|discussion=<p><i>Carex subspathacea</i> is evidently, with <i>C. rufina</i>, the smallest species of sect. Phacocystis. Larger plants with one to two staminate spikes and some bisexual spikes frequently occur in Ungava Bay, Hudson Bay, Northwest Territories, and Alaska, but their perigynium and achene characteristics are typical of <i>C. subspathacea</i>.</p><!--
--><p>The following hybrids have been examined and are recognized: <i>Carex</i> ×flavicans F. Nylander (= <i>C. subspathacea</i> × <i>C. aquatilis</i>), C. ×arctophila F. Nylander (= <i>C. subspathacea</i> × <i>C. bigelowii</i>), C. ×subreducta E. Lepage, (= <i>C. subspathacea</i> × <i>C. bigelowii</i>), C. ×reducta S. Drejer (= <i>C. subspathacea</i> × <i>C. nigra</i>), C. ×dumanii E. Lepage (= <i>C. subspathacea</i> × <i>C. paleacea</i>), C. ×kenaica E. Lepage (= <i>C. subspathacea</i> × <i>C. ramenskii</i>), C. ×soerensenii E. Lepage (= <i>C. subspathacea</i> × <i>C. rariflora</i>), C. ×gauthieri E.
