The Orange is one of the oldest of cultivated fruits. Its nativity is still in doubt, but it is probable that it is indigenous to the Indo-Chinese region. It is now widely distributed in all warm-temperate and tropical countries, in many of which it has run wild and behaves like a native plant. In parts of Florida the Orange was found wild when permanent settlements were made, but it had probably spread from stock that was introduced by the early Spaniards.
