Salzm. ex Steud.
Introduced
Treatment appears in FNA Volume 25. Treatment on page 101.

Plants perennial; cespitose, with innovations, without rhizomes, not glandular. Culms 25-75 cm, erect, glabrous below the nodes. Sheaths glabrous or with hairy apices, hairs to 4 mm; ligules 0.1-0.3 mm, ciliate; blades 4-8 (18) cm long, 1-2 mm wide, involute, frequently deciduous, adaxial surfaces mostly glabrous, sometimes pilose near the base. Panicles terminal and axillary; terminal panicles 5-15 cm long, (1) 2-10 (12) cm wide, narrowly ovate, open; axillary panicles 2-5 cm long, 0.3-0.6 cm wide, usually contracted and partially to completely enclosed by the subtending sheath; primary branches 1-10 cm, appressed or diverging up to 90° from the rachises, wiry; pulvini glabrous or hairy; pedicels 0.3-5 mm, appressed, flattened. Spikelets 6-15 (27) mm long, 1.6-2.4 mm wide, ovatelanceolate, plumbeous to greenish, often with a reddish-purple tinge, with 10-35 (45) florets; disarticulation acropetal, glumes first, then the lemmas, paleas persistent. Glumes lanceolate to ovate, membranous; lower glumes 1.4-2.1 mm; upper glumes 1.6-2.2 mm; lemmas (1.7) 2-2.5 mm, broadly ovate, leathery, apices acute to acuminate; paleas 1.1-1.7 mm, hyaline, apices obtuse to truncate; anthers 2, 0.3-0.7 mm, reddish-purple. Caryopses 0.5-0.6 mm, globose, not grooved, smooth, light reddish-brown. 2n = 40.
