and laterally cordate, the margins coarsely dentate-serrate, 
the teeth on the broader side 8 to 10, on the narrower side 4 
to 6; nerves and reticulations prominent on the lower surface, 
the latter lax, brownish, the base 3-plinerved. Pistillate and 
staminate receptacles axillary, solitary, sessile, 8 to 10 mm in 
diameter. Outer bracts rounded to reniform, glabrous, not 
at all corniculate, the inner ones obovate to oblong-obovate; 
bracteoles spatulate, membranaceous, 3 to 4 mm long, slightly 
ciliate above. Sepals of the staminate flowers membranaceous, 
2 to 2.5 mm long, two of them distinctly corniculate.

This species is most strikingly characterized by its very di- 
verse leaves, which vary enormously in size, even on the same 
plant; in the larger specimens they are as much as 9 cm long 
and 4 cm wide, but on some of the smaller specimens and on the 
branches they are very much smaller, sometimes not more than 
1 cm long and wide. The general alliance of the species appears 
to be with Elatostema carinoi W. R. Shaw. .
