          autumn; yield a hard wood and edible nuts in a prickly
          bur [syn: chestnut]

 Chestnut tree
    (Heb. _'armon_; i.e., "naked"), mentioned in connection with
    Jacob's artifice regarding the cattle (Gen. 30:37). It is one of
    the trees of which, because of its strength and beauty, the
    Assyrian empire is likened (Ezek. 31:8; R.V., "plane trees"). It
    is probably the Oriental plane tree (Platanus orientalis) that
    is intended. It is a characteristic of this tree that it
    annually sheds its outer bark, becomes "naked." The chestnut
    tree proper is not a native of Palestine.
