|discussion=<p><i>Sagittaria cuneata</i> is extremely variable. On emersed plants, the leaf petioles are often bent toward the ground. Submersed plants often grow from a basal rosette with a long flexuous petiole and a floating sagittate leave. Plants in deep rivers often develop broad, straplike phyllodia.</p>
