Taxonomy

Petrosedum is a genus in the family Crassulaceae, subfamily Sempervivoideae, tribe Semperviveae, together with two other genera. It was segregated from the very large cosmopolitan and polyphyletic genus Sedum , where it was variously considered a series (Rupestria). It was originally described with eleven species. ^[1]
