70 Rydberg: Notes on Rosaceae — XIV 



Others have suggested R. blanda Ait., but the true R. blanda is 

 a boreal plant and not found on the Missouri, and the leaves 

 are dull and pubescent beneath. The R. Woodsii of the Botanical 

 Register might sooner be a form of that species. The only 

 species that agrees with the description of the original R. Woodsii 

 is the one that Torrey called R.foliosa leicocarpa and in my flora 

 of Colorado I called R. Macounii, the same as Greene has des- 

 cribed as R. Sandbergii and Lunell as R. deserta. I also think 

 R. fimbriatula Greene belongs here. It is a shrub belonging to 

 the Rocky Mountain region but extends eastward to the Missouri 

 River. Watson referred it partly to R. Woodsii, partly to R. 

 Fendleri. Watson assigned also new characters to R. Woodsii, 

 viz. lobed sepals. Notice that Lindley originally described them 

 as "entire." The lobing or not-lobing of the sepals is a character 

 of no value in the Cinnamomea group. In other groups as for 

 instance, the Carolina and Canina groups, it is a fairly 

 reliable character. Rosa Maximiiliani Nees belongs to this 

 species. 



North Dakota: Pleasant Lake, Benson County, 1912, 

 Lunell (R. deserta Lunell); Little Missouri River, Moyer 702.

23. Rosa terrens Lunell 

 This species differs from all the species of the Cinnamomiae 

 of eastern North America in the stout prickles especially on 

 the shoots. The prickles are fully as stout as those of the sweet 

 brier. It is only known from the type collection. 



24. Rosa Macounii Greene 

 It has been shown that the pubescent plant illustrated by 

 Lindley in the Botanical Register under the name R. Woodsii 

 has had a very confused nomenclatorial history. Watson 

 thought it was the original R. Woodsii and stated that it was 

 the same as R. Maximiliani Nees. At the time when I noticed 

 the discrepancy in Lindley 's treatments, I thought that Watson 's 

 statement was correct and adopted the name R. Maximiliani 

 for the present species. The name was used in that sense in my
