Eucalyptus dumosa, commonly known as the Walkerie mallee, Congoo mallee, Cong mallee, Dumosa mallee or the White Mallee, is a mallee of south eastern Australia. Mallee is the Wergaui/ Wotjobaluk word for this species.
The tree typically grows to a height of 4 to 8 metres (13 to 26 ft) and occasionally 12 metres (39 ft) and a width of 4 to 5 metres (13 to 16 ft) and has an open canopy. It has an open, bushy, spreading habit. 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. The bark sheds in long thin ribbons.
Clusters of white flowers appear in late summer to mid autumn. The infloresences are seven-flowered umbellasters with a terete or angular peduncle that is 10 to 16 mm (0.39 to 0.63 in) long. It has pedicels that are terete and 1 to 3 mm (0.04 to 0.12 in) long and cylindrical buds. The fruit that forms later is cylindrical or ovoid and 6 to 9 mm (0.24 to 0.35 in) in length with a diameter of 5 to 7 mm (0.20 to 0.28 in).
It is found in 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. E. dumosa is usually co-dominant in mallee shrubland on red aeolian sands.
It is used as a component of mass plantings along with other mallee species on wide roadside verges as a screen, wind-break, erosion control or a shade tree. Indigenous Australians use the tree as a source of food, drink, medicines and to make containers and implements.
