|discussion=<p>N. L. Gil-Ad (1997) presented evidence based on seed coat micromorphology that some plants known as <i>Viola palmata</i> are hybrids between plants with lobed and unlobed leaves and believed the type specimen to be hybrid in origin. He chose not to recognize the name <i>V. palmata</i>, choosing instead to recognize <i>V. triloba</i>. If the type specimen does represent a hybrid, Gil-Ad would be correct in recognizing <i>V. triloba</i>. Because the purity of the type specimen cannot be ascertained, we consider <i>V. palmata</i> the most appropriate name for this taxon. We acknowledge the presence of hybrids between lobed and unlobed plants; such hybrids obscure lines of demarcation. Some herbarium specimens may represent such hybrids; we feel most do not.</p><!--
--><p>L. E. McKinney (1992) described the nomenclatural history of <i>Viola palmata</i>. Homophylly versus heterophylly differentiates <i>V. palmata</i> from <i>V. subsinuata</i>, the homophyllous violet most often called <i>V. palmata</i>. We know that the taxon described by Linnaeus was heterophyllous, with some undivided leaf blades.</p><!--
