Three populations of Leersia lenticularis Michx. were located in western Ohio in 1991. All sites are within the floodplain of the St. Marys River, a tributary of the Maumee River and the Lake Erie basin. These stations are the first known for this species from the Great Lakes drainage. The Maumee Terrace, formed by overflow waters from prehistoric Lake Maumee, is a possible avenue of plant migration from the Mississippian drainage Wabash River into Lake Erie tributaries.
