|discussion=<p>There are very few recent North American collections of Althaea hirsuta. There is an old specimen of this plant from British Columbia dated 1924, but the species has not been collected in the province since then. Current molecular data suggest that it may belong within Malva.</p><!--
--><p>The name Althaea hispida Moench, which pertains here, is superfluous and illegitimate.</p>
