Eucalyptus dumosa, commonly known as the Walkerie mallee,[1] Congoo mallee, Cong mallee, Dumosa mallee[2] or the White Mallee, is a mallee of south eastern Australia. Mallee is the Wergaui/ Wotjobaluk word for this species.[3]

Description[edit]

The tree typically grows to a height of 4 to 8 metres (13 to 26 ft)[4] and occasionally 12 metres (39 ft)[5] and a width of 4 to 5 metres (13 to 16 ft) and has an open canopy. It has an open, bushy, spreading habit.[4] 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.[6] The bark sheds in long thin ribbons.[5]

Adult leaves are stalked, alternate, lanceolate 10 centimetres (3.9 in) long and 2 centimetres (0.8 in) wide, concolorous dull green to grey-green.[6]

Clusters of white flowers appear in late summer to mid autumn.[6] 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).[5]

Range[edit]

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.[3] E. dumosa is usually co-dominant in mallee shrubland on red aeolian sands.[5]

Uses[edit]

The leaves are steam distilled as a commercial source of cineole based eucalyptus oil.[7]

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.[4]

A sweet manna-like substance is produced upon the leaves of the tree, it is made into a drink. The bark of young roots is baked and eaten, it is sweet, resembling malt in flavour.[8]
