means A South American tree whose bark contains quinine, the bitter compound that became the first effective treatment for malaria.

from Named by Linnaeus after the Countess of Chinchón, a Spanish vicereine in Peru who, legend claimed, was cured of fever by the bark and brought it to Europe in the 1600s — a charming tale historians now doubt, since there's no solid record she ever had malaria at all. The genus name even misspells her title, dropping an 'h' (Chinchón became Cinchona), a slip Linnaeus never fixed. True or not, the story and the bark together carried quinine out of the Andes and into the world's medicine chests.
