A slender, scandent, glabrous plant growing on tree trunks. 
Leaves inequilateral, oblong-ovate, membranaceous, olivaceous, 
and shining when dry, 4 to 5 cm long, 1.5 to 2 cm wide, base 
rounded or obtuse, not at all cordate, apex acuminate, somewhat 
falcate, margins rather coarsely and irregularly toothed ; petioles 
about 5 mm long. Capsules axillary, usually in pairs, equally

Edano, August 8, 1917, in damp forests. 
This species belongs in the characteristic group of Begonia aequata A. 
Gray, the type of which was from Mount Maquiling, the other closely allied 
forms being Begonia wenzelii Merr., B. lagunensis Elm., and B. elegans 
Elm. It differs from Begonia aequata in its very much larger capsules, 
and from B. lagunensis Elm., to which it is also closely allied, in its very 
short petioles, and somewhat smaller, distinctly differently shaped capsules, 
which are not gradually narrowed below but which are abruptly rounded 
at the base.
