Cassinia copensis is an erect, multi-stemmed shrub that typically grows to a height of and is strongly aromatic. The leaves are cylindrical long and about wide with the edges rolled under. The upper surface of the leaves is sticky with a sunken midrib and the lower surface is densely covered woolly white hairs. The flower heads are about long, each with five or six creamy-white florets surrounded by overlapping, opaque involucral bracts. The heads are arranged in a flattened corymb of one hundred to two hundred florets. Flowering occurs in December and the achenes are about long with a pappus of about twenty bristles long.[1]
Cassinia copensis was first formally described in 2004 by Anthony Edward Orchard in Australian Systematic Botany from specimens he collected near Copes Creek on the road between Bundarra and Inverell in 2004.[2]
This species of Cassinia grows in forest and woodland in the watershed of Copes Creek in New South Wales and near Wallangarra in Queensland, near the border with New South Wales.[1]
