--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>without deciduous distal leaves. <b>Leaf</b> apex acute; costa subpercurrent; sheath clear or yellowish; limb green, pellucid; limb-sheath transition abrupt, not sharply angled; limb margins strongly dentate in distal half, with fewer and smaller teeth below, and a few small sharp teeth at limb-sheath transition; limb lamina cells (5–)7–16(–21) × (6–)7–12(–14) µm, with low rounded or flattened mamillae on the adaxial surface, abaxial surface smooth; abaxial surfaces of sheath lamina cells smooth or with 1–6 papillae over lumen; cells at leaf insertion not fragile and hyaline; abaxial surface of limb costa smooth (rarely papillose near leaf apex), adaxial cells with rounded or somewhat flattened mamillae. <b>Sexual</b> condition monoicous; perichaetial leaves narrower than vegetative leaves. <b>Calyptra</b> with a median longitudinal split, sometimes persistent on the neck of the capsule or seta. <b>Capsule</b> plicate or puckered when dry; exothecial cells with non-sinuose walls; stomata on urn; endostome cilia with numerous spine-like or branched-stellate appendiculations on the interior surfaces.</span><!--
