 by sc. bracts (syns. Thibaudia and Proclesia 

 acuminata).

CEANOTHUS. (MOUNTAIN SWEET OR 

 KED ROOT.) 



Description. Very beautiful hardy, half-hardy, 

 or greenhouse shrubs (ord. Khamnese), the 

 hardier species and their varieties being very orna- 

 mental on warm, sunny walls. They are generally 

 deciduous, but in the greenhouse some retain their 

 leaves. The individual flowers are small, but are 

 pro.luced in considerable numbers together, and 

 thus are very effective. Many named forms have 

 been raised within recent years. 



Propagation. Some of the species may be 

 raised from seeds sown as soon as ripe, or in 

 spring, in a warm house ; the whole by cuttings 

 of young wood struck under glass in a little heat 

 in autumn ; or, preferably, by layers. 



Soil. -A good, dry, rather porous soil is the best 

 for the hardy and half-hardy species grown out- 

 doors, but those grown under glass may have one 

 of a richer nature. 



Other Cultural Points. Although the outdoor 

 Ceanothuses require a dry soil, they must not be 

 allowed to suffer in dry weather while making 

 growth, or when in bloom ; good soakings of water 

 may be given at intervals. On walls they ought to 

 be pruned in April, or a little sooner in early 

 districts. When the allotted space has been 

 covered, cut the shoots back to two or three eyes 

 for the production of young wood, on which the 

 flowers appear, except in the case of those species 

 which flower on the previous year's wood. Most of 

 the Ceanothuses should have some protection, sucli 

 as a mat, in severe weather. 



Principal Species : 



americanus, 5', Je., Jy., wh. Among the 

 hardiest.. The var. variegatus has Ivs. variegated 

 with yel. (syn. intermedius.) 



azureus, 1(X, Je., Jy., pale bl. One of the best 

 and fairly hdy. Good vars. of azureus are Albert 

 Pittet, albidus, Gloire de Versailles (very reliable), 

 Marie Simon, and Othello. 



dentatus, 10', My., bl. Desirable, though gener- 

 ally needing protection (syn. lobbianus). 



veitchianus, 9', Je., bl. A pretty and useful 

 species. 



Other Species : 



cuneatus, 4', Je., hlf- 



hdy., bl. (syns. verru- 



cosus and macrocarpus) . 

 divaricatus, 4', Jy., pale 



bl.

(*./. Fenollei). 

 floribundus, 4', Jy., bl. 

 mtegerriinus, 6', Jy., hlf-

fornicus and neva- 



densis). 



Cayenne (see Capsicum).

(syn. fontanesianus). 

 papillosus, 3'. Je., hlf- 



hdy., bl. 

 prostratus, 3', bl. 

 rigidus, 6', Jy., hlf. hdy., 



bl. 

 thyrsiflorus, 9', Jy., hlf- 



hdy., bl. 



CECROPIA. 



A small genus (ord. Urticacese) of handsome 

 stove evergreen trees, whose economic value lies 

 in the indiarubber which is obtained from some of 

 the species. The flowers are borne in catkins. 

 They grow admirably in a mixture of loam and 

 peat, with coarse sand. Cuttings of ripe wood 

 root readily in very sandy soil under a bell-glass 

 over bottom heat. 



Principal Species : 



concolor, 20', Mch. palmata, 25', Mch. 



frigida, 12', Mch. peltata, 30', Mch. 



CEDAR. 



The Cedar of Lebanon is Cedrus Libani (which 

 will be found under Cedrus), the Prickly Cedar is 

 Cyathodes acerosa, and the name Sharp Cedar is 

 applied both to Juniperus Oxycedrus and Acacia 

 Oxycedrus. The Barbadoes or Bermudas Cedar is 

 Juniperus bcrmudianus. 



CEDRELA. 



A genus (ord. Meliaceoc) of stove trees. The 

 fragrance of the wood resembles that of the Cedar. 

 Odorata is known as the West Indian Cedar. 

 They thrive well in sound loam and leaf mould, 

 and may be increased from cuttings in heat under 

 a glass. 



Toona, 55', Je., wh., pk. 

 velutina (now Chkkrassia 

 tabularis) . 



Principal Species : 



australis, a form or *yn. 



of Toona. 



odorata, 50', Jy., pk., wh. 

 sinensis (HI/H. Ailautus 



flavescens) . 



CEDRONELLA. 



With one exception (triphylla) the species of 

 this genus (ord. Labiata;) are herbaceous per- 

 ennials, and thrive best in the greenhouse. A 

 compost of loam and peat suits them admirably, 

 and propagation may be effected by division of 

 the roots. 



Principal Species : 



cana, 3', Je., red, crim. 

 cordata, 1', Jy., lil. 

 mexicana, 25', Jy., pale 



pur. 



pallida, 2', Sep., ro. 

 triphylla, 3', Jy., pale 



pur. This is a grh. ev. 

 shr., and must be in- 

 creased from cuttings in 

 sandy soil ; by some 

 authorities it is now re- 

 ferred to canarieusis. 



CEDRUS. (CEDAR.) 



Description. Majestic Coniferous trees, which 

 form conspicuous features in favourable situations 

 in this country. Cedrus Libani is the scriptural 

 Cedar of Lebanon, so familiar to all readers. It 

 is very imposing when it attains a large size, with 

 its spreading habit at the top, and its massive 

 branches. There are many specimens in this 

 country over 50' high, and one at Strath fieldsaye, 

 Hants, is said to be 120' high. It is perfectly 

 hardy. Atlantica, the Mount Atlas Cedar, is of 

 even more value for ornamental planting, its 

 glaucous foliage rendering it very conspicuous and 

 pleasing; while its pyramidal habit, not so pro- 

 nounced as to be stiff, greatly adds to its beauty. 

 It is the best of the three species for general 

 planting. Deodara, the Deodar or Indian Cedar, 

 from north-west India, is also a noble tree, al- 

 though less hardy than the foregoing. Its form 

 is very handsome, and the lower branches in good 

 specimens are of great length, and cover a large 

 space.
