Description: Tufted perennial with short rhizome. Culms rigid, erect, biconvex, or convex on 1 face and ± flat on other, glabrous, smooth, 35–60 cm high, 3.5–4.5 mm wide; margins acute, cutting, readily erose with age, yellowish.
Leaves often flatter than culms or convex on 1 face, flat on the other, shorter than culms, 2.5–4 mm wide; sheath straw-coloured at apex, otherwise very dark brown to black, occasionally viscid, very smooth and ± shining.
Inflorescence ovate to oblong in outline, erect, 5–12 cm long, 2–4 cm diam.; involucral bract shorter than inflorescence. Spikelets ± few, 6–7 mm long. Glumes 5 or 6, red-brown with blackish apex and mucro, glabrous or puberulous; lowest 3 or 4 sterile, shorter than fertile glumes, obtuse to acute, mucronate; fertile 5.5–7.0 mm long, obtuse and mucronate to long-acute. Scales 6, about a quarter the length of nut, whitish to yellowish. Anthers 2.0–2.8 mm long, excluding appendage c. 0.5 mm long.
Nut narrow-ellipsoid to narrow-ovoid, c. 2.8 mm long, 1.2–1.4 mm diam., dark grey to red-brown, smooth, shining.

NSW subdivisions: NC, CC, SC, CT, ST
Previously confused with L. laterale and L. viscidum. L. limicola has similar bases and biconvex culms but it has an oblong inflorescence with appressed clusters of spikelets, and has culm margins very scabrous, and grows in swamps.
