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.
Taxonomy and naming
Conostylis juncea was first formally described in 1839 by Stephan Endlicher in Novarum Stirpium Decades. The specific epithet (juncea) means "rush-like".
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.
