Nomenclatural notes. The protologue of Begonia andina Rusby cited the collection R.S. Williams 1566 but did not mention a herbarium ( Rusby, 1912). Smith & Schubert (1944a) cited the type as in New York herbarium, which is an effective lectotypification of the name. The protologue also cited a collection made by Richard Spruce in Chimborazo Province, Ecuador, in June 1860 as the same species. The only sheet we know of that matches this description is a collection of Begonia holtonis A.DC. , which is a superficially similar but distantly related species ( Moonlight et al., 2018).

Identification notes. Begonia andina is an easy species to determine on account of the densely tomentose-stellate indumentum on its stems, petioles, and the underside of its leaves, which is unique among Bolivian Begonia species.
