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.
Phylogenetics: Griffith & Porter (2009) found no support for a monophyletic Cylindropuntia based on combined nuclear and plastid markers, while Bárcenas & al. (2011, 2015) found a monophyletic Cylindropuntia with high to maximal support based on plastid data only. Majure et al. (2019) showed that Cylindropuntia was indeed monophyletic and sister to Grusonia s.l., and Micropuntia was sister to the Grusonia + Cylindropuntia clade. See also under Grusonia and Micropuntia.A
