March.] GREEN-HOUSE REPOTTING. 223 



C. rigidun, bright blue ; the two latter are very profuse in 

 their flowering. (Soil No. 6.) 



Oestrum; a genus of about ten species; some of them very 

 popular under the name of Night-blooming Jasmine ; which 

 are C. nocturnum and parquii with long greenish-white 

 flowers ; C. diurnam, pearly white, the centre of the flower 

 sparkling like a diamond; C. aurantiacum, dark orange 

 flowers in large clusters, very handsome, blooming in winter. 

 (Soil No. 12.) 



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 0. 

 ilicifolia are pretty ; but nothing of the kind can exceed C. 

 ovata and C. varium with their beautiful scarlet and orange 

 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. speciosa, C. amelloides (now called Agathcca 

 cwlestui}, C purpurea, and C. lanata, are among the finest 

 of the species; flowers blue or yellow; the latter is considered 

 the handsomest of the genus. The exterior petals are bright- 

 purple, and the interior ones white, and, with A. ccetestus, 

 flowers most of the year ; flowers syngenesious and star-like. 

 The herbaceous species must be treated as previously men- 

 tioned for that kind of plant. The new hybrids of this genus 

 are rivalling the species, both for beauty of colour and size of 

 flower; among these are Kingii, Scottii, Catherine Hayes, Lady 

 Campbell, Madam Sontag, Jenny Lind, Rosy Morn, Vicar of 

 Wakefield, and several others, all really beautiful. They 

 require frequent repottings and plenty of moisture whilst in 

 a growing state. (Soil No. 12.) 



Cinnamomum camphbra is the camphor tree of commerce; 

 is an excellent evergreen but has no beauty in its flower. 

 The foliage, when bruised, has a camphorated odour. (Soil 

 No. 10.) 



Cistus, or R,ock 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
