9G0 REPORT OF STATE GEOLOGIST. 



E. purpureum falcatum (Michx ) Britton. 



Probably found associated with the species throughout, its 

 range in the State. Definitely reported from Hamilton and Ma- 

 rion counties by Mr. G. W. Wilson. Many varietal forms of 

 equal distinctness might be established, as is this, upon leaf char- 

 acters, since purpureum is one of our most variable species. 



E. serotinum Michx. Late-flowering Thoroughwort. 



Found chiefly in the southern part of the State, having no 

 reported locality north of Tippecanoe County. Found in various 

 localities, but most abundant in gravelly banks; it is also found in 

 moist woodlands, though not in as great abundance. 



Flowers in August and September. 



Jefferson (J. M. Coulter); Monroe and Vigo (Blatchley); Put- 

 nam (MacDougal); Gibson and Posey (Schneck); Clark (Baird 

 and Taylor); Tippecanoe (Coulter); Daviess (Clements); Steuben 

 (Bradner). 



E. hyssopifolium L. Hyssop leaved Thoroughwort. 



In dry fields and fence rows. Reported from but one county. 



Flowers from August until September. 



Tippecanoe. 



E. altissimum L. Tall Thoroughwort. 



Occasional in a few counties of the State, growing in dry, rather 

 coarse soils. 



Flowers late in July. 



Tippecanoe (Conner and Laben); Dearborn (Collins); Clark 

 (Baird and Taylor); Franklin (Meyncke); Marion (Wilson); Gib- 

 son. 



E. sessili folium L. Upland or Bastard Boneset. 



Usually growing in dry woods, sometimes extending into the 

 opens. In Gibson and Posey it is found growing abundantly in 

 moist soils. Its range is such as to lead to the belief that it is 

 to be found in all parts of the State. 



V lowers July to September.
