In this study different varieties of Bromus danthoniae in Iran are considered. Qualitative and quantitative morphological characters were evaluated for 32 accessions. Epidermal features were also studied for these accessions. The most variable morphological characters in the species delimitation were also determined. The varieties show significant variations in features as Awn status, Spike and spikelet length, Nerve number of Upper Glume, Lemma, Palea and Caryopsis length.
