| Taraxacum inventories in several meadows all over the Netherlands seem to indicate that a less varied management involves a decrease in total number of dandelions as well as a decrease in number of species. Taraxacum species can be classified in a range from more to less dynamic habitats. T. nordstedtii is the last species to disappear, T. adamii the last but one. The distribution of Taraxacum (sect. Vulgaria) species in semi-natural grasslands gives some indication about the causes of the qualitative decrease. It is still doubtful whether certain species or combinations of them should be considered as characteristic of certain forms of management. |

| Description of Taraxacum vansoestii Hagendijk, Oosterveld et Zevenbergen, spec. nov. The species is only known from the island of Terschelling, the Netherlands, out of the transition zone from sand dunes to saltmarsh. The taxonomic position of the new species, which shows affinities to quite different sections of the genus Taraxacum (viz. sect. Obliqua. \ sect. . Erythrosperma,: sect. Palustria and sect. Vulgaria) is discussed. The authors give arguments for a possible position in the group Dissimilia of the section Erythrosperma. |
