This is the largest tree of the New ]\Iexican mountains, in favoraI)le situations over 

 60 meters high, with a trunk 2 meters or more in diameter. The bark is rough and 

 dark-colored; the short (25 mm. or less) and obtuse leaves are arranged like those 

 of the balsam fir. It may be most easily recognized by the cones, which are rela- 

 tively small, composed of persistent thin scales, with the 3-parted bracts protrud- 

 ing a centimeter or more from beneath each scale. The tree occurs iii mixed forests 

 with yellow pine and" the true spruces, at elevations ranging from 2,250 to 3,150 

 meters, sometimes reaching timber line. In the northern part of the State it often 

 forms extensive pure stands in which there is little or no other vegetation. The 

 lumber is of good quality. In cultivation the Douglas spruce makes an excellent 

 decorative tree.

Low trees or shrubs with much imbricated, short, scalelike or awllike leaves; conea
