Statistics. The largest box trees in the neighbourhood of London are at Syon, where there are various trees from 13 ft. to 16 ft. in height. There is also one at Kew, 15 ft. high. In the Oxford Botanic Garden, there are two old box trees, one of which, in 1835, was 21 ft. high, the diameter of the trunk 7 in., and of the head 18 ft. The largest box hedge in England is at Petworth, where it is more than 12 ft. broad at the bottom, 15 ft. high, and 40 yards long: it is supposed to be upwards of two centuries old. The oldest sculpturesque topiary works in England are in the garden at Leven's Grove, in Westmoreland, laid out in the time of James II. In Scotland, at West Plean, near Stirling, there is a box tree, 10 years planted, that is 6 ft. high. In France, in the Jardin des Plantes, a box tree, upwards of 100 years planted, has attained the height of 30 ft.

Commercial Statistics. Plants of the tree box, in the London nurseries, are from 6d. to 1s. 6d. each, according to the size of the variety: at Bollwyller plants of the species are 50 cents each; and of the varieties, from 1 franc to 1 francs each at New York, plants, or the tree kind are 25 cents each; and of its varieties, 37 cents. The dwarf box is sold, in English nurseries, at 6d. per yard; at New York, at 50 cents per yard.

Disk of leaf oblong; footstalk glabrous. Anthers arrow-shaped, linear. (Willd. Sp. Pl., iv. p. 338.) A native of Minorca, Sardinia, and Corsica; and growing there, according to the Nouveau Du Hamel, to the height of 80 ft. It is also found in great abundance on all the rocky surfaces both of European and Asiatic Turkey. It was first brought to France about 1770; whence it was introduced into England in 1780. In both countries, it was at first treated as a green-house plant; but it was afterwards found quite hardy. In Paris, according to the Nouveau Du Hamel, it was found to resist the severe frosts of 1794 and

1220

1799. The Balearic box is a very handsome species, with leaves three times as large as those of B. sempervirens, and a straight smooth trunk. The leaves, when the plant is fully exposed

to the air, are of a much paler green than those of the common box; but, when they are in the shade, they are of an intensely deep green. The wood is said to be of a brighter yellow than that of the common box. It is sent to England in large quantities from Constantinople, for the use of the woodengravers; but, being of a coarser grain, it

1221

is inferior to that of the B. sempervirens. It is propagated by cuttings, which, if placed in sandy soil under glass, or in heat, generally strike root in about two months after being taken off. Cuttings will also succeed, if treated like those of the common box.

Statistics. The largest plant within 10 miles of London is at Kew, where it is 13 ft. high. At Walton on Thames, at Lady Tankerville's, it is 10 ft. high. In Sussex, at Arundel Castle, it is 17 ft. high. Price of plants, in the London nurseries, 1s. 6d. each; at New York, where it requires protection during winter, 373 cents.

App. i. Half-hardy Species of Búxus.

B. chinensis Lk. is a native of China, introduced in 1802, and growing about 3 ft. high; and B. austràlis Cun. is a native of New Holland, growing about 6 ft. high. Both require protection during winter, but would probably succeed against a conservative wall.

A true species of Búxus, Mr. Royle observes, is common in the Himalayas, found chiefly in valleys, as at Mugra, Kamaon, &c. It grows to a considerable size and thickness, and the wood appears as compact and good as that of the common box.

App. I. Half-hardy Species belonging to the Order Euphorbiaceæ.

On looking over the genera belonging to this order in the Hortus Britannicus, several ligneous species will be observed indicated as requiring the green-house; but, as very few of them are of much beauty, we consider it unnecessary to go into many details respecting them.

Plagianthus divaricatus Forst., t. 43., is a native of New Zealand, and was introduced in 1822. It is tolerably hardy; a plant having lived with us at Bayswater, with very little protection, since 1829. P. sidoides Hook. Bot. Mag., t. 3396., is a twiggy shrub, from 2 ft. to 3ft. high, probably also as hardy as the other. Both species flower in April.

Cluytia alaternördes Bot. Mag., t. 1821., has been an inhabitant of our green-houses since 1692. It is a native of the Cape of Good Hope, and would probably stand against a conservative wall.

CHAP. C.

OF THE HARDY LIGNEOUS PLANTS OF THE ORDER URTICA CEÆ.

THESE are included in five genera, which have their names and characters below.

