Rosa Carolina L. 



not as common as the variety and does not extend as far north, becoming 

 very rare in the northern counties. I do not find where the range of this 

 species has been determined so I am forced to give the range as found in 

 our manuals. 



N. Y. to Kans., southw. to Fla. 



la. Rosa setigera var. tomentosa T. & G. (Rosa rubifolia R. Br. of 

 North Amer. Flora 22: 491. 1918.) Map 1174. This variety is distinguished 

 from the species by having the entire lower surface of the leaflets soft- 

 pubescent and the upper surface dull. It is more frequent than the species 

 and in some clearings it is often so abundant as to give them the appear- 

 ance of rose gardens. The species and variety are found in open woodland, 

 clearings, and pastures and along fences and roadsides. 



Ont. to Wis., southw. to Ga. and Tex. 



2. Rosa rubiginosa L. Sweetbrier. Map 1175. This rose is much 

 cultivated and it has escaped in all parts of the state. 



Nat. of Eu. ; N. S. to Ont. and Mich., southw. to Ga., Miss., and Kans. 



3. Rosa micrantha Borrer. Smallflower Sweetbrier. I found a 

 small colony of this rose along the roadside in Elkhart County where it 

 had persisted, no doubt, near the site of a former habitation, although there 

 was no evidence that a habitation ever existed here. Miss Edna Banta 

 writes me that she has known it for ten years as an escape in Jefferson 

 County. She says it is more or less frequent on the slope of the bluff of 

 the Ohio River from Madison to Greasy Hollow, a few miles east of 

 Madison. 



Nat. of Eu. ; sparingly escaped throughout the U. S. 



4. Rosa palustris Marsh. (Rosa Carolina L. of Gray, Man., ed. 7 and 

 Britton and Brown, Illus. Flora, ed. 2.) Swamp Rose. Map 1176. This 

 species is frequent to infrequent throughout the state, being more common
