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

Local in the southwestern part of the state on the crests of open, wooded ridges, usually with black and white oak or in very sandy soil on wooded, sandy knolls and terraces. None of my specimens have the pedicels, small branches, or small leaves of the branches glandular. The inflorescences vary from those with the branches terminating in a single head to those with 20-25 heads. The leaves are also variable. In one specimen the leaves are narrowed at the base into a margined, clasping petiole.
