Swietenia macrophylla and S. humilis are referred to as Mahogany, a tropical evergreen or deciduous tree that can attain heights of 150 feet. Mahogany is a member of the Meliaceae, which includes other trees with notable wood for cabinet making. Swietenia macrophylla is world renowned for its beautifully grained, hard, red-brown wood. It has been harvested since 1500 A.D. for its wood, with large branches being in higher demand than the trunk. This is due to the closeness of the grain in the branch's wood. Mahogany is used for furniture, fixtures, musical instruments, millwork, cars, ships, boats, caskets, airplanes, foundry patterns, veneer, and plywood (Hill, 1952).
