Woodland Gleanings Part 14

[Ill.u.s.tration: Leaves and Globes of Flowers of _P. orientalis_.]

Of the Oriental Plane Loudon remarks, "As an ornamental tree, no one which attains so large a size has a finer appearance, standing singly, or in small groups, upon a lawn, where there is room to allow its lower branches, which stretch themselves horizontally to a considerable distance, gracefully to bend toward the ground, and turn up at their extremities. The peculiar characteristics of the tree, indeed, is the combination which it presents of majesty and gracefulness; an expression which is produced by the ma.s.sive, and yet open and varied character, of its head, the bending of its branches, and their feathering to the ground. In this respect it is greatly superior to the lime-tree, which comes nearest to it in the general character of the head; but which forms a much more compact and lumpish ma.s.s of foliage in summer, and, in winter, is so crowded with branches and spray, as to prevent, in a great measure, the sun from penetrating through them. The head of the Oriental Plane, during suns.h.i.+ne, often abounds in what painters call flickering lights; the consequence of the branches of the head separating themselves into what may be called horizontal undulating strata--or, as it is called in artistic phraseology, tufting--easily put in motion by the wind, and through openings in which the rays of the sun penetrate, and strike on the foliage below. The tree is by no means so suitable, as most others, for an extensive park, or for imitations of forest scenery; but, from its mild and gentle expression, its usefulness for shade in summer, and for admitting the sun in winter, it is peculiarly adapted for pleasure-grounds, and, where there is room, for planting near houses and buildings. For the latter purpose, it is particularly well adapted even in winter, for the colour of the bark of the trunk, which has a grayish white tint, is not unlike the colour of some kinds of freestone.

The colour of the foliage, in dry soil, is also of a dull grayish green; which, receiving the light in numerous horizontal tuftings, readily harmonizes with the colour of stone walls. It appears, also, not to be much injured by smoke, since there are trees of it of considerable size in the very heart of London."

The Oriental Plane thrives best on a light free soil, moist, but not wet at bottom; and the situation should be sheltered, but not shaded or crowded by other trees. It will scarcely grow in strong clays and on elevated exposed places; nor will it thrive in places where the lime-tree does not prosper. It may be propagated by seeds, layers, or cuttings. The general practice is to sow the seeds in autumn, covering them over as lightly as those of the birch and alder, or beating them in with the back of the spade, and not covering them at all, and protecting the beds with litter to exclude the frost. The plants will come up the following year, and will be fit, after two years' growth, to run into nursery lines; from whence they may be planted into their permanent stations in two or three years, according to the size considered necessary. The growth of this tree is very rapid, attaining in the climate of London, under favourable circ.u.mstances, the height of thirty feet in ten years, and arriving at the height of sixty or seventy feet in thirty years. The longevity of this tree was supposed, by the ancients, to be considerable; and there are few old trees in this country. One, still existing at Lee Court, in Kent, was celebrated in 1683 for its age and magnitude. Some of the largest trees in the neighbourhood of London are at Mount Grove, Hampstead, where they are between seventy and eighty feet in height; and in the grounds of Lambeth Palace, there is one ninety feet high, with a trunk of four and a half feet in diameter.

The Oriental Plane was held by the Greeks sacred to Helen; and the virgins of Sparta are represented by Theocritus as claiming homage for it, saying, "Reverence me! I am the tree of Helen." It was so admired by Xerxes, that aelian and other authors inform us, he halted his prodigious army near one of them an entire day, during its march for the invasion of Greece; and, on leaving, covered it with gold, gems, necklaces, scarfs, and bracelets, and an infinity of riches. He likewise caused its figure to be stamped on a medal of gold, which he afterwards wore continually about him.

