--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>robust and weak-stemmed; green, golden brown to dark brown; capitulum often flat-topped and with a visible terminal bud; flaccid and plumose in submerged forms to more compact in emergent or stranded forms. <b>Stems</b> green to brown; superficial cortex of 1–2 layers of moderately thick-walled and poorly differentiated cells. <b>Stem</b> leaves triangular, large, less than 1.7 mm, mostly appressed to stem, apex weakly apiculate to narrowly obtuse; hyaline cells efibrillose and seldom to often septate at base and sides. <b>Branches</b> unranked, long and tapering, leaves greatly elongate at distal end. <b>Branch</b> fascicles with 2 spreading and 2 pendent branches. <b>Branch</b> stem green, cortex enlarged with conspicuous retort cells. <b>Branch</b> leaves ovate-lanceolate to lanceolate in aquatic forms, ovate to ovate-lanceolate in emergent forms, greater than 2.5 mm, often falcate-secund, especially in submerged forms, weakly undulate and recurved when dry; margin entire, hyaline cells on convex surface with 0–1 pores per cell, concave surface with round wall thinnings in the cell apices and angles; chlorophyllous cells narrowly triangular in transverse section and well-enclosed on the concave surface. <b>Sexual</b> condition dioicous. <b>Sporophytes</b> not seen.</span><!--

|discussion=<p>Sporophytes of <i>Sphagnum atlanticum</i> are rare. The other large North American Atlantic coastal plain species of sect. Cuspidata, <i>S. torreyanum</i>, is typically more yellow, has a more rounded capitulum, and has straight rather than subsecund branch leaves.</p>
