Ltppla (Lemon-Scented Verbena). The common species cultivated 

 in greenhouses, from Chili, is better known under the name of Aloysia 

 citriodora, but some of our botanists consider Lippia as the proper name 

 of the genus. There are several other species, but they are rarely 

 cultivated. 



Liquidambar (Sweet Gum Tree). A genus of one North American 

 and one oriental species. The first is a widely-distributed, handsome 

 forest tree of large size, with bright green, star-shaped leaves which usu- 

 ally change to a dark red or crimson color in autumn. Propagated by 

 seed sown as soon as ripe in the fall, in very moist soil. Some of the seed 

 may germinate the following spring, but they usually remain dormant 

 until the second season, and for this reason it is well to sow them where 

 the bed can be watered during dry weather in summer. 



Liriodendron (Tulip Tree, White Wood). A very large and 

 widely-distributed indigenous forest tree, valuable for its timber, and 

 highly prized as an ornamental tree. Only one species, the L. Tulipifcra. 

 Propagated by seeds sown as soon as ripe in the autumn, and 

 covered about a half-inch in depth with leaf-mold or other light 

 soil. The seedlings are inclined to make very long, slender tap-roots, 

 and they should be frequently transplanted while young, if they are to 

 be moved when large or several feet in height. The transplanting 

 should always be done in the spring, for the Tulip tree and other mem- 

 bers of the Magnolia Family have rather soft, spongy roots, liable to 

 injury from cold and moisture, if disturbed in the fall, and, while seed- 

 lings and larger trees may be taken up and hecled-in and given protection 

 during the winter months, it is seldom safe to plant them out in nursery 

 rows or elsewhere in the fall at least not in cold countries. 



Lonicera (Honeysuckle.) A very extensive genus of ornamental, 

 upright and climbing shrubs. In some botanical works, the species of 

 this genus are separated into two groups, the upright-growing under the 

 above name, and the climbing under that of Caprifolium. All, how- 

 ever, belong to the Caprifoliaccce, or Honeysuckle Family. All readily 

 propagated by layers put down in fall, or early spring, also by ripe wood 

 cuttings in the open ground, and green cuttings under glass. 



Lyctum (Matrimony Vine). Numerous species ; mostly hardy, but 

 a few from the Cape of Good Hope are tender and cultivated in green- 

 houses. The best known is the common Matrimony Vine (L. vulgarc), 

 from Southern Europe, a slightly thorny, half-climbing shrub, with small, 

 greenish-purple flowers, succeeded by red berries. Easily propagated 

 by cuttings of the mature one-year-old wood, or by seed. 



Lyonia. See Andromeda, Cassandra, Oxydcndrum. 



Madura (Osage Orange, Bow-Wood). A well-known native tree 

 of our Southwestern States. Formerly extensively planted for farm 

 hedges, the young branches being well famished with strong, sharp 

 epiues. The best mode of propagation is by seed sown in spring, in
