370117 Papaver pulvinatum Tolm.
- Tolm., Trudy Bot. Muz. 24: 269 (1932). Lectotype (LE!): Siberia: Taimyr, "Nizovya r. Yamu-Tarida (bassein Taimyrskogo ozera), raion vesnovki ekspeditsii (7427'N, 10250'E)", 05. Aug. 1928, leg. A.I. Tolmachev 135 (Elven et al. 2009: 988).
Geography: Asian (N) - Asian Beringian.
Notes: Tolmachev (1975a) recognized three subspecies of P. pulvinatum: subsp. pulvinatum in Taimyr and with one locality in the Khatanga River estuary; subsp. lenaense along the lowermost Lena River in northern Yakutia; and subsp. tschuktschorum around Chaun Bay in West Chukotka and on Wrangel Island. Petrovsky (1999) merged the Far East, mainly tetraploid subsp. tschuktschorum (including a subsp. interius he described in 1980) with the Siberian, mainly tetraploid subsp. pulvinatum. However, he accepted a mainly octoploid subsp. lenaense Tolm. in the gap between the part ranges of his subsp. pulvinatum along the lower Lena River.
Analysis of AFLP markers combined with morphology are evidence that the lower Lena River plant (subsp. lenaense) should be kept outside P. pulvinatum and preferrably as a species. Material was not available to evaluate whether P. pulvinatum subsp. pulvinatum and subsp. tschuktschorum differ genetically. We provisionally accept P. pulvinatum as a mainly tetraploid species with two major races, but excluding subsp. lenaense.
