Sour varieties include the Florentine and diamante citrons - from Italy - and the Greek Balady citron from Israel.
Sweet varieties include Corsican and Moroccan citrons.
The pulpless varieties are the fingered types and the Yemeni citron.
There are many citron hybrids, such as ponderosa lemon or lumia. Some say that even the Florentine citron is not a pure citron but a citron hybrid.
