B. BUXIFOLIA (_syn B. dulcis_ and _B. microphylla_).--Straits of Magellan, 1827. A neat and erect-growing shrub of somewhat stiff and upright habit, and bearing tiny yellow flowers. This is a good rockwork plant, and being of neat habit, with small purplish leaves, is well worthy of cultivation. B. CONGESTIFLORA, from Chili, is not yet well-known, but promises to become a general favourite with lovers of hardy shrubs. It is of unusual appearance for a Barberry, with long, decumbent branches, which are thickly covered with masses of orange-yellow flowers. The branch-tips, being almost leafless and smothered with flowers, impart to the plant a striking, but distinctly ornamental appearance. B. DARWINII.--Chili, 1849. This is, perhaps, the best known and most ornamental of the family. It forms a dense bush, sometimes 10 feet high, with dark glossy leaves, and dense racemes of orange-yellow flowers, produced in April and May, and often again in the autumn. B. EMPETRIFOLIA.--Straits of Magellan, 1827. This is a neat-habited and dwarf evergreen species, that even under the best cultivation rarely exceeds 2 feet in height. It is one of the hardiest species, and bears, though rather sparsely, terminal golden-yellow flowers, which are frequently produced both in spring and autumn. For its compact growth and neat foliage it is alone worthy of culture. B. FORTUNEI (_syn Mahonia Fortunei_).--China, 1846. This is rather a rare species in cultivation, with finely toothed leaves, composed of about seven leaflets, and bearing in abundance clustered racemes of individually small yellow flowers. A native of China, and requiring a warm, sunny spot to do it justice. B. GRACILIS (_syn Mahonia gracilis_).--Mexico. A pretty, half-hardy species, growing about 6 feet high, with slender branches, and shining-green leaves with bright red stalks. Flowers small, in 3-inch long racemes, deep yellow with bright red pedicels. Fruit globular, deep purple. B. ILICIFOLIA (_syn B. Neumanii_).--South America, 1791. This is another handsome evergreen species from South America, and requires protection in this country. The thick, glossy-green leaves, beset with spines, and large orange-red flowers, combine to make this species one of great interest and beauty. B. JAPONICA (_syn Mahonia japonica_).--Japan. This is not a very satisfactory shrub in these isles, although in warm seaside districts, and when planted in rich loam, on a gravelly subsoil, it forms a handsome plant with noble foliage, and deliciously fragrant yellow flowers. B. NEPALENSIS (_syn Mahonia nepalensis_).--Nepaul Barberry. This is a noble Himalayan species that one rarely sees in good condition in this country, unless when protected by glass. The long, chalky-white stems, often rising to 8 feet in height, are surmounted by dense clusters of lemon-yellow flowers. Planted outdoors, this handsome and partly evergreen Barberry must have the protection of a wall.
