|discussion=<p><i>Viola palustris</i> occurs in small colonies; individual plants are interconnected by stolons. When flowering, usually three or more leaves are present per caudex.</p><!--
--><p>M. Sorsa (1968) noted that in western North America <i>Viola palustris</i> specimens differ from European <i>V. palustris</i> plants and often show variation in character combinations. She stated (pers. comm.) that North American <i>V. palustris</i> is not a uniform entity.</p><!--
--><p>E. Hultén (1968) synonymized <i>Viola palustris</i> with <i>V. epipsila</i>, as did W. J. Cody (2000). G. W. Douglas et al. (1998–2002, vol. 5) recognized both species. We assume that <i>V. palustris</i> does not occur in Alaska; verification is needed. See additional discussion under 18a. <i>V. epipsila </i>var.<i> repens</i>.</p><!--
--><p>M. Sorsa (1968) indicated that <i>Viola palustris</i> var. brevipes has often been confused with <i>V. blanda</i> and that var. brevipes may have arisen from hybridization between a tetraploid and a diploid plant. Listed here in synonymy, var. brevipes may warrant recognition.</p><!--
--><p>Reports of <i>Viola palustris</i> from one location in Coconino County, Arizona, first collected in 1962, likely refer to <i>V. macloskeyi</i>.</p><!--
--><p><i>Viola palustris</i> hybridizes with <i>V. epipsila </i>var.<i> repens</i> (M. Sorsa 1968; T. Marcussen and T. Karlsson 2010).</p>
