    [GB]
    Habit
    Perennial; caespitose. Butt sheaths herbaceous; glabrous, or pilose. Glands absent. Culms erect, or decumbent; 30-70 cm long; 2-5 -noded. Leaves mostly basal. Ligule a fringe of hairs. Leaf-blades filiform; 10-30 cm long; 0.5-2 mm wide. Leaf-blade surface glabrous, or pilose. Leaf-blade apex attenuate.
    Inflorescences
    Inflorescence a panicle. Panicle open; pyramidal; 10-18 cm long; 6-10 cm wide. Primary panicle branches spreading. Panicle branches capillary; eglandular. Spikelets solitary. Fertile spikelets pedicelled. Pedicels filiform.
    Spikelets
    Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets cuneate; laterally compressed; 5-9 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent.
    Fertile
    Spikelets comprising 2 fertile florets; with a barren rhachilla extension. Spikelets cuneate; laterally compressed; 5-9 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pubescent.
    Glume
    Glumes persistent; similar; exceeding apex of florets; similar to fertile lemma in texture; shiny; gaping. Lower glume elliptic; 5-9 mm long; 1 length of upper glume; membranous; yellow and purple; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume elliptic; 5-9 mm long; 2 length of adjacent fertile lemma; membranous; yellow and purple; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acuminate.
    Florets
    Fertile lemma oblong; 2.5-4.5 mm long; membranous; without keel; 5-9 -veined. Lemma surface pilose. Lemma apex lobed; 2 -fid; incised 0.2 of lemma length; awned; 3 -awned. Principal lemma awn from a sinus; geniculate; 7-15 mm long overall; with twisted column. Column of lemma awn 3-5 mm long. Lateral lemma awns arising on inner edge of lobes; 2-4 mm long; shorter than principal. Palea 1 length of lemma. Rhachilla extension 0.05 length of fertile floret.
    Flowers
    Lodicules 2; cuneate; fleshy; glabrous. Anthers 3; 2-2.5 mm long.
    Fruits
    Caryopsis with adherent pericarp.
