Petrophile wonganensis is a species of flowering plant in the family Proteaceae and is endemic to south-western Western Australia. It is a dense shrub with blunt, needle-shaped leaves, and more or less spherical heads of hairy, yellow flowers.
Description
Petrophile wonganensis is a dense shrub that typically grows to a height of 0.5–1.5 m (1 ft 8 in – 4 ft 11 in) and has hairy young branchlets and leaves that become glabrous as they age. The leaves are blunt, needle-shaped, 5–9 mm (0.20–0.35 in) long. The flowers are arranged at the ends of branchlets in sessile, more or less spherical heads up to about 15 mm (0.59 in) in diameter, with egg-shaped or elliptic involucral bracts at the base. The flowers are about 14–15 mm (0.55–0.59 in) long, yellow and hairy. Flowering occurs from August to January and the fruit is a nut, fused with others in a more or less spherical head 15–20 mm (0.59–0.79 in) in diameter.
Taxonomy
Petrophile wonganensis was first formally described in 1995 by Donald Bruce Foreman in Flora of Australia from material collected by James Henderson Ross near Wongan Hills in 1984. The specific epithet (wonganensis) refers to the type location.
