dantly in the eastern forest along the Chari river, Africa, between 

 8° and 8°3o' latitude north. It is found also in the region of 

 Bata (West Central Sea Coast) and commonly in the region of 

 Kotto along the banks of the Oubanqui river, at an altitude of 

 500 M. to 800 M. 



C. excelsa A. Chev. is never found in flooded areas. It is admir- 

 ably adapted to the arid regions of the Sudan. It has recently 

 been introduced into the Trinidad Botanic Gardens, and is reported 

 to be of considerable value. The plots of C. excelsa A. Chev. w^hich 

 were planted at Kampala, Uganda, in 1915 and 1916, have not, 

 however, yielded as well as C. arabica L. and C. robusta Linden. 

 In March, 1922, the beans of C. excelsa A. Chev. were valued at 

 only about forty-seven shillings per cwt. on the London market. 

 Its seeds produce an agreeably flavored beverage. 



Use: — It is cultivated commercially for use as a filler and as a 

 substitute for the seeds of C. arabica L.
