Small, spreading trees or shrubs: young branches smooth, yellowish green:
Cultivated extensively in all tropical and subtropical regions of the world.-The Lemon is one of our most important commercial fruits, and is grown extensively
in California and Florida. Large quantities of the fruit are also imported. mainly from Italy.
The Lemon is not so easily injured by cold as the citron, but is more tender than the orange or pomelo. The entire fruit, rind and pulp. is used extensively for culinary and con fectionary purposes, for the manufacture of citric acid
and for lemonade, etc. It is commonly prop. by seeds, but may also be readily grown from cuttings. he cul tivated varieties must be prop. by budding or grafting, or by cuttings, as they do not come true to seed.
The following are the most important horticultural varie ties : Belair: Fr. lemon-shaped, blunt. Foreign.—Eu reka: Fr. early, few-seeded: tree tlsornless. Foreign. Genoa: Fr. medium size, early, oval, nearly seedless: tree everbearing.thornless. Foreign.—Lisbon : Fr. me dium size, fine grained, strongly acid; few seeds: tree thorny. Foreign.—Villa Franca: Fr. medium size, quality excellent; rind smooth, thin; seeds few or none. One of the linest Lemons grown. —The so-called Fingered Citron or Lemon, var. digitata, Risso (or var. chiroczrpa), in which the individual carpels of the fruit are separated above, is an interesting and striking monstrosity.
The Florida Rough Lemon, or simply "rough lemon" as it is called, is a fruit of doubtful relationship. Its appearance suggests that it may be a hybrid between the Citron and Lemon. It is a strong, vigorous grower, and forms an excellent stock, in warm localities, for the various orange varieties. It is the best stock for the Bahia navel orange, usually increasing its fruitfulness.
Var. acids, Hook. (0. Médica, var. Liméfla of trade catalogues, etc.). LIME. A bush or small tree, 10-20 ft. high : lvs. oval or elliptical, small, crcnnte or serrate; petiole wing~margined, but not as broadly so as in the sour orange and pomelo: fls. small, white or with aslight pinkish tinge without; petals normally 5, but often 4 : fr. small, spherical, ovate or elliptical ; rindthin, light lemon-yellow, bitter; pulp very sour and somewhat bitter, juicy. India.
Extensively cultivated in the West Indies and Florida, where it as escaped from cultivation and grows abundantly wild, frequently forming dense thickets. B. liI.67~i5. The horticultural varieties commonly cultivated in the United States are : Mexican (West Indian): Fr. small, oblong. Escaped from cultivation in South Florida and the West Indies. Supposed to have been introduced from Mex. Persian: Fr. larger than in the preceding; said to be of excellent quality. Introduced from Persia.—Rangpur (Mandarin Lime): Fr. resembling a mandarin orange in having easily removable rind and separable segments or ca els; said to be of excellent quality. Introduced from India.—Tahiti: Fr. large, early, nearly seedless, of line qualirtlyz tree nearly thornless; prolific. Intro duced from ahiti. This is probably the most highly prized variety of Lime grown. Until recently, the Lime had been used mainly for the manufacture of lime juice, which had become a standard article of commerce, and citric acid. Recently, limeade has became very popular at the soda fountains throughout the country, and this use is so rapidly extending that in a few years it will doubtless make Lime-growing an important industry.
