Nomenclatural adjustments, new synonyms, and typifications in Senecio (Compositae) of the Chilean flora

Abstract

Thus far, the genus Senecio L. in Chile has only been thoroughly revised by the Argentinian botanist Cabrera, who published a monograph in 1949. He treated 11 names as dubious, 10 of which have remained unresolved until now. Herein, the taxonomic position of six names is elucidated, i.e., S. alsophilus Phil., S. araucanus Phil., S. leiophyllus Turcz., S. rufescens DC., S. simpsonii Phil., and S. tenuicaulis Phil. Moreover, the priority name for the illegitimate S. glaber Less. is indicated, the name S. botijae C. Ehrh. is synonymized with S. calcicola Meyen & Walp., and S. borchersii Phil. is synonymized with S. hakeifolius Bertero ex DC. The names S. araucanus, S. hakeifolius, S. leiophyllus, and S. tocornalii Phil. are lectotypified; likewise, S. alsophilus and S. simpsonii are neotypified.
