BRUNSVIGIA (named after the noble House of Brunswick). ORD. Amaryllideæ. Very showy greenhouse bulbous plants, from the Cape of Good Hope. Flowers red, on very long pedicels. Bulbs large. Leaves broad, horizontal; perianth with an evident longer or shorter tube, curving upwards, funnel-shaped, deeply six-parted, deciduous; segments sub-equal, many-nerved, flat, and recurved at the apex; stamens on the tube much curved upwards; scape appearing in summer without the leaves; umbels many-flowered. Propagation is effected by offsets, of which the large bulbs produce but few. These, when secured, may be removed after reaching some considerable size, carefully potted in a mixture of sandy loam and peat, with good drainage, and kept tolerably warm and close until established; water must be given but sparingly until root-action has commenced. The best place for growing the offsets into a flowering size is on a shelf near the glass, in a temperature of from 50deg. to 55deg. With an abundance of water while growing, and kept dry while semi-dormant, thus allowing them a rest, the bulbs will speedily increase in size; but it may be years before flowers are produced. Culture: This may be divided into two periods—one of growth, and one of rest. After the latter period, they should be allowed to start into fresh growth, without stimulation, and, as soon as started, liberal supplies of water should be given, and a genial temperature of from 60deg. to 65deg. maintained, to make them grow vigorously. Good-sized pots are also necessary, with a mixture of loam, peat, and sand, in equal parts. They are usually confined to the greenhouse, or warm conservatory, but are sometimes successfully grown in a south border at the base of a wall, planted out in a pit, upon which the lights may be placed in winter, and matted if necessary, as they cannot endure frost. A good depth of soil, consisting of fibrous loam, peat, and sand, in equal proportions, with good drainage, should be prepared. In all cases, the bulbs should be planted somewhat deeply. One of the most satisfactory methods of ensuring the flowering of these plants consists in subjecting the bulbs, when at rest, to a hot dry heat of 70deg. or more, which thoroughly ripens them; but, after this treatment, it will be necessary to encourage the after-growth to the fullest possible extent.

B. toxicaria (poison-bulb).* fl. pink; umbel hemispherical, many-flowered. September to October. l. many, erect, oblique, glaucous. h. 1ft. 1774. (B. R. 567.) B. coranica is a variety of this. 1815. (B. R. 139.)
FIG. 285. BRUSSELS SPROUTS.
BRUSSELS SPROUTS (Brassica oleracea bullata gemmifera). A cultivated variety of the Cabbage (Fig. 285). Leaves blistered. Stems covered with small, close heads. To secure this vegetable in its best form, it must be grown on deeply-worked and rich ground. In addition, the seeds should be obtained from a good source, as there are many spurious stocks in cultivation. Plenty of room must be allowed the plants to develop, and the tops and leaves should not be removed till after the sprouts are gathered; dead leaves, of course, excepted. It is a bad plan to plant Brussels Sprouts amongst potatoes or other crops, as they become unduly weakened, and never give such good returns as when grown by themselves.
FIG. 286. BRYONIA LACINIOSA.
Soil and Cultivation. In February, and early in March, sow thinly in a cold frame, or carefully prepare seed beds on a warm south border. As soon as the plants are large enough, prick them off into prepared soil, to grow on; about the end of April, transplant into a piece of rich ground, which has been previously prepared for them, setting in rows from 2ft. to 3ft. asunder, and 2ft. apart in the rows. The earlier the plants are put out, the better; and they should be watered-in when planted, so that they receive as little a check as possible. They must be kept clear of weeds, and earthed up as soon an they get a good size. During severe frost, some light dry litter may with advantage be thrown over them for protection; and the less they are interfered with when frozen, the better.
Sorts. The Imported is the best strain for general use; other good sorts are: Sutton's Matchless, The Aigburth, and Scrymger's Giant.
BRYA (from bryo, to sprout; the seeds germinate before falling from the tree). ORD. Leguminosæ. A small genus of stove shrubs or small trees, furnished with stipular spines, and solitary, or clustered, or pinnate leaves. The undermentioned species thrives in a rich fibry loam. Propagated by seeds, or by cuttings, placed in a hotbed.
