Petrophile stricta is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is an erect, spreading shrub with needle-shaped, sharply-pointed leaves, and oval heads of hairy, pink to cream-coloured flowers.
Petrophile stricta is an erect, spreading shrub that typically grows to a height of 0.6–1.6 m (2 ft 0 in–5 ft 3 in) and has glabrous branchlets and leaves. The leaves are needle-shaped, sharply pointed and 45–135 mm (1.8–5.3 in) long. The flowers are arranged at the ends of branchlets in oval heads up to about 20 mm (0.79 in) in diameter on a peduncle 6–12 mm (0.24–0.47 in) long, with deciduous, linear involucral bracts at the base. The flowers are 10–12 mm (0.39–0.47 in) long, pink to cream-coloured and hairy. Flowering occurs from October to December and the fruit is a nut, fused with others in an oval head 20–47 mm (0.79–1.85 in) long. [2] [3] [4]
Petrophile stricta was first formally described in 1990 by Donald Bruce Foreman in the journal Muelleria from and unpublished description by Charles Gardner. [4] [5] The specific epithet (stricta) means "straight, erect or rigid". [6]
This petrophile grows in sandy shrubland and scrub in sandy-gravelly soils over laterite on sandplains, ridges and low hills in the drier, inland parts in the Avon Wheatbelt, Coolgardie and Mallee biogeographic regions in the south-west of Western Australia. [2] [3]
Petrophile stricta is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife. [3]
