ගිනි-කැන්ද[Gini-kandha]/Bleeding-heart tree(Homalanthus populifolius)

Probably an introduced tree native to Australia & New Guinea* (Also in Malaysia and Pacific islands) though it was considered as a doubtfully native in Sri Lanka#. It occurs in both primary and secondary forests in the hill country from  1550 m to 2000 m elevations, usually in areas adjacent to tea estates.
