--><span class="statement" id="st-undefined" data-properties=""><b>Stem </b>leaves patent to erect-spreading, concave, lamina 1-stratose throughout; proximal leaves minute and bract-like, long-deltoid, subulate, 0.38–0.8 × 0.15–0.23 mm, entire proximally, minimally serrulate to entire distally; distal stem leaves with oblong-ovate base, apex subulate, 1.03–2.13 × 0.18–0.35 mm, entire proximally, infrequently serrulate distally; costa narrow, percurrent. <b>Perichaetial</b> leaves oblong-ovate, gradually narrowed to long-subulate, frequently crisped awn, 2.25–3.43 × 0.23–0.4 mm, margins entire proximally, irregularly serrate to serrulate distally in the subula; basal cells loosely rectangular; median cells irregular, subquadrate to short-rectangular to rhomboidal; distal cells in subula oblong to trapezoidal; costa percurrent, filling the tubulose subula; transverse section of costa at mid leaf with central guide cells forming a row across the width between a more restricted band of adaxial stereids and an extensive abaxial stereid band, accessory cells sandwiched in the center; innermost perichaetial leaves ovate, more or less sheathing base and acuminate tip, subpercurrent. <b>Specialized</b> asexual reproduction absent. <b>Sexual</b> condition autoicous, antheridia naked in persistent axillary leafy buds, one to several along the distal part of stem. <b>Seta</b> 0.25–0.53 mm. <b>Spores</b> 25–31.3 µm, densely and finely papillose, light orange-brown in mass.</span><!--

|discussion=<p>The chromosome number of <i>Pleuridium subulatum</i> is n = 13 (V. S. Bryan 1956; H. A. Crum and L. E. Anderson 1981; A. J. E. Smith and M. E. Newton 1968). It and <i>P. acuminatum</i> are morphologically similar. <i>Pleuridium subulatum</i> is distinguished by its autoicous sexual condition and 1-stratose lamina at leaf shoulder.</p>
