crocks to begin with, then the plant should be set on a layer of moss, 

 and the roots packed in with peat and Sphagnum in the proportion 

 of 2 and i respectively. Repotting may be done every other year, 

 and the best time is when roots begin to push from the young 

 growths. They like a winter temperature of 55 to 65, and a 

 spring heat of 60 to 70. An airy house is required, with light 

 shade in summer. They must have abundance of water while grow- 

 ing, but only enough to prevent the pseudo-bulbs from shrivelling 

 in the resting period. They may be increased by division when 

 fresh growths start. There is considerable variation in height and 

 habit among Cattleyas. Of recent years many hybrids have been 

 raised, both specific and generic. Cattleyas have been crossed with 

 Laelias, and also with Brassavolas (see Brassocattleya and Brasso- 

 catlaelia). The following are the principal species ; for the hybrids, 

 of which there are large numbers, specialists should consult a 

 standard book on Orchids : 



Aclandiae, 6 ins. high, late spring. 



citrina, 6 ins. high, spring. 



intermedia, 15 ins. high, spring. 



labia^a vera, 12 ins. high, autumn. 



Lawrenceana, 9 ins. high, spring. 



Loddigesii, 15 ins. high, late summer. 



Mendelii, 1 5 ins. high, late spring. 



Mossiae, 1 5 ins. high, late spring. 



Schilleriana, 6 ins. high, spring. 



Skinneri, 10 ins. high, spring. 



Trianae, 15 ins. high, winter. 



Warscewiczii (gigas), 15 ins. high, early summer. 



Cauliflower. See Brassica and Kitchen Garden. 



Ceanothus (ceano-thus, from keanothus. Ord. Rhamneae). 

 Beautiful shrubs, the most useful of which are the hardy deciduous 

 kinds, such as americanus, white, and its variegated variety; 

 azureus, blue, and its fine variety Gloire de Versailles; dentatus, 

 blue; and Veitchianus, blue; inasmuch as they can be utilised for 

 house walls. All flower in late spring or early summer. They like 

 a sunny aspect, and ordinary soil that is not heavy and damp. 

 They may be planted in autumn or late winter. Propagation is by 

 layers, or by cuttings of side shoots in sandy soil under a bell-glass 

 in August. Few wall plants are capable of making a more charming 

 picture on a dwelling than a healthy Ceanothus. 



Cedar, Cedrus (ce-dar, ce-drus, from kedron, or from Cedron, a 

 brook in Judea. Ord. Coniferae). The Cedar of Lebanon is Cedrus 

 Libani, an impressive tree. The Mount Atlas Cedar is C. atlantica; 

 and the Deodar or Indian Cedar is C. Deodara. All are hand- 

 some, and not the least so is atlantica, which has a pyramidal habit. 

 There are several horticultural varieties of each of the species named. 

 A deep, well-drained sandy soil is best. Stiff, cold clay is unsuitable. 



Celandine. The Greater Celandine is Chelidonium majus, and 

 the Lesser Celandine is Ranunculus Ficaria. Both are British 

 wildings.
