Tribe Notocacteae Buxb. :

—The Notocacteae had long been a heterogeneous group of South American genera ( Parodia Speg. , Eriosyce Phil. , Blossfeldia Werderm. , Frailea Britton & Rose , Copiapoa , Eulychnia, Neowerdermannia Frič, and Austrocactus ). Nyffeler’s (2002) DNA-based study, however, showed that Notocacteae sensu Hunt et al. (2006) is highly polyphyletic and, therefore, he reduced the tribe to the strongly supported monophyletic group (“core Notocacteae ”) comprising Eriosyce s.l., Parodia Speg. s.l., and Neowerdermannia . Nyffeler & Eggli (2010) showed that the two monotypic genera Rimacactus Mottram and Yavia Kiesling & Pilz , as well as Eriosyce , Parodia , and Neowerdermannia , form a strongly supported monophyletic clade (“ Notocacteae ”). Finally, the results of Guerrero et al. (2019) corroborated the monophyly of the tribe, yet Hunt et al. (2013) upheld the inclusion of Blossfeldia Werderm. and Frailea Britton & Rose within tribe Notocacteae .
