|discussion=<p><i>Carex laeviculmis</i> is divergent from the rest of the members of <i>Carex </i>sect.<i> Deweyanae</i> and may not belong to this section. Compared to the other taxa in the section, <i>C. laeviculmis</i> has shorter, more spreading perigynia, with lower length to width ratios and shorter beaks. In this flora, placement of <i>C. laeviculmis</i> in <i>Carex </i>sect.<i> Deweyanae</i> follows the recommendation of A. A. Reznicek and P. W. Ball (1980), although K. K. Mackenzie’s (1931–1935, parts 2–3, pp. 99–114) placement of this species in <i>Carex </i>sect.<i> Stellulatae</i> may be correct.</p><!--
