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

This variety was reported from Kosciusko County by Chipman (Proc. Indiana Acad. Sci. 1896: 155. 1897). He says that he found two specimens and that these were sent to William Trelease, who had recently monographed the genus, and that Trelease reported that they were this species. It was also reported from Kosciusko County by Clark, and from Lake County by Pepoon and by Peattie. I found this variety to be abundant in a springy place at the base of the south bank of the southeast side of Lake Pleasant about 4 miles northeast of Orland, Steuben County. Some of the mature plants were up to 3 feet high.
