Entandrophragma

Entandrophragma is a genus of flowering plants in the mahogany family, Meliaceae, native to tropical Africa. The genus comprises several large hardwood trees, among which Entandrophragma utile (commonly known as sapele) and Entandrophragma cylindricum (commonly known as sipo) are the best known for their timber.

Description and distribution: These trees grow in tropical forests across West and Central Africa, from Guinea to Angola. They typically produce substantial trunks and are valued for straight, tall forms that contribute to their usefulness as timber species. The genus is part of the diverse Meliaceae, a family that includes several other genera with economically important hardwoods.

Timber and uses: The wood of Entandrophragma species is heavy and hard, with a fine to interlocked grain. It finishes well and is durable in many applications. Sapele and sipo timbers are widely used for high-quality furniture, cabinetry, interior joinery, veneer, and plywood, and are also used in musical instruments and, historically, in boatbuilding. In commercial markets, sipo is often marketed as a close substitute for genuine mahogany due to its similar appearance and working properties.

Conservation: Overexploitations and habitat loss have affected some Entandrophragma species. Sustainable forestry practices and trade controls—such as those under CITES for certain species—are relevant to the genus to balance timber value with conservation considerations.
