|discussion=<p>Napaea dioica 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 Sida hermaphrodita (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>Napaea dioica is in the Center for Plant Conservation’s National Collection of Endangered Plants.</p>
