221 GREEN-HOUSE REPOTTING. [March. 



time, some kinds may be grown that will withstand the great- 

 est cold of the Middle States; they are low shrubby plants, 

 of easy cultivation. C. ladaniferus, C. salignus, C. populifo* 

 tins, C. undulatus, and C. formosus, 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 most productive of the gum laudanum, 

 which is secreted about its leaves and branches. The flowers 

 are generally five-petalled, 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; Louden says, "The golden apples of the 

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

 allude to thas family." They are all handsome evergreen 

 shrubs or trees, bearing highly odoriferous flowers, and beau- 

 tiful golden fruit. In cultivation, the orango fruit is dry 

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

 superior in its quality. The varieties of orange are exten- 

 sive, 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 mandarin, Otahei- 

 tan, 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 ornamental, especially the 

 latter when it arrives at a fruit-bearing 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. (7. aris- 

 tdta and C. brachidta 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 cordate and 

 blotched. Some of the hardy species and varieties make 

 beautiful plants for the green-house, such as florida, Sieltoldii, 

 and ccerulea; they are profuse bloomers, and fine growers.

 known under the name of Volkamenia Japonica, which is *
