hardy species in autumn. Ripened cuttings will root freely 

 in a compost of loam, peat and sand. 



Celery. (Apium graveolens]. Umbelliferce. 



By seeds, as described on page 12 ; or, for the early crop, 

 sow under glass, as in a hot-bed. 



Celosia (Cockscomb). Amaranlacece. 



Propagated by seed sown in spring, in pans of well-drained, 

 rich, sandy soil or in the open. 



Celsia. Scrophularinece. 



Increased by seeds, which may be sown in the open bor- 

 der and thinned out for flowering, or raised in nursery beds 

 and transplanted. C. Arcturus should be increased by cut- 

 tings, the young wood striking freely in a cool house or 

 frame. 

 Celtis (Nettle-tree). Urticacece. 



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

 By layers, and by cuttings of ripened shoots in autumn. 



Centaurea. Composite. 



Annuals by seeds, which may be sown in the open border. 

 To propagate C. Cineraria, and some others sow seeds in 

 August in slight heat, or make cuttings about the beginning 

 of September. 

 Centranthus. Valerianece. 



Increased by seeds sown in spring. 

 Centronia. Melastomacece. 



Propagated by cuttings of half-ripened shoots, which 

 should be inserted in peat and sand, under glass. 



Centropogon. Campanulacece. 



Increased by seeds, by divisions and by cuttings from any 

 young shoots three or four inches long. Take off with a 

 heel and place in sharp sandy soil, close around the edge of 

 the pot, and then keep close under a propagating box, in a 

 temperature ranging between 60 and 70. 



Cephaelis. Rubiacce. 



Increased by cuttings of firm young shoots, which will root 

 well in sandy soil under a hand-glass, in moist stove heat. 



Cephalanthus (Button-wood). Rubiacca?. 



Seeds. Propagated by layers or ripened cuttings in au-
