 throat, tapering at the base, 5-toothed, more than twice 

 as long as the pappus ; anthers surpassing the corolla, with 

 prominent free tips ; styles cylindrical, hairy, exserted be- 

 yond the stamens and apparently growing after the 

 anthers become empty; pappus scales 3 mm. long, ^ 

 mm. broad, corneus, linear-acuminate with fimbriate

This Grindelia is an extremely localized species. It 

 differs from typical Grindelia. in having entire leaves, 

 turbinate involucre and more numerous persistent pappus 

 bristles. The long, conspicuous styles give to the flower 

 its chief beauty, hence the name. It grew in the same 

 sandy waste as the equally local Psoralen juncea, and was 

 just coming into bloom July 13th. There were many 

 plants, but all specimens were from the only plant seen 

 in bloom. 



Type in the Herbarium of the California Academy of
