This species appears confined to Guiana and northern Brazil ; 
it much resembles C. ovalifolia in the hue and texture of its 
leaves, but diflFers in their more orbicular form, usually deeply 
crenated margin, and in their still shorter petiole. It is a plant 
growing in arid savannas, apparently of very low stature, with a 
simple erect stem 2 lines thick, and with axils f-l^ inch apart; 
the leaves in the are 1|-1J inch long, 1^-1 i inch broad, on a 
petiole 1 line long; in the $ they are 2-2^ inches long, l|-2;^ 
inches broad, with a thick petiole 1 line long; two or three 
panicles, about 1 inch long, are fasciculated in each axil, the 
pilose peduncle, | inch long, being alternately ramified, with 
extremely short branches, on which the corymbose minute 
flowers are approximated in a subcapitate head. There is a dis- 
position to deformity in the flowers, which have sometimes an 
additional sepal, or two flowers are metamorphously combined, 
thus showing eight or fewer sepals in a double series, with one 
or two petals and stamens. The $ racemes are about inch 
long, the bracts being 3 lines in diameter.
