Common names have little more than local significance; the 
same plant may be known by many different names, and the 
same name applied to many different plants. We have at¬ 
tempted to use the names applied in the sections in which these 
plants occur. Other equally good names could have been used. 
The word “ sage ” is generally applied in the desert region to 
any plant with light-colored foliage. Sage and sagebrush are 
often used for plants which should more properly be called 
saltbush.
