Dendrocnide Moroides/Gympie-Gympie Plant

The Dendrocnide Moroides, or gympie-gympie, is a deadly plant. In real life, these plants inflict an extremely damaging sting towards those who interact with them.

These plants could be added to Minecraft, and spawn in perhaps Jungles. These plants would inflict a powerful poison, (stronger than normal poison), to mimic its damaging sting in real life. 

Plus, the plant could be harvested and used as a defense mechanism by players.

Also, adding these plants to Minecraft could educate people about these plants in the real world.
