I have never seen an Indiana specimen of this plant, but it 

 doubtless occurs, at least in the northern tier of counties. A ref- 

 erence of this form to Marion County, no collector's name being 

 given, is doubtless an error. The range of the plant is toward 

 the north, and our northern counties represent pretty fairly the 

 southern limit of the form. The. range as given in Britton and 

 Brown (Vol. 2, p. 542) specifically includes Indiana, an inclusion 

 probably based upon the work of E. J. Hill.
