Description

Cassinia wilsoniae is an erect shrub that typically grows to a height of 0.75–1.8 m (2 ft 6 in – 5 ft 11 in) with its branchlets densely covered with woolly or cottony hairs. The leaves are needle-shaped, 10–20 mm (0.39–0.79 in) long and 0.7 mm (0.028 in) wide. The upper surface of the leaves is yellowish-green and more or lass glabrous and the lower surface is densely covered with cottony hairs. The flower heads are ochre-coloured, 3–4 mm (0.12–0.16 in) long and 2–3 mm (0.079–0.118 in) wide, each head with up to six florets surrounded by fifteen to eighteen involucral bracts 2–3 mm (0.079–0.118 in) long. Mostly between twenty and fifty heads are arranged in corymbs 20–70 mm (0.79–2.76 in) in diameter. Flowering occurs from February to April and the achenes are about 0.5 mm (0.020 in) long and with a pappus about 0.5 mm (0.020 in) long. [2]
