- Shrubs or bushes variable in height, natives of Europe, Western Asia, and North America. The leaflets are usually long and lanceolate, especially in the American species; the flowers are of medium size, rosy carmine, and generally produced in clusters, though rarely solitary. The almost spherical fruits ordinarily lose the calyx-leaves on arriving at maturity.

R. cinnamomea, Cinnamon Rose, a European shrub, chiefly inhabiting the mountainous regions of the South, where it attains a height of 9 or 10 feet or more, with a stem occasionally thicker than the arm. The almost straight spines occur in pairs a little below the insertion of the petioles; the leaves are mostly composed of 5 oblong leaflets of a greyish green above and glaucous beneath; and the lilac or very pale carmine flowers are either solitary or two or three together on the same peduncle. This Rose, which has been in cultivation a long time, has given birth to several varieties, single and double, amongst which we may notice the Rose du Saint-Sacrement, still to be seen in some gardens.

R. maialis, May Rose, is a small bush about 3 feet high, from the North of Europe, with weak spines scattered or united in pairs on a level with the insertion of the petioles. The leaves have usually 7 leaflets, ovate or obovate, and slightly glaucous. Flowers small, solitary, pale rose; fruit spherical, orange-coloured, not losing the calyx-leaves on arriving at maturity. This species, formerly more extensively cultivated than now, has given rise to few varieties, which are for the greater part forgotten.

R. rapa, the Turnip Rose - a bush about 4 or 5 feet high, and almost entirely destitute of spines - comes from North America. Leaves of 5 to 9 oblong shining leaflets, assuming a reddish tinge in Autumn. Flowers in clusters, of a bright red, sometimes white, often double even in the wild state. This beautiful Rose, rather rare in France, is frequently cultivated in England, where it is advantageously employed in masses in landscape gardens. The name Turnip Rose probably originated from the resemblance of the spherical fruit surmounted by the leafy calyx-lobes to a turnip.

R. Caroliniana, the Carolina Rose, is also a native of North America, inhabiting marshy ground. A shrub 5 to 10 feet high, remarkable for the length of its stipules and the form of its leaflets, which are oval, acute, dentate, of a deep green above. Flowers in clusters, large, rosy carmine. This, like the foregoing, is common in English collections, and is equally effective in clumps.
