CIMICIFUGA CISTUS. 211 



Cimicifuga (Bug wort). Ranunculacecz. 



Increased by seeds, sown in a coldframe or border as 

 soon as ripe ; or by division of the roots in spring. 



Cinchona (Peruvian Bark). Rubiace ce -. 



Imported seeds, and cuttings taken off when ripe and 

 planted in a pot of sand, under glass, in a moist heat. 



Cineraria. Composites. 



Seeds should be sown under glass ; those intended for 

 autumn flowering in April and May, those for spring in 

 July and August. Light leaf-mold should be used, and 

 about an equal quantity of fresh sifted loam and sharp 

 sand added, the whole being well mixed. Old cow-ma- 

 nure is a good medium in which to sow (see page 20). 

 Also by divisions and by cuttings. 



Cinquefoil. See Potentilla. 



Cipura. Iridacecz. 



Propagated by seeds, which should be sown in a slight 

 heat in spring ; or by bulbels, which are abundantly 

 produced. 



Cissampelos. Menispermacecz. 



Propagated by cuttings, which root readily in heat. 



Cissus. Vitacecc. 



Propagated by cuttings in the spring. Choose the 

 weakly shoots that are pruned just before the plants 

 break into new growth, or allow the young shoots to 

 grow to a length of about two inches. Then cut them 

 off, with a small piece of the basal branch adhering to the 

 young wood ; or the shoots may be cut off with one or 

 several of these young branchlets on them. Cut the old 

 branch through at the base of each young one, and in- 

 sert the cutting with this heel of the old wood entire. 

 In this country, usually grown from common green cut- 

 tings in summer. 



Cistus (Rock Rose). Cistacece. 



Propagated by seeds, by layers or cuttings under frames 

 outside, or inside with a gentle bottom heat ; but seed- 

 lings always make the best plants. The seeds should 

 be sown early in the spring in pans or boxes in a frame, 

 and lightly covered with sifted sandy mold. Cuttings
