and dark yellow centers, and contrast rather prettily with 

 the pale foliage. In Yosemite this grows on rocky ledges 

 below five thousand feet and blooms late. It is common 

 from Monterey to Santa Barbara, blooming at almost all 

 seasons, and is very variable. 



These flowers do not look much like 

 Psildstrophe tlaose of a composite, but give more the

 clusters of lemon-yellow flowers. They 

 are each about three-quarters of an inch across, delicately
