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.

Notes

Pelecyphora used to be a genus of only two species, including the well-known P. aselliformis. The generic limits of Pelecyphora were recently clarified by the phylogenetic study of Sánchez et al. (2022) who found Pelecyphora nested within Escobaria with high support based on five chloroplast regions (matK, rbcL, psbA-trnH, rpl16, and trnL-F). Escobaria and Pelecyphora were therefore merged under the older name Pelecyphora and the genus now contains 20 species and 14 subspecies.A
