 Modern genetic analyses by the Angiosperm Phylogeny Group researchers has confirmed its basal position among flowering plants.In addition, the Nymphaeaceae are more genetically diverse and geographically dispersed than other basal angiosperms.Nymphaeaceae is placed in the order Nymphaeales, which is the second diverging group of angiosperms after "Amborella" in the most widely accepted flowering plant classification system, APG IV system.
