Buddleja andina Britton ex Rusby (1895: 222)

Type (lectotype, designated here): BOLIVIA. La Paz: La Paz, 1889 (1885), H. H. Rusby 2050 ( NY barcode 297524! [digital image], isolectotypes BM barcode 600440! [digital image], MO barcode 391963! [digital image], NY barcode 297525! [digital image], WIS barcode v0256009 WIS! [digital image]).

Notes:—In the protologue of B. andina Rusby mentioned “Vic, La Paz, 10000 ft., 1889 (85) Rusby’s 2050”. In general this would be enough to point to a holotype specimen in NY, where N. Britton worked, were it not that there are two specimens (sheets) of Rusby 2050 in NY. One of these is here selected as the lectotype (Art. 9.17 of the ICN, McNeill et al. 2012, McNeill 2014).

Miguel Bang was a Danish botanist who collected mainly in Bolivia ( Stafleu & Cowan 1976) and whose plants are mostly at NY and US. There are several specimens collected by Bang number 85, from the same place and date as Rusby 2050, distributed to several herbaria ( BR, E, GH, K, NDG, NY, US). In 1889 Rusby and Bang agreed to collaborate to continue floristic studies in Bolivia ( Ochoa 1990). Although most probably Bang’s collection is a duplicate from Rusby’s, both have different collector and number, so to avoid ambiguity the Rusby 2050 is selected here as lectotype, in agreement with the protologue.

Current status:—heterotypic synonym of Buddleja aromatica Rémy (1847: 226) .
