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

Frequent to infrequent in wet woods throughout the state. There is a form common in a low, wet woods in section 17 of Point Township, Posey County, that has the fruit more or less hispid. I studied this plant where it was common over several acres and found the fruit to be very variable. There were plants with all of the fruit glabrous, plants with some of the fruit more or less glabrous, and some plants with all of the fruit rather densely pubescent.
