The US and Mexico signed the Treaty of Limits on January 12, 1828, a few decades before the Mexican-American War. As Mexican historians will attest, given that the US subsequently stole about a third of the Republic of Mexico, the name of the treaty was … well … very ironic. The treaty was signed by Joel Poinsett, first US Minister to Mexico. Poinsett was a botanist and physician, as well as a politician. He named the beautiful plant, Euphorbia pulcherrima, which is indigenous to Mexico and Central America, after himself, in an embarrassing act of white male entitlement. In Nahuatl, the language of the Aztecs, the plant is named Cuetlaxochitl, meaning “flower that grows in residues or soil. You may know the flowering plant that is a traditional Christmas ornament as the Poinsettia.
