Stoloniferous perennial without rhizomes; stolons stout, lying flat on the ground; culms robust to fairly slender, 30–60 cm. high, soft, not woody (but stolons woody).. Leaf-blades flat, mostly 5–16 cm. long, 2–6 mm. wide, thin and green or rather stiff and glaucous, scaberulous, with or without scattered hairs; ligule a scarious rim 0.3 mm. long.. Racemes in 1, or sometimes 2, whorls, slender, even flexuous, but not stiffly spreading.. Spikelets 2–3 mm. long, green or pigmented with red or purple; glumes narrowly lanceolate in side view, the upper 1/2–3/4 the length of the spikelet (or sometimes equalling the spikelet in var. robustus); lemma silky pubescent to softly ciliate on the keel; palea glabrous.
Perennial 200-600 mm high; stolons stout, woody; culm fairly slender to robust, not woody, soft. Leaf blade 50-160 x 2-6 mm; ligule a fringe of hairs. Racemes 4-16, normally slender, flexuous and spreading. Spikelet 2 to 3 mm long; rachilla produced; glumes narrowly lanceolate in side view; upper glume 1/2-3/4 as long as spikelet; lemma keel not winged, very densely silky pubescent; palea glabrous; anther 1.1-1.3 mm long.
Perennial, stoloniferous (stolons stout and woody, plants otherwise fairly soft), up to 0.6 m high. Leaf blades 50-160 mm long, 2-6 mm wide. Spikelets 2-3 mm long. Spikes usually slender, flexuous and spreading; lemma very densely, silky pubescent, keel not winged.
Spikelets 2–2.6 mm long, green or pigmented with red or purple; glumes narrowly lanceolate in profile, the superior 1/2–3/4 as long as the spikelet; lemma silky-pubescent to softly ciliate on the keel.
