7    <p>The fruit of the Citrus × sinensis is considered a sweet orange, whereas the fruit of the Citrus × aurantium is considered a bitter orange. The sweet orange reproduces asexually (apomixis through nucellar embryony); varieties of sweet orange arise through mutations.</p>

Clementines can be separated into 7 to 14 segments. Similarly to tangerines, they tend to be easy to peel.</p>
