Tasmannia is a genus of woody, evergreen flowering plants of the family Winteraceae. The 40 species of Tasmannia are native to Australia, New Guinea, Celebes, Borneo, and the Philippines. The Winteraceae are magnoliids, and are associated with the humid Antarctic flora of the Southern Hemisphere. The members of the family generally have aromatic bark and leaves, and some are used to extract essential oils. The peppery-flavored fruits and leaves (especially dried) of this genus are increasingly used as a condiment in Australia. The peppery flavour can be attributed to polygodial.
