    Habit
    Perennial; caespitose. Butt sheaths persistent and investing base of culm; with fibrous dead sheaths. Culms 30-50 cm long; 1 mm diam. Culm-nodes glabrous. Lateral branches lacking. Leaf-sheaths glabrous on surface. Leaf-sheath oral hairs bearded. Ligule a fringe of hairs; 1-1.5 mm long. Leaf-blades convolute; 10-25 cm long; 2-3 mm wide. Leaf-blade surface pilose; hairy adaxially, or on both sides. Leaf-blade margins scabrous.
    Inflorescences
    Gynodioecious (male, in this context, indicating the bisexual state). Inflorescence a panicle; exserted, or embraced at base by subtending leaf. Panicle contracted; elliptic; 4-10 cm long; 2-3 cm wide. Primary panicle branches 5 cm long. Panicle axis pilose. Panicle branches pilose. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 2-4 mm long; ciliate. Male inflorescence bisexual similar to female; a panicle. Male spikelets resembling female.
    Spikelets
    Spikelets comprising 2-3 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 14-16 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 1 mm long; bearded. Floret callus hairs 2-3 mm long.
    Fertile
    Spikelets comprising 2-3 fertile florets; with diminished florets at the apex. Spikelets cuneate; laterally compressed; 14-16 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 1 mm long; bearded. Floret callus hairs 2-3 mm long.
    Glume
    Glumes similar; shorter than spikelet; similar to fertile lemma in texture; gaping. Lower glume lanceolate; 12-15 mm long; 1 length of upper glume; membranous; without keels; 1 -veined. Lower glume lateral veins absent. Lower glume surface asperulous. Lower glume apex acute. Upper glume lanceolate; 12-15 mm long; 2 length of adjacent fertile lemma; membranous; without keels; 1 -veined. Upper glume lateral veins absent. Upper glume surface asperulous. Upper glume apex acute.
    Florets
    Fertile florets female. Fertile lemma ovate; 6-8 mm long; membranous; without keel; 7 -veined. Lemma surface plumose; hairy below. Lemma margins ciliate. Lemma hairs 5-6 mm long. Lemma apex lobed; 2 -fid; with filiform lobes; with lobes 1.2-1.8 mm long; acuminate; awned; 3 -awned. Principal lemma awn geniculate; 7-10 mm long overall; with a straight or slightly twisted column. Lateral lemma awns arising on inner edge of lobes; 1.5-2.5 mm long. Palea lanceolate; 5.5-6.5 mm long; 0.66 length of lemma; 2 -veined. Palea keels ciliolate. Palea surface pilose; hairy on back and on flanks. Palea apex dentate; 2 -fid. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; cuneate; fleshy. Anthers 3. Staminodes present; 1.5 mm long.
    Fruits
    Caryopsis with adherent pericarp.
    Male
    Male inflorescence bisexual similar to female; a panicle. Male spikelets resembling female.
    Distribution
