| Notes | Polemonium acutiflorum approaches the Arctic also in Norway. Tzvelev (1980b, comments) distinguished between P. acutiflorum and P. campanulatum and reported the latter from, e.g., the Murman area, the Bolshezemelskaya Tundra, the lower Ob River, the Gydan Tundra, the lower Jenisei and Kolyma rivers, and the Chukchi Peninsula, all of these regions generally within the range he also reported for P. acutiflorum. He considered P. campanulatum to be a hybrid species from P. acutiflorum x P. caeruleum (the latter species absent from the majority of regions above). Sekretareva (1999) accepted it as P. x campanulatum. This hybrid hypothesis is highly improbable from Nordic evidence. Polemonium caeruleum and P. acutiflorum are allopatric in Fennoscandia and without documented intermediates, and P. campanulatum was described from the parts of northern Fennoscandia where P. caeruleum is absent. Polemonium campanulatum should be synonymized with P. acutiflorum as indicated also by its range. Plants from northern Fennoscandia do not differ from those from Chukotka, Alaska, or northwestern Canada and must go by the same name. Petrovsky: Polemonium campanulatum is just large P. acutiflorum. |
