|discussion=<p><i>Eleocharis aestuum</i> is very similar to <i>E. diandra</i> and <i>E. ovata</i>; <i>E. diandra</i> differs from <i>E. aestuum</i> in its lower tubercles, brown floral scales, and absence of perianth bristles; <i>E. ovata</i> differs as given in the key to species. D. M. Hines (1975) described <i>E. aestuum</i> using the epithet “palidostachys” [ined.]. Specimens from shores of the Lake-of-the-Woods in Minnesota, and a reservoir and farm in Hardin and Fayette counties, Tennessee, may be referable to <i>E. aestuum</i>. The only recent records of <i>E. aestuum</i> are from the Androscoggin and Kennebec rivers in Maine and the Hudson River in New York (A. Haines 2001).</p>
