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

Frequent but never common throughout the state. It prefers a rather sandy or gravelly soil and is restricted to the wooded slopes and high banks of streams. The leaves of this species are variable and one form has been named. I am including it under the species.
