 and C. acuminata Schott et Endl. ( possibly identical) are the source 

 of the kola nuts which form a principal article of trade in W. Africa. 

 The nuts contain much caffein, and when chewed confer considerable 

 power of sustaining fatigue ; they are consequently a staple in the 

 diet of the negroes (cf. Erythroxylon). The tree is as yet rarely cult., 

 but is very common in W. Afr. The nuts are skinned after keeping 

 for a few days, and packed between 1. to keep them damp.
