 Mn 3:116. Adapted for roverin- dry slopes and barren 

 places. According to E. L. Greene, the true /,- | ,/. 

 sana is restricted to Colorado and perhaps New Mexico 

 while the form common j,, the re-ions north and west 

 of these localities is a different species, for which he 

 proposes the name R. pratincola; this form is .lescril.ed 

 above. The true R. Arkansana, Porter, differs l,v its 

 glabrous foliage, glandular and bristly stipules and re- 

 flexed sepals. At the same place (Pittonia, 4:10-14) 

 Greene describes four other new species belonging to 

 this section.
