|discussion=<p>Previously, we (A. F. Cholewa and D. M. Henderson 1984) misidentified the octoploid northern Utah populations of <i>Sisyrinchium demissum</i> as <i>S. radicatum</i>. New data indicate that these northern Utah populations rightly belong here as a polyploid race of <i>S. demissum</i>. Also see discussion under 18. <i>S. radicatum</i>.</p>
