Leaf-sheaths mostly shorter than adjacent culm internode; glabrous on surface. Leaf-sheath oral hairs pubescent. Ligule a fringe of hairs. Leaf-blades convolute; 8-10 cm long; 2 mm wide. Leaf-blade surface scaberulous; rough adaxially. Leaf-blade apex acuminate; filiform.
    Inflorescences
    Inflorescence a panicle. Panicle open; elliptic; 15 cm long; contracted about primary branches. Primary panicle branches 1-2 -nate. Panicle axis scaberulous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 2-5 mm long; scaberulous.
    Spikelets
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear; subterete; 7-9 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.5-0.75 mm long; pubescent; acute.
    Fertile
    Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets linear; subterete; 7-9 mm long; breaking up at maturity; disarticulating below each fertile floret. Floret callus evident; 0.5-0.75 mm long; pubescent; acute.
    Glume
    Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 7-9 mm long; 1.2-1.3 length of upper glume; membranous; 1 -veined. Lower glume primary vein scabrous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 6-7 mm long; membranous; 1 -veined. Upper glume primary vein smooth. Upper glume lateral veins absent. Upper glume apex acute.
    Florets
    Fertile lemma linear; subterete; 6-8 mm long; coriaceous; without keel; 3 -veined. Lemma midvein scabrous. Lemma surface scabrous; rough above. Lemma margins convolute; covering most of palea. Lemma apex awned; 3 -awned. Principal lemma awn with 20 mm long limb. Lateral lemma awns 10-15 mm long; shorter than principal.
