Description

Petrophile phylicoides is a shrub that typically grows to a height of 0.2–1.5 m (7.9 in – 4 ft 11.1 in) and has hoary young branchlets. The leaves are needle-shaped but not sharply-pointed, 6–15 mm (0.24–0.59 in) long and mostly curved upwards. The flowers are arranged on the ends of branchlets in sessile, more or less spherical heads about 10 mm (0.39 in) in diameter, with tapering involucral bracts at the base. The flowers are about 12 mm (0.47 in) long, glabrous and yellow. Flowering mostly occurs from September to December and the fruit is a nut, fused with others in a spherical head up to 28 mm (1.1 in) in diameter.

The specific epithet (phylicoides) means "like a plant in the genus Phylica".
