|discussion=<p>Outside of Europe most <i>Zannichellia</i> are considered to be <i>Z. palustris</i> (W. Van Vierssen 1982). In Europe three species have been recognized based on stamen length, fruit length, podogyne length, and the rostrum to fruit length ratio. For <i>Z. palustris</i> in Europe the mean rostrum length is 0.78 ± 0.20deletion} mm, the mean podogyne length is 0.4 ± 0.19 mm, and the rostrum to fruit ratio is less than 0.5 (W. Van Wierssen Vierssen 1982). North American <i>Zannichellia</i> does not match any of these figures exactly. In North America <i>Zannichellia</i> has been considered historically to comprise only one species, which has been called <i>Z. palustris</i>. Until further research determines the range of <i>Zannichellia</i> and species delimitations, we areI am continuing to consider all North American material to be monospecific and am are applying the name <i>Z. palustris</i> to our that material.</p>
