creased 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. Capparidece. 



Increased by seeds sown in a frame in spring, with slight 

 warmth. Ripened cuttings root freely in moderate heat. 



Clerodendron, Ovieda, Siphonantha, Volkameria. Verbenacece. 

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

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

 ing 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 cut- 

 tings as the others, but cuttings of the ripened wood do well. 



Clethra. Ericaceae. 



Propagated by seeds, divisions and layers. Cuttings taken 

 from the half-ripened wood will root in gentle heat. 



Clianthus (Glory Pea, Parrot Beak). Leguminosce. 



C. Dampieri is best raised from seeds, which should be 

 sown singly in good-sized pots, when the necessity of first 

 shifting will be obviated. C. puniceus and others from cut- 

 tings, which strike easily in sand in bottom heat. 



Clintonia. Liliacece. 



Propagated by seeds and by division of the root in spring. 

 Clitoria Leguminosce. 



The best method of increasing is by seeds. Increased also 

 by cuttings of stubby side shoots, which will root in sandy 

 soil, in heat. 



Cliva, Imantophyllum. Amaryllidece. 



Propagated by seeds or divisions. 

 Clove-tree. See Caryophyllus. 

 Clusia (Balsam-tree). Gutliferce. 



Increased by cuttings of half-ripened shoots, which will 

 strike in sand, with bottom heat. 



Cobsea. Palemoniacece. 



Readily raised from fresh seed in spring, if a gentle bot- 

 tom heat is supplied. It is often said that the seeds must 

 be placed on edge, but this is a mistake. From cuttings taken
