diametro; capsulis circiter 1 cm longis et 1.8 cm latis, inaequi- 

 lateraliter 3-alatis. 



A subglabrous herb, the stems creeping, reddish-brown when 

 dry, about 1 cm in diameter, glabrous ; stipules deciduous, broadly 

 ovate, acuminate, sparingly ferruginous-ciliate, about 1 cm long. 

 Leaves prominently peltate, the petiole inserted 2 to 4 cm from 

 the base of the leaf, membranaceous, somewhat oblique, ovate to 

 oblong-ovate, 15 to 20 cm long, 10 to 12 cm wide, base broadly 

 rounded, apex acute or somewhat obtuse, margins subentire, not 

 £t all lobed, with a fringe of scattered, tooth-like, short cilia, 

 both surfaces with widely scattered, short hairs, ultimately 

 glabrous or nearly so ; basal nerves radiate, about 9, prominent, 

 the reticulations very prominent on the lower surface; petioles 

 12 to 15 cm long, glabrous or with very few, widely scattered, 

 short hairs. Inflorescences 25 to 35 cm long, dichotomous, few- 

 flowered, sparingly ciliate with short, pale, spreading, scattered 

 hairs, the flower-bearing part about 10 cm long. Staminate 

 flowers white or slightly pink, about 2 cm in diameter, the sepals 

 elliptic-ovate, rounded. Capsules about 1 cm long and 1.8 cm 

 wide, base rounded, apex subtruncate, one wing very much larger 

 than the other two and about 1 cm in width, the other two 3 

 to 4 mm wide.

This strongly characterized species is one of the few known represen- 

 tatives of the section Diploclinium with peltate leaves. It is readily dis- 

 tinguished from our peltate-leaved species, Begonia hernandioides Merr., 

 B. rufipila Merr., and B. ELMERI Merr. [B. peltata Elm. Leafl. Philip. Bot. 

 7 (1915) 2556, non A. DC, nee Hassk., nee Otto & Dietr.] by being nearly 

 glabrous, the few, widely scattered hairs on the leaves and inflorescences 

 scarcely exceeding 1 mm in length.
