About

Dendrocnide excelsa, commonly known as the giant stinging tree or fibrewood, is a rainforest tree in the nettle family Urticaceae, which is endemic to eastern Australia. It occurs from Tathra, New South Wales to Imbil in southeastern Queensland, and is very common at Dorrigo National Park and other rainforest walks in eastern Australia. The habitat of the giant stinging tree is subtropical, warm temperate or littoral rainforest, particularly in disturbed areas, previously flattened by storms or cyclones. It is well known for its extremely painful, long-lasting sting.

Uses

Indigenous Australians used the fibres to make nets and lines.
