|discussion=<p>I have not seen specimens from Washington and Wyoming; <i>Adonis aestivalis</i> is documented from Idaho immediately across the border from those states.</p><!--
--><p>Except for details of the achenes and the subtle differences in orientation of sepals and petals, <i>Adonis aestivalis</i> is much like <i>A. annua</i>. <i>Adonis aestivalis</i> has been divided into three variable subspecies, although only two [<i>Adonis aestivalis</i> subsp. aestivalis and <i></i>subsp.<i> parviflora</i> (de Candolle) N. Busch] seem to be well delimited morphologically and geographically in Eurasia (C. C. Heyn and B. Pazy 1989). North American material is not readily assigned to either subspecies.</p><!--
--><p>Petal color has been variously reported; in the flora only orange with a dark basal blotch is confirmed.</p>
