|discussion=<p><i>Taxiphyllum alternans</i> is rare in North America. The species is recognized by leaves that are distant, ovate to broadly ovate-lanceolate with acuminate to filiform-acuminate, frequently twisted apices, plane margins, and 2–5 quadrate to short-rectangular cells in marginal rows. The species occurs in a few localities in the southeastern United States with disjunct occurrences in Maryland (Charles and Montgomery counties). This species has sometimes been confused with <i>Plagiothecium cavifolium</i> (Bridel) Z. Iwatsuki, but all <i>Taxiphyllum</i> species differ from <i>Plagiothecium</i> microscopically by their nondecurrent leaves and the presence of foliose pseudoparaphyllia.</p>
