Few words of recent introduc- 

 tion are in such common popular 

 use as the name of this tropical 

 African tree, because of the ex- 

 tent to which the active stimulant 

 contained in its fruit is used or 

 supposed to be used in summer 

 beverages. Like the mate or Paraguay tea of South America, 

 it enjoys the repute of enabling men to sustain long periods 

 of exertion with little or no food. 

 Twigs brown, stellate-scurfy when very young. C. acuminata.
