Plants forming loose hummocks and rings, spreading, 20–30 cm high, 0.6–3 m or more wide, stoloniferous. Flowering culms erect or prostrate, striate. Leaves: sheath glabrous, sometimes scaberulous; orifice glabrous; auricles to 7 mm long, fringed; blade straight, folded, 6–12.5 cm long, 1 mm wide, closely nerved on abaxial surface, with pseudopetiole scabrous adaxially. Panicles continuous or partly interrupted, 10–22 cm long, 0.5–1 cm wide. Spikelets overlapping, in 2 rows, almost sessile or with pedicel to 1 mm long, 5–10 mm long, 2–5 mm wide, loosely 3–8-flowered. Glumes ±equal or upper glume to 1.5 mm longer than lower, linear-lanceolate to elliptic, usually 1/3–2/3 as long as spikelet, entire and mucronate from apex or 2-lobed and mucronate from sinus, scabrouspubescent or partly smooth, sometimes hirsute near margins and apex. Callus bearded. Basal lemma linear-oblong, 4.3–5.5 mm long, scarious with narrow hyaline margins; body mostly hirsute; midlobe narrower than laterals or represented by a mucro. Palea ±equal to lemma body; body hirsute; keels thick, not winged. Anthers 2.5–4.3 mm long.
