Abstract
According to recent molecular studies (‘t Hart 1995, Ham 1995, Ham & ‘t Hart 1998, Gontcharova et al. 2006, Thiede & Eggli 2007, Gontcharova & Gontchaov 2009), the genus Phedimus Rafinesque (1817: 438) was segregated from Sedum Linnaeus (1753: 430). This taxonomic treatment of Phedimus is also supported by morphological evidences (Ohba et al. 2000, Ohba 2001, Fu et al. 2001).
