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

An extremely rare and local plant. I have specimens from the low woods about Little Cypress Swamp in Knox County as follows: It was first found by Schneck on May 16, 1896, when it was in fruit. He again found it in flower on April 20, 1903. Blatchley found it in flower April 23, 1903. I found it in fruit May 23, 1926, and in flower on April 19, 1927. I made a study of it on the ground and made the following notes: Length of corolla 4 mm, expanse of corolla 4 mm, light Wisteria Violet (Ridgway); filaments glabrous; capsules about 4 mm wide and 3 mm long, 2- or 3-seeded; surface of seed not reticulated in lines. The area where the plant grows is usually inundated each year for weeks at a time. It is associated with Carya laciniosa, Liquidambar, and Quercus prinus.
