    Habit
    Perennial; caespitose. Basal innovations intravaginal. Culms erect, or geniculately ascending; 60-120 cm long; 3-4 -noded. Culm-nodes bearded. Lateral branches sparse. Leaf-sheaths glabrous on surface; outer margin glabrous, or hairy. Leaf-sheath oral hairs bearded. Ligule a ciliolate membrane; 0.5-1.5 mm long; pubescent on abaxial surface; truncate. Collar glabrous, or pubescent. Leaf-blades flat, or revolute; 10-25 cm long; 2-5 mm wide; glaucous. Leaf-blade venation with 7-9 secondary veins. Leaf-blade surface scaberulous; rough on both sides; pilose; sparsely hairy; hairy adaxially. Leaf-blade margins cartilaginous; scaberulous.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1-6; single, or paired, or digitate; 4-6 cm long. Central inflorescence axis 0-1.5 cm long. Rhachis fragile at the nodes; subterete; ciliate on margins. Rhachis hairs 1-1.7 mm long. Rhachis internodes filiform; 1.5-2 mm long. Raceme-bases filiform; 3-7 mm long; glabrous, or pilose. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels filiform; 1.5-2 mm long; without a translucent median line; ciliate; with 1-1.3 mm long hairs.
    Spikelets
    Basal sterile spikelets well-developed; 4 in number. Basal sterile spikelet lemmas awnless. Companion sterile spikelets well-developed; male, or bisexual; elliptic; 5.5-6.5 mm long; longer than fertile; separately deciduous. Companion sterile spikelet glumes chartaceous; 9-11 -veined; obtuse. Companion sterile spikelet lemmas enclosed by glumes; muticous, or 1-awned (when bisexual); with 0-14 mm long awn. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; obtuse; 4.5-5.5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus bearded; base obtuse; attached transversely.
    Sterile
    Basal sterile spikelets well-developed; 4 in number. Basal sterile spikelet lemmas awnless. Companion sterile spikelets well-developed; male, or bisexual; elliptic; 5.5-6.5 mm long; longer than fertile; separately deciduous. Companion sterile spikelet glumes chartaceous; 9-11 -veined; obtuse. Companion sterile spikelet lemmas enclosed by glumes; muticous, or 1-awned (when bisexual); with 0-14 mm long awn.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; obtuse; 4.5-5.5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus bearded; base obtuse; attached transversely.
    Glume
    Glumes dissimilar; exceeding apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; cartilaginous; without keels; 7-9 -veined. Lower glume primary vein scabrous. Lower glume surface concave; pubescent; hairy below; with tubercle-based hairs (on fringe); without hair tufts, or with a transverse fringe of hair. Lower glume hairs 2-3 mm long. Lower glume apex truncate. Upper glume lanceolate; 1-keeled; 3 -veined.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret 2-3 mm long; hyaline. Fertile lemma linear; hyaline; without keel; 1 -veined. Lemma apex entire; awned; 1 -awned. Principal lemma awn apical; geniculate; 15-28 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.
    Flowers
    Anthers 3; 2 mm long.
    Fruits
    Caryopsis with adherent pericarp; ellipsoid; 1.9-2.5 mm long.
