Notes. In recent years Wonga vine has become established in Marri/Jarrah woodlands on the Darling Plateau where it is a particularly serious weed. A long lived perennial woody climber it forms dense layers in low canopy and prevents the establishment of native plant seedlings. It reaches into the canopy of taller trees and appears to reduce growth and recruitment. Tolerates hot to cool temperatures and high to moderately low rainfall. Wonga Vine has distinct juvenile and adult leaves. The juvenile leaves have 8-17 small leaflets. The adult leaves have 3-9 linear to narrowly ovate leaflets. Seed pods are a dark brown oblong-ellipsoid capsule with thick woody valves. Seeds are orange, semi-flat ovoid to 10 mm long and 7 mm wide, with papery wings.
