+ Crataegomespilus Simon-Louis ex Bellair

This name covers any graft hybrid between Mespilus and Crataegus. Such plants are chimaeras, containing tissues of both parental species, and tend to be unstable. Early examples resulted from the practice of grafting M. germanica onto a C. monogyna rootstock (+ Crataegomespilus dardarii). More recently, experimental graft hybrids have been made between M. germanica and C. × media ‘Kermesina Plena’ (+ Crataegomespilus potsdamiensis). Sexual hybrids between Mespilus and Crataegus belong in × Crataemespilus (q.v.), although the two are sometimes confused in listings.
