Several other reports of octoploids from western Greenland and northeastern Canada probably belong to this species.
Geography: North American (NE): CAN GRL.
Notes: Papaver labradoricum is known from eastern Canada, southern and western Greenland, and also from one alpine locality (CAN) in eastern Greenland. The species belongs, both in morphology and in AFLP markers, close to a Beringian and Cordilleran group of species, most closely with P. detritophilum (see below). Its range in Canada reaches north to northern Baffin Island and west to Bathurst Inlet. Farther west it is replaced by the hexaploid and octoploid P. hultenii, belonging in the same AFLP affinity.
Papaver labradoricum generally resembles P. radicatum and P. lapponicum morphologically. The majority of authors have accordingly assigned it as a subspecies of P. radicatum, whereas Knaben (1959a, 1959b) assigned it to P. lapponicum on the basis of its octoploid chromosome number. The similarity is, however, superficial. In several morphological details (most distinctly in its strongly dentate hairs), P. labradoricum deviates from P. lapponicum and P. radicatum (Solstad 2009). These results are supported by the low fertility found by Knaben (1959b) in crosses between P. labradoricum on one hand and P. lapponicum and P. radicatum on the other hand (at the level of fertility for crosses between species according to Knaben).
