    Habit
    Perennial; caespitose. Culms 50-80 cm long; 3 -noded. Culm-internodes glaucous; scaberulous; distally glabrous. Lateral branches ample. Leaf-sheaths striately veined; scaberulous; glabrous on surface. Leaf-sheath oral hairs pubescent, or ciliate. Ligule a fringe of hairs; 0.5-1 mm long. Collar pilose. Leaf-blades involute; 9-18 cm long; 2-3 mm wide. Leaf-blade surface pubescent; hairy adaxially.
    Inflorescences
    Inflorescence a panicle. Panicle contracted; elliptic; 9.5-20 cm long; 3-6 cm wide. Primary panicle branches 0.5-1.7 cm long; bearing spikelets almost to the base. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 7-13 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 0.8 mm long; pubescent; acute.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 7-13 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 0.8 mm long; pubescent; acute.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 5-11 mm long; 0.7-0.8 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume surface asperulous, or scabrous. Lower glume apex acuminate to setaceously attenuate. Upper glume lanceolate; 7-13 mm long; 1.4 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acuminate to setaceously attenuate.
    Florets
    Fertile lemma lanceolate; subterete; 5-9.5 mm long; coriaceous; without keel; 3 -veined. Lemma surface tuberculate; rough above. Lemma margins convolute; covering most of palea. Lemma apex acute; awned; 3 -awned. Principal lemma awn 3-branched; spreading; with 15-25 mm long limb; with a straight or slightly twisted column; persistent. Column of lemma awn 1-5 mm long. Lateral lemma awns spreading as much as principal; 15-25 mm long; subequal to principal. Palea 0.2 length of lemma; without keels.
    Flowers
    Anthers 3.
    Fruits
    Caryopsis with adherent pericarp; 4-6.5 mm long. Hilum linear; 0.25 length of caryopsis.
