intended to be grown as objects of superior cultivation, on 

 the other hand, they require to be frequently topped to 

 produce a bushy growth ; and. this requires very close atten- 

 tion, for they grow rapidly. The proper soil is three parts 

 peat earth to one of sandy loam, with more or less sand 

 added, the other materials being turfy. The pots must be 

 well drained, and the plants watered with care at all seasons. 

 Besides several handsome species, the varieties of Correa 

 raised from seeds are now very numerous, and some of them 

 far excel the original kinds. C. alha, C. pulcliella, C. speciosa, 

 C. virens ; but the garden varieties are endless. 



CORTUSA. Bear's-ear Sanicle. [Primulaceae.] A 

 pretty dwarf herbaceous perennial, suitable to be grown on 

 rockwork, or in pots among alpine plants. Loam and peat. 

 Propa.^ated by division. 



CORYDALIS. [Fumariace^.] Pretty hardy plants, of 

 easy culture in common soil. The annuals and biennials, 

 which are the least important, may be sown in the borders in 

 April and June. The perennials are increased by division. 



CORYPHA. Fan Palm. [Palmace^e.] Beautiful palms. 

 Most of this family will succeed in a warm greenhouse. Rich 

 sandy loam. Propagated by imported seeds. The chief one 

 is C. australis. 



COSMANTHUS. [Hydrophyllacege.l Pretty hardy annuals. 

 Rich garden soil. Increased by seeds. 



COSMEA. [Compositag.] Pretty half-hardy annuals and 

 perennials. Rich garden soil. The annuals increased by 

 seeds, which should be sown in gentle heat in spring, and the 

 young plants turned out in May ; the perennials by root 

 division. Also called Cosmos. 



COSMELIA. [Epacridaceae.] Greenhouse evergreen 

 shrub. Sandy peat. Propagated by cuttings in sand under 

 a bell-glass. The only one we grow is C. rubra, flowers red, 

 in Mav. 



COtONEASTER. [Pomaceae.] Hardy trees and shrubs, 

 of an ornamental character. Common soil. Increased by 

 layers or by seeds. The deciduous and tree-like sub-evergreen 

 species are less desirable than the prostrate trailing ever- 

 green shrubs with neat box-like foliage. There are many 

 varieties.
