Etymology
The name derives from the Greek παρθένος (parthenos) "virgin", and κισσός (kissós) (Latinized as "cissus"), "ivy". The reason is variously given as the ability of these creepers to form seeds without pollination[4] or the English name of P. quinquefolia, Virginia creeper, which has become attached to the whole genus.[5]
Fossil record
Among the middle Miocene Sarmatian palynoflora from the Lavanttal Basin, Austrian researchers have recognized Parthenocissus fossil pollen. The sediment containing the Parthenocissus fossil pollen had accumulated in a lowland wetland environment with various vegetation units of mixed evergreen/deciduous broadleaved/conifer forests surrounding the wetland basin. Key relatives of the fossil taxa found with Parthenocissus are presently confined to humid warm temperate environments, suggesting a subtropical climate during the middle Miocene in Austria.[6]
Food plants
Parthenocissus species are used as food plants by the larvae of some Lepidoptera species including the brown-tail, Gothic, and the Virginia creeper sphinx.
