A native of the southeastern states, from Texas to Florida northward, this species has become established as far north as New England and southern Michigan, perhaps escaped from cultivation; it is a popular aquarium plant. It was first collected in 1935 in Kalamazoo Co.
This is our only aquatic vascular plant with opposite (rarely whorled) much-dissected leaves on distinct petioles (5–15 mm long on well-developed leaves). The palmate pattern of dissection results in a characteristic fan-shaped leaf.
