Ceylon have occasionally, but at rare intervals; suffered severely from
cholera, the disease has in very few instances attacked the officers; or
indeed Europeans in the same grade of life. This is one important
difference to be borne in mind when estimating the comparative risk of
life in India and Ceylon. It must be due to the difference in comforts
and quarters, or more particularly to the exemption from night duty, by
far the most trying of the soldiers' hardships. The small mortality
amongst the officers of European regiments in Ceylon is very
remarkable."--_Note_ by Dr. CAMERON, Army Med. Staff.]
In some of the disorders incidental to the climate, and the treatment of
ulcerations caused by the wounds of the mosquitoes and leeches, the
native Singhalese have a deservedly high reputation; but their practice,
when it depends on specifics, is too empirical to be safely relied on;
and their traditional skill, though boasting a well authenticated
antiquity, achieves few triumphs in competition with the soberer
discipline of European science.
CHAP. III.
VEGETATION.--TREES AND PLANTS.
Although the luxuriant vegetation of Ceylon has at all times been the
theme of enthusiastic admiration, its flora does not probably exceed
3000 phænogamic plants[1]; and notwithstanding that it has a number of
endemic species, and a few genera, which are not found on the great
Indian peninsula, still its botanical features may be described as those
characteristic of the southern regions of Hindustan and the Dekkan. The
result of some recent experiments has, however, afforded a curious
confirmation of the opinion ventured by Dr. Gardner, that, regarding its
botany geographically, Ceylon exhibits more of the Malayan flora and
that of the Eastern Archipelago, than of any portion of India to the
west of it. Two plants peculiar to Malacca, the nutmeg and the
mangustin, have been attempted, but unsuccessfully, to be cultivated in
Bengal; but in Ceylon the former has been reared near Colombo with such
singular success that its produce now begins to figure in the exports of
the island;--and mangustins, which, ten years ago, were exhibited as
curiosities from a single tree in the old Botanic Garden at Colombo, are
found to thrive readily, and they occasionally appear at table,
rivalling in their wonderful delicacy of flavour those which have
heretofore been regarded as peculiar to the Straits.
[Footnote 1: The prolific vegetation of the island is likely to cause
exaggeration in the estimate of its variety. Dr. Gardner, shortly after
his appointment as superintendent of the Botanic Garden at Kandy, in
writing to Sir W. Hooker, conjectured that the Ceylon flora might extend
to 4000 or 5000 species. But from a recent _Report_ of the present
curator, Mr. Thwaites, it appears that the indigenous phænogamic plants
discovered up to August, 1856, was 2670; of which 2025 were
dicotyledonous, and 644 monocotyledonous flowering plants, besides 247
ferns and lycopods. When it is considered that this is nearly double the
indigenous flora of England, and little under _one thirtieth_ of the
entire number of plants hitherto described over the world, the botanical
richness of Ceylon, in proportion to its area, must be regarded as equal
to that of any portion of the globe.]
Up to the present time the botany of Ceylon has been imperfectly
submitted to scientific scrutiny. Linnæus, in 1747, prepared his _Flora
Zeylanica_, from specimens collected by Hermann, which had previously
constituted the materials of the _Thesaurus Zeylanicus_ of Burman and
now form part of the herbarium in the British Museum. A succession of
industrious explorers have been since engaged in following up the
investigation[1]; but, with the exception of an imperfect and
unsatisfactory catalogue by Moon, no enumeration of Ceylon plants has
yet been published. Dr. Gardner had made some progress with a Singhalese
Flora, when his death took place in 1849, an event which threw the task
on other hands, and has postponed its completion for years.[2]
[Footnote 1: Amongst the collections of Ceylon plants deposited in the
Hookerian Herbarium, are those made by General and Mrs. Walker, by Major
Champion (who left the island in 1848), and by Mr. Thwaites, who
succeeded Dr. Gardner in charge of the Royal Botanic Gardens at Kandy.
Moon, who had previously held that appointment, left extensive
collections in the herbarium at Peradenia which have been lately
increased by his successors; and Macrae, who was employed by the
Horticultural Society of London, has enriched their museum with Ceylon
plants. Some admirable letters of Mrs. Walker are printed in HOOKER'S
_Companion to the Botanical Magazine_. They include an excellent account
of the vegetation of Ceylon.]
[Footnote 2: Dr. Gardner, in 1848, drew up a short paper containing
_Some Remarks on the Flora of Ceylon_, which was printed in the appendix
to LEE'S _Translation of Ribeyro_: to this essay, and to his personal
communications during frequent journeys, I am indebted for many facts
incorporated in the following pages.]
From the identity of position and climate, and the apparent similarity
of soil between Ceylon and the southern extremity of the Indian
peninsula, a corresponding agreement might be expected between their
vegetable productions: and accordingly in its aspects and subdivisions
Ceylon participates in those distinctive features which the monsoons
have imparted respectively to the opposite shores of Hindustan. The
western coast being exposed to the milder influence of the south-west
wind, shows luxuriant vegetation, the result of its humid and temperate
climate; whilst the eastern, like Coromandel, has a comparatively dry
and arid aspect, produced by the hot winds which blow for half the year.
The littoral vegetation of the seaborde exhibits little variation from
that common throughout the Eastern archipelago; but it wants the
_Phoenix paludosa_[1], a dwarf date-palm, which literally covers the
islands of the Sunderbunds at the delta of the Ganges. A dense growth of
mangroves[2] occupies the shore, beneath whose overarching roots the
ripple of the sea washes unseen over the muddy beach.
[Footnote 1: Drs. HOOKER and THOMSON, in their _Introductory Essay to
the Flora of India_, speaking of Ceylon, state that the _Nipa fruticans_
(another characteristic palm of the Gangetic delta) and _Cycads_ are
also wanting there, but both these exist (the former abundantly), though
perhaps not alluded to in any work on Ceylon botany to which those
authors had access. In connection with this subject it may be mentioned,
as a fact which is much to be regretted, that, although botanists have
been appointed to the superintendence of the Botanic Gardens at Kandy,
information regarding the vegetation of the island is scarcely
obtainable without extreme trouble and reference to papers scattered
through innumerable periodicals. That the majority of Ceylon plants are
already known to science is owing to the coincidence of their being also
natives of India, whence they have been described; but there has been no
recent attempt on the part of colonial or European botanists even to
throw into a useful form the already published descriptions of the
commoner plants of the island. Such a work would be the first step to a
Singhalese Flora. The preparation of such a compendium would seem, to
belong to the duties of the colonial botanist, and as such it was an
object of especial solicitude to the late superintendent, Dr. Gardner.
But the heterogeneous duties imposed upon the person holding his office
(the evils arising from which are elsewhere alluded to), have hitherto
been insuperable obstacles to the attainment of this object, as they
have also been to the preparation of a systematic account of the general
features of Ceylon vegetation. Such a work is strongly felt to be a
desideratum by numbers of intelligent persons in Ceylon, who are not
accomplished botanists, but who are anxious to acquire accurate ideas as
to the aspects of the flora at different elevations, different seasons,
and different quarters of the island; of the kinds of plants that
chiefly contribute to the vegetation of the coasts, the plains, and
mountains; of the general relations that subsist between them and the
flora of the Carnatic, Malabar, and the Malay archipelago; and of the
more useful plants in science, arts, medicine, and commerce.
To render such a work (however elementary) at once accurate as well as
interesting, would require sound scientific knowledge; and, however
skilfully and popularly written, there would still be portions somewhat
difficult of comprehension to the ordinary reader; but curiosity would
be stimulated by the very occurrence of difficulty, and thus an impulse
might be given to the acquisition of rudimentary botany, which would
eventually enable the inquirer to contribute his quota to the natural
history of Ceylon.
P.S. Since the foregoing was written, Mr. Thwaites has announced the
early publication of a new work on Ceylon plants, to be entitled
_Enumeratio Plantarum Zeylaniæ: with Descriptions of the new and little
known genera and species_, and observations on their habits, uses, &c.
In the Identification of the species Mr. Thwaites is to be assisted by
Dr. Hooker, F.R.S.; and from their conjoint labours we may at last hope
for a production worthy of the subject.]
[Footnote 2: Rhizophera Candelaria, Kandelia Rheedei, Bruguiera
gymnorhiza.]
Retiring from the strand, there are groups of _Sonneratia[1], Avicennia,
Heritiera_, and _Pandanus_; the latter with a stem like a dwarf palm,
round which the serrated leaves ascend in spiral convolutions till they
terminate in a pendulous crown, from which drop the amber clusters of
beautiful but uneatable fruit, with a close resemblance in shape and
colour to that of the pineapple, from which, and from the peculiar
arrangement of the leaves, the plant has acquired its name of the
Screw-pine.
[Footnote 1: At a meeting of the Entomological Society in 1842, Dr.
Templeton sent, for the use of the members, many thin slices of
substance to replace cork-wood as a lining for insect cases and drawers.
Along with the soft wood he sent the following notice:--"In this country
(he writes from Colombo, Ceylon, May 19, 1842), along the marshy banks
of the large rivers, grows a very large handsome tree, named _Sonneratia
acida_, by the younger Linnæus: its roots spread far and wide through
the soft moist earth, and at various distances along send up most
extraordinary long spindle-shaped excrescences four or five feet above
the surface. Of these Sir James Edward Smith remarks 'what these
horn-shaped excrescences are which occupy the soil at some distance from
the base of the tree from a span to a foot in length and of a corky
substance, as described by Rumphins, we can offer no conjecture.' Most
curious things (remarks Dr. Templeton) they are; they all spring very
narrow from the root, expand as they rise, and then become gradually
attenuated, occasionally forking, but never throwing out shoots or
leaves, or in any respect resembling the parent root or wood. They are
firm and close in their texture, nearly devoid of fibrous structure, and
take a moderate polish when cut with a sharp instrument; but for lining
insect boxes and making setting-boards they have no equal in the world.
