Petrophile ericifolia

Petrophile ericifolia is a shrub that typically grows to a height of 0.3–1.5 m (1 ft 0 in – 4 ft 11 in) and has branchlets and leaves that are sometimes covered with curly hairs when young but that become glabrous with age. The leaves are cylindrical, up to 12 mm (0.47 in) long with a rough surface. The flowers are arranged on the ends of branchlets, in sessile, oval to spherical heads 10–20 mm (0.39–0.79 in) in diameter, with many egg-shaped, pointed involucral bracts at the base. The flowers are 10–20 mm (0.39–0.79 in) long, yellow and hairy. Flowering occurs from August to November and the fruit is a nut, fused with others in an oval head up to 20 mm (0.79 in) in diameter.

Subspecies ericifolia grows in heath and scrub from the Fitzgerald River National Park to the Stirling Range and inland to Wagin. Subspecies subpubescens grows in low shrubland mostly between Northam and Kellerberrin.
