should be made from 3 to 4 inches long. They may be 

 struck in spring or autumn, in sandy peat, under glass. 



Citron ( Citrus Medica ) . Rutacecz. 



Seeds, which usually reproduce the kind. Mature cut- 

 tings, the same as lemon. Also budded on orange, 

 lemon or lime stocks. 



Citrus. Rutacetz. 



Increased by seeds, layers, cuttings, inarching, grafting 

 and budding. For particular methods, see ^Egle, Citron, 

 Kumquat, Lemon, Lime, Orange and Pomelo. 



Cladrastis (Yellowwood). Leguminoscz. 



Propagated by seeds sown in the open air in spring, or 

 by cuttings of the root. 



Clarkia. Onagracece. 



Increased by seeds, which may be sown in spring or 

 autumn outdoors. 



Clematis (Virgin's Bower). Ranunculacecz. 



Clematis may be increased by seeds. The seed-heads 

 should be gathered before autumn, and stratified till the 

 following spring, when the seeds may be sown in light, 

 sandy soil, and placed in gentle heat till they germinate. 

 By layers outside, put in at any time. All the varieties 

 of clematis may also be increased by cuttings made of 

 the young shoots, which may be cut up to every eye and 

 planted in gentle heat. Also by grafting any of the 

 varieties on portions of clematis roots in winter. Good, 

 healthy pieces of root obtained from old plants answer 

 the purpose well. See also Atragene. 



Cleome. Capparidacece. 



Increased by seeds sown in a frame in spring, with 

 slight warmth. Ripened cuttings root freely in moderate 

 heat. 



Clerodendron, Volkameria. Verbenacece. 



Increased by seed, which, if sown when ripe or in the 

 spring, and grown on in heat, may be converted into 

 flowering plants the second season. Propagated also by 

 cuttings of both green and mature wood ; also of roots. 

 Suckers. The climbing varieties do not root quite so 

 readily from cuttings as the others, but cuttings of the 

 ripened wood do well.
