Description
Flowers yellow, chromosome numbers, x=16.[2]
Taxonomy
In 1978, Ohba divided up the very large and cosmopolitan genus Sedum, placing Sedum aizoon and allied species into Sedum subgenus Aizoon.[3] In 1995, he segregated these species into a separate genus, Aizopsis.[4][5] However, other authors included these species in another segregate, Phedimus, as subgenus Aizoon.[6] Subsequent molecular phylogenetic analysis established Aizopsis as a sister group to Phedimus, which with distinguishing characteristics justified their retention as a separate genus,[2] although the distinction has not been universally adopted.[7]
Distribution
Original range from east Asia (highest diversity) and northeast Asia to central Asia (one species). Now also naturalized in Europe and North America.
