Conostylis juncea 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 cylindrical or flat leaves and yellow flowers on a short flowering stem.
Description
Conostylis juncea is a rhizomatous, proliferous perennial with tufts up to 20 cm (7.9 in) in diameter. Its leaves are more or less round in cross-section or almost flat, 100–400 mm (3.9–15.7 in) long and 1–4 mm (0.039–0.157 in) wide and usually glabrous with prominent veins. The flowers borne just above the ground on a short flowering stalk with broadly egg-shaped or lance-shaped green bracts at the base. The perianth is hairy, yellow or greenish-yellow, 12–20 mm (0.47–0.79 in) long with lobes 9–12.5 mm (0.35–0.49 in) long. The anthers are 3.5–6 mm (0.14–0.24 in) long. Flowering occurs from July to September.[2][3][4]
Taxonomy and naming
Conostylis juncea was first formally described in 1839 by Stephan Endlicher in Novarum Stirpium Decades.[5][6] The specific epithet (juncea) means "rush-like".[7]
Distribution and habitat
This species of conostylis grows in sand in open woodland and heath in near-coastal areas between Jurien Bay and Australind in the Avon Wheatbelt, Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia.[2][3]
Conservation status
Conostylis juncea is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.[3]
