--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>robust and weak-stemmed; yellow to light brown; capitulum flat-topped and with ± conspicuous terminal bud. <b>Stems</b> light green; superficial cortex of 1–2 layers of moderately differentiated thin-walled cells. <b>Stem</b> leaves equilateral triangular, 0.8–1.1 mm; often spreading; apex more or less obtuse; leaves often spreading; hyaline cells usually septate and often fibrillose in proximal half of leaf. <b>Branches</b> unranked, ± straight, leaves moderately elongated at distal end. <b>Branch</b> fascicles with 2 spreading and 1–2 pendent branches. <b>Branch</b> stems green, with cortex enlarged with conspicuous retort cells. <b>Branch</b> leaves ovate-lanceolate, less than 2.2 mm, straight; undulate and sharply recurved when dry; margins entire; hyaline cells on convex surface with 0–1 apical pores and often with pseudopores, concave surface with to 12 round wall thinnings in cell angles and sometimes along commissures; chlorophyllous cells triangular in transverse section, just enclosed on the concave surface and broadly exposed on the convex surface. <b>Sexual</b> condition unknown. <b>Spores</b> not seen.</span><!--

|discussion=<p>Sporophytes of <i>Sphagnum mcqueenii</i> are unknown. <i>Sphagnum torreyanum</i> and <i>S. atlanticum</i> both have longer, narrower, and less sharply recurved branch leaves than does <i>S. mcqueenii</i>. Both <i>S. cuspidatum</i> and <i>S. viride</i> have acute stem leaves as compared to the obtuse stem leaves of this species. <i>Sphagnum pulchrum</i> has 5-ranked branch leaves and apiculate stem leaves, which contrast strongly with the unranked branch leaves and obtuse stem leaves of this species.</p>
