This species differs from C. ovalifolia in the orbicular shape 
of its leaves, their more velvety covering, and their longer pe- 
tiole ; from C. vestita for the same reasons and the very different 
form and size of the leaves in the ^ plant. It is probably the 
C. rotunda of Fohl, a manuscript name given to a plant of his 
collection, which is perhaps identical with Claussen^s specimen. 
The axils are scarcely f inch apart ; the leaves, somewhat divari- 
cating, sometimes refracted, are 2-2| inches long, 2^-2| inches 
broad, on a stout petiole, geniculated on the margin of the blade; 
the capillary peduncle of the panicle is 6 lines long, and bears 
three to five short, approximated and almost umbellate rays, 
with numerous corymbose pedicels | line long ; the sepals, 1 line 
long, are spathulately obovate and obtuse, the cup-shaped petal 
one-third that length, all pilose outside. The ? raceme is 2 inches 
long, with membranaceous orbicular bracts, truncated at base, 
round at the apex, 3 lines apart, 4-5 lines broad, 3-4 lines long, 
on a petiolule f line long, each with about four fasciculated very 
small flowers; ovary very villous; the stigmata are short, diva- 
ricated, and with the style, glabrous. 
This and all the kindred erect species are known in Brazil by 
the name of Orelha de Onqa (Tiger’s ear) ; in the Spanish regions 
they are called Oreja de Burro (Ass’s ear), not Bull’s ear, as it 
is translated in Mart. FI. Brasiliensis.
