    Habit
    Perennial; caespitose. Rhizomes short. Basal innovations intravaginal. Culms 20-80 cm long. Leaf-sheath oral hairs bearded; 3 mm long. Ligule a fringe of hairs; 0.4-1 mm long. Leaf-blades flat, or conduplicate; 3-22 cm long; 1-2 mm wide. Leaf-blade surface glabrous, or pilose; sparsely hairy; hairy abaxially.
    Inflorescences
    Inflorescence a panicle. Panicle open; lanceolate, or ovate; 3-10 cm long. Panicle branches pubescent. Spikelets solitary. Fertile spikelets pedicelled. Pedicels pubescent.
    Spikelets
    Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 15-22 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.3 mm long. Floret callus evident; 0.5-1 mm long; pilose. Floret callus hairs 0.5-1.5 mm long.
    Fertile
    Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 15-22 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 0.3 mm long. Floret callus evident; 0.5-1 mm long; pilose. Floret callus hairs 0.5-1.5 mm long.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 15-27 mm long; 1 length of upper glume; membranous; without keels; 3-7 -veined. Lower glume apex attenuate. Upper glume lanceolate; 15-27 mm long; 1.4-1.7 length of adjacent fertile lemma; membranous; without keels; 5-7 -veined. Upper glume apex attenuate.
    Florets
    Fertile lemma elliptic; 11-13 mm long; chartaceous; without keel; 5 -veined. Lemma surface pilose; hairy below. Lemma margins ciliolate. Lemma hairs 3-4 mm long. Lemma apex lobed; 2 -fid; incised 0.66 of lemma length; awned; 3 -awned. Principal lemma awn from a sinus; curved; 10-15 mm long overall; with a straight or slightly twisted column. Lateral lemma awns arising on apex of lobes; 2-3 mm long; shorter than principal. Palea 0.5 length of lemma; 2 -veined. Palea keels 1.5-2 mm apart; ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; cuneate; fleshy; glabrous, or ciliate. Anthers 3; 1.5-2.9 mm long.
    Fruits
    Caryopsis with adherent pericarp; ovoid; 1.4-2.3 mm long. Hilum linear.
    Cleistogene
    Cleistogenes present; in lower sheaths.
