Pereskiopsis in Smithsonian Misc. Collect. 50: 331. 1907 sec. Hunt 2006
- Type: Pereskiopsis brandegeei
Phylogenetics: Pereskiopsis is monophyletic, and a member of Cylindropuntieae (Opuntieae). Quiabentia and Pereskiopsis are the only members of Opuntioideae with photosynthetically active leaves (Majure & al. 2019; Arias & al. 2012).A
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.
