Herba parva omnibus partibus praesertim jimioribxis plus minus dense 
f errugineo-pilosis ; foliis inaequilateraliter anguste ovatis vel oblongo- 
ovatis, usque ad 4 cm longis, integris, acutis vel leviter acuminatis, basi 
leviter oblique cordatis; pedunculis quam folia longioribus, paucifloris; 
floribus 2.6 cm diametro; eapsulis circiter 1.5 cm longis^ inaequaliter

Small herb, the stems postrate^ creeping^ with numerous, long, slender, 
brown, ciliate hairs, and with ovate, brown stipules. Leaves inequilater- 
ally oblong-ovate or narrowly oblong, entire, 2 to 4 cm long, 1.8 to 2.7 
cm wide, the apex acute or obscurely acuminate, the base slightly and 
obliquely cordate, the lobes rounded, the sinus narrow, acute, both surfaces 
with scattered, long, brown, slender hairs, the margins also ciliate with 
similar ones, the base palmately 4- or 5-nen^ed, the nerves faint ; petioles 
2 to 5 cm long, brown-ciliate, tlie hairs, as in other parts of the plant, 
slender, often 4 to 5 mm long. Inflorescence slightly longer than the 
leaves, the peduncle more or less brown-ciliate, bearing few flowers. 
Plowers apparently pink, the staminate ones 2.6 cm in diameter. Sepals

A species manifestly allied to Begonia longoviUosa A. DC, B. klemmei Merr.,
