Validity of the varietes of Senecio patagonicus (Asteraceae)

Abstract

The validity of the varieties of Senecio patagonicus Hook. & Arn. described by Cabrera is discussed. It is concluded that S. patagonicus var. alyssoides Cabrera and S. patagonicus var. lobatifolius (Hombr. & Jacquinot) Cabrera are synonyms of Senecio floccidus Hombr. & Jacquinot, and S. patagonicus var. andersonii (Hook. f.) Cabrera is synonym of Senecio arnottii Hook. f.
