Resumen

The present study was carried out in the Hashtadpahlou and Sefidkoh mountains which are important vegetation regions in the western Iran, Lorestan. The endemic plants and their life form in these mountain regions were determined. From the view point of regional elements, plants of these regions belong to Irano-Turanian region. Totally, 86 endemic plants from 18 families were recognized. The results show that the important families are Asteraceae (20 species), Fabaceae (14 species), Lamiaceae (13 species). The highest number of species investigated for Astragalus genus (11 species). Life forms of the plant species of region include: geophytes 26.44%, therophytes 16.09%, hemicryptophytes 18.38%, chamaephytes 31.04%, phanerophytes 8.08% .The high frequency of chamaephytes and geophytes can be attributed to high altitude and cold climate. Generally, it can be declared that the habitats of these ecosystems have high diversity due to the presence of 87 endemic plants and this pattern resulted from climate conditions and geomorphology of territory.
