    [GB]
    Habit
    Perennial; caespitose. Culms 30-40 cm long. Culm-internodes distally glabrous. Ligule a fringe of hairs. Leaf-blades flat, or convolute; 5-20 cm long; 1-2 mm wide.
    Inflorescences
    Inflorescence a panicle. Panicle open, or contracted; lanceolate, or ovate; 8-15 cm long. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 10-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; curved; 1 mm long; pilose; pungent.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; subterete; 10-12 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus elongated; curved; 1 mm long; pilose; pungent.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 4-5(-6) mm long; 0.4 length of upper glume; membranous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex lobed; 2 -fid; obtuse; mucronate. Upper glume linear; 10-12 mm long; 2-2.5 length of adjacent fertile lemma; membranous; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex lobed; 2 -fid; mucronate.
    Florets
    Fertile lemma lanceolate; subterete; 4-6 mm long; coriaceous; without keel; 3 -veined. Lemma surface scabrous; rough above. Lemma margins convolute; covering most of palea. Lemma apex acute; awned; 3 -awned. Principal lemma awn 3-branched; with 35-50 mm long limb; with twisted column; deciduous; abscissing from top of lemma. Column of lemma awn 8-15 mm long. Lateral lemma awns 30-40 mm long; shorter than principal. Palea 0.1 length of lemma; without keels.
