Notes

Phylogenetics: Several considerably different generic concepts have been suggested for Lepismium in the past 80 years. 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
