The Lemon Tree (by the scientific name of Citrus Lemon), belongs to the Rutaceae family of Citreae tribe. All members of the tribe have a characteristic fruit, the hesperidio, a type of yellow berry in which the skin is not detached from the flesh.
Besides the lemon tree, the Citric and the Votriokarpo also belong to this tribe. The origin of lemon goes back to Central India, where the first trees were cultivated. It is a cultivated hybrid derived from wild species, such as Citric and Mandarin.
The tree can reach up to 6 metres in height, but they are usually shorter. The branches of the lemon tree have thorns and the leaves are green and shiny. The flowers are white externally but tend to be purple internally.
