Century Dictionary and Cyclopedia
- n. A genus of dicotyledonous plants, of the natural order Euphorbiaceæ, tribe Crotoneæ, the type of Baillon's tribe Heveæ. It is characterized by having 3-foliolate leaves; a lax panicle of flowers, of which the calyx is 5-toothed or with 5 short lobes, and no corolla; stamens 5 to 10, with the filaments united in a column; and 3-valved capsular fruit. About 10 species are known, natives of tropical Brazil and Guiana. This genus furnishes the most valuable caoutchouc or india-rubber exported from South America. The best is obtained from
H. Brasiliensis . The seeds of these trees are poisonous to man and quadrupeds, but are harmless to and greedily eaten by birds. Prolonged boiling deprives them of their poison and renders them palatable.
GNU Webster's 1913
- n. A small genus of South American trees yielding latex. It includes the rubber tree, Hevea brasiliensis, originally found in South America, but now used for production of rubber world-wide.
