    Habit
    Caespitose perennial arising from a short oblique rhizome; culms up to 60 cm tall, erect, unbranched; basal leaf sheaths firmly chartaceous to subcoriaceous, glabrous and glossy, terete, persistent; leaf laminas 2–10 cm × 0.75–1.5 mm, weakly involute-filiform, pubescent to pilose above, glabrous to pilose beneath, cartilaginous and scabrid on the margins, acute at the apex.
    Inflorescences
    Panicle 3–20 cm long, narrowly ovate, very diffuse; primary branches not in whorls, sub-dichotomously branched, the branchlets and pedicels capillary, smooth or scaberulous, eglandular, widely diverging, with a distinct pulvinus in the axils, this glabrous to thinly bearded with long white hairs, the spikelets evenly distributed.
    Spikelets
    Spikelets (0.9)1.4–1.8 mm long, dark greyish-green; inferior glume 1/3–1/2 the length of the spikelet, broadly elliptic, nerveless, glabrous, obtuse at the apex; superior glume 1/2–3/4(4/5) the length of the spikelet, ovate, nerveless, glabrous, obtuse to subacute at the apex; lemma as long as the spikelet, 1-nerved, narrowly ovate, subacute at the apex; palea 1-nerved; rhachilla not produced; anthers 3, 0.7–1 mm long.
    Fruits
    Grain 0.6–0.8 mm long, narrowly elliptic to elliptic.
