    [GB]
    Habit
    Perennial; caespitose. Rhizomes short. Culms erect; 40-90 cm long. Leaves mostly basal. Ligule an eciliate membrane; 0.5 mm long; truncate. Leaf-blades 10-40 cm long; 1-5 mm wide. Leaf-blade surface scabrous. Leaf-blade apex attenuate.
    Inflorescences
    Inflorescence composed of racemes. Racemes 6-15; borne along a central axis; unilateral; 3-9 cm long. Central inflorescence axis 4-12 cm long. Rhachis subterete. Spikelet packing broadside to rhachis; lax. Spikelets solitary. Fertile spikelets pedicelled. Pedicels linear; 0.5-1 mm long.
    Spikelets
    Spikelets comprising 2-4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 5.5-9 mm long; breaking up at maturity; disarticulating above glumes but not between florets. Floret callus evident; pilose.
    Fertile
    Spikelets comprising 2-4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 5.5-9 mm long; breaking up at maturity; disarticulating above glumes but not between florets. Floret callus evident; pilose.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 0.9-1 length of upper glume; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acuminate. Upper glume lanceolate; 1-1.2 length of adjacent fertile lemma; 1-keeled; 1 -veined. Upper glume lateral veins absent. Upper glume apex acuminate.
    Florets
