'''Osage-orange''', '''Horse-apple''', '''Bois D'Arc''', or '''Bodark''' ('''''Maclura pomifera''''') is a small [[deciduous]] [[tree]] or large [[shrub]], typically growing to {{convert|8|-|15|m|ft}} tall. It is [[Plant sexuality|dioeceous]], with male and female [[flower]]s on different plants. The [[fruit]], a [[multiple fruit]], is roughly spherical, but bumpy, and 7–15 cm in diameter, and it is filled with a sticky white [[latex]] [[sap]]. In fall, its color turns a bright yellow-green and it has a faint odor similar to that of [[orange (fruit)|oranges]].<ref>Mabberley, D.J. 1987. ''The Plant Book. A portable dictionary of the higher plants''. [[Cambridge University Press]], Cambridge. 706 p. ISBN 0-521-34060-8.</ref> ''Maclura'' is closely related to the genus ''[[Cudrania]]'', and hybrids between the two genera have been produced. In fact, some botanists recognize a more broadly defined ''Maclura'' that includes species previously included in ''Cudrania'' and other genera of Moraceae. The trees range from {{convert|40|-|60|ft|m}} high with short trunk and round-topped head. The juice is milky and acrid. The roots are thick, fleshy, covered with bright orange bark. The leaves are arranged alternately on a slender growing shoot {{convert|3|-|4|ft|m}} long, varying from dark to pale tender green. In form they are very simple, a long oval terminating in a slender point. In the axil of every growing leaf is found a growing spine which when mature is about {{convert|1|in|cm}} long, and rather formidable. The pistillate and staminate flowers are on different trees; both are inconspicuous; but the fruit is very much in evidence. This in size and general appearance resembles a large, yellow green orange; only its surface is roughened and tuberculated. It is, in fact, a compound fruit such as botanists call a [[syncarp]], where the [[carpel]]s (that is, the ovaries) have grown together and that the great orange-like ball is not one fruit but many. It is heavily charged with milky juice which oozes out at the slightest wounding of the surface. Although the flowering is diœcious, the pistillate tree even when isolated will bear large oranges, perfect to the sight but lacking the seeds. *Bark: Dark, deeply furrowed, scaly. Branchlets at first bright green, pubescent, during first winter they become light brown tinged with orange, later they become a paler orange brown. Branches with yellow pith, and armed with stout, straight, axillary spines. *Wood: Bright orange yellow, sapwood paler yellow; heavy, hard, strong, flexible, capable of receiving a fine polish, very durable in contact with the ground. It has a specific gravity of 0.7736 and {{convert|1|ft3|m3}} of the wood has a weight of {{convert|48.21|lb|abbr=on}}. *Winter buds: All buds lateral. Depressed-globular, partly immersed in the bark, pale chestnut brown. *Leaves: Alternate, simple, {{convert|3|-|5|in|cm}} long, {{convert|2|-|3|in|cm}} wide, ovate to oblong-lanceolate, entire, acuminate, or acute or cuspidate, rounded, wedge-shaped or subcordate at base. Feather-veined, midrib prominent. They come out of the bud involute, pale bright green, pubescent and tomentose, when full grown are thick, firm, dark green, shining above, paler green below. In autumn they turn a clear bright yellow. Petioles slender, pubescent, slightly grooved. Stipules small, caducous. *Flowers: June, when leaves are full grown; diœcious. Staminate flowers in racemes, borne on long, slender, drooping peduncles developed from the axils of crowded leaves on the spur-like branchlets of the previous year. Racemes are short or long. Flowers pale green, small. Calyx hairy, four-lobed. Stamens four, inserted opposite lobes of calyx, on the margin of thin disk; filaments flattened, exserted; anthers oblong, introrse, two-celled; cells opening longitudinally; ovary wanting. Pistillate flowers borne in a dense globose many-flowered head which appears on a short stout peduncle, axillary on shoots of the year. Calyx, hairy, four-lobed; lobes thick, concave, investing the ovary, and inclosing the fruit. Ovary superior, ovate, compressed, green, crowned by a long slender style covered with white stigmatic hairs. Ovule solitary. *Fruit: Pale green globe, {{convert|4|-|5|in|cm}} in diameter, made up of numerous small [[drupe]]s, crowded and grown together. These small drupes are oblong, compressed, rounded, often notched at the apex. They are filled with milky, latex-based juice. The seeds are oblong. The fruit is often seedless, and floats.<ref name=Keeler>{{cite book | last =Keeler | first =Harriet L. | title =Our Native Trees and How to Identify Them | publisher =Charles Scriber's Sons | date =1900 | location =New York | pages =186–189 }}</ref> {{Inc| Maclura pomifera, Schneid.

It needs severe pruning to keep it in bounds and the shoots of a single year will grow {{convert|3|-|6|ft|m}} long. A neglected hedge will soon become fruit-bearing.
