PHOTINIA JAPONICA (_syn Eriobotrya japonica_).--Loquat, Japan Medlar, or Japan Quince. Japan, 1787. This is chiefly remarkable for its handsome foliage, the leaves being oblong of shape and downy on the under sides. The white flowers are of no great beauty, but being produced at the beginning of winter, and when flowers are scarce, are all the more welcome. It requires protection in all but the warmer parts of these islands. P. ARBUTIFOLIA (_syns Crataegus arbutifolia_ and _Mespilus arbutifolia_).--Arbutus-leaved Photinia, or Californian May-bush. California, 1796. This is a very distinct shrub, with leaves resembling those of the Strawberry Tree (Arbutus), the flowers in an elongated panicle, and bright red bark on the young wood. P. BENTHAMIANA is only worthy of culture for its neat habit and freedom of growth when suitably placed. P. SERRULATA (_syn Crataegus glabra_).--Chinese Hawthorn. Japan and China, 1804. This has Laurel-like leaves, 4 inches or 5 inches long, and, especially when young, of a beautiful rosy-chocolate colour, and clustered at the branch-tips. Flowers small, white, and produced in flat corymbs. An invaluable seaside shrub. They all grow well either in light, rich loam, or in sandy, peaty earth, and are usually propagated by grafting. PHYLODOCE. PHYLODOCE TAXIFOLIA (_syns P. caerulea_ and _Menziesia caerulea_).--An almost extinct native species, having crowded linear leaves, and lilac-blue flowers. It is only of value for rock gardening. PIERIS. PIERIS FLORIBUNDA (_syns Andromeda floribunda_ and _Leucothoe floribunda_).--United States, 1812. Few perfectly hardy shrubs are more beautiful than this, with its pure white Lily-of-the-Valley like flowers, borne in dense racemes and small, neat, dark green leaves. To cultivate this handsome shrub in a satisfactory way, fairly rich loam or peat, and a situation sheltered from cold and cutting winds, are necessities. P. JAPONICA (_syn Andromeda japonica_).--Japan, 1882. A hardy, well-known shrub, that was first brought specially under notice in "The Garden," and of which a coloured plate and description were given. It is thickly furnished with neat and small deep-green, leathery leaves, and pretty, waxy white flowers, pendulous at the branch tips. Planted in free, sandy peat, it thrives vigorously, and soon forms a neat specimen of nearly a yard in height. It is a very desirable hardy species, and one that can be confidently recommended for ornamental planting. There is a variegated variety, P. japonica elegantissima, with leaves clearly edged with creamy-white, and flushed with pink. Amongst variegated, small-growing shrubs it is a gem. P. MARIANA (_syn Andromeda Mariana ovalis_).--North America, 1736. A neat shrub of about 3 feet in height, with oval leaves, and pretty white flowers in pendent clusters.
