Conostylis teretifolia is a rhizomatous, tufted, perennial, grass-like plant or herb in the family Haemodoraceae and is endemic to the south-west of Western Australia. It has flat leaves, short stems and yellow to reddish, tube-shaped flowers.
Conostylis teretifolia is a rhizomatous, tufted perennial, grass-like plant or herb that typically grows to high. The leaves are flat, long and wide and grooved with white hairs. The flowers are arranged in heads of a few flowers on a flowering stalk long, sometimes with leaf-like bracts long at the base. The perianth is long with yellow or reddish hairs, and lobes long. The anthers are long and the style long. Flowering occurs in August and September.[1] [2]
Conostylis teretifolia was first formally described in 1961 by John Green in the Proceedings of the Linnean Society of New South Wales from a specimen collected by William Blackall near Cockleshell Gully in 1938.[3] The specific epithet (teretifolia) means "terete-leaved".[4]
In 1987, Stephen Hopper described two subspecies of C. teretifolia in the Flora of Australia and the names are accepted by the Australian Plant Census:
This species of conostylis grows in sand and sandy loam. Subspecies planescens occurs in isolated sites between Gingin, Yanchep and Wanneroo in the Geraldton Sandplains, Jarrah Forest, Swan Coastal Plain bioregions of south-western Western Australia, and subsp. teretifolia in northern heaths between the Moore River and the Arrowsmith River in the Avon Wheatbelt, Geraldton Sandplains and Swan Coastal Plain bioregions.
Both subspecies of Conostylis teretifolia are listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
