It offers the same relation to C. convolmlacea that the American 
species C. longipes bears to C. Pareira. In the ^ specimens 
with larger leaves, the latter are more orbicular, 3|-4 inches 
long, 4-4^ inches broad, on a petiole 3-3 j inches long, inserted 
4 lines within the margin of the shallow, broad basal sinus. In 
most of the Wallichian specimens the leaves are more deltoid, 
2^-2| inches long, 2^-2f inches broad, on petioles 2|-4 inches 
long, which are inserted 4 lines within the basal margin. In 
the Ceylon plants they are lf-2| inches long and broad, on a 
very slender petiole 2;j-2| inches long, inserted 2 lines within 
the margin. The ^ panicles are seldom more than | inch long : 
the 2 racemes 1-3 inches long, with imbricating bracts 2-4 lines 
in diameter.

This is a more slender plant than most of the preceding spe- 
cies, with smaller, more triangular, pointed, heart-shaped leaves 
of thinner texture, and with a more slender and shorter petiole. 
The leaves are 3| inches long (including the basal sinus | inch 
deep), 3f inches broad, the petiole (1^ inch long), suddenly re- 
curved at base, being inserted 4 lines within the margin of the 
sinus : some younger leaves are 2j inches long, 2 inches broad, 
with a basal sinus 4 lines deep and a petiole 1^ inch long, which 
is inserted 2^ lines within the margin. The ^ panicles, shorter 
than the petioles, have a very slender peduncle 6 or 7 lines long, 
its branches being 2 lines. The 2 raceme is 1 inch long, with 
leaf-shaped bracts 3 lines in diameter, the axils bearing four or
