Petrophile carduacea is a species of flowering plant in the family Proteaceae and is endemic to southwestern Western Australia. It is a shrub with deeply toothed leaves, and more or less spherical heads of hairy yellow flowers.
Description
Petrophile carduacea is a shrub that typically grows to a height of 1–2 m (3 ft 3 in – 6 ft 7 in) and has hairy young branchlets. The leaves are 50–120 mm (2.0–4.7 in) long, 10–50 mm (0.39–1.97 in) wide and deeply toothed, the teeth broadly triangular and sharply-pointed. The flowers are arranged in leaf axils in more or less spherical heads about 10 mm (0.39 in) in diameter, with a few triangular involucral bracts at the base. The flowers are about 8 mm (0.31 in) long, yellow and hairy. Flowering occurs from September to October and the fruit is a nut, fused with others in an oblong head 20–35 mm (0.79–1.38 in) long on a peduncle up to 10 mm (0.39 in) long.[2][3]
Taxonomy
Petrophile carduacea was first formally described in 1856 by Carl Meissner in de Candolle's Prodromus Systematis Naturalis Regni Vegetabilis from material collected by James Drummond.[4][5] The specific epithet (carduacea) means "thistle-like".[6]
Distribution and habitat
This petrophile grows in scrub and heath in and near the Stirling Range in the Esperance Plains and Jarrah Forest biogeographic regions of southwestern Western Australia.[2][3]
Conservation status
Petrophile carduacea is classified as "Priority Two" by the Western Australian Government Department of Parks and Wildlife[3] meaning that it is poorly known and from only one or a few locations.[7]
