Phylogenetics: The circumscription of Pfeiffera has undergone several radical changes in the past, and until the early 1980s, it was treated as monotypic genus with P. ianthothele (Monv.) F. A. C. Weber. Kimnach (1983) subsumed Pfeiffera under Rhipsalis, while Barthlott (1987), Barthlott & Taylor (1995) and Anderson (2001, 2005) synonymized it with Lepismium. In the molecular phylogeny of Nyffeler (2002), P. ianthothele unexpectedly grouped together with two traditional Lepismium species, and widely distant from either Rhipsalis or Lepismium. Hunt (2006) broadened the concept of Pfeiffera to include nine species. This circumscription of Pfeiffera was evaluated and clarified Korotkova & al. (2010) who rejected the circumscription of Hunt (2006) that also included the species now segregated as Lymanbensonia (see also note under Lymanbensonia). A

Taxon standing

Category A: The genus is monophyletic based on a complete or very comprehensive phylogenetic study, and a phylogeny-based taxonomic synopsis was published.B
