An illustration of a manchineel tree stem and fruit. The Manchineel tree (Hippomane mancinella) is a species of flowering plant in the spurge family (Euphorbiaceae), native to Florida in the United States, the Bahamas, the Caribbean, Central America, and northern South America. The name "manchineel" (sometimes written "manchioneel") as well as the specific epithet mancinella is from Spanish manzanilla ("little apple"), from the superficial resemblance of its fruit and leaves those of an apple tree. A present-day Spanish name is in fact manzanilla de la muerte, "little apple of death". This refers to the fact that manzanilla is one of the most poisonous trees in the world

Mangroves (generally) are trees and shrubs that grow in saline coastal habitats in the tropics and subtropics. The word is used in at least three senses: (1) most broadly to refer to the habitat and entire plant assemblage or mangal, for which the terms mangrove swamp and mangrove forest are also used, (2) to refer to all trees and large shrubs in the mangal, and (3) narrowly to refer to the mangrove family of plants, the Rhizophoraceae, or even more specifically just to mangrove trees of the genus Rhizophora. Mangals are found in depositional coastal environments where fine sediments, often with high organic content, collect in areas protected from high energy wave action.
