--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>moderately robust and lax; terminal bud somewhat enlarged; yellow-green to light brownish green. <b>Stems</b> yellow-green; superficial cortex of 1–2 layers of moderately enlarged cells. <b>Stem</b> leaves broadly oblong-triangular, 1.2–1.5 mm; mostly appressed to stem; apex obtuse; hyaline cells narrow, usually nonseptate, efibrillose and aporose on convex surface near apex, on concave surface usually efibrillose with irregular pores along commissures in distal portion of leaf. <b>Branches</b> with loosely imbricate leaves; often 5-ranked; leaves little to somewhat elongated at distal end. <b>Branch</b> fascicles with 2 spreading and 2–3 pendent branches. <b>Branch</b> stems green, with cortical cells in 1 layer with conspicuous necks. <b>Branch</b> leaves ovate, ovate-lanceolate to lanceolate; 2–3.5 mm; flat and undulate at margins and recurved at apex when dry; straight; margins entire; hyaline cells on concave surface with very numerous, small ringed or unringed pores along the commissures, 5–12 in distal portion of leaf and 20–27 in proximal portion, convex surface with 5–15 pores per cell in distal portion of leaf and 14–21 in proximal portion, pores usually without a ring; chlorophyllous cells triangular to trapezoidal in transverse section and exposed slightly on concave surface. <b>Sexual</b> condition dioicous. <b>Spores</b> ca. 30 µm; very slightly roughened.</span><!--

|discussion=<p>Sporophytes of <i>Sphagnum mendocinum</i> are uncommon. Although the unique branch leaf porosity makes it unmistakable microscopically, it may be confused with other species in the field. It is unusual ecologically in that it seems to overlap both the carpet- and lawn-forming habits—in other words it seems intermediate between <i>S. recurvum</i> and <i>S. cuspidatum</i>, in the broad sense. Among the species that it overlaps floristically, it is more robust and darker colored than <i>S. pacificum</i>. The latter also has an apiculate stem leaf compared to the more or less obtuse stem leaves of <i>S. mendocinum</i>. The more wet-growing <i>S. majus</i> <i></i></i>var.<i><i> majus</i> and <i>S. majus</i> var. norvegicum, with which it slightly overlaps in habitat, have branch leaves that are strongly elongated at the distal branch ends whereas those of <i>S. mendocinum</i> are not. See also discussion under 40. <i>S. obtusum</i>. Sexual condition and spore characters are taken from from H. A. Crum (1984).</p>
