Description

They grow as slender shrubs up to three metres tall with a stem diameter up to 50 cm (20 in). The leaves are pinnate and alternate with four or eight leaflets. The leaflets form a distinctive triangular shape, broad at the tip and terminating in a point at the petiole. In many plants, the broad apex carries two outer and one inner points, producing a pattern similar to the webbing between the toes of waterbirds, and giving rise the common name duckfoot.

The fruits are orange to yellow capsules with three lobes. Inside each lobe there is a glossy dark brown seed. Each seed is covered in a bright orange aril. Fruits ripen from October to December, attracting many birds.
