Other Species and Varieties of Rosa. — In the cata- Al 
logue of Messrs. Loddiges, 147 species are registered, 632, R. hystrix. 
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 multifléra, 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, 11 ; 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,
