This very beautiful tree is closely allied to A. Canadensis, but may readily be distinguished by its much larger foliage. It grows about seventy to eighty feet high, with spreading, pendulous branches. Those who know and admire our common Hemlock (and who does not?) will be delighted with this exquisite tree. It may be asked, Is this tree hardy? In England, to my own knowledge, it suffers from cold; but this, I think, is more owing to the want of ripeness of the wood in the fall than to the degree of cold ; here, with us, the wood will be more thoroughly matured, and it will stand more cold; and should it require a slight protection while young, what lover of trees will refuse it? Major E. Madden* says of it: "Dr. Hooker has recently found it in Sikhim, forming a narrow belt of 1,000 feet, confined to very narrow gorges between 9,000 and 10,000 feet, on the immediate (south) flanks of Eunchinjinga, probably the loftiest peak in the world, being about 28,000 feet In the innermost valleys the limits are 8,500 and 10,500. The Gorkhalee name is "Thingta," or "Tingoorisulla ;" the Bhotiya, "Semadoong." Dr. Hooker considers it to be by far the most beautiful of Sikhim pines, whether as an individual tree, in groups, or in forest masses.
One specimen was twenty-seven feet in girth at the height of five fieet" It is also indigenous to other parts of the Himalayas, and found on pretty high elevations.
