Description edit

The monoecious and rhizomatous perennial sedge has a dense tufted habit. It typically grows to a height of 0.4 to 1 metre (1.3 to 3.3 ft). The plant blooms between October and December producing purple flowers.[1] The culms are unitubulose and around 0.5 to 1 metre (1.6 to 3.3 ft) in length with a diameter of 1.5 to 4 millimetres (0.059 to 0.157 in). They become yellow-green at maturity and are longitudinally striate. The inner leaf blades grow to about 25 centimetres (9.843 in) long and are yellow-brown to red-brown in colour. The narrow-ovoid to ovoid inflorescence is 11 to 15 mm (0.43 to 0.59 in) in length with a width of 5 to 10 mm (0.20 to 0.39 in) containing may pseudospikelets.[3]
