Chináchón /chin-'chOn,/ Countess of (Doña Francisca Henriquez de Ribera), vicereine. According to a legend firstgiven out in 1663 and supposedly based on a now-lost letter, Countess Chinchón, the wife of the viceroy of Peru, fell ill with malaria. The governor of a neighboring province quickly provided aremedy in the form of a certain tree bark. The countess experienced a seemingly miraculous recovery, and word of the bark's extraordinary powers quickly spread. The name of the countess henceforthbecame associated with the bark. While the story is apocryphal, Linnaeus perpetuated the name of the countess, albeit in misspelled form, by designating the genus of that tree Cinchona in herhonor.
