Notes. Begonia peruviana was included in the checklist of Bolivian Begonia ( Wasshausen et al., 2013) based on a single specimen. We include three further specimens of this species from Bolivia, all from La Paz Department.

Nomenclatural notes. We refrain from designating a lectotype of Begonia peruviana here.

We will designate a lectotype in an upcoming treatment of the Begonia of Peru, which will also include new synonyms of B. peruviana and a full discussion of their nomenclature (Moonlight et al., in review).

Identification notes. Like the other members of Begonia sect. Ruizopavonia , B. peruviana is a semi-scandent species with oblong leaves and pinnate venation. It is unique among glabrous Bolivian members of the section in its deciduous stipules. Begonia peruviana , B. comata and B. oblanceolata are the only glabrous members of the section in Bolivia, and B. peruviana can be distinguished by the distinct (rather than indistinct) secondary veins on the leaf lamina.
