 as varieties of C. Oxyacantha belong to the following 

 species. Even the varieties enumerated above are by 

 some botanists not considered true C. Oxyacantha, but 

 referred to C. media, Bechst., a hybrid between this 

 and the following species; the existence of hybrid forms 

 makes the distinction between the two species still 

 more difficult.
