[Fr. and Ital., from Pers. naranj, with n dropped.] An evergreen tropical and semi-tropical tree, seldom rising above 25 feet in height. The fruit is usually round, and consists commonly of ten pulpy parts enclosed in a leathery rind. The flowers, which are of a delicate white color, appear in summer, but the fruit is not ready for picking till the following year. Hence flowers and fruit in various stages may be seen on the trees at the same time. There are numerous varieties of the orange, which is cultivated in all the warmer regions of the earth. In the United States it is raised largely in Florida and California. The blood orange has a reddish juice. The mandarin orange is small, is thought to be of Chinese origin, and is counted a distinct species. The Seville or bitter orange is grown in large quantities in Spain, and imported into Great Britain and the United States for making marmalade. The rind is made into candied orange-peel. The leaf, the flower, and the rind of the fruit all yield volatile oils. The scent of eau de Cologne is due chiefly to oil distilled from the orange flower, while the rind of the bergamot orange yields essence of bergamot, largely used in perfumery.
