Taxonomy
In 1978, Ohba divided up the very large and cosmopolitan genus Sedum, placing Sedum aizoon and allied species into Sedum subgenus Aizoon. In 1995, he segregated these species into a separate genus, Aizopsis. However, other authors included these species in another segregate, Phedimus, as subgenus Aizoon. Subsequent molecular phylogenetic analysis established Aizopsis as a sister group to Phedimus, which with distinguishing characteristics justified their retention as a separate genus, although the distinction has not been universally adopted.

Distribution
