Wherever in the tropical regions periodical rains saturate12 the earth, vegetable life expands in a wonderful variety of forms. In the higher latitudes13 of the frozen north, a rapidly evanescent summer produces but few and rare flowers in sheltered situations, soon again to disappear under the winter’s snow; in the temperate14 zones, the number, beauty, and variety of plants increases with the warmth of a genial15 sky; but it is only where the vertical16 rays of an equatorial sun awaken17 and foster life on humid grounds that ever-youthful Flora18 appears in the full exuberance19 of her creative power. It is only there we find the majestic21 palms, the elegant121 mimosas, the large-leafed bananas, and so many other beautiful forms of vegetation alien to our cold and variable clime. While our trees are but sparingly clad with scanty22 lichens23 and mosses24, they are there covered with stately bromelias and wondrous25 orchids26. Sweet-smelling vanillas27 and passifloras wind round the giants of the forest, and large flowers break forth28 from their rough bark, or even from their very roots.
The number of known plants is estimated at about 200,000, and the greater part of this vast multitude of species belongs to the torrid zone. But if we consider how very imperfectly these sunny regions have as yet been explored—that in South America enormous forest lands and river basins have never yet been visited by a naturalist—that the vegetation of the greater part of Central Africa is still completely hidden in mystery—that no botanist30 has ever yet penetrated32 into the interior of Madagascar, Borneo, New Guinea, South-Western China, and Ultra-Gangetic India—and that, moreover, many of the countries visited by travellers have been but very superficially examined—we may well doubt whether even one fourth part of the tropical plants is actually known to science.
After these general remarks on the variety and exuberance of tropical vegetation, I shall now briefly33 notice those plants which, by their enormous size, their singularity of form, or their frequency in the landscape, chiefly characterise the various regions of the torrid zone.
The African Baobab, or monkey-bread tree (Adansonia digitata), may justly be called the elephant of the vegetable world. Near the village Gumer, in Fassokl, Russegger saw a baobab thirty feet in diameter and ninety-five in circumference35; the horizontally outstretched branches were so large that the negroes could comfortably sleep upon them. The Venetian traveller Cadamosto (1454) found, near the mouths of the Senegal, baobabs measuring more than a hundred feet in circumference. As these vegetable giants are generally hollow, like our ancient willows36, they are frequently made use of as dwellings37 or stables; and Dr. Livingstone mentions one in which twenty or thirty men could lie down and sleep, as in a hut. In the village of Grand Galarques, in Senegambia, the negroes have decorated the entrance into the cavity of a monstrous38 baobab with rude sculptures cut into the living122 wood, and make use of the interior as a kind of assembly room, where they meet to deliberate on the interests of their small community, ‘reminding one,’ says Humboldt, ‘of the celebrated39 plantain in Lycia, in whose hollow trunk the Roman consul40, Lucinius Mutianus, once dined with a party of twenty-one.’ As the baobab begins to decay in the part where the trunk divides into the larger branches, and the process of destruction thence continues downwards41, the hollow space fills, during the rainy season, with water, which keeps a long time, from its being protected against the rays of the sun. The baobab thus forms a vegetable cistern, whose water the neighbouring villagers sell to travellers. In Kordofan the Arabs climb upon the tree, fill the water in leathern buckets, and let it down from above; but the people in Congo more ingeniously bore a hole in the trunk, which they stop, after having tapped as much as they require.11
The height of the baobab does not correspond to its amazing bulk, as it seldom exceeds sixty feet. As it is of very rapid growth, it acquires a diameter of three or four feet and its full altitude in about thirty years, and then continues to grow in circumference. The larger beam-like branches, almost as thick at their extremity42 as at their origin, are abruptly43 rounded, and then send forth smaller branches, with large, light green, palmated leaves. The bark is smooth and greyish. The oval fruits, which are of the size of large cucumbers, and brownish-yellow when ripe, hang from long twisted spongy stalks, and contain a white farinaceous substance, of an agreeable acidulated taste, enveloping44 the dark brown seeds. They are a favourite food of the monkeys, whence the tree has derived45 one of its names.
From the depth of the incrustations formed on the marks which the Portuguese46 navigators of the fifteenth century used to cut in the large baobabs which they found growing on the African coast, and by comparing the relative dimensions of several trunks of a known age, Adanson concluded that a baobab of thirty feet in diameter must have lived at least 5,000 years; but a more careful investigation47 of the rapid growth of the spongy wood has reduced the age of the giant tree to more moderate limits, and proved that, even in123 comparative youth, it attains49 the hoary50 aspect of extreme senility.
The baobab, which belongs to the same family as the mallow or the hollyhock, and is, like them, emollient51 and mucilaginous in all its parts, ranges over a wide extent of Africa, particularly in the parts where the summer rains fall in abundance, as in Senegambia, in Soudan, and in Nubia. Dr. Livingstone admired its colossal proportions on the banks of the Zouga and the Zambesi. It forms a conspicuous52 feature in the landscape at Manaar in Ceylon, where it has most likely been introduced by early mariners53, perhaps even by the Phœnicians, as the prodigious55 dimensions of the trees are altogether inconsistent with the popular conjecture56 of a Portuguese origin.
DRAGON-TREE OF OROTAVA.
