Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Naturalised

Rhizome short; shoots ± densely tufted. Culms erect, trigonous, smooth or scabrous above, may be shorter than inflorescence, 5–75 cm long, less than 1 mm diam.; leaf sheath front (inner face) not cross-rugulose, back (dorsal surface) of leaf sheaths occasionally septate-nodulose. Leaves exceeding or equalling culms, 1.5–3 mm wide; sheath pale to dark brown, persisting as fibrous remains; ligule obtuse to rounded. Inflorescence narrow, erect, 5–10 cm long, with 5–10 spikes solitary at nodes; lowest involucral bract shorter than inflorescence. Spikes sessile, erect to spreading at maturity, 0.5–1.5 cm long; upper spikes female or with a few male flowers above, densely contiguous; lower spikes with male flowers above female flowers, distant; glumes acute to attenuate, whitish or hyaline with green midrib; female glumes 3.0–3.5 mm long; utricles 3.5–4.5 mm long, c. 1.7 mm diam., ovoid, faintly few-nerved, glabrous, pale green to dark brown; beak c. 1 mm long, with apex split abaxially, otherwise bifid; style 2-fid. Nut obovoid to ellipsoid, lenticular, yellow-brown. Flowers spring.
