Notes

The circumscription of Rhipsalis - one of the oldest genera of the family - has changed repeatedly over time, and often Hatiora, Pseudorhipsalis and Lepismium, all now accepted at generic rank, were variously subsumed under Rhipsalis. The morphology-based circumscription of Rhipsalis by Barthlott & Taylor (1995) has been entirely confirmed as monophyletic with maximal support in the molecular phylogenetic study of Korotkova & al. (2011); the same result was shown by Calvente & al. (2011), though with a less comprehensive sampling.
Rhipsalis is notable since R. baccifera (Sol.) Stearn is the only species of the family that naturally occurs outside the New World.A,B,C,D

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.
