From Flora of Indiana (1940) by Charles C. Deam
Infrequent in dry, sandy soil or in moist, prairie habitats in the lake area, mostly along roadsides and railroads, becoming rarer southward. In the southern part of the state it is found on washed slopes, sandy, wooded ridges, along roadsides in clay or on sand hills, and in the hard, clay flats. In 1935 I noted this species to be abundant in the old Beaver Lake bottom in Newton County.
