[Wikipedia] Etymology: The genus name Parkinsonia honors the English botanist John Parkinson (1567–1650), while the species Latin name aculeata refers to the thorny stem of this plant.
The name "Jerusalem thorn" stems from a mistranslation of the Spanish/Portuguese word girasol ('turning toward the sun'). (link added by Mary Ann Machi)
