Forms have been collected in Lanesboro, Stockbridge and Sheffield 

 which appear to be hybrids between R. Carolina (R. humilis Man. ed. 

 7) and R. rubiginosa. 



In Sheffield and Egremont forms are frequent which must pass as 

 hybrids between R. Carolina (R. humilis Man. ed. 7) and R. palustris. 

 Other forms appear to be hybrids between R. blanda and R. palustris. 

 There is a great deal of variety among these forms, and the whole 

 material needs careful study.
