Leaf-sheaths loose; glabrous on surface. Ligule an eciliate membrane; 1 mm long; truncate. Leaf-blades 11-25 cm long; 3-5-7 mm wide. Leaf-blade surface hirsute; hairy adaxially, or on both sides.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; drooping; bilateral; 8-9 cm long; bearing 6-8 fertile spikelets on each. Rhachis flattened; puberulous on surface; ciliate on margins. Spikelet packing broadside to rhachis; regular; 2 -rowed. Rhachis internodes 7-14 mm long. Spikelets solitary. Fertile spikelets sessile.
    Spikelets
    Basal sterile spikelets well-developed; 3-4 in number. Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets laterally compressed; 24-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 3 mm long; pilose. Floret callus pubescent.
    Sterile
    Basal sterile spikelets well-developed; 3-4 in number.
    Fertile
    Spikelets comprising 5-7 fertile florets; with diminished florets at the apex. Spikelets laterally compressed; 24-30 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 3 mm long; pilose. Floret callus pubescent.
    Glume
    Glumes persistent; similar; subequal in width; shorter than spikelet. Lower glume lanceolate; 5-7.5 mm long; coriaceous; without keels; 3-7 -veined. Lower glume surface scabrous; rough on veins. Lower glume apex acute; muticous. Upper glume oblong; 7-9 mm long; coriaceous; without keels; 3-7 -veined. Upper glume surface scabrous; rough on veins. Upper glume apex acute; muticous.
    Florets
    Fertile lemma lanceolate; 13-14 mm long; coriaceous; without keel; 5 -veined. Lemma surface hirsute. Lemma hairs 1-1.5 mm long. Lemma apex awned; 1 -awned. Principal lemma awn reflexed; 20-35 mm long overall. Palea 0.9-1 length of lemma; 2 -veined. Palea surface puberulous; hairy on back; hairy above. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; membranous. Anthers 3; 2 mm long; brown. Stigmas 2. Ovary pubescent on apex.
    Fruits
    Caryopsis with adherent pericarp; hairy at apex; apex unappendaged. Hilum linear.
