The thirteenth part of the series on the distributions of vascular plants in the Czech Republic includes grid maps of 88 taxa in the genera Alcea, Ambrosia, Anacamptis, Anchusa, Anoda, Atocion, Ballota, Bothriochloa, Bunias, Conium, Epipogium, Kickxia, Kitaibela, Lavatera, Lawrencia, Limodorum, Listera, Malope, Malva, Neotinea, Nonea, Nuphar, Nymphaea, Peucedanum, Phlomis, Selinum, Sida, Silaum and Silene. These maps were produced by taxonomic experts based on examined herbarium specimens, literature and field records. Particular attention was paid to rare and declining species. Altogether, 34 of the mapped species are on the national Red List. Critically threatened species, with the highest rates of decline and smallest population sizes, are mainly among orchids and aquatic plants. Two species, Anacamptis coriophora and Peucedanum arenarium, have been extirpated from this country and are classified as nationally extinct. In contrast, four of the mapped species have only recently been identified as new aliens to the Czech flora: Kitaibela vitifolia, Lavatera punctata, Silene csereii and S. stricta. Based on the analysis of the past distributions and circumstances of the earliest records, Silene bupleuroides and S. conica are proposed for reclassification from native to casual neophytes. Altogether, 47 archaeophytes and neophytes are discussed. Two of the neophytes, Ambrosia artemisiifolia and Bunias orientalis, have become invasive and at present they are widespread mainly in warm areas of the country. Spatial distributions and often also temporal dynamics of individual taxa are shown in maps and documented by records included in the Pladias database and available in the Supplementary materials. The maps are accompanied by comments that include additional information on the distribution, habitats, taxonomy and biology of the taxa.
