NOMENCLATURE. 



Thk first part of the name of a plant designates the genus to 

 which it belongs, or is generic; the second part belongs to the 

 particular species, or is specific ; but both words are necessary 

 for the designation of the plant or species. The literature of 

 systematic botany is so voluminous, however, that, in order to 

 identify the plant names and to aid in tracing them to their 

 origins, it is necessary to cite the author of the name along with 

 the name itself. In accordance with the method in Gray's 

 botanies, this author is understood to be the one who first used 

 the two names together ; that is, he is the author of the com- 

 plete name or combination and not necessarily of either part 

 of it. The full names of the authors most frequently cited in
