Branch complement many; in a horizontal line; thinner than stem. Culm-sheaths persistent; 7-24.5 cm long; antrorsely scabrous (at base). Culm-sheath ligule 3-20 mm high; ciliolate. Culm-sheath blade triangular; cordate; indistinctly demarcated from sheath; erect; 7-17.6 cm long; scabrid. Leaves 5-9 per branch. Ligule an eciliate membrane; 10-70 mm long; truncate. Collar with external ligule. Leaf-blade base asymmetrical; with a brief petiole-like connection to sheath; petiole 0.3-0.7 cm long. Leaf-blades lanceolate; 22-40 cm long; 20-50 mm wide; stiff; yellowish green. Leaf-blade venation without cross veins. Leaf-blade surface glabrous.
    Inflorescences
    Inflorescence a panicle. Panicle contracted; linear; 28-60 cm long. Primary panicle branches appressed; 9-19 cm long. Panicle axis angular; pubescent. Panicle branches angular; glabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 2-5 mm long; glabrous.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; straight, or curved; laterally compressed; 7.1-9.6 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Fertile
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic; straight, or curved; laterally compressed; 7.1-9.6 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 0.4-0.6 mm long; membranous; without keels; 0 -veined. Lower glume lateral veins absent. Lower glume apex acute. Upper glume ovate; 0.4-0.6 mm long; 0.05 length of adjacent fertile lemma; membranous; without keels; 0 -veined. Upper glume primary vein absent. Upper glume lateral veins absent. Upper glume apex acute.
    Florets
    Basal sterile florets barren; without significant palea; attached to and deciduous with the fertile. Lemma of lower sterile floret ovate; 3.4-4 mm long; 0.4-0.5 length of fertile lemma; chartaceous; 3 -veined; acute. Lemma of upper sterile floret ovate; 3.8-5.7 mm long; chartaceous; acute. Fertile lemma ovate; 6.6-7.7 mm long; coriaceous; without keel; 5 -veined. Lemma apex apiculate. Palea 6.5-8 mm long; 4 -veined.
