Abstract
The hamate dandelion section (Taraxacum sect. Hamata H. Øllg.) represents a morphologically tight group of taxa, distributed in the oceanic and sub-oceanic regions of Europe. In Central Europe, it is mostly confined to freshly moist meadows, as well as places in the shade within urban areas. The known distribution area in Europe until now extended towards the E part of the Czech Republic and S Poland. During the past six years, we have discovered an additional eleven localities of hamate dandelions in NW and N Slovakia, which represents a corrected south-eastern limit for the distribution area of this section. In this paper, we discuss seven recognized taxa (T. boekmanii, T. fusciflorum, T. hamatiforme, Taraxacum hamatum, T. lamprophyllum, T. pseudohamatum, and T. quadrans). We provide a determinative key to the Slovakian hamate dandelions, brief species descriptions, comments on their distribution, a distribution map of the section in Slovakia, as well as images of all of the newly found species.
