Dendrocnide sinuata, commonly known as the Stinging Tree, is a species of plant native to rainforests in Australia. It belongs to the Urticaceae family, which includes other plants known for their stinging hairs. The Stinging Tree is particularly infamous for the potent and painful stings delivered by tiny, hair-like structures covering its leaves and stems.

The stinging hairs of D. sinuata contain a complex mixture of toxins, including histamine, serotonin, and acetylcholine. Upon contact with human skin, these hairs can cause an intense and long-lasting burning sensation, accompanied by welts and other allergic reactions. The effects of the sting can last for days or even weeks, leading to a condition known as “gympie-gympie” or “stinger” dermatitis.

Due to the severity of its stinging properties, the Stinging Tree is considered one of the most notorious plants in Australia. Its presence in the rainforest ecosystem serves as a defense mechanism against herbivores, deterring animals from browsing on its foliage. The cautionary reputation of Dendrocnide sinuata highlights the need for careful navigation in rainforest environments where this plant is found.
