|discussion=<p><i>Carex laxiculmis </i>var.<i> copulata</i> has been treated as a variety of <i>C. digitalis</i> or <i>C. laxiculmis</i>, as a distinct species, and as a hybrid between <i>C. digitalis</i> and <i>C. laxiculmis</i>. Regular pairing during metaphase-I indicates that <i>C. laxiculmis </i>var.<i> copulata</i> is not a by-product of hybridization (R. F. C. Naczi 1999). In lateral spikes, a proximal sterile scale or scale subtending a staminate flower clearly places the affinity of this variety with <i>C. laxiculmis</i> rather than <i>C. digitalis</i> (C. T. Bryson 1980).</p>
