The typical form of this species occurs west of the Cascade Mountains. The eastern 

 Washington forms are very variable as to leaf and fruit and consist perhaps, of two species. 

 Specimens have frequently been referred to as Rosafendleri Crepin, but it is not at all clear 

 how this is to be distinguished. 



Rosa californica Cham. & Schlecht, in typical form at least, seems not to reach 

 Washington. Specimens so referred are probably forms of R. pisocarpa.