Among many remarkable Plane-trees recorded by Pliny, he mentions one in Lycia, which had a cave or hollow in the trunk that measured eighty-one feet in circ.u.mference. In this hollow were stone seats, covered with moss; and there, during the time of his consuls.h.i.+p, Licinius Mutia.n.u.s, with eighteen of his friends, was accustomed to dine and sup! Its branches spread to such an amazing extent, that this single tree appeared like a grove; and this consul, says Pliny, chose rather to sleep in the hollow cavity of this tree, than to repose in his marble chamber, where his bed was richly wrought with curious needlework, and o'ercanopied with beaten gold. Pausanias, also, who lived about the middle of the second century, records a Plane-tree of remarkable size and beauty in Arcadia, which was then supposed to have been planted by the hands of Menelaus, the husband of Helen, which would make the age of the tree about thirteen hundred years.

At a later period magnificent examples of this umbrageous tree continued to flourish in Greece, and many of these are still existing. One of the most celebrated is at Buyukdere (or the Great Valley), about thirty miles from Constantinople, which M. de Candolle conjectured to be more than two thousand years old; when measured, in 1831, by Dr. Walsh, it was found to be one hundred and fifty-one feet in circ.u.mference at the base, and the diameter of its head covered a s.p.a.ce of one hundred and thirty feet. Some doubt, however, seems to exist as to whether it should be considered as a single tree, or as a number of individuals which have sprung from a decayed stock, and become united at the base. The hollow contained within the stem of this enormous tree, we are told, affords a magnificent tent to the Seraskier and his officers, when the Turks encamp in this valley.

Among the Turks, the Planes are preserved with a devoted and religious tenderness.

[Ill.u.s.tration: THE OCCIDENTAL OR AMERICAN PLANE.]

THE OCCIDENTAL OR AMERICAN PLANE.

[_Plata.n.u.s occidentalis._ Nat. Ord.--_Platanaceae_; Linn.--_Monoec.

Polya._]

The American or Western Plane is found over an immense area in North America, comprising the Atlantic and western states, and extending beyond the Mississippi. In the Atlantic states, this tree is commonly known by the name of b.u.t.ton-wood; and sometimes, in Virginia, by that of water-beech, from its preferring moist localities, "where the soil is loose, deep, and fertile." On the banks of the Ohio, and in the states of Kentucky and Tennessee, it is commonly called sycamore, and sometimes plane-tree. The b.u.t.ton-tree is, however, the name by which this tree is most generally known in America.

The Western Plane was first introduced into England about 1630, and was afterwards so generally planted, in consequence of its easy propagation by cuttings and rapid growth, that it soon became more common than _P.

orientalis_. This tree is now, however, rare in this country, from the greater number having been killed by a severe frost in May 1809, and by the severe winter of 1813-4.

The American Plane, in magnitude and general appearance, closely resembles the oriental plane. The one species, however, can always be distinguished from the other by the following characters:--In the Oriental Plane, the leaves are smaller and much more deeply lobed than in the Western tree, and the petioles of the leaves, which in the Oriental species are green, in the American tree are purplish-red; the fruit, or ball-shaped catkins, also, of the Western Plane, are considerably larger, and not so rough externally as those of the other.

The bark is said to scale off in larger pieces, and the wood to be more curiously veined. In all other respects, the descriptive particulars of both trees are the same. According to Michang, the Western Plane is "the loftiest and largest tree of the United States." In 1802, he saw one growing on the banks of the Ohio, whose girth at four feet from the ground, was 47 feet, or nearly 16 feet in diameter. This tree, which showed no symptoms of decay, but on the contrary exhibited a rich foliage and vigorous vegetation, began to ramify at about 20 feet from the ground, a stem of no mean length, but short in comparison to many large trees of this species that he met with, whose boles towered to a height of 60 or 70 feet without a single branch. Even in England, specimens of the Western Plane, of no great age, are to be met with 100 feet in height. The rate of growth of _P. occidentalis_, when placed near water, is so rapid, that in ten years it will attain the height of forty feet; and a tree in the Palace Garden at Lambeth, near a pond, in twenty years had attained the height of eighty feet, with a trunk eight feet in circ.u.mference at three feet from the ground, and the diameter of the head forty-eight feet. This was in 1817.--(See Neill's _Hort. Tour_, p. 9.)

