branches, when they meet with any obstruction in their
descent conform themselves to the shape of the resisting
body, and thus occasion many curious metamorphoses.
I recollect seeing them stand in the perfect shape
of a gate long after the original posts and cross
piece had decayed and disappeared; and I have been
told of their lining the internal circumference of
a large bricked well, like the worm in a distiller’s
tub; there exhibiting the view of a tree turned inside
out, the branches pointing to the centre, instead
of growing from it. It is not more extraordinary
in its manner of growth than whimsical and fantastic
in its choice of situations. From the side of
a wall or the top of a house it seems to spring spontaneously.
Even from the smooth surface of a wooden pillar, turned
and painted, I have seen it shoot forth, as if the
vegetative juices of the seasoned timber had renewed
their circulation and begun to produce leaves afresh.
I have seen it flourish in the centre of a hollow
tree of a very different species, which however still
retained its verdure, its branches encompassing those
of the adventitious plant whilst its decayed trunk
enclosed the stem, which was visible, at interstices,
from nearly the level of the plain on which they grew.
This in truth appeared so striking a curiosity that
I have often repaired to the spot to contemplate the
singularity of it. How the seed from which it
is produced happens to occupy stations seemingly so
unnatural is not easily determined. Some have
imagined the berries carried thither by the wind,
and others, with more appearance of truth, by the birds;
which, cleansing their bills where they light, or
attempt to light, leave, in those places, the seeds
adhering by the viscous matter which surrounds them.
However this be, the jawi-jawi, growing on buildings
without earth or water, and deriving from the genial
atmosphere its principle of nourishment, proves in
its increasing growth highly destructive to the fabric
where it is harboured; for the fibrous roots, which
are at first extremely fine, penetrate common cements,
and, overcoming as their size enlarges the most powerful
resistance, split, with the force of the mechanic
wedge, the most substantial brickwork. When the
consistence is such as not to admit the insinuation
of the fibres the root extends itself along the outside,
and to an extraordinary length, bearing not unfrequently
to the stem the proportion of eight to one when young.
I have measured the former sixty inches, when the
latter, to the extremity of the leaf, which took up
a third part, was no more than eight inches. I
have also seen it wave its boughs at the apparent height
of two hundred feet, of which the roots, if we may
term them such, occupied at least one hundred; forming
by their close combination the appearance of a venerable
gothic pillar. It stood near the plains of Krakap,
but, like other monuments of antiquity, it had its
period of existence, and is now no more.
