Moonlight, Peter & Fuentes, Alfredo F., 2022, AN UPDATED CHECKLIST AND KEY TO THE SPECIES OF BOLIVIAN BEGONIA, INCLUDING ONE NEW SPECIES, Edinburgh Journal of Botany 79 (407), pp. 1-66 : 55

Begonia micranthera var. venturii L.B.Sm. & B.G.Schub , Darwiniana 4: 97 (1941b).

R.C. Foster, Contr. Gray Herb. 184: 138 (1958); Delfini, C. in Zuloaga, F.O. & Belgrano, M.J. (eds), Fl. Argentina 17: 10 (2017).

Notes. This variety was included by Foster in his checklist of Bolivian Begonia ( Foster, 1958) but is endemic to Argentina ( Tebbitt et al., 2018a). Foster cited no specimens, so we cannot confirm to which taxon Foster misapplied this name.

Begonia micranthera var. foliosa L.B.Sm. & B.G.Schub. , Darwiniana 5: 92 (1941b).

R.C. Foster, Contr. Gray Herb. 184: 138 (1958).

Notes. This variety was described from Argentina by Smith & Schubert (1941b). A citation in their treatment of the begonias of Bolivia ( Smith & Schubert, 1944a) showed that they still considered it as endemic to Argentina, but Foster (1958) probably misinterpreted this citation and included the variety in his Bolivian checklist. Tebbitt (2020) shows that this variety is endemic to Argentina and is a hybrid between Begonia micranthera Griseb. subsp. micranthera and B. micranthera subsp. rhacophylla (Irmsch.) Tebbitt
