|discussion=<p><i>Sanionia uncinata</i> is the only North American species of the genus with a perfect peristome and usually curved and horizontal capsules. When the shoot is examined from the dorsal side, the leaves of normally developed shoots appear to be combed, with leaves pointing stiffly, obliquely forwards-outwards; weak plants growing in relatively dry situations on rocks or tree stems may have less distinctly combed leaves that are sometimes non-plicate or almost so. From all except <i>S. symmetrica</i>, <i>S. uncinata</i> is separated by the structure of the alar and supra-alar cells. <i>Sanionia uncinata</i> is usually somewhat smaller and more regularly pinnate than <i>S. orthothecioides</i>.</p><!--
--><p>The identity of <i>Hypnum</i> uncinatum var. plumulosum Bruch & Schimper [<i>Drepanocladus</i> uncinatus var. plumulosum (Bruch & Schimper) Warnstorf] is somewhat unclear because no type material seems to be extant; most of the North American material referred to this name belongs to typical <i>Sanionia uncinata</i>. Type material of <i>Hypnum</i> (Harpidium) moseri Kindberg (<i>Hypnum</i> uncinatum subsp. moseri) could not be found among material of Kindberg in Stockholm. However, since this taxon should differ from <i>S. uncinata</i> mainly in its non-plicate leaves, and non-plicate leaves occur in some expressions of the latter, it is unlikely to represent a separate taxon.</p>
