the sinus rather narrow, acute, 1 to 1.5 cm deep, both lobes rounded, 
one much boader than the other, not superposed, apex prominently and 
sharply acuminate, the acumen usually about 1.5 cm long, margins dis- 
tinctly distantly and irregularly crenate-dentate, frequently also with 
few, small lobes which are broader than -long, the upper surface, at least 
when young, with scattered, long, brown hairs, ultimately becoming nearly 
glabrous, on the lower surface similar hair? more numerous and per- 
sistent, the margins prominently ciliate with long brown hairs; base 
palmately 7- to 9-nerved; petiole 5 to 20 em long, distinctly villous with 
long, slender, brown hairs. Peduncles as long as or exceeding the leaves, 
with few to many long, ciliate, brown hairs, dichotomously branched at 
the apex, the branched part of the inflorescence about 5 cm long, rather few- 
flowered. Flowers white, the staminate ones about 2.5 cm in diameter, 
the slender pedicels 2 cm in length. Sepals 2, broadly elliptic, rounded

A species manifestly allied to Begonia trichocheila Warb., and to B. longo- 
villosaA. DC, diflfering from the former in its prominently and sharp y acummate 
leaves which are more or less toothed, not entire, and distinctly villous on both 
surface!' ith long, brown hairs, and from the latter in its differently shaped 
Tpules, iuite diff;rently shaped leaves, longer petioles, and other characters.

A. DeCandolle to Begonia maniUensts.
