R. Carolina L. — (R. humilis Man. ed. 7; vid. Rhodora, 20: 91,

R. ciNNAMOMEA L. CiNNAMON RosE. — Persistent about old sites 

 and established along roadsides, particularly on the upland. 



R. GALLICA L. — An occasional roadside escape; Great Harrington;

R. palustris Marsh. Swamp Rose. — {R. Carolina Man. ed. 7 and 

 111. Fl. ed. 2; vid. Rhodora, 20: 91, 1918.)

R. setigera IVIichx. Climbing or Prairie Rose. — Two plants 

 in a thicket above the Housatonic River, Stockbridge. 



R. spinosissima L. Scotch Rose. — Roadside escape, New Marl- 

 boro. 



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.
