"Cinnamon (Cinnamomum verum, synonym C. zeylanicum) is a small evergreen tree 10-15 m tall, belonging to the family Lauraceae, native to Sri Lanka and Southern India. The bark is widely used as a spice....The name cinnamon comes from Greek kinnámōmon, from Phoenician and akin to Hebrew qinnâmôn, itself ultimately from a Malaysian language, cf. Malay and Indonesian kayu manis "sweet wood"....Portuguese traders finally discovered Ceylon (Sri Lanka) at the end of the fifteenth century, and restructured the traditional production of cinnamon by the salagama caste....Dutch traders finally dislodged the Portuguese by allying with the inland Ceylon kingdom of Kandy. They established a trading post in 1638, took control of the factories by 1640, and expelled all remaining Portuguese by 1658." http://en.wikipedia.org/wiki/Cinnamon
