Vitis silvestrii
Vitis silvestrii is a species of polygamo-dioecious plant in the grape family native to the forested slopes of western Hubei and southern Shaanxi in China from 300 to 1200 meters above sea level. Its flowers appear in May, males having abortive pistils
Vitis silvestrii should not be confused with the very similarly named V. sylvestris Bartram, which some botanists and taxonomists believe to be synonymous with V. vinifera ssp. silvestris, the dioecious, ancestral form of V. vinifera. The name silvestrii was chosen to honor the Reverend, or Père, C. Silvestri, an Italian collector of plants specializing in phanerogams, and the collector of this species.
