Notes: A large number of microspecies have been described and assigned to this aggregate. No account of the 'arctic' representatives exists. A majority of the adventive (and mostly casual and/or vegetative) Taraxacum in many arctic settlements probably belong here, e.g., plants collected in southwestern Greenland and Svalbard. Brouillet (2006a) applied the name T. officinale collectively for this aggregate and mapped it from, e.g., Greenland and Nunavut. We have found records from arctic or near arctic sites of a few microspecies.
