A loosely caespitose perennial (but frequently flowering in the first year), often of a shrubby habit. Culms up to 130 cm. tall, decumbent, rarely erect, terete, many-noded, branched, retrorsely scabrid or sometimes smooth; nodes stiffly retrorse-pilose to pubescent. Leaves evenly distributed over the culm. Leaf-sheaths coarsely striate, usually tight, sometimes slipping off the culm, retrorsely hispid to scabrid. Leaf-laminae slightly asymmetric, 3·5-12 x 1·5-2·2 (2·7) cm., lanceolate, narrowly elliptic to oblong-lanceolate, base sagittate, apex acute to acuminate, scabrid, sometimes with scattered stiff hairs along the nerves, margins often ciliate; auricles up to 12 mm. long, acute or subobtuse; pseudo-periole 0·5-2·5 mm. long. Inflorescences terminal, (3)4·5-12 cm. long, erect, straight or slightly curved, pale green; main axis flattened, 3-9 mm. wide; individual racemes up to 20 in number, 6-10 mm. long, with the rhachis c. 2·5 mm. wide. Spikelets of the axillary inflorescences up to 25 mm. long, their stigmas up to 25 mm. long or more. Male spikelets 5·5-8 mm. long, lanceolate to lanceolate-oblong in outline. Female spikelets narrowly ovate, slightly asymmetric, up to 16 mm. long, often scabrid.
