    [GB]
    Habit
    Perennial; caespitose. Culms erect, or geniculately ascending; 24-45 cm long; 2 -noded; with 0.25 of their length below uppermost node. Leaf-sheaths mostly shorter than adjacent culm internode; glabrous on surface. Ligule an eciliate membrane, or absent. Leaf-blades flat, or involute; 3-6 cm long; 1.5-3 mm wide. Leaf-blade surface scabrous; rough adaxially.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; arcuate; bilateral; 3.5-7.5 cm long. Rhachis scabrous on margins; terminating in a spikelet, or sterile spikelet. Spikelet packing broadside to rhachis; lax. Rhachis internodes 3-9 mm long. Spikelets in pairs. Fertile spikelets sessile, or pedicelled. Pedicels 1 mm long.
    Spikelets
    Basal sterile spikelets absent, or well-developed; 1-3 in number. Spikelets comprising (1-)2-3(-4) fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 9-13 mm long; breaking up at maturity; disarticulating below each fertile floret. Spikelet callus base truncate. Rhachilla internodes 1-2 mm long; pubescent. Floret callus pubescent.
    Sterile
    Basal sterile spikelets absent, or well-developed; 1-3 in number.
    Fertile
    Spikelets comprising (1-)2-3(-4) fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 9-13 mm long; breaking up at maturity; disarticulating below each fertile floret. Spikelet callus base truncate. Rhachilla internodes 1-2 mm long; pubescent. Floret callus pubescent.
    Glume
    Glumes similar; shorter than spikelet. Lower glume oblong; 2-3 mm long; 1 length of upper glume; coriaceous; without keels; 3 -veined. Lower glume primary vein scabrous. Lower glume lateral veins obscure. Lower glume apex acute, or acuminate. Upper glume oblong; 2-3 mm long; 0.25-0.33 length of adjacent fertile lemma; coriaceous; without keels; 3 -veined. Upper glume primary vein scabrous. Upper glume lateral veins obscure. Upper glume apex acute, or acuminate.
    Florets
    Fertile lemma lanceolate; 7-8 mm long; coriaceous; 5 -veined. Lemma surface puberulous; hairy above; hairy on veins. Lemma apex acute; awned; 1 -awned. Principal lemma awn 1-2 mm long overall. Palea 1 length of lemma. Palea keels ciliolate. Palea apex obtuse. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; membranous. Anthers 3; 1.7 mm long. Stigmas 2. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp. Hilum linear.
