|discussion=<p>Although <i>Carex oklahomensis</i> resembles <i>C. stipata</i> in inflorescence and perigynium characteristics, <i>C. oklahomensis</i> is distinguished by its firm, obtuse-angled stems, bladeless basal sheaths, and tubular extension of the smooth sheath fronts.</p><!--
--><p>Northern and eastern records of <i>Carex oklahomensis</i> are mostly recent and the species may be increasing its range.</p>
