From Flora of Indiana (1940) by Charles C. Deam
This species is easily recognized in the field but herbarium material is difficult to determine. I have seen it growing in Posey County. I have herbarium material from Decatur County which I believe belongs here. In Posey County it grows in hard, white clay soil in low, open woodland with pin oak.
