148 Mr. DovGras on a new Species 
branches to the ground, when standing far apart or solitary. 
Some few I have measured 140 feet in length, but never E. 
larger in circumference than that just cited. 
The largest and most handsome trees inhabit the alluvial 
deposits on the western flanks of the Cordilleras of New Al- 
bion, at a very great elevation above the level of the sea, being 
1600 feet below the range of perpetual snow in the parallel of 
40? N. On the less elevated mountains near the coast, where 
the temperature is higher but more uniform, in the parallel of 
37° N. in decomposed granite, schist, or gravelly soils, the 
trees are smaller and fewer, inhabiting the summit of the moun- 
tains only. 
The wood is white, soft, coarse-grained, and, I think, not very 
durable. A copious transparent resin issues from the wounds. 
Leaves in threes, very rarely in fours, 11 to 14 inches long, con- 
vex and smooth on the underside, channelled above, with an 
elevated ridge, pointed, and furnished at the margin with mi- 
nute teeth, which become more distant and conspicuous towards 
the extremity ; erect in summer; flaccid and drooping during 
winter. Sheath 1:5 inch long, light brown, chaffy, and torn at 
the top. Stipule lanceolate, rigid. Male and female catkins erect. 
Cone (which abounds in pellucid resin) ovate, recurved, pressing 
on the branch for support, 3 to 9 in number, surrounding the 
same stem, persistent, and remaining on the tree for a series of 
years, like P. Banksiana; 9 to 11 inches long, 16 to 18 inches 
round. Scales spathulate, 2:25 inches long, having a very strong, 
sharp, incurved point, which near the base exceeds the length 
. ofthe scale. Seed somewhat oblong, tapering to the base, flattish 
on the inside, :875 inch long, nearly :500 inch broad. Shell 
thick, hard, brown. Wing short, stiff, one fourth the length of the 
seed, which it nearly encompasses. Kernel pleasant. Coty yledons 
7—12 in number.
