Discussion

Primula egaliksensis is distinguished by its relatively few-flowered inflorescence of homostylous flowers; violet (forma violacea Fernald) and white corollas are equally common and sometimes occur together within populations. Early treatments of the arctic flora confused P. egaliksensis with other species, notably P. stricta. The names P. farinosa var. groenlandica Pax and P. sibirica in the sense of Hooker (not Jacquin) refer in part to P. egaliksensis.

Morphologic and genetic evidence (A. Guggisberg et al. 2006) indicates that Primula egaliksensis is a hybrid between sects. Aleuritia and Armerina, with probable parents being P. nutans and P. mistassinica or an ancestral form of that species. The rounded, petiolate leaves and narrow capsules ally it strongly to sect. Armerina, and it has traditionally been placed in that section. Primula egaliksensis has frequently been confused with P. nutans; it differs in its smaller, homostylous flowers and the absence of auriculate bracts.
