It frequently grows in heavy soils subject to periodic inundation. There are occasional records for another four Aeschynome species in this area- two native and two introduced. Environmental weed. They all have pinnate leaves with many leaflets, small pea flowers in few-flowered sprays and jointed pods that break up at maturity. The introduced species are: American jointvetch (A. americana) – native to Central and South America – a shrub to 2m densely covered with glandular hairs. Records from northern coastal sites only. A.villosa – a New World species – herbaceous prostrate or weakly erect plant to about 60cm, stems covered with tubercle-based spreading hairs. Records primarily from Whitsunday area.|
