The results of this survey indicate that 296 species out of 214 genera belong to 56 plant families are exist: Compositae with 47 species, Papilionaceae with 32 species, Cruciferae with 30 species, Graminae with 30 species, Labiatae with 17 species comprise the highest number of species. From viewpoint of biotypes Hemicryptophytes 44.3% Therophytes 38% Chamephytes 10.5% cryptophytes 4.4% Phanerophytes 2.8% are, from viewpoint of chorological elements Irano-Turanian elements are 51.9% Irano-Turanianm-Mediterranean Viewpoint are 14% Cosmopolitan elements are 10.5% and others species are belong to the other regions.
