Description

Cassinia complanata is an erect or semi-erect shrub that typically grows to a height of 0.9–1.5 m (2 ft 11 in – 4 ft 11 in), its branches sticky and densely covered with glandular hairs. The leaves are narrow linear to needle-shaped, 9–40 mm (0.35–1.57 in) long and 0.74–1.0 mm (0.029–0.039 in) wide, with sticky, cottony hairs on the lower surface. The flower heads are 3.3–4.2 mm (0.13–0.17 in) long and 2–3 mm (0.079–0.118 in) in diameter, each with five or six florets surrounded by five overlapping whorls of white involucral bracts. The heads are arranged in a corymb 5–40 mm (0.20–1.57 in) in diameter. Flowering occurs in January and February and the achenes are 1 mm (0.039 in) long with a bristly pappus about 2 mm (0.079 in) long. [2]

Taxonomy

Distribution and habitat

This cassinia grows in woodland and mallee in Victoria, from the Big Desert and Little Desert areas to the Grampians, and in south-eastern South Australia . [2]
