    [GB]
    Habit
    Perennial. Rhizomes absent, or short. Culms 60-150 cm long; 3-5 -noded. Culm-nodes bearded. Leaf-sheaths mostly shorter than adjacent culm internode. Leaf-sheath oral hairs lacking, or bearded. Ligule an eciliate membrane; 1-1.3 mm long; glabrous on abaxial surface. Leaf-blades curled; flat, or involute; 10-70 cm long; 1.5-3.5 mm wide. Leaf-blade midrib widened. Leaf-blade surface glabrous, or hirsute; with tubercle-based hairs. Leaf-blade apex filiform.
    Inflorescences
    Inflorescence a panicle with branches tipped by a raceme. Panicle open; lanceolate, or oblong; 14.5-19 cm long; 2-4 cm wide. Primary panicle branches 1-6 -nate; indistinct the panicle almost racemose; 1.5-4 cm long. Panicle axis smooth, or scaberulous. Panicle branches glabrous in axils, or bearded in axils; with prominent pulvini. Racemes 1.8-5 cm long; bearing few fertile spikelets; bearing 3-6 fertile spikelets on each. Rhachis fragile at the nodes; ciliate on margins. Rhachis internodes linear; 3-6 mm long. Rhachis internode tip transverse; cupuliform. 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; 5-8 mm long; as long as fertile; separately deciduous. Companion sterile spikelet glumes membranous, or chartaceous; 5-8 -veined; pilose; muticous. Companion sterile spikelet lemmas enclosed by glumes; muticous, or 1-awned; with 0-2.5 mm long awn. Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate, or oblong; dorsally compressed; 6-8 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus brief; 0.3 mm long; pilose; base obtuse. Spikelet callus hairs white, or tawny; 1-3 mm long.
    Sterile
    Companion sterile spikelets well-developed; containing empty lemmas, or male; lanceolate; dorsally compressed; 5-8 mm long; as long as fertile; separately deciduous. Companion sterile spikelet glumes membranous, or chartaceous; 5-8 -veined; pilose; muticous. Companion sterile spikelet lemmas enclosed by glumes; muticous, or 1-awned; with 0-2.5 mm long awn.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets lanceolate, or oblong; dorsally compressed; 6-8 mm long; falling entire; deciduous with accessory branch structures. Spikelet callus brief; 0.3 mm long; pilose; base obtuse. Spikelet callus hairs white, or tawny; 1-3 mm long.
    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; 7-11 -veined. Lower glume surface pilose. Lower glume hairs tawny. Lower glume apex truncate. Upper glume ovate; coriaceous; much thinner above; without keels; 7-11 -veined. Upper glume surface pilose. Upper glume hairs tawny. Upper glume apex obtuse, or acute.
    Florets
    Basal sterile florets barren; without significant palea. Lemma of lower sterile floret lanceolate; 5.5-7 mm long; hyaline; 2 -veined; pubescent; hairy above; ciliate on margins; acute. Fertile lemma oblong; 2.5-4 mm long; hyaline; 1 -veined. Lemma surface pubescent; hairy above. Lemma margins ciliate. Lemma apex lobed; 2 -fid; awned; 1 -awned. Principal lemma awn from a sinus; geniculate; 15-20 mm long overall; with twisted column. Column of lemma awn glabrous. Palea absent or minute.
    Flowers
    Lodicules 2; oblong; fleshy; ciliate. Anthers 3; 3.5-4.5 mm long. Stigmas 2.
    Fruits
    Caryopsis with adherent pericarp; 2.5-2.8 mm long.
