|discussion=<p><i>Plagiomnium carolinianum</i> and <i>P. undulatum</i>, an apparent introduction in British Columbia, are differentiated from other species of <i>Plagiomnium</i> by their long, usually oblong-lingulate or lingulate leaves, which are transversely undulate when moist, and the relatively small size of the laminal cells. <i>Plagiomnium undulatum</i>, to date known only from south-coastal British Columbia, is a much larger plant than <i>P. carolinianum</i> with longer leaves, and its erect stems often branch distally, forming irregular, palm treelike heads. While other species of <i>Plagiomnium</i> have straight capsules, the capsules of <i>P. carolinianum</i> are slightly curved when dry.</p>
