A native of Eurasia, widely distributed as a weed but not found in Michigan until 1920, when it was collected along a railroad near Ypsilanti, Washtenaw Co.; collected 1935–1937 in an alfalfa field and disturbed places in Kalamazoo Co.

Although, like our other species, this is a plant of dry disturbed ground, it has the aspect of many aquatics in its strong heterophylly, with dissected proximal leaves and entire distal leaves.
