The button leaves upper right belong to D. nummularia a frequent semi parasite of the ant & plant mutualism in Australia. However, D. nummularia is a frequent inhabitant of ant gardens in south Asia where it is perforce a mutualist because co-evolved ant species are attracted to its seed by olfactory lures. The ants place them in their arboreal ant-carton nests where they germinate and grow alongside other similarly co-evolved plants, thus creating what are called arboreal ant-gardens.
