GREENHEART; from Jamaica, Demerars, and the Brazils, bears a general resemblance to cocoa-wood both in size and bark, but the latter has a redder tint Greenheart when first cut is of a light green brown, and striped, but it changes to the colour of Lignum-vitae and is by some considered to be pernicious. It is used for turnery and other works, but it3 texture is coarse, and it will not cleave at all profitably.

Greenheart used in ship-building is entirely different from the above, and runs into several varieties.

Dr. Bancroft describes Greenheart, or the Sipiera tree, to be in size like the locust-tree, say 60 or 70 feet high: there are two species, the black and the yellow, differing only in the colour of their bark and wood. He says there is also a purple-heart wood, of a bright crimson colour, but which changes to purple, and is esteemed more valuable than the preceding. - Dr. Bancroft's Guiana, p. 68-9.

These descriptions exactly agree with Mr. Fincham's specimens described as Greenheart, and black and brown Greenheart; they are large heavy woods and of olive green even tints, varying from very pale to dark. These, as well as the Purple-heart woods, are used for ship-building, but more particularly in their native countries; they appear excellent also for the lathe.

The greenheart of Jamaica and Guiana, is the Laurus Chloroxylon of botanists; it is also called Cogwood in the former, and Sipieri in the latter locality.
