Petrophile brevifolia is a species of flowering plant in the family Proteaceae and is endemic to southwestern Western Australia. It is a shrub with cylindrical, sharply-pointed leaves, and spherical heads of hairy yellow, cream-coloured or white flowers.
Description
Petrophile brevifolia is a low, multi-stemmed, erect, or spreading, non-lignotuberous shrub that typically grows to a height of 0.2–2 m (7.9 in – 6 ft 6.7 in) and has glabrous branchlets and leaves. The leaves are needle-shaped, 10–50 mm (0.39–1.97 in) long with a sharply-pointed tip about 2 mm (0.079 in) long. The flowers are arranged on the ends of branchlets in sessile, spherical heads 10–15 mm (0.39–0.59 in) in diameter, with many linear or tapering involucral bracts at the base. The flowers are 12–20 mm (0.47–0.79 in) long, yellow, creamy yellow or white and hairy. Flowering occurs from June to December and the fruit is a nut, fused with others in an oval to spherical head about 10–20 mm (0.39–0.79 in) long.
