CONTRIBUTIONS TO BOTANY.

both obtained by me in Rio de Janeiro. They likewise pronounce 
it to be identical with the Cissampelos ovata of the ‘ Flora Flu- 
minensis/ x. t. 141, which appears to me very doubtful; while, 
on the other hand, MM. St. Hilaire and Tulasne declare their 
Cocculus Martii to be the same as the Cissampelos tomentosa of 
the same work, which agrees with my own observations. The 
Cissampelos ovata, Velloz, above mentioned appears to me to 
partake more of the characters of a Chondodendron : the flowers 
are larger than in any species of Abuta I have met with, the 
sepals being refracted as in the former genus, while the panicle 
is much shorter and more spreading than in Abuta', in habit 
and inflorescence it harmonizes with the several species of Chon- 
dodendron which I have described from near the same locality 
where Velloz’s plants were collected. DeCandolle described his 
plant as having leaves 2-3 inches long, and drupes 1 inch long. 
In M. Sagot’s specimen the leaves are 4|-5 inches long, 3|- 
4^ inches broad, on a strong petiole 2-2| inches long.

The leaves in this species vary very much in size and shape ; 
but in all their different forms they have an aspect very different 
from the preceding ; they are very convex, and never flat as in 
the typical plant ; they are more coriaceous than in that and the 
following species ; they have a shagreened surface above, owing 
to the minuteness of the prominent reticulations ; the margins, 
very revolute and thickened by a prominent nervure, are quite 
smooth above, except in the channelled nerves and transverse 
veins, which are tomentose ; they are densely tomentose beneath, 
and have very prominent strong nerves and an extremely short 
acute point at the rounded summit, which is sometimes wanting. 
There is a difference in the mode of nervation of the leaves in
