|discussion=<p>In <i>Climacium americanum</i>, the basal angles of leaves may abruptly extend beyond the leaf outline into an auricle, usually delineated from the distal leaf outline by a short undulation and a shoulder, in addition to being sharply rounded into the insertion area. The capsules of <i>C. americanum</i> are very much larger than those of <i>C. dendroides</i>.</p><!--
--><p><i>Climacium</i> kindbergii, treated here as a synonym of <i>C. americanum</i>, has been distinguished by a prostrate or decumbent, not dendroid-erect, habit. This habit is apparently a response to inundation although there is molecular evidence that C. kindbergii is reproductively isolated from <i>C. americanum</i> (A. J. Shaw et al. 1987b, 1994, 2012). Given that any isolation will encourage molecular differences, this is not conclusive of distinction at the species level.</p>
