Conostylis setosa is a rhizomatous, perennial grass-like plant or herb that has small tufts and short stems. The leaves are flat, long, wide, green with striations and glabrous apart from two ranks of hairs on the edges. The flowers are usually borne on up to four flowering stems long. The flowers are white or pinkish maroon to purple, long with lobes long. The anthers are long and the style is long. Flowering occurs from September to November.[1] [2]
Conostylis setosa was first formally described in 1840 by John Lindley in his A Sketch of the Vegetation of the Swan River Colony.[3] [4] The specific epithet (setosa) means "bristly".[5]
White cottonhead is locally common between Bindoon and Dwellingup on the Darling Scarp, in the Jarrah Forest and Swan Coastal Plain bioregions in the south-west of Western Australia.[1]
Conostylis setosa is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