The finest pin passes in with delightful ease and smoothness, and is
held firmly and tightly so that there is no risk of the insects becoming
disengaged. With a fine saw I form them into little boards and then
smooth them with a sharp case knife, but the London veneering-mills
would turn them out fit for immediate use, without any necessity for
more than a touch of fine glass-paper. Some of my pigmy boards are two
feet long by three and a half inches wide, which is more than sufficient
for our purpose, and to me they have proved a vast acquisition. The
natives call them 'Kirilimow,' the latter syllable signifying
root"--TEMPLETON, _Trans. Ent. Soc._ vol. iii. p. 302.]
A little further inland, the sandy plains are covered by a thorny
jungle, the plants of which are the same as those of the Carnatic, the
climate being alike; and wherever man has encroached on the solitude,
groves of coco-nut palms mark the vicinity of his habitations.
Remote from the sea, the level country of the north has a flora almost
identical with that of Coromandel; but the arid nature of the Ceylon
soil, and its drier atmosphere, is attested by the greater proportion of
euphorbias and fleshy shrubs, as well as by the wiry and stunted nature
of the trees, their smaller leaves and thorny stems and branches.[1]
[Footnote 1: Dr. Gardner.]
Conspicuous amongst them are acacias of many kinds; _Cassia fistula_ the
wood apple (_Feronia elephantum_), and the mustard tree of Scripture
(_Salvadora Persica_), which extends from Ceylon to the Holy Land. The
margosa (_Azadirachta Indica_), the satin wood, the Ceylon oak, and the
tamarind and ebony, are examples of the larger trees; and in the extreme
north and west the Palmyra palm takes the place of the coco-nut, and not
only lines the shore, but fills the landscape on every side with its
shady and prolific groves.
Proceeding southward on the western coast, the acacias disappear, and
the greater profusion of vegetation, the taller growth of the timber,
and the darker tinge of the foliage, all attest the influence of the
increased moisture both from the rivers and the rains. The brilliant
_Ixoras, Erythrinas, Buteas, Jonesias, Hibiscus_, and a variety of
flowering shrubs of similar beauty, enliven the forests with their
splendour; and the seeds of the cinnamon, carried by the birds from the
cultivated gardens near the coasts, have germinated in the sandy soil,
and diversify the woods with the fresh verdure of its polished leaves
and delicately-tinted shoots. It is to be found universally to a
considerable height in the lower range of hills, and thither the Chalias
were accustomed to resort to cut and peel it, a task which was imposed
on them as a feudal service by the native sovereign, who paid an annual
tribute in prepared cinnamon to the Dutch, and to the present time this
branch of the trade in the article continues, but divested of its
compulsory character.
The Dutch, in like manner, maintained, during the entire period of their
rule, an extensive commerce in pepper worts, which still festoon the
forest, but the export has almost ceased from Ceylon. Along with these
the trunks of the larger trees are profusely covered with other delicate
creepers, chiefly Convolvuli and Ipomoeas; and the pitcher-plant
(_Nepenthes distillatoria_) lures the passer-by to halt and conjecture
the probable uses of the curious mechanism, by means of which it distils
a quantity of limpid fluid into the vegetable vases at the extremity of
its leaves. The Orchideæ suspend their pendulous flowers from the angles
of branches, whilst the bare roots and the lower part of the stem are
occasionally covered with fungi of the most gaudy colours, bright red,
yellow, and purple.
Of the east side of the island the botany has never yet been examined by
any scientific resident, but the productions of the hill country have
been largely explored, and present features altogether distinct from
those of the plains. For the first two or three thousand feet the
dissimilarity is less perceptible to an unscientific eye, but as we
ascend, the difference becomes apparent in the larger size of the
leaves, and the nearly uniform colour of the foliage, except where the
scarlet shoots of the ironwood tree (_Mesua ferrea_) seem, like flowers
in their blood-red hue. Here the broad leaves of the wild plantains
(_Musa textilis_) penetrate the soil among the broken rocks; and in
moist spots the graceful bamboo flourishes in groups, whose feathery
foliage waves like the plumes of the ostrich.[1] It is at these
elevations that the sameness of the scenery is diversified by the grassy
patenas before alluded to[2], which, in their aspect, though not their
extent, may be called the Savannahs of Ceylon. Here peaches, cherries,
and other European fruit trees, grow freely; but they become evergreens
in this summer climate, and, exhausted by perennial excitement, and
deprived of their winter repose, they refuse to ripen their fruit.[3] A
similar failure was discovered in some European vines, which were
cultivated at Jaffna; but Mr. Dyke, the government agent, in whose
garden they grew, conceiving that the activity of the plants might be
equally checked by exposing them to an extreme of warmth, as by
subjecting them to cold, tried, with perfect success, the experiment of
laying bare the roots in the strongest heat of the sun. The result
verified his conjecture. The circulation of the sap was arrested, the
vines obtained the needful repose, and the grapes, which before had
fallen almost unformed from the tree, are now brought to thorough
maturity, though inferior in flavour to those produced at home.[4]
[Footnote 1: In the Malayan peninsula the bamboo has been converted into
an instrument of natural music, by perforating it with holes through
which the wind is permitted to sigh; and the effect is described as
perfectly charming. Mr. Logan, who in 1847 visited Naning; contiguous to
the frontier of the European settlement of Malacca, on approaching the
village of Kándáng, was surprised by hearing "the most melodious sounds,
some soft and liquid like the notes of a flute, and others deep and full
like the tones of an organ. They were sometimes low, interrupted, or
even single, and presently they would swell into a grand burst of
mingled melody. On drawing near to a clump of trees; above the branches
of which waved a slender bamboo about forty feet in length, he found
that the musical tones issued from it, and were caused by the breeze
passing through perforations in the stem; the instrument thus formed is
called by the natives the _bulu perindu_, or plaintive bamboo." Those
which Mr. Logan saw had a slit in each joint, so that each stem
possessed fourteen or twenty notes.]
[Footnote 2: See _ante_, p. 24.]
[Footnote 3: The apple-tree in the Peradenia Gardens seems not only to
have become an evergreen but to have changed its character in another
particular; for it is found to send out numerous runners under ground,
which continually rise into small stems and form a growth of shrub-like
plants around the parent tree.]
[Footnote 4: An equally successful experiment, to give the vine an
artificial winter by baring the roots, is recorded by Mr. BALLARD, of
Bombay, in the _Transactions of the Agric. and Hortic. Society of
India_, under date 24th May,1824. Calcutta. 1850. Vol. i. p. 96.]
The tea plant has been raised with complete success in the hills on the
estate of the Messrs. Worms, at Rothschild, in Pusilawa[1]; but the want
of any skilful manipulators to collect and prepare the leaves, renders
it hopeless to attempt any experiment on a large scale, until assistance
can be secured from China, to conduct the preparation.
[Footnote 1: The cultivation of tea was attempted by the Dutch, but
without success.]
Still ascending, at an elevation of 6500 feet, as we approach the
mountain plateau of Neuera-ellia, the dimensions of the trees again
diminish, the stems and branches are covered with orchideæ and mosses,
and around them spring up herbaceous plants and balsams, with here and
there broad expanses covered with _Acanthaceæ_, whose seeds are the
favourite food of the jungle fowl, which are always in perfection during
the ripening of the Nilloo.[1] It is in these regions that the
tree-ferns (_Alsophila gigantea_) rise from the damp hollows, and carry
their gracefully plumed heads sometimes to the height of twenty feet.
[Footnote 1: There are said to be fourteen species of the Nilloo
(_Strobilanthes_) in Ceylon. They form a complete under-growth in the
forest five or six feet in height, and sometimes extending for miles.
When in bloom, their red and blue flowers are a singularly beautiful
feature in the landscape, and are eagerly searched by the honey bees.
Some species are said to flower only once in five, seven, or nine years;
and after ripening their seed they die. This is one reason assigned for
the sudden appearance of the rats, which have been elsewhere alluded to
(vol. i. p. 149, ii. p. 234) as invading the coffee estates, when
deprived of their ordinary food by the decay of the nilloo. It has been
observed that the jungle fowl, after feeding on the nilloo, have their
eyes so affected by it, as to be partially blinded, and permit
themselves to be taken by the hand. Are the seeds of this plant narcotic
like some of the _Solanaceaæ_? or do they cause dilatation of the pupil,
like those of the _Atropa Belladonna_?]
At length in the loftiest range of the hills the Rhododendrons are
discovered; no longer delicate bushes, as in Europe, but timber trees of
considerable height, and corresponding dimensions, and every branch
covered with a blaze of crimson flowers. In these forests are also to be
met with some species of _Michelia_, the Indian representatives of the
Magnolias of North America, several arboreous _myrtaceæ_ and
_ternstromiaceæ_, the most common of which is the camelia-like _Gordonia
Ceylanica_.[1] These and _Vaccinia, Gaultheria, Symploci, Goughia_, and
_Gomphandra_, establish the affinity between the vegetation of this
region and that of the Malabar ranges, the Khasia and Lower Himalaya.[2]
[Footnote 1: Dr. Gardner.]
[Footnote 2: _Introduction to the Flora Indica_ of Dr. HOOKER and Dr.
THOMSON, p. 120. London, 1855.]
Generally speaking, the timber on the high mountains is of little value
for oeconomic purposes. Though of considerable dimensions, it is too
unsubstantial to be serviceable for building or domestic uses; and
perhaps, it may be regarded as an evidence of its perishable nature,
that dead timber is rarely to be seen in any quantity encumbering the
ground, in the heart of the deepest forests. It seems to go to dust
almost immediately after its fall, and although the process of
destruction is infinitely accelerated by the ravages of insects,
especially the white ants (_termites_) and beetles, which instantly
seize on every fallen branch: still, one would expect that the harder
woods would, more or less, resist their attacks till natural
decomposition should have facilitated their operations and would thus
exhibit more leisurely the progress of decay. But here decay is
comparatively instantaneous, and it is seldom that fallen timber is to
be found, except in the last stage of conversion into dust.
Some of the trees in the higher ranges are remarkable for the prodigious
height to which they struggle upwards from the dense jungle towards the
air and light; and one of the most curious of nature's devices, is the
singular expedient by which some families of these very tall and
top-heavy trees throw out buttresses like walls of wood, to support
themselves from beneath. Five or six of these buttresses project like
rays from all sides of the trunk: they are from six to twelve inches
thick, and advance from five to fifteen feet outward; and as they
ascend, gradually sink into the hole 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 steadied, and protected from the
leverage of the crown, by which they would otherwise be uprooted. Some
of these buttresses are so smooth and flat, as almost to resemble sawn
planks.