MO`RUS Tourn. Flowers unisexual; those of the 2 sexes, in most species, upon the same plant; in M. nìgra Poir., and, according to Gronovius (Virg., 146.), in M. rùbra L., upon distinct plants: according to Kalm (Act. Suec., 1776), the sexes of M. rùbra L. are polygamous.-Male flowers disposed in a drooping, peduncled, axillary spike. Calyx of 4 equal sepals, imbricate in æstivation, expanded in flowering. Stamens 4. A rudiment of a pistil is present.- Female flowers in ovate erect spikes. Calyx of 4 leaves, in opposite pairs, the outer pair the larger, all upright and persistent, becoming pulpy and juicy. Ovary of 2 cells, one including one pendulous ovule, the other devoid of any. Stigmas 2, long. In the state of ripeness, each ovary is a fleshy and juicy utricle, and is covered by the fleshy and juicy calyx: the aggregate of the ovaries and the calyxes from a spike of flowers constitutes what is termed a mulberry. Seed pendulous

Calyx shortly tubular, then 4-parted. Stamens 4, elastic.-Female flowers in peduncled, axillary, upright globular heads. Calyx tubular, its tip with 3-4 teeth. Ovary within an integument that arises from the bottom of the calyx. Style lateral, prominent. Stigina taper. Fruit club-shaped, proceeding from the bottom of the calyx, and extended much beyond its tip; and consisting of the integument in which the ovary was enclosed, and now become very juicy; and of a 1-seeded oval utricle with a crustaceous integument, and enclosed within the juicy. integument. Species 1, native to Japan and the isles of the Pacific Ocean. A tree, with leaves large, lobed or not, and hairy. (Du Hamel, Traité des Arbres, ed. nouv.; and the Penny Cyclopædia.)

MACLU RA Nuttall. Flowers unisexual; in M. aurantiaca Nutt., and M. tinctòria D. Don, those of the two sexes upon distinct plants; if not so in the rest, then upon the same plant. What follows relates to M. aurantiaca Nutt. Male flowers in a very short almost sessile racemose panicle of 12 or more flowers. Calyx 4-parted. Stamens 4, in some instances 3. Female flowers closely aggregate upon an axis, and forming a globular head that is borne upon a short axillary peduncle. Calyx oblong, urceolar, apparently with 4 lobes at the tip: it includes the ovary, which is situated above its base, and is terminated by a style that is thread-shaped, downy, and protruded beyond the calyx to the length of nearly 1 in. The ovary becomes an achenium about in. long, half as much broad, compressed, oval, with the tip blunt and unsymmetrical from an indentation on one side in which the style had been attached. - A tree, native of North America. Spiny spines axillary. Sap white. Leaves alternate, ovate. Stipules minute, deciduous. (Nuttall; Gard. Mag., vol. xi. p. 312-316., and vol. xii. p. 210.; and observation.)

Derivation. Several derivations have been given for the word Morus: some suppose it to be taken from the Greek word morea, or moron, signifying a mulberry or blackberry; others derive it from mauros, dark; and Sir J. E. Smith suggests that it may have been taken by antiphrasis from mōros, foolish, the mulberry tree, from its slowness in putting out its leaves, being anciently considered the emblem of wisdom. The Morca, in the Levant, is said to be so called from the resemblance of the shape of that peninsula to the leaf of a mulberry.

Description, &c. Deciduous trees, natives of Europe, Asia, and America, remarkable for their large leaves, which are mostly lobed, and which, in a state of cultivation, are liable to great variation in point of magnitude, form, and texture. They are easily propagated by seeds, layers, cuttings, and truncheons; every part of the mulberry, like the olive, taking root easily, and forming a tree. All the species will serve to nourish the silkworm; but M. álba, and its varieties, are considered much the best for this purpose. In warm climates, such as Persia, the leaves of M. nìgra are sufficiently succulent for feeding the silkworm; but in colder countries they do not answer equally

well.

Smith remarks that this species is "sometimes perfectly dioecious, and very frequently partially so; the stamens being in greater perfection in most flowers of one tree, and the pistils in those of another." (Rees's Cycl., art. Morus.)

Variety.

M. n. 2 laciniàta Mill. Dicţ., No. 2., has the leaves jagged rather than cut. This alleged variety of the species may be considered as more properly a variation of the individual; since leaves jagged and lobed in a great variety of ways are frequently found on plants in one season, and only heart-shaped comparatively entire leaves the next! Description. The common mulberry is generally a low, much-branched tree, with a thick rough bark, and broad heart-shaped leaves, which are unequally serrated, and very rough. The fruit is large, of a dark purple, very wholesome, and agreeable to the palate. The mulberry tree is remarkable for the slowness of its growth; and also for being one of the last trees to develope its leaves, though it is one of the first to ripen its fruit. In Britain, the tree always assumes something of a dwarf or stunted character, spreading into very thick arms, or branches, near the ground, and forming an extremely large head. It is a tree of very great durability; the trees at Syon being said to be 300 years old, and some at Oxford and other places being supposed to be of nearly equal antiquity. It is also wonderfully tenacious of life; the roots of a black mulberry, which had lain dormant in the ground for twenty-four years, being said, after the expiration of that time, to have sent up shoots. (Ann. des Scien. Nat., tom. ix. p. 338., as quoted in Brande's Journ. for Oct. 1827.)

