|discussion=<p><i>Carex incurviformis</i> is an alpine member of the <i>C. maritima</i> complex, and seems clearly (though subtly) distinct from the widespread and variable <i>C. maritima</i>, which in North America is a lowland and mostly coastal species. It is tentatively accorded species rank pending a comprehensive, worldwide revision of the complex even though, in other regions, apparently typical <i>C. maritima</i> does occur in alpine settings.</p><!--
--><p>Plants of California especially and, to a lesser extent, the southern Rockies have broader, blunter scales with slighty wider hyaline margins than plants of the northern Rockies. California plants were described as <i>Carex</i> danaensis Stacey. As more collections accumulated, F. J. Hermann (1955) noted that the distinctions between C. danaensis and <i>C. incurviformis</i> were slight. He recognized C. danaensis only as a variety of <i>C. incurviformis</i> and expanded its range to include Colorado. With even more material the distinctions appear to be no more than a regional trend and are not given formal recognition.</p>
