Leaf-sheaths tubular for much of their length; with 0.5 of their length closed; smooth. Leaf-sheath oral hairs ciliate. Leaf-sheath auricles erect; 0.3 mm long. Ligule a ciliolate membrane; 0.2 mm long. Leaf-blades filiform; conduplicate; elliptic in section; 2-15 cm long; 0.5-1.5 mm wide. Leaf-blade venation comprising 7 vascular bundles; with 3 inner ridges; with continuous uniform subepidermal sclerenchyma layer on the underside. Leaf-blade surface scabrous; rough on both sides; pubescent; hairy adaxially. Leaf-blade apex obtuse.
    Inflorescences
    Inflorescence a panicle; comprising 7-44 fertile spikelets. Panicle open; lanceolate, or oblong; 7-15 cm long. Primary panicle branches 1 -nate. Panicle axis 7-15 noded; scabrous. Panicle branches scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels 6-8.5 mm long.
    Spikelets
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets elliptic, or oblong; laterally compressed; 6-8.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 3-4 fertile florets; with diminished florets at the apex. Spikelets elliptic, or oblong; laterally compressed; 6-8.5 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
