sometimes tinged with red or purple, straight or somewhat falcate, 
slightly inequilateral, the base narrowed, acute or obtuse, not cordate, 
the apex rather slenderly long-acuminate, the acumen denticulate, margins 
distantly, irregularly dentate-lobed, the lobes small, broad, acute, the 
base 4- to 6-plinerved, the nerves ascending, the lateral ones above the 
basal nerves distant, 3 or 3 on each side of the midrib, ascending; 
petioles rather slender, about 5 mm long; stipules brown, membranaceous, 
deciduous, lanceolate, 1.5 to 3 cm long, the apex ciliate-acuminate. Stam- 
inate inflorescence terminal, paniculate, rather diffuse, 6 to 9 em long, 
the flowers small, pink, rather numerous, their pedicels 1 to 3 mm long. 
Sepals 2, ovate, obtuse or subacute, 5 mm long, faintly 7-nerved. Petals 
none. Stamens about 30, the anthers 1 mm long, the filaments much 
shorter. Bracts and bracteoles lanceolate, membranaceous, biown, acum- 
inate, deciduous, the former about 8 mm long, the latter 1.5 mm in length. 
Pistillate flowers not seen, apparently axillary at the base of the staminate 
inflorescence. Capsules solitary, nodding, obovoid in outline, their 
pedicels about 1 cm long, in the upper leaf-axils and at the base of the 
staminate inflorescences, equally 3-winged, the apex truncate, the base 
acute, about 1.8 cm long and wide, the wings about 5 mm wide. Placentae

A species manifestly allied to Begonia contracta Warb., but readily distin- 
guished from it and other allied forms by its leaves being more or less narrowed 
and acute or obtuse at the base, not at all cordate.
