Such introductions probably occur frequently as natural phenomena. Exotic tree species are species introduced to an area where they do not occur naturally. Such species must initially be planted, but may be able to regenerate naturally later. There is a plant that is really deadly to humans and that is the elegant.
Rafflesia arnoldii this blossoms of which are crimson, magenta or creamy white, is one of the most toxic plants in the world. Every part of the plant, from its stem to its sap, is incredibly poisonous if ingested. This flower is also called the corpse flower because its a silent killer.
