Taxonomy
The two species, considered to comprise the genus Prometheum are Prometheum sempervivoides and Prometheum pilosum. These have historically been included in genera Sedum (section Cyprosedum), and later Rosularia, but was elevated to a separate genus by Ohba (1995).[1]
Description
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.[2]
