Tiny wildflowers: June centaury

Each flower is less than 1 cm wide (about 1/3 inch).

 

Thanks to J. Maughn for identifying this as Muhlenberg's centaury (zeltnera muehlenbergii), also called June centaury, a wildflower native to Western North America. A 1993 plant survey lists it as growing at Jasper Ridge.
