Begonia andina Rusby, Bull. New York Bot. Gard. 8: 108 (1912). – Type: Bolivia , [ La Paz Department], Santa Barbara , [ 14°44′S , 68°37′W ], 5000 ft , 30 viii 1902 , R.S. Williams 1566 ( lectotype NY [ NY00112290 ] designated in: Revista Univ. (Cuzco) 33(87): 81 (1944) by Smith, L.B. & Schubert, B.G.; isolectotypes BM [ BM001191441 ], K [ K000322980 ], US [ US00115238 ] ). L.B. Smith & B.G. Schubert , Revista Univ. ( Cuzco ) 33(87): 81 (1944) ; L.J. Dorr , Brittonia 43(4): 223 (1991) ; D.C. Wasshausen et al. in P.M. JØrgensen et al. (eds), Cat. Bolivia , Monogr. Syst. Bot. Missouri Bot. Gard. 127: 383 (2013) . Distribution . Endemic to Bolivia and La Paz Department. 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.
