 Nomenclatural notes. In the protologue of Begonia williamsii Rusby & Nash (1906: 47), the authors cited material collected by R. S. Williams north of San Buena Ventura in Bolivia between 1901 and 1902. In their account of the Begoniaceae of Bolivia, Smith & Schubert (1944a) cited a sheet of R.S. Williams 600 in New York as the type of this name. There is only one sheet matching this description in the New York Botanical Garden herbarium, so this counts as an effective lectotypification. This proceeds an attempt by Tebbitt et al. (2018b) to lectotypify Begonia williamsii, thus Smith and Schubert’s earlier typification should be followed (see Article 9.19 of the Shenzhen Code; Turland et al., 2018).   
 Identification notes. In Bolivia, Begonia wollnyi is most likely to be confused with either B. acerifolia or B. leathermaniae. It can be distinguished from the former species by its usually basifixed leaves and its three, well-developed wings on its ovaries and fruits (vs two wings reduced to small, rib-like projections). Begonia leathermaniae is best distinguished by its ring of trichomes where its petiole joins the leaf lamina.
