In all the above cases we have the same or very closely allied species 

 involved, viz., Abies Pinsapo, with its blunt leaves arranged on all sides 

 of the stem and all nearly of the same size, and .4. Nordmanniana 

 (perhaps a form of A. cxcelsa), and nearly allied to A. cepJialonica. In 

 all these trees the flat leaves are nearly in one horizontal plane, or the 

 median and uppermost leaves are upturned, sometimes all nearly equal 

 in length, or the upper ones shorter than the lower ones. 



Professor Sargent's account of the supposed hybrid between A. 

 lasiocarpa and A. amahilis runs as follows : — 



" On a ridge of the Olympic mountains separating the waters of the 

 Soldue from those of the Quillihute, I found on August 19, 1896, at an 

 elevation of four thousand five hundred feet above the sea, an Abies of

from sixty to eighty feet in height, growing with Abies lasiocarpa and 

 A. amabilisy with the slender spire-like head and the foliage of the former 

 and the cones of the latter. It was, perhaps, a natural hybrid between 

 these species." Sargent, " Silva," xii. 126 adnot. (1598). 



PiCEA : The only hybrid known to me in this genus is the one for 

 specimens of which I am indebted to M. Moser, and which I received 

 from him under number " 5." See (fig. 29) p. 105.
