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

Very rare. It is locally common, however, on the rocky open slope of the Ohio River about midway between Cannelton and Tell City. I saw it in Crawford County near Wyandotte Cave but I was not prepared to preserve a specimen. I have it from two places along the Ohio River above Cannelton in Perry County and from one place along the Ohio River about 3 miles above Mauckport in Harrison County. Charles M. Ek found a large colony in hard, clay soil along a railroad embankment a quarter of a mile north of Galveston, Cass County.
