Thompson, 1. 



The timber of this tree is exported to Europe as " Mahogany," 

 according to Mr. Thompson. Until flowers are known, the systematic 

 position of T. utile must remain a little doubtful ; the fruit, 

 however, agrees fairly well with that of Triplochiton, and the 

 difference in the leaves is no greater than is found among the 

 species of Stcrculia. Native name " Nyankom.
