Behavior
This species of tree is a myrmecophyte and it has a mutualistic relationship with ants, including "Pseudomyrmex triplarinus". This kind of ant lives within the tree, feeding on substances produced by it and defending it against invaders. This tree is known as a "novice tree" because only one unfamiliar with the tree would touch it, soon discovering that the ants are aggressive and venomous.Habitat
This tree grows in riparian habitat types, and is a colonizer of disturbed habitat. It has been introduced to areas outside its native range, including Hawaii and southern Africa.References:
