    [GB]
    Habit
    Perennial; caespitose. Butt sheaths sparsely hairy. Culms geniculately ascending; 35-60 cm long; 4-5 -noded. Culm-nodes glabrous. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs lacking. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 0.2 mm long; lacerate. Leaf-blades 5-19 cm long; 2-6 mm wide; glaucous. Leaf-blade surface scabrous; glabrous, or pilose; sparsely hairy; hairy adaxially. Leaf-blade margins scabrous.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; straight; bilateral; 6-8 cm long. Rhachis flattened; smooth on margins; ciliate on margins. Spikelet packing broadside to rhachis. Rhachis internodes linear. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 12-13 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.5-2 mm long; pubescent.
    Fertile
    Spikelets comprising 3 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 12-13 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.5-2 mm long; pubescent.
    Glume
    Glumes collateral; persistent; similar; shorter than spikelet. Lower glume lanceolate, or oblong; 6.5-7.5 mm long; 0.8-0.9 length of upper glume; coriaceous; much thinner on margins; without keels; 3-5 -veined. Lower glume surface asperulous. Lower glume apex acuminate; muticous, or awned; 1 -awned. Lower glume awn 0-1.5 mm long. Upper glume lanceolate, or oblong; 7.5-9 mm long; 0.9 length of adjacent fertile lemma; coriaceous; with hyaline margins; without keels; 3-5 -veined. Upper glume surface asperulous. Upper glume apex acuminate; muticous, or awned; 1 -awned. Upper glume awn 0-1.5 mm long.
    Florets
    Fertile lemma lanceolate; 8.5-10 mm long; coriaceous. Lemma surface pubescent. Lemma apex acute; awned; 1 -awned. Principal lemma awn 1.5 mm long overall. Palea lanceolate; 1 length of lemma. Palea keels ciliolate. Palea surface puberulous; hairy on back. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; membranous. Anthers 3; 2.5 mm long. Stigmas 2. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp.
