Densely tufted perennial, with stolons. Culms 150-200 cm tall.


Leaves distichous. Leaf-blades ascending, linear, flat or conduplicate or involute, 35-100 cm long and 4-7 mm wide, rigid, without exudate or resin. Leaf-blade margins scabrous. Leaf-sheaths inflated (1-2cm wide), 4-7 cm long, without exudate or resin, glabrous on surface. Ligule a fringe of hairs.


Inflorescence a compound panicle of racemes. Panicle open, 40-100 x 5-9 cm, contracted about thr primary branches. Primary panicle branches 9-18 cm long. Panicle axis scabrous spikelets. Spikelets solitary. Fertile spikelets many flowered, comprising of 3-4 fertile florets, with diminished florets at the apex, oblong, laterally compressed, 4-9 mm long, breaking up at maturity. Spikelets disarticulating below each fertile floret, callus glabrous, base obtuse. Glumes persistent, similar, thinner than fertile lemma. Lower glume oblong, 4-5 mm long, equalling upper glume, scarious or cartilaginous, 3-nerved, keel scabrous. Lower glume surface scabrous, rough on nerves, glabrous, apex entire, acute, muticous. Upper glume oblong, 3-4 mm long, equalling adjacent fertile lemma, scarious or cartilaginous, 1-nerved; lateral nerves absent, glabrous, apex entire, acute, muticous. Fertile lemma lanceolate, 2.8-4.5 mm long, membranous or cartilaginous or indurate, much thinner above and on margins, 3-nerved. Lemma with the lateral nerves close to margins, surface pubescent or hirsute, margins pubescent, apex dentate or lobed, 3-fid, with lobes 0.5-0.7 mm long, acute or acuminate, muticous. Palea keels narrowly winged, surface glabrous. Apical sterile florets resembling fertile though underdeveloped.
