''Beauverdia'' is a genus of South American plants in the onion subfamily within Amaryllis family, native to Brazil, Uruguay, and Argentina.〔(Tropicos, ''Beauverdia'' Herter )〕 The plants are bulb-forming perennial herbs. Affinities and classification of the species are unresolved at present, and require additional investigation. In 1972, genus ''Ipheion'' was divided into two sections, ''Hirtellum'' and ''Ipheion''. However, the development of phylogenetic analysis revealed that ''Ipheion'' was not monophyletic, although the division into sections was later supported. ''Beauverdia'' Herter had been first described in 1943 as a genus with 10 species.〔 Originally it was created to distinguish those species with single-flowered inflorescences from others with many-flowered inflorescences within ''Nothoscordum'' and other genera, some of them no longer considered members of the Amaryllidaceae. Some authors declined to regard the group as a distinct genus, preferring to consider the name a synonym of ''Ipheion.'' A number of species were transferred to other genera, including ''Nothoscordum'' and ''Tristagma''.〔 In 2014, ''Beauverdia'' was again raised to genus rank and restored to the tribe, with four species.〔Sassone, A.B., Giussani, L.M. & Guaglianone, E.R.
