This is a thorny, spreading deciduous tree which can grow up to 8 metres high and 10
metres wide, with densely branched stems. Branches are dense and zigzagged with a
leaf and a thorn at each angle.
Leaves are oval but uneven at the base. They have minutely toothed margins and are
glossy green above and almost white beneath. Leaves are arranged on alternate areas
of the stem.
Flowers are small, greenish-white and arranged in clusters in the leaf axils and have
an unpleasant smell. It can flower all year round.
Fruits are round and edible. They are pale yellow or orange when ripe, and similar in
size and structure to a cherry.
Habitat in the drier parts of the tropics, this tree can be widespread in cleared and
exposed areas, along watercourses, and areas of sparse vegetation. It occurs in a wide
range of soil types but does not establish successfully under the canopy of other trees.
Weed characteristics form dense thickets which restrict stock management, access,
and land productivity. This tree will regrow from root parts left behind if removed at
Dispersal occurs mainly via birds and feral pigs.
This species is a Class 2 declared plant under Queensland legislation
How to act
Mechanical control is most cost effective for initial removal of dense infestations, but this is not advisable on steep slopes or other areas prone to erosion. Windrowing and burning to remove the debris will allow for regeneration of natural vegetation. Cut stump or basal barking is effective for isolated established plants. Young plants can be physically removed. Foliar spraying is most effective when plant is actively growing. Use a broad-leaved selective herbicide to avoid damage to grasses. Control should be carried out prior to seed set with follow up monitoring and control of emergent growth important.
