The vine grows wild in the temperate regions of Western Asia, Southern Europe, Algeria, and Marocco.[933] It is especially in the Pontus, in Armenia, to the south of the Caucasus and of the Caspian Sea, that it grows with the luxuriant wildness of a tropical creeper, clinging to tall trees and producing abundant fruit without pruning or cultivation. Its vigorous growth is mentioned in ancient Bactriana, Cabul, Kashmir, and even in Badakkhan to the north of the Hindu Koosh.[934] Of course, it is a question whether the plants found there, as elsewhere, are not sprung from seeds carried from vineyards by birds. I notice, however, that the most trustworthy botanists, those who have most thoroughly explored the Transcaucasian provinces of Russia, do not hesitate to say that the plant is wild and indigenous in this region. It is as we advance towards India and Arabia, Europe and the north of Africa, that we frequently find in floras the expression that the vine is “subspontaneous,” perhaps wild, or become wild (verwildert is the expressive German term).
The dissemination by birds must have begun very early, as soon as the fruit existed, before cultivation, before the migration of the most ancient Asiatic peoples, perhaps before the existence of man in Europe or even in Asia. Nevertheless, the frequency of cultivation, and the multitude of forms of the cultivated grape, may have extended naturalization and introduced among wild vines varieties which originated in cultivation. In fact, natural agents, such as birds, winds, and currents, have always widened the area of species, independently of man, as far as the limits imposed in each age by geographical and physical conditions, together with the hostile action of other plants and animals, allow. An absolutely primitive habitation is more or less mythical, but habitations successively extended or restricted are in accordance with the nature of things. They constitute areas more or less ancient and real, provided that the species has maintained itself wild without the constant addition of fresh seed.
Concerning the vine, we have proofs of its great antiquity in Europe as in Asia. Seeds of the grape have been found in the lake-dwellings of Castione, near Parma, which date from the age of bronze,[935] in a prehistoric settlement of Lake Varese,[936] and in the lake-dwellings of Wangen, Switzerland, but in the latter instance at an uncertain depth.[937] And, what is more, vine-leaves have been found in the tufa round Montpellier, where they were probably deposited before the historical epoch, and in the tufa of Meyrargue in Provence, which is certainly prehistoric,[938] though later than the tertiary epoch of geologists.[939]
A Russian botanist, Kolenati,[940] has made some very interesting observations on the different varieties of the vine, both wild and cultivated, in the country which may be called the central, and perhaps the most ancient home of the species, the south of the Caucasus. I consider his opinion the more important that the author has based his classification of varieties with reference to the downy character and veining of the leaves, points absolutely indifferent to cultivators, and which consequently must far better represent the natural conditions of the plant. He says that the wild vines, of which he had seen an immense quantity between the Black and Caspian Seas, may be grouped into two subspecies which he describes, and declares are recognizable at a distance, and which are the point of departure of cultivated vines, at least in Armenia and the neighbourhood. He recognized them near Mount Ararat, at an altitude where the vine is not cultivated, where, indeed, it could not be cultivated. Other characters—for instance, the shape and colour of the grapes—vary in each of the subspecies. We cannot enter here into the purely botanical details of Kolenati’s paper, any more than into those of Regel’s more recent work on the genus Vitis;[941] but it is well to note that a species cultivated from a very remote epoch, and which has perhaps two thousand described varieties, presents in the district where it is most ancient, and probably presented before all cultivation, at least two principal forms, with others of minor importance. If the wild vines of Persia and Kashmir, of Lebanon and Greece, were observed with the same care, perhaps other sub-species of prehistoric antiquity might be found. The idea of collecting the juice of the grape and of allowing it to ferment may have occurred to different peoples, principally in Western Asia, where the vine abounds and thrives. Adolphe Pictet,[942] who has, in common with numerous authors, but in a more scientific manner, considered the historical, philological, and even mythological questions relating to the vine among ancient peoples, admits that both Semitic and Aryan nations knew the use of wine, so that they may have introduced it into all the countries into which they migrated, into India and Egypt and Europe. This they were the better able to do, since they found the vine wild in several of these regions.
The records of the cultivation of the grape and of the making of wine in Egypt go back five or six thousand years.[943] In the West the propagation of its culture by the Phœnicians, Greeks, and Romans is pretty well known, but to the east of Asia it took place at a late period. The Chinese who now cultivate the vine in their northern provinces did not possess it earlier than the year 122 B.C.[944]
It is known that several wild vines exist in the north of China, but I cannot agree with M. Regel in considering Vitis Amurensis, Ruprecht, the one most analogous to our vine, as identical in species. The seeds drawn in the Gartenflora, 1861, pl. 33, differ too widely. If the fruit of these vines of Eastern Asia had any value, the Chinese would certainly have turned them to account.
Common Jujube—Zizyphus vulgaris, Lamarck.
According to Pliny,[945] the jujube tree was brought from Syria to Rome by the consul Sextus Papinius, towards the end of the reign of Augustus. Botanists, however, have observed that the species is common in rocky places in Italy,[946] and that, moreover, it has not yet been found wild in Syria, although it is cultivated there, as in the whole region extending from the Mediterranean to China and Japan.[947]
The result of the search for the origin of the jujube tree as a wild plant bears out Pliny’s assertion, in spite of the objections I have just mentioned. According to plant collectors and authors of floras, the species appears to be more wild and more anciently cultivated in the east than in the west of its present wide area. Thus, in the north of China, de Bunge says it is “very common and very troublesome (on account of its thorns) in mountainous places.” He had seen the thornless variety in gardens. Bretschneider[948] mentions the jujube as one of the fruits most prized by the Chinese, who give it the simple name tsao. He also mentions the two varieties, with and without thorns, the former wild.[949] The species does not grow in the south of China and in India proper, because of the heat and moisture of the climate. It is found again wild in the Punjab, in Persia, and Armenia.
Brandis[950] gives seven different names for the jujube tree (or for its varieties) in modern Indian languages, but no Sanskrit name is known. The species was therefore probably introduced into India from China, at no very distant epoch, and it must have escaped from cultivation and have become wild in the dry provinces of the west. The Persian name is anob, the Arabic unab. No Hebrew name is known, a further sign that the species is not very ancient in the west of Asia,
