Stoloniferous sward-forming perennial with slender underground rhizomes; stolons slender, prostrate; culms delicate, 4–15 cm. high, up to 0.4 mm. in diameter.. Leaf-blades involute, filiform, 1–4 cm. long, up to 1 mm. wide, glaucous, glabrous or with scattered hairs; ligule a short hyaline rim up to 0.3 mm. long, ciliate on the edge.. Racemes l–3(–4), 0.7–1.5 cm. long, in a single whorl.. Spikelets 2.5 mm. long; glumes subequal, lanceolate in side view, 1-nerved, the upper 1/4–1/3 as long as the spikelet; lemma lanceolate to narrowly ovate, sparsely ciliate on the keel; palea glabrous.
Perennial, 50-300 mm high; rhizomatous; culm delicate. Leaf blade delicate, very fine, involute and filiform; ligule a fringed membrane. Inflorescence digitate or subdigitate, usually 2, secund, these reflexed at maturity; rachis flattened. Spikelets 2.0-2.5 mm long, strongly laterally compressed; glumes lanceolate in side view, 1-nerved; upper glume 1/4-1/3 as long as spikelet. Floret 1, bisexual, rachilla produced, often longer than lower glume; lemma keel wingless, sparsely pubescent; palea glabrous; anther 1.4-1.7 mm long. Flowering time Nov.-May.
Perennial 50-300 mm high; rhizomatous; culm delicate. Leaf blade 1.0-1.5 mm wide, delicate, very fine, soft, involute and filiform; ligule a fringed membrane. Racemes usually 2, reflexed at maturity. Spikelet 2.0-2.5 mm long; rachilla produced and is often longer than the lower glume; glumes lanceolate in side view, 1-nerved; upper glume 1/4-1/3 as long as spikelet; lemma keel not winged, sparsely pubescent; palea glabrous; anther 1.4-1.7 mm long.
