Narrative

Type = Hybrid. Flower = Male. Per Remaily (see citation): "These importations are spontaneous vines gathered from the Pyrenees in south-western France, and were interpretated and selected as the autochthonous form of Vitis vinifera of Europe. The grave concern caused by the decreasing number of this wild-growing form of Vitis has awakened the portended action - needed to warn and prevent their probable extinction. IN the last hundred years of imperious pressures from 'imported' diseases and pests, the great expansions of thousands of these autochthonic vines, have dwindled to a condition of declining endangement. With the importation to Europ of North American species of Vitis at an ever increasing establishment of rootstocks during and after the disasterous period of viticultural decline, owing to the scourge of Oidium and the devastation of Phylloxera; these exotic species from the North American Continent have spontaneously hybridized with both the European autochthon, V. vinifera, sylvestris and the cultivated grape, v. vinifera, sativa, de Candolle. The adventitious naturalization of these wild-growing stands with increased resistance to various diseases and pests have become successfully competitive and long-lived, and are now permanent members of the natural flora of Europe. It is imperative for future systematic studies that the two Vitis vinifera forms: sativa, de Candolle and sylvestris, Omelein be clearly characterized, and both, from the wide-spread diversity of interspecific feral vines that have spontaneously evolved along with the development and culture of interspecific root-stocks and interspecific direct-producers. Both the European autochthon and the the native North American species are characterized by dioecism, however this 'mode' has been allowed too much weight in confirming identification, and is tenuously inconclusive."
