|discussion=<p>Variable features in <i>Amblystegium serpens</i> include the serration of the leaf margin, which ranges from entire to serrulate or even serrate; length of the costa, from very short (less than 1/5 of leaf length) to subpercurrent; the subquadrate to transversely elongate alar cells; and leaf stance, which ranges from erect to spreading. These last two characters have sometimes been used to recognize a separate taxon, var. juratzkanum. However, the continuous range of variation of these characters precludes any infraspecific division within <i>A. serpens</i>, which is a fairly well-circumscribed species with comparatively low levels of plasticity with regard to species of <i>Hygroamblystegium</i>.</p>
