    Habit
    Perennial; caespitose. Culms erect; 35-75 cm long. Culm-internodes smooth; distally glabrous. Lateral branches sparse. Leaf-sheaths smooth; glabrous on surface. Leaf-sheath oral hairs ciliate; 2-4.5 mm long. Ligule a fringe of hairs; 0.3 mm long. Leaf-blades involute; 10-21 cm long; 1.5 mm wide. Leaf-blade surface scabrous; rough adaxially.
    Inflorescences
    Inflorescence a panicle. Panicle open; elliptic; 7-19 cm long; 8 cm wide. Primary panicle branches 3 -nate; 1-2.4 cm long. Panicle branches glabrous. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; compressed slightly; 12-13 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.6 mm long; pubescent; acute. Floret callus hairs 1-1.5 mm long.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; compressed slightly; 12-13 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.6 mm long; pubescent; acute. Floret callus hairs 1-1.5 mm long.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 7-8 mm long; 0.6 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume primary vein scabrous. Lower glume apex acute, or acuminate. Upper glume lanceolate; 12-13 mm long; 1.5 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume primary vein scabrous. Upper glume lateral veins absent. Upper glume apex acute, or acuminate; muticous.
    Florets
    Fertile lemma lanceolate; laterally compressed; 8-9 mm long; coriaceous; without keel; 3 -veined. Lemma surface scabrous; rough above. Lemma margins convolute; covering most of palea. Lemma apex acute; awned; 3 -awned. Principal lemma awn 3-branched; spreading; with 22 mm long limb; with twisted column; deciduous; abscissing from top of lemma. Column of lemma awn 12-14 mm long. Lateral lemma awns spreading less than principal; 11 mm long; shorter than principal. Palea 0.2 length of lemma; without keels.
    Flowers
    Anthers 3.
    Fruits
    Caryopsis with adherent pericarp. Hilum linear; 0.6 length of caryopsis.
