Local in northern Indiana on open sand hills and dunes and near Lake Michigan on dry interdunal flats. It was reported by Schneck as rare in prairies in the Lower Wabash Valley but since the Indiana side of the Wabash River has no real prairies in the territory where Dr. Schneck collected, I believe that his report should go to the Illinois side of the river.
