    Perennial. Culms leaning; 50-100 cm long. Culm-internodes elliptical in section; 4-19 cm long; glandular; distally glabrous. Culm-nodes constricted; brown; glabrous, or pubescent. Lateral branches ample; arising from lower culm and upper culm. Leaf-sheaths 3-11 cm long; glandular; glabrous on surface, or hispid; outer margin hairy. Ligule a ciliate membrane; 1-1.6 mm long. Collar pubescent, or pilose. Leaf-blade base broadly rounded, or cordate. Leaf-blades lanceolate; 10-22 cm long; 10-22 mm wide; eglandular, or glandular. Leaf-blade surface glabrous, or pilose; sparsely hairy; hairy adaxially, or on both sides. Leaf-blade margins scabrous; ciliate. Leaf-blade apex attenuate.
    Inflorescences
    Inflorescence a panicle. Peduncle 9-34 cm long; glandular; glabrous, or pilose above. Panicle open; ovate; effuse; 9-21 cm long; 6-15 cm wide. Panicle axis glabrous, or pilose. Panicle branches flexuous; glandular; scaberulous; pubescent in axils. Spikelets solitary. Fertile spikelets pedicelled. Pedicels clavate; scabrous; bearing a few hairs, or ciliate.
    Spikelets
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or oblong; dorsally compressed; 2.4-3.2 mm long; 1.1-1.3 mm wide; falling entire. Rhachilla internodes elongated between glumes.
    Fertile
    Spikelets comprising 1 basal sterile florets; 1 fertile florets; without rhachilla extension. Spikelets elliptic, or oblong; dorsally compressed; 2.4-3.2 mm long; 1.1-1.3 mm wide; falling entire. Rhachilla internodes elongated between glumes.
    Glume
    Glumes similar; shorter than spikelet; thinner than fertile lemma. Lower glume ovate; clasping; 1.1-1.8 mm long; 0.5-0.75 length of spikelet; membranous; without keels; (1-)3 -veined. Lower glume apex acute. Upper glume elliptic; 2-2.4 mm long; 0.9 length of spikelet; membranous; without keels; 7-9 -veined. Upper glume lateral veins distinct. Upper glume apex acute.
    Florets
    Basal sterile florets male, or barren; with palea. Lemma of lower sterile floret similar to upper glume; elliptic; 1 length of spikelet; membranous; 7-9 -veined; acute. Palea of lower sterile floret 1 length of lemma; pilose; adorned on flanks. Fertile lemma elliptic; dorsally compressed; 1.9-2.1 mm long; indurate; yellow; without keel. Lemma surface papillose. Lemma margins involute. Lemma apex acuminate. Palea involute; indurate.
