Typification notes

To clear up confusion surrounding the typification of B. weddelliana , we designated a lectotype for this name. The species was described with no herbarium cited for the type collection, but Tebbitt (2013) stated that a holotype was found in G-DC with an isotype in P. This is incorrect according to the nomenclatural code ( Turland et al. 2018) as when no herbarium is cited all duplicates are syntypes ( McNeill 2014). The duplicate in P includes six, more or less complete plants whereas the duplicate in G-DC contains only a single leaf removed by de Candolle from the duplicate in Paris. Accordingly, we designate the P duplicate as the lectotype.

Notes

Begonia davisii Hook. f. was described from living plants collected by J. Veitch near Chupe at ca 10 000 ft, and this locality was stated as being in Peru ( de Candolle 1859: 122). In fact, Chupe is in La Paz Department, Bolivia and B. weddelliana A.DC. , of which B. davisii is a synonym, is endemic to Bolivia ( Tebbitt 2013).
