Petrophile wonganensis is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is a dense shrub with blunt, needle-shaped leaves, and more or less spherical heads of hairy, yellow flowers.
Description
[edit]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.[2][3]
Taxonomy
[edit]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.[4] The specific epithet (wonganensis) refers to the type location.[5]
Distribution and habitat
[edit]This petrophile mainly occurs near Wongan Hills and towards Cowcowing, in the Avon Wheatbelt biogeographic region. It grows in heath and shrubland in sand or sandy loam.[2][3]
Conservation status
[edit]This petrophile is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[3]
