(2) 36 (4x). - Far East (N), Alaska. - Several reports.
(3) 54 (6x). - Siberia (Yakutia). - Krogulevich and Rostovtseva (1984).
Geography: Asian (NE) - amphi-Beringian: SIB RFE ALA CAN.
Notes: Kelso: There are two and only two arctic species, well distinguished by homostyly vs. heterostyly (plus some supporting other morphology, Kelso 1987a). The name Primula tschuktschorum applies to the very narrowly distributed Beringian species (the Chukchi Peninsula, St. Lawrence Island, the Seward Peninsula). The treatments and maps of Hultén (1968a, 1968b) are erroneous as he focused on size alone and not on, e.g., homostyly vs. heterostyly.
