228 GREEN-HOUSE REPOTTiNO. [March. 



worth cultivating; it blooms profusely from May to July, 

 and has considerable attraction with its brilliant blue spikes 

 of small flowers. (Soil No. 6.) 



Chorizemas, about ten species, foliage very variable ; 

 flowers small and papilionaceous, often very profuse ; colour 

 red and yellow; though small, they are very neat. C. 

 nana and C. ilicifolia are pretty ; but nothing of the kind 

 can exceed C. ovdta and C. Henchmanii, with their beau- 

 tiful scarlet blossoms, which are in great profusion; if 

 grown from seed, they will flower freely the second year ; 

 drain the pots well. (Soil No. 6.) 



Cinerarias, Cape aster, about twelve belong to the green- 

 house. They are herbaceous, or half shrubby, soft wooded 

 plants. C. speciusa, C. amelloldes, (now called Jlgathaea 

 coelestus,) C. purpitrea, and C. lanata, are among the finest 

 of the species; flowers blue or yellow; the latter is con- 

 sidered the handsomest of the genus. The exterior petals 

 are bright purple, and the interior ones white, and, with 

 A. ccelestus, flowers most of the year ; flowers syngenesious 

 and star-like. The herbaceous species must be treated as 

 previously mentioned for that kind of plant. The new 

 hybrids of this genus are rivaling the species, both for 

 beauty of colour and size of flower ; among these are C. 

 Kingii, C. triumphant, C. caslestis, C. ignescens, C. Hen- 

 drs6nia,and V. IVaterhousia. (Soil No. 12.) 



Cinnambmum camphora is the camphor tree of com- 

 merce ; is an excellent evergreen, but has no beauty in its 

 flower. The foliage, when bruised, has a camphorated 

 odour. (Soil No. 10.) 



Cistus, or Rock rose. There are above thirty species, 

 principally natives of Europe, consequently hardy there, 

 and form a great ornament to their gardens, being very 

 abundant and various in flower ; but with us they will not 

 stand the rigour of winter. We have no doubt, however, 

 but, through time, some kinds may be grown that will 

 withstand the greatest cold of the middle states ; they are 

 low shrubby plants, of easy cultivation. C. laduniferus, 

 C. sdlignus, C. populifolius, C. imdulutus, and C.formo- 

 sus, are perhaps the best : the flowers are of short duration, 

 frequently only for one day ; but the quantity makes up 

 this deficiency, being constantly in flower in May and June, 

 and sometimes flower again in autumn. C. creticus is
