From Oregon to the Saskatchewan and southward in the mountains to the southern Sierra 

 Nevada and New Mexico ; frequent on the eastern slope of the Sierra, and reported by Muir as 

 forming dense thickets along the branches of the San Joaquin, King's and Kern Rivers at an alti- 

 tude of 6,000 to 7,000 feet. It is seldom large, usually 8 to 15 feet high. In the Atlantic States 

 it has the leaves much more densely pubescent and hoary, nearly resembling the typical form of 

 the Old World, or sometimes smoother and glaucous beneath. 



ORDER XCII. MYRICACE-E. 



Shrubs, monoecious or dioecious, with alternate usually waxy-dotted and fragrant 

 leaves, mostly without stipules, and flowers solitary and sessile in the axils of scaly 

 bracts of the axillary sessile ovoid or cylindrical aments ; perianth none ; stamens 2 

 to 1 6, sessile, or the filaments somewhat united ; ovary with 2 to 4 small scales or 

 bractlets at base, 1 -celled, 1-ovuled, with 2 sessile filiform stigmas ; nut small, drupe-
