CHAP. XLII. ROSA CEE. Ro'SA. 783 
DT’ Ile de Bourbon Roses, 38 sorts. ‘ This is a most beautiful section, 
scarcely known in this country. The original, or common, |’Ile 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 Roses, 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 Rosa microphilla, 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 2. 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 2/. 10s. 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 10 ft. 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, Ile 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 putinto large pots, and well furnished with surface manure, and 
plenty of water in summer : their blossoms ought, also, to be cut off just before 
expansion. The crimson perpetual rose may also be forced with fine effect. 
‘The pots (twenty-fours of the London potteries, 8in, 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 is 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
