Distribution and Habitat ( Fig. 5 View FIGURE 5 ): — Senecio canescens occurs in the Andes of Colombia to Bolivia, at elevations of 3000–5000 m.

Note: — Cuatrecasas (1951) mentioned in the protologue of Senecio canescens var. ecuadoriensis that its type specimen is Hitchcock 21059 ( NY, US). We were not able to find any material with this number in NY or US ; we found a specimen at NY that corresponds to the protologue ( Mount Pichincha near Quito, 4100–4500 m), with Cuatrecasas’ revision label which indicates that it is an isotype, although with a different number Hitchcock 21054. Therefore, we conclude that there must have been a typographical error, and type collection number is indeed Hitchcock 21054 .
