NOTES ON THE WEST AMERICAN CONIFERE 49 
of the larger dimensions given, but all have the whitish, 
corky bark described. It was related to us at Flagstaff that 
Mr. Merriam of the Death Valley Expedition, last season 
detected a spruce with corky bark on Mt. Kendrick. This is 
doubtless, the same tree. 
Variety elongata, var. nov. 
Another marked variety of Douglas Spruce with compara- 
tively thin, whitish (outside), shallow-furrowed bark, and 
conspicuous long, narrow, yellowish shining cones, 34-44 
inches long and one-fifth as thick, with comparatively short 
bracts and thin, soft scales, inhabits the great forest around 
the base of Mt. Hood, Oregon, where we detected it Sept., 
1892. This variety is in striking contrast with the usual 
short-fruited Douglas Spruce met with in the vicinity at 
lower stations. 
This long-coned spruce is not to be confounded with the 
“Big-cone Spruce’—Pseudotsuga macrocarpa (Torrey), 
Lemmon—of the San Bernardino Mts., Cal. That species is 
expressed by trees which are much less symmetrical than the 
well-known Douglas Spruce, they are found equally de- 
veloped from the bottom to the top of the mountains, the 
limbs are longer than the typical, inclined to be horizontal, 
the dark bark deeply furrowed, the ovate-elliptical cones very 
large, 5-8 inches long and one-fourth as thick, their convex 
seales at length firm, the lunate apophyses with a thin 
crenulate cartilaginous margin; bracts large but comparatively 
short, etc.; these very distinguishing characters never found 
shading off into any forms of the other well-known species— 
P. taxifolia. 
2. Spruce versus Fir. 
It is surprising that certain writers continue to use the 
name ‘Douglas Fir” when referring to Douglas Spruce. 
Most modern authors are at accord in restricting the use of 
Fir in a general way to trees of the very natural and com-
