"Swietenia macrophylla", commonly known as Big-leaf mahogany, is a species of plant in the Meliaceae family. It is one of three species that yields genuine mahogany timber, the others being "Swietenia mahagoni" and Swietenia humilis". The species is also known under other common names, including Broad-leaved mahogany, Brazilian mahogany, Large-leaved mahogany, Genuine mahogany, Tropical American mahogany, and Sky fruit, among others. Big-leaf mahogany is a large-statured canopy emergent tree at maturity. Stem diameters as large as 3.5 metres have been reported, with buttresses rising 5 or more metres up the base of the tree and crowns 70 metres tall and up to 40 metres across. Mature tree crowns tend to be irregular in shape and composed of relatively few large primary branches.
