Creenheart , a tree belonging to the laurel family and of the genus nectandra. Botanists do not agree as to the species, some calling it N.Rodioei, while others consider it a variety of N. leucantha. It is found in several of the "West India islands and in various parts of South America, where it forms a large tree, often 50 or 60 ft. high and 2 or 3 ft. in diameter; the alternate polished leaves are from 4 to 9 in. long; the flowers, in loose panicles, consist of a wheel-shaped calyx, no petals, nine fertile stamens, and a single pistil; the divisions of the calyx fall away, and its tube remains as a small cup which supports the berry. The bark has been used as a substitute for cinchona, and, under the name of bibiru or bebeeru, has been somewhat employed in medicine. It contains an active principle called bebeerine, which is not to be confounded with berberine. The great value of the tree is in its timber, which is sent from Demerara to England, where from its hardness it is substituted in some cases for lignum vitae; it is considered one of the most valuable timbers for ship building on account of its great strength and durability.
