Sorry, no etymologies found.
For them, of course, the term Hevea brasiliensis had no meaning.
A variety of interesting trees occurs in the hill woodlands of the Upper Marmelos and Middle Tapajós Rivers including the dwarf rubber tree, Hevea camporum, the elegant palm, Euterpe longibracteata, the enormous Huberodendron ingens, and rare monotypic Brachynema ramiflorum.
The tallest trees that emerge from the canopy include Ceiba pentandra, Terminalia amazonica, Cedrelinga catenaeformis, Carapa guianensis, and Hevea guianensis var. lutea, a type of rubber tree.
Other large trees, some with commercial value, on the terra firme are the Brazil nut (Bertholletia excelsa), sucupira (Bowdichia virgilioides), and rubber (Hevea spruceana).
A characteristic high campinarana forest association includes the tree species Eperua leucantha, E. purpurea, Micrandra sprucei, Catostemma sclerophyllum, Hevea viridis, and Macrolobium unijugum.
Economically important trees on the terra-firme are the Brazil nut Bertholletia excelsa, Bowdichia virgilioides, and rubber Hevea spruceana.
The culture of Hevea trees replacing rice fields across the country to provide 'black gold' to our 'big brother' is an ecological disaster, and Lao minorities are displaced.
Hevea trees appeared in the rain forest "at a rate of two or three per acre," Mr. Jackson writes, "as if someone had scattered them from cloud level like a giant Johnny Appleseed."
In 1876, he found a treasure: the seeds of the Hevea brasiliensis tree, which produced "white gold," as latex was known in an industrializing world that was mad for rubber.
Until Wickham gathered tens of thousands of Hevea seeds and spirited them out of Brazil to England, rubber trees were found only in a narrow equatorial belt along the Amazon.
