Description

Conostylis aurea is a rhizomatous, tufted perennial, grass-like herb. It grows to a height of 0.15–0.4 metres (0.49–1.31 ft) and a width of about 0.3 metres (0.98 ft).[2] As with others in the genus, the leaves are strap-like and the flowers occur in clusters on stalks which arise from the base of the leaves. There are six tepals and six stamens, one at the base of each tepal-lobe.[3] In his notes on his original description of the species, John Lindley noted "Conostylis abounds the most in species, some of which are handsome but others are mere weeds..... C. aurea is a much handsomer species....flowers of a bright golden yellow."[4]

Taxonomy and naming

The species was first formally described in 1840 by botanist John Lindley in A Sketch of the Vegetation of the Swan River Colony.[5][6] The specific epithet (aurea) is derived from the Latin word aurum meaning "gold".[7]

Distribution

The golden conostylis occurs in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain biogeographical regions of Western Australia. It grows on white or yellow sand or gravelly loam in winter-wet situations.[8]

Conservation

Conostylis aurea is classified as not threatened by the Western Australian Government Department of Parks and Wildlife.[2]

gollark: If you think I'm misleading people wouldn't that be *worse*?
gollark: That is inaccurate.
gollark: Probably. I don't aim for this, and I expect it to be more accurate than the limited public information. I could probably correct ubq if they still care.
gollark: I mean, excluding stuff like private personal details, which we don't deal with.
