Gard. 129: 386 (2013) . Distribution . Endemic to Bolivia . Nomenclatural notes . The protologue of Begonia unilateralis Rusby cited the collection G.H.H. Tate 657 but no herbarium ( Rusby, 1934 ). Smith & Schubert (1944a) cited a sheet of this collection in the New York Botanical Garden herbarium as the type . Only one sheet in New York matches this description, so this is an effective lectotypification. Identification notes . This is the only species of Begonia in Bolivia with an indumentum of peltate scales.
