Notes
Several considerably different generic concepts have been suggested for Lepismium. It was either recognized as monotypic for L. cruciforme (Vell.) Miq., e.g. by Britton & Rose (1923) or included into Rhipsalis (Schumann 1899; Vaupel 1925-1926). Barthlott (1987) and Barthlott & Taylor (1995) redefined Lepismium based on the mesotonic branching as main diagnostic character, but this circumscription was found to be polyphyletic by Nyffeler (2002) and Korotkova & al. (2010). Consequently, some of its species were transferred to Lymanbensonia and Pfeiffera by Korotkova & al. (2010).A,B,C,D,E,F,G,H
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.
