    [GB]
    Habit
    Perennial; caespitose; clumped loosely. Culms 30-50 cm long; 3-4 -noded. Leaf-sheaths mostly shorter than adjacent culm internode; smooth. Ligule an eciliate membrane; 0.5 mm long; truncate. Leaf-blades flat, or involute; 7-10 cm long; 1.5-3 mm wide. Leaf-blade surface smooth, or scaberulous; glabrous.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; arcuate; bilateral; 8-10 cm long; bearing few fertile spikelets; bearing 5-8 fertile spikelets on each. Rhachis flattened; smooth on surface; glabrous on surface; smooth on margins. Spikelet packing broadside to rhachis. Rhachis internodes oblong; 14-20 mm long. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 7-9 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 22-26 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 7-9 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 22-26 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate, or oblong; 4.5-5 mm long; 0.7-0.9 length of upper glume; coriaceous; much thinner on margins; without keels; 3-5 -veined. Lower glume apex acuminate; awned; 1 -awned. Lower glume awn (1-)1.5-5(-7) mm long. Upper glume lanceolate, or oblong; 5-7 mm long; 0.5-0.6 length of adjacent fertile lemma; coriaceous; with membranous margins; without keels; 3-5 -veined. Upper glume apex acuminate; awned; 1 -awned. Upper glume awn (1-)1.5-5(-7) mm long.
    Florets
    Fertile lemma lanceolate; 11 mm long; coriaceous; 5 -veined. Lemma surface glabrous, or hispidulous. Lemma apex acute; awned; 1 -awned. Principal lemma awn curved; reflexed; 30-40 mm long overall. Palea 1 length of lemma. Palea keels ciliolate; adorned above. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; elliptic; membranous. Anthers 3; 5 mm long. Stigmas 2. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp.
