 No. 7967, collected June 5, along the Sacramento a short 

 distance below Shasta Springs, Siskiyou county, growing on the 

 edge of a cold mountain stream, the shrub about four feet high, 

 widely spreading. It was also noticed within the inclosure at 

 Shasta Springs, along the trail leading to the hotel. The speci-

 but differed from 7967 in no respect except in less spreading 

 o^rowth.
