    Habit
    Perennial; caespitose. Culms geniculately ascending, or decumbent; 5-40 cm long; 2-3 -noded. Leaf-sheath oral hairs ciliate. Ligule a fringe of hairs; 0.2 mm long. Leaf-blades flat, or convolute; 5-12 cm long; 1 mm wide. Leaf-blade surface pilose; sparsely hairy; hairy adaxially. Leaf-blade margins ciliate.
    Inflorescences
    Inflorescence a panicle; comprising 2-6 fertile spikelets. Panicle open; oblong; 2.5-3.5 cm long; bearing few spikelets. Panicle branches scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels scabrous.
    Spikelets
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 10-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.75-1.1 mm long; pilose. Floret callus hairs 0.5-1.2 mm long.
    Fertile
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 10-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.75-1.1 mm long; pilose. Floret callus hairs 0.5-1.2 mm long.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume linear; 10-12 mm long; 1 length of upper glume; membranous; without keels; 3 -veined. Lower glume apex acuminate. Upper glume linear; 10-12 mm long; 2.5 length of adjacent fertile lemma; membranous; without keels; 5-7 -veined. Upper glume apex acuminate.
    Florets
    Fertile lemma elliptic; 4.5 mm long; coriaceous; much thinner on margins; without keel; 5 -veined. Lemma margins ciliate. Lemma apex lobed; 2 -fid; incised 0.25 of lemma length; awned; 3 -awned. Principal lemma awn from a sinus; geniculate; 9.5-10 mm long overall; with twisted column. Column of lemma awn 2.5-3 mm long. Lateral lemma awns arising on apex of lobes; 3-4 mm long; shorter than principal. Palea 2 -veined. Palea keels 1 mm apart; ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; cuneate; fleshy; glabrous. Anthers 3; 2 mm long.
    Fruits
    Caryopsis with adherent pericarp; 1.5-2 mm long. Embryo 0.4 length of caryopsis. Hilum linear.
