Based on the cladistic analysis by Anderberg (1994a) Enkianthus seems to have originally been shrubs with deciduous leaves, racemose
inflorescences, camp anulate corollas, and winged seeds, whereas the more derived species possess coriaceous leaves, umbellate inflorescences, flowers with tubular or urceolate corollas, and unwinged seeds.
Very often the upper flowers of a racemose
inflorescence will not attain full development, leading to a partial sterilization of whorls.
