very much resemble the Cedar of Lebanon in habit, with dense far-spread-

 bight of 5 or 6 ft from the ground. Branches with dark gray and some- 

 what rugose bark; branchlets rather stout; Ivs bright green, aeutish, ob- 

 scurely pitted on the back, often with a longitudenal furrow on each side: 

 scales of very young cones with conspicuous foliaceous tips; mature cones 

 clustered on short, stout peduncles, oblong-ovate (1-1% i long by 9 li 

 broad), of 5 or usually 6 pairs of scales, with a broad thickish or on the
