TaxonomyIn 1978, Ohba divided up the very large and cosmopolitan genus Sedum, placing Sedum aizoon and allied species into Sedum subgenus Aizoon. Later he segregated these species into the separate genus Aizopsis. Other authors included these species in another segregate, Phedimus, subgenus Aizoon. Molecular phylogenetic analysis established Aizopsis as a sister group to Phedimus, which with distinguishing characteristics justified their retention as a separate genus.
