COTONEASTER. 



Dumber and dense habit of growth of | 

 its leaves. It grows best in a poor I 

 sandy or gravelly soil. Other plants I 

 formerly included in this genus are ' 

 now called Dielytra. 



Co'rylus. — Amentacece or Ciqm- 

 lifercT. — The botanic name of the 

 Hazel, Filbert, &;c. The species are 

 generally shrubs ; but C. Colurna, 

 the Constantinople nut, is a large 

 ornamental tree. — See Hazel. 



Cortsa'xthes. — Orchidacece. — 

 Terrestrial orchidaceous plants, from 

 New Holland, which will gi-ow in the 

 open air in England, if protected 

 from frost during winter. They 

 have dark brown flowers, and are so 

 seldom cultivated, that they would 

 not have been mentioned in the 

 present work, had it not been to 

 prevent them from being confounded 

 v/ith Coryanthes, a genus of Stove 

 OrchidacejB from the West Indies. 



Co''sMEA,orCo'sMUS.--Compo5i7ce. 

 — Mexican plants, generally grown as 

 annuals, but which have tuberous 

 roots like the Dahlia, and may be 

 treated like that plant. The flowers 

 are very sho\vy, and of a reddish 

 purple ; and the seeds, when the 

 plants are grown as annuals, should 

 be sown in March and April, in the 

 open ground ; or in autumn, if the 

 young plants can be protected during 

 winter. The plants will grow four 

 or five feet high in any common 

 garden-soil. 



Cotoxea'ster. --i2osaceo5. — Small 

 trees and shrubs, natives of Europe 

 and India, formerly considered to 

 belong to the same genus as the 

 Medlar. They are all well deserving 

 of cultivation in shrubberies, for their 

 bright scarlet or black fruit, and their 

 pretty white or jjink flowers. The 

 Nepal species, C. frUjida, C.affinis, 

 C. acuminata, and C. nunimularia, 

 are the most ornamental. C. rofun- 

 difdlia, and C. microphylla, also | 

 natives of Nepal, are remarkable for 



their thick leathery evergreen leaves, 

 their snow-white flowers, and their 

 profusion of bright scarlet fruit. 

 Both the latter species form dwarf 

 spreading shrubs, and are very orna- 

 mental for a lawn. All the species 

 are hardy, and -nill groM' in any com- 

 mon sod ; and they may all be pro- 

 pagated by seeds, layers, cuttings, or 

 grafting on the common quince or 

 hawthorn . 



CoTTOX Grass. — See ERiorno- 



RUM. 



CoTTLE^DOX. — CrassidacecB. — 

 Navelwort. — Succulent plants, with 

 fleshy leaves, and yellow or red flow- 

 ers, nearly allied to the Houseleek. 

 They should be grown in light earth, 

 mixed with lime rubbish, or in a 

 compost of peat and loam ; and the 

 pots should be well drained. The 

 most ornamental species are natives 

 of the Cape of Good Hope ; and they 

 are propagated by cuttings, which 

 should be laid on a shelf for a few 

 days to dry before they are planted. 

 The European species are scarcely 

 worth cultivating. The plant called 

 Venus' s Navelwort does not belong 

 to this genus, but to Omphalodes. 

 C. Semperva-um Bieb. {Umbilicus 

 Se^npervivum Dec.) is one of the 

 commonest species. 



Co'tula. — Composite;. — Hardy 

 and tender annuals, of which C. 

 aurea L., the flowers of which are 

 like little golden balls, is the only 

 one worth cultivating. It will grow 

 in any common garden soil, and re- 

 quires to be sown in March, with the 

 usual treatment of hardy annuals. 



Cow-itch. — See Muccu'na. 



Cowslip. — Primulacece. — Pri- 

 mula veris, the common Cowslip, is j 

 a weU known British plant, which, | 

 when cultivated in gardens, should be 

 grown in a loamy soil and sheltered 

 situation.
