Baccharis lanuginosa Gardner (1848: 82) . —Type: “Dry bushy places between Villa do Principe and Cocaes”. BRAZIL. Minas Gerais: [between Serro and Arraial dos Cocais, between 18 th and 26 th August 1840, fide Hind, pers. comm.], Sept. 1840, ♀, G. Gardner 4900/1 (holotype BM (000756675) photo!).

Barroso (1976) only indicated Sellow d2013 as “ holotype ” of B. helichrysoides , without citing any herbarium acronym. Although effectively a lectotypification, her choice was superseded owing to a previous lectotypification by Malagarriga (1957) based on the same material in P. The holotype of B. lanuginosa is stated as being from September 1840 on the type specimen sheet. However, Gardner (1848) wrote ‘ Aug. 1840 ’ in the protologue and cited the collection as ‘4900,1’. In the ‘Catalogue’ of his collections, the entry of B. lanuginosa was clearly added relatively late when Gardner realized he had a ‘new species’ (Hind, pers. comm.).