As a picturesque tree, Gilpin places the Occidental Plane after the oak, the ash, the elm, the beech, and the hornbeam, which he considers as deciduous trees of the first rank; saying of both species of Plata.n.u.s, that, though neither so beautiful nor so characteristic as the first-named trees, they are yet worth the notice of the eye of the admirer of the picturesque.

[Ill.u.s.tration: Leaves and Flowers of _P. occidentalis_.]

"The Occidental Plane has a very picturesque stem. It is smooth, and of a light ash colour, and has the property of throwing off its bark in scales; thus naturally cleansing itself, at least its larger boughs, from moss, and other parasitical enc.u.mbrances." This would be no recommendation of it in a picturesque light, if the removal of these enc.u.mbrances did not subst.i.tute as great a beauty in their room. These scales are very irregular, falling off sometimes in one part, and sometimes in another; and, as the under bark is, immediately after its excoriation, of a lighter hue than the upper, it offers to the pencil those smart touches which have so much effect in painting. These flakes, however, would be more beautiful if they fell off in a circular form, instead of a perpendicular one: they would correspond and unite better with the round form of the bole. "No tree forms a more pleasing shade than the Occidental Plane. It is full-leafed, and its leaf is large, smooth, of a fine texture, and seldom injured by insects. Its lower branches shooting horizontally, soon take a direction to the ground, and the spray seems more sedulous than that of any tree we have, by twisting about in various forms, to fill up every little vacuity with shade. At the same time, it must be owned that the twisting of its branches is a disadvantage to this tree, as it is to the beech. When it is stripped of its leaves, and reduced to a skeleton, it has not the natural appearance which the spray of the oak, and that of many other trees, discovers in winter; nor, indeed, does its foliage, from the largeness of the leaf and the mode of its growth, make the most picturesque appearance in summer. One of the finest Occidental Planes I am acquainted with stands in my own garden at Vicar's Hill; where its boughs, feathering to the ground, form a canopy of above fifty feet in diameter."

The Occidental Plane is propagated by cuttings, which will hardly fail to succeed if they are taken from strong young wood, and are planted early in the autumn in a moist good mould.

[Ill.u.s.tration: THE POPLAR TREE.]

THE POPLAR TREE.

[_Populus._[Q] Nat. Ord.--_Amentiferae_; Linn.--_Dioec. Octa._]

[Q] _Generic characters._ Flowers of both kinds in cylindrical catkins.

_Barren_ flowers consisting of numerous stamens, arising out of a small, oblique, cup-like perianth. _Fertile_ flowers consisting of 4 or 8 stigmas, arising out of a cup-like perianth; _fruit_ a follicle, 2-valved, almost 2-celled by the rolling in of the margins of the valves.

The Poplars are deciduous trees, mostly growing to a large size; natives of Europe, North America, some parts of Asia, and the north of Africa.

They are all of rapid growth, some of them extremely so; and they are all remarkable for a tremulous motion in their leaves, when agitated by the least breath of wind. The species delight in a rich, moist soil, in the neighbourhood of running water, but they do not thrive in marshes or soils saturated with stagnant moisture. Their wood is light, of a white or pale yellowish colour, very durable when kept dry, not liable to warp or twist when sawn up, and yields, from its elasticity, without splitting or cracking when struck with violence; that of some species is also very slow in taking fire, and burns, when ignited, in a smouldering manner, without flame, on which account it is valuable, and extensively used for the flooring of manufactories and other buildings. Of the fifteen species of Poplar described in Loudon's _Arboretum_, three are believed to be natives of this country--_P. canescens_, _P. tremula_, and _P. nigra_.

_P. canescens_, the Gray or Common White Poplar, and its different varieties, form trees of from eighty to one hundred feet high and upwards, with silvery smooth bark, upright and compact branches, and a clear trunk, to a considerable height, and a spreading head, usually in full-grown trees, but thinly clothed with foliage. The leaves are roundish, deeply waved, lobed, and toothed; downy beneath, chiefly grayish; leaves of young shoots cordate-ovate, undivided fertile catkins cylindrical. Stigmas 8.

[Ill.u.s.tration: Leaves, Flowers, and Catkins of _P. canescens_.]

