A very distinct variety with much longer leaves, and of a deeper 

 green, than the species, with the cones much shorter, but broader and 

 less pointed ; the extended bracts are also much shorter, and not 

 much longer than the scales. 



A small, handsome tree, growing from 30 to 40 feet high, with 

 horizontal branches and straight branchlets, little forked, found on the 

 Real del Monte Mountains in Mexico, at an elevation of from 8,000 

 to 9,000 feet, and in the Oregon country.

This monoecious genus has been named by Carriere after Mons. 

 Keteleer, at that time one of the firm of Thibaut and Keteleer, at 

 Sceaux. 



Large evergreen trees with, when old, umbrella-formed crowns. 



The leaves are almost two-ranked, and more or less scattered, stiff, 

 linear, flat, a little curved near the base, long and sometimes pointed, 

 green on the upper side, and a lighter green on the under side. 



The cones are upright and cylindrical. In some descriptions we are 

 told that the scales keep together, but I have observed that in my 

 collection they usually droop like the cones of the Abies. 



Much difference of opinion exists as to whether Keteleeria For- 

 tunei is a Spruce, a Silver Fir, or a new genus, which arises from its 

 having erect, cylindrical cones with persistent scales, soft angular 

 seeds full of turpentine, permanent wings, and flat, linear-lanceolate 

 leaves somewhat spirally arranged on the young shoots, and more or 

 less two-rowed on the adult parts ; from all of which it would seem to 

 be intermediate between the two ; but having persistent scales on the 

 cones, it must be considered as belonging to the Spruces rather than 

 to the Silver Firs (G. Gordon, " The Pinetum," 1875).
