Other info. - This aquatic species can be found scattered throughout much of Missouri but is apparently absent from the northwest quarter of the state. The plant is similar to another, A. subcordatum Raf., but the latter has petals which are equal to or shorter than the sepals and smaller fruits. A. subcordatum is more common in the state.
Plants of this genus are eaten by wildlife such as muskrats. The rhizomes are eaten as well as the leaves. Humans eat the roots as well.
