Ligule an eciliate membrane; 0.6-1 mm long. Leaf-blades linear, or lanceolate; 1-5.5 cm long; 1.5-2 mm wide; firm; glaucous. Leaf-blade surface smooth; glabrous; hairless except near base. Leaf-blade apex acuminate.
    Inflorescences
    Inflorescence composed of racemes. Racemes 1; single; 5.5-6.5 cm long. Rhachis fragile at the nodes; semiterete; ciliate on margins. Rhachis hairs 2 mm long. Rhachis internodes filiform; 1 length of fertile spikelet. Rhachis internode tip clavate. Spikelets in pairs. Fertile spikelets sessile; 2 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels filiform; ciliate.
    Sterile
    Companion sterile spikelets rudimentary, or well-developed; containing empty lemmas, or male; lanceolate.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate; dorsally compressed; 4-6.5 mm long; falling entire; deciduous from the base and with accessory branch structures. Spikelet callus pilose; base obtuse; attached transversely. Spikelet callus hairs 2-3 mm long. Companion sterile spikelets rudimentary, or well-developed; containing empty lemmas, or male; lanceolate.

Lower glume surface with a longitudinal median groove; scabrous. Lower glume apex acuminate. Upper glume elliptic; without keels; 7 -veined. Upper glume lateral veins with cross-veins. Upper glume margins ciliolate. Upper glume apex acute; mucronate.
    Florets
    Basal sterile florets male; with palea. Lemma of lower sterile floret lanceolate; hyaline. Fertile lemma linear; 3.5-4 mm long; hyaline; without keel. Lemma margins ciliate. Lemma apex lobed; 2 -fid; incised 0.5 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 10-14 mm long overall; with twisted column. Palea absent or minute.
