Zanthoxylum fagara

Zanthoxylum fagara or wild lime, is a species of flowering plant that—despite its name—is not part of the genus Citrus with real limes and other fruit, but is a close cousin in the larger citrus family, Rutaceae. It is more closely related to Sichuan pepper. It is native to southern Florida and Texas in the United States, and to Mexico, Central America, the Caribbean, and South America as far south as Paraguay. Common names include: lime prickly-ash, wild lime, colima, uña de gato, and corriosa.
