The Taraxacum praestans aggregate | |
Publ. & Syn. | Section Crocea sensu Tzvelev. |
Notes | This section is the major one in the Arctic in the North Atlantic regions and one of the most diverse in number of named microspecies. According to Hultén and Fries (1986), it is distributed from northwestern Siberia across northern and western Europe, Iceland, Greenland, and west to Hudson Bay in Canada. It is almost absent from the PAF proposal of Tzvelev and Yurtsev and we have to fit together pieces from numerous and heterogeneous sources. As it has its assumed diversity center in northwestern Europe (including Iceland), we have tried to fit the described species into the species group below. Whereas there are good summaries of the Icelandic microspecies, there is no general summary of the Fennoscandian ones. Many named microspecies that reach the Arctic are certainly missing. Brouillet (2006a) merged the species occurring in Greenland within his Taraxacum lapponicum in his sect. Spectabilia. |
