Sparsely vegetated wet interdunal flats, where plants can be quite abundant, but are so small as to be virtually impossible to see unless specifically sought.
Although this tiny plant is considered to be the most widespread species of Utricularia in the world, in the United States it was thought to be restricted to the Coastal Plain from Massachusetts to Texas until it was discovered around the head of Lake Michigan in the 1980’s.The first Michigan collection was made by K. Klick in an interdunal flat at Warren Dunes State Park, Berrien Co., in 1987 (2766, MICH); M. R. Penskar collected it in similar habitats in Muskegon and Allegan Cos. in 1992 (MICH).
In Michigan colonies seem mostly produce only cleistogamous flowers, making them even harder to locate.
