An erect, simple or sparingly branched herb, 15 to 40 cm high, 

 the basal parts of the stems often prostrate and rooting, the 

 stems and branches subappressed-hirsute. Leaves membra- 

 naceous and olivaceous when dry, inequilateral, oblong-obovate, 

 2.5 to 7 cm long, 1.5 to 4 cm wide, sessile or subsessile, the apex 

 rounded to acute, the terminal tooth usually acute, the broader 

 side with 8 to 10, prominent, acute teeth, the narrower side 

 usually with about 5 similar teeth, the margins in the lower 

 one-half entire, base auriculate-rounded on the broader side, 

 acute on the narrower side, somewhat obliquely cordate, the 

 upper surface with numerous, conspicuous, irregularly arranged 

 cystoliths, sometimes with a few long hairs, more often glab- 

 rous, the lower surface appressed-hirsute on the conspicuous 

 nerves and reticulations, the cystoliths obscure or obsolete; 

 petioles 2 mm long or less, appressed-hirsute; stipules membra- 

 naceous, oblong, glabrous, about 5 mm long. Staminate inflo- 

 rescences in full anthesis 1 to 1.5 cm in diameter, their pedicels 

 slender, glabrous, 1 to 1.5 cm long; outer bracts very broadly 

 ovate, about 7 mm long, 6 mm wide, conspicuously corniculate, 

 the apical projection 1.5 to 2.5 mm long, the margins ciliate, 

 the inner bracts oblong-obovate, apiculate, 2.^ mm wide; brac- 

 teoles spatulate, membranaceous, 4 to 5 mm long, 1 to 1.5 mm 

 wide, ciliate. Staminate flowers 4-merous, very numerous, their 

 pedicels 4 to 5 mm long. Sepals elliptic to elliptic-ovate, 2 to 2.3 

 mm long, with a few long white hairs near the apex, two of 

 them minutely cucullate and obscurely apiculate. Pistillate inflo-
