Petrophile pauciflora
Petrophile pauciflora is a species of flowering plant in the family Proteaceae and is endemic to western areas of Western Australia. It is a shrub usually with three-forked leaves, the lobes sharply-pointed, and spherical heads of small groups of hairy yellow or orange flowers. DescriptionPetrophile pauciflora is a shrub that typically grows to a height of 0.5–1 m (1 ft 8 in – 3 ft 3 in) and has hairy young branchlets and leaves that become glabrous as they age. The leaves are 15–35 mm (0.59–1.38 in) long and cylindrical but three-forked, the middle segment sometimes divided again, each segment sharply-pointed. The flowers are arranged near the ends of branchlets in spherical heads about 8 mm (0.31 in) in diameter, with egg-shaped involucral bracts at the base. The heads contain only a few flowers, each about 7 mm (0.28 in) long, yellow or orange, and hairy. Flowering has been observed in September and the fruit is a nut, fused with others in an oval or spherical head 6–8 mm (0.24–0.31 in) long.[2][3] TaxonomyPetrophile pauciflora was first formally described in 1995 by Donald Bruce Foreman in Flora of Australia from material collected by Alex George near Bimbijy Station in 1976.[4] The specific epithet (pauciflora) means "few-flowered".[5] Distribution and habitatThis petrophile grows in low, open heathland on breakaway areas in a few locations in the Avon Wheatbelt, Murchison and Yalgoo biogeographic regions of Western Australia.[2][3] Conservation statusPetrophile pauciflora is classified as "Priority Three" by the Government of Western Australia Department of Parks and Wildlife[3] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[6] References
