I second opinion of Neil,on account of shape of fruits.
Ischia Black from UCD has a neck,while ,Vladis fruits are totally round.
However ,i will not argue that Vladis ,fig is not Ischia Black,because I have seen other fig trees making different shape fruits in different climates,sometimes ,being caprified ,makes the fruit become a different shape or color(interior-exterior) compared to ,non caprified,however,I also notice ,there is a substantial difference in shape ,in the 2 specimen discussed here.
