It is a creeping, bright green, leafy, rhizomatous sedge which forms large patches of turf. The culms (10.0–80.0 by about 0.5 mm) are a bright green above, but red-brown towards the base. There are up to 6 leaves per culm, and the leaves are usually longer than the culms. The sheaths are often streaked with red, and sometimes entirely a dark red-purple. The inflorescence consists 1–2 narrow-oblong spikelets (1.0–4.0 by 0.5–2 mm) which are partly hidden by the base of the subtending bract which is up to 5 times length of spikelet. There are three stamens and three style-branches. The shining nut is 1–2 mm long by about 0.5 mm wide, triangular in cross-section with rounded angles, almost white to yellowish, or grey- to red-brown, and it tapers towards its black tip.

It flowers from October to December and fruits from November to May.
