Notes: Section Borealia is a large and polymorphic group with comparatively few taxa reported from the North Atlantic regions but very many from northern Siberia and the North Pacific regions. There is probably no way at present to efficiently compare and evaluate the species reported from different regions by Tzvelev and Yurtsev (PAF proposal). Brouillet (2006a) included all the many reported North American and Greenland microspecies in his concept of Taraxacum ceratophorum, whereas Tzvelev and Yurtsev consider this species Eurasian, barely reaching Alaska.
Several Fennoscandian species that reach or approach the Arctic where omitted from the Tzvelev-Yurtsev PAF proposal: T. hjeltii, T. murmanicum, T. norvegicum, T. simulum, and T. tornense. They are provisionally included in the T. ceratophorum aggregate. Two Russian species have not been assigned to aggregate.
