THE FRUIT: achenes; pappus brown or white. 



Many of the plants of the Commons are stiff, even if 

 they are low growing, and the White-topped Aster is no ex- 

 ception. On the ground under the pine trees and practically 

 everywhere on the Commons are flat rosettes of spatulate 

 leaves, from which rise somewhat leafy stems, topped 

 with large, much branched clusters of what appear to be 

 small flowers of a pinkish .cast. If these flower heads are 

 examined more closely, they are found to be a circle of 

 rays set within an outer circle, and under the strong lens 

 of the microscope, tiny flowers can be discerned.
