There are 18 species in spring synusiums in the broadleaf forests of the north-eastern Ukraine. The coenotic role of species of genus Corydalis Vent. in composition of these synusiums was shown. Its role is the greatest on Polissia. There is a low total number of species on the releves. The number and the average projective coverage of all species of sinusiums are higher in the Foreststeppe. The most widespread species of genus Corydalis is C. solida (L.) Clairv. On north-east of Ukraine C. marschalliana (Pall. ex Willd.) Pers. and C. cava (L.) Schweigg. & Körte. are on verge of natural areal. C. cava has higher coenotic role that prevails more often on the different landscape especially on Polissia. Fourth species of genus – C. intermedia (L.) Mérat is widespread sporadically and has the greatest coenotic role on the loess plateau of Polissia.
