|discussion=<p><i>Fontinalis sphagnifolia</i> has two different leaf forms. Leaves formed after a prolonged dry period (vernalis expression) or in sluggish water are medium-sized, loosely flaccid, ovate-lanceolate, plane to weakly concave, and have plane or erect to incurved apical margins. Leaves formed late in the aquatic period (aestivalis expression) or in faster moving streams are smaller, stiff, linear-lanceolate, strongly concave, and have consistently erect to incurved apical margins. Many specimens have a combination of vernalis expression and aestivalis expression leaves. The leaves in the lescurii expression are small and linear-lanceolate but flaccid, and have a mixture of plane and erect apical margins. When well developed, the vernalis expression of <i>F. sphagnifolia</i> has stem leaf apices with quadrate to short-rhomboidal laminal cells, erroneously considered an important feature of the species. <i>F. dalecarlica</i> differs in having ovate-lanceolate to lanceolate leaves with plane to erect apical leaf margins. Large expressions of <i>F. sullivantii</i> can be similar in size and aspect to the lescurii expression of <i>F. sphagnifolia</i>, but that species has consistently plane apical leaf margins.</p>
