Captain Meriwether Lewis sent President Thomas Jefferson some slips of Osage Orange (then called Osage Apple) in March 1804 from St. Louis. Pierre Chouteau had introduced it to Lewis from an Osage Indian village west of St. Louis. The Indians used the wood to make bows and it was also known as Bow Wood. The plant was named for William Maclure, an early American geologist.
