|discussion=<p><i>Orontium aquaticum</i> is probably the most distinctive species of Araceae growing in North America. It is the only species that does not have a spathe, and the characteristic blue-green velvety leaves are not easily confused with those of any other plants. The unique appearance of the leaf blade of <i>O. aquaticum</i> is partly because of the waxy epidermal layer, which readily sheds water. The leaves also have large intercellular air spaces that contribute to their buoyancy.</p><!--
--><p>Specimens of <i>Orontium aquaticum</i> supposedly collected in Iowa are almost certainly a labeling error. Populations occur primarily on the Atlantic and Gulf coastal plains and less frequently in the Appalachian region.</p><!--
--><p><i>Orontium aquaticum</i> and <i>Peltandra virginica</i> may have been used somewhat interchangeably by Native Americans and may be confused at times in the literature. Seeds of <i>O. aquaticum</i> were either dried or boiled repeatedly in water before being eaten by Native Americans; Swedish settlers also used the seeds in a similar manner (P. Kalm 1770–1771). Fresh seeds microwaved for 5 minutes in tap water have a "firm texture and pleasant, nutty flavor" and produce no irritation (L. H. Klotz 1992). <i>Orontium aquaticum</i> is sometimes grown for its attractive foliage and bright yellow spadices in aquatic gardens. It is available through catalog sources.</p>
