Description

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]

Classification

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]

Range

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]

gollark: What, in *number* or *pay* or what?
gollark: I don't think you can just point at that as a final answer. What is that graph even showing growth in? Why is competition not creating an incentive to get rid of useless administrators? *Is* there even much competition?
gollark: I think the point is more that it's a system which mostly works well and has produced lots of nice things.
gollark: At some point you'll have to make tradeoffs, because going for "maximize lives saved right now at all costs" is a really terrible strategy.
gollark: Strategies which minimize COVID deaths in the short run wouldn't be very good if they totally collapsed the economy after a while. Especially since this is likely to stick around for a while.
