--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>moderate-sized and lax to somewhat compact, ± stiff-stemmed; moderate-sized to large, forming lawns or low, loose hummocks; green, yellow-brown to golden brown and often tinged with brown to purplish brown; capitulum ± flat in lax open-grown forms to ± rounded and compact in open-grown forms. <b>Stems</b> brown, superficial cortical layer with spiral reinforcing fibrils clearly visible, usually 2 or more pores per cell, comb-fibrils visible on interior wall. <b>Stem</b> leaves to 1.3–1.9 × 0.6–1.2 mm; rarely hemiisophyllous; hyaline cells non-ornamented, nonseptate or sometimes septate. <b>Branches</b> ± tapering, leaves loosely imbricate to spreading and often squarrose in shade forms. <b>Branch</b> fascicles with 2 spreading and 2–3 pendent branches. <b>Branch</b> stems with cortical cell comb-lamellae weakly differentiated on interior wall, no or weak funnel-like projections on the interior end walls, pores in superficial wall mostly restricted to leaf attachments. <b>Branch</b> leaves ovate to ovate elliptical, 1.5–2 × 0.9–1.6 mm; hyaline cells on convex surface with elliptic to more often round pores along the commissures, comb-lamellae can be present, but often absent or restricted to leaf bases; chlorophyllous cells broadly triangular in transverse section and well-enclosed on the convex surface; end wall not thickened. <b>Sexual</b> condition dioicous. <b>Capsule</b> with scattered pseudostomata. <b>Spores</b> 27–31 µm; granulate on both surfaces; laesura on proximal surface less than 0.5 the spore radius.</span><!--

|discussion=<p><i>Sphagnum affine</i> may occur elsewhere but the taxonomy is unclear (K. I. Flatberg 1984). Although species of sect. <i>Sphagnum</i> are notoriously difficult to tell apart in the field, <i>S. affine</i> is typically smaller than <i>S. centrale</i>, <i>S. palustre</i>, and <i>S. papillosum</i>, the other brown species of this section with which it may occur. It is also much more likely to have somewhat squarrose branch leaves, especially in shade forms.</p>
