[Wikipedia] History: The earliest account of the tree in the English language was given by William Dunbar, a Scottish explorer, in his narrative of a journey made in 1804 from St. Catherine's Landing on the Mississippi River to the Ouachita River.[14] Meriwether Lewis sent some slips and cuttings of the curiosity to President Jefferson in March 1804. According to Lewis's letter, the samples were donated by "Mr. Peter Choteau, who resided the greater portion of his time for many years with the Osage Nation". Those cuttings did not survive.
