heat; when rooted, the plants should have night temperature of 

 about 60, being hardened off if to be placed out-of-doors. 



Lucuma. Sapotacece. 



The genus comprises several species of tropical fruits, usually 

 propagated by seeds, the outer husk being first removed and the 

 seed planted at once in sandy soil. Of the mamey sapote (L. 

 mammosa), seedlings may be expected to bear at five to seven 

 years of age. Seedlings of the ti-es (L. nervosa) should bear in 

 three to seven years. 



Luffa (Dish-cloth Gourd. Vegetable Sponge). Cucurbitacece. 



Propagated by seed, sown in the open, or in the North better 

 started in pots in early spring. The species are frost-tender and 

 in general should be handled as cucumbers and melons. 



Lunaria (Honesty). Cruciferae. 



The biennial species is propagated by seeds and the perennial 

 also by division. 



Lupinus (Lupine). Leguminosae. 



Seeds may be used for the easy propagation of all the species, 

 usually being sown where the plants are to grow, as they do not 

 bear transplanting well after attaining some age. The perennial 

 species forming stools may be increased by division. 



Ly caste. Orchidacece. 



Propagation by division and pseudobulbs. See Orchids, page 372. 

 Lychnis, including Agrostemma and Viscaria. Caryophyllaceoe. 



Propagated readily in spring by seeds, the perennials also by 

 division and sometimes by cuttings. 



Lycium (Matrimony- Vine. Box-Thorn). Solanaceas. 



Propagated by seeds and layers ; and also by hardwood cuttings 

 in autumn or spring, and some species by the natural suckers. 



Lycopersicum : Tomato. 



Lycopodium (Club-Moss). Lycopodiaceos. 



Increased by spores, as for ferns (which see) and by short cuttings 

 in pans or pots ; sometimes by layers. See Selaginella. 



Lycoris. Amaryllidaceoe. 



Propagated by offsets, as for amaryllis ; also by seed if pro- 

 curable, but longer time is usually required.
