THE NURSERY LIST. 145 



Buxus (Box Tree). Euphorbiacece. 



Propagated by seeds sown as soon as ripe, in any light, 

 well-drained soil. They can be increased by suckers and 

 divisions ; by layers of young or old wood, made in autumn 

 or early spring ; by cuttings made of the young shoots, from 

 four to six inches in length, in a sandy place in spring or 

 fall. The latter method is the better way in this country, and 

 in the north the cuttings should be handled under glass. 



Byrsonima. Malpighiacece. 



Increased by cuttings of half-ripened shoots in sand under 

 a hand-glass, in moist bottom heat. 



Cabbage {Brassica oleracea, and vars.). Cruciferce. 



Seeds. They may be sown in the open ground in spring, 

 or in the fall and the young plants wintered in a cold-frame, 

 or in a hot-bed or forcing house in late winter and spring. 

 Brussels sprouts, broccoli and cauliflower are treated in the 

 same manner. 



Cabbage Palm. See Areca. 



Cabomba. Nymphceacece. 



Propagated by root divisions. 



Cacalia. See Senecio. 



Cacao. See Theobroma. 



Cactus. Cactece. 



Propagation by seeds is not often adopted, as it is a very 

 slow method. The seeds should be sown in very sandy soil, 

 and placed in a semi-shady position until germination com- 

 mences, when they may be exposed and very carefully 

 watered. Usually propagated by cuttings or offsets, which 

 should be made with a sharp cut, and laid upon a sunny 

 shelf or on dry sand until the wound is healed and roots em- 

 itted, when they should be potted in sandy soil. Place with 

 the others, and keep syringed. Grafting is resorted to with 

 weak kinds, which will not grow freely except upon the stock 

 of a stronger species ; and by this means, also, such kinds 

 can be kept from the damp soil, .which frequently causes de- 

 cay. The stocks usually employed are those of Cereus tor- 

 tuosus, C. peru-vianus, Pereskia aculeata, etc., according to the 

 species intended for working ; they readily unite with each 

 other. If the scion and stock are both slender, cleft-graft- 

 ing should be adopted ; if both are broad it is best to make 

 horizontal sections, placing them together and securing in 

 proper position by tying with matting, but not too tightly, or 

 the surface may be injured.
