--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>small to moderate-sized, slender and soft, lax, moderately weak to moderately stiff-stemmed; green, pale yellowish green, yellowish brown, grayish brown or reddish brown; capitulum typically compact and twisted in the middle like a ball of yarn, spreading branches curved giving a pinwheel appearance. <b>Stems</b> pale green to pale brown, rarely with pinkish red patches, superficial cortex of undifferentiated to slightly differentiated cells. <b>Stem</b> leaves triangular-lingulate to lingulate, 0.7–1.3 mm, appressed to stem, apex obtuse to broadly obtuse and erose to somewhat lacerate, hyaline cells efibrillose and nonseptate. <b>Branches</b> curved, unranked to less commonly (in wet-grown forms) 5-ranked, leaves not much elongate at distal end. <b>Branch</b> fascicles with 2(–3) spreading and 2 pendent branches. <b>Branch</b> stems green but sometimes reddish at proximal end, with cortex enlarged with conspicuous retort cells. <b>Branch</b> leaves ovate-lanceolate to broadly ovate-lanceolate, 1.5–2.5 mm, strongly undulate and moderately recurved when dry, straight; margin entire; greater than hyaline cells on convex surface with 1–2 pores per cell at cell apex, on concave surface with round wall thinnings in the cell ends and angles; chlorophyllous cells triangular in transverse section and typically just slightly exposed on the concave surface. <b>Sexual</b> condition dioicous. <b>Spores</b> 23–25 µm; moderately to coarsely papillose on both surfaces; proximal laesura approximately 0.5 spore radius.</span><!--

|discussion=<p>Of species in sect. Cuspidata with range and ecology similar to that of <i>Sphagnum flexuosum</i>, <i>S. angustifolium</i> and <i>S. recurvum</i> have rounded stem leaves. In <i>S. angustifolium</i> the stem leaves are more triangular and rarely erose while the branch leaves are narrower and more strongly 5-ranked. <i>Sphagnum recurvum</i> also has narrower and more 5-ranked branch leaves than does <i>S. flexuosum</i>, as well as a much more strongly differentiated stem cortex. In <i>S. flexuosum</i> the branch leaves are only slightly recurved whereas in <i>S. recurvum</i> they are sharply recurved.</p>
