    Habit
    Perennial; caespitose; clumped densely. Basal innovations intravaginal. Culms erect; 20-60 cm long; 3-4 -noded; with 0.5 of their length below uppermost node; disarticulating at the nodes. Lateral branches lacking. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs ciliate; 2 mm long. Ligule a fringe of hairs. Leaf-blades erect; 20-50 cm long; 1-5 mm wide. Leaf-blade surface pubescent; hairy adaxially.
    Inflorescences
    Inflorescence a panicle; comprising 10-30 fertile spikelets. Panicle open; elliptic; 8-15 cm long; 1-3 cm wide; bearing few spikelets. Panicle branches pubescent. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 2-10 mm long; pubescent.
    Spikelets
    Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 14-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1-1.5 mm long. Floret callus evident; 1.5-2 mm long; pubescent.
    Fertile
    Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 14-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1-1.5 mm long. Floret callus evident; 1.5-2 mm long; pubescent.
    Glume
    Glumes persistent; similar; shorter than spikelet, or reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 10-18 mm long; 0.8-0.9 length of upper glume; membranous; without keels; 3-5 -veined. Lower glume apex acuminate. Upper glume lanceolate; 14-20 mm long; 2.5 length of adjacent fertile lemma; membranous; without keels; 3-5 -veined. Upper glume apex acuminate.
    Florets
    Fertile lemma ovate; 5-8 mm long; chartaceous; without keel; 9 -veined. Lemma surface pilose; hairy below. Lemma hairs 1 mm long. Lemma apex lobed; 2 -fid; incised 0.33 of lemma length; awned; 3 -awned. Principal lemma awn from a sinus; geniculate; 7.5-14 mm long overall; with twisted column. Lateral lemma awns arising on apex of lobes; 2-6 mm long; shorter than principal. Palea 5-8 mm long; 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; cuneate; 0.7-1 mm long; fleshy; glabrous. Anthers 3; 1.5-3 mm long.
    Fruits
    Caryopsis with adherent pericarp; 2.5 mm long. Embryo 0.33 length of caryopsis. Hilum elliptic.
    Cleistogene
    Cleistogenes present; in lower sheaths.
    Distribution
