Giant Stinging Tree (Dendrocnide excelsa)
Description
Dendrocnide excelsa, also called Australian nettle tree, fibrewood, gimpi gimpi, giant stinging tree, gympie, 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. Dendrocnide excelsa is a medium to large-sized tree with a buttressed base, sometimes over 40 metres tall and in excess of 6 metres wide at the butt. The trunk can be fluted or flanged. The outer bark is grey and smooth, with minor corky markings. The trunk and buttresses are shaped in even curves. The leaves are alternate and toothed, heart-shaped and very large in positions of shade, exceeding 30 cm in length and a similar width. The sun leaves are smaller. The leaves are replete with stinging hairs, and are eaten by various insects and mammals, such as the chrysomelid beetle. Flowers appear from November to April, forming in short panicles. The fruit is a purple or blackish nut, maturing from March to August. The flesh is edible, but the danger of stinging hairs precludes human consumption. The fruit is eaten by many rainforest birds, including the regent bowerbird and the green catbird.
