In addition to these the " African Satinwood," " Ainyassan-gwe," a species 

 of Cassia (Natural Order LeguminoscB), is a large tree, yielding a bright 

 canary-yellow wood, which is firm and close in texture, and should prove

 Order Leguminosce), proved not to be durable, and is, therefore, valueless as 

 a substitute for the Dcmerara wood. 



Among a series of timbers from Uganda recently described by Mr. Stone, ^ 

 the most important is, perhaps, " Muvube " {GMorophora rustica Benth. ; 

 Natural Order Mordcece), alUed to the Iroko of the West Coast, and a yellowish- 

 brown, extremely hard and durable wood.
