    Perennial; caespitose. Culms geniculately ascending; 15-70 cm long. Leaf-sheaths open for most of their length; glabrous on surface. Ligule an eciliate membrane; 2-3 mm long; acute. Leaf-blades conduplicate; 0.5-1 mm wide. Leaf-blade margins scabrous. Leaf-blade apex acute.
    Inflorescences
    Inflorescence a panicle; embraced at base by subtending leaf. Panicle open; linear; 10-30 cm long. Primary panicle branches appressed. Panicle axis scabrous. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 5-12 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed slightly; 5-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1 mm long; smooth.
    Fertile
    Spikelets comprising 5-12 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; compressed slightly; 5-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1 mm long; smooth.
    Glume
    Glumes persistent; shorter than spikelet. Lower glume elliptic; 1.5-2 mm long; 0.75 length of upper glume; membranous; much thinner on margins; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume elliptic; 2-2.8 mm long; 0.75-0.9 length of adjacent fertile lemma; membranous; with hyaline margins; without keels; 3 -veined. Upper glume apex acute.
    Florets
    Fertile lemma oblong; 2.8-3 mm long; membranous; much thinner above; without keel; 5 -veined. Lemma lateral veins obscure; stopping well short of apex. Lemma surface pubescent; hairy below; hairy on back, or on veins. Lemma apex obtuse, or acute. Palea 1 length of lemma; 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3; 0.5 mm long. Ovary glabrous.
    Fruits
    Caryopsis with adherent pericarp; ellipsoid; 1.8-2 mm long. Hilum punctiform.
