1919] Hall-Goodspeed : Ruhher in West American Shruhs 271 



Haplopappus Palmeri Gray. 



In habit and general appearance this species is much like //. 

 ericoides except that the plants are usually smaller. It belongs to 

 southern California and is especially common on the plains and lower 

 footliills of the coastal slopes. It is absent from the sand dunes along 

 the coast. One sample (725) from Riverside was found to contain 

 0.91 per cent of rubber. Another (721), also from Riverside, and 

 one (201) from Colton were examined microscopically but no rubber 

 could be detected in either of them.
