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

Infrequent throughout the state. It is usually found in moist, sandy soil along streams, about ponds, in old logging roads, and along moist roadsides. Panicum Tuckermani Fern. is a closely allied species which I am not able to separate from Panicum Gattingeri. Some of my specimens have been named for me as Panicum Tuckermani, but I am referring them to Panicum Gattingeri until satisfactory characters are found to separate them.
