Description

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.

Taxonomy

Petrophile ericifolia was first formally described in 1830 by Robert Brown in the Supplementum to his Prodromus Florae Novae Hollandiae et Insulae Van Diemen from material collected by William Baxter near King Georges Sound in 1829. [4] [5] The specific epithet (ericifolia) means "erica-leaved". [6]

In 1995, Donald Bruce Foreman described two subspecies in Flora of Australia and the names are accepted by the Australian Plant Census:

Distribution and habitat

Subspecies ericifolia grows in heath and scrub from the Fitzgerald River National Park to the Stirling Range and inland to Wagin. [8] [9] Subspecies subpubescens grows in low shrubland mostly between Northam and Kellerberrin. [11] [12]

Conservation status

Both subspecies of Petrophile ericifolia are classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife. [9] [12]
