|discussion=<p><i>Salix pseudomyrsinites</i> occurs in Nunavut on Akimiski Island in James Bay.</p><!--
--><p><i>Salix pseudomyrsinites</i> and <i>S. myrtillifolia</i>, although sometimes treated as conspecific (R. D. Dorn 1975), deserve species rank. They differ in chromosome number and are distinct in habit, habitat, and general appearance, including glossiness of leaves, as well as a number of technical characteristics (L. A. Viereck and E. L. Little Jr. 1972; G. W. Argus 1973, 1997). There is no field evidence of hybridization, but some herbarium specimens appear to be intermediates, having the habit or habitat of one species and the leaf hairiness of the other.</p><!--
--><p><i>Salix myrtillifolia</i> is distinguished from <i>S. pseudomyrsinites</i> by having shrubs low, decumbent, 0.1–0.6 m, rarely to 1 m, of treed bogs and fens, juvenile and mature leaves typically glabrous, stipules usually rudimentary, 0.2–1.8(–5) mm, and styles often shorter, 0.3–0.7 mm; <i>S. pseudomyrsinites</i> has shrubs tall, erect, 1–7 m, of riparian habitats, juvenile leaves pubescent with hairs persisting on mature leaves, at least on adaxial midrib, stipules usually prominent and foliaceous, 0.6–8 mm, and styles often longer, 0.4–1.6 mm.</p><!--
--><p>The nomenclature of these species is confusing. When treating them as varieties E. Hultén (1968) used the name <i>Salix myrtillifolia</i> var. pseudomyrsinites and R. D. Dorn (1975) used the name <i>S. myrtillifolia</i> <i></i>var.<i> cordata</i>. At the species level, the name <i>S. novae-angliae</i> was used (L. A. Viereck and E. L. Little Jr. 1972; G. W. Argus 1973), but that name is illegitimate (Dorn) and is replaced by <i>S. pseudomyrsinites</i> (Argus 1997).</p><!--
--><p>Hybrids:</p><!--
--><p><i>Salix pseudomyrsinites</i> forms natural hybrids with <i>S. barrattiana</i>.</p><!--
--><p><i>Salix pseudomyrsinites</i> × <i>S. barrattiana</i> is a rare hybrid that combines the characters of the two parents.</p>
