|discussion=<p><i>Trichostomum portoricense</i> is a distinctive species with no immediate relatives in the genus. The deep, narrow groove down the adaxial surface of the leaf is reminiscent of that of species of <i>Barbula</i> or <i>Anoectangium</i>. The massive, caplike papillae are similar to those of <i>Tuerckheimia</i>, but the long-ligulate leaf shape of <i>T. portoricense</i> is diagnostic. The leaf lamina fragments easily in patches, and doubtless figures in asexual reproduction. The distribution was recently summarized by P. M. Eckel (2003).</p>
