Tussocky perennial, the basal sheaths fibrous; culms 30–50 cm. high, erect.. Leaf-blades filiform, 5–30 cm. long and 0.3–0.6 mm. in diameter.. Panicle lanceolate, 6–30 cm. long, open, the spikelets on fine capillary pedicels ± 5 mm. long from relatively stout primary branches which terminate in a slender bristle.. Spikelets 2–20-flowered, elliptic to oblong, 2–9 mm. long, hoary grey, breaking up tardily if at all, the grain shed from the persistent floret scales; glumes ovate, usually subequal, 0.5–3 mm. long, glabrous or pilose; lemmas elliptic to broadly elliptic, 2–3 mm. long, densely pilose to sparsely hirsute along the margin (rarely glabrous), the nerves evanescent above the middle, obtuse to subacute (occasionally 1 or 2 of the lowest lemmas sterile with a much reduced palea); palea glabrous, the keels scaberulous; anthers 3, 1 mm. long.. Caryopsis broadly ellipsoid, 0.5–0.7 mm. long.. Fig. 63, p. 200.
Densely caespitose perennial without rhizomes or stolons; culms up to 90 cm tall, erect, unbranched, glabrous at the nodes, eglandular; basal leaf sheaths glabrous, chartaceous to firm, terete, eglandular, disintegrating into persistent fibres; ligule a line of hairs; leaf laminas 5–30 cm × 0.3–0.6 mm, filiform, glabrous, eglandular.
Panicle 6–30 cm long, lanceolate, open, the spikelets evenly distributed, the branches and branchlets stiff and straight, clearly demarcated from the slender, flexuous pedicels, these 5–10 mm long, the primary branches not in whorls, terminating in a slender bristle, glabrous in the axils, eglandular.
Caryopsis 0.5–0.7 mm long, broadly elliptic.
