nearly equally winged. The thin bark is bright cinnamon-

ROCKY MOUNTAIN JUNIPER 



Junipcnis scopulorum. Pine Family 



A tree ten to fifty feet high. Leaves: opposite in pairs, spiney-topped, 

 closely appressed, imbricated, four-ranked, acute. Fruit: berry-like 

 cones, glaucous, borne on straight peduncle-like branchlets. 



This is the Juniper Tree of the West, whose branches 

 appear quadrangular owing to the flattened manner in which 

 the four-ranked leaves grow on the twigs. The berry-like 

 cones are bright blue, sweet, and covered with a whitish 

 bloom. 



Jiiniperiis horizontalis, or Creeping Juniper, is a depressed, 

 and usually procumbent shrub, seldom growing more than 

 three feet high. Its leaves are similar to those of the Rocky 

 Mountain Juniper, and its fruit is a blue berry-like cone, 

 containing one to four seeds, whereas the preceding species 

 is only one to two seeded. 



Jiiniperus conininnis var. montana, or Alpine Juniper, is 

 a very depressed, almost prostrate species of Juniper, which 

 forms on the ground large circular patches that sometimes 

 extend to ten feet in diameter. It grows at extremely high 

 altitudes, and is one of the last signs of vegetation encoun- 

 tered near the tree-line. The leaves, which densely cover 

 the branches, are channelled, and sometimes whitened on the 

 surface ; they are set in verticils of three on the twigs. The 

 cones are berry-like, being rounded, smooth, and dark blue. 



HOARY WILLOW 



Salix Candida. Willow Family 



An erect shrub. Leaves: persistently white-tomentose beneath, green 

 and loosely tomentose above, oblong-lanceolate, thick, sparingly dentate
