Petrophile arcuata is a shrub that typically grows to a height of 0.7–1.5 m (2 ft 4 in – 4 ft 11 in) and has more or less glabrous branchlets. The leaves are cylindrical, 5–15 mm (0.20–0.59 in) long and 0.7–1.0 mm (0.028–0.039 in) wide. The flowers are arranged in sessile, oval to spherical heads about 12 mm (0.47 in) in diameter, with a few glabrous egg-shaped involucral bracts at the base. The flowers are about 12 mm (0.47 in) long, creamy yellow to yellow and hairy. Flowering occurs from September to October and the fruit is a nut, fused with others in an more or less spherical head 10–15 mm (0.39–0.59 in) in diameter.
