Mr. Rivers also informs me that he raised two or three roses of the Provence class from seed of the old single moss-rose; and this latter kind was produced in 1807 by bud-variation from the common moss-rose.

The Single Moss and Single Lilac Moss are desirable as being distinct, and capable of bearing seed from which new varieties may be raised.

If it had any claims to be ranked as a botanical species, the single-flowering Moss Rose would most probably have been the first known and described; but the single moss, as compared with the double, is a new variety. The year 1724 is recorded by botanists as the date of its introduction, or rather of its being first noticed in Europe, and Miller mentions it in 1727.

Although the moss rose appears to be a plant of so short an existence, its birth place is not satisfactorily known; but from all the accounts we can collect of its register, it appears to be a fortuitous child of England, as we have numerous accounts of its having been exported, but none of its importation into this island, nor has it been discovered elsewhere, except in a state of cultivation. Messrs. Lee and Kennedy, of Hammersmith have, a few years since produced a perfectly single moss rose, which they pronounce to be only a variety of the common Provins rose. We must therefore conclude that the moss-like pubescence of the calyx and young branches, is owing to some accidental circumstance which this climate produces, as we are told that this variety loses its mossiness, almost immediately when planted in Italy, and we have not yet heard of this rose having been in any instance raised from seed, for the single moss rose was reduced to that state from the double variety (either accidentally or intentionally) by a peculiar mode of cultivation. The single variety of the moss rose, as well as the double white moss rose, still continue scarce, and bring high prices to the nurserymen near London.

A Description of Roses. By Mr. T. Rivers, jun., Nurseryman, Sawbridgeworth, Hertfordshire.
In attempting a descriptive catalogue of Roses, I hope to be excused errors, which it seems almost impossible wholly to avoid. Roses vary so much in their form and colour in different seasons and situations, as sometimes scarcely to be recognised... what I hope to accomplish is, to give an idea of what they ought to be in form and colour, under favourable circumstances of soil and situations; and where there is so much confusion as at present in the names and arrangement of Roses, to be among the first in attempting a correct nomenclature.
MOSS ROSES.
Single, bright rose colour, expanded and large.

The following terms are used to express the form of the Flower:
Expanded.—The flower rather flat, petals open, in some varieties, showing the central stamens.
