Numerical taxonomy on the Iranian species Festuca ovina L. from subgenus Festuca

The genus Festuca L. 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. In this research, different populations of the species F. ovina, in view point morphology and anatomy, were either collected from various regions in Iran, during the years 1999-2001, or obtained from several different herbaria of Iran studied here. Statistica software was utilized to perform cluster analysis on row data (17 OTU with 17 morphological characters and 17 OTU with 14 diagnostic anatomical characters). The results of cluster analyses reveal close relationship between F. sulcata and F. ovina. This confirms the opinion of Parsa in Flore de L Iran and Boissier 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 species further confirm this finding and the species of F. ovina must be as an aggregate species with subspecies taxa in Iran. Finally, our results were compared and discussed with the results of others authors.
