Description
Dendrocnide is a small genus of trees and shrubs native to Australia, also known as the stinging trees. These plants are widely distributed throughout the eastern coast of Australia and are known for their stinging hairs, which can cause severe pain and allergic reactions in humans and animals. The stinging hairs are found on the leaves, stems, and fruit of the plant, and even brushing against them can cause intense pain that can last for days or weeks.
