Conostylis vaginata, commonly known as sheath conostylis, is a rhizomatous, tufted perennial, grass-like plant or herb in the family Haemodoraceae, and is endemic to the south of Western Australia. It has much-branched stems, grass-like leaves and yellow flowers arranged at the base of the leaves.
Conostylis vaginata is a rhizomatous, tufted, perennial grass-like plant or herb. Its leaves are flattened elliptical, long and wide and glabrous. The flowers are sessile and borne in pairs at the base of the leaves, each flower long with a bract long at the base. The perianth is yellow with six more or less equal tepals and six stamens, the anthers long and the style long. Flowering occurs in September or October.[1]
Conostylis vaginata was first formally described in 1846 by Stephan Endlicher in Lehmann's Plantae Preissianae.[2] [3] The specific epithet (vaginata) means "sheathed", referring to the bracts.[4]
This species of conostylis grows in sand, loam or clay on sand dunes and in winter-wet areas in the Esperance Plains, Jarrah Forest and Mallee bioregions of southern Western Australia.
Conostylis vaginata is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
