The genus Pauridia (Hypoxidaceae) amplified to include Hypoxis sect. Ianthe, Saniella and Spiloxene, with revised nomenclature and typification

Recent phylogenetic analyses show that the species of the southern African genera Pauridia, Saniella and Spiloxene and the Australian, Tasmanian and New Zealand Hypoxis sect. Ianthe form a highly supported, monophyletic clade. In keeping with earlier suggestions that these taxa doubtfully warrant separate status, and to avoid the recognition of Hypoxis and Spiloxene as paraphyletic, we expand the circumscription of Pauridia to include Saniella, Spiloxene and Hypoxis sect. Ianthe. As a result 33 new combinations at specific and infraspecific level are proposed and one epitype, two neotypes and 30 lectotypes are newly designated. Three basionyms, of which Linnaeus, Linnaeus filius and Lamarck are the authors, are also typified (Amaryllis capensis, Hypoxis aquatica, and Hypoxis pumila).
