    Summary Author: Dale Hugo

    Shown above is a honey locust tree ( Gleditsia triacanthos), that I
    photographed this past September in Arlington Height, Illinois.
    Sometimes referred to as the thorny locust, this deciduous tree in the
    family Fabaceae, is indigenous to central North America. It’s often
    found in the moist soil of river valleys. In the Mid-West and central
    plains of the U.S. they were on occasion planted as windbreaks to
    help stabilize soil.

    The thorns of the honey locust are fierce (bottom photo). They tend to
    grow in pairs along the tree’s lower branches and trunk. It’s thought
    that the long, sharp thorns evolved to protect the tree from the
    grazing megafauna that flourished during the last ice age.
