From Flora of Indiana (1940) by Charles C. Deam This plant is extremely rare in Indiana. The only recent specimens are from the low dunes near Lake Michigan in Lake and Porter Counties. It formerly was frequent on the low dunes at Pine, now the north end of Clark Street in Gary, but in 1935 search was made for it and only a few plants were seen. It will soon be extinct at this station, and only a few plants have been seen in Porter County. In the Wabash College herbarium are two sheets collected by Dr. A. Clapp Aug. 6, 1835, in the "barrens" (in Floyd or Harrison Counties). ...... Indiana Coefficient of Conservatism: C = 8 Wetland Indicator Status: FAC
