|discussion=<p><i>Barbula amplexifolia</i> belongs in sect. Convolutae by the convolute-sheathing perichaetial leaves, lack of hydroid cells in costa, and occasional prorulae on abaxial surface of costa. It is distinguished from <i>B. convoluta</i> most immediately by the stiff and sharply pointed leaves with a smooth, short mucro. On further study, the distinctions between B. coreensis (Cardot) K. Saito and this species made by M. S. Ignatov and R. H. Zander (1993) do not hold; e.g., the type of B. haringae has short, 65–75 µm, propagula and rough costal abaxial surface; a specimen from the Northwest Territories (Steere 76-605, NY) has rough costae and propagula variably 90–150 µm; the type of <i>B. amplexifolia</i> has a smooth costa and intermediate-sized propagula, ca. 90 µm. <i>Barbula convoluta </i>var.<i> eustegia</i> (as in the type of B. whitehouseae) may have a similarly stout costa, but the percurrent costa is apiculate only by a single, usually papillose cell and has narrower, nonsheathing leaves.</p>
