Small genus of South American trees yielding latex.
1 Patagonia's 'green' wetsuits use renewable natural rubber from hevea trees grown in compliance with Forest Stewardship Council standards.
2 The formation of the coagulum of the hevea , or of real caoutchouc, is nevertheless much more rapid in contact with the air.
3 Acids precipitate the caoutchouc from the milky juice of the euphorbiums, fig-trees, and hevea ; they precipitate the caseum from the milk of animals.
4 In going to the embarcadero, we caught on the trunk of a hevea * (* One of those trees whose milk yields caoutchouc.)
5 This is Nature's clever scheme to spread the Hevea family.
6 The Hevea tree grows sixty feet tall, and when full grown is eight or ten feet around.
7 * (* The pellicles deposited by the milk of hevea , in contact with the atmospheric oxygen, become brown on exposure to the sun.
