JUNIPERUS SCOPULORUM (Sargent). 



Garden ami Forest, Vol. X. p. 420, fig. 54 (1897). 



Trees of Great Britain and Ireland, Vol. VL p. 1486 (1912). 



A tree about 40 feet high and 9 feet in girth, often divided near the 

 base into several stems. Adult foliage very similar to ./. virg in i ana, 

 but with stouter branchlets and leaves marked on the back by a 

 conspicuous glandular pit. Fruit ripening in the second year, 

 globose, } inch in diameter, light blue, glaucous. Seeds two, tri- 

 quetrous, reddish brown, prominently angled, with a longitudinal 

 groove. 



This juniper was formerly regarded as the western form of 

 J. virginiana, but is now considered by American botanists to be 

 a distinct species. It differs from J. virginiana in the slightly 

 larger fruits, which ripen in the second year. 



Jimiperus scopulorum grows on dry rocky ridges, and except 

 near the coast, usually at over 5,000 feet elevation, from the eastern 

 foothills of the Rocky Mountains from Alberta to Texas, westward 

 to the coast of British Columbia on Vancouver Island, and in 

 Washington, and to Eastern Oregon, Nevada and Northern Arizona. 

 It is probably the tree which is occasionally cultivated as J. fra- 

 y rails, a name which appears in Knight and Perry, Syn. Conif. p. 

 13 (1850). 



The illustration is from a photograph sent by Prof. Sargent from 

 the Arnold Arboretum.
