It is also called sweet orange, to distinguish it from the related "Citrus × aurantium", referred to as bitter orange. The sweet orange reproduces asexually (apomixis through nucellar embryony); varieties of sweet orange arise through mutations.

The sweet orange has had its full genome sequenced. Sweet oranges were mentioned in Chinese literature in 314 BC. , orange
