This paper summarizes the occurrence of the European wild vine - Vitis vini
fera L. ssp. silvestris (Gmelin) Hegi - from bibliography and observations
made in the framework of research on its ecology in the alluvial and colluv
ial forests of Europe. The state of the wild vine is disquieting within mos
t of the European countries; in some countries we noticed a lack of recent
reliable data. The subspecies silvestris can principally be distinguished f
rom cultivated grapevine by its dioicity. Morphological vegetative criteria
are very variable; in particular, we demonstrate that sexual dimorphism oc
curs in Austrian populations, while it is not found in those of the Basque
countries.
