Rivers' s Catalogue of Roses. 509 



Art. IV. A netv Descriptive Catalogue of Roses. By T. Rivers and 

 Son, Nurserymen, Savvbriclgeworth, Herts. In one imperial folio 

 sheet, for sending as a single letter by post. 



We have before strongly recommended this catalogue (IX. 

 458.); and the present new edition of it is considerably en- 

 larged and improved. The following extracts will show the 

 arrangement, as well as record some valuable remarks on the 

 culture of the different divisions : — 



Moss Roses, 17 sorts. " Most of the varieties prefer a cool soil, though 

 Mossy de Meaux is, perhaps, an exception, as it seems to flourish better in 

 light dry soils. The White moss, unless budded on the dog rose (Rosa 

 canina) will not, in general, grow well; its sickly appearance in some situ- 

 ations may be often traced to its being worked on some improper stock. If 

 on its own roots, in rich soils, it will often change to pale blush. All are well 

 adapted for standards; but, to have them in perfection in warm dry situations, 

 in March put round each stem, on the surface of the soil, the fourth of a 

 barrowful of manure ; on this place flints or moss, to take oiF its unsightly 

 appearance, and make a little ornamental mound. This treatment will keep 

 the soil cool, and make them bloom in a most superior manner, even in situ- 

 ations previously thought to be most ungenial to their culture. The manure 

 should be spread on the surface in November, and lightly forked in." 



Perpetual Roses, 2Q sorts. " These, with the exception of Perpetual Scotch, 

 Stanwell perpetual, and Pompone four seasons, are all varieties of i?osa 

 damascena, or the Damask rose. They are, perhaps, the most deairable of all 

 the pleasing families of 7?osa. Like their prototype, they are highly fragrant, 

 and, if possible, more so in September, October, and November, tnan in June. 

 As every shoot in most of the varieties produces bloom, the soil cannot be too 

 rich ; for, with these, luxuriant growth will be sure to give abundance of 

 flowers. A good practice would be to cut off all the bloom-buds in June, and 

 shorten the shoots to about half their length ; then water them with manured 

 water in July and August ; this will make them shoot and bloom most lux- 

 uriantly all the autumn." 



Hybrid Roses, 66 sorts. " The varieties of this distinct family are prin- 

 cipally between the China rose (.ffosa indica) and Rosa gallica. They are all 

 very beautiful and distinct, and have that pleasing, glossy, sub-evergreen 

 foliage, peculiar to the China rose; but make a great deviation from that 

 family, in not being perpetual bloomers. In this division are some of the 

 most beautiful roses known ; and among them George the Fourth^ raised from 

 seed by T. Rivers, jun., may rank among the best. These are also all very 

 robust, and will grow and bloom well in the most unfavourable rose soils. 

 Their peculiar habit and vivid colours render them particularly well adapted 

 for standards." 



Select Roses, 70 sorts. " In this division are many varieties of .^dsa gallica, 

 and also many hybrids between R. gallica and R. centifolia, &c. &c. The 

 varieties selected are all fine and distinct, and will be found well worth cul- 

 tivation." 



Varieties ofHosa alba, 9 sorts. 



Provence Roses, 16 sorts. " The Provence rose is the .Kosa centifolia of 

 botanists, the Cabbage rose of the English gardens, and the Rose a cent feuilles 

 of the French. All its varieties are extremely fragrant, and some very beau- 

 tiful. The Provence rose of the French catalogues is our Rosa gallica." 



Noisette Roses, 44 sorts. " This division, with the Perpetual roses, will 

 ultimately be the ornament of every British garden : the astonishing mul- 

 tiplicity and constant succession of flowers (till the chills of November prevent 

 the opening of the buds) make them highly interesting, They are all very
