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.
Miniature (Rivers's), bright crimson colour, cupped, very small and semi-double.

The following terms are used to express the form of the Flower:
Cupped.—The outer row of petals erect, rather incurved, enclosing numerous smaller petals; the crimson perpetual Rose when first open will illustrate this term.
