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

Our only specimens were collected by Nieuwland in Studebaker's woods, St. Joseph County. One specimen was collected June 4, 1912, and another was collected July 17, 1919. This cornsalad was reported in 1895 from Hamilton and Marion Counties by Wilson but I have not seen specimens to confirm this report.
