    Habit
    Perennial; caespitose. Butt sheaths papery; persistent and investing base of culm. Culms 30-60 cm long; disarticulating at the nodes. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs ciliate. Ligule a fringe of hairs. Collar pubescent. Leaf-blades straight, or flexuous; deciduous at the ligule; filiform, or linear; flat, or involute; 15-25 cm long; 1-2 mm wide.
    Inflorescences
    Inflorescence a panicle; comprising 3-8 fertile spikelets. Panicle open; ovate; 3-7 cm long; bearing few spikelets. Primary panicle branches ascending; 1-2 cm long; bearing 1-2 fertile spikelets on each lower branch. Panicle branches pubescent. Spikelets solitary. Fertile spikelets pedicelled.
    Spikelets
    Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 20-27 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pilose.
    Fertile
    Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets elliptic; laterally compressed; 20-27 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; pilose.
    Glume
    Glumes persistent; similar; exceeding apex of florets; thinner than fertile lemma. Lower glume lanceolate; 20-27 mm long; 1 length of upper glume; membranous; without keels; 3-5 -veined. Lower glume lateral veins with cross-veins. Lower glume apex acute. Upper glume lanceolate; 20-27 mm long; 2 length of adjacent fertile lemma; membranous; without keels; 3-5 -veined. Upper glume lateral veins with cross-veins. Upper glume apex acute.
    Florets
    Fertile lemma elliptic; 10 mm long; chartaceous; without keel; 5 -veined. Lemma surface pilose. Lemma apex lobed; 2 -fid; incised 0.5 of lemma length; awned; 3 -awned. Principal lemma awn from a sinus; geniculate; 10-14 mm long overall; with twisted column. Lateral lemma awns arising on apex of lobes; 2 mm long; shorter than principal. Palea 2 -veined. Palea keels ciliolate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
