Manicheel tree: A dangerous tropical tree whose sap is highly poisonous and corrosive. The sap comes out when a leaf is crushed, a branch broken, or the fruit of the tree eaten. The manicheel is hazardous to stand under for shelter from the heat of the tropical sun or, worse, the rain.
The formal botanical name of the manicheel is Hippomane mancinella. In French, the tree is called a "mancenillier" and in Spanish, a "manzana" meaning apple.
