    Habit
    Perennial; caespitose. Butt sheaths pilose. Culms robust; 180-300 cm long; 4-7 mm diam.; 6-7 -noded; without nodal roots. Culm-internodes brown; distally pruinose, or glabrous. Culm-nodes glabrous, or pubescent, or bearded. Ligule an eciliate membrane, or a ciliolate membrane; 2-4 mm long. Leaf-blades 8-16 mm wide. Leaf-blade surface glabrous.
    Inflorescences
    Inflorescence a panicle with branches tipped by a raceme. Panicle open; dense; 26-44 cm long; 2-4 cm wide. Primary panicle branches simple; 3-6 cm long. Racemes bearing 3-6 fertile spikelets on each. Rhachis fragile at the nodes; ciliate on margins. Rhachis internodes linear. Rhachis internode tip transverse. Spikelets in pairs. Fertile spikelets sessile; 1 in the cluster. Companion sterile spikelets pedicelled; 1 in the cluster. Pedicels filiform; flattened; ciliate.
    Spikelets
    Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; dorsally compressed; 7-9 mm long; shorter than fertile; separately deciduous. Companion sterile spikelet glumes chartaceous; 7 -veined; pubescent; ciliate on margins; muticous. Companion sterile spikelet lemmas enclosed by glumes. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 8-9 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus oblong; straight; 0.5-1.6 mm long; base obtuse.
    Sterile
    Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; dorsally compressed; 7-9 mm long; shorter than fertile; separately deciduous. Companion sterile spikelet glumes chartaceous; 7 -veined; pubescent; ciliate on margins; muticous. Companion sterile spikelet lemmas enclosed by glumes.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; dorsally compressed; 8-9 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus oblong; straight; 0.5-1.6 mm long; base obtuse.
    Glume
    Glumes dissimilar; with lower wider than upper; exceeding apex of florets; firmer than fertile lemma. Lower glume ovate; 1 length of spikelet; coriaceous; much thinner above; without keels; keel-less except near apex; 7-9 -veined. Lower glume surface glabrous to pilose. Lower glume apex acute. Upper glume ovate; coriaceous; much thinner above; without keels; 5-7 -veined. Upper glume surface pilose.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; hyaline; 2 -veined; acute. Fertile lemma oblong; hyaline; 1 -veined. Lemma apex lobed; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 25-60 mm long overall; with twisted column. Column of lemma awn ciliate. Palea absent or minute.
