From Flora of Indiana (1940) by Charles C. Deam
This is a very rare plant in Indiana and I have specimens from only three places. I have a specimen collected by Umbach on May 14, 1898, in full flower in a swamp near Miller, Lake County. I have another specimen discovered by M. W. Lyon, Jr., and Mrs. Lyon in a tamarack bog near Dune Park, Porter County. In 1935 I collected a specimen discovered by R. M. Tryon, Jr., in a decadent bog in the eastern part of Porter County. This species will probably reach extinction in Indiana before long.
