Spikelets 4–6 × 1–1.5 mm, narrowly oblong, laterally compressed, 5–8-flowered, the lemmas disarticulating from below upwards, the rhachilla persistent below but fragile above; glumes subequal, 1.1–1.4 mm long, keeled, lanceolate in profile, glabrous, acute at the apex, the inferior reaching beyond the middle of the adjacent lemma, the superior to about the middle; lemmas 1.5–1.7 mm long, keeled, narrowly elliptic in profile, membranous with distinct lateral nerves, appressed to the rhachilla, those in opposite rows scarcely imbricate, the rhachilla ± visible between them, dark green to olive-green, scaberulous on the back and nerves above, obtuse at the apex; palea persistent, glabrous on the flanks, the keels slender, wingless, scaberulous; anthers 3, 0.6–1 mm long.
Perennial, stoloniferous and tufted, culms to 1 m long, geniculate to decumbent, often rooting at nodes. Leaf blades 100(-150) mm long, 2-6 mm wide. Culm nodes (without branches at nodes) with long spreading hairs. Spikelets to 7 mm long, 1.2-1.5 mm wide. Inflorescence open, branches spreading, lowest branches not whorled; spikelets linear to oblong, rhachilla persistent, sometimes becoming fragile, lemmas and paleas breaking up from base upwards; glumes half to three-quarters the length of lemmas directly above in intact spikelet; palea margins wide apart, not touching, keels a narrow line, scaberulous; anthers 3.0,8-1.0 mm long.
Perennial; stoloniferous and tufted. Culms up to 1 m long; geniculate to decumbent; often rooting at nodes; nodes barbate; without branches. Leaf blades 100(-150) x 2-6 mm. Flowers: panicle open; branches spreading; lowest branches not whorled; spikelets up to 7 x 1.2-1.5 mm; spikelets linear to oblong; rachilla persistent; sometimes becoming fragile; lemmas and paleae breaking up from base upwards; glumes 1/2-3/4 length of lemmas directly above in intact spikelet; palea margins wide apart; not touching; keels a narrow line; scaberulous; anthers 3; 0.8-1.0 mm long.
Caespitose perennial without rhizomes; culms up to 60 cm tall, usually ascending, often decumbent and rooting from the nodes, unbranched, barbate at the nodes (and pilose on the internodes), eglandular; basal leaf sheaths shortly silky-pilose below, chartaceous, terete, eglandular, persistent; ligule a line of hairs; leaf laminas 3.5–15 cm × (2)2.5–4(5) mm, linear to broadly linear, flat or rarely involute, pilose or rarely glabrous, eglandular.
Panicle 5.5–13 cm long, oblong-ovate to ovate, loose and open, the spikelets evenly distributed on pedicels 0.5–1 mm long, the primary branches not in whorls, terminating in a fertile spikelet, glabrous in the axils, eglandular.
Caryopsis 0.6–0.9 mm long, oblong to broadly elliptic.
