|discussion=<p>Varieties 3 (3 in the flora).</p><!--
--><p><i>Carex scopulorum</i> is the common species of sect. Phacocystis in subalpine, seasonally wet meadows in the western mountains. It is replaced on the western slope of the Cascade range by <i>C. spectabilis</i>, a member of sect. Scitae. Where sympatric with <i>C. aquatilis</i>, <i>C. scopulorum</i> occurs in drier portions of the habitat.</p><!--
--><p><i>Carex scopulorum</i> is frequently confused with members of sect. Racemosae because of the similarity in habitat, size, inflorescence dimensions, and perigynium shape; it is distinguished by the two stigmas and flattened achenes. <i>Carex scopulorum</i> is probably most closely related to <i>C. bigelowii</i>, based on the similarity in vegetative morphology, hypostomic leaves, perigynia characteristics (absence of veins), and chromosome numbers.</p>
