- Hultén, Ark. Bot., n. s., 7, 1: 67 (1968). Holotype (S): Alaska: Cape Beaufort, 03.-07. Aug. 1961, leg. E. Hultén.
Geography: Asian (N)? - amphi-Beringian: SIB? RFE ALA CAN.
Notes: Elven and Murray: The eglandular plants of northern Alaska and the Yukon Territory have the comparatively narrow and little dentate leaves typical of Parrya arctica. However, the sepals and anthers are distictly longer than in P. arctica but mostly shorter than in the more southern, glandular plants (subsp. nudicaulis). Eglandular plants extend south to the Seward Peninsula in western Alaska, but there often with coarsely dentate to lobed leaves and much larger flowers, and strongly glandular plants occur at least at one north coast locality (Prudhoe Bay). We interpret these aberrant plants as signs of transition, supporting rank as subspecies.
Two geographical groups of plants have been difficult to assign: those of northernmost Siberia (as subsp. nudicaulis or subsp. septentrionalis), and those of northwestern Canada, especially Victoria Island (as subsp. septentrionalis or P. arctica). The plants of southwestern Victoria Island are especially enigmatic. They combine the short petals and anthers of P. arctica with the leaf and fruit shape of P. nudicaulis subsp. septentrionalis. We here assign them to P. nudicaulis subsp. septentrionalis.
