Cytological studies in Ranunculaceae

IV. The karyotype analysis in Actaea and some other genera

Abstract

1. The karyotypes of five species and one variety are determined as follows:
Actaea asiatica K(2n)=16=6A^m+2^csB₁^m+2^csB₂^sm+2C^sm+2D^m+2E^st
Adonis amurensis K(2n)=24=12A^m+10B₁^st+2^tB₂^st
Anemonopsis macrophylla K(2n)=16=10A^m+2^tB^st+2C^st+2D^st
Eranthis pinnatifida K(2n)=16=8A^m+4B^st+2C^sm+2^tD^st
Trautvetteria japonica K(2n)=16=8A^m+2B^st+2C^st+2D₁^st+2^tD₂^st
Trollius Riederianus var. japonicus K(2n)=16=2A^st+4B^sm+2C^st+2^tD₁^st+6D₂^st
2. Considering from a karyotypic standpoint, Actaea asiatica presents a certain similarity to Cimicifuga simplex var. ramosa, and Anemonopsis macrophylla to diploid species of Clematis, e. g. Cl. Japonica.
