Glumes of fertile spikelets 7-10 mm, usually velutinous, sometimes scabrous, apices with (2)3 awns, awns 2-5.5 cm; lemmas of fertile spikelets 2-awned, awns 0.5-4 cm, sometimes with 1 lateral tooth.

Discussion

Aegilops neglecta is native around the Mediterranean and in western Asia. It has been collected in Arlington County, Virginia, and near Corvallis, Oregon; the Oregon record indicates it is persisting from previous cultivation and becoming weedy.
