Dendrocnide excelsa
''Dendrocnide excelsa'', also called Australian nettle tree, fibrewood, gimpi gimpi, giant stinging tree, gympie,〔(【引用サイトリンク】chapter=Sorting Dendrocnide names )〕 is a rainforest tree of 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.
== Sting ==
The hairs of the tree exist on all aerial parts, and can cause a severe reaction when in contact with human skin, so it is a hazard to livestock, travelers and campers. Even so, the tree is an important member of the ecosystems of eastern Australian forests. The sting is considered more severe than ''Dendrocnide photinophylla'' (shining-leaved stinging tree), but not as severe as ''Dendrocnide moroides'' (gympie stinger).
Minor stings can last for an hour or two. However, severe stinging can last for months. First aid for the sting is to apply wax hair-removal strips and then yank them off to remove the hairs.〔Hurley M (2000) Foliage Attributes and Growth Dynamics of Stinging Trees (''Dendrocnide'' spp.) in northern Australian upland tropical rainforest: implications for herbivores. Australian Journal of Botany, 48:191-201.〕 ''Dendrocnide'' stings have been known to kill dogs and horses that have brushed against them.〔〔(【引用サイトリンク】title=Dendrocnide )〕
Marina Hurley, a leading researcher of stinging trees, found the only way she could handle the plant to study it was with heavy welding gloves.
