Plane Tree plan'-tre ('armon; platanos (Genesis 30:37), elate ("pine" or "fir") (Ezekiel 31:8); the King James Version chestnut): `Armon is supposed to be derived from the root aram, meaning "to be bare" or "naked"; this is considered a suitable term for the plane, which sheds its bark annually. The chestnut of the King James Version is not an indigenous tree, but the plane (Planus orientalis) is one of the finest trees in Palestine, flourishing especially by water courses (compare Ecclesiastes 24:14).
