TARAXACUM SECT. ERYTHROSPERMA IN SLOVAKIA III: TARAXACUM PARNASSICUM DAHLST., NEW LOCALITIES AND NOTES ON ITS DISTRIBUTION AND TAXONOMY

Abstract

The paper presents new records of Taraxacum parnassicum, the most common member of Taraxacum section Erythrosperma in Slovakia. The species has been recorded in most of the 31 phytogeographical districts of Slovakia. At least 25 new localities were discovered, and many old ones were confirmed. T. parnassicum prefers natural and semi-ruderal sites on limestone, rarely on volcanic and sandy soils, predominantly not shaded. The majority of populations occur from the lowland to supracolline vegetation belt, mainly at elevations of 140–700 m a.s.l., with the altitudinal maximum at 1,410 m a.s.l. A distribution map is given with the list of localities from the whole territory of Slovakia as well as short discussion about its taxonomy and ploidy level.
