Premise: The Newtown Pippin, also known as Albemarle Pippin, is an American apple originated in the late 17th or early 18th century and still cultivated on a small scale. At one time there were two very similar apple cultivars known as the 'Yellow Newtown' ('Albermarle Pippin') and 'Green Newtown' ('Brooke Pippin'), one of which perhaps originated as a sport of the other.
Hypothesis: Albermarle Pippin is an Italian apple.
