| Pyrola grandiflora Radius | |
| Publ. & Syn. | Radius, Pyrola & Chimophila: 27 (1821). Described from Labrador (Canada). - Pyrola rotundifolia var. grandiflora (Radius) Fernald ex A.P. Khokhr., Sosud. Rast. Sovet. Dal'nego Vostoka 5: 162 (1991). |
| Chromosomes | (1) 26 (2x). - Europe, Russia (N, W), Far East, Canada (W). - Numerous reports. Diploid in FCM, Mirré (2004, 48 plants, Iceland, Austria, southern Siberia, Japan, East Chukotka, southern Alaska, British Columbia, northwestern U.S.A.). (2) 3x. - Europe (Iceland, Faeroes), Far East (N), Alaska. - Triploid in FCM, Mirré (2004, five plants, together with diploids and tetraploids). (3) 52 (4x). - Europe (N, C, S), Far East (N), Alaska, Canada, U.S.A. (NE), Greenland. - Numerous reports. Tetraploid in FCM, Mirré (2004, 120 plants, Jan Mayen, Iceland, Faeroes, the British Isles, Norway, Austria, the Caucasus, northern Russia, northern Siberia, Alaska, Canada, Greenland). The European diploid counts (possibly except for a Kolguev one) belong to Empetrum nigrum s. str., the Pacific ones probably to other taxa if such ones are recognized. The arctic amphi-Atlantic tetraploid counts probably belong to E. hermaphroditum, the non-arctic European ones to plants traditionally considered as E. hermaphroditum but more similar to E. nigrum s. str. in molecular markers, and the others (Asian, western North American) to plants more different from E. nigrum s. str. in molecular markers. |
