CRITHMUM CUCUMBER. 2IQ 



a temperature of from 70 to 80, and keep rather dry 

 until the plants appear, when more moisture should be 

 applied. Also increased by offsets, which should be re- 

 moved when rather small and potted separately, and 

 grown as recommended for seedlings. 



Crithmum. Umbelliferez. 



Propagated by seeds sown as soon as ripe, and by 

 divisions. 



Crocosmia. Iridaceez. 



Propagated by seeds sown in pans in a cold house as 

 soon as possible after maturity. Also by offsets. 



Crocus. Iridacecz. 



Propagated by seed, sown as soon as ripe or early in 

 spring, the choicer strains in pots or boxes, using a light, 

 sandy soil, and afterwards placing them in a cold pit or 

 frame ; the more common varieties may be placed in a 

 warm position outside in a seed-bed. Sow thinly, so that 

 the plants may grow two years in the seed-pan or bed 

 without lifting. By the cprms. These may be lifted and 

 replanted, allowing each in its turn to develop new corms 

 below. The following year new corms, or cormels, are 

 also formed by the side of the old corms. These old 

 corms die away annually. Some species increase much 

 more rapidly than others. (See page 31.) 



Crotalaria (Rattle-box). Leguminosce. 



Increased by seeds. The shrubby kinds by young cut- 

 tings, which root freely in sand, under glass, in a cool 

 house. 



Croton. See Codiaeum. 

 Crowfoot. See Ranunculus. 



Crucianella (Crosswort). Rubiace<z. 



Propagated by seeds, by divisions during spring or 

 autumn, and by cuttings. 



Cryptomeria (Japan Cedar). Conifertz. 



Increased by seeds, and by cuttings of growing wood 

 planted in sandy soil, under glass. 

 Cubeba. See Piper. 

 Cucumber (Cucumis sativus}. Cucurbitacece. 



Seeds. If sown outdoors, the operation should be 

 delayed until the weather is thoroughly settled.
