Cassinia ozothamnoides

Cassinia ozothamnoides, commonly known as cottony haeckeria, is a species of flowering plant in the family Asteraceae and is endemic to Victoria, Australia. It is an erect shrub with hairy branchlets, linear leaves and corymbs of up to two hundred flower heads.

Description
Cassinia ozothamnoides is an erect shrub that typically grows to a height of up to 2 m with its branchlets densely covered with woolly white hairs. The leaves are linear, 20–30 mm long and about 1.0 mm wide. The upper surface of the leaves is dark green, the edges rolled under, the lower surface is densely covered with white, woolly hairs and there is a small point on the end. The flower heads are 4–5 mm long, each with five or six florets surrounded by 12 to 18 overlapping involucral bracts. Between 50 and 200 heads are arranged in corymbs 50–90 mm in diameter. Flowering occurs from October to March and the achenes are 1.0–1.2 mm long with a pappus of up to sixteen bristles 1.5–1.8 mm long.

Taxonomy and naming
This species was first formally described in 1855 by Ferdinand von Mueller who gave it the name Haeckeria ozothamnoides in his Definitions of rare or hitherto undescribed Australian plants. In 2004, Anthony Edward Orchard changed the name to Cassinia ozothamnoides in Australian Systematic Botany. The specific epithet (ozothamnoides) means "Ozothamnus-like".

Distribution
Cassinia ozothamnoides grows in open forest at altitudes from 170 to 300 m in central Victoria, often in disturbed sites.
