Hevea brasiliensis, the Pará rubber tree, sharinga tree, seringueira, or, most commonly, the rubber tree or rubber plant, is a flowering plant belonging to the spurge family Euphorbiaceae.

Hevea is a genus of flowering plants in the spurge family, Euphorbiaceae, with about ten members. It is also one of many names used commercially for the wood of the most economically important rubber tree, H. brasiliensis.

Vaupés River is a tributary of the Rio Negro in South America. It rises in the Guaviare Department of Colombia, flowing east through Guaviare and Vaupés Departments. It forms part of the international border between Colombia and the Amazonas state of Brazil. On the border it merges with the Papurí River and becomes known as the Uaupés.
