ABSTRACT

The citron is a large, thorny, subtropical shrub or small tree, 2.4 to 4.5 m (8-15 ft.) tall. Citron fruits are elongated, with a lumpy, warty, or knobby (occasionally smooth) surface, attractive fragrance, thick greenish-yellow peel, acidic §esh divided into segments, and many seeds in the pulp. The citron is closely related to the lemon, but the fruit can be much larger-up to 9 kg (20 lb.). The peel or rind makes up most of the fruit. Two main classes of citrons are the sweet or Corsican and the acid citrons. Both have fruit that is large and elliptical in shape, with a diameter of 7.5 to 12.5 cm (3-5 in.), length of 10 to 18 cm (4-7 in.), and rind about 2.5 cm (1 in.) thick.