Geography. The common, or black, mulberry is generally supposed to be a native of Persia, where there are still masses of it found in a wild state; though the date of its introduction into Europe is unknown; and though it is occasionally found apparently wild in Italy. It is, however, so frequently confounded by the earlier writers with the white mulberry, as to render it difficult to ascertain the countries of which it is really a native.

History. The black mulberry has been known from the earliest records of antiquity. It is twice mentioned in the Bible; viz. in the Second Book of Samuel, and in the Psalms. The same difficulty, however, exists in tracing its history distinctly from that of the white mulberry, as in its geography; and it is only when spoken of as a fruit tree, or when its colour is decidedly mentioned, that we can be sure which species is meant. Ovid, however, evidently points out the black mulberry as the one introduced in the story of Pyramus and Thisbe; and Pliny seems also to allude to it, as he observes that there is no other tree that has been so neglected by the wit of man, either in grafting or giving it names; an observation which holds good to the present day respecting the black mulberry, as it has only one trifling variety, or rather variation, and no synonyme; whereas there are numerous varieties of M. álba. Pliny adds, "Of all the cultivated trees, the mulberry is the last that buds, which it never does until the cold weather is past; and it is therefore called the wisest of trees. But, when it begins to put forth buds, it despatches the business in one night, and that with so much force, that their breaking forth may be evidently heard." (Book xvi. c. 25.) The black mulberry was first brought to England in 1548; when some trees were planted at Syon, one, at least, of which (fig. 1222.) is still in existence. Others say

that the first mulberry tree planted in England was in the garden at Lambeth Palace, by Cardinal Pole, about 1555. The tree is mentioned by Tusser, and also by Gerard, who describes both the black and the white mulberry as being cultivated in his time. The royal edict of James I., about 1605, recommending the cultivation of silkworms, and offering packets of mulberry seeds to all who would sow them, no doubt rendered the tree fashionable, as

there is scarcely an old garden or gentleman's seat, throughout the country, which can be traced back to the seventeenth century, in which a mulberry tree is not to be found. It is remarkable, however, that, though these trees were expressly intended for the nourishment of silkworms, they nearly all belong to Morus nigra, as very few instances exist of old trees of Mòrus álba in England. (See Bradley's Treat. on Husb. and Gard., ed. 1726, vol. i. p. 349.) Shakspeare's mulberry is referable to this period, as it was planted in 1609 in his garden at New Place, Stratford; and it was a black mulberry, as Mr. Drake mentions a native of Stratford, who, in his youth, remembered frequently to have eaten of the fruit of this tree, some of its branches hanging over the wall which divided that garden from his father's. (Drake's Shakspeare, vol. ii. p. 584.)

Properties and Uses. The black mulberry is cultivated, Du Hamel tells us, for its fruit, which is very wholesome and palatable; and not for its leaves, which are but little esteemed for silkworms;" and which, at the beginning of autumn, often become covered with red spots. The fruit, he adds, is eaten raw, or "made into syrups, which are considered excellent for sore throats." (Nouv. Du Ham., iv. p. 91.) The wood is considered of but little value in France, except for fire-wood: it is less compact than even that of the white mulberry; and weighs only 40 lb. 7 oz. the cubic foot. Cattle eat the leaves, and all kinds of poultry are very fond of the fruit.

66

In England, the fruit is generally eaten at the dessert; and it is considered of a cooling aperient nature when ripe. It forms an agreeable sweetmeat, though it is not generally used for that purpose; and Evelyn says that, mixed with the juice of cider apples, it makes a very strong and agreeable wine. Dr. Clarke mentions that he saw some Greeks in the Crimea employed in distilling brandy from mulberries; which he describes as a weak but palatable spirit, as clear as water." (Travels, vol. i. p. 529.) A wine is also made from it in France; but it requires to be drunk immediately, as it very soon becomes acid. The root has an acrid bitter taste, and is considered excellent as a vermifuge, in doses of half a drachm in powder. (Smith in Rees's Cycl.) The tree in every part contains a portion of milky juice, which, being coagulated, is found to form a kind of coarse Indian rubber. In some parts of Spain, on Mount Etna, and in Persia, the leaves of this species are said to be preferred to those of the white mulberry for silkworms. (Hook. Bot. Comp., vol. i. p. 59.) Poetical and mythological Allusions. The mulberry was dedicated by the Greeks to Minerva, probably because it was considered as the wisest of trees; and Jupiter the Protector was called Morea. Ovid has celebrated the black mulberry tree in the story of Pyramus and Thisbe; where he tells us that its fruit was originally snow-white; but that when Pyramus, in despair at the
