March.'] GREEN-HOUSE REPOTTING. 229 



most productive of the gum laudanum, which is secreted 

 about its leaves and branches. The flowers are generally 

 five-petaled, and some of them large and showy ; centre 

 full of stamens. (Soil No. 3.) 



Citrus. This genus contains the most grand and noble 

 of fruit-bearing trees : Loudon says, " The golden apples of 

 the heathens, and forbidden fruit of the Jews, are supposed 

 to allude to this family." They are all handsome ever- 

 green shrubs or trees, bearing highly odoriferous flowers 

 and beautiful golden fruit. In cultivation, the orange fruit 

 is dry and more insipid than in the tropics, but the lemon 

 is far superior in its quality. The varieties of orange are 

 extensive, nearly eighty kinds being cultivated in Italy ; 

 but, with us, the sweet, sour, and rough-skinned are the 

 principal sorts, and more recently we cultivate the manda- 

 rin, otaheitean, and other beautiful dwarf Chinese varieties; 

 also, the striped-leaved varieties of Bergamotte. The lemon 

 are nearly as numerous, though not so apparently distinct ; 

 it is very valuable as a cultivated fruit, and should be in 

 every green-house or conservatory. The lime and the 

 shaddock should not be overlooked, as they are very orna- 

 mental, especially the latter when it arrives at a fruit-bear- 

 ing state. (Soil No. 18, when young plants, and when 

 fruit-bearing keep from it the portion of sand.) 



Clematis, Virgin's Bower. There are only six of these 

 belonging to the green-house, all climbing plants. C. aris- 

 tata and C. brachiata are the best; flowers in racemose 

 clusters, pure white ; foliage small ; and natives of the 

 Cape of Good Hope. The foliage of C. aristata is cord- 

 ate and blotched. Some of the hardy species and varie- 

 ties make beautiful plants for the green-house, such as C. 

 Jlorida, C. sieboldi and P. coeriilea ; they are profuse 

 bloomers and free growers. (Soil No. 3.) 



Clerodendron fragrans multiplex, frequently known 

 under the name of Volkamenia japonica, which is a very 

 different plant, and not supposed to be in this country. It 

 keeps in a good green-house, and flowers well, frequently 

 blooming during winter, and, if planted in the garden dur- 

 ing summer, will flower superbly. The flowers have a 

 delicious fragrance ; if the foliage is rubbed with the hand 

 the smell is not so pleasant. The leaves are large, round,