Another tree very characteristic of Africa, and frequently seen along with the baobab, is the large arborescent Euphorbia (E. arborescens), surmounted57 at the top with stiff leaves, branching out like the arms of a huge candelabra. It adds greatly to the strange wildness of the landscape, and seems quite in character with the aspect of the unwieldy rhinoceros58 and the long-necked giraffe.
Dracænas, or dragon-trees, are found growing on the west coast of Africa and in the Cape34 Colony, in Bourbon and in China; but it is only in the Canary Islands, in Madeira, and Porto Santo, that they attain48 such gigantic dimensions as to entitle them to rank among the vegetable wonders of the world.
Unfortunately, the venerable dragon-tree of Orotava, in Teneriffe, which was already reverenced59 for its age by the extirpated60 nation of the Guanches, and which the adventurous61 Bethencourts, the conquerors62 of the Canaries, found hardly less colossal and cavernous in 1402 than Humboldt, who visited it in 1799, was destroyed by a storm in 1871. Above the roots the illustrious traveller measured a circumference124 of forty-five feet; and according to Sir George Staunton, the trunk had still a diameter of four yards, at an elevation63 of ten feet above the ground. The whole height of the tree was not much above sixty-five feet. The trunk divided in numerous upright branches, terminating in tufts of evergreen64 leaves, resembling those of the pine-apple.
Next to the baobab and the dracæna, the Sycamore (Ficus Sycomorus) holds a conspicuous rank among the giant trees of Africa. It attains a height of only forty or fifty feet, but in the course of many centuries its trunk swells66 to a colossal size, and its vast crown covers a large space of ground with an impenetrable shade. Its leaves are about four inches long and as many broad, and its figs67 have an excellent flavour. In Egypt it is almost the only grove10-forming tree; and most of the mummy coffins68 are made of its incorruptible wood.
SYCAMORE.
No baobab rears its monstrous trunk on the banks of the Ganges; no dragon-tree of patriarchal age here reminds the wanderer of centuries long past; but the beautiful and stately Banyan (Ficus indica) gives him but little reason to regret their absence. Each tree is in itself a grove, and some of them are of an astonishing size, as they are continually increasing, and,125 contrary to most other animal and vegetable productions, seem to be exempted70 from decay; for every branch from the main body throws out its own roots, at first in small tender fibres, several yards from the ground, which continually grow thicker, until, by a gradual descent, they reach its surface, where, striking in, they increase to a large trunk and become a parent-tree, throwing out new branches from the top. These in time suspend their roots, and, receiving nourishment71 from the earth, swell65 into trunks and send forth other branches, thus continuing in a state of progression so long as the first parent of them all supplies her sustenance72.
BANYAN.
The bended twigs73 take root, and daughters grow About the mother-tree; a pillar’d shade High overarch’d, and echoing walks between. There oft the Indian herdsman, shunning75 heat, Shelters in cool, and tends his pasturing herds74 At loopholes cut through thickest shade.
These beautiful lines of Milton are by no means overdrawn76; as a banyan tree, with many trunks, forms the most beautiful walks and cool recesses77 that can be imagined. The leaves are large, soft, and of a lively green; the fruit is a small fig (when ripe of a bright scarlet), affording sustenance to monkeys, squirrels, peacocks, and birds of various kinds, which dwell among the branches.
The Hindoos are peculiarly fond of this tree; they consider its long duration, its outstretching arms and overshadowing beneficence, as emblems of the Deity79; they plant it near their dewals or temples; and in those villages where there is no structure for public worship they place an image under a banyan, and there perform a morning and evening sacrifice.
126 Many of these beautiful trees have acquired an historic celebrity80; and the famous Cubbeer-burr, on the banks of the Nerbuddah, thus called by the Hindoos in memory of a favourite saint, is supposed to be the same as that described by Nearchus, the Admiral of Alexander the Great, as being able to shelter an army under its far-spreading shade. ‘High floods have at various times swept away a considerable part of this extraordinary tree, but what still remains81 is near 2,000 feet in circumference, measured round the principal stems; the overhanging branches not yet struck down cover a much larger space; and under it grow a number of custard-apple and other fruit trees. The large trunks of this single colossus amount to a greater number than the days of the year, and the smaller ones exceed 3,000, each constantly sending forth branches and hanging roots to form other trunks and become the parents of a future progeny82.
‘About a century ago a neighbouring rajah, who was extremely fond of field diversions, used to encamp under it in a magnificent style, having a saloon, drawing-room, dining-room, bed-chamber, bath, kitchen, and every other accommodation, all in separate tents; yet the noble tree not only covered the whole, together with his carriages, horses, camels, guards, and attendants, but also afforded with its spreading branches shady spots for the tents of his friends, with their servants and cattle. And in the march of an army it has been known to shelter 7,000 men.’12 Such is the banyan—more wonderful than all the temples and palaces which the pride of the Moguls has ever reared!
The nearly related Pippul of India, or Bo-tree (Ficus religiosa), which differs from the banyan (F. indica) by sending down no roots from its branches, is reverenced by the Buddhists83 as the sacred plant, under whose shade Gautma, the founder84 of their religion, reclined when he underwent his divine transfiguration. Its heart-shaped leaves, which, like those of the aspen, appear in the profoundest calm to be ever in motion, are supposed to tremble in recollection of that mysterious scene.
