Petrophile teretifolia is a species of flowering plant in the family Proteaceae and is endemic to southwestern Western Australia. It is a shrub with needle-shaped but blunt-pointed leaves, and oval to more or less spherical heads of hairy pink to mauve flowers.
Description
Petrophile teretifolia is an erect or spreading shrub that typically grows to a height of 0.1–2 m (3.9 in – 6 ft 6.7 in) and has glabrous branchlets and leaves. The leaves are needle-shaped but with blunt tips, 40–200 mm (1.6–7.9 in) long. The flowers are arranged in leaf axils or on the ends of branches in oval to more or less spherical heads about 15 mm (0.59 in) long, with a few involucral bracts at the base. The heads are sessile or on a peduncle 2–3 mm (0.079–0.118 in) long. The flowers are 17–25 mm (0.67–0.98 in) long, pink to mauve and hairy. Flowering occurs from September to January and the fruit is a nut, fused with others in a spherical, oval or elliptic head 15–25 mm (0.59–0.98 in) long.
