Abies Mertensiana, Lindley, tke Californian Hemlock Spruce. 



Syn. Abies Williamsonii, Bridges, not Newberry. 



A large tree, found abundantly in the Oregon country, with 

 a thin, dark-coloured bark, much divided by small longitudinal 

 fissures on the stems of old trees, but somewhat smooth on the 

 younger ones. 



It is quite hardy ; but the timber is soft, white, and difficult 

 to rive or split. 



Seeds of this Fir have been largely disposed of in London, by 

 Mr. Bridges, under the erroneous name of Abies Williainsonii, 

 and with an equally false statement that it was the same as that 

 described under that name by Dr. Newberry, in the 6th vol. 

 of the United States Reports of Explorations and Surveys from 

 the Mississippi River to the Pacific Ocean ; but which latter Fir 

 is a very different kind, and one identical with Abies Pattoni, 

 the Giant Fir of California, while that sold by Bridges under 

 the name of Abies Williamsonii is the same as Abies Merten- 

 siana, the Californian Hemlock Spruce, and called " Lucatzin " 

 by the Indians in Upper California and in the Oregon terri- 

 tory. 



Abies microsperma, Lindley, the Small-seeded Japan Spruce. 



Leaves, solitary, about one inch long, and three-quarters of a 

 line broad, more or less arranged on the upper side of the 

 branchlets ; linear, narrow, flattened, and terminating in a small 

 prickle, or somewhat blunt point ; bright green above, and 

 glaucous below. Cones, cylindrical, two and a quarter inches 

 long, and three-quarters of an inch in diameter, and as broad 

 at one end as the other ; scales, loose, rectangular, with the 

 apices toothed ; bracteas, very small, ovate, and terminating in 

 a spine or mucro. Seeds, pale, cinnamon-coloured, one line 

 long, with ovate wings two lines long, sometimes acutely notched 

 on the margins. 



A tree growing from 40 to 50 feet high, with the under side 

 of the foliage very glaucous ; found at Hakodadi and Youku-
