Identification notes. Begonia cremnophila is only acaulescent species of Begonia confirmed from Bolivia with a basifixed, asymmetrical leaf lamina and four tepals on the staminate flower. It is most similar to an undescribed species from Puno Region, Peru, which may also occur in northern Bolivia (Moonlight et al., in review). It differs from this species in its pilose indumentum on the veins of the underside of the leaf (vs glabrous); its obovate bracts with denticulate, ciliate margins (vs lanceolate with entire margins); and its tepals that persist in fruit.
