A rather striking species, distinguishable by its lanceolate, very slen- 
derly acuminate, more or less lacerate-lobed leaves which are narrowed 
to the subequilateral acute or obtuse bases. It is manifestly allied to 
- Begonia lancifolia Merr., but can be readily distinguished by its smaller, 
» . more narrowly lobed leaves, shorter petioles and stipules, subacute or 
obtuse sepals of the male flowers and fewer shorter anthers.