The greatest ornaments of the forest in these higher regions are the
large flowering trees; the most striking of which is the Rhododendron,
which in Ceylon forms a forest in the mountains, and when covered with
flowers, it seems from a distance as though the hills were strewn with
vermilion. This is the principal tree on the summit of Adam's Peak, and
grows to the foot of the rock on which rests the little temple that
covers the sacred footstep on its crest. Dr. Hooker states that the
honey of its flowers is believed to be poisonous in some parts of
Sikkim; but I never heard it so regarded in Ceylon.
One of the most magnificent of the flowering trees, is the coral
tree[1], which is also the most familiar to Europeans, as the natives of
the low country and the coast, from the circumstance of its stem being
covered with thorns, plant it largely for fences, and grow it in the
vicinity of their dwellings. It derives its English name from the
resemblance which its scarlet flowers present to red coral, and as these
clothe the branches before the leaves appear, their splendour attracts
the eye from a distance, especially when lighted by the full blaze of
the sun.
[Footnote 1: _Erythrina Indica_. It belongs to the pea tribe, and must
not be confounded with the _Jatropha multifida_ which has also acquired
the name of the _coral tree_. Its wood is so light and spongy, that it
is used in Ceylon to form corks for preserve jars; and both there and at
Madras the natives make from it models of their implements of husbandry,
and of their sailing boats and canoes.]
The Murutu[1] is another flowering tree which may vie with the Coral,
the Rhododendron, or the Asoca, the favourite of Sanskrit poetry. It
grows to a considerable height, especially in damp places and the
neighbourhood of streams, and pains have been taken, from appreciation
of its attractions, to plant it by the road side and in other
conspicuous positions. From the points of the branches panicles are
produced, two or three feet in length, composed of flowers, each the
size of a rose and of all shades, from a delicate pink to the deepest
purple. It abounds in the south-west of the island.
[Footnote 1: Lagerstroemia Reginæ.]
The magnificent Asoca[1] is found in the interior, and is cultivated,
though not successfully, in the Peradenia Garden, and in that attached
to Elie House at Colombo. But in Toompane, and in the valley of
Doombera, its loveliness vindicates all the praises bestowed on it by
the poets of the East. Its orange and crimson flowers grow in graceful
racemes, and the Singhalese, who have given the rhododendron the
pre-eminent appellation of the "great red flower," (_maha-rat-mal_,)
have called the Asoca the _diya-rat-mal_ to indicate its partiality for
"moisture," combined with its prevailing hue.
[Footnote 1: Jonesia Asoca.]
But the tree which will most frequently attract the eye of the
traveller, is the kattoo-imbul of the Singhalese[1], one of which
produces the silky cotton which, though incapable of being spun, owing
to the shortness of its delicate fibre, makes the most luxurious
stuffing for sofas and pillows. It is a tall tree covered with
formidable thorns; and being deciduous, the fresh leaves, like those of
the coral tree, do not make their appearance till after the crimson
flowers have covered the branches with their bright tulip-like petals.
So profuse are these gorgeous flowers, that when they fall, the ground
for many roods on all sides is a carpet of scarlet. They are succeeded
by large oblong pods, in which the black polished seeds are deeply
embedded in the floss which is so much prized by the natives. The trunk
is of an unusually bright green colour, and the branches issue
horizontally from the stem, in whorls of threes with a distance of six
or seven feet between each whorl.
[Footnote 1: _Bombax Malabaricus_. As the genus Bombax is confined to
tropical America, the German botanists, Schott and Endlicher, have
assigned to the imbul its ancient Sanskrit name, and described it as
_Salmalia Malabarica_.]
Near every Buddhist temple the priests plant the Iron tree (_Messua
ferrea_)[1] for the sake of its flowers, with which they decorate the
images of Buddha. They resemble white roses, and form a singular
contrast with the buds and shoots of the tree, which are of the deepest
crimson. Along with its flowers the priests use likewise those of the
Champac (_Michelia Champaca_), belonging to the family of magnoliaceæ.
They have a pale yellow tint, with the sweet oppressive perfume which is
celebrated in the poetry of the Hindus. From the wood of the champac the
images of Buddha are carved for the temples.
[Footnote 1: Dr. Gardner supposed the ironwood tree of Ceylon to have
been confounded with the _Messua ferrea_ of Linnæus. He asserted it to
be a distinct species, and assigned to it the well-known Singhalese name
"_nagaha_," or _iron-wood tree_. But this conjecture has since proved
erroneous.]
The celebrated Upas tree of Java (_Antiaris toxicaria_) which has been
the subject of so many romances, exploded by Dr. Horsfield[1], was
supposed by Dr. Gardner to exist in Ceylon, but more recent scrutiny has
shown that what he mistook for it, was an allied species, the _A.
saccidora_, which grows at Kornegalle, and in other parts of the island;
and is scarcely less remarkable, though for very different
characteristics. The Ceylon species was first brought to public notice
by E. Rawdon Power, Esq., government agent of the Kandyan province, who
sent specimens of it, and of the sacks which it furnishes, to the branch
of the Asiatic Society at Colombo. It is known to the Singhalese by the
name of "ritigaha," and is identical with the _Lepurandra saccidora_,
from which the natives of Coorg, like those of Ceylon, manufacture an
ingenious substitute for sacks by a process which is described by Mr.
Nimmo.[2] "A branch is cut corresponding to the length and breadth of
the bag required, it is soaked and then beaten with clubs till the liber
separates from the timber. This done, the sack which is thus formed out
of the bark is turned inside out, and drawn downwards to permit the wood
to be sawn off, leaving a portion to form the bottom which is kept
firmly in its place by the natural attachment of the bark."
[Footnote 1: The vegetable poisons, the use of which is ascribed to the
Singhalese, are chiefly the seeds of the _Datura_, which act as a
powerful narcotic, and those of the _Croton tiglium_, the excessive
effect of which ends in death. The root of the _Nerium odorum_ is
equally fatal, as is likewise the exquisitely beautiful _Gloriosa
superba_, whose brilliant flowers festoon the jungle in the plains of
the low country. See Bennett's account of the _Antiaris_, in HORSFIELD'S
_Plantæ Javanicæ_.]
[Footnote 2: Catalogue of Bombay Plants, p. 193. The process in Ceylon
is thus described in Sir W. HOOKER'S _Report on the Vegetable Products_
exhibited in Paris in 1855: "The trees chosen for the purpose measure
above a foot in diameter. The felled trunks are cut into lengths, and
the bark is well beaten with a stone or a club till the parenchymatous
part comes off, leaving only the inner bark attached to the wood; which
is thus easily drawn out by the hand. The bark thus obtained is fibrous
and tough, resembling a woven fabric: it is sewn at one end into a sack,
which is filled with sand, and dried in the sun."]
As we descend the hills the banyans[1] and a variety of figs make their
appearance. They are the Thugs of the vegetable world, for although not
necessarily epiphytic, it may be said that in point of fact no single
plant comes to perfection, or acquires even partial development, without
the destruction of some other on which to fix itself as its supporter.
The family generally make their first appearance as slender roots
hanging from the crown or trunk of some other tree, generally a palm,
among the moist bases of whose leaves the seed carried thither by some
bird which had fed upon the fig, begins to germinate. This root
branching as it descends, envelopes the trunk of the supporting tree
with a network of wood, and at length penetrating the ground, attains
the dimensions of a stem. But unlike a _stem_ it throws out no buds,
leaves, or flowers; the true stem, with its branches, its foliage, and
fruit, springs upwards from the crown of the tree whence the root is
seen descending; and from it issue the pendulous rootlets, which, on
reaching the earth, fix themselves firmly and form the marvellous growth
for which the banyan is so celebrated.[2] In the depth of this grove,
the original tree is incarcerated till, literally strangled by the folds
and weight of its resistless companion, it dies and leaves the fig in
undisturbed possession of its place. It is not unusual in the forest to
find a fig-tree which had been thus upborne till it became a standard,
now forming a hollow cylinder, the centre of which was once filled by
the sustaining tree: but the empty walls form a circular network of
interlaced roots and branches; firmly agglutinated under pressure, and
admitting the light through interstices that look like loopholes in a
turret.
[Footnote 1: Ficus Indica.]
[Footnote 2: I do not remember to have seen the following passage from
Pliny referred to as the original of Milton's description of this
marvellous tree:--
"Ipsa se serens, vastis diffunditur ramis: quorum imi adeo in terram
curvantur, ut annuo spatio infigantur, novamque sibi _propaginem faciant
circa parentem in orbem._ Intra septem eam _æstivant pastores_, opacam
pariter et munitam vallo arboris, decora specie subter intuenti,
proculve, _fornicato_ arbore. Foliorum latitudo _peltæ effigiem
Amazonicæ_ habet," &c.--PLINY, 1. xii. c. 11.
"The fig-tree--not that kind for fruit renowned,
But such as at this day to Indians known,
In Malabar or Dekkan spreads her arms,
Branching so broad and long, that on the ground
The bended twigs take root, and _daughters grow
About the mother tree: a pillar'd_ shade
High over arched and echoing walks between.
There oft the Indian herdsman, shunning heat,
Shelters in cool and _tends his pasturing flocks_
At loop-holes cut through thickest shade. These leaves
They gathered; broad as _Amazonian targe:_
And with what skill they had, together sewed
To gird their waist," &c.
_Par. Lost_, ix. 1100.
Pliny's description is borrowed, with some embellishments, from
THEOPHRASTUS _de. Nat. Plant._ l. i. 7. iv. 4.]
[Illustration: MARRIAGE OF THE FIG-TREE AND THE PALM.]
Another species of the same genus, _F. repens,_ is a fitting
representative of the English ivy, and is constantly to be seen
clambering over rocks, turning through heaps of stones, or ascending
some tall tree to the height of thirty or forty feet, while the
thickness of its own stem does not exceed a quarter of an inch.
