WESTERN FOREST TREES 



The western division of trees of the United States, including the 

 Rocky Mountain and Pacific coast forest regions (fig 7), has a total of 

 227 native tree species, representing 76 genera, 33 families, and the 2 

 broad classes which embrace all trees. 12 Popularly the different spe- 

 cies are distributed as follows: 62 conifers, 2 yews (turnion), 1 palm, 

 5 yuccas, 4 cacti, 3 hawthorns, and 150 species of willows, alders, 

 poplars or cottonwoods, oaks, legumes (mesquites, beans, locusts, 

 etc.), myrtles, and other hardwoods or broadleaf trees. 



Seventeen of the above 227 tree species grow also in the eastern 

 division of trees and, therefore, are described under both regions. 

 These include the white spruce, dwarf juniper, aspen, balsam poplar 

 (Balm-of-Gilead), peachleaf and Bebbs willows, paper birch, coral- 

 bean, and buttonbush, which extend across the United States, and the 

 wild plum, pin cherry, honey mesquite, hoptree, leucaena, boxelder, 

 red or green ash, and nannyberry which extend westward into the 

 Rocky Mountains.
