Abstract
Chromosome numbers (2n) in 10 invasive plant species from the families Apiaceae, Asteraceae, Brassicaceae, Caryophyllaceae, Fabaceae, Lamiaceae, Poaceae and Urticaceae are reported on the samples collected in the Republic of Altai. Among them, chromosome complements were first examined in Asian part of Russia for Lapsana communis (2n = 14). Saponaria officinalis (2n = 28) and Lotus corniculatus (2n = 24) were studied first from Siberia. Six species: Conium maculatum (2n = 22), Bunias orientalis (2n = 14), Vicia hirsuta (2n = 14), Leonurus quinquelobatus (2n = 18), Digitaria ischaemum (2n = 36) and Setaria pumila (2n = 36), were studied first from the Republic of Altai. The most studied species are diploids. General distribution and the history of floristic findings of these species in the Republic of Altai are given. Previously published data on chromosome numbers based on the material from Russia are cited.

Chromosome numbers (2n) in 10 invasive plant species from the families Apiaceae, Asteraceae, Brassicaceae, Caryophyllaceae, Fabaceae, Lamiaceae, Poaceae and Urticaceae are reported on the samples collected in the Republic of Altai
This paper provides an information about 10 species that are most active in the republic, seven of which are included in the list of invasive or potentially invasive species of Siberia (Ebel et al, 2014)
Chromosome numbers of 39 invasive species distributed in the Republic of Altai were examined
Summary
Chromosome numbers of invasive and potentially invasive species in the flora of the Republic of Altai. Chromosome numbers (2n) in 10 invasive plant species from the families Apiaceae, Asteraceae, Brassicaceae, Caryophyllaceae, Fabaceae, Lamiaceae, Poaceae and Urticaceae are reported on the samples collected in the Republic of Altai. The information on the history of floristic studies of examined species in the territory of the Republic of Altai is provided here. The same chromosome number has been previously reported for the Republic of Crimea (Rostovtseva, 1982) and Novosibirsk Region (Krasnikov, Lomonosova, 1990; Krivenko et al, 2013).
