CUSSONIA CYPERUS. 221 



but such bushes are grown only as curiosities or as 

 specimen plants. 



Cussonia. Araliacece. 



Increased by cuttings, which should be planted in sand, 

 under glass. Give slight bottom heat. 



Custard Apple. See Anona. 



Cyananthus. Campanulacea '. 



Seeds. Strong roots may be carefully divided in 

 spring, but this is not desirable. Usually by cuttings, 

 which should be taken during spring or early summer, 

 and struck in sandy peat, being kept moist. 



Cyanophyllum. Melastomacefz. 



Increased by seed. By cuttings or eyes, which should 

 be placed in sand, where a good bottom heat must be 

 maintained, and they should be shaded from the sun. 



Cyathea. See Ferns. 



Cycas. Cycadacecz . 



Increased by seed, and oftener by suckers. Some, and 

 perhaps all, of the cycads can be propagated by sections 

 of the old stem or trunk. Cut the trunk into truncheons 

 2 or 3 inches thick, usually slanting ; let the pieces dry a 

 few days to guard against rotting, then plant in pots or 

 sand. Roots will form between the scales, and new 

 plants will push out. These should be removed and 

 treated as independent plants. The severed crown of 

 the trunk may also be potted, and it will grow. 



Cyclamen (Sowbread ) . Primulacecz. 



Propagated by seed, sown when freshly gathered ; the 

 hardy kinds in pots placed in a cool frame. By divisions, 

 and leaf cuttings taken off with a heel ; but these meth- 

 ods are not very satisfactory. 



Cypella. Iridacetz. 



Propagated by seed, sown as soon as ripe in a cool 

 house, and by offsets. 



Cyperus. Cyperacecs. 



Propagated either by seed, sown in gentle heat, or by 

 divisions. C. alternlfolius, the umbrella-plant, propa- 

 gates readily from the crown or rosette of leaves. Cut 

 pff the crown, with an inch or two of stem remaining,
