grapefruit Fruit of Citrus paradisi; thought to have arisen as a sport of the pomelo or shaddock (Citrus grandis), a coarser citrus fruit, or as a hybrid between pomelo and sweet orange. It contains 35–40 mg vitamin C per 100 g. The pith contains naringin, which is very bitter. Named by the botanist John Lunan in Hortus Jamaicanensis (1814) because the fruits grow in “grape‐like” clusters. The ruby grapefruit, with red flesh, was discovered as a sport in Texas in 1929.
