Bagheshad is a part of Khojir national park with 2310 hectars area. It is located in 22 kilometers far from east of Tehran in south of Haraz road. It';s geographical position is 35_ 36_; 41" N to 35_ 39_; 33" and 51_ 40_; 29" and 51_ 46_; 22"E. In this study 136 species were collected and these species belong to 36 famillies (2 famillies of angiospermae, 32 famillies of dicotyledonae and 2 famillies of monocotyledonae) and 104 genera. Of the species recognized, 26 species (%19.12) are endemic species of Iran. Asteraceae with 19.12, Papilionaceae with 13.21 and Lamiaceae with 9.56 percent are the main famillies of this area. Studying of plants life forms by Raunkiaar method showed that hemycryptophytes with 50.74 percent (69 species) of species are the most frequent life forms. High percentage of hemycryptophytes indicates that the area has cold mountain climate. Therophytes whit 20.69 and chamophytes whit 15.44 percent of species, are less important. Investigation on geographical distribution of plants species showed 85.29 percent (116 species) of the species belong to Irano – Touranian zone. Other species can be observed in other zone too. High percentage of Irano – Touranian elements can express this fact that this region belongs to Irano – Touranian zone. Key words: Flora, Lifeform , Chorology, Bagheshad, Khojir national park, Iran
