THE NURSERY-BOOK. 



Nauclea. Rubiacea. 



May be increased by cuttings of growing shoots, in heat. 



Nectarine. See Peach. 



Negundo (Box Elder). Sapindacece. 



Propagates with readiness by seeds, which should be sown 



as soon as ripe. Also by cuttings of mature wood, handled 



like grape cuttings. 



Neillia. Handled the same as Spiraea, which see. 



Nelumbo, Nelumbium (Water Chinquapin, Lotus, Water 



Bean). Nymphceacece. 



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 very carefully filed or bored (see Fig. 7). Sections 

 of the rhizomes may be used instead. They should always 

 be covered with water, at least a foot or two deep, if out- 

 doors. 



Pfemastylis, Nemostylis. Iridece. 



Propagation is effected by seeds, or by bulbels. 

 Nematanthus. Gesneracece. 



Seeds rarely. Freely increased by cuttings, inserted in 

 sandy soil and kept rather dry. 



Nemopanthes (Mountain Holly). Ilidnecc. 



Increased by seeds, which should be sown as soon as ripe 

 or else stratified ; also by division of old plants. 



Nemophila. Hydrophyllacece. 



Seeds may be sown in late summer or any time during 

 early spring. 



Nepenthes (Pitcher Plant). Nepenthacece. 



Propagated by seeds and cuttings. The seeds must have 

 good drainage, uniform conditions and strong heat (80 

 to 85). Sow upon a soil made of peat and fine sphagnum, 

 and keep in a moist and close frame. Cuttings are usually 

 struck in moss in a frame having strong bottom heat. A 

 good plan is to fill a small pot with moss, invert it, and insert 

 the cutting through the hole in the bottom. The pot then 

 keeps the moss uniform. The pot is broken when the plant 

 is removed. When potting off, use very coarse material.
