The Mongarlowe Mallee is a many-stemmed shrub (mallee) that grows to 4 m tall. Its bark is smooth and mottled grey and orange-brown, shedding in short ribbons. The glossy-green leaves are arranged in pairs, to 3 cm long and 8 mm wide. The white flowers are arranged in clusters of three, on a common stalk to 5.5 mm long. Each cluster arises from the axil of a leaf, and several clusters are produced towards the ends of the branchlets. The main distinguishing character of this species - from which its name is drawn - is its conspicuously recurved leaf tips. These are very rare in eucalypts, and are much more developed in Mongarlowe Mallee than in any of its close relatives.


The Mongarlowe Mallee is confined to the NSW Southern Tablelands where it is known from only four locations. Three of these occur near Mongarlowe (with at least a two km separation between the sites) and the third is about 30 km away near Windellama. Three of these sites support what are believed to be only single plants, whilst the other has two individuals present - the total known population of this species is only five individuals. It is likely that these individuals represent a relict of a more widespread ancestor, and it is unlikely that further extensive populations of the species remain undiscovered.

Habitat and ecology

  • Found in shallow soils on gentle slopes in low heathland and in some cases at the margins of the heathland and adjacent low woodland; the woodlands are dominated by Brittle Gum (Eucalyptus mannifera) and Snow Gum (E. pauciflora), but scattered Candlebark (E. rubida) and Broad-leafed Peppermint (E. dives) trees are also nearby at some sites; in the Mongarlowe area the heathland is dominated by Stunted She-oak (Allocasuarina nana), with emergent shrubs of Finger Hakea (Hakea dactyloides).
  • Flowering occurs in January, sets very few seeds so the chances of recruitment of new individuals in the field is low; efforts by CSIRO to cross-pollinate the two plants near Mongarlowe to produce viable seed and to propagate the species using grafting and tissue culture techniques in 1992 were unsuccessful.
  • The size and spread of the lignotubers (woody underground structures) suggests that the plants are of considerable age, probably several hundred years.
