|discussion=<p>Barbula amplexifolia 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 B. convoluta 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 B. amplexifolia has a smooth costa and intermediate-sized propagula, ca. 90 µm. Barbula convoluta var. eustegia (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>
