Cover illustration: Extensive observations were carried out in wild populations and a large number of specimens of Codonopsis, which has long been controversial in circumscription. The authors counted chromosome numbers of Codonopsis subg. Pseudocodonopsis (mitotic metaphase and karyotype shown down right), subg.
