MAHOGANY. (Swietenia, Khaya, Soymida, Cedrela, etc.)
There are three principal mahogany trees: the Central American or true mahogany (Swietenia mahogani), the African mahogany (Khaya senegalensis), and the Indian mahogany (Soymida febrifuga). There are also minor species called mahoganies.[61] American mahogany was originally divided by dealers into Spanish and Honduras wood, the former from the then Spanish-American possessions. A considerable supply now comes from Mexico, taking name from port of shipment; as, Frontera, Laguna, Santa Ana, Tecolutla, Minatitlan, and Tonala, desirability being much in the order named. The African field is the latest and probably most important, very large quantities of its wood being distributed through English markets.
