Taxonomic study of Festuca L. subgenus Schedonorus (P. Beauv.) Peterm. in Iran

Abstract

This study was based upon a taxonomic review of the subgenus Schedonorus in Iran. A collection of 30 specimens belonging to the herbaria: W, B and HUI (herbarium of the University of Isfahan) were studied. Based on the results of this study, this subgenus included three species: Festuca arundinacea, F. gigantea and F. pratensis in Iran. Furthermore, this study showed that F. arundinacea, occured in this country with two subspecies: orientalis (Hack.) Tzvelev and fenas (Lag.) Arcang. with the greatest area of distribution compared to the other two species. Our examination of the type specimen of F. elatior subsp. pratensis var. elbursiana confirmed its synonymy with F. arundinacea.
