Chorizandra cymbaria, commonly known as heron bristle rush[1] or heron bristle sedge,[2] is a sedge of the family Cyperaceae that is native to Australia.
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 ovoidinflorescence 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]
The plant was first formally described by the botanist Robert Brown in 1810 as part of the work Prodromus Florae Novae Hollandiae. The name is often misapplies to Chorizandra australis.[4]
The species is found in damp areas in Western Australia, Victoria,[2] Tasmania, coastal areas of New South Wales and Queensland.[3] In Western Australia it is found in peaty swamp areas along the coast of the South West and Great Southern regions where it grows in sandy-clay soils.[1]
