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

Phylogenetics: The circumscription of Hatiora has been clarified recently. Hatiora including Rhipsalidopsis as adopted by Barthlott (1987), Barthlott & Hunt (1993), Barthlott & Taylor (1995), Hunt (2006) and Nyffeler & Eggli (2010) was found to be polyphyletic (Calvente & al. 2011a; Korotkova & al. 2011). Hatiora should therefore be restricted to species with cylindrical stems, terete pericarpels, and small yellow-orange or magenta flowers, corresponding to Hatiora in the traditional sense. Accordingly, Rhipsalidopsis in its traditional circumscription should again be accepted at generic rank.A
