    Habit
    Perennial; caespitose. Culms erect, or geniculately ascending; 25-50 cm long; 1 -noded. Culm-internodes smooth, or scaberulous. Leaf-sheaths open for most of their length; glabrous on surface. Ligule a ciliolate membrane; 0.5-1 mm long; truncate. Leaf-blades involute; 12-30 cm long; 1-2 mm wide; stiff. Leaf-blade surface smooth, or scaberulous; rough abaxially; pubescent; hairy adaxially. Leaf-blade margins scaberulous. Leaf-blade apex pungent.
    Inflorescences
    Inflorescence a panicle. Panicle open; linear; 8-15 cm long. Primary panicle branches appressed; bearing spikelets almost to the base. Panicle branches scabrous. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 9-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes scaberulous.
    Fertile
    Spikelets comprising 4 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 9-10 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes scaberulous.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 4-5.5 mm long; 0.8-0.9 length of upper glume; chartaceous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface asperulous; rough above. Lower glume apex acute. Upper glume lanceolate; 5-6.2 mm long; 0.8 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume surface asperulous; rough above. Upper glume apex acute.
    Florets
    Fertile lemma oblong; 6-7.2 mm long; chartaceous; without keel; 5 -veined. Lemma surface scabrous. Lemma apex dentate; 2 -fid; acute; awned; 1 -awned. Principal lemma awn from a sinus; 0.5-1 mm long overall. Palea 2 -veined. Palea keels scabrous. Palea surface pubescent; hairy above. Apical sterile florets resembling fertile though underdeveloped.