The White Poplar is commonly propagated by layers, which ought to be transplanted into nursery lines for at least one year before removal to their final situation. The tree is admirably adapted for thickening or filling up blanks in woods and plantations; and, for this purpose, truncheons may be planted from three to four inches in diameter, and from ten to twelve feet high. These truncheons have the great advantage of not being overshadowed by the adjoining trees, which is almost always the case when young plants are used for filling up vacancies among old trees. In a moderately good and moist soil, the White Poplar will attain in ten years, the height of thirty feet or upwards, with a trunk from six to nine inches in diameter.

As an ornamental tree, the White Poplar is not unworthy of a place in extensive parks and grounds, particularly when planted in lone situations, or near to water; it ought, however, to be grouped and ma.s.sed with trees of equally rapid growth, else it soon becomes disproportionate, and out of keeping with those whose progress is comparatively slow. It is well adapted in our climate for a wayside tree, as it has no side branches to prevent the admission of light and free circulation of air; and also to form avenues, when an effect is wished to be produced in the shortest possible time.

The Aspen or Trembling Poplar, _P. tremula_, is inferior to few of its tribe, presenting the appearance of a tall, and, in proportion to its height, rather a slender tree, with a clean straight trunk; the head ample, and formed of horizontal growing branches, not crowded together, which a.s.sume, towards the extremities, a drooping or pendulous direction. The leaves are nearly orbicular, sinuate, or toothed, smooth on both sides; foot-stalks compressed; young branches hairy; stigmas 4, crested and eared at the base. The foliage is of a fine rich green; and the upper surface of the leaves being somewhat darker than the under, a sparkling and peculiar effect is produced by the almost constant tremulous motion with which they are affected by the slightest breath of air, and which is produced by the peculiar form of the foot-stalks, which in this species is flattened, or vertically compressed in relation to the plane of the leaf, causing a quivering or double lateral motion, instead of the usual waving motion, where the foot-stalk is round, or else compressed horizontally.

The Black Poplar, _P. nigra_, is a tree of the largest size, with an ample head, composed of numerous branches and terminal shoots. The bark is ash-coloured, and becomes rough and deeply furrowed with age. The catkins are bipart.i.te, cylindrical; the barren appear in March or April, long before the expansion, of the leaves, and, being large and of a deep red colour, produce a rich effect at that early period of the year. The capsules or seed-vessels of the fertile catkin are round, and contain a pure white cottony down, in which the seeds are enveloped. The leaves appear about the middle of May, and, when they first expand, their colour is a mixture of red and yellow; afterwards they are of a pale light green, with yellowish foot-stalks; remarkably triangular, ac.u.minate, serrate, smooth on both sides; stigmas 4.

There is a Black Poplar at Alloa House, in Clackmannans.h.i.+re, which, in 1782, at the height of between three and four feet from the ground, measured thirteen feet and a half in circ.u.mference. There is also a very graceful and beautiful tree of the same species at Bury St. Edmunds, ninety feet in height, and which measures, at the distance of three feet from the ground, fifteen feet in girth. The trunk rises forty-five feet before it divides, when it throws out a vast profusion of branches.

The Poplar was dedicated by the Romans to Hercules, in honour of his having destroyed the monster Cacus in a cavern near to the Aventine Mount, where the Poplar formerly flourished in abundance. In Pitt's translation of Virgil, the following reference is made to the rite of crowning with the Poplar:--

From that blest hour th' Arcadian tribe bestowed Those solemn honours on their guardian G.o.d.

Pot.i.tius first, his grat.i.tude to prove, Adored Alcides[2] in the shady grove; And with the old Pinarian sacred line These altars raised, and paid the rites divine,-- Rites, which our sons for ever shall maintain; And ever sacred shall the grove remain.

Come, then, with us to great Alcides pray, And crown your heads, and solemnize the day.

Invoke our common G.o.d with hymns divine, And from the goblet pour the generous wine.

He said, and with the Poplar's sacred boughs, Like great Alcides, binds his h.o.a.ry brows.

[2] The Greek name of Hercules.
