Description
Species Description - Plants 3–8 dm; lvs 1.5–6(–10) mm wide; ligules very short; spikes short and stout, 3–7(–10) cm; spikelets 7–10 mm, variously glabrous or scabrous to evidently rough-hairy; glumes and lemmas short-awned or nearly awnless; 2n=14, 28, 42. Eurasian sp., widely planted in w. U.S. as a range grass, and locally established here and there in our range. (A. pectiniforme, with subglabrous spikelets; A. sibiricum and A. desertorum, with relatively small spikelets not quite so closely crowded and not so strongly divergent from the rachis. These segregates perhaps to be recognized at some level, but the taxonomy still not clear.)
