What is or are the proper botanical name or names ? 



I shall first attempt to answer questions two and three as applied to the 

 cultivated Bolivian leaf (" E. Bolivianiim Burck " ), first anticipating ques- 

 tion No. I so far as to express the opinion that there is no ground for as-

suming that this differs in origin or species from the large brown cultivated 

 Peruvian (" Huanuco ") leaf, to which the name E. coca lyamarck has 

 been universally applied. 



If one is E. coca, the other is, and the name "^. Bolivianum Burck" 

 could not stand, without showing that none of the leaves used in the man- 

 ufacture of cocaine can properly bear the name of E. coca, and that no 

 previously given name is applicable to them. The latter view is by no 

 means extreme. It has been suggested by more than one writer and be- 

 lieved by many more, and at one time during this study, such a conclu- 

 sion seemed to myself inevitable. 



The name E. coca was published in 1786, in Lamarck's Dictionary II., 

 393, where a very full description was given.
