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.A,B


Disocactus was newly circumscribed by Cruz & al. (2016) as the results of their phylogenetic study where Disocactus sensu Barthlott (1991) and Hunt (2006) was found as polyphyletic, with Aporocactus forming a separate lineage and Disocactus including three erstwhile Epiphyllum species.C
