This is a smaller tree than the preceding; the leaves are more elliptical; the flowers are more decidedly white, and yield a stronger perfume; the rind of the fruit is not yellow, but deep orange color, and the pulp is acid and bitter. A good distinctive character is found also in the re markable unevenness of the fruit.
The rind of the fruit, which is bitter, contains a volatile oil, and is employed as a constituent of the compound infusion, the mixture, and the compound tincture of gentian. This and other parts of the plant are used for the same purposes as the sweet orange.
