Within the last few years considerable interest has been generated in the use of cytological characters for assisting in taxonomic treatments of the Composite species Chrysanthemum leucanthemum L. sensu lato. This species is extremely variable and numerous infra-specific taxa have long been recognised. Recent works (see following text) using North American and Continental material have suggested that there might be sufficient grounds for splitting up the species aggregate into specific taxa corresponding to chromosome races.
