| Publ. & Syn. | Sam., Bot. Not. 1922: 260 (1922). Lectotype (LE): European Russia: "Novaja Semlja, Grebovaja fiord", 02. Sept. 1921, leg. B. Lynge (Tzvelev 2007b: 252). - Epilobium davuricum subsp. arcticum (Sam.) P.H. Raven, Feddes Repert. 79: 61 (1968). |
| Notes | Elven, Solstad, and Murray: Skvortsov (1980a, PAF proposal) synonymized Epilobium arcticum with E. davuricum. Raven and Hoch (in comment, unpublished data) accepted E. arcticum apart from E. davuricum. They found E. arcticum, E. davuricum, and E. palustre to be three non-overlapping species. We support that conclusion from experience with all three species from several regions. Hoch (unpublished data, in comment) considered E. arcticum restricted to North America: northern Alaska, mainland parts of the Northwest Territories and Nunavut, the Canadian Arctic Archipelago, and Greenland north of 70N. The species was, however, originally described from "Groenlandia, Nova Zemblia, insula Waigatsch et Sibiria arctica". Samuelsson (1922) cited and illustrated specimens (syntypes) from all the mentioned areas. His illustrations clearly show E. arcticum. We have seen good material of the species in the field in northeastern Siberia (the Lena River region) and Chukotka, besides North America. This is a nearly circumpolar, high arctic species. |
