Lathyrus L. belongs to the tribe Fabeae within the Fabaceae (Leguminosae). It contains more than 200 taxa and has an almost worldwide distribution (Allkin et al., 1986). Tutin & Heywood (1981) reported, in Flora Europaea, that 54 species are known from the area. In Flora of Turkey, Davis (1970) stated that the genus is represented by 67 taxa at the species, subspecies, and variety level. However, the number of taxa known from Turkey has since increased to 75 (Davis et al., 1988; Günes & Özhatay, 2000; Genç & Şahin, 2008; Genç, 2009). Lathyrus tefennicus H. Genç & A. Şahin, sp. nov.