The sacred Pippul at Anarajapoora, the fallen capital of the ancient kings of Ceylon, is probably the oldest historical tree in the world; as it was planted 288 years before Christ, and127 hence is now 2,150 years old. The enormous age of the baobabs of Senegal, and of the wondrous Wellingtonias of California, can only be conjectured85; but the antiquity86 of the Bo-tree is matter of record, as its preservation87 has been an object of solicitude88 to successive dynasties; and the story of its fortunes has been preserved in a series of continuous chronicles amongst the most authentic89 that have been handed down by mankind.
THE SACRED BO-TREE OF ANARAJAPOORA.
‘Compared with it, the Oak of Ellerslie is but a sapling, and the Conqueror’s Oak in Windsor Forest barely numbers half its years. The yew90 trees of Fountains Abbey are believed to have flourished there 1,200 years ago; the olives in the Garden128 of Gethsemane were full-grown when the Saracens were expelled from Jerusalem, and the cypress91 of Somma in Lombardy is said to have been a tree in the time of Julius Cæsar. Yet the Bo-tree is older than the oldest of these by a century, and would almost seem to verify the prophecy pronounced when it was planted, that it would ‘flourish and be green for ever.’13
Although far inferior to these wonders of the vegetable world in amplitude92 of growth, yet the Teak tree, or Indian oak (Tectona grandis), far surpasses them in value, as the ship-worm in the water, and the termite93 on land, equally refrain from attacking its close-grained strongly scented94 wood; and no timber equals it for ship-building purposes.
It grows wild over a great part of British India; in the mountainous districts along the Malabar coast, in Guzerat, the valley of the Nerbuddah, in Tenasserim and Pegu. Unlike the oak and fir forests of Europe, where large spaces of ground are covered by a single species, the teak forests of India are composed of a great variety of trees, among which the teak itself does not even predominate. After a long neglect, which, in some parts, had almost caused its total extirpation96, Government has at length taken steps for its more effectual protection, and appointed experienced foresters to watch over this invaluable97 tree. Since 1843, millions of young plants have been raised from seeds, but unfortunately the teak is of as slow growth as our oak, and many years will still be necessary to repair the ruinous improvidence98 of the past.
On turning our attention to America we find that Nature, delighting in infinite varieties of development, and disdaining99 a servile copy of what she had elsewhere formed, covers the earth with new and no less remarkable100 forms of vegetation. Thus, while in Africa the baobab attracts the traveller’s attention by its colossal size and peculiarity102 of growth, the gigantic Ceiba (Bombax Ceiba), belonging to the same family of plants, raises his astonishment103 in the forests of Yucatan. Like the baobab, this noble tree rises only to a moderate height of sixty feet, but its trunk swells to such dimensions that fifteen men are hardly able to span it, while a thousand may easily screen themselves under its canopy104 from the scorching105 sun. The leaves fall off129 in January; and then at the end of every branch bunches of large, glossy106, purple-red flowers make their appearance, affording, as one may well imagine, a magnificent sight.
In British Honduras the Mahogany-tree (Swietenia Mahagoni) is found scattered107 in the forests, attracting the woodman’s attention from a distance by its light-coloured foliage108, and its magnificent growth. Such are its dimensions, and such is the value of peculiarly fine specimens109, that in October 1823 a tree was felled which weighed more than seven tons, and at Liverpool was sold for 525l. The expense of sawing amounted to 750l. more: so that the wood of this single tree, before passing into the hands of the cabinet-maker, was worth as much as a moderately sized farm.
‘Heedless and bankrupt in all curiosity must he be,’ says Waterton,14 ‘who can journey through the forests of Guiana without stopping to take a view of the towering Mora (Mora excelsa). Its topmast branch, when naked with age, or dried by accident, is the favourite resort of the toucan110. Many a time has this singular bird felt the shot faintly strike him from the gun of the fowler beneath, and owed his life to the distance betwixt them. The wild fig tree, as large as a common English apple-tree, often rears itself from one of the thick branches at the top of the mora; and when its fruit is ripe, to it the birds resort for nourishment. It was to an indigested seed passing through the body of this bird, which had perched on the mora, that the fig tree first owed its elevated station there. The sap of the mora raised it into full bearing; but now, in its turn, it is doomed111 to contribute a portion of its own sap and juices towards the growth of different species of vines, the seeds of which also the birds deposited on its branches. These soon vegetate112 and bear fruit in great quantities; so, what with their usurpation113 of the resources of the fig-tree, and the fig-tree of the mora, the mora, unable to support a charge which Nature never intended it should, languishes114 and dies under its burden; and then the fig-tree and its usurping115 progeny of vines, receiving no more succour from their late foster-parent, droop116 and perish in their turn.’
Our stateliest oaks would look like pygmies near this chieftain of the forests,’ who raises his dark green cupola over all130 the neighbouring trees, and deceives the traveller, who fancies that a verdant117 hill is rising before him. Its wood is much firmer than that of the fir, and is, or will be, of great importance to the ship-builder. On the Upper Barima alone, a river of Guiana hardly even known by name in Europe, Schomburgk found the giant tree growing in such profusion118 that it could easily afford sufficient timber for the proudest fleet that ever rode the ocean.
The graceful119 tapering120 form of the Gramineæ, or grasses, belongs to every zone; but it is only in the warmer regions of the globe that we find the colossal Bambusaceæ, rivalling in grandeur121 the loftiest trees of the primeval forest.
