    Habit
    Perennial; caespitose; clumped densely. Butt sheaths glossy; glabrous. Culms slender; 25 cm long. Leaf-sheaths mostly shorter than adjacent culm internode; pilose. Leaf-sheath oral hairs ciliate; 1-1.5 mm long. Ligule a fringe of hairs; 0.3-0.5 mm long. Leaf-blades filiform; involute; 3-5 cm long; 1.5 mm wide. Leaf-blade surface ribbed; hispid; hairy adaxially.
    Inflorescences
    Inflorescence a panicle. Panicle open; lanceolate, or elliptic; 5 cm long. Primary panicle branches 1 -nate. Panicle branches pilose. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 7-8 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 15-17 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.8 mm long; pubescent. Floret callus hairs 0.2-0.4 mm long.
    Fertile
    Spikelets comprising 7-8 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 15-17 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.8 mm long; pubescent. Floret callus hairs 0.2-0.4 mm long.
    Glume
    Glumes persistent; similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 15-17 mm long; 1 length of upper glume; membranous; without keels; 3-5 -veined. Lower glume lateral veins obscure. Lower glume apex acuminate. Upper glume lanceolate; 15-17 mm long; 3 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume lateral veins obscure. Upper glume apex acuminate.
    Florets
    Fertile lemma elliptic to ovate; 5-6 mm long; chartaceous; without keel; 5 -veined. Lemma apex lobed; 2 -fid; with lobes 2-3 mm long; incised 0.5 of lemma length; awned; 3 -awned. Principal lemma awn from a sinus; geniculate; flat below; 10-12 mm long overall; with twisted column. Column of lemma awn 2 mm long. Lateral lemma awns arising on apex of lobes; 4-5 mm long; shorter than principal. Palea 3 mm long; 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; cuneate; fleshy; glabrous. Anthers 3.
    Fruits
    Caryopsis with adherent pericarp. Hilum linear.
    Cleistogene
    Cleistogenes present; in lower sheaths.
