Conostylis prolifera, commonly known as mat cottonheads, is a rhizomatous, tufted, stoloniferous, perennial, grass-like plant or herb in the family Haemodoraceae and is endemic to the south-west of Western Australia. It has flat, glabrous leaves, and yellow and cream-coloured, tubular flowers.
Conostylis prolifera is a rhizomatous, tufted, perennial, grass-like plant or herb with small tufts, a few plants connected to each other by a network of stolons long. Its leaves are flat, glabrous, long, wide, sometimes with minute bristles on the edges. The flowers are borne in heads on a flowering stem long with a small, leaf-like bract long. The perianth is long and yellow, cream-coloured on the inside, with lobes long. The anthers are long and the style is long. Flowering occurs from August to October.[1] [2]
Conostylis prolifera was first formally described in 1873 by George Bentham in Flora Australiensis.[3] [4] The specific epithet (prolifera) means "proliferating".[5]
This conostylis grows in loam and sand in winter-wet flats between the lower Murchison River, Beverley, Tammin and Wickepin in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest, Swan Coastal Plain and Yalgoo bioregions of south-western Western Australia.[2]
Conostylis prolifera is listed as "not threatened" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions.
