    [GB]
    Habit
    Perennial; caespitose; clumped densely. Rhizomes short. Culms erect; 30-85 cm long. Leaves mostly basal. Leaf-sheaths tubular for much of their length; with 0.5-0.66 of their length closed. Ligule an eciliate membrane; 0.75 mm long. Leaf-blades conduplicate; 10-25 cm long; 1.5-2.5 mm wide. Leaf-blade surface ribbed. Leaf-blade apex obtuse.
    Inflorescences
    Inflorescence a panicle. Panicle open; ovate; effuse; 7-16 cm long; bearing few spikelets. Primary panicle branches spreading; bearing 1-3 fertile spikelets on each lower branch. Panicle branches capillary; flexuous; smooth, or scaberulous. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or elliptic; laterally compressed; 10-13 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets lanceolate, or elliptic; laterally compressed; 10-13 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; dissimilar; shorter than spikelet. Lower glume lanceolate; 3-4 mm long; 0.7-0.8 length of upper glume; hyaline; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 4-5 mm long; 0.6-0.7 length of adjacent fertile lemma; hyaline; without keels; 3 -veined. Upper glume apex acuminate.
    Florets
    Fertile lemma oblong; 6.5-8 mm long; chartaceous; much thinner on margins; purple; without keel; 5 -veined. Lemma surface smooth. Lemma apex acuminate; mucronate, or awned; 1 -awned. Principal lemma awn 0.3-1.5 mm long overall. Palea 1 length of lemma; 2 -veined. Palea keels scaberulous. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Anthers 3; 2.5-4 mm long. Ovary with a few apical hairs.
    Fruits
    Caryopsis with adherent pericarp. Hilum linear.
