Locust tree can mean:

• Any of a number of tree species in the generaGleditsia orRobinia, 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
• Less commonly, "African locust bean tree" (Parkia biglobosa), which is also known as néré
• Also not commonly, thecarob tree,Ceratonia siliqua, whose pods are calledlocust beans

"Locust" comes from theLatinlocusta, meaning both "locust" (the insect) and "lobster". By analogy with aLevantine use of theGreek word for the insect,akris, for the pods of the carob tree, which supposedly resembled it, the pod-bearing North American tree started to be called "locust" in the 1630s.^[1]
