--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>to 10 × 3 mm. <b>Stem</b> unbranched and branched; axillary hyaline nodules absent; central strand present or absent. <b>Leaves</b> as many as 20 pairs, elliptic to broadly lanceolate to oblong-lingulate, acute, short-acuminate to obtuse-apiculate, to 2 × 0.5 mm; dorsal lamina narrowed proximally, ending before insertion to ± decurrent; vaginant laminae 2/3–3/4 leaf length, equal; margin ± entire but usually serrulate distally, limbate on all laminae, limbidium usually ending a few cells before apex, frequently edged by 1–2 rows of quadrate to oblong chlorophyllose cells in proximal parts of vaginant laminae, limbidial cells 1–2-stratose; costa percurrent to ending 2–5 cells before leaf, infrequently short-excurrent, bryoides-type; laminal cells 1-stratose, smooth, strongly bulging, densely chlorophyllose, ± obscure, firm-walled, irregularly quadrate to hexagonal, usually arranged in discernable rows in distal part of leaf, 6–10 µm, twice as deep as wide. <b>Sexual</b> condition gonioautoicous and rhizautoicous. <b>Sporophytes</b> 1–2 per perichaetium. <b>Seta</b> to 9 mm. <b>Capsule</b> theca exserted, inclined, bilaterally symmetric to erect, radially symmetric, to 1 mm; peristome bryoides-type; operculum 0.5 mm. <b>Calyptra</b> cucullate, smooth, 0.8 mm. <b>Spores</b> 10–16 µm.</span><!--

|discussion=<p>Three species belong to the <i>Fissidens crispus</i> complex; <i>F. crispus</i>, <i>F. minutulus</i>, and <i>F. sublimbatus</i>. A well-developed limbidium and small (6–10 µm), bulging, obscure laminal cells that in transverse section are twice as deep as wide characterize all three.</p><!--
--><p><i>Fissidens crispus</i>, better known in western North America as F. limbatus, is highly variable and widespread, ranging widely in tropical America, where it also attains its greatest variability. It is best distinguished by laminal cells that are usually arranged in discernable rows in the distal parts of leaves. The dorsal lamina is quite variable, ending above the insertion to long-decurrent as in some tropical expressions. Leaves, when dry, are usually crispate. The limbidium is found on all or most leaves and usually extends to or ends just before the apex.</p>
