    [GB]
    Habit
    Perennial; caespitose. Culms erect; 20-80 cm long; disarticulating at the nodes. Culm-nodes glabrous. Lateral branches lacking. Leaves mostly basal. Leaf-sheaths glabrous on surface, or puberulous; with simple hairs, or tubercle-based hairs. Leaf-sheath oral hairs ciliate. Ligule a fringe of hairs. Leaf-blades curled, or flexuous; filiform; flat, or involute; 7-15 cm long; 1-2 mm wide.
    Inflorescences
    Inflorescence a panicle. Panicle contracted; linear; 2-5 cm long; bearing few spikelets. Primary panicle branches indistinct the panicle almost racemose; bearing 1 fertile spikelets on each lower branch. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 1-3 mm long.
    Spikelets
    Spikelets comprising 4-9 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 10-13 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent.
    Fertile
    Spikelets comprising 4-9 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 10-13 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 10-13 mm long; 1 length of upper glume; membranous; without keels; 3-5 -veined. Lower glume apex acuminate. Upper glume lanceolate; 10-13 mm long; 2.6-2.8 length of adjacent fertile lemma; membranous; without keels; 3-5 -veined. Upper glume apex acuminate.
    Florets
    Fertile lemma elliptic; 3.5-5 mm long; chartaceous; without keel; 5 -veined. Lemma surface pubescent. Lemma margins ciliolate. Lemma apex lobed; 2 -fid; incised 0.25 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 5-7 mm long overall. Palea 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; cuneate; fleshy; glabrous. Anthers 3.
    Fruits
    Caryopsis with adherent pericarp. Hilum linear.
    Cleistogene
