Floristic study of Sarab-e-Kahman, Lurestan province

This study aimed to identify plant species, introducing the flora, determination of life forms, and geographical distribution of plants in Sarba kahman, from the slopes of Garin Mountains. The highs and lows of slopes and rocks have created differences of microhabitats which of them has own plant species. Plant specimens were collected from different altitude of the region, between 1800 to 3550 m. Biological spectra of the area were plotted by determining the percentage of species belonging to each of the biological forms. The position of the area within Iran’s phytogeography classification was studied based on geographical distribution data and references. According to the collection of plants from Sarab-e-Kahman area, 375 species belonging to 229 genera and 56 families were identified. The largest plant family belong to Asteraceae with 49 species. After this family, Fabaceae with 34 species, Lamiaceae with 33 species, Brassicaceae with 30 species, Liliaceae with 28 species, Poaceae with 22 species and Apiacea with 18 species, have the highest number of species in the region. Hemicryptophytes with 40% were the most frequent life form. 190 species (50 %) were endemics of Irano-Turanian region; 32 species of them were endemics of Iran.
