|discussion=<p><i>Carex pedunculata</i> is one of the early-flowering woodland sedges. Its achenes are subtended by elaiosomes, which facilitate dispersal by serving as attractants and food sources for ants (S. Handel 1976). This species has been characterized as a “fugitive species,” colonizing openings in woodlands, and decreasing in abundance as other woodland species begin to compete with it.</p><!--
--><p><i>Carex pedunculata</i> exhibits the classical eastern North Americaneastern Asian disjunct distribution pattern (P. W. Ball 1990). The Korean counterpart is known as var. erythrobasis (H. Léveillé & Vaniot) T. Koyama.</p>
