, giving rise to the common names "cinnamon bark", "wild cinnamon", and "white cinnamon".

"Canella", the diminutive of the Latin canna, a cane or reed, was first applied to the bark of the old-world tree Cassia, Cinnamomum aromaticum, from the form of a roll or quill which it assumed in drying, and was later transferred to the West Indian tree. The species epithet winterana is an artifact from a period when this plant was confused with Winter's Bark, Drimys winteri
Drimys winteri
Drimys winteri , or Canelo, is a slender tree, growing up to 20 m tall. It is native to the Magellanic and Valdivian temperate rain forests of Chile and Argentina, where it is a dominant tree in the coastal evergreen forests. It is found below 1200 meters between latitude 32° south and Cape...

Distribution

Canella is widely distributed, and not uncommon on the Florida keys, where it was first discovered by J. L. Blodgett. It generally grows under the shade of larger trees in dense forests composed of Sideroxylon
