CHAP. XLII. 



Ulle de Bourbon Roses, 38 sorts. " This is a most beautiful section, 

 scarcely known in this country. The original, or common, Hie de Bourbon 

 rose was sent to France, in 1822, from the Mauritius, by the brother of M. 

 Noisette, a nurseryman at Paris. It is semidouble, and seems to have the 

 characters of a distinct species. It bears seeds in great profusion ; but, though 

 thousands of seedlings have been raised, the produce of good varieties has 

 been but in small proportion to the bad. Like the China roses, of which they 

 have been considered a division, they are perpetual bloomers ; but they have 

 a luxuriance and gracefulness quite their own. The perfect and elegant form 

 of their flowers, the extremely delicate tints in some, and vivid rose-colour in 

 others, will soon establish them in the favour of the rose amateur : as stan- 

 dards, they grow most luxuriantly, are quite hardy, and bloom in greater 

 perfection late in autumn than any other perpetual rose." 



Musk Rows, 10 sorts. " These are interesting from their powerful fra- 

 grance and autumnal flowering. The old white is one of the oldest inhabitants 

 of the English gardens." 



Macartney Roses and TCosa microphylla, 10 sorts. " Most of the annexed 

 varieties of this interesting section are novelties. From their evergreen, shin- 

 ing, neat foliage, and elegant growth, they are quite worthy a place in the 

 garden of the rose amateur. In cold soils, they will require a warm situation 

 and raised border: but they are much hardier worked on the dog rose; and, 

 as half standards, are beautiful ; requiring the same treatment as standard tea- 

 scented roses." 



Sweet Briar, 17 sorts. 



Scotch Roses, 27 sorts. " These are all derived from the R. spinosissima, 

 or wild rose of Scotland ; and they form so gay an assemblage among May 

 flowers, that a clump or border ought to be devoted to them in every flower- 

 garden. The shape of the flower is peculiar and similar, being nearly 

 globular." 



Miscellaneous Roses, sold at 21. IQs. per 100, in pairs ; 101 sorts. 



Mr. Rivers has also given a synopsis of variegated roses, consisting of 42 

 sorts. He adds that the sections " of roses are now so well defined, that 

 each ought to have its department : a clump of hybrids, for their gorgeous 

 colours in June and July ; of perpetuals, for their fragrance in the autumnal 

 months ; of Noisettes, for their elegance and abundance of flowers ; of Scotch 

 roses, for their precocity and humble growth ; and of climbing roses, for pillars, 

 which should be planted in a very rich soil, as they will then put forth strong 

 central branches, of 8 ft. or 10ft. in length, which, when fastened to the 

 stakes, will furnish a plentiful supply of lateral blooming shoots for many sea- 

 sons. Climbing roses will cover a sloping bank, as their flexible branches 

 can be pegged to the ground in any direction, and will form a beautiful carpet 

 of foliage and flowers ; the dark crimson and white varieties blending with 

 peculiar elegance. The perpetual, He de Bourbon, and Noisette roses, from 

 their vigorous habits and tendency to flower, may be made fine objects for 

 ornamenting halls, &c., during the autumnal months; for this purpose, they 

 should be put into large pots, and well furnished with surface manure, and 

 plenty of water in summer : their blossoms ought, also, to be cut offjust before 

 expansion. The crimson perpetual rose may also be forced with fine effect. 

 * The pots (twenty-fours of the London potteries, Sin. deep, 7 in. over) 

 must be plunged in the natural soil to the rims, a deep frame placed over 

 them, and the heat kept up with linings of hot dung,' giving air as required. 

 This fine autumnal rose, when forced, and blooming in March or April, is 

 most beautiful : its too short flower stalks are lengthened by this mode of 

 culture; its flowers are erect (unlike many other forced roses), and lose none 

 of their colour or fragrance by the excitement they have undergone. For all 

 these purposes" Mr. Rivers adds, " roses should be * worked ' on the dog rose 

 stock, as its vigorous and easily excitable habit are quite necessary to bring the 

 plants into a fit condition for forcing." 



Geography. The rose, in some of its forms, is found in a wild state in
