THE NURSERY-LIST 295 



off when the cuttings are removed from the cutting-bed, either to 

 be sold or to be transplanted into nursery rows. Strong plants, 

 such as eastern markets demand, are usually obtained by allowing 

 the cuttings to stand for two years before sale. Fig. 111. 



Green layering is sometimes practiced with rare sorts, or single 

 eyes may be used, as in grapes. Tip-layering, as in the black rasp- 

 berry, may also be employed. 



Weak or low sorts are sometimes grafted on stronger ones, in 

 order to give them a tree form, but such bushes are grown only as 

 curiosities or as specimen plants. 



Cyanophyllum : Miconia. 



Cyathea. Cyatheacece. 



Propagated by spores. See Ferns, page 312. 



Cycas. Cycadaceae. 



Propagated by seed, and oftener by suckers. The seeds will 

 keep for a month or more after they get ripe. They are best sown 

 in shallow boxes or benches, covered in sand, and potted soon after 

 germination. 



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. Primidacece. 



Propagated by fresh seed, usually sown by florists in early 

 winter. The plants should be shifted as needed and kept growing. 

 Bloom may be expected in about fifteen months. Old tubers may 

 be used for second blooming, but seeds give best results. 



The hardy cyclamens, which are little known in this country, are 

 grown from seed handled in frames or seed-beds in the open ; also 

 by division. 



Cydonia : Quince, Chcenomeles. 



The Japan quince is now named in the genus Chsenomeles. 



Cymbidium. Orchidacece. 



Multiplied by division of the roots. See Orchids, page 372.
