The Cactoideae are the largest subfamily of the cactus family, Cactaceae. Around 80% of cactus species belong to this subfamily.[1] 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.[2] Various revisions have been published since, e.g. to the tribe Hylocereeae and the tribe Echinocereeae.[3] Classifications remained uncertain as of March 2019.
As of March 2021, the National Center for Biotechnology Information used the division of the subfamily into tribes shown below.[4] Some revisions to the circumscriptions of the tribes are also shown.
