The name mahogany is use when referring to numerous varieties of dark-colored wood, originally the wood of the species Swietenia mahagoni, known as West Indian or Cuban Mahogany. It was later used also for the wood of Swietenia macrophylla, which is closely related, and known as Honduras Mahogany. Today, all species of Swietenia are listed by CITES, and are therefore protected. Species of Swietenia cross readily when they grow in proximity, the hybrid between S. mahagoni and S. macrophylla is widely planted. Mahogany is also the national tree of Dominican Republic. It is also part of the national seal of Belize which was known as British Honduras before independence.
