Culms 5-40 (45) cm, erect or ascending, smooth, glabrous. Sheaths 1-6 cm, uppermost sheath on each culm clearly expanded; ligules 0.2-1 mm, denticulate; blades to 7 cm long, 1.5-2.5 mm wide, adaxial surfaces scabrous. Spikes 8-25 cm, rigid, straight or somewhat curved. curved. Spikelets 5-8 mm, slightly longer than the adjacent internodes, alternate, 2-ranked. Glumes ovatelanceolate; upper glumes glabrous, midveins prominent, apices acute, sometimes mucronate; lower lemmas 4-6 mm; paleas 2-veined; anthers 2-3.5 mm. 2n = 14, 26, 52.

Distribution

S.C., Calif., Oreg., Tex., La.

Discussion
