|discussion=<p>A. Cronquist (1980) and others have alluded to intermediates between <i>Heliopsis gracilis</i> and <i>H. helianthoides </i>var.<i> scabra</i> in Louisiana; I have seen none. <i>Heliopsis gracilis</i> is distinguishable from <i></i>var.<i> scabra</i> by the abaxially and adaxially glabrous or nearly glabrous leaf blades, smaller plant size, single or relatively few heads, and long-creeping, narrow rhizomes. Presence of <i>H. gracilis</i> in southeast Texas (D. S. Correll and M. C. Johnston 1970) has not been confirmed.</p><!--
--><p>I am uncertain whether the type of <i>Heliopsis</i> laevis <i></i>var.<i> minor</i>, collected from near New Orleans, is referable to <i>H. gracilis</i>, as A. Cronquist (1980) thought, or to <i>H. helianthoides </i>var.<i> scabra</i>, where it was placed by T. R. Fisher (1957) and others. If the latter, then <i></i>var.<i> minor</i> has priority over <i></i>var.<i> scabra</i>.</p>
