Locust tree

From Wikipedia, the free encyclopedia

Locust tree can mean:

  • Any of a number of tree species in the genera Gleditsia or Robinia, including:
    • Honey locust (Gleditsia triacanthos), a leguminous tree with pods having a sweet, edible pulp
    • Black locust (Robinia pseudoacacia), a leguminous tree with toxic pods
    • Water locust (Gleditsia aquatica), a leguminous tree with one seed per pod
  • Or less commonly, "African locust bean tree" (Parkia biglobosa), which is also known as néré
  • Also not commonly, the carob tree, Ceratonia siliqua, whose pods are called locust beans.



"Locust" comes from the Latin locusta, meaning both "locust" (the insect) and "lobster". By analogy with a levantine use of the Greek word for the insect, akris, for the pods of the carob tree which supposedly resembled it, the pod-bearing North American tree was called "locust" starting in the 1630s.[1]
