Studies on the chromosomes of Chelidonium majus L: III. Variation of karyotypes found in plants coming from different localities

In the previous papers we have reported that the chromosome number of Chelidonium majus was 2n=10, instead of 2n=12, the number hitherto determined in the European race. Recently we found some variations of the karyotype in the material plants which were collected in different localities. The results obtained from the morphological comparison of the somatic chromosomes in these plants were described in the present paper. The karyotypes and their diagrammatic representations are shown in Figs. 1 and 2 on the pages 61 and 62.
