 Flat-top Aster. Map 2063. Infrequent to somewhat frequent in marshes 

 and low places in woodland and in moist, prairie habitats throughout the 

 lake area. It is also found in a few of our southern counties in low, flat

 almost hirsute but none of our plants have leaves that are puberulent 

 beneath.
