Water milfoils are submerged aquatic plants. All but one of Michigan's seven species are characterized by very dissected leaves that have the appearance of 2 sided combs.

Water milfoils are unrelated freshwater aquatic perennials of the genus Myriophyllum, sometimes grown in aquariums and ponds; Eurasian water milfoil is a pest species in some U.S. inland waters.
