Daniel Wildenstein's French Oaks (Fr-I) winner Aqarelliste remained undefeated Sunday by winning the Prix Vermeille Hermitage Barriere (Fr-I) by a short neck over Diamilina at Longchamp. On good turf at the French course, Aquarelliste completed the 1 1/2 miles in 2:29 2/5 under jockey Dominique Boeuf.Mare Nostrum finished third, 2 1/2 lengths behind Diamilina, with Mot Juste fourth in the field of 12 3-year-old fillies.Aquarelliste has now won all four of her starts, including a 1 1/2-length victory in the Prix de Diane Hermes-French Oaks in her most recent start prior to Sunday. The daughter of Danehill made her racing debut at Longchamp in late April. Elie Lellouche began training Aquarelliste following her maiden victory as Wildenstein removed his horses from trainer Andre Fabre. Aquarelliste -- out of Agathe, by Manila -- was bred in France by Allez France Stable."I think that she might be the new Allez France we have been waiting for so long," Alec Wildenstein, the owner's son, told the French Racing and Breeding Commmitee. "She will run in the Arc and, in my opinion, she will win the Arc.""She has run three times for me and won three times. I am proud of her," said Lellouche. "She has talent and was probably not yet at her best for this race, slightly rusty. She is quite lazy in the morning and this race will do her a lot of good. We only have to cross our fingers now and hope that she will be at her best for the Arc."The last female to win the Arc was Urban Sea -- dam of Galileo -- in 1993.
