Citron
The citron ("Citrus medica") is a large fragrant citrus fruit with a thick rind. It is one of the original citrus fruits from which all other citrus types developed through natural hybrid speciation or artificial hybridization. Though citron cultivars take on a wide variety of physical forms, they are all closely related genetically. It is used widely in Asian cuisine, and also in traditional medicines, perfume, and for religious rituals and offerings. Hybrids of citrons with other citrus are commercially prominent, notably lemons and many limes.
Siracusa Lemon
The Siracusa lemon (in Italian, "Limone di Siracusa IGP") is the fruit of the cultivar "femminello siracusa" and its clones, corresponding to the botanical species Citrus x limon L. Burm. The "femminello siracusano" cultivar is the most common variety of lemon in Italy, with the Province of Syracuse (Siracusa) region accounting for 42% of the national lemon-growing land area.
