writing. M. Pierre lists and describes in manuscript, C. canephora 

 Pierre ex Froehner var. Hiernii Pierre mss. ex DeWild. ; C. cane- 

 phora Pierre ex Froehner var. Hinaultii Pierre mss. ex DeWild. ; C. 

 canephora Pierre ex Froehner var. kouilouensis Pierre mss. ex De- 

 Wild. ; C. canephora Pierre ex Froehner var. muniensis Pierre mss. 

 ex DeWild. ; C. canephora Pierre ex Froehner var. oligoneura Pierre 

 mss. ex DeWild. ; C. canephora Pierre ex Froehner var. Trillesii 

 Pierre mss. ex DeWild. ; C. canephora Pierre ex Froehner var. 

 Wildemannii Pierre mss. ex DeWild. In addition to these varieties, 

 one finds the variety opaca Pierre in Bull. Jard. Col. Nogent-sur- 

 Marne (1904) 117 f .c. ; and the variety sankuruensis DeWild. in 

 DeWild. Miss. Laurent 3 (1906) 333 t. 77 f. 52, 53. 



It seems probable, as M. Pierre himself suggests, that these varie- 

 ties will be placed in synonymy by further study or at best, I believe, 

 will only be elevated to forms of C. canephora Pierre ex Froehner 

 or subvarieties of the distinct variety C. canephora Pierre ex Froeh- 

 ner var. kouilouensis Pierre mss. ex DeWild. I find myself unable 

 to obtain sufficient material to straighten out this obvious tangle. 



Use: — C. canephora Pierre ex Froehner is superior to many coffees 

 in productivity and in the quality of the infusion prepared from its 

 seeds. Its seeds are widely used wherever it is indigenous, for the 

 seeds C. arabica L.
