Low hills, usually in pine woods, 5 to 100 feet : along the coast from San Mateo 

 Co. to Monterey Co. Apr. -June. 



Field note. — This narrow endemic has been rarely collected. The two known stations are in 

 San Mateo Co. (Moss Beach, K. Brandegee) and in Monterey Co. On June 5, 1932, it was found 

 growing luxuriantly in an opening in the Monterey Pine forest at Pacific Grove (Crum 1406) 

 where the plants trailed do^vn a streamlet and attained their best development in the marshy soU 

 of a miniature flood plain. On higher ground under the pines, where the soil was dry, a few 

 stunted specimens were seen. The plants were blooming profusely, the corollas bright golden 

 yellow, varying considerably in size on the same individual.
