|discussion=<p><i>Carex planispicata</i> is frequent. Often, it grows with <i>C. abscondita</i>, <i>C. amphibola</i>, and <i>C. oligocarpa</i>. When <i>C. oligocarpa</i> and <i>C. planispicata</i> co-occur, <i>C. planispicata</i> usually grows lower on slopes than <i>C. oligocarpa</i>, though the two do occasionally grow intermingled.</p><!--
--><p>Until its description, <i>Carex planispicata</i> was long treated as <i>C. amphibola</i> or <i>C. amphibola</i> <i></i>var.<i> rigida</i> (R. F. C. Naczi 1999).</p>
