Ceroxylon 



Chalk 



CEROXYLON. 



Tliis is a small genus of stove Palms (ord. 

 Palnne), the wax of which is used by the people of 

 New Grenada in candle making. Plants are raised 

 from seeds, and grown in good loam. 



Principal Species : 



andicoluin, 50'. About 8' in this country. 



CESPEDESIA. 



Small trees (ord, Ochnaceie), natives of America, 

 which should be grown in the stove. They 

 succeed best in a compost of fibrous loam and 

 peat, with sand and charcoal to ensure porosity, 

 and may be propagated from cuttings in sandy 

 soil beneath a bell-glass over bottom heat. 



Principal Species : 



Bonplandii, (>', sum., or. yel. 



CESTRUM. 



This genus (ord. Solanaceas) is well Known to 

 most horticulturists by the name of Habrothamnus. 

 It comprises half-hardy, greenhouse, and stove 

 plants, some of which are very handsome. The 

 berries of all the species are poisonous, and what 

 economic value the genus possesses lies in the dye 

 that is manufactured from tinctorium. As pillar or 

 wall plants in a greenhouse or conservatory many 

 arc extremely beautiful. The culture is easy, 

 ami they will gmw in any soil, though a mix- 

 ture of loam and peat is most suitable. Prop- 

 agation is easily effected by cuttings. A severe 

 annual pruning is necessary after flowering.

CETERACH (< ASPLENIUM). 



CH.<ENACTIS. 



Hather showy plants (ord. Composite), of which 

 there is only one species in cultivation in this 

 country. This is tenuifolia, which grows 9" or 12" 

 high, and has yellow flowers in summer. Its 

 hardiness is doubtful, and it ought to be kept in a 

 frame in winter. Seeds should be sown in a frame 

 Or greenhouse in early spring. Sandy soil.

prises one annual species, which is raised from 

 seeds sown in boxes or pots in the ordinary 

 manner, and planted out of doors when the 

 weather is favourable ; and a number of herbaceous 

 perennial species, which are increased by cuttings 

 in late summer, and can also be employed for 

 summer bedding. Most of the species have been 

 gro%vn under the generic title of Manulea.

CH^ROPHYLLUM. 



Interesting hardy plants (ord. Umbellifenc), 

 mostly annual or biennial. They may be raised 

 from seed sown either in a cold frame or in the 

 open ground. Ordinary garden soil will suit them. 



Principal Species : 

 aromaticum, 3', Jy., wh. villosum, 2', Jy., wli. 



CH^ETANTHERA. 



There are only a few species in this genus (ord. 

 Compositae) of Chilian "plants. They are herb- 

 aceous perennials, thriving best in the cold green- 

 house in a mixture of loam and peat. Propagate 

 by division early in the year.

CH^TOCALYX. 



These stove evergreen twiners (ord. Leguminosfe), 

 which came from St. Vincent, thrive in a compost of 

 loam and peat or leaf mould, and may be prop- 

 agated from cuttings inserted in sandy soil under 

 a bell-glass. 



Principal Species : 



vincentina, G', Je., yel. (syn. Glycine vincentina). 



CHAILLETIA. 



These shrubs (nrtl. Chnilletiacese) are found 

 chiefly in tropical South America. One species, 

 toxicaria, comes from Sierra Leone, and its 

 poisonous seeds are used as rat poison. Under 

 cultivation stove treatment is necessary to ensure 

 strong growth, but a warm greenhouse will suit 

 during most of the year. Propagation by cuttings ; 

 use peat and loam for potting.

CHALK. 



From a gardener's point of view, chalk (car- 

 bonate of lime) is valuable because of the power 

 it has of neutralising the acidity of wet, sour 

 soils, thus rendering them fertile, but it must be 

 remembered that even in this respect lime is 

 more valuable than chalk, for the latter, when 

 pure, contains a little more than half its bulk of 

 lime. Kor the bottoms of walks and for the 

 formation of drains, in place of tiles or faggots, 

 chalk is useful. Not a few plants are benefited 

 by having lime in the soil, but where this is not 

 readily obtainable chalk may be substituted.
