Culms 20-55 cm, geniculate and semiprostrate at the base, usually with many tillers. Sheaths with hyaline margins, ciliate; blades 5-8 cm long, 3-4 mm wide. Spikes 2-4.5 cm long, 0.4-1.3 cm wide, ovoid-ellipsoid proximally, abruptly contracted distally to a narrow cylinder, with 3-6 spikelets, the distal 1-3 spikelets sterile; rudimentary spikelets (2)3; disarticulation at the base of the spikes. Fertile spikelets 8-12 mm, subventricose, urceolate, with 2 fertile florets and 2-3 sterile florets; apical spikelets 4-5 mm, usually with 1 sterile floret, cultivated forms often with 1 fertile floret and 1-2 sterile florets. 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. Caryopses 5-7 mm, falling free of the lemmas and paleas. Haplomes UM, UMN. 2n = 28, 48.
