--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>moderate-sized to fairly robust; strong-stemmed and generally compact, capitulum usually not much enlarged; greenish brown to deep golden brown; forming compact carpets in floating mats and depressions as well as dense stands on hummock sides and low hummocks. <b>Stems</b> brown, superficial cortical layer with spiral reinforcing fibrils visible; usually 1–2 pores per cell, comb-fibrils lacking on interior wall. <b>Stem</b> leaves to 1.3 × 0.7 mm; rarely hemiisophyllous; hyaline cells non-ornamented, mostly septate. <b>Branches</b> generally short and blunt, leaves spreading. <b>Branch</b> fascicles with 2 spreading and 2–3 pendent branches. <b>Branch</b> stems with hyaline cells non-ornamented, no or weak funnel-like projections on the interior end walls, mostly with 1 pore per cell on superficial cell wall. <b>Branch</b> leaves broadly ovate, 1.7 × 1 mm; hyaline cells on convex surface with round to elliptic pores along the commissures, hyaline cell walls covered with papillae where overlying chlorophyllous cells; chlorophyllous cells trapezoidal to truncate-elliptic in transverse section, equally exposed on both surfaces or less exposed on convex surface, end walls thickened. <b>Sexual</b> condition dioicous. <b>Capsule</b> with numerous pseudostomata. <b>Spores</b> 26–36 µm; more roughly papillose on distal surface than proximal surface, distinct raised, bifurcated-Y mark sculpture on distal surface; proximal laesura 0.5 spore radius or more.</span><!--

|discussion=<p><i>Sphagnum papillosum</i> is often easily field-identifiable by its rich golden brown to dark brown color and short, blunt branches. Nearly all specimens have the papillae on the branch leaf chorophyll cells but a few smooth forms have been found. Such forms will have stem leaves with divided hyaline cells whereas in the confusable species <i>S. palustre</i> and <i>S. centrale</i> such cells are rare or absent.</p>
