Near-species differences:
Citrus, orange and orange are three different varieties of citrus fruits, which are easily confused because of their similar shapes. Citrus is the general name of orange, tangerine, tangerine, kumquat, pomelo and bitter orange. The names of oranges and oranges have long been confusing.
From a scientific point of view, oranges are the basic species with small flowers, easy peeling and dark green embryos. Citrus is a hybrid of orange and sweet orange. The flower is big, the fruit is not peeled like an orange, and the embryo of the seed is light green.
Therefore, in the wide-skinned citrus, orange (Gan Lu) is orange, and Wenzhou dense orange is orange, not orange. Citrus and orange belong to the same family but different species in plant taxonomy. In addition, oranges and oranges are often collectively referred to as "citrus".
