io6 CONIFEROUS TREES 



of a lighter green, are scarcely i inch long, blunt, 

 thick, and rounded. The cones are remarkably 

 thin for their length, which is usually about 3 

 inches. Jepson, in his Silva of California, regard- 

 ing P. Breweriana, says that it varies a good deal 

 in height, for mature specimens are met with from 

 20 to 95 feet high, with a trunk diameter of from 

 6 inches to 3 J feet. A pecuHarity of this tree is 

 its pendent branchlets, which are said to hang 

 down from 2 to 4 feet. Young specimens do not, 

 however, exhibit much of this character. Nathaniel 

 Lord Britton, in his North American Trees, refers 

 to it as the rarest and probably most beautiful 

 of the American spruces. He also says that the 

 wood is of good quality, but, owing to the rarity 

 of the tree and its inaccessibility, it has not been 

 applied to any economic use. 



P. Engelmanni, Engelmann. (Synonyms : 

 Pinus commutata, Parlatore ; Abies Engelmannii, 

 Parry.) Rocky Mountains of Montana, Oregon, 

 south to Arizona. 1864. — This tree resembles the 

 Black Spruce of Eastern America, for which it 

 was mistaken by all botanical travellers in the 

 Rocky Mountains, until Dr. Parry detected its 

 specific distinctions, and dedicated it to the dis- 

 tinguished botanist whose name it bears. In this 

 country it forms a neat specimen of broadly conical 

 outline, the branches being stiff, and the long 

 foliage sharply pointed and dull green of colour. 

 The cones nearly resemble those of the better- 

 known P. sitchensis, and are about 2 inches 

 long. 



P. Engelmanni glauca is, in so far as orna- 

 mental properties are concerned, a far more desir-
