Naturalized English oak is not so common in our area. We have spotted it only a couple of times, always in coastal situations. Its acorns are on long pedicels. White oak ( Q. alba ), which may be confused with English oak, has sessile acorns. In Massachusetts, the only other species that has acorns on long pedicels is swamp white oak ( Q. bicolor ).
