Genus Corydalis s. l. (Papaveraceae) in the flora of Ukraine: wild and cultivated taxa and the success of naturalization of alien species

Taxonomic composition of native and alien plants the genus Corydalis s. l. in flora Ukraine has been analyzed. Based on literature, herbarium, inventory other information, it was established for first time that 3 taxa (outside natural ranges) 16 were recorded among ergasiophytes botanical gardens dendrological parks Ukraine. The majority these (73.7 %) have not preserved collections living plants, indicating a low level naturalization. leading scientific center plant cultivation, where 82.4 % cultivated, is M. Gryshko National Botanical Garden Academy Sciences (Kyiv). Additionally, 4 at different stages naturalization noted spontaneous These include ephemerophyte C. bracteata, colonophyte lutea, epecophyte cava subsp. marschalliana range) hemiagryophyte caucasica. In conditions Syretsky Dendrological Park (Kyiv) ontogenetic structure coenopopulations solida introduced naturalized caucasica found. It found belong to mature or aging types; marshalliana – young type; with bias towards an invasive type. highest density high seed germination various coenotic conditions, which emphasizes nature this species, distinguish Its expansion corresponds existing trend spread species from southern regions, intensified by Global Climate Change. Due activity caucasica, taxon, according recommendations, should be considered as initial stage expansion, so recommended introduction countries prevented spreading
