Pummelo citrus maxima (Burm.) Merr. (Rutaceae) The pummelo is native to Indonesia, Malaysia and New Guinea where it has been known for over four thousand years. It is an ancestral species from which, through a series of crosses, different citrus' species are now widely used by man, for its food. Its particular fruit, spheroidal in shape, generally reaches a diameter of up to 30 cm and a weight of approximately 2,5 kg. The film that wraps the wedges, thick and leathery, is not edible, while the juicy pulp is very popular in desserts in some Far Eastern countries. The fruits are also used for the production of jams and the peel, which reaches 2 cm in thickness, for the production of candied fruit. www.ortobotanico.unipa.it
