|discussion=<p><i>Primula tschuktschorum</i> has a long history of taxonomic confusion with its close relative <i>P. pumila</i>, from which it is distinguished by its heterostylous flowers, more delicate appearance, and lack of farina. It appears to be restricted in North America to the Bering Strait region of Alaska between the Seward Peninsula and Bristol Bay, where it grows occasionally in coastal areas and more commonly at higher elevations in the mountains around late-lying snowbanks.</p>
