Cactoideae

As of August 2018, the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010. Various revisions have been published since, e.g. to the tribes Hylocereeae and Echinocereeae, and the tribe Cereeae. Classifications remained uncertain as of December 2024.
