Petrophile brevifolia

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.

This petrophile grows in shrubland, heath and woodland and is widespread and common from Kalbarri National Park to Ongerup in the southwest of Western Australia.
