Dendrocnide is a genus of 37 species of shrubs to large trees in the nettle family Urticaceae. They have a wide distribution across Southeast Asia, North East India, Australia and the Pacific Islands. They are colloquially known as stinging trees, stinging nettles or nettle trees. One Australian species, Dendrocnide excelsa (giant stinging tree), can grow to over 40 metres in height, but the dangerous Dendrocnide moroides (gympie-gympie) is only shrub-size. Dendrocnide species are used as food plants by the larvae of some Lepidoptera species, including Aenetus scotti.
