rather coarsely dentate-serrate, usually 10 to 12 teeth on each 
side, the upper surface glabrous, with numerous, irregularly dis- 
posed, elongated cystoliths; petioles 2 mm long or less; stipules 
lanceolate, about 8 mm long. Staminate receptacles axillary, 
solitary, sessile, globose, 6 to 8 mm in diameter, the two external 
bracts orbicular, somewhat ciliate, broadly rounded, prominently 
corniculate, the appendage 2 to 3 mm long; bracteoles variable, 
oblong to oblanceolate, membranaceous, 4 to 5 mm long, pro- 
minently ciliate with long white hairs and with a very slender, 
ciliate, 2 to 3 mm long appendage from the back at or above the 
middle. Sepals of the staminate flowers 4, membranaceous, 
ciliate above, 2 to 2.5 mm long, two of them distinctly corniculate.

The alliance of this species is not entirely clear, although, 
with the exception of the indumentum and its bract and floral 
characters, it resembles Elatostema carinoi W. R. Shaw. It is 
readily distinguished by its laxly reticulate leaves, the nerves 
and reticulations being dark brown in contrast to the green epi- 
dermis, and distinctly ciliate, as well as by its peculiarly append- 
aged bracteoles.

An erect, apparently unbranched, woody plant, at least 50 
cm high, the stems nearly glabrous below, above more or less 
pilose with rather long spreading hairs. Leaves chartaceous or 
subcoriaceous, inequilateral, oblong-ovate, about 15 cm long and 
6 cm wide, dark brown when dry, the upper surface with nu- 
merous, irregularly disposed, short cystoliths, the lower surface 
softly pilose with rather long spreading hairs on the nerves and 
reticulations, apex slenderly acuminate, base narrowed, inequi- 
lateral, rounded on the broader side, acute or somewhat rounded 
on the narrower side, the more prominent nerve on the narrower 
side leaving the midrib well above the base, margins distantly
