Aster oblongifolius Nutt. 



6a. Aster sagittifolius var. urophyllus Lindl. White Arrow Aster. 

 Map 2039. This variety is infrequent to frequent in very sandy soil, 

 usually in open woodland and in the dunes. It is distinguished from the 

 species by its white rays, closer inflorescence, and the under surface of 

 the leaves, which is more glabrous than in the typical form. In fact, 

 the whole plant has a more glabrous aspect. 



N. Y. to Minn. 



7. Aster Drummondii Lindl. Drummond Aster. Map 2040. Very local 

 in dry, open woods. Reported from the Calumet District by Peattie. This 

 species seems to be merely a pubescent form of the preceding one but its 

 range does not coincide with that of A. sagittifolius. 



Ohio to Minn., southw. to Ky. and Tex. 



8. Aster undulatus L. Wavyleaf Aster. Map 2041. A rare aster 

 found on the crests of high, open ridges and on high, wooded banks. It 

 has been reported from five other counties besides those indicated on the 

 map, but I have seen no specimens to verify these reports. My experience 

 indicates that it is very local. 



N. B. to Ont. and Minn., southw. to Fla. and La. 



9. Aster novae-angliae L. New England Aster. Map 2042. This is 

 a species of moist, rich soil and is found throughout the state. It is fre- 

 quent to rather common in the northern part of the state, becoming infre- 

 quent or rare in the hill area of the southern part. It is more generally 

 found in marshy places, along moist roadsides, and in prairie habitats. 



Maine to Sask., southw. to S. C, Ala., and Kans. 



9a. Aster novae-angliae f. roseus (Desf.) Britt. This is a form with 

 rose colored rays. I have found it a few times, and I have also found a 

 white rayed form. 



10. Aster patens Ait. Spreading Aster. Map 2043. Local in the 

 southwestern part of the state on the crests of open, wooded ridges, usually 

 with black and white oak or in very sandy soil on wooded, sandy knolls,
