|discussion=<p>Indication of this species in Newfoundland (H. J. Scoggan 1978–1979) probably refers to <i>Lemna turionifera</i>.</p><!--
--><p>A specimen in the Gray Herbarium from St. Pierre and Miquelon may represent <i>Lemna minor</i> or <i>L. turionifera</i>; its determination is questionable.</p>
