Chromosome numbers in some alien plant species of the Novosibirsk Region: post VI

This paper presents the chromosome numbers (2n) for 14 alien species from the families Apiaceae, Apocynaceae, Asteraceae, Boraginaceae, Fabaceae, Lamiaceae, Poaceae, Plantaginaceae, Violaceae collected in the Novosibirsk Region. For Apocynum cannabinum (2n = 16), Clinopodium acinos (2n = 18), Veronica agrestis (2n = 14), V. verna (2n = 16), Viola × wittrockiana (2n = 46), chromosome numbers were determined for the first time on the material from Russia; for Daucus carota (2n = 18), Heracleum sosnowskyi (2n = 22), Arrhenatherum elatius (2n = 28) – from Asian Russia; for Kalimeris incisa (2n = 18) – from Siberia. Chromosome numbers on the material from the Novosibirsk Region were revealed for the first time for Myosotis sparsiflora (2n = 18), Lupinus polyphyllus (2n = 48), Hordeum jubatum (2n =28), Veronica persica (2n = 28). For all the species studied, brief notes on their general distribution and dispersal in the Novosibirsk Region are provided, along with literature data on chromosome numbers from other regions of Russia.
