Petrophile crispata is a species of flowering plant in the family Proteaceae and is endemic to southwestern Western Australia. It is a shrub with pinnately-divided leaves with sharply-pointed tips, and oval heads of glabrous, yellow flowers.
Petrophile crispata is a shrub that typically grows to a height of and has hairy branchlets that become glabrous with age. The leaves are long on a petiole long, and pinnately-divided with rigid pinnae long, each with a sharply-pointed tip. The flowers are arranged on the ends of branchlets, in sessile, oval heads up to long, with deciduous, egg-shaped involucral bracts at the base. The flowers are about long, yellow and glabrous. Flowering occurs from September to November and the fruit is a nut fused with others in a oval head long.[1]
Petrophile crispata 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 near King Georges Sound in 1829.[2] [3] The specific epithet (crispata) means "curled" or "crinkled", referring to the hairs on the branchlets.[4]
This petrophile grows in shrubland and woodland between Cranbrook, Cheyne Bay near Cape Riche and Woodanilling in the Avon Wheatbelt, Esperance Plains, Jarrah Forest and Mallee biogeographical regions of southwestern Western Australia.
Petrophile crispata is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