The facility with which the seeds of the fig-tree take root where there
is a sufficiency of moisture to permit of germination, has rendered them
formidable assailants of the ancient monuments throughout Ceylon. The
vast mounds of brickwork which constitute the remains of the Dagobas at
Anarajapoora and Pollanarrua are covered densely with trees, among which
the figs are always conspicuous. One, which has fixed itself on the
walls of a ruined edifice at the latter city, forms one of the most
remarkable objects of the place--its roots streaming downwards over the
walls as if their wood had once been fluid, follow every sinuosity of
the building and terraces till they reach the earth.
[Illustration: A FIG TREE ON THE RUINS OF POLLANARRUA.]
To this genus belongs the Sacred Bo-tree of the Buddhists, _Ficus
religiosa,_ which is planted close to every temple, and attracts almost
as much veneration as the statue of the god himself. At Anarajapoora is
still preserved the identical tree said to have been planted 288 years
before the Christian era.[1]
[Footnote 1: For a memoir of this celebrated tree, see the account of
Anarajapoora, Vol. II. p. 10.]
Although the India-rubber tree (_F. elastica_) is not indigenous to
Ceylon, it is now very widely diffused over the island. It is remarkable
for the pink leathery covering which envelopes the leaves before
expansion, and for the delicate tracing of the nerves which run in
equi-distant rows at right angles from the mid-rib. But its most
striking feature is the exposure of its roots, masses of which appear
above ground, extending on all sides from the base, and writhing over
the surface in undulations--
"Like snakes in wild festoon,
In ramous wrestlings interlaced,
A forest Laocoon."[1]
[Footnote 1: HOOD's poem of _The Elm Tree._]
So strong, in fact, is the resemblance, that the villagers give it the
name of the "Snake-tree." One, which grows close to Cotta, at the Church
Missionary establishment within a few miles of Colombo, affords a
remarkable illustration of this peculiarity.
[Illustration: THE SNAKE-TREE.]
There is an avenue of these trees leading to the Gardens of Peradenia,
the roots of which meet from either side of the road, and have so
covered the surface by their agglutinated reticulations as to form a
wooden framework, the interstices of which retain the materials that
form the roadway.[1]
[Footnote 1: Mr. Ferguson of the Surveyor-General's Department, assures
me that he once measured the root of a small wild fig-tree, growing in a
patena at Hewahette, and found it upwards of 140 feet in length, whilst
the tree itself was not 30 feet high.]
The Kumbuk of the Singhalese (called by the Tamils Maratha-maram)[1] is
one of the noblest and most widely distributed trees in the island; it
delights in the banks of rivers and moist borders of tanks and canals;
it overshadows the stream of the Mahawelli-ganga, almost from Kandy to
the sea; and it stretches its great arms above the still water of the
lakes on the eastern side of the island.
[Footnote 1: Pentaptera tomentosa _(Rox.)_.]
One venerable patriarch of this species, which grows at Mutwal, within
three miles of Colombo, towers to so great a height above the
surrounding forests of coconut palms, that it forms a landmark for the
native boatmen, and is discernible from Negombo, more than twenty miles
distant. The circumference of its stem, as measured by Mr. W. Ferguson,
in 1850, was forty-five feet close to the earth, and seven yards at
twelve feet above the ground.
The timber, which is durable, is applied to the carving of idols for the
temples, besides being extensively used for less dignified purposes; but
it is chiefly prized for the bark, which is sold as a medicine, and, in
addition to yielding a black dye, it is so charged with calcareous
matter that its ashes, when burnt, afford a substitute for the lime
which the natives chew with their betel.
Some of the trees found in the forests of the interior are remarkable
for the curious forms in which they produce their seeds. One of these,
which sometimes grows to the height of one hundred feet without throwing
out a single branch, has been confounded with the durian of the Eastern
Archipelago, or supposed to be an allied species[1], but it differs from
it in the important particular that its fruit is not edible. The real
durian is not indigenous to Ceylon, but was brought there by the
Portuguese in the sixteenth century.[2] It has been very recently
re-introduced, and is now cultivated successfully. The native name for
the Singhalese tree, "Katu-boeda," denotes the prickles that cover its
fruit, which is as large as a coco-nut, and set with thorns each nearly
an inch in length.
[Footnote 1: It is the _Cullenia excelsa_ of WIGHT's _Icones, &c._
(761-2).]
[Footnote 2: PORCACCHI, in his _Isolario_, written in the sixteenth
century, enumerates the true durian as being then amongst the ordinary
fruit of Ceylon.--"Vi nasce anchora un frutto detto Duriano, verde et
grande come quei cocomeri, che a Venetia son chiamati angurie: in mezo
del quale trouano dentro cinque frutti de sapor molto excellente."--Lib.
iii. p. 188. Padua, A.D. 1619.]
The _Sterculia foetida,_ one of the finest and noblest of the Ceylon
forest-trees, produces from the end of its branches large bunches of
dark purple flowers of extreme richness and beauty; but emitting a
stench so intolerable as richly to entitle it to its very characteristic
botanical name. The fruit is equally remarkable, and consists of several
crimson cases of the consistency of leather, within which are enclosed a
number of black bean-like seeds: these are dispersed by the bursting of
their envelope, which splits open to liberate them when sufficiently
ripened.
The Moodilla (_Barringtonia speciosa_) is another tree which attracts
the eye of the traveller, not less from the remarkably shaped fruit
which it bears than from the contrast between its dark glossy leaves and
the delicate flowers which they surround. The latter are white, tipped
with crimson, but the petals drop off early, and the stamens, of which
there are nearly a hundred to each flower, when they fall to the ground
might almost be mistaken for painters' brushes. The tree (as its name
implies) loves the shore of the sea, and its large quadrangular fruits,
of pyramidal form, being protected by a hard fibrous covering, are
tossed by the waves till they root themselves on the beach. It grows
freely at the mouths of the principal rivers on the west coast, and
several noble specimens of it are found near the fort of Colombo.
The Goda-kaduru, or _Strychnos nux-vomica_ is abundant in these
prodigious forests, and has obtained an European celebrity on account of
its producing the poisonous seeds from which strychnine is extracted.
Its fruit, which it exhibits in great profusion, is of the size and
colour of a small orange, within which a pulpy substance envelopes the
seeds that form the "nux-vomica" of commerce. It grows in great
luxuriance in the vicinity of the ruined tanks throughout the Wanny, and
on the west coast as far south as Negombo. It is singular that in this
genus there should be found two plants, the seeds of one being not only
harmless but wholesome, and that of the other the most formidable of
known poisons.[1] Amongst the Malabar immigrants there is a belief that
the seeds of the goda-kaduru, if habitually taken, will act as a
prophylactic against the venom of the cobra de capello; and I have been
assured that the coolies coming from the coast of India accustom
themselves to eat a single seed per day in order to acquire the desired
protection from the effects of this serpent's bite.[2]
[Footnote 1: The _tettan-cotta,_ the use of which is described in Vol.
II. Pt. ix. ch. i. p. 411, when applied by the natives to clarify muddy
water, is the seed of another species of strychnos, _S. potatorum_. The
Singhalese name is _ingini_ (_tettan-cotta_ is Tamil).]
[Footnote 2: In India, the distillers of arrack from the juice of the
coco-nut palm are said, by Roxburgh, to introduce the seeds of the
strychnus, in order to increase the intoxicating power of the spirit.]
In these forests the Euphorbia[1], which we are accustomed to see only
as a cactus-like green-house plant, attains the size and strength of a
small timber-tree; its quadrangular stem becomes circular and woody, and
its square fleshy shoots take the form of branches, or rise with a
rounded top as high as thirty feet.[2]
[Footnote 1: E. Antiquorun.]
[Footnote 2: Amongst the remarkable plants of Ceylon, there is one
concerning which a singular error has been perpetuated in botanical
works from the time of Paul Hermann, who first described it in 1687, to
the present. I mean the _kiri-anguna_ (Gymnema lactiferum), evidently a
form of the G. sylvestre, to which has been given the name of the
_Ceylon cow-tree_; and it is asserted that the natives drink its juice
as we do milk. LOUDON (_Ency. of Plants_, p. 197) says, "The milk of the
_G. lactiferum_ is used instead of the vaccine ichor, and the leaves are
employed in sauces in the room of cream." And LINDLEY, in his _Vegetable
Kingdom_, in speaking of the Asclepiads, says, "the cow plant of Ceylon,
'kiri-anguna,' yields a milk of which the Singhalese make use for food;
and its leaves are also used when boiled." Even in the _English
Cyclopædia_ of CHARLES KNIGHT, published so lately as 1854, this error
is repeated. (See art. Cow-tree, p. 178.) But this in altogether a
mistake;--the Ceylon plant, like many others, has acquired its epithet
of _kiri_, not from the juices being susceptible of being used as a
substitute for milk, but simply from its resemblance to it in colour and
consistency. It is a creeper, found on the southern and western coasts,
and used medicinally by the natives, but never as an article of food.
The leaves, when chopped and boiled, are administered to nurses by
native practitioners, and are supposed to increase the secretion of
milk. As to its use, as stated by London, in lieu of the vaccine matter,
it is altogether erroneous. MOON, in his _Catalogue of the Plants of
Ceylon_, has accidentally mentioned the kiri-anguna twice, being misled
by the Pali synonym "kiri-hangula": they are the same plant, though he
has inserted them as different, p. 21.]
But that which arrests the attention even of an indifferent passer-by is
the endless variety and almost inconceivable size and luxuriance of the
_climbing plants and epiphytes_ which live upon the forest trees in
every part of the island. It is rare to see a single tree without its
families of dependents of this description, and on one occasion I
counted on a single prostrate stem no less than sixteen species of
Capparis, Beaumontia, Bignonia, Ipomoea, and other genera, which, in its
fall, it had brought along with it to the ground. Those which are free
from climbing plants have their higher branches and hollows occupied by
ferns and orchids, of which latter the variety is endless in Ceylon,
though the beauty of their flower is not equal to those of Brazil and
other tropical countries. In the many excursions which I made with Dr.
