(2n = 16), and Genista tinctoria L. (2n = 48) - from Asian Russia; for Calendula officinalis L. (2n = 32) and Rudbeckia hirta L. (2n = 38) - from Siberia. Chromosome numbers on the material from the Novosibirsk Region were revealed for the first time for Lapsana communis L. (2n = 14) and Silene noctiflora L. (2n = 24). 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.

We continue the karyological study of adventive species in the flora of the Novosibirsk Region (An'kova, Zykova, 2020, 2021; Zykova, Pankova, 2021; Zykova et al., 2022a). In this paper, we present the results for 12 species found in the Novosibirsk Region. Among them, Dracocephalum thymiflorum and Veronica filiformis are invasive species in the region, whereas Asclepias syriaca, Lapsana communis, and Silene noctíflora are potentially invasive (very active in other regions). The most species spread at various times from sites of introduction with the exception of Lapsana communis, Silene noctíflora, and Dracocephalum thymiflorum which are unintentionally entered.
Chromosome numbers were counted by direct observation in metaphase in root meristem squash preparations according to the method used by Zykova and Pankova (2021). Metaphase plates were observed under 100x magnification of the Axioscope 40 (Karl Zeiss, Axio Lab) microscope and photographed with an AxioCam MRc 5 digital camera. For all species, literature references on chromosome numbers known on material collected in Russia are given. Latin names of plants are provided according to the "Catalog of Life" (Hassler, 2023). Voucher specimens have been deposited to the Herbarium of the Central Siberian Botanical Garden SB RAS (NS, Novosibirsk).
Apocynaceae
Asclepias syriaca L., 2n = 22
"Novosibirsk Region, Novosibirsk District, environs of Akademgorodok, mixed forest, adjacent to the old exposition areas of the Central Siberian Botanical Garden. 27 IX 2020. E. Zykova, Z894-2020" (NS0045583).
Distribution: The native area of Asclepias syriaca covers North America and adjacent areas of Canada. It was previously experimentally cultivated as a rubbery species and now is used as ornamental and melliferous plant. The species has widely settled in the countries of Central and Southern Europe, where it is prohibited for cultivation (Asclepias syriaca, 2023). In Siberia, it was first found outside of culture in the Altai Territory (Terekhina, 1998). Recently discovered in the Novosibirsk Region and the Republic of Altai (Ebel, Zykova, 2022).
The chromosome number was determined for the first time in Russia. The same chromosome number was reported for some countries of Eastern Europe (Rice et al., 2015).

Distribution: Mediterranean species widely cultivated all around the world. In the Novosibirsk Region, it was recorded in the Novosibirsk agglomeration (Zykova, Shaulo, 2020, 2021; Zykova et al., 2022b). However, as the species easily spreads from cultivated sites, it can be found in other districts of the region.
This is the first report of the chromosome number for Siberia. The same number is determined for the Primorye Territory (Probatova, 2014, and references therein).

This is the first report of the chromosome number for the Novosibirsk Region. The same chromosome complement has been published earlier from the Republic of Karelia and the Leningrad Region (Probatova et al., 2009), the Republic of North Ossetia-Alania (Probatova, Seledets, 2008), the Krasnodar Territory (Probatova et al., 2013), and from the Republic of Altai (Zykova et al., 2020).

Conclusion
The study provides the first records of chromosome numbers for 12 alien species based on the material from the Novosibirsk Region. Most species are diploids. Three species are tetraploids: Calendula officinalis, Genista tinctoria, and Sorghum drummondii. Our data correlate with data on chromosome numbers determined on the material from the regions of East Siberia, the Far East, and European Russia.
