 Mn. 3:116.— Adapted for covering dry slopes and barren 

 places. According to E. L. Greene, the true B.Arkan- 

 satia is restricted to Colorado and perhaps New Mexico, 

 while the form common in the regions north and west 

 of these localities is a different species, for which he 

 proposes the name B. prafineola; this form is described 

 above. The true B. Arkansana, Porter, differs by 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.

 lar to oblong, 3^-1 in. long. May, June. Alaska to On-