In New Grenada and Quito the Guadua, one of these giant grasses, ranks next to the sugar-cane122 and maize123 as the plant most indispensable to man. It forms dense124 jungles, not only in the lower regions of the country, but in the valleys of the Andes, 5,000 feet above the level of the sea. The culms attain a thickness of six inches, the single joints125 are twenty inches long, and the leaves are of indescribable beauty. A whole hut can be built and thatched with the guadua, while the single joints are extensively used as water-vessels128 and drinking-cups.
India, South China, and the Eastern Archipelago are the seats of the real bamboos, which grow in a variety of genera and species, as well on the banks of lakes and rivers in low marshy129 grounds, as in the more elevated mountainous regions. They chiefly form the impenetrable jungles, the seat of the tiger and the python. Sometimes a hundred culms spring from a single root, not seldom as thick as a man, and towering to a height of eighty or a hundred feet. Fancy the grace of our meadow grasses, united with the lordly growth of the Italian poplar, and you will have a faint idea of the beauty of a clump130 of bamboos.
The variety of purposes to which these colossal reeds can be applied131 almost rivals the multifarious uses of the cocoa-nut palm itself. Splitting the culm in its whole length into very thin pieces, the industrious132 Chinese then twist them together into strong ropes, for tracking their vessels on their numerous rivers and canals. The sails of their junks, as well as their cables and rigging, are made of bamboo; and in the southern province of Sechuen, not only nearly every house is built solely131 of this strong cane, but almost every article of furniture which it contains—mats, screens, chairs, tables, bedsteads, bedding—is of the same material. From the young shoots they also fabricate their fine writing-paper, which is so superior to the produce of our own manufactories. Although the bamboo grows spontaneously and most profusely134 in nearly all the southern portion of their vast empire, they do not entirely135 rely on the beneficence of Nature, but cultivate it with the greatest care. They have treatises136 devoted137 solely133 to this subject, laying down rules derived from experience, and showing the proper soils, the best kinds of water, and the seasons for planting and transplanting the bamboos, whose use is scarcely less extensive throughout the whole East Indian world.
At one season of the year the bamboos are easily destroyed by fire; and as the great stem-joints burst from the expansion of the air confined within, the report almost rivals the roar of cannon138. In Sikkim firing the jungle is a frequent practice, and Dr. Hooker, who often witnessed the spectacle, describes the effect by night as exceedingly grand. ‘Heavy clouds canopy the mountains above, and, stretching across the valleys, shut out the sky; the air is a dead calm, as usual in the deep gorges139; and the fires, invisible by day, are seen raging all around, appearing to an inexperienced eye in all but dangerous proximity140. The voices of birds and insects being hushed, nothing is audible but the harsh roar of the rivers, and occasionally rising far above it, that of the forest fires. At night we were literally141 surrounded by them; some smouldering like the shale-heaps at a colliery, others fitfully bursting forth, whilst others again stalked along with a steadily143 increasing and enlarging flame, shooting out great tongues of fire, which spared nothing as they advanced with irresistible144 might. At Darjiling the blaze is visible, and the deadened reports of the bamboos bursting is heard throughout the night; but in the valley, and within a mile of the scene of destruction, the effect is the most grand, being heightened by the glare reflected from the masses of mist which hover145 above.’15
The aloes form the strongest contrast to the airy lightness of the grasses, by the stately repose146 and strength of their thick,132 fleshy, and inflexible147 leaves. They generally stand solitary148 in the parched149 plains, and impart a peculiarly austere150 or melancholy151 character to the landscape. The real aloes are chiefly African, but the American yuccas and agaves have a similar physiognomical character. The Agave americana, the usual ornament152 of our hot-houses, bears on a short and massive stem a tuft of fleshy leaves, sometimes no less than ten feet long, fifteen inches wide, and eight inches thick! After many years a flower-stalk twenty feet high shoots forth in a few weeks from the heart of the plant, expanding like a rich candelabrum, and clustered with several thousands of greenish-yellow aromatic153 flowers. But a rapid decline succeeds this brilliant efflorescence, for it is soon followed by the death of the exhausted154 plant.
In Mexico, where the agave is indigenous155, and whence it has found its way to Spain and Italy, it is reckoned one of the most valuable productions of Nature. At the time when the flower-stalk is beginning to sprout156, the heart of the plant is cut out, and the juice, which otherwise would have nourished the blossom, collects in the hollow. About three pounds exude157 daily, during a period of two or three months. After standing158 for a short time, the sweet juice undergoes a vinous fermentation, and the stranger, when once accustomed to its disagreeable odour, prefers the pulque to all other wines, and joins in the enthusiastic praises of the Mexican.
The American bromelias likewise resemble the aloes of torrid Africa by the form and arrangement of their leaves. To this useful family belongs the pine-apple (Bromelia Ananas), which grows best and largest in Brazil, where it is so common that the pigs fatten159 on the fruit. Formerly160 confined in our country to the tables of the wealthier classes as long as it was only supplied by our hot-houses, it can now be enjoyed at a very moderate expense, since thousands are imported by every West Indian steamer.
The leaves of several species of bromelia furnish excellent twine161 for ropes. The inhabitants of the banks of the river San Francisco, in Brazil, weave their fishing-nets with the fibres of the Caroa (B. variegata), and the filaments162 of the Crauata de rede (B. sagenaria) furnish a cordage of amazing strength and durability163.
