|discussion=<p><i>Carex lasiocarpa</i> is a dominant of boreal wetlands, often forming huge stands. Large stands of the species are quite striking at a distance because of their pale straw color derived from the dried and faded, curly, filiform leaf apices of the vegetative shoots. Sometimes extensive stands occur without fertile culms.</p><!--
--><p>The reported hybrids between <i>Carex lasiocarpa</i> and <i>C. stricta</i> require confirmation (J. Cayouette and P. M. Catling 1992).</p><!--
--><p>North American plants have, on average, slightly smaller perigynia and shorter beak teeth than European and Asian plants and have been distinguished as <i></i></i>subsp.<i><i> americana</i> (Fernald) Hultén.</p>
