The ninth part of the series on the distributions of vascular plants in the Czech Republic includes grid maps of 83 taxa in the genera Aphanes, Buglossoides, Calamagrostis, Carex, Cerastium, Chenopodium, Corynephorus, Crypsis, Dorycnium, Equisetum, Marrubium, Montia, Oxalis, Pilosella, Pteris and Spergula. These maps were produced by taxonomic experts based on examined herbarium specimens, literature and field records. The plants studied cover various taxonomic and ecological groups. Habitat specialists are represented by Calamagrostis pseudophragmites, which is confined to river banks and gravel bars, Calamagrostis stricta, a species of fens and wet meadows, and the obligate halophyte Crypsis aculeata. Almost half the studied species are on the national Red List. Two of the subspecies of Spergula arvensis, namely subsp. linicola and subsp. maxima, have been extirpated from this country. Cerastium subtetrandrum, which was discovered on verges of motorways and main roads in Bohemia, is reported here as a new alien species in the Czech Republic. Three other mapped taxa have only recently been discovered in this country. Calamagrostis rivalis had been considered an endemic species of Saxony in Germany until it was discovered in Bohemia. The previously neglected Carex depressa subsp. transsilvanica was found at a few sites in eastern Moravia. A single plant of Pteris cretica was discovered in an inner wall of a castle well in central Moravia. 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 electronic appendices. The maps are accompanied by comments that include additional information on the distribution, habitats, taxonomy and biology of the taxa.