The foliage of the screw-pines, so widely extended over the133 East Indian and South Sea Isles164, where they form a prominent feature in the landscape, closely resembles that of the bromelias, while the stem (round which the serrated leaves ascend165 in spiral convolutions, till they terminate in a pendulous166 crown); the aërial roots, and the fruit, remind one of the palms, the mangroves, and the coniferæ.
The Pandanus odoratissimus, or sweet-smelling screw-pine, whose fruits, when perfectly29 mature, resemble large rich-coloured pine-apples, plays an important part in the household economy of the coral-islanders of the South Sea. The inhabitants of the Mulgrave Archipelago, where the cocoa-nut is rare, live almost exclusively on the juicy pulp167 and the pleasant kernels168 of the fruit. The dried leaves serve to thatch127 their cottages, or are made use of as a material for mats and raiment. The wood is hard and durable169. They string together the beautiful red and yellow-coloured nuts for ornaments170, and wear the flowers as garlands. When the tree is in full blossom, the air around is impregnated with a delicious odour.
The grotesque171 forms of the Cactuses possess the stiff rigidity172 of the aloes. Their fleshy stems, covered with a gray-green coriaceous rind, generally exhibit bunches of hair and thorns instead of leaves. The angular columns of the Cerei, or torch-cactuses, rise to the height of sixty feet,—generally branchless, sometimes strangely ramified, as candelabras, while others creep like ropes upon the ground, or hang, snake-like, from the trees, on which they are parasitically173 rooted. The opuntias are unsymmetrically constructed of thick flat joints springing one from the other, while the melon-shaped Echinocacti and Mammillariæ, longitudinally ribbed or covered with warts174, remain attached to the soil. The dimensions of these monstrous plants are exceedingly variable. One of the Mexican echinocacti (E. Visnaga) measures four feet in height, three in diameter, and weighs about two hundred pounds; while the dwarf175 cactus4 (E. nana) is so small that, loosely rooted in the sand, it frequently remains sticking between the toes of the dogs that pass over it. The splendidly coloured flowers of the cactuses form a strange contrast to the deformity of their stems, and the spectator stands astonished at the glowing life that springs forth from so unpromising a stock. These strange compounds of ugliness and beauty are in many respects useful to man.134 The pulp of the melocacti, which remains juicy during the driest season of the year, is one of the vegetable sources of the wilderness176, and refreshes the traveller after he has carefully removed the thorns. Almost all of them bear an agreeable acid fruit, which, under the name of the Indian fig, is consumed in large quantities in the West Indies and Mexico. The light and incorruptible wood is admirably adapted for the construction of oars177 and many other implements178. The farmer fences his garden with the prickly opuntias; but the services which they render, as the plants on which the valuable cochineal insect feeds and multiplies, are far more important.
The cactuses prefer the most arid179 situation, naked plains, or slopes, where they are fully142 exposed to the burning rays of the sun, and impart a peculiar78 physiognomy to a great part of tropical America.
None of the plants belonging to this family existed in the Old World previously180 to the discovery of America; but some species have since then rapidly spread over the warmer regions of our hemisphere. The Nopal (Cactus Opuntia) skirts the Mediterranean181 along with the American agave, and from the coasts has even penetrated far into the interior of Africa, everywhere maintaining its ground, and conspicuously182 figuring along with the primitive183 vegetation of the land.
Although chiefly tropical, the cactuses have a perpendicular184 range, which but few other families enjoy. From the low sand-coasts of Peru and Bolivia they ascend through vales and ravines to the highest ridges185 of the Andes. Magnificent dark-brown Peireskias (the only cactus genus bearing leaves instead of prickles) bloom on the banks of the Lake of Titicaca, 12,700 feet above the level of the sea; and in the bleak186 Puna,16 even at the very limits of vegetation, the traveller is astonished at meeting with low bushes of cactuses thickly beset187 with yellow prickles.
CEREUS GIGANTEUS.
What a contrast between these deformities and the delicately feathered mimosas, unrivalled among the loveliest children of Flora in the matchless elegance188 of their foliage! Our common acacias give but a faint idea of the beauty which these plants attain under the fostering rays of a tropical sun. In most species135 the branches extend horizontally, or umbrella-shaped, somewhat like those of the Italian pine, and the deep-blue sky shining through the light green foliage, whose delicacy189 rivals the finest embroidery190, has an extremely picturesque191 effect. Endowed with a wonderful sensibility, many of the mimosas seem, as it were, to have outstepped the bounds of vegetable life, and to rival in acuteness of feeling the coral polyps and the sea anemones192 of the submarine gardens.
MIMOSA.
Large tracts101 of country in Brazil are almost entirely covered with sensitive plants. The tramp of a horse sets the nearest ones in motion, and, as if by magic, the contraction193 of the small grey-green leaflets spreads in quivering circles over the field, making one almost believe, with Darwin and Dutrochet, that plants have feeling, or tempting194 one to exclaim with Wordsworth—
‘It is my faith, that every flower Enjoys the air it breathes.’
Among the most remarkable forms of tropical vegetation, the creeping plants, bush-ropes, or lianas (cissus, bauhinia, bignonia, banisteria, passiflora), that contribute so largely to the impenetrability of the forests, hold a conspicuous rank. Often three or four bush-ropes, like strands196 in a cable, join tree to tree, and branch to branch; others, descending198 from on high, take root as soon as their extremity touches the ground, and appear like shrouds199 and stays supporting the mainmast of a line-of-battle ship; while others send out parallel, oblique200, horizontal, and perpendicular shoots in all directions.
