--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>moderate-sized and moderately weak-stemmed to moderately stiff; green, brownish green to brown; capitulum flat-topped and 5-radiate, terminal bud often visible. <b>Stems</b> pale green, rarely with red coloration, superficial cortex of 2 layers of moderately to well differentiated cells. <b>Stem</b> leaves triangular to lingulate-triangular, equal to or more than 0.8 mm, spreading to appressed; apex acute to apiculate, hyaline cells mostly efibrillose and nonseptate. <b>Branches</b> ± straight and somewhat tapered, usually 5-ranked, leaves not greatly elongated at branch distal end. <b>Branch</b> fascicles with 2 spreading and 2–3 pendent branches. <b>Branch</b> stems green and often reddish at proximal end, with cortex enlarged with conspicuous retort cells. <b>Branch</b> leaves narrowly ovate-lanceolate, greater than 1.2 mm, straight, slightly undulate and weakly recurved when dry, margins entire; hyaline cells on convex surface with 1 pore per cell in apical end, on concave surface with round wall thinnings in the cell ends and angles; chlorophyllous cells in transverse section triangular to ovate-triangular and well-enclosed on the concave surface. <b>Sexual</b> condition dioicous. <b>Spores</b> 24–33 µm; finely papillose on the superficial surface.</span><!--

|discussion=<p>Sporophytes are uncommon in <i>Sphagnum isoviitae</i>. See discussion under 26. <i>S. brevifolium</i> and 28. <i>S. fallax</i> for distinction from these similar species. <i>Sphagnum isoviitae</i> has no range overlap with <i>S. pacificum</i>, the other North American species of the <i>S. recurvum</i> complex with apiculate stem leaves; the sharply recurved branch leaves of the latter, however, would separate it easily in any case. Spore features are those given by Flatberg.</p>
