Maclura pomifera

Maclura pomifera, commonly known as the Osage orange, is a small deciduous tree or large shrub, typically growing to 8 to 15 metres (30–50 ft) tall. The distinctive fruit, from a multiple fruit family, is roughly spherical, bumpy, 8 to 15 centimetres (3–6 in) in diameter, and turns a bright yellow-green in the fall. The fruits exude a sticky white latex when cut or damaged. Despite the name "Osage orange", it is only very distantly related to the orange, and is instead a member of the mulberry family, Moraceae.

M. pomifera has been known by a variety of common names in addition to Osage orange, including hedge apple, horse apple, bois d'arc, bodark, bow-wood, yellow-wood, mock orange and monkey ball.

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. It was a curiosity when Meriwether Lewis sent some slips and cuttings 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 didn't survive, but later the thorny Osage orange tree was widely naturalized throughout the United States. In 1810, Bradbury relates that he found two trees growing in the garden of Pierre Chouteau, one of the first settlers of St. Louis, apparently the same person.