No European is able to penetrate31 the intricate network of a forest thus matted together: astonished and despairing, he stands before the dense cordage that impedes201 his path, and, should he attempt to force his way through the maze202, the strong thorns and hooks with which the tropical creepers are generally armed would soon make him repent203 of his boldness. The Brazilian planter never thinks of entering the forest without a large knife, or without being accompanied136 by slaves, who with heavy scythe-like axes attached to long poles, clear the way by severing205 the otherwise impenetrable cordage.
The enormous climbing trees, that stifle206 the life of the mightiest207 giants of the forest, offer a no less wonderful spectacle. At first, these emblems of ingratitude grow straight upwards208 like any feeble shrub209, but as soon as they have found a support in other trees, they begin to extend over their surface; for, while the stems of other plants generally assume a cylindrical210 form, these climbers have the peculiarity of divesting211 themselves of their rind when brought into contact with an extraneous212 body, and of spreading over it, until they at length enclose it in a tubular mass. When, during this process, the powers of the original root are weakened, the trunk sends forth new props213 to restore the equilibrium214; and thus the tough and hardy215 race continually acquires fresh strength for the ruin of its neighbours.
POLANARRUA.
Several species of the fig-tree are peculiarly remarkable for this distinctive216 property, and, from the facility with which their seeds take root where there is a sufficiency of moisture to permit137 of germination217, are formidable assailants of ancient monuments. Sir Emerson Tennent mentions one which had fixed218 itself on the walls of a ruined edifice219 at Polanarrua, and formed one of the most remarkable objects of the place, its roots streaming downwards over the walls as if their wood had once been fluid, and following every sinuosity of the building and terraces till they reached the earth.
On the borders of the Rio Guama, Von Martius saw whole groups of Macauba palms encased in fig-trees that formed thick tubes round the shafts220 of the palms, whose noble crowns rose high above them; and a similar spectacle occurs in India and Ceylon, where the Tamils look with increased veneration221 on their sacred pippul thus united in marriage with the palmyra. After the incarcerated222 trunk has been stifled223 and destroyed, the grotesque form of the parasite224, tubular, cork-screw-like, or otherwise fantastically contorted, and frequently admitting the light through interstices like loopholes in a turret225, continues to maintain an independent existence among the straight-stemmed trees of the forest—the image of an eccentric genius in the midst of a group of sedate226 citizens.
Like the mosses and lichens of our woods, parasites227 of endless variety and almost inconceivable size and luxuriance (ferns, bromelias, tillandsias, orchids, and pothos) cover in the tropical zone the trunks and branches of the forest trees, forming hanging gardens, far more splendid than those of ancient Babylon. While the orchids are distinguished228 by the eccentric forms and splendid colouring of their flowers, sometimes resembling winged insects or birds, the pothos family (caladium, calla, arum, dracontium, pothos) attract attention by the beauty of their large, thick-veined, generally arrow-shaped, digitated, or elongated229 leaves, and form a beautiful contrast to the stiff bromelias or the hairy tillandsias that conjointly adorn230 the knotty231 stems and branches of the ancient trees.
In size of leaf, the Pothos family is surpassed by the large tropical water-plants, the Nymphæas and Nelumbias, among which the Victoria regia, discovered in 1837 by Robert Schomburgk in the river Berbice, enjoys the greatest celebrity. The round light-green leaves of this queen of water-plants measure no less than six feet in diameter, and are surrounded by an elevated rim95 several inches high, and exhibiting the pale, carmine138 red of the under surface. The odorous white blossoms, deepening into roseate hues232, are composed of several hundred petals233; and, measuring no less than fourteen inches in diameter, rival the colossal proportions of the leaves. The Victoria is found all over the Amazon district, but rarely or never in the river itself. It seems to delight in still waters, growing in inlets, lakes, or very quiet branches of the river fully exposed to the sun.
BOTTLE-TREE.
The trunk of several tropical trees offers the remarkable peculiarity of bulging234 out in the middle like a barrel. In the Brazilian forests, the Pao Barrigudo (Chorisia ventricosa) arrests the attention of every traveller by its odd ventricose shape, nearly half as broad in the centre as long, and gradually tapering towards the bottom and the top, whence spring a few thin and scanty branches. It is only by seeing great numbers of these trees all with their character more or less palpable, that one can believe it is not an accidental circumstance in the individual tree, instead of being truly characteristic of the species.
139 The Delabechea, or bottle-tree, discovered by Mr. Mitchell in tropical Australia, has the same lumpish mode of growth. Its wood is of so loose a texture235 that, when boiling water is poured over its shavings, a clear jelly is formed, and becomes a thick viscid mass.
In other trees which, struggling upwards to air and light, attain a prodigious altitude, or from their enormous girth and the colossal expansion of their branches require steadying from beneath, we find buttresses projecting like rays from all sides of the trunk. They are frequently from six to twelve inches thick, and project from five to fifteen feet, and, as they ascend, gradually sink into the bole and disappear at the height of from ten to twenty feet from the ground. By the firm resistance which they offer below, the trees are effectually protected from the leverage236 of the crown, by which they would otherwise be uprooted237. Some of these buttresses are so smooth and flat as almost to resemble sawn planks238; as, for instance, in the Bombax Ceiba, one of the most remarkable examples of this wonderful device of Nature.
