Manchineel (Hippomane mancinella) is a dangerously poisonous tree reaching up to 15 meters in height with alternate shiny green leaves and spikes of small green flowers.  The fruit is greenish to yellow-green at ripeness.  In less than an hour, severe dermatitis takes effect.  This poisonous tree can be found in the Southern parts of Florida as well as many parts of the Caribbean, Central America, and Northern South America.

Has anybody encountered the Manchineel Tree and got burned?
