摘要：A forest area in Deh-Kohneh,the northwest of Fars Province,Iran was studied from a floristic and ecological point of view.The species were classified according to their growth habit.Raunkiaer’s life - forms systemwere used to characterize the flora of the study area.The location has a surface area of 466 ha by minimum altitude at 2100m and maximum at 2554m,between 30 ° 21΄ 32˝ to 30° 23΄ 00˝north longitudes and 51° 46΄ 35˝ to 51° 49΄ 41˝ east latitudes.The results showed that the flora of this region include 97 species belonging to 79 genera and 25 families.The main families in this area were Poaceae (18 species),Rosaceae (11 species) and Apiaceae (10 species).Raunkiaer’s life- forms showed that hemicryptophytes (53.6% of the species),phanerophytes (14.4%),therophytes (10.3%) and chamaephytes (8.2%) are the dominant life - forms of the area.The chorological studies indicated that all of species belong to Irano - Turanian zone,while 4% were common species in the Irano-Turanian and Hyrcanian zones.
