Also found in the Northern Territory, Queensland and New South Wales. Introduced to Western Australia. Native. Common in South Australia. Uncommon in the northern Territory.

Perennial sedge with long thick rhizome. Culms tufted or distant, terete or trigonous; smooth, to 60 cm high and 2.5 mm diameter. Leaves reduced to sheaths or the uppermost often with blade to 10 cm long. Inflorescence of 1-16 spikelets, spreading in a single dense, apparently lateral sessile head, a deep reddish-brown or purplish to pallid; oblong-lanceolate, turgid, to 20 mm long and 4 mm wide with 12-30-flowers, often curved or twisted. Flowers throughout the year. Fruits are flat, reddish brown fruit-head in long clusters. Seed embryo type is capitate.
Seed collection and propagation
Collect seeds between January and December. Collect fruits by picking off the mature heads, those turning a brown colour and come-off easily. Place the heads in a tray and leave to dry for one to two weeks. Then rub the heads with a rubber bung to dislodge the seeds. Use a sieve to separate any unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
