|discussion=<p><i>Carex scirpoidea </i>subsp.<i> scirpoidea</i> is the widest ranging of the subspecies and includes taxa formerly recognized by other caricologists. G. Kükenthal (1909) recognized <i>C. scirpoidea</i> var. europaea from a single locality in Norway. These plants are short in stature, like plants of <i>C. scirpoidea </i>subsp.<i> scirpoidea</i> from alpine habitats, and values for most morphologic characters fall within the normal range for <i></i>subsp.<i> scirpoidea</i>. Another taxon, C. scirpiformis, was recognized by K. K. Mackenzie (1908) and treated at the varietal rank by H. O’Neill and M. Duman (1941) based on wide, hyaline pistillate scale margins and light-colored pubescence. Width of the hyaline portion of the scale margins and the color of pubescence are extremely variable characters in the group. F. J. Hermann (1957) recognized C. athabascensis as a separate species based on the overall robust habit and small, ovoid achenes. Achenes from the type specimens fall at the wide end of the range of variation of achene width in <i>C. scirpoidea</i>.</p><!--
--><p><i>Carex scirpoidea </i>subsp.<i> scirpoidea</i> is recognized by the lack of persistent leaf bases on the flowering shoots, ovate perigynia that are tightly enveloped by the perigynia on all sides, and leaves widely V-shaped in transverse section.</p>
