Aster laevfs L. 



and terraces. None of my specimens have the pedicels, small branches, 

 or small leaves of the branches glandular. The inflorescences vary from 

 those with the branches terminating in a single head to those with 20-25 

 heads. The leaves are also variable. In one specimen the leaves are nar- 

 rowed at the base into a margined, clasping petiole.

11. Aster oblongifolius Nutt. Oblong-leaf Aster. Map 2044. Found 

 on high, wooded bluffs of the Ohio River. A report from Clark County is, no 

 doubt, correct. It has also been reported from Noble and Wayne Counties 

 but these reports doubtless are based upon wrong determinations. The re- 

 port from Tippecanoe County should be referred to the variety. 



Bluffs and prairies from Pa. to Minn., N. Dak., and Colo., southw. to 

 Va. and Tex. 



11a. Aster oblongifolius var. rigidulus Gray. Map 2045. I found this 

 variety on the high, gravelly slope of the flood plain of Big Wea Creek 

 about 4 miles southwest of Lafayette. Associated with it were other 

 western plants such as Muhlenber^gia cuspidata, Linum sulcatum, Litho- 

 spermum incisum, and Houstonia angustifolia. No doubt the Tippecanoe 

 County report for the species was made from a specimen collected in this 

 vicinity and should be referred to this variety. 



Ind., Wis., S. Dak. to Colo., southw. to Tex. 



12. Aster prenanthoides Muhl. Crooked-stem Aster. Map 2046. In- 

 frequent on wooded flood plains and in roadside ditches in a few counties 

 of the southeastern part of the state. It has been reported from a few of 

 the central counties and no doubt its range will be extended in Indiana, 

 although I believe it is a rare species in the state. 



Mass. to Minn., southw. to Va., Ky., and Iowa. 



13. Aster laevis L. Smooth Aster. Map 2047. Infrequent to rare in 

 all parts of the state. It is generally found on white and black oak ridges 

 and on bluffs of streams, in clayey soil or more often in very sandy soil.
