The wrinkled cassinia is a perennial spreading to erect shrub that grows to about 3 m tall and is often densely multi-branched from the base. This species is known from three regions: one in south western Victoria, one in south eastern South Australia, and another on the central north coast of Tasmania. The wrinkled cassinia is known from several small subpopulations of around one to 20 individual plants, though one large population, of approximately 300 individuals, occurs in Tasmania. All wrinkled cassinia populations are associated with water courses and can be found in damp seasonally wet, low open-forest or dense, low heathy woodland or scrub. Land clearing has resulted in the loss, fragmentation and modification of natural wetlands where subpopulations of this species are likely to have occurred. This continues to be one of the known threats to the wrinkled cassinia.