Gardner he added numerous species to those already known, including the
exquisite _Saccolabium guttatum_, which we came upon in the vicinity of
Bintenne, but which had before been discovered in Java and the mountains
of northern India. Its large groups of lilac flowers hung in rich
festoons from the branches as we rode under them, and caused us many an
involuntary halt to admire and secure the plants.
A rich harvest of botanical discovery still remains for the scientific
explorer of the districts south and east of Adam's Peak, whence Dr.
Gardner's successor, Mr. Thwaites, has already brought some remarkable
species. Many of the Ceylon orchids, like those of South America,
exhibit a grotesque similitude to various animals; and one, a
_Dendrobium_., which the Singhalese cultivate in the palms near their
dwelling, bears a name equivalent to the _White-pigeon flower,_ from the
resemblance which its clusters present to a group of those birds in
miniature clinging to the stem with wings at rest.
But of this order the most exquisite plant I have seen is the
_Anæctochilus setaceus_, a terrestrial orchid which is to be found about
the moist roots of the forest trees, and has drawn the attention of even
the apathetic Singhalese, among whom its singular beauty has won for it
the popular name of the Wanna Raja, or "King of the Forest." It is
common in humid and shady places a few miles removed from the sea-coast;
its flowers have no particular attraction, but its leaves are perhaps
the most exquisitely formed in the vegetable kingdom; their colour
resembles dark velvet, approaching to black, and reticulated over all
the surface with veins of ruddy gold.[1]
[Footnote 1: There is another small orchid bearing a slight resemblance
to the wanna raja, which is often found growing along with it, called by
the Singhalese iri raja, or "striped king." Its leaves are somewhat
bronzed, but they are longer and narrower than those of the wanna raja;
and, as its Singhalese name implies, it has two white stripes running
through the length of each. They are not of the same genus; the wanna
raja being the only species of _Anæctochilus_ yet found in Ceylon.]
The branches of all the lower trees and brushwood are so densely covered
with convolvuli, and similar delicate climbers of every colour, that
frequently it is difficult to discover the tree which supports them,
owing to the heaps of verdure under which it is concealed. One very
curious creeper, which always catches the eye, is the square-stemmed
vine[1], whose fleshy four-sided runners climb the highest trees, and
hang down in the most fantastic bunches. Its stem, like that of another
plant of the same genus (the _Vitis Indica_), when freshly cut, yields a
copious draught of pure tasteless fluid, and is eagerly sought after by
elephants.
[Footnote 1: Cissus edulis, _Dalz_.]
But it is the trees of older and loftier growth that exhibit the rank
luxuriance of these wonderful epiphytes in the most striking manner.
They are tormented by climbing plants of such extraordinary dimensions
that many of them exceed in diameter the girth of a man; and these
gigantic appendages are to be seen surmounting the tallest trees of the
forest, grasping their stems in firm convolutions, and then flinging
their monstrous tendrils over the larger limbs till they reach the top,
whence they descend to the ground in huge festoons, and, after including
another and another tree in their successive toils, they once more
ascend to the summit, and wind the whole into a maze of living network
as massy as if formed by the cable of a line-of-battle ship. When,
by-and-by, the trees on which this singular fabric has become suspended
give way under its weight, or sink by their own decay, the fallen trunk
speedily disappears, whilst the convolutions of climbers continue to
grow on, exhibiting one of the most marvellous and peculiar living
mounds of confusion that it is possible to fancy. Frequently one of
these creepers may be seen holding by one extremity the summit of a tall
tree, and grasping with the other an object at some distance near the
earth, between which it is strained as tight and straight as if hauled
over a block. In all probability the young tendril had been originally
fixed in this position by the wind, and retained in it till it had
gained its maturity, where it has the appearance of having been
artificially arranged as if to support a falling tree.
This peculiarity of tropical vegetation has been turned to profitable
account by the Ceylon woodmen, employed by the European planters in
felling forest trees, preparatory to the cultivation of coffee. In this
craft they are singularly expert, and far surpass the Malabar coolies,
who assist in the same operations. In steep and mountainous places where
the trees have been thus lashed together by the interlacing climbers,
the practice is to cut halfway through each stem in succession, till an
area of some acres in extent is prepared for the final overthrow. Then
severing some tall group on the eminence, and allowing it in its descent
to precipitate itself on those below, the whole expanse is in one moment
brought headlong to the ground; the falling timber forcing down those
beneath it by its weight, and dragging those behind to which it is
harnessed by its living attachments. The crash occasioned by this
startling operation is so deafeningly loud, that it is audible for two
or three miles in the clear and still atmosphere of the hills.
One monstrous creeping plant called by the Kandyans the Maha-pus-wael,
or "Great hollow climber,"[1] has pods, some of which I have seen fully
five feet long and six inches broad, with beautiful brown beans, so
large that the natives hollow them out, and carry them as tinder-boxes.
[Footnote 1: _Entada pursætha_. The same plant, when found in lower
situations, where it wants the soil and moisture of the mountains, is so
altered in appearance that the natives call it the "heen-pus-wael;" and
even botanists have taken it for a distinct species. The beautiful
mountain region of Pusilawa, now familiar as one of the finest coffee
districts in Ceylon, in all probability takes its name from the giant
bean, "Pus-waelawa."]
Another climber of less dimensions[1], but greater luxuriance, haunts
the jungle, and often reaches the tops of the highest trees, whence it
suspends large bunches of its yellow flowers, and eventually produces
clusters of prickly pods containing greyish-coloured seeds, less than an
inch in diameter, which are so strongly coated with silex, that they are
said to strike fire like a flint.
[Footnote 1: Guilandina Bonduc.]
One other curious climber is remarkable for the vigour and vitality of
its vegetation, a faculty in which it equals, if it do not surpass, the
banyan. This is the _Cocculus cordifolius_, the "rasa-kindu" of the
Singhalese, a medicinal plant which produces the _guluncha_ of Bengal.
It is largely cultivated in Ceylon, and when it has acquired the
diameter of half an inch, it is not unusual for the natives to cut from
the main stem a portion of from twenty to thirty feet in length, leaving
the dissevered plant suspended from the branches of the tree which
sustained it. The amputation naturally serves for a time to check its
growth, but presently small rootlets, not thicker than a pack-thread,
are seen shooting downwards from the wounded end; these swing in the
wind till, reaching the ground, they attach themselves in the soil, and
form new stems, which in turn, when sufficiently grown, are cut away and
replaced by a subsequent growth. Such is its tenacity of life, that when
the Singhalese wish to grow the _rasa-kindu_, they twist several yards
of the stem into a coil of six or eight inches in diameter, and simply
hang it on the branch of a tree, where it speedily puts forth its large
heart-shaped leaves, and sends down its rootlets to the earth.
The ground too has its creepers, and some of them very curious. The most
remarkable are the ratans, belonging to the Calamus genus of palms. Of
these I have seen a specimen 250 feet long and an inch in diameter,
without a single irregularity, and no appearance of foliage other than
the bunch of feathery leaves at the extremity.
The strength of these slender plants is so extreme, that the natives
employ them with striking success in the formation of bridges across the
water-courses and ravines. One which crossed the falls of the
Mahawelliganga, in the Kotmahe range of hills, was constructed with the
scientific precision of an engineer's work. It was entirely composed of
the plant, called by the natives the "Waywel," its extremities fastened
to living trees, on the opposite sides of the ravine through which a
furious and otherwise impassable mountain torrent thundered and fell
from rock to rock with a descent of nearly 100 feet. The flooring of
this aerial bridge consisted of short splints of wood, laid
transversely, and bound in their places by thin strips of the waywel
itself. The whole structure vibrated and swayed with fearful ease, but
the coolies traversed it though heavily laden; and the European, between
whose estate and the high road it lay, rode over it daily without
dismounting.
Another class of trees which excites the astonishment of an European,
are those whose stems are protected, as high as cattle can reach, by
thorns, which in the jungle attain a growth and size quite surprising.
One species of palm[1], the _Caryota horrida,_ often rises to a height
of fifty feet, and has a coating of thorns for about six or eight feet
from the ground, each about an inch in length, and so densely covering
the stem that the bark is barely visible.
[Footnote 1: This palm I have called a _Caryota_ on the authority of Dr.
GARDNER, and of MOON'S _Catalogue_; but I have been informed by Dr.
HOOKER and Mr. THWAITES that it is an _Areca_. The natives identify it
with the Caryota, and call it the "katu-kittul."]
A climbing plant, the "Kudu-miris" of the Singhalese[1], very common in
the hill jungles, with a diameter of three or four inches, is thickly
studded with knobs about half an inch high, and from the extremity of
each a thorn protrudes, as large and sharp as the bill of a
sparrow-hawk. It has been the custom of the Singhalese from time
immemorial, to employ the thorny trees of their forests in the
construction of defences against their enemies. The _Mahawanso_ relates,
that in the civil wars, in the reign of Prakrama-bahu in the twelfth
century, the inhabitants of the southern portion of the island
intrenched themselves against his forces behind moats filled with
thorns.[2] And at an earlier period, during the contest of Dutugaimunu
with Elala, the same authority states, that a town which he was about to
attack was "surrounded on all sides by the thorny _Dadambo creeper_
(probably Toddalia aculeata), within which was a triple hue of
fortifications, with one gate of difficult access."[3]
[Footnote 1: Toddalia aculeata.]
[Footnote 2: _Mahawanso_ ch. lxxiv.]
[Footnote 3: _Mahawanso_ ch. xxv.]
During the existence of the Kandyan kingdom as an independent state,
before its conquest by the British, the frontier forests were so
thickened and defended by dense plantations of these thorny palms and
climbers at different points, as to exhibit a natural fortification
impregnable to the feeble tribes on the other side, and at each pass
which led to the level country, movable gates, formed of the same
formidable thorny beams, were suspended as an ample security against the
incursions of the naked and timid lowlanders.[1]
[Footnote 1: The kings of Kandy maintained a regulation "that no one; on
pain of death, should presume to cut a road through the forest wider
than was sufficient for one person to pass."--WOLF'S _Life and
Adventures_, p. 308.]
