Although originating from the same
parent species as Citrus aurantium, the actual parents were different
varieties to those of Citrus aurantium. There are clear records of
Citrus sinensis in China only by the 1100's and in India by the 1300's.
By the 1400's it had spread to the Mediterranean. From the mid 1600's
onwards, European colonists spread it around the world's tropical regions.
The Navel variety originated in Bahia, Brazil in the 1800's.
