This is a native species, which is common in the dry and wet zones of the country up to an altitude of about 1000 meters. It is also found in South India.
The conservation status of this species is regarded as Least Concerned (National Red list 2012).
The seeds, bark and leaves are used in Ayurveda medicine to treat digestive ailments, nervous system related diseases and fever.
This is also a host plant for five species of beautiful butterflies found at Wilpattu. The females of the Lime butterfly, Lime Blue, Common Mormon, Quaker and Blue Mormon lay their eggs on the leaves of this species.
This species can often be over looked when the plant is not in bloom. It is a common species at Wilpattu found through out the park. I photographed the above flowers on the Kimbula Ketu Gala road.
