Lepismium in Allg. Gartenzeitung 3: 315. 1835 sec. Korotkova & al. (2011)
- Type: Lepismium commune
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). Recent monograph by Barthlott & Taylor (1995).
