Notes

Monographs by Kiesling (1984) and Gilmer & Thomas (1998). Tephrocactus was confirmed as monophyletic by Ritz & al. (2012), and recently revised based on a phylogenetic study (Las Peñas & al. 2019). It is strongly supported within tribe Tephrocacteae (Köhler & al. 2020).A,B,C,D,E,F

Taxon standing

Category B. The genus is monophyletic based on phylogenetic studies that support the clade based on a sufficiently dense or even complete sampling, or support a monotypic genus as a distinct lineage, but do not provide a new taxonomic treatment at the species level. In many cases, older classical taxonomic synopses or a monographic treatment exist for these genera providing a reliable assessment of the species included.
