--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>in thin, loose mats, light green to yellowish. <b>Stems</b> 2.5 cm, 1–3 mm wide, complanate-foliate. <b>Leaves</b> squarrose, not upturned-homomallous, distant, ovate- or oblong-lanceolate, asymmetric, cultriform, often strongly undulate, 0.3–1.8 × 0.2–0.6 mm; margins plane or narrowly recurved basally, serrulate to entire proximally, serrate to serrulate distally; apex acute to acuminate; costa double, strong; alar cells undifferentiated or quadrate to rectangular, 1–3 along margins; medial laminal cells 48–100 × 4–7 µm; distal cells sometimes prorulose at distal ends on abaxial surface. <b>Specialized</b> asexual reproduction often present as propagula clustered in leaf axils at or near stem apices, 0.1–0.5 mm, yellowish green, twisted-vermiform, with 1–5 acute, erect teeth at apex. <b>Sexual</b> condition autoicous. <b>Sporophytes</b> unknown.</span><!--

|discussion=<p><i>Pseudotaxiphyllum distichaceum</i> is easily confused with <i>P. elegans</i>, especially when propagula are absent. The asymmetric, often cultriform leaves of <i>P. distichaceum</i> will distinguish it from <i>P. elegans</i>, which has symmetric leaves that are never cultriform. When propagula are present, their location on the stems, as well as their morphology, are distinctly different in the two species. <i>Pseudotaxiphyllum distichaceum</i> has propagula that are elongate, twisted-vermiform with 1–5 acute teeth at the apices, and occur in the leaf axils at or near the stem apices, while <i>P. elegans</i> has propagula in the leaf axils always below the stem apices, and they resemble the parent plant, being much smaller, possessing small leaflike structures along their stems.</p>
