Description
Petrophile drummondii is a shrub that typically grows to a height of 1.0–1.5 m (3 ft 3 in – 4 ft 11 in) and has more or less glabrous young branchlets. The leaves are 20–50 mm (0.79–1.97 in) long on a petiole 10–26 mm (0.39–1.02 in) long and pinnate with rigid, sharply-pointed and needle-like pinnae about 20 mm (0.79 in) long. The flowers are arranged on the ends of branchlets in sessile, more or less spherical heads 30–40 mm (1.2–1.6 in) long, with many glabrous, egg-shaped to lance-shaped involucral bracts at the base. The flowers are about 20 mm (0.79 in) long, fragrant, sticky, yellow and covered with short hairs. Flowering occurs from August to December and the fruit is a nut, fused with others in an oval head 25–30 mm (0.98–1.18 in) long.[2][3]
