This fine Marbled Variety of the _spinosissima_ is certainly much more desirable than its original, but is by no means so abundant; and we think it is a smaller or more dwarf-growing plant: but not having seen more than two plants of it in bloom, we cannot be quite certain of its character in that particular. The flowers are somewhat smaller than in the White, and one of the specimens in bloom at the nursery of Malcolm and Co., Kensington, still smaller than our figure of it, but fully equal in beauty and richness of colour to the plant from which our figure was made at the nursery of Messrs. Loddige, Hackney; but so variable are the Striped and Marbled Roses, that we cannot expect them often to stand the test of comparison. It is an early blooming Rose, but not of long duration; beginning to flower the latter end of May, and seldom lasting more than three weeks. [Illustration] ROSA nana, _minima_. _Smallest Dwarf, or True Pompone Rose._ CHARACTER SPECIFICUS. ROSA, germinibus subrotundis; floribus minutis, incarnatis, in medio profunde rubris; foliolis ovatis, acutis, et parvis, subtus villosis, marginibus serrulatis, glandulosis. Frutex pygmæus; caule et petiolis aculeatis; aculeis ramorum sparsis, rectis. SPECIFIC CHARACTER. ROSE, with roundish seed-buds; flowers very small, flesh-coloured, and of a deep red in the centre; leaflets egg-shaped, sharp-pointed, and small, hairy beneath, with finely sawed glandular margins. It is a dwarf shrub; stem and petioles prickly; the spines of the branches are scattered and straight. * * * * * This elegant little plant proves, as we imagined it would, distinct from the minor variety, whose flower and leaves we find subject to vary both in size and colour, but in the present true original species they are not. At present it is a very scarce Rose, and likely so to continue, from the difficulty annexed to its cultivation. Our figure represents one-third of the entire and only plant in the collection of Messrs. Loddige, Hackney, the whole plant exhibiting an equal degree of luxuriant bloom. It very rarely attains the height of one foot; but this year it had not exceeded five inches, which gave an addition of singularity to its appearance. It begins to flower nearly at the same time as the Rose de Meaux, but does not remain quite so long in bloom. [Illustration] ROSA semperflorens. _Ever-blowing Rose._ CHARACTER SPECIFICUS. ROSA, germinibus subrotundis, pedunculisque læviter hispidis; floribus profunde rubris, semperflorentibus; petiolis aculeatis; foliolis oblongis, acuminatis, glabris; caule viridi, glabro, ad basin spinoso. SPECIFIC CHARACTER. ROSE, with roundish seed-buds, and slightly hispid peduncles; flowers of a deep rich red colour, ever-blooming; petioles prickly; leaflets oblong, sharp-pointed, and smooth; stem green, smooth, and thorny towards the base.
