The citron is a fragrant citrus fruit, botanically classified as "Citrus medica" by both, the Swingle and Tanaka systems. The designation medica is apparently derived from its ancient name "Median apple" that was influenced by Theophrastus who believed it to be native to Medes. The citron has many similar names in diverse languages, e.g. cederat, cedro, etc. Most confusing are the Polish, Czech, Slovak, French, Dutch, German, Yiddish and Scandinavian languages, in which the false friend "citron" refers to the fruit called lemon in English. The French name for citron is "cedrat".
