--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>small to moderate-sized, soft and ± weak-stemmed; brownish green, yellow-green, yellowish to golden brown, capitulum typically flat and 5-radiate. <b>Stems</b> pale green to brown, branch bases sometimes reddish; superficial cortex of 2–3 layers of moderately thin-walled and differentiated cells. <b>Stem</b> leaves 0.8–1.1 mm, triangular-lingulate to lingulate, concave, spreading, apex broadly obtuse, hyaline cells fibrillose in apical region. <b>Branches</b> slender and tapering, often 5-ranked and decurved, leaves somewhat elongated at distal end. <b>Branch</b> fascicles with 2 spreading and mostly 1 pendent branch. <b>Branch</b> stem green, cortex enlarged with conspicuous retort cells. <b>Branch</b> leaves ovate-lanceolate, 1–1.7 mm, straight, slightly undulate and spreading; margin entire, hyaline cells on convex surface with 1–5 pores in cell ends and free near apex, on concave surface with round wall thinnings in cell ends and angles; chlorophyllous cells triangular in transverse section and well-enclosed on concave surface. <b>Sexual</b> condition dioicous. <b>Spores</b> 25–33 µm; smooth to finely papillose on both surfaces; proximal laesura approximately 0.5 spore radius.</span><!--

|discussion=<p>Unlike <i>Sphagnum angustifolium</i> and <i>S. annulatum</i>, <i>S. balticum</i> has stem leaves exerted at right angles to the stem. It also has fewer and weaker hanging branches than does <i>S. angustifolium</i>, which make the stem itself often visible and the stem leaves easier to see. <i>Sphagnum balticum</i> also lacks the paired pendent branch buds between the capitulum rays as seen in <i>S. angustifolium</i>.</p><!--
--><p>In <i>Sphagnum kenaiense</i> there are sometimes spreading stem leaves but this species has 2 hanging branches per fascicle.</p>
