2-3| lines in diameter.
