The floristic diversity consisted of 205 species within 56 families. Based on number of species, Poaceae (34 Spp), Papilionaceae (19 Spp), Asteraceae (14 Spp), Chenopodiaceae (10 Spp) and Brassicaceae (9 Spp), Euphorbiaceae (8 Spp), Boraginaceae, and Polygonaceae,(each with 7 species) were the leading families. The other families had less than 7 species. Biological spectrum offlora indicated that therophytes followed by hemicryptophytes were dominant. Leaf spectra revealed that nanophylls, leptophylls, microphylls and mesophylls were the most prevalentleaf sizes. Cuscuta reflexa, Capparis decidua, Periploca aphylla, P. calophylla and Equisetum arvense were aphyllous species.enThesis
