Description Neophytic wall flora in the Czech Republic was studied using 935 phytosociological relevés recorded by different authors on wall habitats. In comparison with other habitat types in the country, high number of neophytes (14%, counted from 479 species of vascular plants) was recorded on walls. Most of them occur only accidentaly with low frequency. The most frequent neophytes are Conyza canadensis, Corydalis lutea and Cymbalaria muralis. Regarding different modes of introduction, the highest number of neophytes was introduced deliberately into the country (74%). These species are mainly ornamental plants following by medicinal plants and woody species used for landscape planning. With regard to the invasive status, the most of neophytes recorded on walls belong to invasive species (40%), less often naturalized species and casuals are represented (34% and 26%). To the most frequent invasive neophytes belong common ruderal plants with good dispersal potential (e.g. Conyza canadensis, Epilobium ciliatum, Erigeron annuus and Solidago canadensis) together with woody ornamental species (e.g. Ailanthus altissima, Lycium barbarum, Robinia pseudacacia and Syringa vulgaris). New neophytes for the Czech Republic recorded on walls are ornamental plants Artemisia nitida, Campanula carpatica, Parthenocissus tricuspidata and Pseudofumaria alba.
