Blètia hyacinthìna is the only species belonging to the Green-house, once known as Cymbídium hyacinthìnum. It is herbaceous, and when it begins to grow divide the root, putting the best into five inch pots. The spike of flowers are hyacinth-like, and of a beautiful purple, flowering from April to July.
Borònia is a beautiful genus of New Holland plants, contains about nine species; most of them have been universally admired; the flowers are star-like, and rose-coloured, and some of them sweet-scented. B. pinnàta grows and flowers freely. B. serrulàta, foliage serrated and very crowded, bearing the flowers on the extremity of the shoot. B. alàta has a fine appearance, and grows handsomely. The foliage is winged and pinnate, of a hardy nature, and easy culture, flowers freely. They are in flower about April and May, and continue a considerable time; are subject to mildew if not frequently syringed; drain the pots well.
Bouvárdias, two species. B. triphylla is well known amongst us, has brilliant scarlet flowers, and when well grown, will flower beautifully from May till September. To keep the plants, they should be frequently renewed; otherwise they are liable to grow straggling, and become subject to the small white scaly insect. B. Jacquìnæ we suspect has got confounded with the former, being very little different, except the foliage, which is more pointed. They flower from the young wood, and often throw their foliage in winter.
Brachysèmas, two species, both evergreen climbers. B. latifòlium has the best foliage, and large purple leguminose flowers. B. undulàtum, flowers yellow, and more plentiful than the former, continuing in long successions. The pots require to be well drained; very few plants of either in the country.
Burchéllias, two species. B. capénsis is a beautiful dwarf evergreen shrub, with tubular scarlet flowers in large terminate clusters; when well treated, grows and flowers freely, and highly deserving of attention. B. parviflòra differs from the above in the flowers being smaller and paler, and the foliage more pointed.
Beaufórtias, only two species. B. decussàta is splendid; the flowers come out of the wood with stamens in fine parcels, colour bright scarlet, foliage decussate, oval, and many-nerved, bloom persistent, and much esteemed. B. spársa, in flower similar to the other, colour light pink, foliage scattered, both easy of culture, and flower abundantly.
Brùnias, about ten species, have heath-like foliage, very fine, generally, on close observation, found to be three cornered. The flowers are white and globular, the plants when young are very handsome; the finest are B. nodiflòra, B. lanuginósa, B. comòsa, B. abrotanoídes, and B. formòsa. They require an airy situation, and in summer to be protected from the powerful rays of the sun. Drain the pots well.
Bósea yervamóra, Golden rod tree, leaves large, alternate, ovate, acute, with purple veins and nerves, flowers brown, in axillary dense panicles, grows strong and freely.
Bæckias, above twelve species, of heath-like appearance, and except for variety, are not otherwise desirable. B. camphoràta is camphor-scented; B. pulchélla is very neat; and B. virgàta flowers freely. Pots should be well drained. The flowers of all the genus are white.
Billardiéras, about five species, are desirable as climbers, being of rapid growth, and abundant in flower. B. longiflòra, fruits freely, and has fine blue berries which look handsome. B. mutábilis is changeable from purple to scarlet. The fruit of B. scàndens is covered with down, flowers straw coloured. B. fusifórmis differs in colour from the others, the flowers being blue. They require to be well drained.
Calceolàrias, about fourteen species, besides many hybrid varieties. C. angustifòlia, and C. integrifòlia are the best of the shrubby species. C. plantagínea, C. corymbósa, C. purpùrea, and C. hopiána, and of the hybrid varieties, C. micàns and C. hybrìda are very fine; but we understand they are numerous, and some of them very splendid.
To grow any of these properly, they should be divided a few weeks after they begin to grow; put them in small pots at first, and enlarge them gradually. Where there is a hot-house, after dividing them, it will greatly promote their growth to keep them in it a few weeks near the glass, until the weather gets mild, when they may be removed to the Green-house. The flowers are principally yellow. C. Fothergíllii, purpùrea, and archnoidea are purple; the hybrids are spotted with red and brown, and some of them streaked many colours. They continue a long time in flower.
Calothámnus, four species. This genus is named in allusion to the splendid appearance of the branches, covered with scarlet flowers of curious construction, which come out of the old wood. All the species are of easy culture, and very like dwarf pines. C. quadríffida has the largest flowers; C. claváta the most abundant. They are all evergreens, and flower from April to November.
Caméllias. There are about nine species, celebrated over the known world as furnishing the domestic drug called tea, in universal use, besides many flowering trees and shrubs as universally admired. Oil may be expressed from the seeds of all the species, and used as that of hemp and poppy in cookery. C. víridis and C. bohèa are said to be the species which supply the tea. Some have asserted that there is only one shrub used, but by examination it may be easily perceived that there are leaves of various shape and texture, some of them similar to C. sasanqua. Dr. Abel gives an explicit detail of the growing and manufacturing process of tea, from which, in compliment to our fair patrons, we give a few extracts:
"The tea districts of China extend from the twenty-seventh to the thirty-first degree of north latitude. It seems to succeed best on the sides of mountains. The soils from which I collected the best specimens consisted chiefly of sand-stone, schistus, or granite. The plants are raised from seeds sown where they are to remain. Three or more are dropped into a hole four or five inches deep; these come up without further trouble, and require little culture, except that of removing weeds, till the plants are three years old. The more careful stir the soil, and some manure it, but the latter practice is seldom adopted. The third year the leaves are gathered, at three successive gatherings, in February, April and June, and so on until the bushes become stunted or slow in their growth, which generally happens in from six to ten years. They are then cut in to encourage the production of fresh roots.
"The gathering of the leaves is performed with care and selection. The leaves are plucked off one by one: at the first gathering only the unexpanded and tender are taken; at the second those that are full grown; and at the third the coarsest. The first forms what is called in Europe imperial tea; but as to the other names by which tea is known, the Chinese know nothing; and the compounds and names are supposed to be made and given by the merchants at Canton, who, from the great number of varieties brought to them, have an ample opportunity of doing so. Formerly it was thought that green tea was gathered exclusively from C. víridis; but that is now doubtful, though it is certain that there is what is called the green tea district and black tea district; and the varieties grown in the one district differ from those of the other. I was told by competent persons that either of the two plants will afford the black or green tea of the shops, but that the broad thin-leaved plant (C. víridis) is preferred for making the green tea.
"The tea leaves being gathered, are cured in houses which contain from five to twenty small furnaces, about three feet high each, having at top a large flat iron pan. There is also a long low table covered with mats, on which the leaves are laid, and rolled by workmen, who sit round it: the iron pan being heated to a certain degree by a little fire made in the furnace underneath, a few pounds of the fresh-gathered leaves are put upon the pan; the fresh and juicy leaves crack when they touch the pan, and it is the business of the operator to shift them as quickly as possible, with his bare hands, till they cannot be easily endured. At this instant he takes off the leaves with a kind of shovel resembling a fan, and pours them on the mats before the
