Note 941 — Chapter IV

Regel, Acta Horti Imp. Petrop., 1873. In this short review of the genus, M. Regel gives it as his opinion that Vitis vinifera is a hybrid between two wild species, V. vulpina and V. labrusca, modified by cultivation; but he gives no proof, and his characters of the two wild species are altogether unsatisfactory. It is much to be desired that the wild and cultivated vines of Europe and Asia should be compared with regard to their seeds, which furnish excellent distinctions, according to Englemann’s observations on the American vines.
