Turpentine Tree, _burseræ gummifera,_ belongs to the order diœcia, class polygamia; the calyx is triphyllous, the corolla three-leaved, and the seed-vessel tri-valved. It grows very fast, and sometimes attains a great height. The trunk is of a bright brown, sometimes mottled with red, and presents a glossy appearance; the leaves are broad, and of a deep green. It is so tenacious of life, that it will bud and blossom after being cut up and planted as posts. Nickel, or nickar tree, _guilandina,_ is a curious genus of the monogynia order, decandria class of plants. There are two species, the _bonduc,_ or yellow nickar, and the _bonducella,_ or grey nickar. They are both of them climbing plants, sometimes attaining the height of fifteen or eighteen feet. The flowers are quinquefid, the petals of a yellow colour, and growing from the wings of the stalks. The germen becomes an oblong pod, thickly covered with slender spines, two-valved, and containing two hard seeds of the size and shape of a marble; those of the bonduc are yellow; the bonducella, of a beautiful grey colour, from whence their respective names. Locust-Tree, _hymenæa courbaril;_ order monogynia, class decandria. This tree sometimes rises to the height of sixty or seventy feet, in a straight column-like trunk, of two or three feet in circumference, covered with an ash-coloured bark. The leaves are of a dark-green, and the flowers, divided into five segments, and of a pale purple, streaked with yellow, come out in loose spikes at the end of the branches. The germen becomes a thick fleshy pod, of four or five inches long, covered with a hard brown shell, and containing a farinaceous substance, in taste something like gingerbread, but of a most intolerable odour, but which is eaten heartily by the negroes. In it is seated two or three hard brown seeds, of about the size of marbles, but of an oblong shape. The timber is used for making bedsteads, &c., while from the roots a dark transparent gum may be procured, which, when dissolved with spirits of wine, forms an excellent varnish.
