    Habit
    Perennial; caespitose. Rhizomes short. Butt sheaths hirsute; persistent and investing base of culm; with fibrous dead sheaths. Culms erect; 50-100 cm long. Culm-nodes pubescent. Lateral branches lacking. Leaves mostly basal. Leaf-sheaths keeled; hirsute. Ligule an eciliate membrane; 0.7-1 mm long; truncate. Leaf-blades filiform; terete; 30-70 cm long; 1-2 mm wide. Leaf-blade surface glabrous; hairless throughout, or except near base.
    Inflorescences
    Inflorescence a panicle with branches tipped by a raceme. Panicle 4-12 cm long. Primary panicle branches 5-7 in number; 1.5-8 cm long. Rhachis fragile at the nodes; subterete; ciliate on margins. Rhachis internodes filiform. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels filiform; ciliate.
    Sterile
    Companion sterile spikelets rudimentary, or well-developed; comprising 2 subequal glumes without lemmas, or male; oblong; 2-8 mm long. Companion sterile spikelet lemmas 1-awned.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; 7-9.5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pilose; base truncate. Companion sterile spikelets rudimentary, or well-developed; comprising 2 subequal glumes without lemmas, or male; oblong; 2-8 mm long. Companion sterile spikelet lemmas 1-awned.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; dorsally compressed; 7-9.5 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus pilose; base truncate.
    Glume
    Glumes reaching apex of florets; firmer than fertile lemma. Lower glume oblong; 1 length of spikelet; chartaceous; 2-keeled; 9-11 -veined. Lower glume surface pilose. Lower glume apex truncate. Upper glume lanceolate; 1 length of spikelet; chartaceous; 1-keeled; 7 -veined. Upper glume primary vein eciliate, or ciliate. Upper glume margins ciliate. Upper glume apex acute.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; hyaline; acute. Fertile lemma oblong; hyaline; 3 -veined. Lemma margins ciliolate. Lemma apex lobed; 2 -fid; incised 0.33 of lemma length; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 10-15 mm long overall; with twisted column.
