From Flora of Indiana (1940) by Charles C. Deam
The only record from Indiana is that of a specimen collected July 3, 1888, in dry ground near Crown Point, Lake County, by Dr. M. A. Brannon. This specimen came into the hands of S. C. Wadmond of Delavan, Wisconsin, who was generous enough to donate it to me. This species is either very rare or not recognized by collectors.
