|discussion=<p><i>Primula borealis</i> varies in height, leaf morphology, and amount of farina, characters that are all influenced by ecology and phenology. Exposed dune populations are often composed of depauperate individuals; inland populations in protected or nutrient-rich sites can contain individuals over 10 cm in height with more flowers. Younger individuals are almost always farinose; farina sometimes disappears later in the growing season. The species characteristically shows a broad corolla and a full symmetrical umbel on a relatively short scape giving a top-heavy appearance at anthesis. Involucral bracts are saccate or gibbous, in comparison to the often sympatric species <i>P. anvilensis</i> and <i>P. nutans</i>, with plane and auriculate bracts, respectively. Inland populations previously identified as <i>P. borealis</i> should generally be placed under <i>P. mistassinica</i>, which can be distinguished by its more delicate appearance and usually efarinose vegetative parts. Plants from near Kotzebue, Alaska, called <i>P. mistassinica</i> by L. A. von Chamisso and D. F. L. von Schlectendahl (1826–1836) belong to <i>P. borealis</i>.</p><!--
--><p>In the Russian Far East and Japan, it is difficult to separate the North Pacific complex centered on <i>Primula</i> modesta Bisset & S. Moore (including P. ajanensis E. A. Busch, P. fauriei Franchet, P. kawasimae H. Hara, and P. matsumurae Petitmengin) from the complex centered on <i>P. borealis</i>. These show morphological similarities; they differ in chromosome number. No recent comprehensive systematic work has been done on the North Pacific representatives of sect. Aleuritia; molecular and morphometric analyses may help clarify phylogenetic relationships and taxonomy of these taxa.</p>
