Rhododendron occidentale Gray, Bot. Cal. 1: 458. 1876. 



No. 7948, collected June i, along the Sacramento opposite 

 Upper Soda Spring, Siskiyou county, in moist thickets. It is 

 common along the upper Sacramento in moist places from Pit 

 river north. The species occurs almost throughout the State, 

 and was first detected in the Bay region by Douglas. Hartweg 

 next collected it "in uliginosis prope Santa Cruz," but these 

 early specimens were referred to the eastern Azalea calendulacea.

 No. 7872, collected May 27, in thickets near the railroad a 

 short distance above Redding, Shasta county, growing in com-

 small shrub six or seven feet high.

 No. 7853, collected May 25, a short distance above Red-
