PLANE TREE (עֶרְמוֹן, H6895). The Heb. word ’armôn could be tr. “plane tree,” but actually in the KJV it occurs as CHESTNUT (
If it is a plane then it is the Eastern plane, Plantanus orientalis, normally called the Oriental plane. This plane grows in Pal. and Mount Lebanon. It bears flowers in clusters of rounded balls on a common stalk. The leaves are large and resemble those of the sycamore. This tree was held sacred in the E, and was very much valued for its shade by the Greeks.
