Description
Cassinia collina is a shrub that grows to 2 m tall. The branches are brownish and hispidulus. The leave blades are linear to narrowly ovate, 3 to 7 cm long and 0.15 to 0.4 cm wide, with a petiole 1 mm long, and an apiculate apex. There are minute, rough hairs on the adaxial surface of the leaf and white tomentose hairs on the abaxial surface. The leaf margins are recurved or revolute almost to the midrib. The inflorescences occur in panicles which are up to 16 cm long. The involucres are straw coloured and 4 mm long. Each involucre embraces seven florets. The achenes are 0.75 mm long, pubescent, angular or nearly cylindrical. The pappus is about 2 mm long.
Cassinia collina has been described as closest to C. quinquefaria, however the latter differs in its more glabrous character, smaller and narrower leaves, with involucre embracing only 5 smaller florets. The leaves of C. collina are similar to those of C. longifolia and C. compacta, however both have corymbose, not paniculate inflorescences (White, 1942; Stanley and Ross, 1986).

Habitat
Cassinia collina occurs in open forest on stony soils and sandy loams. In Mt Walsh National Park the species has been recorded growing on rocky creek banks, in fine-grained granite. It has been recorded in tall woodland with Eucalyptus dura, Corymbia trachyphloia and Acacia blakei. It has also been recorded growing in shallow sandy soils in woodland dominated by Corymbia citriodora, E. acmenoides, C. trachyphloia and E. crebra (Wang, 1999; Queensland Herbarium, 2011).
Reproduction
Flowering has been recorded from April to June and in September-October (Wang, 1999; Queensland Herbarium, 2011). The fruiting period is unknown (Wang, 1999).
Threatening processes
There are no substantial threatening processes recorded in the literature. Potential threatening processes include habitat clearing on private land (Wang, 1999).
Status notes
Cassinia collina is listed as Vulnerable in Queensland under the Nature Conservation Act 1992.
Management documents
Wang, J. (1999). Cassinia collina Species Management Profile, Department of Natural Resources, Queensland.
Management recommendations
Management recommendations include the establishment of protective buffers that excludes clearing in areas where C. collina occurs, with all C. collina to be at least 20 m inside the protective buffer and adaptive management techniques to be put in place during timber harvesting (Wang, 1999).
Notes
Occurs in the following Queensland pastoral districts: Wide Bay, Port Curtis (Bostock and Holland, 2010).
