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.
Zenú The Zenú or Sinú is an Amerindian tribe in Colombia, whose ancestral territory comprises the valleys of the Sinu and San Jorge rivers as well as the coast of the Caribbean around the Gulf of Morrosquillo. These lands lie within the departments of Córdoba and Sucre.
