The seeds are used for ornamental purposes. 



The wood, which yields a red dye, is used for house building and 

 cabinet work, hard and durable, weighing unseasoned 62 lbs., and 

 seasoned 56 lbs. per cubic foot (Beddome, Fl. Sylv. t. 46). 



The tree is easily raised from seed, and grows quickly. Trees in 

 the Botanic Garden, Old Calabar, were bearing seeds in 1899.
