stems at least 15 cm long, the branches 1.5 to 5 cm long, slender, 
sparingly appressed hirsute. Leaves suborbicular to orbicular- 
obovate, inequilateral, 5 to 138 mm long, brownish when dry, the 
apex rounded or obtuse, base strongly inequilateral and shal- 
lowly laterally cordate, entire below, the upper two-thirds on the 
broader side with about 4 rounded teeth, the narrower side in 
the upper one-third with 2 or 3 similar teeth, upper surface with 
irregularly scattered, distinct, elongated cystoliths, these obso- 
lete on the lower surface; stipules oblong-elliptic, membrana- 
ceous, glabrous, usually obtuse to acute, 3 mm long. Staminate 
receptacles axillary, solitary, sessile, about 5 mm in diameter ; 
bracts broadly obovate, about 5 mm long, sparingly hirsute, prom- 
inently keeled, scarcely corniculate, the apex broadly rounded, 
the inner ones thinner, somewhat hirsute, truncate, keeled, as 
long as the outer ones, about one-half as wide; bracteoles mem- 
branaceous, hirsute, oblong-spatulate, narrowly oblong-obovate, 
4 mm long, obtuse; sepals oblong-elliptic, membranaceous, about

The alliance of this species is with Elatostema obovatum
