SOME MINNESOTA ROSES. 



By Lycurgus R. Moyer. 



WHILE at Big Stone Lake last summer I collected what 

 seemed to be Rosa Woodsii Lindl. on both sides of the 

 State line, some in South Dakota and some in Minnesota. On 

 comparing the specimens with the collections of the botanical 

 survey in the herbarium of the State University at Minneapo- 

 lis I found that they had no Minnesota specimens. There is 

 a record in the supplement to Upham's Flora, page 47, that 

 this rose had been collected by Miss Butler "near Minneapo- 

 lis." The Manuals have long given the range of this species 

 as "from Minn. & Mo. to Colo." E. L. Morris, now curator 

 of the Brooklyn Museum, visited this place some years ago, 

 and we collected a rose on the granite ledges two miles north 

 of Montevideo which he was unable to name. It seems to be 

 this same species. 



But whether these collections are the true Rosa Woodsii 

 may still be an open question. These Minnesota collections 

 differ very little if at all from the rose collected by Heller in 

 New Mexico and distributed as Rosa Fendleri Crepin, and 

 marked "authentic specimen from the type locality;" and 

 they seem to be very near to Rosa Fendleri as collected by 

 Geo. E. Osterhout at Glenwood Springs, Colorado. Dr. Ryd- 

 berg in liis "Flora of Colorado" is uncertain as to whether 

 Rosa Woodsii occurs in Colorado at all, and gives the range 

 of Rosa Fendleri as "in valleys and along streams from S. D. 

 and Mont, to New Mexico and Arizona." Some of the roses 

 collected by me on the Missouri River in the vicinity of Mo- 

 bridge, S. D., closely resemble Heller's New Mexico specimen. 

 Can it be possible that Rosa Fendleri extends clear through to 

 Minnesota ? 



The beautiful roses growing on the banks of the Sas- 

 katchewan River at Medecine Hat, Alberta, seem to be the 

 true Rosa Woodsii in its thrifty form, while some of the Mis-
