| Tephroserisarctisibirica (Jurtz. & Korobkov) Czerep. | |
| Publ. & Syn. | Tephroseris atropurpurea x T. palustris subsp. congesta. |
| Notes | Korobkov (1987b) mapped three localities (Tiksi, Cape Schmidt, Wrangel Island) for Tephroseris x arctisibirica and it has only been found a few places else later. We have no information about whether it forms populations. It may be little stabilized and not acceptable as an independent taxon. |
| Chromosomes | (1) 36-37 40 (2x, x = 18, 20). - Siberia, Far East (N). - At least five reports. (2) 48 (2x, x = 24). - Russia (N), Siberia, Far East (N), Alaska, Canada. - Numerous reports. Löve and Löve (1975a) included only reports of 2n = 48 for this plant. Not included: A report of 2n = 24 from western North America (Chinnappa and Chmielewski 1987) must belong to something else. |
