|discussion=<p><i>Ruppia</i> spiralis Linnaeus has occasionally been used for this taxon in North America. Linnaeus, however, had never published that name (J. T. A. Verhoeven 1979). <i>Ruppia cirrhosa</i> is, indeed, the correct name for the taxon (J. C. Gamerro 1968).</p><!--
--><p>An implication that the North American material with long, spiraling peduncles is different from the European material of <i>Ruppia cirrhosa</i> stems from the statement that <i>R. occidentalis</i> occurs in inland lakes (J. T. A. Verhoeven 1979). No differences between European <i>R. cirrhosa</i> and the North American material are listed, however. In fact, a comparison of the Verhoeven's descriptive discussions for of <i>R. cirrhosa</i> (Verhoeven 1979) with the North American material shows that the two are the same. The genus should be studied on a worldwide basis. Until further studies indicate otherwise, I am considering North American and European material to be conspecific.</p>
