Dendrocnide moroides, also known as the stinging bush, gympie stinger, mulberry-leaved stinger, gympi gympi, stinger or moonlighter, is a large shrub native to rainforest areas in northeastern Australia, the Moluccas and Indonesia.
It is best known for stinging hairs which cover the whole plant and deliver a potent neurotoxin when touched. It is the most virulent of the Australian species of stinging trees.
The sting causes an extremely painful stinging sensation which can last for days or even months, and the injured area becomes covered with small, red spots joining together to form a red, swollen mass. The sting is known to be potent enough to kill humans, and it can also kill dogs and horses.
