In 1881 Dr. Engelmann published it under the name of T. carO" 

 Unia7ia, described from specimens (collected by Professor Gibbs, 

 of Charleston), as distinguished from T. canadensis by its larger, 

 glossier, blunter leaves, and its larger cones with wide-spreading 

 scales. These points, combined with its alpine habit, seem quite 

 sufficient to indicate that the variation from a common type has 

 been long continued, and is sufficient for specific recognition (J. G. 

 Lemmon). 



In Denmark we have only a young plant put out for trial last 

 year.

Habitat. — Maximowicz found this Tsuga isolated here and there 

 on the mountains of Kiushiu ; Mayr saw it on several mountains of 

 Central Japan, such as the Nantasin, the Shiranesan (Kotsuke), in 

 large forests, some of these not containing other trees. It was often 

 found in the Beech region, and even a few examples were found near 

 the alpine region. 



Possibly hardy.

1855), and in Proc. Hort. Soc. ii. 202 (1863). Ahies Williamsoniiy

I find it right to keep the name T. Hookeriana to the young plants 

 we have received under that denomination, as they look different from 

 T. Pattoniana. / 



Hardy. 



This tree was found by Mr. W. Murray on Scots Mountain, one 

 of the high Californian mountains, about lat. 41° 20' N., long. 

 122° 37^ W., where the ground was already covered with snow, on 

 the IGth of October. Dr. Newberry found it on the summit of the 

 Cascade Mountains in Oregon, lat. 44° N., and says that it is the 

 most alpine in its habit of all the Firs, extending from the height 

 of 6,000 feet up to the limit of perpetual snow. He adds: "It 

 will doubtless be found in similar circumstances on other parts of 

 the Cascade range, but we saw it only on the group of mountains 

 called the Three Sisters." We are no grantors of propositions ; and 

 therefore, before assenting to it, should like to know, a little better 

 than appears from the Doctor's description, what he means by its being 

 the most alpine in its habit of all the Firs. Will it bear a more arctic 

 climate than Finns Banksiana, or Ahies nigra, or A. excelsa, which in 

 Norway extends as far north as lat. 70° 1 We think not ; but that is 

 of less consequence than the important fact that it is a beautiful tree, 

 and so far alpine as to make it perfectly safe to cultivate in the coldest 

 parts of Britain or temperate Europe. Lobb found it in great abun- 

 dance on the highest peaks of the Sierra Nevada, near the head-waters 

 of the north tributary of Feather River, also more southerly towjvrds
