|discussion=<p>Of conservation concern.</p><!--
--><p><i>Clematis coactilis</i> is known only from western Virginia. C. S. Keener (1967, 1975) suggested that this species may be a stabilized derivative of past hybridization between <i>C. albicoma</i> and <i>C. ochroleuca</i>.</p><!--
--><p>In fruit, <i>Clematis coactilis</i> is distinguishable from <i>C. ochroleuca</i> by its combination of spreading to reflexed hairs on the achene rims and whitish to pale yellow (rarely tawny) hairs on the beaks, contrasting with the strongly ascending hairs on the achene rims and tawny (rarely yellowish white) hairs on the beaks of <i>C. ochroleuca</i>. This species and <i>C. ochroleuca</i> lack stomates on the adaxial surface of the leaves, whereas the closely related species <i>C. albicoma</i>, <i>C. fremontii</i>, and <i>C. viticaulis</i> have stomates on both leaf surfaces (C. S. Keener 1967).</p>
