• Ranunculus silerifolius var. silerifolius and var, glaber were cyto-logically examined. The karyotypes observed in var, silerifolius were classified into four different types, Matsuyama, Mugi, Otaru and Karatsu, as found in var. glaber. The F1 plants between var. silerifolius and var, glaber, both of which have the same karyotype, showed the silerifolius-type in external morphology and their meioses were normal. The features of F2′s were variable as seen in the field. Hence, it may be concluded that the external morphological variation occurred independently of the chromosomal variation, which played an prominent role in the intraspecific differentiation of R. silerifolius.
