    [GB]
    Habit
    Perennial; caespitose. Culms 40-70 cm long; 3-4 -noded. Culm-internodes smooth. Leaf-sheaths glabrous on surface; outer margin hairy. Leaf-sheath auricles falcate. Ligule an eciliate membrane; 0.2-0.4 mm long; truncate. Leaf-blades 10-30 cm long; 1.5-3 mm wide. Leaf-blade surface pilose; sparsely hairy; hairy adaxially. Leaf-blade margins ciliate.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; bilateral; 10-18 cm long. Rhachis flattened; scabrous on margins. Spikelet packing broadside to rhachis. Rhachis internodes linear. Rhachis internode tip flat. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 15-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2.4-2.8 mm long; pubescent.
    Fertile
    Spikelets comprising 3-5 fertile florets; with diminished florets at the apex. Spikelets lanceolate; laterally compressed; 15-20 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 2.4-2.8 mm long; pubescent.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 3.5-5 mm long; 0.5-0.6 length of upper glume; coriaceous; much thinner on margins; without keels; 3-5 -veined. Lower glume surface asperulous; rough on veins. Lower glume apex with a unilateral tooth; acute, or acuminate; muticous, or awned; 1 -awned. Lower glume awn 0-3 mm long. Upper glume lanceolate; 6-9 mm long; 0.6-0.75 length of adjacent fertile lemma; coriaceous; with hyaline margins; without keels; 3-5 -veined. Upper glume surface asperulous; rough on veins. Upper glume hairs 2 mm long. Upper glume apex with a unilateral tooth; acute, or acuminate; muticous, or awned; 1 -awned. Upper glume awn 0-3 mm long.
    Florets
    Fertile lemma oblong; 10-12 mm long; coriaceous; 5 -veined. Lemma lateral veins ribbed. Lemma surface puberulous. Lemma apex acute; awned; 1 -awned. Principal lemma awn curved; 20-40 mm long overall. Palea 1 length of lemma. Palea keels ciliolate; adorned above. Palea surface puberulous; hairy on back. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; membranous. Anthers 3; 2.8-3.2 mm long; yellow. Stigmas 2.
    Fruits
    Caryopsis with adherent pericarp.
