the Tacca and the Zenobia are both native to South America?
Tacca The genus "Tacca", which includes the batflowers and arrowroot, consists of flowering plants in the order Dioscoreales, native to tropical regions of South America, Africa, Australia, Southeast Asia, and various oceanic islands. In older texts, the genus was treated in its own family Taccaceae, but the 2003 APG II system incorporates it into the family Dioscoreaceae. The APG III and APG IV systems continue to include "Tacca" in Dioscoreaceae.
Tasmannia Tasmannia is a genus of woody, evergreen flowering plants of the family Winteraceae. The 40 species of "Tasmannia" are native to Australia, New Guinea, Sulawesi, 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.
