Eucalyptus smithii, or gully gum, is a native tree of northern Victoria and southern New South Wales, Australia. It naturally occurs on the lower slopes, gullies, and swamps, where soil does not dry out. The species is widely grown in southern Africa, and its leaves are used for the production of distilled eucalyptus oil. The oil is high in cineole (75–84%). E. smithii also shows some promise in the pulpwood industry.
