Spikelets 3–7 × 1.3–1.7 mm, narrowly oblong, laterally compressed, 10–14-flowered, the lemmas disarticulating from below upwards, the rhachilla persistent below but often fragile above; glumes unequal, keeled, lanceolate in profile, glabrous, acute or subacute at the apex, the inferior 0.6–0.8 mm long, reaching to less than halfway along the adjacent lemma, the superior 1.1–1.4 mm long, reaching to just beyond the middle of the adjacent lemma; lemmas 1.3–1.5 mm long, keeled, narrowly ovate in profile, membranous with distinct lateral nerves, ± appressed to the rhachilla, those in opposite rows imbricate and concealing the rhachilla, greyish-green or purple-tinged, glabrous, subacute at the apex; palea persistent, glabrous on the flanks, the keels slender, wingless, scaberulous; anthers 3, 0.2–0.3 mm long.
Mat-forming perennial, up to 400 mm high; shortly rhizomatous; leaves mainly cauline; culms occasionally geniculate, decumbent, rooting at nodes. Leaf blade up to 100 x 4.5 mm; ligule a fringe of hairs. Inflorescence a narrow, contracted panicle; branches appressed to main axis; pedicels thick; spikelet groups often distant on main axis, spikelets appressed to branches. Spikelets 3-7 x 1.5-1.7 mm, greyish green to purple; rachilla persistent, upper part often becoming fragile, lemmas and/or paleas breaking up from base upwards; glumes shorter than spikelet, 1-nerved; upper glume acute. Florets many; lowest lemma 1.5 mm long, entire, 3-nerved, lateral veins distant, usually not reaching margins; palea keels scaberulous; anthers 3, 1.2 mm long. Flowering time July-May. Caryopsis ellipsoid to ovoid.
Mat-forming perennial, short rhizomatous and tufted (culms occasionally geniculate, decumbent and rooting at nodes), up to 400 mm tall. Leaf blades up to 100 mm long, up to 4.5 mm wide. Leaves mainly cauline. Spikelets 3-7 mm long, 1.5-1.7 mm wide. Inflorescence narrow and contracted, branches appressed to main axis, pedicels thick, spikelet groups often distant on main axis, spikelets appressed to branches; spikelets greyish green to purple, rhachilla persistent, upper part often becoming fragile, lemmas and/or paleas breaking up from base upwards; upper glume acute; lowest lemma 1.5 mm long, lateral veins distant, usually not reaching margin, never excurrent into a mucro; palea keels scaberulous; anthers 3, 1.2 mm long. Caryopsis ellipsoid to ovoid.
Perennial; up to 0.4 m high; mat-forming; shortly rhizomatous and tufted. Culms occasionally geniculate; decumbent and rooting at nodes. Leaf blades up to 100 x 4.5 mm; leaves mainly cauline. Flowers: panicle narrow and contracted; branches appressed to main axis; pedicels thick; spikelet groups often distant on main axis; spikelets appressed to branches; spikelets 3-7 x 1.5-1.7 mm; spikelets greyish green to purple; rachilla persistent; upper part often becoming fragile; lemmas and/or paleae breaking up from base upwards; upper glume acute; lowest lemma 1.5 mm long; lateral veins distant; usually not reaching margins; never excurrent into a mucro; palea keels scaberulous; anthers 3; 0.2-0.4 mm; caryopsis ellipsoid to ovoid.
Mat-forming perennial with rhizomes and often also with long stolons; culms up to 50 cm tall, erect or ascending, often decumbent and rooting at the nodes, unbranched, glabrous at the nodes, eglandular; basal leaf sheaths glabrous, chartaceous, terete (but those of non-flowering culms usually compressed), eglandular, persistent; ligule a line of hairs; leaf laminas 2.5–10 cm × 1.5–4.5 mm, linear to broadly linear, flat, glabrous, eglandular.
Mat-forming perennial, up to 400 mm tall. Leaves mainly cauline; ligule a fringe of hairs. Inflorescence a densely contracted panicle with spikelet groups often distant on thick pedicels, lowermost branches not whorled. Spikelets 3-7 x 1.5-1.7 mm, many-flowered, greyish green to purple, awnless; glumes unequal, lower lemma 1.5 mm long; anthers 0.2-0.3 mm long.
Panicle 6–15 cm long, linear, the short distant primary branches appressed to the axis, the spikelets densely contracted about them on pedicels up to 1 mm long, the primary branches not in whorls, terminating in a fertile spikelet, glabrous in the axils, eglandular.
Like E. sabulosa but spikelet groups often distant on thick pedicels, lower lemma 1.5 mm long.
Caryopsis 0.5–0.6 mm long, elliptic to ovate.
