Atherosperma moschatum, the southern sassafras or blackheart sassafras, is an evergreen tree native to the cool temperate rainforests of Tasmania, Victoria, and New South Wales in Australia. It is common in the rainforests of Tasmania and Victoria, but more scattered and rare in the higher altitudes of eastern New South Wales. The northernmost area is at Mount Grundy, west of Port Macquarie.
The southern sassafras was first described by French naturalist Jacques Labillardière in 1806, and was the only member of the genus Atherosperma. A subspecies, A. m. subsp. integrifolium, has been considered a separate species. Its generic name is derived from the Ancient Greek ather "awn", and sperma "seed", from the hairs on the fruit, and the specific epithet moschatum is the Latin adjective meaning "musk-scented", from the smell of the bark. It is a member of the small family Atherospermataceae along with several other Australian rainforest trees including yellow sassafras (Doryphora sassafras). . Its closest relative is the monotypic genus Nemuaron, endemic to New Caledonia.
The southern sassafras is a small to medium-sized tree, growing around 6 to 25 m tall. However, in Tasmania, it can reach heights exceeding 40 m and a width of 1 m. It can be identified by the conical shape, the pale green leaves, and fragrant scent.
The bark is grey to light brown, with numerous lenticels, raised bumps and ridges. The leaves are 3 to 10 cm long and 8 to 25 mm wide, margins are coarsely toothed, but the northern population in Monga National Park, the Blue Mountains, Barrington Tops and at Mount Grundy has narrow, mostly entire leaves. Leaves, twigs, and flowers are fragrant, of a pleasant nutmeg scent.
