Notes: According to Petrovsky (1999), Papaver gorodkovii is a species of uncertain affinity, disjunctly distributed on Wrangel Island, the Chukchi Peninsula, and in coastal northern Alaska. Kiger and Murray (1997) accepted North American presence, confirmed by us. Papaver gorodkovii mostly occurs in damp sites, often close to the sea.
AFLP data indicate that the predominantly diploid P walpolei is closely related to the polyploid P. gorodkovii. This is also supported by morphology, especially by the short and very dark green leaves with few, strap-shaped and subobtuse lobes, small flowers with petals white, pale yellow, or very rarely pale pink (var. roseolatum V.V. Petrovsky), and the comparatively few stamens. Before the description of P. gorodkovii in 1973, the Wrangel Island plants were assigned to P. walpolei. Tolmachev (in schedis) used the combination P. walpolei var. asiaticum when referring to what we now call P. gorodkovii. The capsule differs appreciably from that of P. walpolei in being very short obconical, sometimes as broad as long, and densely covered by black hairs. The AFLP data further indicate that P. gorodkovii may be heterogeneous and with a connection to P. cornwallisense.
