    [GB]
    Habit
    Perennial; caespitose. Culms erect, or geniculately ascending; 70-120 cm long. Ligule an eciliate membrane. Leaf-blades 10-25 cm long; 8-12 mm wide. Leaf-blade surface scabrous; glabrous, or pilose; sparsely hairy; hairy adaxially.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; bilateral; 6-15 cm long. Rhachis flattened; scabrous on margins. Spikelet packing broadside to rhachis; crowded. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 6-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
    Fertile
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 6-15 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes pubescent.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume linear, or lanceolate; 7-10 mm long; 1 length of upper glume; coriaceous; without keels; 5-7 -veined. Lower glume lateral veins ribbed. Lower glume surface scabrous; rough on veins; inner surface pubescent (below). Lower glume apex acute; mucronate, or awned; 1 -awned. Lower glume awn 0.2-2 mm long. Upper glume lanceolate, or oblong; 7-10 mm long; 0.7-0.8 length of adjacent fertile lemma; coriaceous; without keels; 5-7 -veined. Upper glume lateral veins ribbed. Upper glume surface scabrous; rough on veins; inner surface pubescent (below). Upper glume apex acute; mucronate, or awned; 1 -awned. Upper glume awn 0.2-2 mm long.
    Florets
    Fertile lemma lanceolate; 9-12 mm long; coriaceous; keeled; keeled above; 5 -veined. Lemma surface puberulous. Lemma apex acute; awned; 1 -awned. Principal lemma awn 1-2.5 mm long overall. Palea 0.8-0.9 length of lemma. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; elliptic; membranous. Anthers 3; 2-2.5 mm long. Stigmas 2. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp.
