The paper presents new records of 24 vascular plant species from 11 Eurasian countries. One taxon (Orobanche laxissima) is reported from Armenia; one (Epipactis condensata) from Azerbaijan; two (Phragmites americanus, Polygala multicaulis) from Belarus; one (Stipa caucasica) from Egypt; one (Puccinellia hauptiana) from Kyrgyzstan; three (Aquilegia xinjiangensis, Geranium saxatile, Ranunculus songaricus) from Mongolia; one (Stipa roborowskyi) from Pakistan; three (Echinochloa muricata, Erigeron acris subsp. podolicus, Hypericum majus) from Poland; six from Russia, whereof one (Zanthoxylum armatum) from the European part of Russia and five (Chaerophyllum aureum, Elsholtzia densa, Poa compressa, Ranunculus subrigidus, Viola sororia) from the Asian part of Russia; two (Ludwigia repens, Sagittaria latifolia) from Slovakia; and three (Rubus ambrosius, Rubus camptostachys, Rubus perrobustus) from Ukraine. For each species, synonyms, general distribution, habitat preferences, taxonomy with remarks on recognition and differentiation of the species from the most similar taxa occurring in a given country, as well as a list of recorded localities (often far from the previously known areas), are presented.
