What are Citrus Fruits?
All the types of citrus fruits that you buy in the store or grow at home are hybrids from the 3 natural citrus fruits. The original species of citrus fruits are pomelo, mandarin orange, and citron.
Citrus is the botanical name for the genus of all fruits classified as citrus fruits. All types of citrus fruits such as oranges, lemons, limes, and grapefruits belong to the family Rutaceae. The tangy fruits in this family generally have juicy segments that are surrounded by a zesty rind.
You can easily tell which are citrus fruits and which are not by their botanical name. All types of citrus fruits will have the name citrus in it. Other tropical fruits such as pineapples, bananas, mangoes, grapes, and peaches are not citrus fruits. They belong to plant genera unrelated to citrus fruits. Other types of fruits such as pomegranate, kiwifruits, and passion fruits are not related to the Citrus genus as well.

Clementine
Clementines are seedless small citrus fruits that are related to mandarins. You can tell clementines apart from tangerines because their zesty rind is a deeper orange color.
