The genus is very large, polymorphic, and cosmopolitan consisting of about 260 species (more than 370 taxa) (Tutin and Wood, 1972; Govaerts et al., 2013). Approximately 250 species in the genus are distributed around the Mediterranean basin, which is the major center of diversity (Cantino et al., 1992; Navarro and El Oualidi, 2000; Govaerts, 2013).
