--><p><i>Claopodium</i> is a genus of small plants with creeping stems, short, papillose laminal cells, pellucid costa, and asymmetric brown capsules with a well-developed peristome. The leaves are broad at the base; the capsules have short necks, are constricted below the mouth when dry, and have bordered exostome teeth and nodose endostome cilia. The genus is somewhat heterogeneous, as <i>C. whippleanum</i> lacks hair-points and superficially is similar to <i>Leskea</i>. Recent phylogenetic work suggests that <i>Claopodium</i> is related to <i>Anomodon</i> (Anomodontaceae).</p>
