    [GB]
    Habit
    Perennial; caespitose. Culms geniculately ascending; 50-60 cm long; 2-3 -noded. Culm-internodes smooth. Culm-nodes pubescent. Leaf-sheaths 5-12 cm long; smooth. Ligule an eciliate membrane. Leaf-blades convolute; 15-20 cm long; 3 mm wide. Leaf-blade surface scaberulous; rough on both sides.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; bilateral; 8-10 cm long. Rhachis scabrous on margins. Spikelet packing broadside to rhachis. Rhachis internodes linear. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 5-6 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 12 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes scaberulous.
    Fertile
    Spikelets comprising 5-6 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 12 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes scaberulous.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 9-10 mm long; 0.9 length of upper glume; coriaceous; without keels; 3-5 -veined. Lower glume surface asperulous; rough on veins. Lower glume apex with a unilateral tooth; acute. Upper glume lanceolate; 11-12 mm long; 1.5 length of adjacent fertile lemma; coriaceous; without keels; 3-5 -veined. Upper glume surface asperulous; rough on veins. Upper glume apex with a unilateral tooth; acute.
    Florets
    Fertile lemma lanceolate; 7-8 mm long; coriaceous; 5 -veined. Lemma surface scaberulous. Lemma apex acuminate; awned; 1 -awned. Principal lemma awn 12-15 mm long overall. Palea 1 length of lemma. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; membranous. Anthers 3; 1.5 mm long. Stigmas 2. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp.
