Definitions

3. A species of tree known for its compound leaves and clusters of fragrant white blossoms, commonly found in temperate regions

Etymology: The black locust tree, native to the southeastern United States and widely planted elsewhere, carries a Latin name that is itself a kind of mistake. "Pseudoacacia" is built from Greek "pseudes", meaning false, and "acacia", the name of a different genus of trees. The black locust is a member of the pea family, not the acacia group, but Carl Linnaeus placed it in a genus that resembled the acacias in its leaves and flowers, and the name was coined to flag that resemblance as only apparent. The word therefore records a botanical judgment rather than a folk story. Its first part marks the tree as a false acacia, a warning to gardeners and botanists that the feathery foliage and clusters of white, fragrant blossoms look like those of the true acacias while the plants are unrelated. The tree's common English name, locust, reflects an entirely different and older mistake, since early European settlers applied the name of a biblical insect to this tree, but "pseudoacacia" preserves the classification logic instead.
