This species has been reported from the dune area, Lower Wabash Valley, and from Parke, St. Joseph, Steuben, and Vigo Counties. I have seen the Parke County specimen and it should be referred to Hieracium Gronovii. This hawkweed is a weed in sandy fallow fields in the vicinity of Heaton Lake, Elkhart County, and in several fields in northeastern St. Joseph County. It is probably more widely distributed. I noted it as frequent in the old Beaver Lake Basin about 3 miles south of Lake Village, Newton County.
