Figure 9. Chrysothanmus monocephalus Nelson and Kennedy 

 The genus Chrysothamnus and allied genera need revision 

 perhaps more than any other large group of western ji'ants. Un- 

 fortunately, they are of little or no foiage value, although cov- 

 ering large areas in the Great Basin region. 



This alpine species of Chiysothamnus which we here illus- 

 trate was described as new in 1906. It is a rigid shrub about a 

 foot high, with numerous short divaricate branches, sharp pointed 

 leaves and insignificant pale yellow flowers. It grows among 

 lava rocks on Mt. Rose, Washoe county, Nevada, at from loooo 

 to T0800 feet elevation.
