|discussion=<p><i>Sciuro-hypnum uncinifolium</i> has long been considered a Japanese endemic, but recently it was found in Russia in Kamchatka and in the Kuril Islands (I. V. Czernjadieva and M. S. Ignatov 2006; V. Y. Cherdantseva et al. 2006) and also in islands near Alaska and in the Alaskan peninsula (M. S. Ignatov 2007), so it is to be expected in the Aleutian Islands. <i>Sciuro-hypnum uncinifolium</i> is easily recognized by its narrow shoots, appressed leaf bases, and leaves rigidly reflexed, with squarrose to falcate-secund acumina. This species combines the characters of <i>S. reflexum</i> (leaf shape and reflexed acumen) and <i>S. populeum</i> (opaque cells across the leaf base). From molecular phylogenetic analyses by Ignatov and I. A. Milyutina (2007b), it is more closely related to the latter species. Despite its autoicous condition, sporophytes are rare in this species.</p>
