Thanks for the photo & info, Paul_S.

Wikipedia says that Alexander the Great introduced this "Persian nut" from Iran & Central Asia to Macedonian & Greek in the 4th century BC. And that English colonists brought it to the Americas in the 17th century. So the walnut tree, under which Washington first took command of the American Army in 1775, was still relatively new "novelty item" at the time.
