    Habit
    Perennial; caespitose. Culms erect; 40-120 cm long. Ligule a fringe of hairs. Leaf-blades 5-20 cm long; 4-9 mm wide.
    Inflorescences
    Inflorescence a panicle; comprising 12-100 fertile spikelets. Panicle open; oblong; 5-12 cm long. Primary panicle branches simple. Panicle branches capillary; flexuous; hispid; with tubercle-based hairs. Spikelets in threes. Fertile spikelets pedicelled; 3 in the cluster; subequal. Pedicels free; filiform; subequal; 1-2 mm long.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 6-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 1 mm long; pilose; with longer hairs above; truncate.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 6-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; 1 mm long; pilose; with longer hairs above; truncate.
    Glume
    Glumes persistent; similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 4-11 mm long; 0.6-0.9 length of spikelet; chartaceous; dark brown; without keels; 3 -veined. Lower glume surface hispid; hairy on veins; with tubercle-based hairs. Lower glume apex acute. Upper glume lanceolate; 6-12 mm long; 1 length of spikelet; chartaceous; dark brown; without keels; 3 -veined. Upper glume surface hispid; hairy on veins; with tubercle-based hairs. Upper glume apex acuminate.
    Florets
    Basal sterile florets male; with palea; separately deciduous. Lemma of lower sterile floret similar to upper glume; lanceolate to oblong; 6-12 mm long; 1 length of spikelet; chartaceous; 3 -veined; acuminate. Fertile lemma oblong; 3-3.5 mm long; coriaceous; without keel; 5-7 -veined. Lemma surface pubescent; with a transverse row of hair tufts; bearing 2 hair tufts in all. Lemma margins involute; interlocking with palea keels. Lemma apex lobed; 2 -fid; awned; 3 -awned. Principal lemma awn from a sinus; geniculate; flat below; 15-30 mm long overall; with twisted column; deciduous; abscissing from top of lemma. Column of lemma awn 5-8 mm long. Lateral lemma awns arising on apex of lobes; 4-8 mm long; shorter than principal. Palea 2 -veined. Palea keels approximate; winged; narrowly winged.
    Flowers
    Anthers 3; 2-3 mm long. Ovary glabrous.
    Fruits
    Caryopsis with adherent pericarp; obovoid; 2 mm long; glabrous. Hilum linear.
