Native warm-season perennial erect sedge 1-2 m tall and with long creeping rhizomes and woody tubers. Stems are 5-10 mm diameter and 3-sided. Leaves are to 12mm wide. Flowerheads have 6-9 branches, each with 1-6 brown spikelets to 2.5cm long. Flowers from spring to summer. Widespread in shallow water of creek edges and open swamps. Will grow out of water in higher rainfall areas. Palatable when young and leafy, but not when mature. Provides relatively low-digestibility feed, but can have high protein levels. Appears to be susceptible to continuous grazing and trampling. Often forms dense stands outside grazed paddocks, which are used as shelter by many native waterbirds, mammals, etc. Generally will not spread into deeper water. Don’t graze below the waterline in autumn.
