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

Very local; in marshes and bogs. There are 18 reports of it from south of the lake area. I believe all of these reports should be referred to some other species although we now have two specimens from south of the lake area. One from Jefferson County and another which was collected by Wilson in Hamilton County in 1899 now in the herbarium of DePauw University. The books used by the early botanists did not enable them to easily separate this species from those closely allied to it, and that fact may have been responsible for some of the early reports.
