|discussion=<p><i>Napaea dioica</i> is the only dioecious member of Malvoideae native in the Western Hemisphere. Reports of glade mallow in areas outside its natural range derive from confusion between it and <i>Sida hermaphrodita</i> (for example, Virginia; H. H. Iltis 1963) or from garden escapes (for example, Vermont; J. P. Brown 1941).</p><!--
--><p>The degree, distribution, and type of indument are variable. Forma stellata Fassett includes plants with mostly stellate hairs.</p><!--
--><p><i>Napaea dioica</i> is in the Center for Plant Conservation’s National Collection of Endangered Plants.</p>
