| Chromosomes | (1) 14 (2x). - Russia (SW). - Petrova in Prokudin et al. (1977). (2) 21 (3x). - Europe (N). - Kiellander (1935). (3) 28 28-32 (4x). - Europe, Russia, Siberia, Far East, Canada. - Numerous reports. (4) 42 (6x). - Europe, Russia. - At least five old reports. All recent reports, with one exception, are of tetraploids (2n = 28). The hexaploid (and triploid) reports are from the period 1929-1954 and probably not vouchered. It it therefore possible that this species is predominantly or entirely tetraploid and sexual. |