The pasture grounds throughout the vicinity of Jaffna abound in a low
shrub called the Buffalo-thorn[1], the black twigs of which are beset at
every joint 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.
[Footnote 1: _Acacia latronum._]
The _Acacia tomentosa_ is of the same genus, with thorns so large as to
be called the "_jungle-nail_" by Europeans. It is frequent in the woods
of Jaffna and Manaar, where it bears the Tamil name of _Aani mulla_, or
"elephant thorn." In some of these thorny plants, as in the _Phoberos
Goertneri, Thun._,[1] the spines grow not singly, but in branching
clusters, each point presenting a spike as sharp as a lancet; and where
these formidable shrubs abound they render the forest absolutely
impassable, even to the elephant and to animals of great size and force.
[Footnote 1: Mr. Wm. Ferguson writes to me, "This is the famous
_Katu-kurundu_, or 'thoray cinnamon,' of the Singhalese, figured and
described by Gaertner as the _Limonia pusilla_, which after a great deal
of labour and research I think I have identified as the _Phoberos
macrophyllus_" (W. and A. Prod. p. 30). Thunberg alludes to it
(_Travels_, vol. iv.)--"Why the Singhalese have called it a cinnamon, I
do not know, unless from some fancied similarity in its seeds to those
of the cinnamon laurel."]
The family of trees which, from their singularity as well as their
beauty, most attract the eye of the traveller in the forests of Ceylon,
are the palms, which occur in rich profusion, although, of upwards of
six hundred species which are found in other countries, not more than
ten or twelve are indigenous to the island.[1] At the head of these is
the coco-nut, every particle of whose substance, stem, leaves, and
fruit, the Singhalese turn to so many accounts, that one of their
favourite topics to a stranger is to enumerate the _hundred_ uses to
which they tell us this invaluable tree is applied.[2]
[Footnote 1: Mr. Thwaites has enumerated fifteen species (including the
coco-nut, and excluding the _Nipa fruticans_, which more properly
belongs to the family of screw-pines): viz. Areca, 4; Caryota, 1;
Calamus, 5; Borassus, 1; Corypha, 1; Phoenix, 2; Cocos, 1.]
[Footnote 2: The following are only a few of the countless uses of this
invaluable tree. The _leaves_, for roofing, for mats, for baskets,
torches or chules, fuel, brooms, fodder for cattle, manure. The _stem of
the leaf_, for fences, for pingoes (or yokes) for carrying burthens on
the shoulders, for fishing-rods, and innumerable domestic utensils. The
_cabbage_ or cluster of unexpended leaves, for pickles and preserves.
The _sap_ for _toddy_, for distilling arrack, and for making vinegar,
and sugar. The _unformed nut_, for medicine and sweetmeats. The _young
nut_ and its milk, for drinking, for dessert; the _green husk_ for
preserves. The _nut_, for eating, for curry, for milk, for cooking. The
_oil_, for rheumatism, for anointing the hair, for soap, for candles,
for light; and the _poonak_, or refuse of the nut after expressing the
oil, for cattle and poultry. The _shell of the nut_, for drinking cups,
charcoal, tooth-powder, spoons, medicine, hookahs, beads, bottles, and
knife-handles. The _coir_, or fibre which envelopes the shell within the
outer husk, for mattresses, cushions, ropes, cables, cordage, canvass,
fishing-nets, fuel, brushes, oakum, and floor mats. The _trunk_, for
rafters, laths, railing, boats, troughs, furniture, firewood; and when
very young, the first shoots, or cabbage, as a vegetable for the table.
The entire list, with a Singhalese enthusiast, is an interminable
narration of the virtues of his favourite tree.]
The most majestic and wonderful of the palm tribe is the _talpat_ or
_talipat_[1], the stem of which sometimes attains the height of 100
feet, and each of its enormous fan-like leaves, when laid upon the
ground, will form a semicircle of 16 feet in diameter, and cover an area
of nearly 200 superficial feet. The tree flowers but once, and dies; and
the natives firmly believe that the bursting of the shadix is
accompanied by a loud explosion. The leaves alone are converted by the
Singhalese to purposes of utility. Of them they form coverings for their
houses, and portable tents of a rude but effective character; and on
occasions of ceremony, each chief and headman on walking abroad is
attended by a follower, who holds above his head an
elaborately-ornamented fan, formed from a single leaf of the talpat.
[Footnote 1: Corypha umbraculifera, _Linn._]
But the most interesting use to which they are applied is as substitutes
for paper, both for books and for ordinary purposes. In the preparation
of _olas_, which is the term applied to them when so employed, the
leaves are taken whilst still tender, and, after separating the central
ribs, they are cut into strips and boiled in spring water. They are
dried first in the shade, and afterwards in the sun, then made into
rolls, and kept in store, or sent to the market for sale. Before they
are fit for writing on they are subjected to a second process, called
_madema_. A smooth plank of areca-palm is tied horizontally between two
trees, each ola is then damped, and a weight being attached to one end
of it, it is drawn backwards and forwards across the edge of the wood
till the surface becomes perfectly smooth and polished; and during the
process, as the moisture dries up, it is necessary to renew it till the
effect is complete. The smoothing of a single ola will occupy from
fifteen to twenty minutes.[1]
[Footnote 1: See Vol. II. p. 528.]
The finest specimens in Ceylon are to be obtained at the Panselas, or
Buddhist monasteries; they are known as _pusk[(o]la_ and are prepared by
the Samanera priests (novices) and the students, under the
superintendence of the priests.
The raw leaves, when dried without any preparation, are called
_karak[(o]la_, and, like the leaves of the palmyra, are used only for
ordinary purposes by the Singhalese; but in the Tamil districts, where
palmyras are abundant, and talpat palms rare, the leaves of the former
are used for books as well as for letters.
The _palmyra_[1] is another invaluable palm, and one of the most
beautiful of the family. It grows in such profusion over the north of
Ceylon, and especially in the peninsula of Jaffna, as to form extensive
forests, whence its timber is exported for rafters to all parts of the
island, as well as to the opposite coast of India, where, though the
palmyra grows luxuriantly, its wood, from local causes, is too soft and
perishable to be used for any purpose requiring strength and durability,
qualities which, in the palmyra of Ceylon, are pre-eminent. To the
inhabitants of the northern provinces this invaluable tree is of the
same importance as the coco-nut palm is to the natives of the south. Its
fruit yields them food and oil; its juice "palm wine" and sugar; its
stem is the chief material of their buildings; and its leaves, besides
serving as roofs to their dwellings and fences to their farms, supply
them with matting and baskets, with head-dresses and fans, and serve as
a substitute for paper for their deeds and writings, and for the sacred
books, which contain the traditions of their faith. It has been said
with truth that a native of Jaffna, if he be contented with ordinary
doors and mud walls, may build an entire house (as he wants neither
nails nor iron work), with walls, roof, and covering from the Palmyra
palm. From this same tree he may draw his wine, make his oil, kindle his
fire, carry his water, store his food, cook his repast, and sweeten it,
if he pleases; in fact, live from day to day dependent on his palmyra
alone. Multitudes so live, and it may be safely asserted that this tree
alone furnishes one-fourth the means of sustenance for the population of
the northern provinces.
[Footnote 1: _Borassus flabelliformis_. For an account of the Palmyra,
and its cultivation in the peninsula of Jaffna, see FERGUSON'S monograph
on the _Palmyra Palm of Ceylon_, Colombo, 1850.]
The _Jaggery Palm_[1], the _Kitool_ of the Singhalese, is chiefly
cultivated in the Kandyan hills for the sake of its sap, which is drawn,
boiled down, and crystallised into a coarse brown sugar, in universal
use amongst the inhabitants of the south and west of Ceylon, who also
extract from its pith a farina scarcely inferior to sago. The black
fibre of the leaf is twisted by the Rodiyas into ropes of considerable
smoothness and tenacity. A single Kitool tree has been pointed out at
Ambogammoa, which furnished the support of a Kandyan, his wife, and
their children. A tree has been known to yield one hundred pints of
toddy within twenty-four hours.
[Footnote 1: Caryota urens.]
The _Areca_[1] _Palm_ is the invariable feature of a native garden,
being planted near the wells and water-courses, as it rejoices in
moisture. Of all the tribe it is the most graceful and delicate, rising
to the height of forty or fifty feet[2], without an inequality on its
thin polished stem, which is dark green towards the top, and sustains a
crown of feathery foliage, in the midst of which are clustered the
astringent nuts for whose sake it is carefully tended.
[Footnote 1: A. catechu.]
[Footnote 2: Mr. Ferguson measured an areca at Caltura which was
seventy-five feet high, and grew near a coco-nut which was upwards of
ninety feet. Caltura is, however, remarkable for the growth and
luxuriance of its vegetation.]
The chewing of these nuts with lime and the leaf of the betel-pepper
supplies to the people of Ceylon the same enjoyment which tobacco
affords to the inhabitants of other countries; but its use is, if
possible, more offensive, as the three articles, when combined, colour
the saliva of so deep a red that the lips and teeth appear as if covered
with blood. Yet, in spite of this disgusting accompaniment, men and
women, old and young, from morning till night indulge in the repulsive
luxury.[1]
[Footnote 1: Dr. Elliot, of Colombo, has observed several cases of
cancer in the cheek which, from its peculiar characteristics, he has
designated the "betel-chewer's cancer."]
