This species (Citrus decumana) is quite closely allied to the orange, and it is the most ornamental tree of the genus when laden with its large golden fruit. Its flowers are large, white, and very fragrant. Its fruit runs into a great number of varieties of all shapes, such as oblate, oval, pyriform, and flattened, and the quality varies quite as much. In Cuba we found the fruit quite as popular as the orange, and even more so with the well-to-do classes, as it has an acid mingled with a slight bitter taste that is peculiarly refreshing in hot climates. It is prepared by taking out the bitter membranes and sprinkling the tender pulp with sugar. What is known as the pomelo commercially are round, often six to seven inches in diameter, weigh from eight to ten pounds, and the fruits grow singly. The type called grape-fruit is not larger than an overgrown orange and it grows in clusters. This is shipped North more generally than the large pomelos.

The commercial varieties are usually propagated by budding on the rough-lemon stocks and on the sour orange. The trees are not as hardy as the orange, but in nearly frostless regions it is a clean, healthy tree, not liable to disease or troubled with scale or other insects. In south Florida the culture of the best varieties is being rapidly extended, and the same is true in Cuba and Porto Rico.
