Other Species and Varieties of Rosa. In the cata- 

 logue of Messrs. Loddiges, 147 species are registered, 

 of all of which, with one or two exceptions, there are living plants. The 

 garden varieties in the same collection amount to about 1500. There is 

 indeed no end to the garden varieties, new ones being every year raised 

 from seed, and old varieties every year disappearing. New species are also 

 occasionally introduced, and several have been lately raised in the Hort. 

 Soc. Garden from Himalayan seeds. For species we recommend the cul- 

 tivator to have recourse to the collection of Messrs. Loddiges, and for garden 

 varieties to the most fashionable nurserymen of the time. In Rivers's Abridged 

 List of Roses, 1840, he recommends, as a selection for small gardens : Pro- 

 vence roses, 7 ; moss roses, 8; hybrid Provence roses, 7 ; hybrid China roses, 

 20; French roses, 16; Rosa alba, 9 ; damask roses, 6; Scotch roses, 8; 

 sweet briars, 5 ; Austrian briars, 2; Ayrshire roses, 6 ; Rosa multiflora, 3 ; 

 evergreen roses, 7 ; Boursault roses, 4 ; Banksian roses, 2 ; hybrid climbing 

 roses, 4; perpetual roses, 12; Bourbon roses, 7; China roses, 15 ; tea-scented 

 roses, 1 1 ; miniature roses, 5 ; Noisette roses, 12 ; musk roses, 3 ; Macartney 

 roses, 3 ; .Rosa microphylla, 3. In all, 185 sorts ; which would form a very 

 efficient rosarium. 



Soil and Situation adapted for Roses. 



The common wild roses will grow in very poor soil, provided it be dry; 

 but all the cultivated sorts require a soil naturally light and free, and more or 

 less enriched. The situation should be open and airy, exposed to the east, 

 or, in warm situations, to the north, rather than to the south ; because the 

 intensity of the sun's rays Accelerates too rapidly the expansion of the flowers, 

 and also diminishes the colour and fragrance of the petals. A rose-garden,
