The Snowberry (_Symphoria racemosa_) bears considerable resemblance to the upright Honeysuckles. The flowers are funnel-shaped, and four or five lobed. The berry has four cells, but two of the cells are empty, and the others have only one seed in each. The leaves are oval, quite entire, and not connate. _Leycesteria_ is a very handsome shrub, with white flowers, and very large and showy purple and reddish bracts. The berries are of a very dark purple, and they are nearly as large as a gooseberry. _L. formosa_ is a native of Nepaul, but it appears tolerably hardy in British gardens, and it stands the sea-breeze without injury. _Linnæa borealis_ is a little for insignificant trailing plant, which is included in this order, and which is only worth mentioning on account of its being named in honour of Linnæus. It is a half-shrubby evergreen, with small bell-shaped flesh-coloured flowers, which are said to be fragrant at night. ORDER CI.—LORANTHEÆ. Four genera are included in this order, all remarkable in different ways. The first of these is the common Mistletoe (_Viscum album_), a most remarkable parasite, a native of Britain, and generally found on old apple-trees; and the second is _Loranthus europæus_, a native of Germany, closely resembling the Mistletoe, but found generally on the oak, where the true Mistletoe rarely grows. This plant is said to have been introduced in 1824, but it is not now in the country. There are other species of the genera, one a native of New Holland. _Nuytsia floribunda_, also a native of New Holland, a very curious plant, is also included in this order. It is a shrub about three feet high, so covered with orange-coloured blossoms that the colonists call it the Fire-tree. When the seed of this plant germinates, it is said to have three cotyledons. The last plant generally included in this order is _Aucuba japonica_, though it is probable this plant belongs to Cornaceæ. Of this species we have probably only a variety, from the variegation of the leaves; and it has never produced seeds, as only the female plant has been introduced. ORDER CII.—CHLORANTHEÆ. Inconspicuous plants with greenish flowers, which require a hothouse in Britain. ORDER CIII.—RUBIACEÆ. (SEE CHAP. V. P. 85.) This order is divided into thirteen sections, most of which have been already described. In all the species the tube of the calyx adheres to the ovary, which is crowned with a fleshy cup, from which arises the single style; and the petals are united at the base, and attached to the upper part of the tube of the calyx. ORDER CIV.—OPERCULARIEÆ. Exotic weeds, formerly included in Rubiaceæ. ORDER CV.—VALERIANEÆ.—THE VALERIAN TRIBE.
