Mahogany (Swietenia mahogani ) is a member of the family Meliaceae, which contains about 500 species of trees and shrubs native to tropical forests in the Americas, Africa, and Asia. Other common names for this species are the Spanish or West Indies mahogany. Various other species of trees have also been given the name mahogany, but the true mahogany is Swietenia mahogani. Mahogany is one of the most valuable of the tropical hardwoods because of its desirable qualities for the crafting of fine furniture.

Mahogany is native to humid tropical forests of the West Indies, Mexico, and Central America. Until rather recently, mahogany was especially abundant in forests in Honduras. However, the quantity of mahogany has been greatly reduced throughout its range by extensive logging. Although much reduced in abundance, mahogany is not yet considered an endangered species.

Mahogany is also indigenous to extreme southern Florida, where it occurs in some of the hardwood islands in the sawgrass wetlands of Everglades National Park, known locally as hammocks. However, mahogany reaches the northern limits of its range in southern Florida, and is rather sparse in that region. Because of its great value as lumber, mahogany has also been planted in suitable tropical climates beyond its native range.

Biology of mahogany

Mahogany grows as tall as about 66-98 feet (20-30 m), and can achieve a diameter of more than 24 inches (60 cm), exclusive of the large, basal buttresses the tree usually develops. Mahogany is a slow-growing tree, and it usually occurs in older, closed forests.

The wood of mahogany is very hard, heavy, and strong, and has a rich, red-brown color, with an attractive, crooked grain. Mahogany wood is among the worlds most prized and hardest-wearing timbers, and is principally used to manufacture fine furniture. The bark is dark brown and rather scaly.

Mahogonys dark-green leaves of mahogany are arranged in an alternate fashion on the twigs. They are compound, meaning six to eight oval-shaped, leathery leaflets arise from a single petiole. The entire leaf has a length of 4-7 inches (10-18 cm). Mahogany leaves are evergreen, that is, they are not shed all at once at some particular season.

The flowers of mahogany are small, only about 0.1 inch (2-3 mm) in diameter, with five greenish or whitish petals occurring in open clusters as a loose inflorescence. The flowers secrete nectar and are pollinated by insects. The fruits of mahogany are a reddish-brown capsule, which when ripe, split along five seams to shed the 0.8 inch- (2 cm) long seeds.

Uses of mahogany

Mahogany wood is used to manufacture fine furniture; it is valued because it is durable and can be carved with intricate details. It has a deep, rich color, attractive grain, stains beautifully, and glues solidly onto manufactured products. Mahogany was first imported to Europe in 1724, and it soon became famous because of the gracefully ornate furniture that Thomas Chippendale, an English cabinetmaker, began to make from the wood.

The most valuable raw product produced from mahogany wood is solid lumber, which can then be manufactured into expensive furniture and cabinets. However, solid mahogany is a very expensive material, and is becoming increasingly difficult to obtain. As a result, much mahogany is now used to manufacture a veneer product, in which a core of inferior wood is covered with a thin layer of mahogany. This composite material is glued together, and combines many of the desirable qualities of mahogany, especially its beautiful grain and color, with the cost savings associated with the use of other, relatively inexpensive species of trees.

Some related species

Some other species in the family Meliaceae are of commercial importance as sources of lumber, or as ornamental plants in horticulture.

The Spanish or cigar-box cedar (Cedrela odorata ) of Central and South America has a hard, durable, richly colored wood that is used as a substitute for the true mahogany in fine cabinetry and furniture, as is the

KEY TERMS

Buttress A structure that many trees of humid tropical forests grow at their base to stabilize the tree against the swaying forces of the wind. Buttresses can occur as broadened bases of the trunk, or as large, vertical projections from the base.

Tropical hardwood A generic term for a wide variety of species of tropical, angiosperm trees. Tropical hardwoods have a heavy, dense wood that is valuable for the manufacturing of lumber, or composite materials such as plywood. Mahogany and teak are among the most prized of the tropical hardwoods.

African mahogany (Khaya senegalensis ) grows in tropical forests on the west coast of Africa and is one of the many African species, including those in the genera Entandrophragma and Lovoa, which are substituted for the wood of the true mahogany. Some tropical hardwoods in other plant families are also used as substitutes for mahogany, for example, the Columbian mahogany Cariniana pyriformis, family Lecythidaceae.

The Chinaberry (Melia azedarach ) is native to southern Asia, but is grown as an ornamental plant in parts of the southern United States. The compound leaves of the Chinaberry can be longer than 20 inches (50 cm), and its purplish flowers are attractive and fragrant.

Species in the genera Azadirachta and Melia are used to manufacture botanical insecticides. Seeds of the trees Carapa guianensis and C. moluccensis are used to manufacture a minor product known as carapa fat, a thick white or yellow oil used in oil lamps, and sometimes as an insect repellant.
