Aporocactus Lem. in Ill. Hort. 7: misc. 67. 1860 sec. Cruz & al. 2016



Used to be included in Disocactus Lindl. in recent treatments recent treatments (Barthlott 1991; Barthlott & Hunt 1993; Kimnach 1993). Cruz & al. (2016), in their phylogenetic study of Disocactus, found the two Aporocactus species to be not closely related to Disocactus but to form a separate well-supported lineage within Hylocereeae. Therefore, Aporocactus was reinstated. Two species are recognized in recent taxonomic treatments, however there are doubts about the identity of some published names. Consequently, an approximation is required in the delimitation of species.A
