    Habit
    Perennial; caespitose; clumped loosely. Culms erect; 37-103 cm long; 2 -noded. Culm-internodes smooth; distally glabrous. Lateral branches ample. Leaf-sheath oral hairs lacking, or ciliate; 1.2-2.2 mm long. Ligule a fringe of hairs; 0.5-1 mm long. Collar glabrous, or pubescent. Leaf-blades involute; 6-12 cm long; 0.6-2 mm wide. Leaf-blade surface scabrous; rough adaxially; glabrous, or pubescent; hairy adaxially.
    Inflorescences
    Inflorescence a panicle. Panicle contracted; lanceolate; 8-27 cm long; 1.5-6 cm wide. Primary panicle branches 2-5 cm long; bearing spikelets almost to the base. Panicle branches with insignificant pulvini. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 6-14 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 0.5-1.2 mm long; pubescent; acute.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 6-14 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 0.5-1.2 mm long; pubescent; acute.
    Glume
    Glumes persistent; similar; shorter than spikelet; thinner than fertile lemma. Lower glume lanceolate; 3.7-9 mm long; 0.75 length of upper glume; membranous; 1-keeled; 1(-3) -veined. Lower glume primary vein smooth to scabrous. Lower glume lateral veins absent, or obscure. Lower glume surface smooth to scabrous. Lower glume apex acute, or acuminate. Upper glume lanceolate; 5.2-10.7 mm long; 0.7-0.8 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume surface smooth to scabrous. Upper glume apex obtuse to acuminate.
    Florets
    Fertile lemma lanceolate; subterete; 6-14 mm long; coriaceous; pallid, or light brown; concolorous, or mottled with last colour; without keel; 3 -veined. Lemma surface smooth, or scaberulous, or papillose. Lemma margins involute, or convolute; covering most of palea. Lemma apex acute; awned; 3 -awned. Principal lemma awn straight, or curved; spreading; flat below; with 8-20 mm long limb; without a column; persistent. Lateral lemma awns spreading as much as principal; 7-17 mm long; shorter than principal. Palea 0.2 length of lemma; without keels.
    Flowers
    Anthers 3; 1.3-1.9 mm long.
    Fruits
    Caryopsis with adherent pericarp; without sulcus, or sulcate on hilar side; 5-8.7 mm long. Hilum linear; 0.5 length of caryopsis.
