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

I found this species in a wet prairie in Benton County about a mile southwest of Fowler. It was first found by Elmore Barce who told me where to look for it. It was found in Lake County by H. C. Benke. Pennell reports a specimen of this species in the herbarium of the Academy of Natural Sciences of Phil. adelphia, which was collected by Dr. Short in the "barrens" of Indiana. There is a specimen in the herbarium of Wabash College collected by A. Clapp in the vicinity of New Albany, Floyd County, in 1837.
