| Habitat notes | In the wild, all species of Vitis are normally dioecious, but under domestication, variants with perfect flowers appear to have been selected. Most Vitis species are found in the temperate regions of the Northern Hemisphere in North America and Asia with a few in the tropics. However they are sufficiently closely related to allow easy interbreeding and the resultant interspecific hybrids are invariably fertile and vigorous. Thus the concept of a species is less well defined and more likely represents the identification of different ecotypes of Vitis that have evolved in distinct geographical and environmental circumstances. Found growing on the slopes of the crater lake Rano Kao, Rapa Nui (Easter Island) as well as in the fossil record of KAO3. (Gossen,2010) |
