| Braya thorild-wulffii Ostenf. | |
| Publ. & Syn. | Ostenf., Meddel. Grønland 64, 6: 176 (1923). Holotype (C): Greenland: Gunnar Andersson Valley (8228'N), 11. July 1917, leg. Th. Wulff. - Braya purpurascens subsp. thorild-wulffii (Ostenf.) Hultén, Circumpolar Pl. 2: 18 (1971). - Braya pilosa subsp. thorild-wulffii (Ostenf.) V.V. Petrovsky, Fl. Arct. URSS 7: 52 (1975). |
| Chromosomes | 56 (8x, x = 7). - Europe (N), Siberia (N), Far East (N), Alaska, Canada, Greenland. - Numerous reports, some Alaskan and northwestern Canadian ones for B. henryae. A plant with 2n = 48 (probably aneuploid) was found among plants with 2n = 56 in Taimyr (Zhukova and Petrovsky 1984). Not included: A report of 2n = 64 from northeastern Greenland (Sørensen and Westergaard in Löve and Löve 1948) is explained as an error by Jørgensen et al. (1958). See also an explanation of the same number reported for B. linearis in the same source. A report of 2n = 56 (Löve and Löve 1956b) is from Iceland where the species otherwise is unknown. Jørgensen et al. (1958) suggested the report to be a fake based on their own report from northeastern Greenland. This Icelandic record belongs to a long series of improbable and later discounted reports from Iceland of species and chromosome counts by the Löves. They are often documented by vouchers (ICEL), allegedly from Iceland but probably collected elsewhere and mislabeled, and seem to have been created to strengthen either the case for Ice Age refugia in Iceland or to enhance the American element in the Icelandic flora. A report of 2n = 84 (12x) from Putorana in Siberia (Krogulevich 1976a) must be checked against voucher before acceptance. |
