Description

Conostylis micrantha is a rhizomatous, perennial, grass-like plant or herb forming tufts up to 30 cm (12 in) in diameter. It has leaves that are round in cross-section, 130–240 mm (5.1–9.4 in) long, 0.7–1.2 mm (0.028–0.047 in) in diameter and glabrous, except for the lower edges of the leaves. The flowers are borne in a forked, flattened head with many flowers on a flowering stem 50–130 mm (2.0–5.1 in) tall with a hairy bract 3–8 mm (0.12–0.31 in) long at the base. The perianth is 5.0–7.5 mm (0.20–0.30 in) long, finely hairy and pale yellowish-cream aging to red, with lobes 2.5–4.5 mm (0.098–0.177 in) long, the anthers 1.0–1.7 mm (0.039–0.067 in) long and the style 3–4 mm (0.12–0.16 in) long.

Distribution and habitat

This conostylis grows heath on sandplains north of the Irwin River, in the Avon Wheatbelt and Geraldton Sandplains bioregions of south-western Western Australia.[3][4]
