R. BIFLORUS.--Himalayas, 1818. A tall-growing species with whitish, spiny stems, and simple three-lobed leaves that are tomentose on the under sides. The flowers are thickly produced, pure white, and render the plant highly attractive, and of great beauty. R. DELICIOSUS.--This Rocky Mountain Bramble (1870) is a very worthy species, with three or five-lobed (not pinnate) leaves, and large, pure white flowers that are each about 2 inches in diameter, and produced in profusion from the leaf-axils. For ornamental planting this may be placed in the first rank of the family to which it belongs. R. FRUTICOSUS.--Common Bramble, or Blackberry. Of this well-known native species there are several worthy varieties, of which the double-flowered are especially worth notice, blooming as they do in the latter part of summer. R. fruticosus flore albo-pleno (Double white-flowered Bramble), and R. fruticosus flore roseo-pleno (Double red-flowered Bramble) are very pretty and showy varieties, and well worth including in any collection. There is a pretty variegated-leaved form of the common Bramble, known as R. fruticosus variegatus. R. LACINIATUS, Cut-leaved Bramble, might also be included on account of its profusion of white flowers, and neatly divided foliage. R. NUTKANUS.--North America, 1826. This has white flowers, but otherwise it resembles R. odoratus. R. ODORATUS.--Purple flowering Raspberry. North America, 1700. The sweet-scented Virginian Raspberry forms a rather dense, upright growing bush, fully 4 feet high, with large broadly five-lobed and toothed leaves, that are more or less viscid, sweet-scented, and deciduous. The leaves are placed on long, hairy, viscid foot-stalks. Flowers in terminal corymbs, large and nearly circular, purplish-red in colour, and composed of five broad, round petals. The fruit, which is rarely produced in this country, is velvety and amber-coloured. It is a very ornamental species, the ample Maple-like leaves and large flowers rendering it particularly attractive in summer. The leaves, and not the flowers as is generally supposed, are sweetly scented. R. ROSAEFOLIUS.--Rose-leaved Raspberry. Himalayas, 1811. Another half-hardy species, and only suited for planting against sunny walls. Leaves pinnate, finer than those of the Raspberry. R. r. coronarius, with semi-double white flowers, is better than the type. R. SPECTABILIS.--The Salmon Berry. North America, 1827. Grows about 6 feet high, with ternate or tri-lobate leaves that are very thickly produced. Flowers usually bright red or purplish-coloured, and placed on long pendulous footstalks. It is of very dense growth, occasioned by the number of suckers sent up from the roots. There are also some of the so-called American Brambles well worthy of attention, two of the best being Kittatiny and Lawton's:
