||The main aim of the project is to carry out thorough taxonomic, nomenclatural and chorological revision of diversity of vascular plants of Slovakia. New checklist of taxa will be published as an important reference source not only for botanists and other fields of science dealing with vascular plants, but also for legal issues, nature conservation, agriculture and forestry. The revision will critically respect all the actual data on the flora of Slovakia as well as latest discoveries in plant phylogeny and taxonomy. The checklist will be compatible with the current Euro-Mediterranean checklist (Euro+Med PlantBase) and other international standards. Within the project, numerous nomenclature issues will be dealt with that will result also in papers published in international journals. Web portal created for the new checklist will be a single access point not only for the information on accepted plant names and synonyms, but also for the vernacular names, and other data.
