Eucalyptus dumosa, White Mallee is a mallee of the relatively dry country of South Australia from the northern Flinders Ranges and Murray Mallee eastwards to central western New South Wales and north western Victoria. Mallee is the Wergaui/ Wotjobaluk word for this species.
The bark is smooth, whitish or yellow-white, weathering to grey or pinkish-grey, on larger stems there is usually a stocking of thin grey-brown fibrous bark.
Adult leaves are stalked, alternate, lanceolate 10 x 2 cm, concolorous dull green to grey -green.
Clusters of white flowers appear in late summer to mid autumn.
The leaves are steam distilled as a commercial source of cineole based eucalyptus oil.
