While our Sierran plant, at least in so far as it has come to my 

 notice, appears to differ from S. Tolmiei T. and G. of Washington and 

 northern Oregon in the longer and narrower leaves with the stems 

 firmer and more lignescent, nevertheless certain collections made in 

 Oregon certainly go far to break down the distinctions between these 

 species (cf. Cusick 2985 from Crater Lake and T. Howell 320 from 

 Mt. Hood).
