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.

• Neophytes in Austria: Habitat preferences and ecological effects (2005, background): “In Central Europe, riparian areas show the highest number of neophytes of all natural and semi-natural vegetation types (Lohmeyer & Sukopp 1992, 2001; Pyšek et al. 2002b).”
• Catalogue of the Naturalized Flora of Taiwan (2004, background): “A naturalized species is defined as an introduced (non-native, exotic) species, that can consistently reproduce and sustain populations over many generations without (or despite) direct intervention by humans (Richardson et al., 2000; Pyšek et al., 2002, Wu et al., 2003).”
• Invaders among locals: Alien species decrease phylogenetic and functional diversity while increasing dissimilarity among native community members (2018, background): “We considered a plot invaded when it contained at least one neophyte species—of the 1,839 species, 138 were neophytes (Pyšek et al., 2012).”
• Pladias Database of the Czech flora and vegetation (2021, background): “…records (Czech National Phytosociological Database, CNPD; Chytrý & Rafajová 2003), and various databases of plant traits (e.g. CLO-PLA, Klimešová & de Bello 2009), habitat affinities (Chytrý & Tichý 2003, Sádlo et al. 2007, Prach et al. 2014) and alien species (Pyšek et al. 2002, 2012).”
• MAcroecological Framework for Invasive Aliens (MAFIA): disentangling large-scale context dependence in biological invasions (2020, background): “Given that the majority of successful alien plants are introduced through horticulture (Hanspach et al. 2008; Lambdon et al. 2008; Pyšek et al. 2012; van Kleunen et al. 2018), this phenomenon may have important consequences for macroecological patterns.”
