Description
editConostylis phathyrantha is a rhizomatous, tufted, perennial, grass-like plant or herb with short stems. Its leaves are flat, curved, 130–300 mm (5.1–11.8 in) long, 3–6 mm (0.12–0.24 in) wide and glabrous, apart from pimply leaf margins. The flowers are borne in heads on a flowering stem 60–160 mm (2.4–6.3 in) long with a linear bract 10–50 mm (0.39–1.97 in) long and several flowers, each flower on a pedicel about 5 mm (0.20 in) long. The perianth is 12–15 mm (0.47–0.59 in) long and yellow, with lobes about 5 mm (0.20 in) long, the anthers about 2 mm (0.079 in) long. Flowering occurs from August to October.[2][3][4]
Taxonomy and naming

Distribution and habitat
editThis conostylis grows in sand in heath and mallee heath between Starvation Boat Harbour and Israelite Bay in the Esperance Plains and Mallee bioregions of southern Western Australia.[2][4]
