|discussion=<p><i>Carex hystericina</i> is widespread and common, even weedy, in regions with calcareous substrates. It hybridizes uncommonly with <i>C. pseudocyperus</i> and more rarely with <i>C. comosa</i>, <i>C. schweinitzii</i>, <i>C. utriculata</i>, and <i>C. vesicaria</i>. Hybrids are sterile and intermediate in morphology. The species epithet is often, but not originally, spelled “hystricina.”</p>
