Abstract: 
The genus Festuca. belongs to the tribe Poeae R. Br. (=Festuceae Dumort.) and to the family of Poaceae. Because of their well adaptation to the different environmental conditions and pasturage value especially F. ovina, many botanists have frequently studied these plants. A phenetic analysis of the Iranian species of the Festuca subg. Festuca is presented here, these species concluded that F. ovina L., F. rubra L., F. heterophylla Lam., F. pinifolia (Hack.) bornm. and F. sulcata (Hack.) Beck. The plant materials studied here, in view point morphology and anatomy, were either collected from various regions in Iran, during the Years 1999-2001, or botained from several different herbaria of Iran. About 23 populations of above mentioned species were compared using a total of 21 quaulitative and quaunitative morphological characters, additionally anatomical studies were performed with 15 diagnostic characters on 15 specimens by cross section of leaves. Statistica software was utilized to perform cluster analysis. The results of cluster analysis reveal close relationship between F. sulcata and F. ovina. This confirms the opinion of Parsa in "Flore de L 'Iran" and Biossier in Flora Orientalis who had suggested the F. sulcata to be a subspecies (infraspecific relations) of F. ovina. The morphological similarities among the populations of these two secies further confirm this finding. Tow complexes species f. ovina and F. rubra present morphologic diversity in Iran and contain a lot of subspecies, varieties and cultivars. F. heterophylla are introduced as an independent species and f. pinifolia's position in the cluster analysis, separates it from all other specimens. Finally, our results ere compared and discussed with the results of others authors.
