Vitis riparia Michx., Fl. Bor. - Amer., 2: 231. 1803.

Neophyte doubtfully present in Sicily.

Notes. Literature data regarding the presence of V. riparia in Sicily ( Conti et al., 2005; Celesti-Grapow et al., 2009, 2010; �rdenghi et al., 2014) may actually refer to either V. × instabilis (especially to the riparia -like cultivar ‘101-14 Mgt’) or V. × koberi , both morphologically reminiscent of V. riparia . The species was not recorded during our field surveys. Employed mainly during the early stag- es of the phylloxera invasion, it appears to be less common than thought in the past: many previous Italian literature data have recently been referred to its hybrids (see Ardenghi et al., 2014) and its occurrence seems mostly limited to riverine habitats.
