Notes on Rosaceae — XIV 



Per Axel Rydberg 



Roses of the Prairies and Plains 

 The area here treated comprises the states between the 

 Mississippi River and the Rockies and north of Oklahoma, with 

 the exception of Missouri, in which so many southern plants 

 are found and in which the Ozark Mountains have a different 

 flora from the plains. As a key to the groups has already been 

 published in a preceding paper,* I shall here omit the same, 

 and I shall omit also the general discussion of any species 

 already treated there, only citing specimens collected in the 

 region now under consideration.
