AbstractA revision ofTaraxacumsect.PalustriaDahlst. is given; 48 species are dealt with, of which 29 are new; the descriptions of the latter partly have been borrowed from comments and provisional descriptions by Dahlstedt and Haglund, found in herbaria.T. lividum(Waldst.&Kit.) Petermann,T. tenuifolium(Hoppe) Koch andT. udumJord., so often and for so many years hidden in the lists as synonyms, are considered to be good species. The area of distribution, in a broad sense, covers the central part of Europe with an offshoot extending into Asia Minor. Due to agronomical measures the rich vegetations formed in the past by species of the section have sometimes dwindled considerably; some species even seem to have died out.
