The Douglas Fir. — In Gordon's " Pinetum," 2s. edition (1875), p. 26, 

 mention is made of a very remarkable variety of the Douglas Fir {Pseudo- 

 tsuga Douglasii). It was first observed by the late Mr. Standish, in his 

 nursery at Bagshot, among some seedlings gathered from a Douglas^Fir in 

 close proximity to some large Silver Firs. Mr. Gordon, judging from the 

 tenor of his remarks, must have seen this tree, which he says was 10 to 

 12 feet high in 1861, and alludes to it as an accidental seedling variety, 

 or " probably a hybrid between that kind and the Silver Fir, as its 

 general appearance and history would seem to indicate." I have lately 

 made enquiries as to the existence of this tree, but without success, 

 Mr. Standish's successors being unable to trace it. 



Abies = Silver Fir. — M. Croux produced in his nurseries near Sceaux 

 in 1871-1872, a hybrid Abies, to which the name of Abies Nordmanniana
