Description
editConostylis seminuda is a rhizomatous, tufted, perennial grass-like plant or herb that typically grows to a height of 30 cm (12 in). It has flat leaves 110–210 mm (4.3–8.3 in) long, 1.5–3.5 mm (0.059–0.138 in) wide and glabrous, apart from bristles or hairs on the edges. The flowers are 10.5–12.5 mm (0.41–0.49 in) long and borne on a flowering stem up to 250 mm (9.8 in) long, the flowers golden yellow with lobes 5–8 mm (0.20–0.31 in) long. The anthers are 4.0–5.5 mm (0.16–0.22 in) long and the style is 7.5–9 mm (0.30–0.35 in) long. Flowering occurs in September and October.[2][3][4]
Taxonomy and naming
editConostylis seminuda was first formally described in 1987 by Stephen Hopper in the Flora of Australia, from specimens he collected 4 km (2.5 mi) west of the Brand Highway, east of Jurien Bay in 1982.[5] The specific epithet (seminuda) means "half-naked", referring to the sparsely-hairy leaves.[6]
Distribution and habitat
editThis conostylis grows in sand in low heath in a small area between Mount Lesueur and Alexander Morrison National Park in the Geraldton Sandplains and Swan Coastal Plain bioregions of south-western Western Australia.[2][3]
Conservation status
editConostylis seminuda is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.[2]
