Abstract
Seven new species of Taraxacum from the countries
of northern Europe are formally described and discussed, and their
known distribution is presented. Three of them (T. expandens,
T. finitimum, T. obnuptum) belong to T.
sect. Borea, the rest (T. broddesonii, T.
huddungense, T. pilosella, T. theodori) are members of T.
sect. Ruderalia. Three of the species have been
known and named for a very long time, yet not formally described by
earlier taraxacologists. T. obnubilum Dahlst. ined.
(non Dahlst. ex Puol.) is described with a new name.
Key words: Compositae, dandelions,
