Eucalyptus ovata, commonly known as Swamp Gum or Black Gum, is a widespread occurring Australian eucalypt. The species was first described in 1806 by Jacques Labillardière in Novae Hollandiae plantarum specimen.[2] The locality given in that work is "in terrâ Van-Leuwin", indicating Southwest Australia, but the species does not occur in that region.


The swamp gum is a small to medium-sized tree, rarely a mallee, with bark that sheds over most of the trunk revealing a smooth, grey, whitish or pinkish-grey surface. The rough bark is retained at the base on larger trees. Leaves are stalked, broad lanceolate, undulate to 19 x 8.5 cm dull and green. White flowers appear in autumn to mid-winter. It can reach a height of 30 metres.[3] It is variable in habit from straggly saplings (in east Gippsland) to stout boled trees.[4]

Distribution and habitat[edit]

The tree is widespread from the western end of Kangaroo Island, the southern Mount Lofty ranges and the south-east of South Australia, Tasmania, the southern part of Victoria and south-eastern New South Wales, preferring valleys and poorly drained flat areas.
