THE NURSERY LIST. 169 



Cotyledon (Navel wort). Crassulacece. 



Increased by seed, offsets, cuttings of the stem, and by 

 leaves. The leaves should be pulled off in autumn, laid on 

 dry sand in pans on a shelf in a propagating or other warm 

 house, and not watered until small plants appear at the ends 

 of the leaves. 



Cowslip. See Primula. 

 Crambe. Crudferce. 



Increased by seeds, by dividing the roots and by root cut- 

 tings. See Sea-kale. 



Cranberry (Vacdnium macrocarpon). Ericaceae. 



The cultivated cranberry is propagated entirely by cut- 

 tings. These are made from vigorous young runners, from 

 six to ten inches in length, and they are thrust obliquely into 

 the soil until only an inch or two of the tip projects. Some 

 blunt instrument, as a stick, is commonly used to force them 

 into the sand of cranberry bogs. Planting is done in the 

 spring, and the cuttings are taken just previous to the oper- 

 tion. If cranberry seedlings are desired, the seeds should be 

 sown in flats of peaty earth, which are stored until spring in 

 some protected place, in the manner of stratification boxes. 

 The seeds should be covered lightly, preferably with fine 

 moss. The plants are allowed to grow the first year in the 

 box. 



Crassula. Crassulacece. 



Seeds ; also by cuttings, which should be taken off and 

 laid for two or three days in the sun to dry before planting. 



Crataegus (Haw, Hawthorn). Rosacece. 



Propagated by stratified seeds. Some growers spread the 

 haws in shallow piles in the fall, and allow them to decay, so 

 that most of the pulp is removed before they are stratified. 

 Haws often come irregularly, even from stratified seeds. 

 The varieties are grafted, rarely budded, on common stocks. 



Cress (Lepidium sativum). Cruciferce. 



Seeds, sown at any time of year. See Water Cress. 

 Cress, American. See Barbarea. 

 Cress, Rock. See Arabis. 

 Crinum. Atnaryllidece. 



Increased by seed, sown singly as soon as ripe in three or 

 four-inch pots, in sandy loam and leaf-mould. Place in a
