A long-lived grass-like plant with long underground runners and upright flowering stems up to 40 cm tall. Its upright stems are three-angled in cross-section and only 0.5-1.5 mm thick. Its bright green leaves (1-3 mm wide) are hairless and sheath the stem at the base.

Its 'seeds' are yellow to reddish-brown in colour and topped with a small projection 1-1.5 mm long.

Impact
This widespread sedge is a common weed of habitation (i.e. gardens and lawns), disturbed sites, waste areas and wetter pastures. It has also invaded disturbed wetlands, swamps and creeks, and for this reason it is also regarded as an environmental weed in parts of Western Australia, Queensland, New South Wales and Victoria., Mullumbimby couch (Cyperus brevifolius) was recently ranked among the 200 most invasive plants in south-eastern Queensland. It also appears on environmental weed lists for the wider Sydney and Blue Mountains region and the Goulburn Broken Catchment in Victoria, and is listed as a moderately invasive species in the Environmental Weeds Strategy of Western Australia.
