From Flora of Indiana (1940) by Charles C. Deam

         In a hard, white, minimacid, clay soil in a post and pin oak flat in Spencer County about 4 miles northwest of Chrisney. It was abundant in a 40-acre fallow field and scattered in an adjoining open woods, but was not found in the thick woods. Whether it was introduced into the fallow field and spread into the adjacent woods, or vice versa, I do not know.
