|discussion=<p>Although <i>Eleocharis ovata</i> has often been confused with <i>E. obtusa</i>, B. M. H. Larson and P. M. Catling (1996) showed that these species may be distinguished by non-overlapping widths of the tubercles, at least in Canada. The records of <i>E. ovata</i> in New Brunswick, Newfoundland, Nova Scotia, and Prince Edward Island are based on B. M. H. Larson and P. M. Catling (1996) and the records in Illinois, Indiana, Missouri, Montana, New Jersey, Oregon, and Washington are based on D. M. Hines (1975). <i>Eleocharis ovata</i> probably also occurs in Manitoba and Saskatchewan.</p>
