Leaf-sheaths open for most of their length; glabrous on surface. Ligule a ciliolate membrane; 2-4 mm long; truncate. Leaf-blades involute, or convolute; 15-45 cm long; 2-3 mm wide; coriaceous. Leaf-blade surface smooth, or scabrous; rough adaxially, or on both sides; glabrous. Leaf-blade margins scabrous. Leaf-blade apex attenuate.
    Inflorescences
    Inflorescence a panicle. Panicle open; elliptic; 15-25 cm long. Primary panicle branches ascending; 7-15 cm long. Panicle branches scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels scabrous.
    Spikelets
    Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 8-11 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes scaberulous.
    Fertile
    Spikelets comprising 4-6 fertile florets; with diminished florets at the apex. Spikelets oblong; laterally compressed; 8-11 mm long; breaking up at maturity; disarticulating below each fertile floret. Rhachilla internodes scaberulous.

Lower glume primary vein smooth, or scaberulous. Lower glume lateral veins absent. Lower glume apex acute. Upper glume lanceolate; 5.6-7 mm long; 1 length of adjacent fertile lemma; chartaceous; without keels; 3 -veined. Upper glume primary vein smooth, or scaberulous. Upper glume apex acute.
    Florets
