(Papaveraceae) in Altai and Japan*
Genjiro Ishida1)Abstract. The karyotype of Chelidonium majus L. var. majus in Altai area was compared with the karyotype of C. majus L. var. asiaticum (Hara) Ohwi in Japan. The chromosome number of C. majus var. majus in Altai area was 2n=12, and the chromosome number of C. majus var. asiaticum in Japan was 2n=10. C. majus var. majus in Altai area showed a homogeneous and symmetric karyotype, while C. majus var. asiaticum in Japan showed a low homogeneous and low symmetric karyotype.
