Habitat in Oregon, in California boreali, in Columbia Britannica, et insula Vancouveri. 
A Hemlock Spruce, about 100 feet in height, and according to Mr Brown {op. cit. fiupra ) of dark ver¬ 
dure and graceful appearance. In the young plants the verdure is not dark. Branches long, flexible, and 
llender. Branchlets cylindrical, pendent at their extremity, villous, the pulvini very flightly prominent 
[figs. 1 and 2]. Leaves [figs. 3 and 4] green, glaucous beneath, irregular in fize, 
from one-third to three-fourths of an inch in length, and about three-quarters 
of a line in breadth, folitary, growing fpirally round the branch, but difpofed 
fomewhat alternately, flat, flightly canaliculate on the upper fide, with a midrib 
on the under fide; ufually obtufely pointed, and not emarginate at the apex, 
petiolate at the bafe; above [fig. 5], without ftomata, below [fig. 6], with five to 
feven rows of ftomata clofe on each fide of the midrib, clothed with a filvery pul- 
verefcence, leaving a broad margin without ftomata. In its young ftate, the edge 
of the leaf has a tendency to fer-

Cones [fig. 7] about an inch in length, pale brown 
(according to Brown, numerous, terminal, and pen¬ 
dent), oblong ovate, narrow, with fix rows of fcales, 
about five in each row, fpirally arranged. Scales pale brown at the apex, deepening into purple brown at 
the bafe, loofely imbricated; the middle fcales about feven lines long, narrow oblong, flightly concave; 
thofe at the apex narrower than those in the middle, and thofe at 
the bafe fmaller and broader, fometimes roundifh [figs. 8, 9, and 
10, middle fcales, and fig. 11, bafal fcale]; the expofed part of the % 
fcale fmall, about one-third of its length, fomewhat fhining, and Fig ' 8 ' 
with roughly marked longitudinal ftriations, which have a tendency to radiate outwards ; the portion 
which has been covered is unequal on each fide, pubefcent, lefs ftriated, margin entire, irregularly 
lounded, and ufually flightly abraded. Bracts [fig. 12] purplifh brown, cuneiform, ciliated, from 
three-quarters of a line to one line in length, clofely adpreffed to the fcale. Mr Brown fays that- 
they aie three-lobed. This is not confiftent with our obfervation, but it is poffible that, when frefh, 
the lobes may be difcernible. As this is the only point in Mr Brown’s defcription which does not
