Solidago media (Greene) Bush 



26. Solidago media (Greene) Bush. Map 2030. This species prefers 

 the moist soil of prairie habitats and is found also about lakes and in the 

 southern part of the state in flat woods in a slightly acid soil. 



Ind. to Minn., southw. to Mo. 



27. Solidago remota (Greene) Friesner. Map 2031. This goldenrod 

 also prefers the moist soil of prairie habitats but is found also in dry sand 

 and in wet woods. Restricted mostly to northwestern Indiana. 



This and the preceding species are closely allied and in the extremes 

 are difficult to separate and both species may be considered only as varie- 

 ties of Solidago graminifolia. When the literature is considered it is ap- 

 parent that authors are far from unanimous concerning the status of the 

 species of the section Euthamia of the genus Solidago. I have made no 

 field study of the group and my conclusions have been drawn from the 

 literature and from my specimens. 



Ind. and Wis. 



8892. BOLTONIA L'Her. 



1. Boltonia asteroides (L.) L'Her. White Boltonia. Map 2032. In- 

 frequent in moist soil in prairie habitats along roadsides and streams 

 and about lakes, ponds, and sloughs. Rare or absent from the eastern 

 part of the state.
