CHAP. 62. (34.)—THE IVY-TWENTY VARIETIES OF IT.
It is said that the ivy now grows in Asia,
1 though Theophrastus
2 has denied that such is the fact, and asserts that it
grows nowhere in India, except upon Mount Meros.
3 He says,
too, that Harpalus used every possible exertion to naturalize
it in Media, but to no purpose; and that Alexander, in consequence of the rarity of this plant, had himself crowned
4
with it, after the example of Father Liber, when returning
victorious with his army from India: and at the present day
even, it is used to decorate the thyrsus of that god, and the
casques and bucklers employed by the nations of Thrace in
their sacred ceremonials. The ivy is injurious
5 to all trees
and plants, and makes its way through tombs and walls; it
forms a haunt much frequented by serpents, for its refreshing
coolness; so that it is a matter for astonishment that there
should have been such remarkable veneration for this plant.
The two principal kinds in the ivy, as in other plants, are
the male tree and the female.
6 The male is said to have a
larger trunk than the female, and a leaf that is harder and
more unctuous, with a flower nearly approaching to purple:
indeed, the flower of both the male and female tree strongly
resembles the wild
7-rose, were it not destitute of smell. Each
of these kinds of ivy is divided into three other varieties:
the white
8 ivy, the black,
9 and a third known as the helix."
10
These varieties are again subdivided into others, as there is
one in which the fruit only is white, and another in which it
is only the leaf that is so. In those which have a white fruit,
the berry in some cases is closely packed and large, the clusters,
which are known as "corymbi," being of a spherical form.
So, too, with the selenitium, which has a smaller berry, and
fewer clusters; and the same is the case with the black ivy.
One kind has a black seed, and another a seed of a saffron
11
colour—it is this last that poets use for their chaplets,
12 and
the leaves of it are not so black as in the other kinds: by some
it is known as the ivy of Nysa, by others as that of Bacchus:
13
it is the one that among the black varieties has the largest
clusters of all. Some of the Greek writers even distinguish
in this last kind two varieties, according to the colour of the
berries, the erythranum
14 and the chrysocarpus.
15
It is the helix, however, that has the most peculiarities of
all, and in the appearance of the leaf more particularly, which
is small, angular, and of a more elegant shape, the leaf in all
the other kinds being plain and simple. It differs, too, in the
distance between the joints, and in being barren more especially, as it never bears fruit. Some authors, however, think
that this difference exists solely in respect of age and not of
kind, and are of opinion that what is the helix when young,
becomes the ordinary ivy when old. This, however, is clearly
proved to be an error upon their part, for we find more varieties
of the helix than one, and three in particular—that of a grass-green colour, which is the most abundant of all, the kind with
a white leaf, and a third, which is parti-coloured, and known
as the Thracian helix. In that of a grass-green colour, the
leaves are smaller, more closely packed together, and symmetrically arranged; while in the other kinds the features are altogether different. In the parti-coloured kind, also, one variety
has a smaller leaf than usual, similarly arranged, and lying
closer together, while in the other none of these features are
observed. The leaves, too, are either greater or smaller and
differ in the disposition of the spots upon them, and in the
white helix some of them are whiter than others: the grass-green variety, however, is the one that grows to the greatest
height.
The white helix is in the habit of killing trees by depriving
them of their juices, and increases to such a degree of density
as to be quite a tree itself. Its characteristics are, a very
large, broad, leaf, and projecting buds, which in all the other
kinds are bent inwards; its clusters, too, stand out erect.
Although, too, all the ivies have arms that throw out a root,
those of this variety are particularly branchy and strong; next
to it in strength, are those of the black ivy.
It is a peculiarity of the white ivy to throw out arms from
the middle of the leaves, with which it invariably embraces any
object that may be on either side of it; this is the case, too,
with walls, even though it should not be able to clasp them.
If the trunk is cut across in ever so many places, it will still
live and thrive, having as many fresh roots as it has arms, by
means of which it ensures safety and impunity, while at the
same time it sucks and strangles the trees to which it clings.
There are great differences also in the fruit of both the white
ivy and the black; for in some of them the berry is so bitter
that birds will not touch it. There. is an ivy also which grows
upright,
16 and stands without any support; being the only
one that does so among all the varieties, it has thence obtained the distinctive name of "cissos." The chamæcissos,
17
on the other hand, is never found except creeping upon the
ground.
