Petrophile globifera is a species of flowering plant in the family Proteaceae and is endemic to southwestern Western Australia. It is a shrub with more or less cylindrical leaves and elliptic to spherical heads of cream-coloured to pale yellow flowers on the ends of branchlets.
Petrophile globifera is a shrub that typically grows to a height of 0.7–1.2 m (2 ft 4 in – 3 ft 11 in) and has hairy, yellow-grey to reddish-brown young branchlets. The leaves are more or less cylindrical, 3–6 mm (0.12–0.24 in) long, about 0.8 mm (0.031 in) wide with a pointed tip. The flowers are arranged on the ends of branchlets in sessile, elliptic to spherical heads 10–18 mm (0.39–0.71 in) in diameter, with narrow egg-shaped, sticky involucral bracts at the base. The flowers are 10–15 mm (0.39–0.59 in) long, cream-coloured to pale yellow and hairy. Flowering occurs from August to October and the fruit is a nut, fused with others in an elliptic or spherical head 9–12 mm (0.35–0.47 in) long and 10–14 mm (0.39–0.55 in) wide.[2][3]
Petrophile globifera was first formally described in 2011 by Barbara Lynette Rye and Kelly Anne Shepherd in the journal Nuytsia from material collected by Donald Bruce Foreman in 1984.[2][4] The specific epithet (globifera) means "sphere-bearing", referring to the flower heads.[2][5]
This petrophile mainly grows in sand in the area between Morawa, and Pithara.[2]
Petrophile globifera 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]
