BILLARDIERA LONGIFLORA.--Blue Apple Berry. Van Diemen's Land, 1810. If only for its rich, blue berries, as large as those of a cherry, this otherwise elegant climbing shrub is well worthy of a far greater share of attention than it has yet received, for it must be admitted that it is far from common. The greenish bell-shaped blossoms produced in May are, perhaps, not very attractive, but this is more than compensated for by the highly ornamental fruit, which renders the plant an object of great beauty about mid-September.
