    Habit
    Perennial; caespitose; clumped densely. Basal innovations intravaginal. Culms 30-50 cm long. Lateral branches lacking. Leaf-sheaths open for most of their length. Ligule an eciliate membrane, or a ciliolate membrane; 1.5-5 mm long. Leaf-blades filiform; conduplicate; 20-40 cm long; 0.8-1.2 mm wide. Leaf-blade surface scabrous; rough adaxially; glabrous.
    Inflorescences
    Inflorescence a panicle; shorter than basal leaves. Panicle contracted; linear; 10-15 cm long. Primary panicle branches appressed. Panicle axis smooth. Panicle branches smooth. Spikelets solitary. Fertile spikelets pedicelled. Pedicels smooth, or scaberulous.
    Spikelets
    Spikelets comprising 6-8 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 12-16 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1-2 mm long; pubescent.
    Fertile
    Spikelets comprising 6-8 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 12-16 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1-2 mm long; pubescent.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 7.5-9 mm long; 0.75 length of upper glume; chartaceous; without keels; 1-3 -veined. Lower glume lateral veins absent, or distinct. Lower glume surface puberulous; hairy generally, or above. Lower glume apex acuminate. Upper glume lanceolate; 9-11.5 mm long; 1.1 length of adjacent fertile lemma; chartaceous; without keels; 3-5 -veined. Upper glume surface puberulous; hairy generally, or above. Upper glume apex acuminate.
    Florets
    Fertile lemma elliptic; 8-10 mm long; chartaceous; without keel; 5 -veined. Lemma surface puberulous. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn 1-4 mm long overall. Palea 0.75 length of lemma; 2 -veined. Palea surface puberulous; hairy above. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3; 3.5 mm long. Ovary glabrous.
