|discussion=<p>Intermediates between Nuphar microphylla and N. variegata, probably of hybrid origin, are treated as N. rubrodisca. A form with ten sepals (Nuphar microphyllum forma multisepalum Lakela) occurs in northeastern Minnesota. Recent observations of the Eurasian N. pumila (Timm) de Candolle by C. B. Hellquist in Siberia suggest that Beal's lumping of N microphylla under N. lutea subsp. pumila (Timm) E. O. Beal should be further studied.</p>
