P. CENTUANTHERA, Gray in Bot. Mex. Bound. 120, is a somewhat similar, but more peculiar, 

 nearly stemless species, with once pinnatifid leaves, longer and purnlo corolla, and awned anthers. 

 It was discovered in New Mexico, but hns recently boon detected in tho southwestern part of 

 Utah, so that it may reach the borders of California.
