TaxonomyIn Berger’s system
Crassuloideae included five genera. The current classification has merged Dinacria, Pagella, Rochea, and Vauanthes into Crassula. The validity of this treatment has yet to be explicitly tested with molecular tools. Crassula sensu latu is a species rich genus with about 200 species. Crassula is a morphologically diverse genus with up to 20 sections recognised.
