Patna ENGELMANNI AND PicEA pUNGENS. —In the Gardeners’ Chronicle of December 24, 1881, p. 828, I [145] 
notice a reference to the beautiful blue spruce of the Rocky Mountains, under the name of Picea Engelmanni. This 
is a mistake, which I have repeatedly met with. The spruce in question is my Picea pungens, formerly (but erro- 
neously) referred to P. Menziesii (= P. Sitchensis), of the Pacific coast. The true P. Engelmanni is a second distinct 
species of the same mountain region, but occupying higher elevations. It forms extensive forests at an altitude of from 
9,000 to 11,500 feet up to the timber line, and a scrub above it. It has pubescent reddish branchlets, square leaves 
less sharply pointed, and small cones ; its light cinnamon-brown bark is thin and scaly, and the leaves of young seed- 
lings are smooth-edged. Picea pungens has white glabrous branchlets, stouter, in old specimens somewhat flattened, 
spiny-pointed leaves, blue in young trees and in the young growth of old trees ; the cones are much longer and paler, 
the bark thick, cracked, and grayish ; leaves of seedlings somewhat denticulate. It never occurs in forests, but is scat- 
tered along the banks of mountain streams at lower elevations than the other. Old trees become bare and quite un- 
sightly, but the large pale cones in their tops are a very conspicuous feature. — [Jan. 4, 1882, n. s., vol. xvii-] 
TsuGA PaTronraANA AND HooKERIANA. — Perhaps you will permit me to venture a suggestion in reference to two 
other West American Conifers which have occasioned a good deal of doubt, discussion, and hypothesis, — I mean Abies, 
or properly Tsuga, Pattoniana, and Hookeriana, which are also mentioned in the same page of the Gardeners’ Chronicle. 
Prof. Sargent and myself have visited Jeffrey’s localities of Scott’s Mountain, in North California (not Oregon) and the 
mountains south of Fort Hope, on Frazer River in British Columbia, connected with the Mount Baker Range. In 
both localities (as in many others near the timber line in Oregon and California) the beautiful Tsuga now known every-
