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

Abstract

Chromosome numbers (2n) for 12 alien species (Apiaceae, Asteraceae, Brassicaceae, Campanulaceae, Fabaceae, Lamiaceae, Malvaceae, Onagraceae, Poaceae, Polygonaceae) from the Novosibirsk Region are given. For the first time for Russia, the number of chromosomes of Xanthogalum purpurascens (2n = 22) is given, for Siberia – Nepeta cataria (2n = 34), Malva pusilla (2n = 42) and Koenigia weyrichii subsp. weyrichii (2n = 20). For all studied species, short information on the general distribution and dispersal in the Novosibirsk Region, literature data on the number of chromosomes from the territory of Russia are presented.