SNAKE-TREE.
In other cases we find the roots fantastically spreading and revelling239 in a variety of grotesque shapes, such as we nowhere find in the less exuberant240 vegetation of Europe. Thus, in the india-rubber tree (Ficus elastica), masses of the roots appear above ground, extending on all sides from the base, and writhing241 over the surface in serpentine242 undulations, so that the Indian villagers give it the name of the snake-tree. Sir Emerson Tennent mentions an avenue of these trees leading to the botanical garden of Peradenia, in Ceylon, the roots of which meet from either side of the road, and have so covered the surface as to form a wooden framework, the interstices of which retain the materials that form the roadway. These tangled243 roots sometimes trail to such an extent that they140 have been found upwards of 140 feet in length, whilst the tree itself was not thirty feet high.
The roots of the Mangroves, which in the tropical zone are found fringing the shores of the sea, or the mouths of rivers, wherever the reflux of the tide exposes a broad belt of alluvial244 soil, are admirably adapted for securing a footing on the unstable245 brink246 of the ocean.
MANGROVE.
The growth of these salt-water-loving trees (Rhizophora gymnorrhiza, R. Mangle) is equally peculiar and picturesque. The seeds germinate247 on the branches, and, increasing to a considerable length, finally fall down into the mud, where they stick, with their sharp point buried, and soon take root.
As the young mangrove grows upwards, pendulous roots issue from the trunk and low branches, and ultimately strike into the muddy ground, where they increase to the thickness of a man’s leg; so that the whole has the appearance of a complicated series of loops and arches, from five to ten feet high, supporting the body of the tree like so many artificial stakes.
141 It may easily be imagined what dense and inextricable thickets248, what incomparable breakwaters, plants like these—through whose mazes249 even the light-footed Indian can only penetrate by stepping from root to root—are capable of forming.
Their influence in promoting the growth of land is very great, and in course of time they advance over the shallow borders of the ocean. Their matted roots stem the flow of the waters, and, retaining the earthy particles that sink to the bottom between them, gradually raise the level of the soil. As the new formation progresses, thousands of seeds begin to germinate upon its muddy foundation, thousands of cables descend197, still farther to consolidate250 it; and thus foot by foot, year after year, the mangroves extend their empire and encroach upon the maritime251 domains252.
The enormous deltas253 of many tropical rivers partly owe their immense development to the unceasing expansion of these littoral254 woods; and their influence should by no means be overlooked by the geologist255 when describing the ancient and eternal strife256 between land and ocean.
When the waters retire from under the tangled arcades257 of the mangroves, the black mud, which forms the congenial soil of these plants, appears teeming258 with a boundless259 variety of life. It absolutely swarms260 with the lower marine54 animals, with myriads261 of holothurias, annelides, sea-urchins, entomostraca, paguri, and crabs263, whose often brilliantly coloured carapaces264 form a strong contrast to the black ooze265 in which they are seen to crawl about. Life clings even to the roots and branches bathed by the rising floods; for they are found covered with muscles, barnacles, and oysters266, which thus have the appearance of growing upon trees, and pass one-half of their existence under water, the other in the sultry atmosphere of a tropical shore.
The close-eyed Gudgeon (Periophthalmus), or ‘Jumping Johnny,’ as he is more familiarly named by the sailors, plays a conspicuous part in the animal world of the mangrove swamps, where the uncouth267 form of this strange amphibious fish may be seen jumping about in the mud like a frog, or sliding awkwardly along on its belly268 with a gliding269 motion. By means of its pectoral fins69, it is even enabled to climb142 with great facility among the roots of the mangroves, where it finds a goodly harvest of minute crustaceans270. It must, however, not be supposed that ‘Johnny’ has all the swamp to himself; for though he manages to swallow many a victim, he is not seldom doomed to become the prey271 of creatures more wily or stronger than himself. A large and powerful crab262 of the Grapsus family may often be observed stealing, with an almost imperceptible motion, and in a cautious, sidelong manner, towards a gudgeon basking272 on the shore, and, before the fish has time to plunge273 into the sea, the pincer of the crab secures it in a vice-like gripe, from which it is perfectly hopeless to escape.
‘Johnny’ is a pugnacious274 little fellow, and rather prolonged fights may be observed between him and his brethren. At the mouth of the Zambesi, Dr. Livingstone saw one which, in fleeing from an apparent danger, jumped into a pool a foot square, which another evidently regarded as his by prior discovery. In a twinkling the owner, with eyes flashing fury, and with dorsal275 fin20 bristling276 up in a rage, dashed at the intruding277 foe278. The fight waxed furious. No tempest in a teapot ever equalled the storm of that miniature sea. The warriors279 were now in the water and anon out of it, for the battle raged on sea and shore. They struck hard, they bit each other, until becoming exhausted, they seized each other by the jaws280 like two bull-dogs. They paused for breath, and were at it again as fiercely as before, until the combat ended by the precipitate281 retreat of the invader282.
