68 Rydberg: Notes on Rosaceae — XIV 



Minnesota: Duluth, Rydberg 8004; St. Louis River, 

 Carlton County, Sandberg 130; Two Harbors, E. P. Sheldon. 



19. Rosa blanda Ait. 



This species is confined within the region to the hardwood 

 groves in the northern part. I can see no difference between 

 the specimens from North Dakota, on which R. gratiosa Lunell 

 was based, and those from the Eastern States. 



Minnesota: Lake Minnetonka, Sandberg, 798, Thompson, 

 Carlton County, Sandberg 397; Minneapolis, 1895, E. P. Sheldon; 

 Lake Itasca, G. B. Alton. 



North Dakota: near St. John, Rolette County, 1912, 

 Lunell (R. gratiosa); Pleasant Lake, Benson County, 1912, 

 Lunell; Turtle Mountains, 1912, Lunell; Bottineau, 1890, Waldron. 



Manitoba: Oak River, Macoun & Herriot 70937; six miles 

 east of Forest, Macoun & Herriot 70940. 



20. Rosa subblanda Rydberg 



It is questionable if this species should be included among 

 the prairie roses, as the following specimens are referred to it 

 with considerable doubt. 



Iowa: Grinell, 1877, M. E. Jones. 



21. Rosa Fendleri Crepin 



This species is related to R. Woodsii and often confused 

 with it. It is distinguished by the glandular stipules, petioles, 

 and leaf-rachis. Watson distinguished it from R. Woodsii by 

 the entire instead of lobed sepals. In both species they are 

 either entire or lobed. R. neomexiana, R. arizonica, R. puberu- 

 lenta and R. granulifera have been confused with it, but these 

 all have curved prickles, while in R. Fendleri they are longer 

 and more slender, straight or nearly so. R. Fendleri is a common 

 species in the Rockies, ranging from Montana to northern 

 Mexico. It extends eastward also into the plains and prairies 

 and was redescribed from North Dakota by Lunell as R. poetica. 



Minnesota: Montevideo, Moyer 581. 



North Dakota: Bismark, 1912, Lunell. 



South Dakota: Hermosa, Rydberg 677. 



Nebraska: McCalligan Canon, Deuel County, Rydberg 100.
