Aizopsis
Introduction '''''Aizopsis''''' is a genus of the succulent family Crassulaceae (stonecrop family), found in east Asia.
Description Flowers yellow, chromosome numbers, x=16.
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 East Asia
