OF ORNAMENTAL EXOTIC PLANTS. 49 
1.—CITRUS MEDICA Risso. THE CITRON. 
Encravines.—Black. Herb., t. 361; Nouveau Duhamel, vol. vii., | oblong, obtuse, flowers with from thirty-five to forty stamens, often 
t, 22. without a style ; fruit oblong, wrinkled, with a thick rind and acid 
Speciric Cuaracter,—Branches spiny; petioles naked; leaves | pulp. (G. Don.) 
Description, &c.—The stem of this species rises to the height of twelve or fifteen feet, and the branches, 
instead of taking the close compact character usually found in orange-trees, spread widely, and assume a tree-like 
character. The flowers are purplish on the outside, and less odoriferous than those of most other species of the 
genus. The pulp is white and acid, and the rind is very thick and irregular. There are generally two seeds 
in each carpel. The fruit of the Citron is scarcely ever eaten raw, but when preserved, it makes a delicious 
sweetmeat. The species is a native of the warm regions of Asia, whence it was introduced in 1648. There are 
many varieties on the Continent, but seldom more than three are grown in this country. 
2.—CITRUS LIMETTA Risso. THE SWEET LIME. 
Synonyme.—Lima dulcis Volk. serrulated. Flowers very white. Fruit globose, crowned, terminating 
Eneravinc.—Nouveau Duhamel, vol. vii., t. 26, fig. 2. in a point; rind very thin; flesh sweet. 
Sprreciric Cuaracter—Petioles subulate. Leaves ovate, roundish, 
Derscription, &c.—This species forms a handsome tree, with compact branches, which are easily trained into 
a round head. The young shoots are of a yellowish green, while those of the Citron are purplish; and the flowers, 
which are of a beautiful white on both sides, are very fragrant. The petioles of the leaves have scarcely any wings. 
The flowers are disposed alternately all along the branches, and each has about thirty stamens, the filaments of 
which are flattened, and adhere at their base into little bundles of three each. ‘The fruit is rather small and 
round, terminating in an obtuse protuberance like that of the Lemon. ‘The rind is very thin, of a dark orange- 
yellow, and it adheres firmly to the pulp, which is divided into from seven to ten cells. The juice is sweet, and 
has a delightful perfume. The seeds are very few in number, and are of an oval shape. ‘There are ten varieties ; 
the most ornamental of which is called the Bergamot, from its delightful perfume, and from the pulp of which, 
though it is bitter to eat uncooked, various kinds of sweetmeats are made. ‘There is another kind of Lime, the 
fruit of which has an acid juice, and a much paler rind. The species was introduced in 1648. 
3.—CITRUS LIMONIUM Risso. THE LEMON. 
Synonymes.—C. Limon Zim.; Limon acris Ferr.; Limon vulgaris | oblong, crenulated; flowers with from twenty-five to thirty-five sta- 
Black. mens, but usually without styles; fruit oblong, with a very thin rind, 
Enerayvinc.—Nouyeau Duhamel, vol. vii., t. 28. and very acid pulp. (G. Don.) 
Sreciric Cuaracter.—Petioles somewhat winged; leaves ovyal- 
Description, &c.—The Lemon makes a very handsome tree, though its branches are somewhat angular. The 
young shoots are purplish, and the flowers haye the same hue on the outside of the petals. The Lemon tree is 
remarkable for its fecundity, as it continues to flower and produce fruit from February to October, and sometimes 
the flowers continue expanding all the winter. The flowers are very fragrant when they first open, but their 
fragrance soon goes off. The fruit is oblong, terminating in a protuberance ; the rind is of a pale yellow, thin but 
compact, frequently rough on the outside, but closely adhering to the pulp within. The pulp is divided into ten 
cells, which contain a very acid juice. There are. many varieties of Lemons, but the most curious is the Chinese
