TaxonomyEcheveria was erected by A. P. de Candolle in 1828. As of June 2018, the genus consists of about 150 species, including genera such as Oliveranthus and Urbinia that have formerly been split off from Echeveria. Molecular phylogenetic studies have repeatedly shown the genus not to be monophyletic. Species of Echeveria cluster with species of Cremnophila, Graptopetalum, Pachyphytum, and Thompsonella as well as species of Sedum section Pachysedum. The former Urbinia species do appear to form a monophyletic group within this grouping. Although it is clear that Echeveria is not monophyletic, its limits are not clear, and further analyses are needed to determine whether and how the genus should be split, or if it should be included in an expanded concept of Sedum.
