Temperate inland salt marshes, formerly used as meadows or pastures, are priority habitats in Europe and are threatened by intensifying anthropogenic activities. They are particularly important because of their biogeographical location on the North German Plain, which is the westernmost hotspot of continental halophytic vegetation in Eurasia. In spite of their remarkably long history of floristic research, there are disproportionately few studies dealing with plant communities. They are traditionally included in the Puccinellion maritimae and Armerion maritimae alliances with a typical distribution along the North and Baltic Sea coasts. The similarity with other inland salt marshes has been overlooked. We surveyed natural and secondary sites with euhalophytic vegetation in central Germany (Saxony-Anhalt and Thuringia) in 2018 and 2020 and analysed 105 phytosociological relevés. This resulted in the identification of three main groups (alliances) containing seven associations: annual hypersaline succulent communities of the alliance Therosalicornion (Salicornietum europaeae, Halimioni pedunculatae-Puccinellietum distantis, Suaedetum maritimae), wet saline meadows of the alliance Juncion gerardi (Triglochino maritimae-Glaucetum maritimae, Scorzonero parviflorae-Juncetum gerardi variant with Glaux maritima) and saline short-grass swards of the alliance Puccinellion limosae (Puccinellietum limosae, Atriplex prostrata community). For each association we defined the typical species composition and calculated Ellenberg indicator values depending on the ecological gradients of soil salinity, nutrients and moisture. To determine possible floristic similarities between the inland and coastal salt marshes, we compared our data with data from other areas of saline vegetation: the southern Baltic Sea coast, Kujawy (Poland), Pannonian Basin (Hungary) and Transylvanian Basin (Romania). We concluded that the salt marshes in inland Germany showed a stronger relation with salt marshes of the remote Pannonian and Transylvanian Basins, and they were well separated from the Baltic salt marshes. Thus, we suggest including inland salt marshes on the North German Plain into the syntaxonomical class of continental halophytic vegetation of Festuco-Puccinellietea.

A complete list of all alien taxa ever recorded in the flora of the Czech Republic is presented as an update of the original checklist published in 2002. New data accumulated in the last decade are incorporated and the listing and status of some taxa are reassessed based on improved knowledge. Alien flora of the Czech Republic consists of 1454 taxa listed with information on their taxonomic position, life history, geographic origin (or mode of origin, distinguishing anecophyte and hybrid), invasive status (casual; naturalized but not invasive; invasive), residence time status (archaeophyte vs neophyte), mode of introduction into the country (accidental, deliberate), and date of the first record. Additional information on species performance that was not part of the previous catalogue, i.e. on the width of species’ habitat niches, their dominance in invaded communities, and impact, is provided. The Czech alien flora consists of 350 (24.1%) archaeophytes and 1104 (75.9%) neophytes. The increase in the total number of taxa compared to the previous catalogue (1378) is due to addition of 151 taxa and removal of 75 (39 archaeophytes and 36 neophytes), important part of the latter being the reclassification of 41 taxa as native, mostly based on archaeobotanical evidence. The additions represent taxa newly recorded since 2002 and reported in the national literature; taxa resulting from investigation of sources omitted while preparing the previous catalogue; redetermination of previously reported taxa; reassessment of some taxa traditionally considered native for which the evidence suggests the opposite; and inclusion of intraspecific taxa previously not recognized in the flora. There are 44 taxa on the list that are reported in the present study for the first time as aliens introduced to the Czech Republic or escaped from cultivation.

Hybridization between native and alien congeners may pose a serious threat to biodiversity and negatively affect native flora. Here we study Solidago ×niederederi, which originated and became established in Europe as a result of a cross between the alien S. canadensis and native S. virgaurea. The recent increase in the number of records of S. ×niederederi in Europe has highlighted the need to monitor its occurrence, spread and behaviour. In the present study, we tested the effectiveness of flow cytometry for detecting hybrid plants of S. ×niederederi. Sequences of the ITS region of nrDNA and the rpS15-ycf1 spacer of cpDNA were used to confirm the hybrid origin of analysed plants and to identify the maternal species. Our study included 60 single-species populations of S. canadensis, S. gigantea and S. virgaurea, and 16 mixed populations with the presence of hybrid S. ×niederederi sampled from six countries in central Europe and adjacent areas. All individuals of S. canadensis, S. ×niederederi and S. virgaurea investigated were diploid (2n~2x~18) but differed in their relative DNA content values. The DNA content of S. ×niederederi was intermediate between S. canadensis and S. virgaurea with no overlaps, with the differences between the species being statistically significant. Therefore, we conclude that flow cytometry is a reliable and efficient method for detailed screening for hybrids within mixed Solidago populations and for identifying non-flowering or morphologically ambiguous Solidago plants. Since both parental species varied only negligibly in their DNA content, it may also be applicable across a broader geographic scale. Genetic, flow cytometric and distributional data suggest that the hybrids are to a large extent early generation (likely F1) hybrids as very few cases of supposed introgressants were also inferred. The results from chloroplast rpS15-ycf1 spacer showed that hybridization has occurred in both directions.
