Perennial, densely caespitose and erect with long filiform leaf-blades to ascending and wiry with short flat blades; culms 15–35 cm. high.. Leaf-blades filiform or flat, 2–16 cm. long and up to 3 mm. wide.. Panicle broadly ovate, 3–8 cm. long, open.. Spikelets 4–11-flowered, ovate-oblong to broadly ovate, 2–5 mm. long, dark brownish red, breaking up from the apex, the rhachilla fragile; glumes lanceolate to narrowly ovate, 1.3–2.5 mm. long, pilose, acute to acuminate; lemmas ovate-elliptic, 2–2.4 mm. long, pilose with tubercle-based hairs, obtuse to subacute and mucronate; palea glabrous on the keels, but pilose on back and flanks with stiff hairs 0.5 mm. long; anthers 3, 0.7 mm. long.. Caryopsis ellipsoid, 0.7 mm. long.
Densely caespitose perennial without rhizomes or stolons; culms up to 45 cm tall, erect or ascending, unbranched, glabrous at the nodes, eglandular; basal leaf sheaths glabrous below, chartaceous, terete, eglandular, persistent (or sometimes decaying into fibres); ligule a line of hairs; leaf laminas 2–16 cm × 1.2–3(4.5) mm, filiform or linear and flat (the latter usually the shorter), loosely pilose, eglandular.
Panicle 3–8 cm long, broadly ovate, open, the spikelets evenly distributed on filiform pedicels 2.5–9 mm long, these with a glandular ring just below the spikelet, the primary branches not in whorls, terminating in a fertile spikelet, glabrous in the axils.
Caryopsis c. 0.7 mm long, elliptic.
