eludes the spruces, firs (Abies), pines and larches) 

 "in a more exact sense it has been transferred to the 

 spruces and silver firs, the pncra Picca and Abu-s 

 of most modern botanists." 



Elwcs and Henry, in their monumental work / he 

 Trees of Great Britain and Ireland (published 1906- 

 1912), largely follow the practice of restricting the 

 term "fir" to the genus Abies, but apply the name 

 "common silver fir" to the species commonly grown 

 in Europe (Abies pectinata) and the name "balsam 

 fir" to the tree commonly known by this name (or 

 simply "balsam") on this continent. They spca': 



also of the "spruce firs," but use the term "hem- 

 lock" instead cf the "hemlock spruce" of other 

 writers, though they .speak of the common Eastern 

 American species (Tsuga canadensis) as the "hem- 

 lock or hemlock spruce." "Douglas fir" is the 

 name they adopt for the famed western species 

 (Pseudotsuga mucronata or Douglasii). 



From the standpoint of simplicity the American 

 terminclogy has a great advantage; but it is hard 

 to change long-established usage, and the British 

 usage is still indefinite though doubtless time will 

 effect the change in nomenclature.
