--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>pale yellow-brown, grey-green, to dark brown. <b>Stems</b> green to brownish; superficial cortex of 1 and often irregularly 2 layers of inflated, thin-walled cells. <b>Stem</b> leaves triangular-lingulate to lingulate; 0.7–0.8 mm; apex rounded and often erose, hyaline cells nonseptate or sometimes 1-septate, numerous small round pores more than 2 µm along the commissures and scattered across the cell on the convex surface, on the concave surface fewer similar-sized pores along the commissures. <b>Branches</b> short and slightly curved Branch fascicles with 2 spreading and 2 pendent branches. <b>Branch</b> leaves ovate, 1.1–1.3 mm, distinctly curved to secund; hyaline cells covered with numerous (more than 30 per cell) tiny pores (ca. 1 µm) on convex surface along the commissures and across the cell surface, sometimes forming several linear rows of free pores, on concave surface with fewer pores round to oval and slightly larger (more than 2 µm) restricted to commissures. <b>Sexual</b> condition probably dioicous. <b>Capsule</b> not seen. <b>Spores</b> not seen.</span><!--

|discussion=<p>The ecology of <i>Sphagnum orientale</i> is poorly known, due in part to taxonomic confusion with <i>S. perfoliatum</i> and in part to its very northern distribution. Like other species of sect. Subsecunda, however, it is clearly minerotrophic, probably weakly so. Associated vascular plants include <i>Carex aquatilis</i> Wahlenberg, <i>C. bigelowii</i> Torrey, <i>C. fuliginosa</i> Schkuhr, <i>C. rotundata</i> Wahlenberg, <i>Eriophorum vaginatum</i> Linnaeus, <i>Vaccinium</i> oxycoccus Linnaeus, and <i>Betula glandulosa</i> Michaux. Associated bryophytes include <i>Sphagnum aongstroemii</i>, <i>S. fimbriatum </i>subsp.<i> concinnum</i>, <i>S. jensenii</i>, <i>S. obtusum</i>, <i>S. rubellum</i>, <i>S. talbotianum</i>, <i>S. squarrosum</i>, and <i>Cinclidium</i> subrotundatum. Sporophytes are rare. Similar species with which it overlaps in range are <i>S. subsecundum</i>, <i>S. perfoliatum</i> and <i>S. inexspectatum</i>. Field separation from <i>S. subsecundum</i> and <i>S. inexspectatum</i> is difficult but the tiny branch leaf pores will separate it microsopically. <i>Sphagnum perfoliatum</i> is much larger and indeed looks much like some forms of <i>S. lescurii</i> or S.auriculatum, even to having curved, horn-like branches. <i>Sphagnum perfoliatum</i> is also typically quite richly colored and glossy in appearance.</p>
