Highly variable, thorny shrub or small tree, 2-4m tall (occasionally up to 10m).
Forms dense thickets, shading out useful pasture species preventing stock movement and decreasing biodiversity. For more information see the Queensland Government
Stems are yellowish or brownish white. Branches are armed with pairs of spines. Leaves are dark green above, paler below, in opposite pairs, usually with 1 of the pair smaller than the other. Leaves are generally ovate, 1-10cm long, 1.5-6cm wide, pointed at the apex. Younger leaves are 3-lobed, older leaves not lobed, with sparse hairs on undersides.
Flowers are yellow, tubular, generally around 5cm long. Fruit is yellow when ripe, pear-shaped, about 1.5cm across. Fruits have 4 chambers in which seed can be found, though usually only 2 chambers have fully developed seed.
Spread mainly by bird-dispersed seeds. Woody taproots can produce suckers, particularly after disturbance.
