Liatris Bebbiana Rydb 



Jasper, Marshall, St. Joseph, and Vigo Counties and Schneck reported 

 it from the Lower Wabash Valley. Doubtless all of these reports should 

 go to this species. A specimen in the herbarium of Purdue University 

 collected in St. Joseph County by Barnes and labeled L. pycnostachya 

 is L. Bebbiana. I have seen the Jasper County specimen and it belongs 

 here. Blatchley reported it from Vigo County. He collected his speci- 

 men in the Haeckland Prairie in 1889 and it is now in the herbarium 

 of Butler University. I collected my specimen in the same place in 1917. 

 Since the Lower Wabash Valley has no prairies on the Indiana side of the 

 river where Dr. Schneck collected, it is best to refer his specimen to Illinois.

4. Liatris spicata (L.) Willd. (Lacinaria spicata (L.) Ktze.) Spike 

 Gayfeather. Map 1998. This species and others of this genus are often 

 called blazing star. In the northern half of the state this species grows 

 generally in marshy places and in moist prairies. In the prairies it is often 

 so abundant that it gives a rose purple color to the landscape. In the 

 southern part of the state it is local and is found in the "flats" and in sandy 

 soil on open, wooded slopes. 



The rachis of all of my plants is quite glabrous. Kriebel's no. 3958 from 

 Greene County has the rachis closely puberulent.

5. Liatris scariosa (L.) Willd. {Lacinaria scariosa (L.) Hill., Laci- 

 naria Deamii Lunell, Lacinaria scariosa intermedia Lunell, Lacinaria 

 scariosa var. Nieuwlandii Lunell, Lacinaria scariosa var. petiolata Lunell, 

 Lacinana scariosa var. praesignis Lunell, and Lacinaria scariosa var. 

 strictissima Lunell.) Map 1999. Lunell in his revision of the genus de- 

 scribed new species and new varieties and cited Indiana specimens in the 

 Deam Herbarium. I am regarding this polymorphic species as a complex.
