|Etymology||Genus||Common name of the plant in Philippines|
|Common Names||Common Mahang|
|Native Distribution||Malesia, Thailand|
The Common Mahang has a mutualistic relationship with the Heart Gaster Ants (Crematogaster species) (BESG, 2020). It feeds off the starchy white globules inside the stipules, and also farm scale insects in the hollow stem where it lives in. In return, the ants are said to fend off the plant from vines and herbivores.
This is also the host plant of the butterfly, Arhopala amphimuta amphimuta. The ants will attend to the caterpillars while milking them for their sugary secretions.
