Grapefruit (Citrus paradisi).—Grant Heilman Photography

Tree (Citrus paradisi) of the rue family and its edible fruit. It originated in the West Indies (probably Jamaica) before being brought to the New World mainland. The shiny, dark green foliage is very dense. The large white flowers are borne singly or in clusters. Lemon-yellow when ripe, the fruit is 4–6 in. (100–150 mm) in diameter, about twice as large as a medium-size orange. The mildly acidic pulp—juicy and light yellowish, pink, or red—is an excellent source of vitamin C. It is popular as breakfast fruit in various parts of the world.
