Petrophile anceps is a species of flowering plant in the family Proteaceae and is endemic to a restricted part of southwestern Western Australia. It is a shrub with sharply-pointed, linear leaves and oval heads of hairy yellow flowers.
Description
Petrophile acicularis is a shrub that typically grows to a height of 0.5–1 m (1 ft 8 in–3 ft 3 in) and has glabrous branchlets and leaves. The leaves are linear, 60–110 mm (2.4–4.3 in) long and 2–3 mm (0.079–0.118 in) wide with a sharply-pointed tip. The flowers are arranged in sessile, oval heads about 15 mm (0.59 in) long, sometimes in clusters, with many pointed involucral bracts at the base. The flowers are about 15 mm (0.59 in) long, yellow and hairy. Flowering occurs from September to October and the fruit is a nut, fused with others in a conical head about 25 mm (0.98 in) long.[2][3]
Taxonomy
Petrophile acicularis 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 at King George's Sound.[4][5] The specific epithet (anceps) means "double", referring to the panicle.[6]
Distribution and habitat
This petrophile is restricted to the Stirling Range where it grows in heath and scrub.[2]
Conservation status
Petrophile acicularis is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[3]
