Tasmannia is a genus of woody ever green flowering plants, of the family of Winteraceae.There are 40 species of Tasmannia native to Australia, Borneo, New Guinea and Philippines.

The Winteraceae are associated with the humid southern hemisphere. The members of the family generally have aromatic bark and leaves, and are used to extract their essential oils.

The peppery-flavored fruits and leaves (esp. dried) of this genus are increasingly used as a condiment in Australia.

‘Tasmanian pepper’ or ‘mountain pepper’ was the original pepper bush used by colonial Australians. Introduced into cultivation in Cornwall, U.K., to become the ‘Cornish pepper leaf’ associated with Cornish cuisine.

It has large peppery berries which are also high in antioxidants. Wild strains of mountain pepper are rendered safe so that asafrole-free strains of mountain pepper have been selected for the spice trade.

Dorrigo Pepper or Tasmannia stipitata is also sold as a spice. It was the original pepper bush used in specialty native food restaurants in the 1980s. Dorrigo pepper is safrole free but has a strong peppery flavor.
