Leaf-sheaths 5-10 cm long; hirsute; with simple hairs, or reflexed hairs. Leaf-sheath auricles falcate; 0.5-1 mm long. Ligule an eciliate membrane; 0.1 mm long; truncate. Leaf-blades 18 cm long; 1-4 mm wide. Leaf-blade surface smooth, or scaberulous; hirsute; hairy on both sides.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; drooping; bilateral; 10-20 cm long; bearing 5-10 fertile spikelets on each. Rhachis flattened; scabrous on surface. Spikelet packing broadside to rhachis. Rhachis internodes linear. Rhachis internode tip flat. Spikelets appressed; solitary. Fertile spikelets sessile.
    Spikelets
    Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 40-55 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.5-2.3 mm long; pilose. Floret callus 0.75 mm long; pilose.
    Fertile
    Spikelets comprising 5-10 fertile florets; with diminished florets at the apex. Spikelets elliptic to oblong; laterally compressed; 40-55 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes 1.5-2.3 mm long; pilose. Floret callus 0.75 mm long; pilose.
    Glume
    Glumes persistent; similar; shorter than spikelet. Lower glume lanceolate; 4-10 mm long; 1 length of upper glume; coriaceous; 1-keeled; 3-5 -veined. Lower glume surface pilose; hairy at apex. Lower glume apex setaceously attenuate. Upper glume lanceolate; 4-10 mm long; coriaceous; 1-keeled; 3-5 -veined. Upper glume surface pilose; hairy at apex. Upper glume apex setaceously attenuate.
    Florets
    Fertile lemma lanceolate; 9-11 mm long; coriaceous; keeled; keeled above. Lemma apex awned; 1 -awned. Principal lemma awn straight; 30-50 mm long overall. Palea 9-11 mm long. Palea apex emarginate, or truncate. Apical sterile florets resembling fertile though underdeveloped.
    Flowers
    Lodicules 2; 1-1.25 mm long; membranous. Anthers 3; 1.8-2.3 mm long. Stigmas 2.
