1. The Bourbon, the varieties of which are easily known by their luxuriant growth, and thick, large, leathery leaves. These are, moreover, reasonably hardy.
2. The China.—This includes the present China, Tea, and Noisette Roses, which are now much confused, as there are many among the Teas which are not tea-scented, and among the Noisettes are those which do not bloom in clusters; they are, moreover, so much alike in their growth and habit, that it is better each should stand upon its own merits, and not on the characteristics of an imaginary class.
3. Musk.—Roses of this class are known by their rather rougher foliage.
4. Macartney.—The varieties of this are distinguished by their very rich, glossy, almost evergreen foliage.
5. Microphylla.—A class easily distinguished by their peculiar foliage and straggling habit.
The third general head we divide again into five classes:
1. Garden Roses.—This includes all the present French, Provence, Hybrid Provence, Hybrid China, Hybrid Bourbon, White, and Damask Roses, many of which, under the old arrangement, differ more from others in their own class than from many in another class.
2. Moss Roses, all of which are easily distinguished.
3. Brier Roses, which will include the Sweet-Brier, Hybrid Sweet-Brier, and Austrian Brier.
