Hura is a genus of trees in the family Euphorbiaceae described by Carl Linnaeus in 1753.

[1][2] It is native to South America, Mesoamerica, and the West Indies.

[3][4][5][6][7] In 1783, Johann Gerhard König used the name Hura to refer to a very different plant from the one Linnaeus had named.

Thus was created an illegitimate homonym.

[8][9] Under the rules of nomenclature, Koenig's name had to be abandoned.
