780 ARBORETUM AND FRUTICETUM. PART III. 
cultivation. If a Rosarum Monographia, like that of Dr. Lindley, and a 
descriptive classification like that of the Nouveau Du Hamel, were to be made 
every seven years, though they might remain nearly the same with regard to 
the leading divisions, or types, of the varieties, they must necessarily be much 
changed in the details; owing to numbers of the varieties being almost 
annually lost, going out of repute, or actually changing their appearance from 
time and local circumstances ; and from others being originated from seed, or 
becoming, from accidental circumstances, favourites with the public. Hence 
it is, that, whoever would wish to procure the best collection or selection of 
roses which are in existence at the time being, must resort to the latest and 
best Catalogue of Roses then actually in cultivation. Such a catalogue for 
Britain, in the year 1836, is that of Messrs. Rivers and Son of the Sawbridge- 
worth Nursery, Hertfordshire, from which we make the following extracts ; 
recommending the catalogue itself (which, being a single sheet, can be sent by 
post to any part of the world) to those who wish the names of the sorts, and 
other particulars respecting them, in detail. The prices of the common 
kinds of roses in Messrs. Rivers’s catalogue vary from Is. to 3s. 6d. for dwarfs, 
and from 3s. 6d. to 5s. for standards ; some varieties, which are rare, being from 
7s. 6d. to 10s. 6d. each. The best plan for getting a good selection, in our 
opinion, is, to order a given number of sorts from each section, not to exceed a 
limited price per plant, or for the total number. When particular sorts are 
ordered by name, it may frequently happen that the plants of that sort are 
weak, or, from scarcity, dear; whereas, when a discretionary power is left 
with the nurseryman, if he is a man of character, he can always do more for 
his customer, than the customer can do for himself. 
Moss Roses, 24 sorts. Messrs. Rivers’s “collection of moss roses comprises 
many that are very beautiful and distinct ; and some, perhaps, only fit for those 
amateurs who think that all moss roses are beautiful: one step further 
towards a dark crimson moss is made in the rouge du Luxembourg, 
which is very beautiful, and a most luxuriant grower. Most of the varieties 
prefer a cool soil, though the 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 (#o6sa canina), will not, in general, grow well: its sickly ap- 
pearance, in some situations, 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 off 
its unsightly appearance, and make a little ornamental mount. This treat- 
ment will keep the soil cool, and make them bloom in a very superior man- 
ner, even in situations previously thought to be most ungenial to their culture. 
The manure should be spread on the surface in November, and lightly 
forked in.” 
Provence, or Cabbage, Roses, 25 sorts. ‘The Provence Rose is the R. pro- 
vincialis of Miller’s Gardener’s Dictionary, the R. centifdlia of modern 
botanists, and the Rose 4 Centfeuilles of the French. Thisis a most distinct 
and elegant family, and excessively fragrant. The footstalks of the flowers 
are slender, and the flowers large; so that, when in bloom, the plant has a 
peculiarly pendulous and graceful appearance. The moss rose is evidently a 
variety of this, as I have raised seedlings from the single moss which have 
lost all their mossy appearance, and have returned to the habit of the Pro- 
vence rose.” 
Perpetual, or Autumnal, Roses, 50 sorts. “ The perpetual, or autumn-flow- 
ering, roses are, perhaps, the most desirable of all the sections of the genus : 
they are highly fragrant, and, if possible, more so in September, October, and 
November, than 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 to shorten the shoots to about half their length ;
