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, g-Iabrous, not 

 at all comiculate, 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. 



Mindanao, Zamboanga District, mountains back of Zam- 

 boanga, Merrill 9127, December 6, 1911, in damp shaded ravines 

 along small streams on banks and ledges, altitude 200 to 400 

 meters. 



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.
