|discussion=<p><i>Minuartia obtusiloba</i>, an amphi-Beringian species, sometimes forms hybrid swarms with <i>M. arctica</i>. Specimens labeled <i>Arenaria</i> sajanensis Willdenow ex Schlechtendal from western North America, sometimes referred to <i>M. biflora</i> (e.g., H. J. Scoggan 1978–1979, part 3), are likely to be <i>M. obtusiloba</i>.</p>
