will also root readily. The treatment for achimines applies in 

 general. See Gesneriacece, page 318. 



Nandina. Berberidaceoe. 

 Increased by seeds. 



Narcissus (Daffodil. Jonquil. Chinese Sacred Lily). Amaryl- 



lidaceas. 



New varieties are grown from seeds, which give flowering bulbs 

 in three or four years. Ordinarily increased by bulbels or offsets 

 from the bulbs, which usually flower the second year. 



Nectarine : Peach. 



Negundo (Box Elder). Aceracece. 



Grows readily from seeds ; also by cuttings of mature shoots, as 

 for grapes. See Acer. 



Nelumbo, Nelumbium (Water Chinkapin. Lotus. Water Bean). 



Nymphaeacece. 



Propagation by seeds, which may be sown in shallow pans of 

 water in the garden, or if sown in ponds they may be incorporated 

 in a ball of clay and dropped into the water. The seeds of some 

 species are very hard, and germination is facilitated if they are 

 carefully filed or bored. Sections of the rhizomes may be used 

 instead ; they should always be covered with water, at least a foot 

 or two deep, if outdoors. The false lotus or sacred bean (N. nu- 

 cifera) may be increased by division and seeds. The roots or tubers 

 should not be transplanted until they show signs of young growth. 

 If they are disturbed before growth commences, the tubers should 

 be kept in a warm place where growth will begin at once. 



Nemastylis. Iridacece. 



Propagated by seeds and by bulbels. 



Nemesia. Scrophulariaceae. 



Flower-garden plants growing readily from seeds, which may be 

 started indoors or sown directly in the open. 



Nemopanthus (Mountain Holly). Aquifoliacece. 



Handled by seeds, which should be sown as soon as ripe or else 

 stratified ; also by division of old plants and by greenwood cuttings 

 under glass.
