The Pará rubber tree ( Hevea brasiliensis), often simply called rubber tree, is a tree belonging to the family Euphorbiaceae.

By 1898, a rubber plantation had been established in Malaya, and today most rubber tree plantations are in Southeast Asia and some also in tropical Africa.

ParA rubber tree [pArA´] Pronunciation Key, large tree ( Hevea brasiliensis) of the family Euphorbiaceae ( spurge family), native to tropical South America and the source of the greatest amount and finest quality of natural rubber.
The tree is tapped by making careful incisions, as deep as possible without injuring the tree's growth, in a herringbone pattern or often in a lefthand spiral of 30° around the trunk, for the latex vessels spiral to the right at an angle of about 30° from the horizontal.
The size of the tree, the quality of the latex, and the number of taps possible varies with individual trees; the quantity of latex increases with the age of the tree, which may grow to a height of over 100 ft (30 m).