It is seldom, however, that we find in semi-civilised life habits
universally prevailing which have not their origin, however ultimately
they may be abused by excess, in some sense of utility. The Turk, when
he adds to the oppressive warmth of the sun by enveloping his forehead
in a cumbrous turban, or the Arab, when he increases the sultry heat by
swathing his waist in a showy girdle, may appear to act on no other
calculation than a willingness to sacrifice comfort to a love of
display; but the custom in each instance is the result of precaution--in
the former, because the head requires especial protection from
sun-strokes; and in the latter, from the fact well known to the Greeks
([Greek: eozônoi Achaioi]) that, in a warm climate, danger is to be
apprehended from a sudden chill to that particular region of the
stomach. In like manner, in the chewing of the areca-nut with its
accompaniments of lime and betel, the native of Ceylon is unconsciously
applying a specific corrective to the defective qualities of his daily
food. Never eating flesh meat by any chance, seldom or never using milk,
butter, poultry, or eggs, and tasting fish but occasionally (more rarely
in the interior of the island,) the non-azotised elements abound in
every article he consumes with the exception of the bread-fruit, the
jak, and some varieties of beans. In their indolent and feeble stomachs
these are liable to degenerate into flatulent and acrid products; but,
apparently by instinct, the whole population have adopted a simple
prophylactic. Every Singhalese carries in his waistcloth an ornamented
box of silver or brass, according to his means, enclosing a smaller one
to hold a portion of chunam (lime obtained by the calcination of shells)
whilst the larger contains the nuts of the areca and a few fresh leaves
of the betel-pepper. As inclination or habit impels, he scrapes down the
nut, which abounds in catechu, and, rolling it up with a little of the
lime in a betel-leaf, the whole is chewed, and finally swallowed, after
provoking an extreme salivation. No medical prescription could be more
judiciously compounded to effect the desired object than this practical
combination of antacid, the tonic, and carminative.
The custom is so ancient in Ceylon and in India that the Arabs and
Persians who resorted to Hindustan in the eighth and ninth centuries
carried back the habit to their own country; and Massoudi, the traveller
of Bagdad, who wrote the account of his voyages in A.D. 943, states that
the chewing of betel prevailed along the southern coast of Arabia, and
reached as far as Yemen and Mecca.[1] Ibn Batuta saw the betel plant at
Zahfar A.D. 1332, and describes it accurately as trained like a vine
over a trellis of reeds, or climbing the steins of the coco-nut palm.[2]
[Footnote 1: Massoudi, _Maraudj-al-Dzeheb_, as translated by REINAUD,
_Mémoire_ _sur l'Lede_. p. 230.]
[Footnote 2: _Voyages_, &c. t. ii. p. 205.]
The leaves of the coca[1] supply the Indians of Bolivia and Peru with a
stimulant, whose use is equivalent to that of the betel-pepper among the
natives of Hindustan and the Eastern Archipelago. With an admixture of
lime, they are chewed perseveringly; but, unlike the betel, the colour
imparted by them to the saliva is greenish, instead of red. It is
curious, too, as a coincidence common to the humblest phases of
semi-civilised life, that, in the absence of coined money, the leaves of
the coca form a rude kind of currency in the Andes, as does the betel in
some parts of Ceylon, and tobacco amongst the tribes of the south-west
of Africa.[2]
[Footnote 1: Erythroxylon coca.]
[Footnote 2: Tobacco was a currency in North America when Virginia was
colonised in the early part of the 17th century; debts were contracted
and paid in it, and in every ordinary transaction tobacco answered the
purposes of coin.]
Neither catechu nor its impure equivalent, "terra japonica," is prepared
from the areca in Ceylon; but the nuts are exported in large quantities
to the Maldive Islands and to India, the produce of which they excel
both in astringency and size. The fibrous wood of the areca being at
once straight, firm, and elastic, is employed for making the pingoes
(yokes for the shoulders), by means of which the Singhalese coolie, like
the corresponding class among the ancient Egyptians and the Greeks,
carries his burdens, dividing them into portions of equal weight, one of
which is suspended from each end of the pingo. By a swaying motion
communicated to them as he starts, his own movement is facilitated,
whereas one unaccustomed to the work, by allowing the oscillation to
become irregular, finds it almost impossible to proceed with a load of
any considerable weight.[1]
[Footnote 1: The natives of Tahti use a yoke of the same form as the
Singhalese _pingo_, but made from the wood of the _Hibiscus
tiliaceus._--DARWIN, _Nat. Voy._ ch. xviii. p. 407. For a further
account of the pingo see Vol. I. Part iv. ch. viii. p. 497.]
_Timber trees_, either for export or domestic use, are not found in any
abundance except in the low country, and here the facility of floating
them to the sea, down the streams which intersect the eastern coast of
the island, has given rise to an active trade at Batticaloa and
Trincomalie. But, unfortunately, the indifference of the local officers
entrusted with the issue of licences to fell, and the imperfect control
exercised over the adventurers who embark in these speculations, has led
to a destruction of trees quite disproportionate to the timber obtained,
and utterly incompatible with the conservation of the valuable kinds.
The East India Company have had occasion to deplore the loss of their
teak forests by similar neglect and mismanagement; and it is to be hoped
that, ere too late, the attention of the Ceylon Government may be so
directed to this important subject as to lead to the appointment of
competent foresters, under whose authority and superintendence the
felling of timber may be carried on.
An interesting memoir on the timber trees of Ceylon has been prepared by
a native officer at Colombo, Adrian Mendis, of Morottu,
carpeater-moodliar to the Royal Engineers, in which he has enumerated
upwards of ninety species, which, in various parts of the island, are
employed either as timber or cabinet woods.[1] Of these, the jak, the
Kangtal of Bengal (_Artocarpus integrifolia_), is, next to the coco-nut
and Palmyra, by far the most valuable to the Singhalese; its fruit,
which sometimes attains the weight of 50 lbs., supplying food for their
table, its leaves fodder for their cattle, and its trunk timber for
every conceivable purpose both oeconomic and ornamental. The Jak tree,
as well as the Del, or wild bread-fruit, is indigenous to the forests on
the coast and in the central provinces; but, although the latter is
found in the vicinity of the villages, it does not appear to be an
object of special cultivation. The Jak, on the contrary, is planted near
every house, and forms the shade of every garden. Its wood, at first
yellow, approaches the colour of mahogany after a little exposure to the
air, and resembles it at all times in its grain and marking.
[Footnote 1: Mendis' List will be found appended to the _Ceylon
Calendar_ for 1854.]
The Del (_Artocarpus pubescens_) affords a valuable timber, not only for
architectural purposes, but for ship-building. It and the Halmalille[1]
resembling but larger than the linden tree of England, to which it is
closely allied, are the favourite building woods of the natives, and the
latter is used for carts, casks, and all household purposes, as well as
for the hulls of their boats, from the belief that It resists the attack
of the marine worms, and that some unctuous property in the wood
preserves the iron work from rust.[2]
[Footnote 1: Berry a ammonilla.]
[Footnote 2: The Masula boats, which brave the formidable surf of Madrus
are made of Halmalille, which is there called "Trincomalie wood" from
the place of exportation.]
The Teak (_Tectona grandis_), which is superior to all others, is not a
native of this island, and although largely planted, has not been
altogether successful. But the satin-wood[1], in point of size and
durability, is by far the first of the timber trees of Ceylon. For days
together I have ridden under its magnificent shade. All the forests
around Batticaloa and Trincomalie, and as far north as Jaffna, are
thickly set with this valuable tree. It grows to the height of a hundred
feet, with a rugged grey bark, small white flowers, and polished leaves,
with a somewhat unpleasant odour. Owing to the difficulty of carrying
its heavy beams, the natives only cut it near the banks of the rivers,
down which it is floated to the coast, whence large quantities are
exported to every part of the colony. The richly-coloured and feathery
pieces are used for cabinet-work, and the more ordinary logs for
building purposes, every house in the eastern province being floored and
timbered with satin-wood.
[Footnote 1: Chieroxylon Swietenia.]
Another useful tree, very common in Ceylon, is the Suria[1], with
flowers so like those of a tulip that Europeans know it as the tulip
tree. It loves the sea air and saline soils. It is planted all along the
avenues and streets in the towns near the coast, where it is equally
valued for its shade and the beauty of its yellow flowers, whilst its
tough wood is used for carriage shafts and gun-stocks.
[Footnote 1: Thespesia populnea.]
The forests to the east furnish the only valuable cabinet woods used in
Ceylon, the chief of which is ebony[1], which grows in great abundance
throughout all the flat country to the west of Trincomalie. It is a
different species from the ebony of Mauritius[2], and excels it and all
others in the evenness and intensity of its colour. The centre of the
trunk is the only portion which furnishes the extremely black part which
is the ebony of commerce; but the trees are of such magnitude that
reduced logs of two feet in diameter, and varying from ten to fifteen
feet in length, can readily be procured from the forests at Trincomalie.
[Footnote 1: Diospyros ebenum.]
[Footnote 2: D. reticulata.]
There is another cabinet wood, of extreme beauty, called by the natives
Cadooberia. It is a bastard species of ebony[1], in which the prevailing
black is stained with stripes of rich brown, approaching to yellow and
pink. But its density is inconsiderable, and in durability it is far
inferior to that of true ebony.
[Footnote 1: D. ebenaster.]
The Calamander[1], the most valuable cabinet wood of the island,
resembling rose-wood, but much surpassing it both in beauty and
durability, has at all times been in the greatest repute in Ceylon. It
grows chiefly in the southern provinces, and especially in the forests
at the foot of Adam's Peak; but here it has been so prodigally felled,
first by the Dutch, and afterwards by the English, without any
precautions for planting or production, that it has at last become
exceedingly rare. Wood of a large scantling is hardly procurable at any
price; and it is only in a very few localities, the principal of which
is Saffragam, in the western province, that even small sticks are now to
be found; one reason, assigned for this is that the heart of the tree is
seldom sound, a peculiarity which extends to the Cadooberia.
[Footnote 1: D. hirsuta.]
The twisted portions, and especially the roots of the latter, yield
veneers of unusual beauty, dark wavings and blotches, almost black,
being gracefully disposed over a delicate fawn-coloured ground. Its
density is so great (nearly 60 lbs. to a cubic foot) that it takes an
exquisite polish, and is in every way adapted for the manufacture of
furniture, in the ornamenting of which the native carpenters excel. The
chiefs and headmen, with a full appreciation of its beauty, take
particular pride in possessing specimens of this beautiful wood, roots
of which they regard as most acceptable gifts.
Notwithstanding its value, the tree is nearly eradicated, and runs some
risk of becoming extinct in the island; but, as it is not peculiar to
Ceylon, it may be restored by fresh importations from the south-eastern
coast of India, of which it is equally a native, and I apprehend that
the name, _Calamander_, which was used by the Dutch, is but a corruption
of "Coromandel."
