Culm-sheaths persistent; 17.6-45 cm long; concolorous; antrorsely scabrous; glabrous, or hispid; hairy at the base. Culm-sheath ligule 0.2-0.5 mm high. Culm-sheath blade lanceolate; indistinctly demarcated from sheath; erect; 2.2-8 cm long; scabrid; attenuate. Ligule an eciliate membrane; 0.5-1 mm long; truncate. Collar with external ligule. Leaf-blade base with a brief petiole-like connection to sheath; petiole 0.1-0.3 cm long. Leaf-blades lanceolate; 4.4-12.2 cm long; 3-8 mm wide. Leaf-blade venation without cross veins. Leaf-blade surface glabrous, or pilose; hairy abaxially.
    Inflorescences
    Inflorescence a panicle; without bracts, or bracteate at branch bases, or bracteate at pedicel base. Panicle open; linear; 3.5-8 cm long. Primary panicle branches appressed; 1-2 cm long. Panicle axis angular; scabrous. Panicle branches angular; scabrous. Spikelets solitary. Fertile spikelets pedicelled. Pedicels angular; 1-4 mm long; scabrous.
    Spikelets
    Spikelets comprising 2 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets oblong; laterally compressed; 7.8-10 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 oblong; laterally compressed; 7.8-10 mm long; breaking up at maturity; disarticulating below each fertile floret.
    Glume
    Glumes persistent; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; 1.8-2.8 mm long; membranous; without keels; 1-3 -veined. Lower glume lateral veins absent, or distinct. Lower glume surface asperulous. Lower glume apex acute. Upper glume ovate; 4-5.1 mm long; 0.5 length of adjacent fertile lemma; membranous; without keels; 3 -veined. Upper glume surface asperulous. Upper glume apex acute; mucronate.
