Taxonomy edit
The species in the genus Prometheum include:[1]
- Prometheum pilosum (M.Bieb.) H.Ohba
- Prometheum sempervivoides (Fisch. ex M.Bieb.) H.Ohba
- Prometheum tymphaeum (Quézel & Contandr.) 't Hart
P. sempervivoides and P. pilosum were historically included in genera Sedum (section Cyprosedum), and later Rosularia, but were elevated to a separate genus by Ohba (1995).[2]
Description edit
According to an experiment done on interspecific plant crosses in the family Crassulaceae, the genus Prometheum produced on average 55 seeds. Furthermore, the same experiment found that plants of the genus Prometheum formed a comparium with each other, meaning they were capable of interbreeding.[3]
