|discussion=<p><i>Hypericum microsepalum</i> is related to <i>H. cistifolium</i>, not to the other four-petaled species attributed to Ascyrum, and can be distinguished from it by the bushier habit and smaller leaves and by the usually four-merous flowers with larger petals.</p><!--
--><p><i>Hypericum</i> isophyllum Steudel is an illegitimate name for <i>H. microsepalum</i>.</p>
