Nomenclatural notes. The typification of Begonia veitchii and its synonyms was covered in depth by Tebbitt et al. (2020). Several previous authors (Smith & Schubert, 1944a; Foster, 1958; Wasshausen et al., 2013) cited the author of Begonia baumannii Lemoine as “Lem”, which is the standard form for Antoine Charles Lemaire, who died in 1872, 18 years before B. baumannii was published. Similarly, most authors who have applied the name Begonia fulgens in Bolivia (see Excluded names) have cited the authorship as “ Begonia fulgens

Lem.” The author of Begonia baumannii and B. fulgens was Victor Lemoine, so B. baumannii Lemoine and B. fulgens Lemoine are the correct author citations for these names, respectively.

Identification notes. Begonia veitchii is among the most common tuberous Bolivian Begonia species. It is easily distinguished from the remainder of Bolivian Begonia sect. Australes in having symmetrical leaf laminae that lack a distinct apex. It is also the only member of its section that is frequently acaulescent. Members of Begonia sect. Eupetalum are also acaulescent and tuberous and often lack a distinct apex to their leaves, but all Bolivian species differ in having more than five tepals on their staminate flowers.