Another species of cabinet wood is produced from the Nedun[1], a large
tree common on the western coast; it belongs to the Pea tribe, and is
allied to the Sisso of India. Its wood, which is lighter than the
"Blackwood" of Bombay, is used for similar purposes.
[Footnote 1: Dalbergia lanceolaria.]
The Tamarind tree[1], and especially its fine roots, produce a
variegated cabinet wood of much beauty, but of such extreme hardness as
scarcely to be workable by any ordinary tool.[2]
[Footnote 1: Tamarindus Indica.]
[Footnote 2: The natives of Western India have a belief that the shade
of the tamarind tree is unhealthy, if not poisonous. But in Ceylon it is
an object of the people, especially in the north of the island, to build
their houses under it, from the conviction that of all trees its _shade
is the coolest_. In this feeling, too, the Europeans are so far disposed
to concur that it has been suggested whether there may not be something
peculiar in the respiration of its leaves. The Singhalese have an idea
that the twigs of the ranna-wara (_Cassia auriculata_) diffuse an
agreeable coolness, and they pull them for the sake of enjoying it by
holding them in their hands or applied to the head. In the south of
Ceylon it is called the Matura tea-tree, its leaves being infused as a
substitute for tea.]
As to fruit trees, it is only on the coast, or near the large villages
and towns, that they are found in any perfection. In the deepest jungle
the sight of a single coco-nut towering above the other foliage is in
Ceylon a never-failing landmark to intimate to a traveller his approach
to a village. The natives have a superstition that the coco-nut will not
grow _out of the sound of the human voice_, and will die if the village
where it had previously thriven become deserted; the solution of the
mystery being in all probability the superior care and manuring which it
receives in such localities.[1] In the generality of the forest hamlets
there are always to be found a few venerable Tamarind trees of
patriarchal proportions, the ubiquitous Jak, with its huge fruits,
weighing from 5 to 50 lbs. (the largest eatable fruit in the world),
each springing from the rugged surface of the bark, and suspended by a
powerful stalk, which attaches it to the trunk of the tree. Lime-trees,
Oranges, and Shaddoks are carefully cultivated in these little gardens,
and occasionally the Rose-apple and the Cachu-nut, the Pappaya, and
invariably as plentiful a supply of Plantains as they find it prudent to
raise without inviting the visits of the wild elephants, with whom they
are especial favourites.
[Footnote 1: See Vol. II. p. 125.]
These, and the Bilimbi and Guava, the latter of which is naturalised in
the jungle around every cottage, are almost the only fruits of the
country; but the Pine-apple, the Mango, the Avocado-pear, the
Custard-apple, the Rambutan (_Nephelium lappaceum_), the Fig, the
Granadilla, and a number of other exotics, are successfully reared in
the gardens of the wealthier inhabitants of the towns and villages; and
within the last few years the peerless Mangustin of Malacca, the
delicacy of which we can imagine to resemble that of perfumed snow, has
been successfully cultivated in the gardens of Caltura and Colombo.
With the exception of the orange, the fruits of Ceylon have one
deficiency, common, I apprehend, to all tropical countries. They are
wanting in that piquancy which in northern climates is attributable to
the exquisite perfection in which the sweet and aromatic flavours are
blended with the acidulous. Either the acid is so ascendant as to be
repulsive to the European palate, or the saccharine so preponderates as
to render Singhalese fruit cloying and distasteful.
Still, all other defects are compensated by the coolness which pervades
them; and, under the exhaustion of a blazing sun, no more exquisite
physical enjoyment can be imagined than the chill and fragrant flesh of
the pine-apple, or the abundant juice of the mango, which, when freshly
pulled, feels as cool as iced water. But the fruit must be eaten
instantly; even an interval of a few minutes after it has been gathered
is sufficient to destroy the charm; for, once severed from the stem, it
rapidly acquires the temperature of the surrounding air.
Sufficient admiration has hardly been bestowed upon the marvellous power
displayed by the vegetable world in adjusting its own temperature,
notwithstanding atmospheric fluctuations,--a faculty in the
manifestation of which it appears to present a counterpart to that
exhibited by animal oeconomy in regulating its heat. So uniform is the
exercise of the latter faculty in man and the higher animals, that there
is barely a difference of three degrees between the warmth of the body
in the utmost endurable vicissitudes of heat and cold; and in vegetables
an equivalent arrangement enables them in winter to keep their
temperature somewhat above that of the surrounding air, and in summer to
reduce it far below it. It would almost seem as if plants possessed a
power of producing cold analogous to that exhibited by animals in
producing heat; and of this beneficent arrangement man enjoys the
benefit in the luxurious coolness of the fruit which nature lavishes on
the tropics.
The peculiar organisation by which this result is obtained is not free
from obscurity, but in all probability the means of adjusting the
temperature of plants is simply dependent on evaporation. As regards the
power possessed by vegetables of generating heat, although it has been
demonstrated to exist, it is in so trifling a degree as to be almost
inappreciable, except at the period of germination, when it probably
arises from the consumption of oxygen in generating the carbonic acid
gas which is then evolved. The faculty of retaining this warmth at night
and at other times may, therefore, be referable mainly to the closing of
the pores, and the consequent check of evaporation.
On the other hand, the faculty of maintaining a temperature below that
of the surrounding air, can only be accounted for by referring it to the
mechanical process of imbibing a continuous supply of fresh moisture
from the soil, the active transpiration of which imparts coolness to
every portion of the tree and its fruit. It requires this combined
operation to produce the desired result; and the extent to which
evaporation can bring down the temperature of the moisture received by
absorption, may be inferred from the fact that Dr. Hooker, when in the
valley of the Ganges, found the fresh milky juice of the Mudar
(_calotropis_) to be but 72°, whilst the damp sand in the bed of the
river where it grew was from 90° to 104°.
Even in temperate climates this phenomenon is calculated to excite
admiration; but it is still more striking to find the like effect rather
increased than diminished in the tropics, where one would suppose that
the juices, especially of a small and delicate plant, before they could
be cooled by evaporation, would be liable to be heated by the blazing
sun.
A difficulty would also seem to present itself in the instance of fruit,
whose juices, having to undergo a chemical change, their circulation
would be conjectured to be slower; and in the instance of those with
hard skins, such as the pomegranate, or with a tough leathery coating,
like the mango, the evaporation might be imagined to be less than in
those of a soft and spongy texture. But all share alike in the general
coolness of the plant, so long as circulation supplies fluid for
evaporation; and the moment this resource is cut off by the separation
of the fruit from the tree, the supply of moisture failing, the process
of refrigeration is arrested, and the charm of agreeable freshness gone.
It only remains to notice the aquatic plants, which are found in greater
profusion in the northern and eastern provinces than in any other
districts of the island, owing to the innumerable tanks and neglected
watercourses which cover the whole surface of this once productive
province, but which now only harbour the alligator, or satisfy the
thirst of the deer and the elephant.
[Footnote 1: See on this subject LINDLEY'S _Introduction to Botany_,
vol. ii. book ii. ch. viii. p. 215.
CARPENTER, _Animal Physiology_, ch. ix. s. 407. CARPENTER'S _Vegetable
Physiology_, ch. xi. s. 407, Lond. 1848.]
The chief ornaments of these neglected sheets of water are the large red
and white Lotus[1], whose flowers may be seen from a great distance
reposing on their broad green leaves. In China and some parts of India
the black seeds of these plants, which are not unlike little acorns in
shape, are served at table in place of almonds, which they are said to
resemble, but with a superior delicacy of flavour. At some of the tanks
where the lotus grows in profusion in Ceylon, I tasted the seeds
enclosed in the torus of the flowers, and found them white and
delicately-flavoured, not unlike the small kernel of the pine cone of
the Apennines. This red lotus of the island appears to be the one that
Herodotus describes as abounding in the Nile in his time, but which is
now extinct; with a flower resembling a rose, and a fruit in shape like
a wasp's nest, and containing seeds of the size of an olive stone, and
of an agreeable flavour.[2] But it has clearly no identity with those
which he describes as the food of the Lotophagi of Africa, of the size
of the mastic[3], sweet as a date, and capable of being made into wine.
[Footnote 1: Nelumbium speciosum.]
[Footnote 2: Herodotus, b. ii. s. 92.]
[Footnote 3: The words are "[Greek: Esti megathos hoson te tês schinou]"
(Herod. b. iv. s. 177); and as [Greek: schinos] means also a _squill_ or
a _sea-onion_, the fruit above referred to, as the food of the
Lotophagi, must have been of infinitely larger size and in every way
different from the lotus of the Nile, described in the 2nd book, as well
as from the lotus in the East. Lindley records the conjecture that the
article referred to by Herodotus was the _nabk_, the berry of the
lote-bush (_Zizyphus lotus_), which the Arabs of Barbary still eat.
(_Vegetable Kingdom_, p. 582.)]
One species of the water lily, the _Nymphæa rubra_, with small red
flowers, and of great beauty, is common in the ponds near Jaffna and in
the Wanny; and I found in the fosse, near the fort of Moeletivoe, the
beautiful blue lotus, _N. stellata_, with lilac petals, approaching to
purple in the centre, which had not previously been supposed to be a
native of the island.
Another very interesting aquatic plant, which was discovered by Dr.
Gardner in the tanks north of Trincomalie, is the _Desmanthus natans_,
with highly sensitive leaves floating on the surface of the water. It is
borne aloft by masses of a spongy cellular substance, which occur at
intervals along its stem and branches, but the roots never touch the
bottom, absorbing nourishment whilst floating at liberty, and only found
in contact with the ground after the subsidence of water in the
tanks.[1]
[Footnote 1: A species of _Utricularia_, with yellow flowers (U.
stellaris), is a common water-plant in the still lakes near the fort of
Colombo, where an opportunity is afforded of observing the extraordinary
provision of nature for its reproduction. There are small appendages
attached to the roots, which become distended with air, and thus carry
the plant aloft to the surface, during the cool season. Here it floats
till the operation of flowering is over, when the vesicles burst, and by
its own weight it returns to the bottom of the lake to ripen its seeds
and deposit them in the soil; after which the air vessels again fill,
and again it re-ascends to undergo the same process of fecundation.]
