From Flora of Indiana (1940) by Charles C. Deam
This is a woodland species well distributed throughout the state. It prefers a moist soil. Usually there are only a few plants growing at one place, but rarely it is found in dense or large colonies. [Deam's var. grimesii has glandular peduncles.] This variety is local but frequent in its habitat. It prefers a hard, white clay soil in pin oak, sweet gum, and river birch woods. It is easily distinguished in the field by its wide upper leaves.
