Chromosome numbers (2n) of 14 adventive plant species from the families Apiaceae, Campanulaceae, Caryophyllaceae, Convolvulaceae, Geraniaceae, Lamiaceae, Malvaceae, Onagraceae, Poaceae, Polygonaceae, and Rosaceae are reported based on the material collected in the Republic of Altai. To determine chromosome number (ploidy level), the method of direct counting was used. Among species studied, chromosome numbers for Anethum graveolens (2n = 22), Myosoton aquaticum (2n = 28), Epilobium hirsutum (2n = 36), and Fagopyrum esculentum (2n = 16) were first examined for Russia; for Silene dichotoma (2n = 24), Ipomoea purpurea (2n = 30), and Sorbaria sorbifolia (2n = 36) – first for Siberia; for Erodium cicutarium (2n = 40) – for West Siberia; Campanula rapunculoides (2n = 68, 102), Nepeta cataria (2n = 34), Malva pusilla (2n = 42), Dianthus deltoides (2n = 30), and Echinochloa crus-galli (2n = 54) were first studied for the Republic of Altai. General distribution and the history of floristic findings of these species in the Republic of Altai are given. Previously published data on chromosome numbers from Russia are cited.
