possible to secure the necessary heat, cuttings of the hard 

 wood can be used in autumn, under glass. 



Liquidambar (Sweet Gum). Hammelidece. 



Seeds, which should be stratified or sown as soon as ripe. 

 Many of the seeds may lie dormant until the second year. 



Liquorice. See Glycyrrhiza. 



Liriodendron (Tulip-tree, Whitewood). Magnoliacece. 



Increased by stratified seeds. Named varieties are grafted 

 on seedlings. The seeds of the tulip-tree are apt to be hol- 

 low, especially those grown along the eastern limits of the 

 distribution of the species. 



Lisianthus. Gentianecc. 



The annuals may be increased by seeds, those of a shrubby 

 habit by cuttings. 



Litchi. See Nephelium . 



Lithospermum, including Batschia (Gromwell). Boraginece. 

 May be propagated by seeds, by divisions, or by cuttings. 



Livistona, Latania, Saribus (Fan Palm). Palmce. 



Seeds, sown in a sandy soil and placed in a gentle bottom 

 heat. 



Lloydia. Liliacece. 



Seeds rarely. Increased by bulbels, or by the creeping 

 shoots leaving a bulb at the extremity. 



Loasa, including Illairea. Loasece. 



All are easily increased by seeds sown in a light, sandy 

 soil, usually under cover. Cuttings are rarely used. 



Lobelia. Campanulacece. 



Ordinarily increased by seeds, which are more certain if 

 handled in pans or flats under glass. Cuttings from vigor- 

 ous shoots may be employed, and strong plants of some 

 species may be divided. The cardinal flower (L. cardinahs] 

 is grown from seeds carefully sown in fine soil, usually 

 under cover. 



Locust-tree. See Robinia. 

 Loddigesia. Leguminosce. 



Increased in spring by cuttings placed under glass, in 

 sandy soil.
