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; 17-22 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 1.5 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; 17-22 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 1.5 mm long; bearded. Floret callus hairs 2-3 mm long.
    Glume
    Glumes similar; exceeding apex of florets; similar to fertile lemma in texture; gaping. Lower glume lanceolate; 18-22 mm long; 1 length of upper glume; membranous; without keels; 3 -veined. Lower glume surface asperulous. Lower glume apex acute. Upper glume lanceolate; 18-22 mm long; 2.5-2.8 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume surface asperulous. Upper glume apex acute.
    Florets
    Fertile florets female. Fertile lemma ovate; 7-8 mm long; membranous; without keel; 7 -veined. Lemma surface scaberulous; plumose; hairy below. Lemma hairs 5-6 mm long. Lemma apex lobed; 2 -fid; with filiform lobes; with lobes 0.3-1 mm long; acuminate; awned; 1 -awned. Principal lemma awn 4-8 mm long overall. Palea lanceolate; 5.5-6.3 mm long; 0.66 length of lemma; 2 -veined. Palea keels ciliolate. Palea surface glabrous, or pubescent; hairy 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.