The vast multitude of marine animals which peoples the mangrove swamps naturally attracts a great number of strand195, lacustrine, and sea birds; for it would be strange, indeed, if guests were wanting where the table is so prodigally283 supplied. The red ibis, the snow-white egrette, the rosy284 spoonbill, the tall flamingo285, and an abundance of herons and other water-fowl, love to frequent the mangrove thickets, enhancing by their magnificent plumage the beauty of the scene. For, however repulsive286 may be the swampy287 ground on which these strange trees delight, yet their bright green foliage, growing in radiated tufts at the ends of the branches, and frequently bespangled with large gaily-coloured flowers, affords a most pleasing spectacle. Many an interesting discovery would143 here, no doubt, reward the naturalist’s attention; but the mangroves know well how to keep their secrets, and to repel288 the curiosity of man. Should he attempt to invade their domains, clouds of bloodthirsty insects would instantly make him repent of his temerity289; for the plague of the mosquitoes is nowhere more dreadful than in the thickets of the semi-aquatic Rhizophoræ. And supposing his scientific zeal290 intense enough to bid defiance291 to the torture of their stings, and to scorn the attacks of every other visible foe—insect or serpent, crocodile or beast of prey—that may be lurking292 among the mangroves, yet the reflection may well bid him pause, that poisonous vapours, pregnant with cholera293 or yellow fever, are constantly rising from that muddy soil. Even in the temperate regions of Europe the emanations from marshy grounds are pregnant with disease, but the malaria294 ascending295 from the sultry morasses296 of the torrid zone is absolutely deadly.
Thus there cannot possibly be a better natural bulwark297 for a land than to be belted with mangroves; and if Borneo, Madagascar, Celebes, and many other tropical islands and coasts, have to the present day remained free from the European yoke298, they are principally indebted for their independence to the miasms and tangles299 of a Rhizophora girdle, bidding defiance alike to the sharp edge of the axe204 or the destructive agency of fire.
As the mangroves are found in places suited to their growth throughout the whole torrid zone, it is not surprising that there are many species, some rising to the height of stately trees, while others are content with a shrub-like growth. Some are peculiar to America, others to the Old World; some grow near the sea, others prefer a brackish300 water and the low swampy banks of rivers.
The Jriarteas and Screw-pines are as singular as the mangroves in the formation of their roots; but those of the Lum, a large tree which Kittlitz found growing on the island of Ualan, are perhaps without a parallel in the vegetable world. Each of the roots, running above-ground for a considerable distance, is surmounted by a perfectly vertical crest301, gradually diminishing in size as the root recedes302 from the trunk, but often three, or even four, feet high near its base. These crests303, which are very thin but perfectly smooth, regularly follow all the sinuosities of the root, and thus form, for a considerable distance144 round the tree, a labyrinth304 of the strangest appearance. Large spaces of swampy ground are often covered with their windings305, and it is no easy matter to walk on the sharp edges of these vertical bands, whose interstices are generally filled with deep mud. On being struck, the larger crests emit a deep sonorous306 sound, like that of a kettledrum.
The thorns and spines with which many European plants are armed, give but a faint idea of the size which these defensive307 weapons attain in the tropical zone. The cactuses, the acacias, and many of the palm-trees, bristle308 with sharp-pointed shafts, affording ample protection against the attacks of hungry animals, and might appropriately be called vegetable hedge-hogs, or porcupines309. The Toddalia aculeata, a climbing plant, very common in the hill-jungles of Ceylon, is thickly studded with knobs, about half an inch high, and from the extremity of each a thorn protrudes310, as large and sharp as the bill of a sparrow-hawk.
The black twigs of the buffalo-thorn (Acacia latronùm), a low shrub abounding312 in northern Ceylon, are beset at every joint126 by a pair of thorns set opposite each other, like the horns of an ox, as sharp as a needle, from two to three inches in length, and thicker at the base than the stem they grow on; and the Acacia tomentosa, another member of the same numerous genus, has thorns so large as to be called the jungle-nail by Europeans, and the elephant-thorn by the natives. In some of these thorny313 plants, the spines grow, not singly, but in branching clusters, each point presenting a spike314 as sharp as a lancet; and where these shrubs315 abound311, they render the forest absolutely impassable, even to animals of the greatest size and strength.
The formidable thorny plants of the torrid zone, which are often made use of by man to protect his fields and plantations316 against wild beasts and robbers, have sometimes even been made to serve as a bulwark against hostile invasions. Thus Sir Emerson Tennent informs us, that, during the existence of the Kandyan kingdom, before its conquest by the British, the frontier forests were so thickened and defended by dense plantations of thorny plants as to form a natural fortification impregnable to the feeble tribes on the other side; and at each pass which led to the level country, movable gates,145 formed of the same thorny beams, were suspended as an ample security against the incursions of the naked and timid lowlanders.
THE LUM TREE.
Poets and moralists, judging by what they see in England, have concluded that fruits of a small size, whose fall cannot be dangerous to man, invariably grow on high trees, while large fruits, such as the pumpkin317, are only found trailing on the ground. But a visit to the tropics would soon convince them of their error, for two of the largest and heaviest fruits known, the Brazilian nut (Bertholletia) and the Durian of the Indian Archipelago, grow on high forest trees, from which they fall down when ripe, and frequently wound or kill the natives. ‘From this,’ says Mr. Wallace, ‘we can learn two things—in the first place, not to draw general conclusions from a locally very limited knowledge of nature, and, secondly318, that trees and fruits, as well as the manifold productions of the animal kingdom, have not been exclusively organised with a reference to man.’
