    Inflorescences
    Inflorescence of paired or digitate racemes; racemes with imbricate, biseriate, sessile or subsessile spikelets and terminating in an abortive spikelet.
    Spikelets
    Spikelets several-flowered, laterally compressed, disarticulating between the florets or several florets falling together, glabrous; glumes 1-nerved, unequal, keeled, coriaceous, shorter than the lemmas; lemmas 3-nerved, keeled, coriaceous, acute and muticous or mucronulate at the apex; palea with winged keels.
    Fruits

    Habit
    Perennial. Stolons present. Culms erect; 40-60 cm long. Ligule a fringe of hairs. Leaf-blades stiff. Leaf-blade apex pungent.
    Inflorescences
    Inflorescence composed of racemes. Racemes paired; unilateral. Rhachis angular; terminating in a sterile spikelet. Spikelet packing broadside to rhachis; crowded; 2 -rowed. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 5-40 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 5-20 mm long; breaking up at maturity; disarticulating below each fertile floret, or below groups of fertile florets.
    Fertile
    Spikelets comprising 5-40 fertile florets; with diminished florets at the apex. Spikelets oblong, or ovate; laterally compressed; 5-20 mm long; breaking up at maturity; disarticulating below each fertile floret, or below groups of fertile florets.
    Glume
    Glumes persistent; shorter than spikelet. Lower glume ovate; 0.75 length of upper glume; coriaceous; 1-keeled; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 0.5 length of adjacent fertile lemma; coriaceous; 1-keeled; 1 -veined. Upper glume apex acute; muticous, or mucronate. Upper glume awn subapical.
    Florets
    Fertile lemma ovate; coriaceous; 3 -veined. Lemma midvein scaberulous. Lemma lateral veins obscure. Lemma apex acute. Palea keels winged; scaberulous. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; fleshy.
    Fruits
    Caryopsis with free soft pericarp; ellipsoid; laterally compressed; trigonous. Embryo 0.3 length of caryopsis.
    Distribution
