Conostylis villosa is a rhizomatous, tufted perennial, greyish-green, grass-like plant or herb in the family Haemodoraceae and is endemic to the south west of Western Australia.

[2][3][4] Conostylis teretiuscula was first formally described in 1873 by George Bentham in his Flora Australiensis, from specimens collected by James Drummond.

[5][6] The specific epithet (villosa) means "with long, soft hairs".

[7] This species of conostylis grows in heath and scrub in scattered places between Yerecoin and Wickepin in the Avon Wheatbelt, Jarrah Forest and Mallee bioregions of south-western Western Australia.

[2][3][4] Conostylis villosa is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
