A species between C. Owariensis and C. Zairensis, remarkable 
for its leaves less peltate than the former, and clothed with 
eopious, villous, long, patent, yellow hairs, which also invest the 
petioles and branches ; the leaves are 4^ inches long, inches 
broad, on a petiole 2| inches long, inserted 4 lines within the 
margin of the basal sinus, which is 2 lines deep. The slender 
pilose raceme is 3 inehes long; the almost glabrous bracts, with 
very long ciliate margins, are 2 lines in diameter, very mem- 
branaceous, and reticulated.

This species is remarkable not only for its very tomentose 
leaves, less peltate than any of the preceding, but also for the 
very unusual form of its inflorescence and its heteromerous ^ 
flowers. The leaves, similar in both sexes, are 3^ inches long, 
2| inches broad, on a petiole 1^1| inch long, inserted 1^ line 
within the margin of the somewhat acute sinus, which is 2-3 lines 
deep. The (J raceme is 2-2f inches long ; its leafless axils, 
inch apart, bear a sessile agglomerate head of very numerous 
minute flowers, the heads being 2-3 lines in diameter. The ? 
raceme is 5-6 inehes long, with several lateral branchlets inch
