Leaflets simply serrated, pointed, quite smooth. Sepals pinnate. Fruit ovate, smooth, or rather bristly, like the aggregate flower stalks. Native throughout Europe, and the north of Africa; plentiful in Britain, in hedges, woods, and thickets. Flowers rather large, pale red, seldom white. Fruit, ovate, bright scarlet, of a peculiar and very grateful flavor, especially if made into a conserve with sugar. The pulp of the fruit, besides saccharine matter, contains citric acid, which gives it an acid taste. The pulp, before it is used, should be carefully cleared from the nuts or seeds. A shrub, growing to the height of six feet or ten feet, and flowering in June and July.

Varieties.—There are numerous varieties of this beautiful rose in cultivation, some of which were regarded as distinct species by the earlier authors. The following are quite distinct, and may each be considered the type of a long list of subvarieties.

Var. Noisettiana.The Noisette Rose.—Stem firm, and, as well as the branches, prickly. Stipules nearly entire. Flowers panicled, very numerous, semi-double, pale red. Styles exserted.

This well-known and very beautiful rose is almost invaluable in a shrubbery, from its free and vigorous growth, and the profusion of its flowers, which are continually being produced during the whole summer.

Var. odoratissima.The Tea-scented China Rose.—R. odoratissima, Swt.; R. Indica fragrans, Red.—Has semi-double flowers, of a most delicious fragrance, strongly resembling the scent of the finest green tea. There are numerous subvarieties.

R. Laurenciana  is placed as a species by some authors, but it is probably only a variety of R. Indica.
